"Hypertension is a major public health problem in the U.S. and worldwide. More than a quarter of world's adult population totaling one billion, have it. The National Health and Nutrition Examination Survey predicted that 63.3 million Americans ( 20 percent of the population) are hypertensive (Systolic BP more than 140 and Diastolic BP more than 90). It is the second most prevalent chronic disease and accounts for $33 billion in direct cost and $280 billion in lost production every year." - Clinton Herald
"Researchers at the University of California, Davis have discovered that a prototype drug reduces heart enlargement, one of the most common causes of heart failure. Heart failure, which occurs when the heart can't pump enough blood throughout the body, affects 5 million people in the United States. The condition contributes to 300,000 deaths each year. The research in the laboratories of cardiologist and cell biologist Nipavan Chiamvimonvat, Department of Cardiovascular Medicine, UC Davis School of Medicine, and entomologist Bruce Hammock, Department of Entomology, showed that the new class of drugs reduces heart swelling in rat models with heart failure. 'This holds promise to treat heart failure and other cardiovascular as well as kidney problems,' said nephrology professor Robert Weiss, Department of Internal Medicine" - Science Centric
"A defective gene causes sudden cardiac death in many young people, says a new study. Researchers at Johann Wolfgang Goethe University have found that in at least ten per cent of cases in Europe, sudden cardiac death in young people is due to a cardiac gene defect, the 'Deutsches Arzteblatt International' journal reported. Sudden cardiac death is defined as unexpected death occurring rapidly - usually within one hour of the onset of symptoms - in persons previously seemed to be healthy" - Zeenews

"Stroke Awareness Day falls this year on Tuesday 12 May. This is a European-wide initiative developed through The Stroke Association's membership of the Stroke Alliance for Europe (SAFE); stroke awareness activities will be taking place simultaneously in member countries all over Europe. To mark the day, The Stroke Association is planning a range of exciting activities around the UK. These include Stroke A-wear-ness Fashion Shows featuring our service users and stroke club members, blood pressure testing and information events, fundraising events such as skydives and street collections, and we are once again running the very popular Step up for Stroke" - Stroke Association (UK)
"A paper co-authored by Beatrice Golomb, MD, PhD, associate professor of medicine at the University of California, San Diego School of Medicine and director of UC San Diego's Statin Study group cites nearly 900 studies on the adverse effects of HMG-CoA reductase inhibitors (statins), a class of drugs widely used to treat high cholesterol. The result is a review paper, currently published in the on-line edition of American Journal of Cardiovascular Drugs, that provides the most complete picture to date of reported side effects of statins, showing the state of evidence for each. The paper also helps explain why some people have a higher risk than others for such adverse effects. 'Muscle problems are the best known of statin drugs' adverse side effects,' said Golomb. 'But cognitive problems and peripheral neuropathy, or pain or numbness in the extremities like fingers and toes, are also widely reported.' A spectrum of other problems, ranging from blood glucose elevations to tendon problems, can also occur as side effects from statins. The paper cites clear evidence that higher statin doses or more powerful statins - those with a stronger ability to lower cholesterol - as well as certain genetic conditions, are linked to greater risk of developing side effects." - newswise
"A bad economy can take its toll on the heart with increased stress, poor eating and forgoing healthful activities like going to the gym when money is tight. UCLA cardiologists suggest the following tips to help protect the heart during this time of financial uncertainty. 'We've seen an increase in patients complaining about heart palpitations, anxiety and stress over the past months,' said Dr. Karol Watson, associate professor of cardiology, David Geffen School of Medicine at UCLA. 'Much of heart disease can be prevented, that’s why it is so important to follow a healthy lifestyle and to control your cardiovascular risk factors.'" - newswise
Researchers in Australia are reporting an advance toward the first urine test for diagnosing coronary artery disease, the condition responsible for most of the 1.5 million heart attacks that occur in the United States each year. The test could save lives in the future by allowing earlier diagnosis and monitoring of the disease, which is the No. 1 cause of death in the United States, the researchers say. Their report is in the November 19, 2008 issue of ACS' Journal of Proteome Research
"Could the humble worm hold the key to wiping out allergies and a whole lot of disorders of the immune system? Researchers in Nottingham are investigating whether giving hook worms to asthma sufferers can cure their condition. Another group in the US is trying a pig worm on patients with ulcerative colitis or inflammation of the colon and bowel. And scientists in Cambridge have proved that giving an extract of the tropical worm which causes billharsia to mice can stop them developing type 1 diabetes" - BBC

