Red wine lovers, take heart: More evidence points to the drink's cardiac heath benefits

COLUMBUS, Ohio New research on rat heart cells suggests that a well-known antioxidant found in red wine, called resveratrol, may benefit heart tissue by limiting the effects of a condition called cardiac fibrosis.

Diseases such as hypertension and heart failure can cause fibrosis, a hardening or stiffening of the heart tissue. This condition arises when heart cells called cardiac fibroblasts are activated. These cells secrete collagen, a protein that provides structural support for the heart.

Overactive cardiac fibroblasts cause fibrosis of the heart tissue, which then loses its ability to efficiently pump blood, said Joshua Bomser, a study co-author and an assistant professor of human nutrition at Ohio State University.

While resveratrol is already known for helping to prevent blood clots and also possibly reducing cholesterol, this is the first time that scientists have studied the compound's direct effects on these heart cells.

The study currently appears online on the American Journal of Physiology Heart and Circulatory Physiology website. Bomser worked with a team of researchers from the Northeastern Ohio Universities College of Medicine, led by J. Gary Meszaros.

While the researchers can't say how much resveratrol is needed to be beneficial, previous studies suggest that drinking red wine in moderation one or two five-ounce glasses a day may offer protective effects. Nearly all dark red wines merlot, cabernet, zinfandel, shiraz and pinot noir contain resveratrol.

In the current study, treating rat cardiac fibroblasts cells with resveratrol prevented the actions of a potent hormone called angiotensin II. In the case of hypertension and heart failure, angiotensin II is produced at a high level, which is the body's way of trying to repair damage to the heart and to increase blood pressure.

But the plan usually backfires, as the hormone causes cardiac fib
