A heart attack, also known as a myocardial infarction, happens when the flow of oxygen-rich blood to a section of heart muscle becomes blocked. The heart cannot get oxygen, and the heart muscle begins to die.
Heart attacks are most often caused by a blockage in one of the coronary arteries. This blockage is usually due to a buildup of plaque, which can rupture and form a clot that obstructs blood flow.
Common symptoms of a heart attack include:
Treatment for a heart attack often involves medication, lifestyle changes, and sometimes surgical procedures to restore blood flow to the heart. Immediate treatment is crucial to minimize heart damage.
Preventive measures include maintaining a healthy lifestyle, managing stress, controlling blood pressure and cholesterol levels, and avoiding smoking.
After a heart attack, cardiac rehabilitation plays an essential role in recovery. It includes exercise training, heart-healthy lifestyle education, and counseling to reduce stress and improve heart health.