"Rigorous exercise of short duration can significantly affect the body's ability to process sugars and fight diabetes, a new study suggests. In research published in the journal BMC Endocrine Disorders, scientists from Heriot-Watt University in Edinburgh, Scotland, say they found that brief but intense exercise every day or two may help reduce the risk of diabetes. James Timmons, a professor in the school of engineering and physical sciences, says he and a team of investigators looked into the effect of "high-intensity training" on the insulin action and blood sugar control in 16 young, healthy male volunteers. They found that insulin sensitivity improved significantly in the two-week study. Regular exercise can help reduce the risk of type 2 diabetes and heart disease" - WebMD
"Sunday was the first day that 7-year-old Emily Smith was able to visit the hospital playroom since receiving her new heart. It is a small step to getting her life back to normal. "You can tell that she wants to play soccer but she can't. Now that she has her heart, she can," said her big sister, Shayde. Shayde is 9 and knows a bit about what Emily is going through. She has the very same condition, called restrictive cardiomyopathy, in which the heart doesn't relax as it should between pumps, so it doesn't properly fill with blood. "Less than 1 in a million are diagnosed with this type of heart disease," Dr. Kristine Guleserian of Children's Medical Center in Dallas told CBS News correspondent Hari Sreenivasen. "To have two family members, it is even more rare. To have two sisters with it who are so close in age is incredibly rare."" - CBS
"Cardiologists at Saint Louis University are participating in what they say are the first-ever clinical trials of gene therapy to treat severe heart failure. Researchers say it could be the first to not only treat symptoms of heart failure but to actually reverse the severity of the disease. Saint Louis University is among 13 research centers involved in the project. The study will investigate whether MYDICAR, a genetically targeted enzyme replacement therapy, can repair heart muscle that was damaged by either a prior heart attack or heart muscle disease. Heart failure affects about 5 million Americans" - KSDK.com
"We know that a low salt diet is important to control high blood pressure that leads to heart disease. According to new research from Loyola University, it seems equally as important to increase our potassium intake if we really want to reduce our risk of heart disease. According to study author Dr. Paul Whelton, president and CEO of Loyola University Health System, "There isn't as much focus on potassium, but potassium seems to be effective in lowering blood pressure and the combination of a higher intake of potassium and lower consumption of sodium seems to be more effective than either on its own in reducing the risk of cardiovascular disease." - maxHealth
"England has been exposed as the sick man of Europe, with the highest rates of obesity. More women die of alcoholic liver disease and cancer here than in almost any other country. Heart attack and smoking rates were among the highest, and infant mortality was among the worst on the continent - despite billions of pounds pumped into the NHS. Critics immediately seized on the findings, saying Labour's failed policies risked bankrupting the Health Service. The damning survey, the Health Profile of England 2008, was published by the Government. It compares the nation's health with the 15 western European countries which were part of the EU before 2004 - the 'EU-15'. "

"The Rev. H.L. Deason looked around his new room Monday with admiration. "I like the colors," the retired Baptist preacher said. "Very easy on the eyes." The Rev. Deason got a new room without ever leaving University Hospital. He was among the first to transfer into the new Heart & Vascular Institute, Augusta, Georgia. The addition, which staff are calling "the tower," began getting patients Sunday, and the transfer from the hospital's cardiac units to its 72 patient rooms will go through Wednesday. The institute is the largest and most visible piece of University's $93.6 million renovation, which is all but complete now as patients and staff move in." - Augusta Chronicle

"In a finding that could save thousands of lives a year, University of Utah School of Medicine researchers have shown that a blood vessel disorder leading to unpredictable, sometimes fatal, hemorrhagic strokes, seizures, paralysis or other problems is treatable with the same statin drugs that millions of people take to control high cholesterol. If the results of a study in mice are confirmed in a pilot trial with people, statins could provide a safe, inexpensive treatment for cerebral cavernous malformation (CCM), a disorder with no known drug therapy, according to U of U cardiologist Dean Y. Li, M.D., Ph.D., director of the Molecular Medicine Program and corresponding author of a study published January 18 in Nature Medicine online" - EurekAlert

