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]
Studies reveal stress induces inflammation within the arteries and disrupts endothelial function (your blood vessels’ ability to regulate blood flow) by increasing heart rate and blood pressure ...
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]
Chronic inflammation Various markers of low-grade chronic inflammation have been found in cases of coronary vasospasm. [14] [15] In addition to this, one of the risk factors for coronary vasospasm is smoking. [9] [10] Chronic inflammation due to smoking has been shown to be damaging to endothelial cell function. [16] Oxidative Stress
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 ...
Video explanation. Author: Tanner Marshall, MS Editor: Rishi Desai, MD, MPH 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 ...
Due to its presentation, Tietze syndrome can be misdiagnosed as a number of conditions, including myocardial infarction (heart attack), angina pectoris, and neoplasms. [6] [8] [10] Costochondritis is most commonly confused with Tietze syndrome, as they have similar symptoms and can both affect the costochondral and sternocostal joints ...
ACS should be distinguished from stable angina, which develops during physical activity or stress and resolves at rest. In contrast with stable angina, unstable angina occurs suddenly, often at rest or with minimal exertion, or at lesser degrees of exertion than the individual's previous angina ("crescendo angina"). New-onset angina is also ...
