Abstract

To investigate the effect of Kawasaki syndrome on left ventricular function, we studied 52 patients with Kawasaki syndrome at initial visit and after 3 months (36 patients). Using Pulsed Doppler echocardiogram,we obtained aortic velocity (peak and mean), acceleration time(AT),ejection time(ET), ratio of AT to ET(AT/ET), acceleration (peak and mean) and velocity time integral and mitral velocity of E and A waves(peak and mean) and velocity time integral. Mitral time for peak velocity time integral. Mitral time for peak velocity was significantly prolonged in Kawasaki syndrome,being a mean(+/-SD) of 66.2(+/-14) msec in the control group, 79.2(+/-13)msec at initial vist(p<0.05) and 79.4(+/-13) msec after 3 months (p<0.05). Aortic peak acceleration was significantly decreased in Kawasaki syndrome being a mean(+/-SD) of 2590(+/-785) cm/sec2 after 3 months (P<0.05).Aortic mean acceleration was also significantly decreased in Kawasaki syndrome being a mean(+/-SD) of 1575( +/-542)cm/sec2 in the control group, 1198(+/-351)cm/sec2at initial visit(p<0.05)and 1124 +/-275cm/sec2 after 3 months(p<0.01). Aortic acceleration time was significantly prolonged in Kawasaki svndrome being a mean(+/-SD) of 62(+/-13) msec in the control group, 72(+/-13) msec at initial visit(p<0.05) and 76(+/-16) msec in the control group, 72(+/-13) msec at initial visit(p<0.05) and 76(+/-16) msec after 3 months (p<0.01). We conclude that early abnormalities of left ventricular function, as assessed by echocardiograpy,gencrally persist after 3 months of onset.