"After two weeks sitting by his wife's bedside hoping she would wake from a coma, Andrew Ray was at his wits' end. Doctors had told him Emma could become a real-life sleeping beauty when she failed to regain consciousness after a heart attack. The distraught father of two played her tapes of their baby son crying and their daughter shouting 'wake up Mummy!'. Finally, in desperation, he leant over her hospital bed and pleaded: 'Emma, if you can hear me, please just give me a kiss. 'What happened next was beyond my wildest dreams,' he said. 'She turned her head towards mine, puckered up her lips and gave me a little kiss.'" - The Mail
"The United Kingdom is cultivating hidden hotbeds of heart disease, the British Heart Foundation can reveal today. Recent reports of declining death rates at a national and regional level are hiding the grim reality for those living in significant pockets of deprivation, according to our new figures. In some local authority areas, people living in one ward are five times as likely to die from heart disease as those living just half a mile away. The new figures highlighting potential future 'supercentres' of heart disease were released by the BHF as we launched a major new GBP9 million programme to tackle inequalities in heart disease. The BHF's UK-wide Hearty Lives programme will give those born into deprived areas a greater chance of living to see their grandchildren grow up, and better support if they do develop heart disease."

The other states within the top ten for highest annual smoking death rates were Nevada, Mississippi, Oklahoma, Tennessee, Arkansas, Alabama, Indiana and Missouri. Utah and Hawaii had the lowest smoking death rates. According to the study, Kentucky had 371 smoking related deaths out of every 100,000 adults age 35 and older. The report appears in this week's edition of the CDC's Morbidity and Mortality Weekly Report" - redOrbit
"Fainting is the most common in-flight medical emergency. Research recently published in BioMed Central's open access journal Critical Care details the number, type and frequency of medical emergencies on board two airlines. Michael Sand led a team of researchers from the University of Bochum, Germany, and the University of California Los Angeles (UCLA), who analyzed 10,189 different emergencies. He said, 'Although in-flight medical emergencies are rare in general, they can have a significant effect on other passengers and crew, potentially with operational implications for the flight. The breakdown of the various medical emergencies encountered in our study showed that fainting was by far the most frequent medical condition, followed by stomach upsets, and heart conditions'."
"Now that the 11-hour-long repeat bypass surgery on Indian prime minister Manmohan Singh is over, the focus has shifted to his post-operative care and cardiac rehabilitation. According to cardiologists, when it comes to heart patients, post-operative care is as important as the surgery. "Cardiac rehabilitation is a multi-dimensional programme designed to reduce future risk of heart patients through medical evaluation, prescribed exercise, cardiac risk factor modification, education and counselling," said Dr Aashish Contractor, who heads the Preventive Cardiology and Rehabilitation Centre, Asian Heart Institute. DNA has learnt that doctors from the Asian Heart Institute's Preventive Cardiology and Rehabilitation Centre will also be joining Dr Ramakant Panda's team in Delhi on Monday" - DNA

"A study from the University of Bath has found that smokers are twice as likely to kick the habit if they use a support group rather than trying to give up alone. Researchers from the UK Centre for Tobacco Control Studies led by Dr Linda Bauld at Bath, along with colleagues from the University of Glasgow, have published research in the February issue of Addiction journal comparing the success and cost-effectiveness of two types of stop smoking support services offered by the NHS. These are community-based group stop smoking support and one-to-one support provided in a pharmacy setting. The study, funded by the Glasgow Centre for Population Health, NHS Greater Glasgow and Clyde and Health Scotland, found that more than a third of smokers using support groups quit smoking after four weeks; almost double the proportion of those using a pharmacy-based support scheme to help them quit." - EurekAlert
"The UK is a country obsessed by the threat of obesity. As the average person's weight has grown, so has coverage of the subject. The chief medical officer for England, Sir Liam Donaldson, has said we are facing an "obesity timebomb". Culinary celebrities like Jamie Oliver have launched campaigns, in homes and school kitchens, to fight the fat war. Yet the science of weight gain is less straightforward than the headlines sometimes suggest. Why, for example, do some people seem to eat what they like and not put on weight, while others limit their diet yet struggle to shed their bulk?" - BBC
"Patients with abnormal diastolic function - the heart is relaxed and expanded - in the left ventricle have a lower exercise capacity, U.S. researchers say. Dr. Jasmine Grewal of the Mayo Clinic in Rochester, Minn., and colleagues studied the relationship between left ventricular diastolic function and exercise capacity. The study included 2,867 patients undergoing exercise echocardiography - a noninvasive diagnostic procedure that uses ultrasound to study the structure and motions of the heart. The patients had routine measurements of left ventricular systolic - contraction of the heart - and diastolic function. Analyses were conducted to determine the strongest correlates of exercise capacity and the age and sex interactions of these variables with exercise capacity. The study, published in the Journal of the American Medical Association, found that diastolic dysfunction - impaired relaxation - was strongly and inversely associated with exercise capacity. Compared with normal function, those with resting diastolic dysfunction had substantially lower exercise capacity, the study said" - UPI
Reducing the salt in your diet can help lower your blood pressure, but it may also lower your risk for having a heart attack or stroke in another important way. Results from a new study suggest that eating a low-sodium diet can also help keep blood vessels working properly. The study measured the impact of salt restriction on the endothelium, the thin layer of cells that line the interior of the blood vessels and help regulate blood flow. Overweight and obese study participants with normal blood pressure who restricted the sodium in their diets showed evidence of improved endothelial function compared to participants who did not restrict salt. The improvement appeared to be unrelated to the impact on blood pressure, suggesting that salt restriction is independently protective of blood vessel function. "We found that if we reduced the salt in the diet, we saw a direct, positive impact on blood vessels," nutrition researcher and study co-author Jennifer B. Keogh, PhD, tells WebMD.
"Jackson-Madison County General Hospital, Tennessee, has announced the opening of its new Chest Pain Center.

