Imagine coronary arteries choked with a bumpy layer of atherosclerotic plaque. Preclinical studies suggest that this treatment could reduce atherosclerotic plaque burden, and thereby decrease the risk of a secondary cardiovascular event. Their research indicates stress causes vessels already choked with atherosclerotic plaque to narrow even more, thereby increasing a person's chance of suffering dangerous ischemia--bouts of reduced blood flow to the heart that can lead to a heart attack. |
