Heart Disease

What Causes High Blood Pressure?

Blood pressure is the term used to describe the pressure exerted on the arterial walls as blood flows through them. This pressure is at its highest when the heart contracts and pumps blood through the arteries and is called the systolic pressure.

Review finds blueberry and grape polyphenols may improve vascular health

A review of 37 publications found that grape- and blueberry-derived polyphenols were associated with modest improvements in cardiovascular risk markers, particularly endothelial function. However, most studies were small or short-term, frequently tested concentrated products, and measured biomarkers rather than cardiovascular events.

A common dietary nutrient feeds a gut pathway linked to atrial fibrillation

Researchers linked higher plasma TMAO to prevalent atrial fibrillation in 5,090 people and found that TMAO or choline supplementation accelerated AF onset, progression, atrial remodeling, and electrical dysfunction in mice. Inhibiting gut microbial TMA production lowered circulating TMAO and delayed AF in mice, identifying a potential therapeutic pathway that now requires human testing.