"Two-thirds of Birmingham, UK, residents are overweight and half of those are clinically obese, according to a public survey carried out by a health firm. The study of 1,350 adults found "worryingly high" levels of high blood pressure and high body fat. It found the lowest levels of obesity are in south-west London, where one third are overweight and 13 per cent obese. The survey, based on as series of 'health checks' in 13 locations across Britain, also discovered that obesity is occurring at an increasingly young age. In Manchester, it found the average age of the overweight population was 28, compared to 47 in Birmingham. The research was carried out by health brands Salter and HoMedics" - Telegraph
"A gym is offering its customers an unusual set of dumbbells to exercise with - including an overweight man and two dwarfs. Members of Gymbox in Bank, central London, can choose to lift any of five differently sized "human weights". Wearing Lycra catsuits which label their weight, they sit on specially adapted machines and shout words of encouragement. The "dumbbells" include two dwarfs - 32-year-old Arti Shah, who weighs just 4.5 stones (30kg) and 64-year-old Mike Edwards, who weighs 8 stones (55kg). At the other end of the scale for those with stronger muscles is 24 stones (155kg) Matt Barnard, 37. Gymbox owner Richard Hilton said: "A lot of our members felt that lifting metal weights was boring and not especially motivating." - Telegraph
"Exercise may be good for the heart, but good diastolic function also appears to protect the capacity for exercise, researchers found. Any level of resting diastolic dysfunction, whether moderate-to-severe or mild, substantially lowered exercise capacity (both P<0.001), Patricia A.

"Despite education efforts, heart disease is still a leading cause of death in American women. So how do you protect yourself and your loved ones? 'I was in perfect health,' said Louise Bell. 'I took no medication. I was an aerobics instructor. I worked out an hour a day, five to six days a week.' Bell, 47, was a picture of good health. As a flight nurse, her job was to save other people's lives. One day, that all changed. 'I was sitting at my computer early one morning and I just had a crushing pain across my chest,' she said. 'When I felt the pain, I stood and then I sat down and I couldn't get back up.' Bell was having a heart attack, the first of two she would have in just a couple of days time. She had no warning signs and no risk factors. Doctors later told her it was the result of a congenital heart problem called Microvascular Disease, when small blood vessels going to the heart are blocked or have a decreased blood flow" - NBC

Wrist access safer, easier for many patients undergoing minimally invasive treatment of blocked heart arteries
"A new approach to unblocking heart arteries minimally invasively will mean less bleeding, less down time, lower costs and less risk overall, particularly for obese patients, according to data being presented at the 21st annual International Symposium on Endovascular Therapy (ISET). Every year, about one million Americans opt for angioplasty over bypass surgery to open their blocked arteries. New data suggests that beginning the angioplasty procedure by entering through the wrist - rather than through the groin - will make it safer and easier on patients." - redOrbit

"Salt reduction may offer cardio-protective effects beyond blood pressure reduction, researchers in Australia found. Kacie Dickinson of Flinders University in Australia and colleagues said the study provided further evidence of the importance of decreasing sodium intake to improve blood vessel health and reduce the risk of cardiovascular disease. The study, published in the February issue of the American Journal of Clinical Nutrition, showed that sodium reduction is beneficial for people who have normal blood pressure and those who are overweight or obese - and the benefits start in just a few weeks. "Regardless of one's body weight or blood pressure, sodium reduction offers many health benefits," Dickinson said in a statement" - redOrbit
"First heart attacks are less likely to kill people in the United States than they used to be, helped by better prevention efforts and better treatments, U.S. researchers said on Monday.

