How do heart attacks happen naturally?
A heart attack is when part of the heart muscle is cut off from oxygen. If the oxygen isn’t restored soon, a heart attack occurs. The blood in your coronary arteries carries oxygen to the heart muscle. Most heart attacks occur when a blockage slows or stops blood flow.

Why do healthy people have heart attacks?
Seemingly healthy people are “suddenly” having heart attacks because, as it turns out, their arteries are not perfectly healthy and they don’t know it. With the proper noninvasive tests, these diseased arteries would have been identified, and the heart attacks wouldn’t have happened.
