This paper provides a comprehensive overview of heart attacks, explaining how blockages in the coronary arteries caused by plaque buildup lead to reduced or stopped blood supply to the heart muscle. It outlines both controllable and uncontrollable risk factors, describes the warning signs identified by the American Heart Association, and details emergency response measures including CPR and aspirin use. The paper also reviews diagnostic tools such as ECGs and blood tests, and covers treatment procedures including balloon angioplasty, stent placement, and bypass surgery. Finally, it addresses in-hospital care and long-term lifestyle adjustments recommended for heart attack survivors.
A heart attack occurs when the blood supply to part of the heart muscle is severely reduced or stopped. This happens when one or more of the coronary arteries supplying blood to the heart muscle becomes blocked. The blockage is usually caused by the buildup of plaque that bursts, tears, or ruptures, creating a site where a blood clot forms and obstructs the artery, leading to a heart attack. Coronary artery disease causes approximately 1.5 million heart attacks each year.
There are many causes of heart disease; some are controllable and some are not. Uncontrollable risk factors include male gender, older age, family history of heart disease, post-menopausal status, and race — Blacks and Mexican-Americans face larger risks for heart disease than whites. Risk factors that can be controlled include smoking, inappropriate cholesterol levels, uncontrolled hypertension, physical inactivity, obesity, uncontrolled diabetes, and uncontrolled stress and anger.
Most individuals think of heart attacks as sudden and intense, but the majority of heart attacks start slowly, with only mild pain or discomfort. In fact, some people affected are not sure what is wrong and delay getting medical attention. According to the American Heart Association, the symptoms of a heart attack include the following:
Chest discomfort. Most heart attacks involve discomfort in the center of the chest that lasts more than a few minutes, or that goes away and comes back. It can feel like uncomfortable pressure, squeezing, fullness, or pain.
Discomfort in other areas of the upper body. Symptoms can include pain or discomfort in one or both arms, the back, neck, jaw, or stomach.
Shortness of breath. This feeling often comes along with chest discomfort, but it can occur before the chest discomfort appears.
Other signs. These may include breaking out in a cold sweat, nausea, or lightheadedness.
