A heart attack, also known as a myocardial infarction, occurs when a coronary artery that supplies blood and oxygen to the heart becomes blocked. Heart attacks are a leading cause of death but are not inevitable. Here are some strategies to help you protect your heart and prevent heart disease by following a heart-healthy lifestyle.
What Are the Symptoms of Heart Attack?
The blockage of the blood and oxygen to the heart is typically caused by the buildup of fatty deposits, cholesterol, and other substances that form plaques within the artery walls. Over time, these plaques can become unstable and rupture, forming a blood clot.When a blood clot completely blocks the artery, it prevents blood flow to a section of the heart muscle. The affected heart muscle tissue dies without an adequate supply of oxygen and nutrients.
