[Prognostic significance of "silent" myocardial ischemia in patients with unstable stenocardia]. 1991

D G Ioseliani, and A N Suanov

A 24-hour ECG monitoring was performed in 30 patients with unstable angina. Ten patients had episodes of transient ST-segment displacement only in the presence of anginal attacks (Group 1), 10 had ST-segment displacement episodes in the presence of both anginal attacks and silent myocardial ischemia (Group 2), and 10 with the displacements concurrent with only silent ischemia (Group 3). The patients from the groups were not significantly different in terms of major clinical, history, and angiographic data. Following an average of 1 year, death and acute myocardial infarction were observed in 1 (10%) and 2 (22.2%) in Group 1; 1 (10%) and 3 (33.3%) in Group 2; and 2 (20%) and 5 (62.5%) patients, respectively. It was concluded that episodes of silent myocardial ischemia are prognostically more hazardous than those of transient hypoxic ECG changes concomitant with anginal attacks.

D011379	Prognosis	A prediction of the probable outcome of a disease based on a individual's condition and the usual course of the disease as seen in similar situations.	Prognostic Factor,Prognostic Factors,Factor, Prognostic,Factors, Prognostic,Prognoses
D003327	Coronary Disease	An imbalance between myocardial functional requirements and the capacity of the CORONARY VESSELS to supply sufficient blood flow. It is a form of MYOCARDIAL ISCHEMIA (insufficient blood supply to the heart muscle) caused by a decreased capacity of the coronary vessels.
