What is heart disease?
Mention heart disease, and most people picture a heart attack. But the term covers several conditions that can hurt your ticker and keep it from doing its job. These include coronary artery disease, arrhythmia, cardiomyopathy, and heart failure. Learn the warning signs of each and how to react.
