Half of heart disease deaths could be prevented

Heart attack, stroke, and other cardiovascular diseases kill nearly three-quarters of a million Americans each year. They are the leading cause of death, accounting for nearly 30% of all deaths in the United States. But according to a new study published online yesterday in the Annals of Internal Medicine, many of these deaths can be prevented. Researchers from the Rollins School of Public Health at Emory University in Atlanta estimated that eliminating five key risk factors for cardiovascular disease — smoking, high cholesterol, high blood pressure, type 2 diabetes, and obesity — would prevent more than half of all U.S. deaths from cardiovascular disease. Realizing that elimination may not be possible, they asked what would happen if, as a nation, we were able to do as well as the residents of the best-performing states. The result was a more modest 10% reduction in cardiovascular disease–related deaths.

More than a stretch: Yoga’s benefits may extend to the heart

Yoga is good for the muscles and the mind. New research suggests that it may also be good for the heart. A review of yoga and cardiovascular disease published in the European Journal of Preventive Cardiology indicates that yoga may help lower heart disease risk as much as conventional exercise, such as brisk walking. It can help people lose weight, lower blood pressure and cholesterol, and ease stress. Each of those changes works to prevent heart disease, and can help people who already have cardiovascular problems.
