Abstract

Objective - In previous echocardiographic studies, a correlation between ejection fraction of the left ventricle and change in the movement of the mitral annular ring was found. In the light of these studies, we planned to investigate the relationship between systolic shortening (SS) and percent ofsystolic shortening (PSS), calculated from the long axis frame in coronaryangiography and left ventricular systolic function. Methods and results - One hundred and thirty-eight patients (40 men and 98women; mean age 58 +/- 10 years) who had been referred for coronary angiography and left ventriculography were included in the study. Ejection fraction (EF) was calculated from left ventriculography obtained from 30 degrees right anterior oblique projection. Distance from the lower border of the ostium of the left coronary artery to the most apical border of the left anterior descending (LAD) artery was measured at end-systole (ES) and end-diastole (ED) using coronary angiography obtained from the same projection. SS as ED-ES and PSS as SS/ED were calculated. Correlation of SS and PSS with EF was calculated (EF = 13.7 + 4.8 x SS, r = 0.91, p < 0.001 and EF = 14.2 + 6.5 x PSS, r = 0.90, p < 0.01). SS < 7 mm(criterion A) and PSS < 6% (criterion B) suggested that left ventricle EF was less than 50%, with a sensitivity, specificity and diagnostic accuracy of 83%, 100%, 95%; 95%, 86% and 88%, respectively. Conclusion - SS and PSS highly significantly correlate with left ventricular EF Therefore, left ventriculography could be omitted in selected patients undergoing coronary angiography if it is not necessary to define the anatomic structure of the left ventricle.
