Background:In combination with coronary angiography(CAG), stress echocardiography is the one of the screening methods to detect coronary artery stenosis after percutaneous coronary intervention(PCI), although a non−stress method is desirable from the standpoint of patients burden and time−consuming at out−patient clinic. Toward that end, the potential of non−stress echocardiography with strain rate(SR)analysis was examined. Method:The apical views of the left ventricular wall motion were evaluated by longitudinal two−dimensional(2D)SR to yield four parameters:100− and 200−msec SR values, and minimum SR values between 100− to 200−msec and mean SR values during 100− to 200−msec. Diagnostic accuracy with these parameters for coronary artery stenosis was assessed by determining the coefficients of discriminant function that best predicts an independent diagnosis.Results:The following discriminant function yields 86.39% probability of diagnosis of ≧75% stenosis of coronary artery when discriminant score Z>0:Z=4.91+1.02×(100−msec SR value)+1.23×(200−msec SR value)−0.46×(minimum SR value)+4.83×(mean SR value).Conclusion:Thus, 2D SR analysis of resting apical views with discriminant function is as diagnostically accurate for coronary artery stenosis as stress echocardiography. By non−stress echocardiography in combination with CAG, it is possible enough to follow−up patients more frequently and precisely after PCI.
