Study identifies new mechanism linking activation of key heart enzyme and oxidative stress

A study, led by University of Iowa researchers, reveals a new dimension for a key heart enzyme and sheds light on an important biological pathway involved in cell death in heart disease.

Breakthrough compound could lead to new class of antihypertensive drugs

University of Florida researchers have identified a drug compound that dramatically lowers blood pressure, improves heart function and - in a remarkable finding - prevents damage to the heart and kidneys in rats with persistent hypertension

New findings on vitamin E and cataracts in women

A new analysis of the Women's Health Study (WHS) found that women who took Vitamin E supplements had rates of cataract development comparable to women who did not take such supplements.

FDA approves coronary artery plaque imaging device

The U.S. Food and Drug Administration has cleared for marketing a device that a doctor can use to see inside a blood vessel to assess the fat content of the plaque which builds up on the wall of the coronary arteries.

Abmormal behaviour of osteoglycin gene linked to heart and kidney problems

A gene that can cause the heart to become enlarged, greatly increasing the risk of heart attacks and heart failure, is identified today in a new study.

Do patients have equal access to coronary angiography?

Seven in ten patients who have suspected angina are not given appropriate testing and are more likely to suffer from serious heart problems as a result, according to a study published on bmj.com (25 April).

Former Bristol-Myers Squibb exec indicted for lying about Plavix blood-thinning drug

The Department of Justice announced today that the former senior vice president of Bristol-Myers Squibb Company (BMS), Andrew Bodnar, was indicted for his role in lying to the federal government about a patent deal involving the popular blood-thinning drug, Plavix, used by heart attack, stroke and other patients.

Breakthrough in stem cell research

Dutch researchers at University Medical Center Utrecht and the Hubrecht Institute have succeeded in growing large numbers of stem cells from adult human hearts into new heart muscle cells.

Drug-releasing stent shows promise for improving outcomes in patients with coronary artery disease

For patients who underwent angioplasty to open narrowed coronary arteries, the use of stents releasing the drug everolimus reduced the rate of renarrowing of the arteries and significantly reduced the risk of major cardiac events, compared to the widely-used paclitaxel-releasing stents, according to a study in the April 23/30 issue of JAMA, the Journal of the American Medical Association.

Discovery of new way to prevent cardiac fibrosis

In a study that points to a new strategy for preventing or possibly reversing fibrosis - the scarring that can lead to organ and tissue damage - researchers at the University of California, San Diego School of Medicine have determined that a molecule called Epac (Exchange protein activated by cAMP1), plays a key role in integrating the body’s pro- and anti-fibrotic response.

Simple saliva test gives speedy heart attack diagnosis

Scientists in the U.S. have developed a simple saliva test which will quickly show if a person is having or about to have a heart attack.

Patients arriving at hospitals in daytime hours get faster, better care compared to off hours

Patients hospitalized with heart attacks tend to get faster and more comprehensive care if they arrive during daytime hours, according to a report in Circulation: Journal of the American Heart Association.

A genetic variation mimics effect of heart failure medications - may explain why beta-blockers do not work for all patients

A genetic variation, found predominantly in African Americans, protects some people with heart failure, enabling them to live longer than expected. That's the conclusion of a research team led by investigators at the University of Maryland School of Medicine in Baltimore and the Washington University School of Medicine in St. Louis.

Heparin versus placebo for acute coronary syndromes

Compared with those on placebos, giving heparin to people who have heart conditions like unstable angina and some forms of heart attack reduces the risk of having another heart attack, concluded a Cochrane Systematic Review.

Frequent migraines linked to women's risk of cardiovascular disease

New research shows women who have weekly migraine are significantly more likely to have a stroke than those with fewer migraines or no migraine at all, but those with lower migraine frequency may face increased risk of heart attacks.

New molecule could be key to anti-heart attack drug

When too many blood platelets stick together in the bloodstream, they form dangerous clots that can clog blood vessels and cause a heart attack. If a clot doesn't get dissolved or rapidly removed, it can cause permanent damage or even death.

Creatinine increase in elderly means increased renal disease, mortality

Even small increases in serum creatinine levels during hospitalization raise the risk of end stage renal disease and mortality of elderly patients over the long term, according to a University of Alabama at Birmingham (UAB) study in the Archives of Internal Medicine.

Drug-treated blood stem cells used to repair heart damage in animal model

Researchers at UT Southwestern Medical Center have for the first time used drug-treated blood stem cells to repair heart damage in an animal model, results that might point to methods for healing injuries from heart attacks or disease.

Profoundly important discovery of differences in heart's precursor cells

Scientists have long thought that the cells that ultimately give rise to the heart all respond to the same cue before turning into the muscle tissue of this vital organ.
