Prinzmetal angina

Prinz·met·al an·gi·na

(prinz'met-ăl),
a form of angina pectoris, characterized by pain that is not precipitated by cardiac work, is of longer duration, is usually more severe, and is associated with unusual electrocardiographic manifestations including elevated ST segments in leads that usually show such elevation during acute coronary thrombosis occurring at night in bed.

(prints'met-ăl an'ji-nă)
A form of angina pectoris that is characterized by pain that is not precipitated by cardiac work, is of longer duration, is usually more severe, and is associated with unusual electrocardiographic manifestations including elevated ST segments in leads that are ordinarily depressed in typical angina, and usually without reciprocal ST changes; occurring at night in bed in electrocardiographic leads in which ST segment depression occurs in typical angina. Treatment includes nitroglycerine or beta-blocker medications.
Synonym(s): angina inversa, variant angina pectoris, variant angina.

Prinzmetal angina's prevalence changes for geography, the frequency in Western population being much smaller than in the Eastern one, especially in Asia; also for sex, which is rather more common in men.
Prinzmetal angina has a daily circadian rhythm with onset at rest, from midnight until early morning (Prinzmetal 1959) but it may be induced by exercise shortly after awakening.
The most common arrhythmia in patients with Prinzmetal angina is ventricular tachycardia, which initially occurs in 2/3 of the patients during anginal episodes, and 1/3 in resolution periods.
Although older people are more likely to develop Prinzmetal angina, smoking has a stronger effect in determining the occurrence of pathology in the young population.
Spontaneous ischemic episodes are often preceded by a decrease of the vagal activity, followed by an increase of catecholamines in the coronary level, to suggest that Prinzmetal angina is not necessarily induced by any vagal activity (Hung MJ 2014).
The research to determine genetic mutations or polymorphisms in the pathogenesis of Prinzmetal angina is inconsistent.
The diagnosis of Prinzmetal angina is complex and cannot be determined only by symptoms, electrocardiogram or stress testing.
Coronary angiography with provocative testing is the only reliable method for the diagnosis of Prinzmetal angina. In patients with ST-segment elevation during anginal episodes, but with a normal coronary angiography, it is not necessary to use provocative testing for a positive diagnosis.
The early initiation of treatment in Prinzmetal angina is important in preventing complications such as myocardial infarction, arrhythmias or sudden death.
He had previously been diagnosed with arterial hypertension and Prinzmetal angina but was not receiving any regular medications.
Our patient had a medical history of Prinzmetal angina, which was successfully treated with calcium channel blockers.
Rajesh Kumar suffered an attack of Prinzmetal angina and collapsed and died in the garage of his home last December.
