Angina, also known as angina pectoris, is chest pain or pressure, usually caused by insufficient blood flow to the heart muscle (myocardium). [2] It is most commonly a symptom of coronary artery disease. [2] Angina is typically the result of partial obstruction or spasm of the arteries that supply blood to the heart muscle. [3]
Angina comes from the latin angere, which means to strangle, and pectoris comes from pectus, meaning chest—so angina pectoris loosely translates to “strangling of the chest”, which actually makes a lot of sense, because angina pectoris is caused by reduced blood flow which causes ischemia to the heart muscle, or lack of oxygen to the ...
Variant angina is caused by vasospasm, a narrowing of the coronary arteries due to contraction of the heart's smooth muscle tissue in the vessel walls. [3] In comparison, stable angina is caused by the permanent occlusion of these vessels by atherosclerosis, which is the buildup of fatty plaque and hardening of the arteries. [4]
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 ...
Atherosclerosis is caused by damage to your arteries that triggers a cascade of events that leads to plaque build-up. Once your endothelium is damaged, your body produces inflammation as a defense ...
[3] [20] A following study further distinguished this angina from classical angina pectoris due to the fact that the results showed that the patients with chest pain due to coronary vasospasm lacked evidence of atherosclerosis on cardiac catheterization. [3] [20] Angina due to coronary vasospasm is also known as variant angina. [20]
Stress can be understood as the body’s response to big life events and perceived threats or danger. There are various types of stress, a wide range of symptoms, and numerous resulting impacts on ...
