A comparative study of two—dimensional echocardiography and systolic time intervals in the evaluation of left ventricular function in coronary heart disease

Abstract

In this study, we attempt to analyze the data of two-dimensional echocardiography and systolic time intervals in 21 patients with documented coronary artery disease. No dysfunction of ventricular wall motion was found in any of the 4 patients with angina pectoris at rest. Abnormal segmental ventricular wall motions were observed in the other 17 patients with myocardial infarction. The apical region was involved in 13 cases and the dyskinesis accounted for 33.9 per cent of the total number of abnormal segments. Left ventricular wall motion index was closely correlated with systolic time intervals, including PEP, LVET and PEP/LVET. The correlation coefficients were-0.72, 0.85 and-0.80 respectively. It has been suggested that left ventricular wall motion index is a valuable one for evaluating left ventricular function and that systolic time intervals can reflect indirectly the presence and severity of abnormal ventricular segmental motion in patients with myocardial infarction.
