blood flow

Biochemists have identified a mixed bag of five key proteins out of thousands secreted into blood draining from the heart's blood vessels that may together or in certain quantities form the basis of a far more accurate early warning test than currently in use of impending heart attack in people with severely reduced blood flow, or ischemia.

Results of a study on an embolic protection system during carotid stenting that uses a novel blood flow reversal system were reported during the 20th annual Transcatheter Cardiovascular Therapeutics scientific symposium.

Even occasional cigarette smoking can impair the functioning of your arteries, according to a new University of Georgia study that used ultrasound to measure how the arteries of young, healthy adults respond to changes in blood flow.

Machines on cell surfaces, mechanical and lifeless as bed springs, protect blood vessels by responding to blood flow force, according to research published today in the Journal of Cell Biology.

By sensing and reacting to force, such machines interfere with inflammatory pathways central to atherosclerosis, the leading cause of heart attack and stroke.

The next set of studies will seek to "tweak" the process with the goal of designing a new class of therapies.

Nearly two out of three patients have one or more precipitating factors that may contribute to hospital admissions nationwide for heart failure, according to a new study.

Pneumonia, irregular heart beats and obstructed blood flow to the heart are the most frequent factors. The findings may help cardiologists better understand the factors that contribute to hospitalizations for heart failure and may help improve management of the disease.

Researchers induced stress in 148 patients with coronary artery disease by asking them to speak in public. Those with a particular gene variation were three times more likely to experience dangerous decreases in blood flow to the heart during stress.

Prostate tumors grew more quickly in mice who exercised than in those who did not, leading to speculation that exercise may increase blood flow to tumors, according to a new study.

The researchers want to caution men against interpreting these findings as an endorsement for not exercising for fear of getting or exacerbating cancer.

Male smokers who consume more magnesium appear to have a lower risk for cerebral infarction, a type of stroke that occurs when blood flow to the brain is blocked, according to a new report.
