Abnormal heart scans predict higher risks for African-Americans and Hispanics

SPECT imaging scans show that abnormalities in blood flow to the muscle of the heart indicate higher cardiovascular disease risk in African-Americans and Hispanics than similar abnormalities in white patients, according to a new study (PDF) in the May 3, 2005, issue of the Journal of the American College of Cardiology.

Research suggests potential new strategies for fighting age-related vascular disease

Declining function of cells that help repair the inner lining of blood vessels, known as endothelial progenitor cells, rather than a dwindling supply of the cells, may underlie the increased risk of atherosclerosis and other vascular diseases as people grow older, according to a new study (PDF) in the May 3, 2005, issue of the Journal of the American College of Cardiology.

MDCT highly accurate for diagnosing coronary artery disease in patients with zero to moderate coronary calcification

In patients with no or moderate coronary calcification, 16-slice MDCT allows the reliable detection of coronary artery stenosis with high diagnostic accuracy, say researchers from Tuebingen University Hospital in Germany. Coronary artery stenosis is the narrowing of coronary arteries due to the build-up of calcified plaques.

Critical lock and key mechanism found for the assembly of tumor blood vessels

A critical lock and key mechanism that allows the final step in the completion of new blood vessel formation has been identified by a University of California, San Diego (UCSD) School of Medicine team in research that promises to lead to a new way to halt tumor growth by cutting off the tumor blood supply.

Scientists dramatically slow organ transplant rejection

That's the promising implication of an animal study carried out by researchers at the University of Alabama at Birmingham (UAB) and the University of Florida (UF) published in today's (May 2) issue of Proceedings of the National Academy of Sciences.

Severely obese children have lipoprotein profiles that signal early risk of cardiovascular disease and the metabolic syndrome

"The message is urgent about the importance of prevention of cardiovascular disease in childhood. Lifestyle modification with appropriate diet and exercise can reduce cardiovascular risk in children," said lead author Daniel L. Preud'Homme, M.D., associate professor of medicine at the Wright State University School of Medicine and director of the lipid clinic at The Children's Medical Center, both in Dayton, Ohio.

Fiber supplements may lower cardiovascular risk in type 2 diabetics

Fiber supplements lower "bad" low-density lipoprotein (LDL) cholesterol and increase "good" high-density lipoprotein (HDL) cholesterol in people with type 2 diabetes, according to a study presented at the American Heart Association's Sixth Annual Conference on Arteriosclerosis, Thrombosis and Vascular Biology.

Research may re-define management of heart failure in diabetes

Control of oxidised copper levels in the body may be as important as lowering blood glucose levels in preventing cardiovascular complications in diabetes mellitus, according to New Zealand researchers.

Trial to evaluate modern stent technologies over balloon angioplasty for peripheral arterial disease

The first patient undergoes treatment today in a new prospective randomised trial, called the SUPER Study, to compare stenting with balloon angioplasty in patients with superficial femoral artery (SFA) occlusions caused by peripheral artery disease (PAD).

Increased risk associated with combining carotid artery, coronary artery surgeries

Among patients undergoing evaluation for coronary artery bypass surgery, stroke neurologists are frequently consulted when the patient also has severe carotid artery stenosis (blockage of an artery that supplies blood to the brain).

Angiogenesis : Blocking tumor growth and treating infarction - a new target

Our tissues are able to form new blood vessels throughout life. This mechanism, which is called angiogenesis, is essential notably in the case of myocardial infarction, stroke and limb ischemia. The very same mechanism, however, keeps tumors supplied with nutrients and oxygen thus enabling them to continue growing.

Report reveals urgent need to improve physical health of people with Schizophrenia

People with schizophrenia often die prematurely. However researchers from the University of Glasgow and NHS Greater Glasgow assert that much of the excess mortality of schizophrenia is preventable through lifestyle changes and the treatment of common diseases.

Bypass surgery does not carry long term neurological effects

In a wide retrospective review of the effects of coronary artery bypass grafting (CABG) on memory and other brain functions a team of U.S. researchers has concluded that, while there may be transient short-term effects, the procedure itself probably does not cause late or permanent neurological effects.

Evidence suggests bypass surgery free of long-term brain effects

A broad retrospective review of the effects of coronary artery bypass grafting (CABG) on memory and other brain functions concludes that, while there may be transient short-term effects, the procedure itself probably does not cause late or permanent neurological effects.

Drinking wine or beer has same result: higher blood pressure

Whether the drink of choice is a frosty beer or a full-bodied red wine, the effect is the same – higher blood pressure, according to research reported in Hypertension: Journal of the American Heart Association.

Cancer patients may one day benefit from treatment with mixtures of customized antibodies

In a study published recently in the Proceedings of the National Academy of Sciences (USA), a team of Weizmann Institute scientists have demonstrated how the right combination might form a web that destroys the cancer cell's communication network, ultimately demobilizing the cell.
