blood flow

Flavanols in some chocolates are showing promise in promoting blood flow to the brain.

University of Florida 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.

Percutaneous coronary intervention may be a reasonable alternative to bypass surgery in patients with blockages in the left main coronary artery, according to a study that found no significant difference in rates of survival when stents and bypass surgery were used to restore blood flow through this critically important artery.

Patients who were treated with stenting were more likely to need a repeat procedure to keep the artery open, however.

Researchers have discovered how diabetes, by driving inflammation and slowing blood flow, dramatically accelerates atherosclerosis, according to research to be published in the March 14 edition of the journal Circulation Research.
