LEFT-VENTRICULAR DYSKINESIA-SILENT MYOCAR DIAL-ISCHEMIA RELATIONSHIP IN PATIENTS WITH STABLE ANGINA-PECTORIS

A total of 40 patients with Functional Class III-IV stable angina pect oris were examined. Silent myocardial ischemia was detected in 87.5% o f patients by using 24-hour Holter monitoring. A statistically signifi cantly greater amplitude and longer duration of pain episodes were obs erved. The patients underwent exercise echocardiography. Functional ex ercise was performed by frequent-increasing transesophageal cardiac pa cing. The index of local myocardial contractility disturbance was asse ssed and calculated as the product sum of the number of diseases segme nts by the rating coefficient: hypokinesia, 1 score, akinesia, 2 score s, and dyskinesia, 3 scores. There was a statistically higher segmenta l asynchronism in patients having a silent myocardial ischemic episode of more than 15 min. The index of local contractility disturbance in this group of patients was 7.9 +/- 3.2 units. There was a relationship between the duration of silent myocardial ischemia and the presence o f heart failure. It was concluded that the duration of silent myocardi al ischemia might be used as an additional criteria for assessing the severity, prognosis and adequancy of therapy in patients with stable a ngina on effort.
