what does it mean if the middle of your heart has some thickening
HCM is the second most common form of cardiomyopathy. If you have HCM, it means that the walls of your heart are thicker than they should be. Some thickening is normal for healthy people who exercise or who play competitive sports. But with HCM, the thickening becomes extreme. In time, the thickening of the heart muscle can cause the heart to get bigger, or enlarge.
