This medication decreases blood pressure and makes the heart more efficient, which allows more blood to be pumped from the heart. When Coreg is used for people who develop heart failure or left ventricular dysfunction following a heart attack, it decreases the chance of death by 23 percent and decreases the risk of another heart attack by 40 percent.
