Cholesterol Crystals Linked to Cardiovascular Attacks

For the first time ever, a Michigan State University researcher has shown cholesterol crystals can disrupt plaque in a patient’s cardiovascular system, causing a heart attack or stroke.
The findings by a team led by George Abela, chief of the cardiology division in MSU’s College of Human Medicine, could dramatically shift the way doctors and researchers approach cardiovascular attacks. Abela’s findings appear in the April issue of the American Journal of Cardiology. 
New Role for Immune System Pathway in Post-heart-attack Inflammation

A new study led by University of Iowa researchers has found an unexpected new link between this inflammation in heart muscle following heart attacks and a previously known enzyme called calcium/calmodulin-dependent protein kinase II or CaM kinase II. The findings also reveal the involvement of an immune system gene--complement factor B--that has been implicated in other inflammatory diseases.
The study, published online March 9 in the Journal of Clinical Investigation, suggests that CaM kinase II inhibition could be a therapeutic target in heart disease, but by previously unknown pathways.
Drugs Before Stents for Stable Heart Disease

Treating people with non-acute heart problems should start with drug therapy, not invasive techniques such as angioplasty or implanting stents, because there is no difference between the two approaches in outcomes, a new study finds.
Stroke: Innovative Team Approach Brings Man Back from the Dead Twice

He was in the throes of a heart attack—the kind so bad it's called "the widow maker." PATCAR was at the rescue, a state-of-the-art response that required three medical teams-from ambulance to cath lab-to all work from the same playbook in precision time. Alive and well, he cheated death twice in one day.
“I died twice,” says a teary-eyed DeWayne Lark, “If I didn’t believe in miracles before, I believe in them now
Louisville test will try to regrow heart muscle

The University of Louisville and Jewish Hospital & St. Mary's HealthCare will conduct a clinical trial using adult cardiac stem cells to try to regrow dead heart muscle after heart attacks.
Heart disease is a major killer in the United States, and in Kentucky, cardiovascular disease kills at one of the highest rates in the nation.
Sudden Cardiac Death Without Recognizable Cause

In about 10% of cases, sudden cardiac death (SCD) in young people is due to a cardiac gene defect.
Gene Ups Risk for Those on Blood-Thinner Plavix

A gene variation can make younger heart attack patients more prone to another heart attack, death or other heart problems if they receive the anti-clotting drug Plavix, a trio of new studies finds.
Preventing a broken heart: Research aims to reduce scarring from heart attacks
piggy submitted, created time 1 year 8 months (www.eurekalert.org)
A heart damaged by heart attack is usually broken, at least partially, for good. The injury causes excessive scar tissue to form, and this plays a role in permanently keeping heart muscle from working at full capacity.
Now researchers have identified a key molecule involved in controlling excessive scar tissue formation in mice following a heart attack. When they stopped the scarring from occurring, the scientists found that the animals' heart function greatly improved following the injury
Lifestyle may link depression and heart disease

The long-standing connection between depression and heart problems might be traceable to the fact that depressed people are less physically active than others, a new study of heart patients shows. A greater tendency in depressed people to smoke and to fail to take medications regularly may also play a role, researchers report in the Nov. 26 Journal of the American Medical Association
Should healthy people take statins too?

The results of a study examining whether a potent cholesterol-lowering drug decreases the risk of heart disease are out. Rosuvastatin was given to 17,802 seemingly healthy people, and their chance of developing heart problems plummeted. The results, published in the New England Journal of Medicine, have revealed a number of questions about how to prevent heart attacks. Is exercise and a low-fat diet enough, or should large swathes of the population be prescribed preventative medication? Nature News gets to the heart of the matter.
Mini heart attack best treated like the big one

People who show up at a hospital with mild heart attack symptoms, but only ambiguous scores on medical tests, might still warrant emergency treatment, according to research presented at a meeting of the American Heart Association.
Genetic study undermines case for CRP as cause of vascular disease

Copenhagen, Denmark- Is C-reactive protein (CRP) a promoter of cardiovascular disease or simply a marker of increased cardiovascular risk? Probably the latter, according to the latest study to address the question, in which four gene variants tied to sharply increased CRP levels were shown not to be associated with an elevated CV-event risk
How to stop a new type of heart attack

PACEMAKERS are supposed to protect people from heart attacks. But to do that they have to provide digital as well as biological security.
Earlier this year, a team led by William Maisel at Harvard Medical School demonstrated how a commercial radio transmitter could be used to modify wireless communications from a pacemaker (New Scientist, 22 March, p 23). Doctors normally use these signals to monitor and adjust the implanted device, but a malicious hacker could reprogram the pacemaker to give its wearer damaging shocks, or run down its batteries
Vitamin D May Help Prevent Heart Attacks

A team of clinical trial specialists and consumer advocates has concluded that blood substitutes increase death rates by 30% and nearly triple the risk of heart attacks. Not everyone buys the findings, however, and clinical trials in the field continue.
