Unstable angina (UA) (also "crescendo angina"; this is a form of acute coronary syndrome) is defined as angina pectoris that changes or worsens or begins suddenly at rest. [12] Unstable angina is a medical emergency and requires urgent medical treatment from a doctor. [5] It has at least one of these three features: [13]
Dr. William Heberden is credited with being the first to describe in a 1768 publication the occurrence of chest pain attacks (i.e. angina pectoris) that appeared due to pathologically occluded coronary arteries. These attacks were triggered by exercise or other forms of exertion and relieved by rest and nitroglycerin.
In 1959, Prinzmetal et al. described a type of chest pain resulting from coronary vasospasm, referring to it as a variant form of classical angina pectoris. [2] Consequently, this angina has come to be reported and referred to in the literature as Prinzmetal angina. [3] A subsequent study distinguished this type of angina from classical angina ...
All right, as a quick recap…. Angina pectoris is chest pain caused by reduced blood flow resulting in a lack of oxygen in the heart muscle. There are three types: stable angina, unstable angina, and vasospastic angina. Rest tends to relieve stable angina, but not the other two types, and all three can be treated with nitroglycerin.
Previously, unstable angina was assumed to be angina pectoris caused by disruption of an atherosclerotic plaque with partial thrombosis and possibly embolization or vasospasm leading to myocardial ischemia. [9] [10] However, sensitive troponin assays reveal rise of cardiac troponin in the bloodstream with episodes of even mild myocardial ...
Coronary artery disease (CAD), also called coronary heart disease (CHD), or ischemic heart disease (IHD), [13] is a type of heart disease involving the reduction of blood flow to the cardiac muscle due to a build-up of atheromatous plaque in the arteries of the heart.
In unstable angina, symptoms may appear on rest or on minimal exertion. [6] The symptoms can last longer than those in stable angina, can be resistant to rest or medicine, and can get worse over time. [8] [10] Though ACS is usually associated with coronary thrombosis, it can also be associated with cocaine use. [11]
