Ischemic cardiomyopathy is a type of cardiomyopathy caused by a narrowing of the coronary arteries which supply blood to the heart. [4] Typically, patients with ischemic cardiomyopathy have a history of acute myocardial infarction, [5] however, it may occur in patients with coronary artery disease, but without a past history of acute myocardial infarction.
Information card published by the National Heart, Lung, and Blood Institute urging people with symptoms of angina to call the emergency medical services.. Because of the relationship between the duration of myocardial ischemia and the extent of damage to heart muscle, public health services encourage people experiencing possible acute coronary syndrome symptoms or those around them to ...
Acute coronary syndrome (ACS) is a syndrome due to decreased blood flow in the coronary arteries such that part of the heart muscle is unable to function properly or dies. [1] The most common symptom is centrally located pressure-like chest pain, often radiating to the left shoulder [2] or angle of the jaw, and associated with nausea and sweating.
A normal ECG does not rule out acute myocardial infarction. Mistakes in interpretation are relatively common, and the failure to identify high risk features has a negative effect on the quality of patient care. [12] It should be determined if a person is at high risk for myocardial infarction before conducting imaging tests to make a diagnosis ...
If blood flow through the coronary arteries is stopped completely, cardiac muscle cells may die, known as a myocardial infarction, or heart attack. [9] Coronary artery disease (CAD) is the most common cause of coronary ischemia. [7] Coronary ischemia and coronary artery disease are contributors to the development of heart failure over time. [10]
Acute decompensated heart failure (ADHF) is a sudden worsening of the signs and symptoms of heart failure, which typically includes difficulty breathing , leg or feet swelling, and fatigue. [1] ADHF is a common and potentially serious cause of acute respiratory distress .
Unstable angina is a type of angina pectoris [1] that is irregular or more easily provoked. [2] It is classified as a type of acute coronary syndrome. [3]It can be difficult to distinguish unstable angina from non-ST elevation (non-Q wave) myocardial infarction.
The main cause of angina is coronary artery disease, but can result from other non-atherosclerotic causes such as anemia and heart failure. Stable angina results if the angina resolves with rest or nitroglycerin, but can progress to unstable angina which is a form of acute coronary syndrome.
