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]
Vasospasm is the major cause of Prinzmetal's angina. Cerebral vasospasm may arise in the context of subarachnoid hemorrhage as symptomatic vasospasm (or delayed cerebral ischemia ), where it is a major contributor to post-operative stroke and mortality.
Coronary vasospasm refers to when a coronary artery suddenly undergoes either complete or sub-total temporary occlusion. [1]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]
It is also regarded as responsible for Prinzmetal's angina. Receptors that mediate TXA 2 actions are thromboxane A 2 receptors. The human TXA 2 receptor (TP) is a typical G protein-coupled receptor (GPCR) with seven transmembrane segments. In humans, two TP receptor splice variants – TPα and TPβ – have so far been cloned.
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 ...
Prinzmetal authored at least 165 publications over the course of his career. [1] The main focus of his research was hypertension, and he named and described Prinzmetal's angina, a variant of classical angina that occurs at rest. [2] During the Second World War, he focused his research on shock caused by muscle trauma and
Joe Alwyn has moved on from his relationship with Taylor Swift — and he believes everyone else should do the same.. In a new interview with The Guardian, the actor, 33, responded to the outlet's ...
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]
