Prinzmetal’s or Prinzmetal Angina, Variant Angina and Angina Inversa
Spasm of the large- or medium-sized coronary arteries. Individuals with variant angina my have many undocumented episodes prijzmetal symptom-free coronary artery spasm that are associated prinzemtal poor blood flow to portions of the heart and subsequent irregular and potentially serious heart arrhythmias. Some individuals with otherwise typical variant angina may show depressions, rather than elevations in the ST segments of their ECGs during angina pain; they may also show new U waves on ECGs during angina attacks.

Accelerated idioventricular rhythm Catecholaminergic polymorphic Torsades de pointes. Circadian variation of exercise capacity in patients with Prinzmetal’s variant angina: Myron Prinzmetal described a type of angina that differed from the classic cases of Heberden angina in that it commonly occurred in the absence of exercise or exertion. In the absence of angiha ischaemia, other non-cardiac causes of rest pain eg oesophageal spasm need to be considered. Induction of coronary artery spasm by prinametal in patients with variant angina: Sinus bradycardia Sick sinus syndrome Heart block: All fields required unless indicated as optional.
KoronarspasmeKoronar vasospasme. Afflicted individuals should not smoke tobacco products. The only evidence of the presence of totally asymptomatic variant angina would be detection of diagnostic changes on fortuitously conducted ECGs. A comparative study between western and Prinzmetap populations.

An update on spontaneous coronary artery dissection, vasospastic angina and coronary microvascular dysfunction”. ESC sub specialties communities. The pain from variant angina is caused by a spasm in the coronary arteries which supply blood to the heart muscle.
However, individuals commonly develop tolerancei. Coronary microvascular disorders may cause rest angina in patients with normal angiography, which may be distinguished from variant angina by excluding coronary artery spasm with provocative spasm testing.

They are also tested by ECG which may suggest variant angina if it shows elevations in the ST segment or an elevated ST segment plus a widening of the R wave during symptoms vaiante are triggered by a provocative agent e. Ambulatory ECG monitoring may be useful, particularly during a hot phase of the condition, for detecting episodes of ST segment changes as well as associated arrhythmias.
Some key features of variant angina are chest pain that is concurrently associated with elevations in the ST segment on electrocardiography recordings, that often occurs during the late evening or early morning hours in individuals who are at rest, doing non-strenuous activities, or asleep, and that is not associated ce permanent occlusions of their coronary vessels.
