Dallas heart study researchers find no link between Lp(a), calcium

The latest findings from the historic Dallas Heart Study have ruled out one of the most prominent explanations of why elevated levels of a fat-carrying protein called "lipoprotein(a)" lead to increased risks for heart attacks among whites but not among African-Americans.

Tumour Necrosis Factor alpha (TNF-alpha) blocking agents cause skin disease

Members of the second most important family of drugs used to treat rheumatoid arthritis can cause serious dermatological conditions in a quarter of patients under treatment, reveals a study published in the journal Arthritis Research and Therapy.

Airway inflammation boosts infarction damage

Epidemiological studies show that the incidence of cardiovascular disease (CVD) complications are increased in long standing cases of asthma. Historically, the complications are often attributed to the chronic drug therapy used to treat asthma.

Study of Anoxia could yield better anesthetics, stroke/heart attack recovery

For a human, mere minutes without oxygen (called anoxia) resulting from cardiac arrest, cerebral stroke or being trapped under water can lead to profound tissue damage and even death. However a Western painted turtle can survive anoxia for months without apparent tissue damage. Why, and how?

Cranberry juice may help protect against heart disease

Protection against a wide variety of diseases is among the many benefits of a diet high in whole fruits and vegetables. Cranberries over the years have been identified with preventing or ameliorating urinary tract infections and playing a positive role gum disease, ulcers and even cancer.

Simvastatin linked to protection against endothelial dysfunction in diabetic rats

Almost two years ago, the diabetes arm of the Heart Protection Study, the largest-ever study using a cholesterol-lowering medication, found that diabetics who took a daily dose of the statin drug simvastatin over five years reduced the risk of a first nonlethal heart attack by 37 percent and risk of a first nonfatal or fatal stroke by 24 percent, regardless of their cholesterol or glucose levels.

Discovery could lead to new drug targets for heart disease

Mice with glowing green hearts have yielded the latest clue in the search for molecules involved in structural heart disease. Vanderbilt University Medical Center investigators found that blocking the activity of a single protein, called CaM kinase, in the mouse heart protects against the damaging effects of a heart attack.

Optical coherence tomography (OCT) can successfully identify the characteristics of coronary plaques

A catheter-based imaging technology called optical coherence tomography (OCT) can successfully identify the characteristics of coronary plaques in patients with various cardiac symptoms. The report from researchers at Massachusetts General Hospital (MGH) will appear in the journal Circulation.

Pcsk9 gene - new target for cholesterol-lowering drugs

Mice lacking a key protein involved in cholesterol regulation have low-density lipoprotein, or "bad" cholesterol, levels more than 50 percent lower than normal mice, and researchers suggest that inhibiting the same protein in humans could lead to new cholesterol-lowering drugs.

Heart attacks can be triggered by physical exertion and emotional stress

Philip Strike and Andrew Steptoe of University College London, in a review published in the current issue of Psychosomatic Medicine, of dozens of studies done between 1970 and 2004 have come up with compelling evidence that indicates that people with a history of heart disease, can trigger heart attacks, some of them fatal, by physical exertion and emotional stress.

Treatment of cardiac lesions without anaesthesic

Navarre University Hospital has introduced a novel technique for the treatment of congenital heart defects and involving the percutaneous closure of the patent foramen ovale (PFO) with monitoring through intracavernous ecography.

Physical exertion and emotional stress can trigger heart attacks in people with a history of heart disease

Authors Philip Strike and Andrew Steptoe of University College London point out that the triggers for heart attacks may be quite different from the factors that lead to development of coronary heart disease over the long term, such as cigarette smoking, lack of exercise, work stress, social isolation, anxiety and depression.

Calls to regionalize the care of patients with heart attacks are premature

Calls to regionalize the care of patients with heart attacks are premature, and do not account for potential unintended consequences, according to a commentary by Yale researchers published in the Journal of the American Medical Association (JAMA).

Rapid rise in obesity may reverse life expectancy trend

It's been assumed that U.S. life expectancy would rise indefinitely, but a new data analysis, published as a special report in the March 17 New England Journal of Medicine, suggests that this trend is about to reverse itself -- due to the rapid rise in obesity, especially among children.

Ongoing specialist care can improve heart attack survival

When a good network of care involving access to specialists and family physicians is established, it can significantly improve the number of lives saved from heart disease, especially in rural areas, according to a University of Alberta two-year study.

Link between C-reactive protein, heart disease and stroke

The cells that line the arteries are able to produce C-reactive protein, according to a study funded by the National Institutes of Health and published in the April issue of American Journal of Pathology.

Vitamin E may increase heart attack risk - does not prevent cancer

A study by Canadian researchers Eva Lonn, M.D., of the Population Health Research Institute and McMaster University, Hamilton Health Sciences Corporation, Hamilton, Ontario, Canada, and colleagues, has found from examining experimental and epidemiological data, that patients who took vitamin E supplements for 7 years did not significantly reduce their risk of cancer or cardiovascular events and some in fact had an increased risk of heart failure.
