As with our livers, our hearts are unlikely to become damaged by mild, occasional drinking. But the heavy, regular drinking many of us did does indeed damage our hearts. One condition common among heavy drinkers is high blood pressure. This alone can increase the likelihood of a heart attack or stroke. Another condition is alcoholics can develop is known as cardiomyopathy. Cardiomyopathy is a condition in which the heart muscle becomes enlarged and less able to move. This results in poor blood circulation and can cause heart attacks. The heart is a resilient muscle, but like the liver, it can only endure so much abuse before it becomes diseased and unable to function properly.
