But reducing their sedentary time by just an hour a day appears to lower the risk of cardiovascular diseases...

In studies using mice, they discovered a previously unknown mechanism between the brain, bone marrow, and blood vessels that appears to protect against the development of atherosclerosis, or hardening of the arteries—but only when...

New tool that uses DNA sequencing could improve transplant outcomes and save lives Researchers have developed a simple blood test that can detect when a newly transplanted lung is being rejected by a patient, even when no outward signs of the rejection are evident. The test could make it possible for doctors to intervene faster to prevent or slow...

African-Americans who smoke appear to be at greater risk for peripheral artery disease, or PAD, new research has found. Additionally, the findings suggest that smoking intensity – how many cigarettes a day and for how many years – also affects the likelihood of getting the disease. PAD affects 8 to 12 million people in the United States and 202...

Findings reveal tripling of blood levels of TMAO from red meat diet, but dietary effects can be reversed Researchers have identified another reason to limit red meat consumption: high levels of a gut-generated chemical called trimethylamine N-oxide (TMAO), that also is linked to heart disease. Scientists found that people who eat a diet rich in red...

Treatment of sleep disorder might help improve blood pressure control in this high-risk group African-Americans with moderate or severe sleep apnea are twice as likely to have hard-to-control high blood pressure when their sleep apnea goes untreated, according to a new study funded mainly by the National Heart, Lung, and Blood Institute (NHLBI)...
