Heart Attacks
A Heart Attack (pronounced: /hɑːrt əˈtæk/), also known as a Myocardial Infarction (pronounced: /ˌmaɪoʊˈkɑːrdiəl ɪnˈfɑːrkʃən/), is a serious medical condition that occurs when the blood supply to the heart is suddenly blocked, usually by a blood clot. The term "myocardial infarction" is derived from the Greek words "myo" meaning muscle, "cardia" meaning heart, and "infarction" meaning tissue death due to lack of oxygen.
Causes
Heart attacks are primarily caused by Coronary Artery Disease (CAD), a condition in which the coronary arteries (the major blood vessels that supply the heart with blood) become narrowed due to a build-up of cholesterol and other substances, known as plaque. This process is known as atherosclerosis.
Symptoms
Symptoms of a heart attack can vary, but the most common include chest pain or discomfort, shortness of breath, nausea, and lightheadedness. It's important to seek immediate medical attention if you suspect you're having a heart attack.
Treatment
Treatment for a heart attack usually involves taking medications to dissolve the clot and restore blood flow to the heart. In some cases, a procedure known as angioplasty and stent placement may be performed.
Prevention
Prevention of heart attacks primarily involves lifestyle changes such as eating a healthy diet, exercising regularly, and quitting smoking. Medications may also be prescribed to control conditions that contribute to the development of CAD, such as high blood pressure and high cholesterol.
