A myocardial infarction ( MI ), commonly known as a heart attack, occurs when blood flow decreases or stops in one of the coronary arteries of the heart, causing infarction (tissue death) to the heart muscle. [ 1] The most common symptom is retrosternal chest pain or discomfort that classically radiates to the left shoulder, arm, or jaw. [ 1]
Coronary ischemia, myocardial ischemia, [ 1] or cardiac ischemia, [ 2] is a medical term for abnormally reduced blood flow in the coronary circulation through the coronary arteries. [ 3] Coronary ischemia is linked to heart disease, and heart attacks. [ 4] Coronary arteries deliver oxygen-rich blood to the heart muscle. [ 5]
Coronary artery disease ( CAD ), also called coronary heart disease ( CHD ), ischemic heart disease ( IHD ), [ 13] myocardial ischemia, [ 14] or simply heart disease, involves the reduction of blood flow to the cardiac muscle due to build-up of atherosclerotic plaque in the arteries of the heart. [ 5][ 6][ 15] It is the most common of the ...
Cardiology. Acute decompensated heart failure ( ADHF) is a sudden worsening of the signs and symptoms of heart failure, which typically includes difficulty breathing ( dyspnea ), leg or feet swelling, and fatigue. [ 1] ADHF is a common and potentially serious cause of acute respiratory distress. The condition is caused by severe congestion of ...
Feb. 13—Sweating, nausea, dizziness and unusual fatigue may not sound like typical heart attack symptoms. However, they are common for women and may occur more often when resting or asleep.
Cardiomyopathy is a group of primary diseases of the heart muscle. [ 1] Early on there may be few or no symptoms. [ 1] As the disease worsens, shortness of breath, feeling tired, and swelling of the legs may occur, due to the onset of heart failure. [ 1] An irregular heart beat and fainting may occur. [ 1]
The most common disease of the muscle is called cardiomyopathy, which is a condition that causes the heart’s muscles to become stiff or weak, Dr. Steinbaum says.
The diagnosis of myocardial infarction requires two out of three components (history, ECG, and enzymes). When damage to the heart occurs, levels of cardiac markers rise over time, which is why blood tests for them are taken over a 24-hour period. Because these enzyme levels are not elevated immediately following a heart attack, patients ...
