Johns Hopkins Scientists Alter Fat Metabolism in Animals to Prevent Most Common Type of Heart Disease

Working with mice and rabbits, Johns Hopkins scientists have found a way to block abnormal cholesterol production, transport and breakdown, successfully preventing the development of atherosclerosis, the main cause of heart attacks and strokes and the number-one cause of death among humans. The condition develops when fat builds inside blood vessels over time and renders them stiff, narrowed and hardened, greatly reducing their ability to feed oxygen-rich blood to the heart muscle and the brain.

A report on the research appears in the April 1 issue of Annals of Internal Medicine.

Exercise Training Improves Health Outcomes of Women with Heart Disease More Than of Men

In the largest study to ever investigate the effects of exercise training in patients with heart failure, exercise training reduced the risk for subsequent all-cause mortality or all-cause hospitalization in women by 26 percent, compared with 10 percent in men.