"Using chopsticks helps you eat less and lose weight, says Kimiko Barber, author of "The Chopsticks Diet." The human brain takes 20 minutes to register what the stomach contains, so using chopsticks slows a person's consumption, leaving them feeling satisfied while eating less, Barber said. Chopsticks users also take smaller bites, which means food tends to be chewed more, making it easier to digest, she told The Daily Telegraph in a story published Saturday. In Britain alone, an estimated 10 million people - 24 percent of the population - are clinically obese, The Telegraph reported, noting a third of the country is expected to qualify as obese by 2012 if eating habits remain the same. Doctors say obesity contributes to heart disease, Type 2 diabetes and many cancers." UPI
"One in 100 people in the world has a gene defect that almost guarantees heart failure, scientists have found. For individuals whose ancestry can be traced to the Indian subcontinent, the risk is much higher. They have more than a one in 25 chance of inheriting the abnormal gene. The mutation, a deletion of 25 letters of genetic code from the heart protein gene MYBPC3, is believed to have first appeared in India thousands of years ago. It is thought to affect around 60 million people worldwide. Researchers studying the gene reported that for anyone unlucky enough to be born with it, heart failure is a virtual certainty. Genetic risk is often expressed as an "odds ratio", with 1.2 indicating a small effect and 2.0 a large one. The findings were published in the journal Nature Genetics." - Channel 4
"Thousands of Canadians with high blood pressure (hypertension) are being treated with a drug combination that increases the risk of sudden cardiac death, kidney disease and the likelihood of dialysis, warns the Heart and Stroke Foundation. New guidelines from Canadian Hypertension Education Program (CHEP) based on international research funded in part by the Foundation will urge patients who have been prescribed a combination of ACE inhibitors and Angiotensin II Receptor Blockers (ARBs) to see their family physicians as soon as possible for a treatment change. 'These two popular categories of hypertension medication are each safe and effective treatments – but not together,' says Dr. Sheldon Tobe, spokesperson for the Heart and Stroke Foundation and CHEP executive member. As many as 175,000 Canadians with high blood pressure may be currently treated with this combination of medications." - Heart and Stroke Foundation
Your chances of surviving a cardiac arrest is only about 10% but doctors are trying to increase those odds by using a new cooling device that may help more patients survive. The Arctic Sun Cooling System is used on cardiac arrest patients who never regain consciousness and it's increasing survival rates to nearly 30% at one West Michigan hospital. Time means everything for cardiac arrest patients, "For many patients their heart recovers but their brain doesn't." Dr. Paul Lange is a critical care specialist for Borgess Medical Center in Kalamazoo, he says once the heart stops pumping blood to the brain, within five minutes your brain cells begin to die and you could sustain irreversible brain damage. That's why doctors and their trained team at Borgess Medical Center in Kalamazoo are trying new technology called the Arctic Sun Cooling Device," Research has shown that by cooling people after cardiac arrest they have a better chance for survival. We believe we are protecting the brain from ongoing injury after the patient is recovered from their cardiac arrest." - WZZM

"Older people who spend more time sleeping have higher cholesterol levels, and less "good" HDL cholesterol, Dutch researchers report. People who sleep fewer than seven hours a night, as well as those who log more than eight hours may be more likely to develop heart disease, although it's not clear why, Dr. Julia F. van den Berg of Erasmus Medical Center in Rotterdam and colleagues note in the medical journal Psychosomatic Medicine. To investigate whether cholesterol might be a factor, van den Berg and her team compared sleep duration and total cholesterol levels, as well as the ratio of total to HDL cholesterol, in 768 men and women 57 to 97 years old." - Reuters

"Routine screening of newborn babies for a life-threatening heart problem can save lives, a Swedish study has found. Researchers found checking blood oxygen levels increased detection of a congenital heart defect which affects up to two in a thousand babies. The British Medical Journal online study says just under a third currently leave hospital undiagnosed, leading to added complications and more deaths. UK experts are investigating if screening should be introduced.

"Two out of three Canadians are not aware of peripheral arterial disease (P.A.D.), a common vascular disease that affects as many as 800,000 Canadians, according to a study published in the Canadian Journal of Cardiology. Commonly known as "hardening of the arteries," P.A.D. occurs when arteries in the legs become narrowed or clogged with fatty deposits, reducing blood flow to the legs. As a result, P.A.D. may cause leg muscle pain when walking and lead to disability, amputation and a poor quality of life. The blocked arteries found in people with P.A.D. are a warning sign that other arteries, including those in the heart and brain, may also be blocked, increasing the risk of a heart attack or stroke" - CNW

"Having a stressful job can double a man's chances of suffering a stroke, a new study has shown. But women under pressure in the workplace do not seem to be at the same risk of stroke, scientists found. The researchers speculate that the difference between the sexes could be because women approach stressful jobs differently to men or because more of them work part-time. Strokes are one of the most common killers in Britain, affecting an estimated 150,000 people each year, of which more than 67,000 die. The study found that there were two major factors which determined how stressed employees felt at work, the demands of the job itself and the amount of control they felt over their day-to-day working life. The findings, published in the Archives of Internal Medicine journal, show that those workers in "high-strain" jobs, which were both extremely demanding and over which they had little control, were twice as likely to suffer a stroke as those in "low-strain" positions" - Telegraph

Early the morning of January 3, Agnes Phillips was sleeping next to her husband Bernie, when she noticed his breathing sounded strange. "I heard an irregular breathing sound, and I thought he was in the middle of a bad dream," recalled Agnes Phillips, 47, a chemistry teacher at Schenectady High School. She tried to awaken her husband. When she got no response, she called 911 and started cardio-pulmonary resuscitation. Minutes later, emergency medical responders from Colonie and Latham arrived at the couple's Latham home and determined that Phillips had gone into cardiac arrest - the abrupt loss of heart function. Death usually begins within four to six minutes. They established an airway, got his heart beating again and rushed him to Albany Medical Center Hospital. Phillips then made history, becoming the first cardiac arrest patient in the Capital Region to be revived using therapeutic cooling - a process by which the temperature of the body is lowered to a near hypothermic state in order to prevent or reduce brain damage. - Daily Gazette Co
"A new study warns that the second generation of antipsychotic drugs, used to treat conditions ranging from schizophrenia to anxiety, put patients at higher risk of sudden death due to cardiac arrest.

"Healthy young adults are not really immune from heart disease; they are likely to carry a higher risk of cardiac complications over their lifetimes, according to new findings. The findings suggest that traditional methods of identifying heart disease risk might not adequately identify patients who actually have a higher lifetime risk. "We found that about half of individuals who are 50 years of age or younger and at low short-term risk for heart disease may not remain at low risk throughout their lives," said Jarett Berry, assistant professor of internal medicine at University of Texas Southwestern and co-author of the study." - NewKerala
"Indiana's casino workers and customers breathe air containing 14 times more secondhand smoke than the air outside, a Purdue University study has found. The study, released by the Indiana Campaign for Smokefree Air and the Indiana Academy of Family Physicians, comes as the Legislature reconsiders a smoke-free workplace law. A similar bill did not make it to the floor last year. Casinos, bars, and private clubs have lobbied against such a law, arguing it would detract from their business and infringe on their customers' rights. But proponents of the bill say this study and others on secondhand smoke show all employees deserve protection" - The Enquirer

University of Ottawa Heart Institute scientists successfully develop novel biomaterial to help grow new blood vessels
"Researchers at the University of Ottawa Heart Institute have successfully grown blood vessels in damaged muscle tissue by injecting a biomaterial developed specifically to attract new cells and support regeneration. Blood vessel regeneration suggests that the body's own cells might one day be used to repair heart damage and restore function. Details of the regeneration process were published online in the Journal of the Federation of American Societies for Experimental Biology. A UOHI cardiac surgery research team led by Erik Suuronen, PhD, in collaboration with Dr. Marc Ruel, showed that thigh muscles with ischemia (lack of blood flow and oxygen) grew a significant number of new blood vessels when treated with the biomaterial"

Saskatoon Health Region is embarking upon an ambitious transformation program that will use technology as a change agent. The goal of the program is to implement an electronic health record (EHR) to improve patient access, safety and outcomes - a key component of the Region's strategic plan. Deploying an EHR is a complex undertaking. One of the many initiatives supporting it is the implementation of a clinical information system - Sunrise Clinical Manager. Evidence demonstrates that clinical information systems have the potential to transform care delivery. If well-designed and adopted by clinicians, the systems improve workflow, patient safety and outcomes, and contribute to efficiencies. Lori Chartier, Director, Clinical Transformation and E-Health, is the Region's lead on the initiative. It's her job to ensure that the design process for the SCM is structured to respect clinicians and their workflows, and allow them to lead the design process.
"Cigarette smokers who try to quit gradually rather than giving up smoking all at once can safely use nicotine-replacement gum, a new study shows. Heavy smokers in the study who chewed the highest doses of nicotine-replacement gum as they tried to cut down on their smoking reported no more side effects than lighter smokers who chewed less nicotine gum. The research was funded by GlaxoSmithKline, which markets Nicorette - the nicotine-replacement gum used in the study.

The report, published in the American Journal of Epidemiology, evaluated 71 existing research papers that looked at similarities for major coronary risk factors in more than 100,000 pairs of spouses." - WebMD
"Falling temperatures in winter may cause an unhealthy rise in high blood pressure in elderly people, according to a new study linking cooler temperatures with higher blood pressure. Seasonal variations in blood pressure have been noted for years, but few studies have looked at these temperature-related effects in one of the most at-risk populations: the elderly. Now a large study from France has shown that blood pressure in elderly people varies significantly with the seasons, with rates of high blood pressure readings rising from 23.8% in summer to 33.4% in winter. Blood pressure increases were seen in both the systolic (top) and diastolic (bottom) numbers. "Elderly persons may be particularly susceptible to temperature-related variations in blood pressure," researcher Annick Alperovitch, MD, of the Institut National de la Sante et de la Recherche Medicale, in Paris, and colleagues write in the Archives of Internal Medicine. "Mechanisms that could explain the association between blood pressure and temperature remain undetermined." - WebMD

"MRI scans could soon be used to show who is at risk of a heart attack. At the moment the only way is to use an invasive probe that can itself trigger cardiac arrest. A major cause of heart attacks is plaques made of immune cells and cholesterol that build up inside the coronary arteries, which feed the heart. If a plaque ruptures, a clot can form, blocking blood flow with potentially catastrophic results. While cameras can be sent into arteries to check the walls for plaques, the probe itself might rupture a plaque. An MRI scan can see inside the body without risk, but doesn't provide enough resolution to image artery walls directly. However, Simon Robinson of Lantheus Medical Imaging in North Billerica, Massachusetts, and his colleagues found a way around this using gadolinium chelate, a substance which is already used to light up blood in MRI scans" - NewScientist

"One of the harshest side-effects of a stroke or a cardiac arrest is the death of a large number of neurons and glial cells, which can often lead to other, hard-to-treat complications, making recovery long-lasting and painful. Doctors are now working on a new way of preventing that from happening, and, while the new method does not address the underlying issue – the damage to the heart – it does help reduce some of its effects. A University of Edinburgh PhD student from the UK is currently testing a 'brain-cooling' helmet that works by inducing a mild state of hypothermia to patients. Taking the old principle of applying cold bandages to the head in order to relieve headaches a few steps further, Bridget Harris, the researcher behind this initiative, devised a helmet of sorts that takes advantage of the intricate network of blood vessels on the scalp, which regularly transport blood to the brain. She argues that cooling the blood before it reaches its destination makes the temperature of the brain go down by as much as 4 °C, to an average level of 33 °C." _ Softpedia

"If you're committed to fitness, the decision to climb a couple of flights of stairs rather than take the elevator is clear. But if you develop chest pain on the way up, deciding how to treat the symptoms of clogged arteries in your heart is much more complicated. Whether it's appropriate to treat chest pain with medical therapy alone or prescribe medical therapy and also perform revascularization - that is, by restoring good blood flow to the heart muscle with a balloon-tipped catheter or bypass surgery-depends on several factors that vary from patient to patient. In some cases the decision is obvious; in others, it's more nuanced. Now physicians, patients and health insurers have a practical tool for weighing each of those factors and arriving at the right treatment decision.
