Abstract

To investigate the effect of Kawasaki disease on left ventricular function, we studied 92 patients with Kawasaki disease at initial visit, after 3 months (78 patients) and after 1 year (9 patients). Using serial M-mode echocardiogram, we obtained LVD(d) (left ventricular internal dimension at end diastole), LVD(s)(left ventricular internal dimension at end systole), FS (fractional shortening), ET (ejection time), VmCF (mean velocity of circumferential fiber shortening), PWTD (posterior wall thickness at end diastole), PWTS (posterior wall thickness at end systole) and peak systolic wall stress. Fractional shortening was significantly decreased in Kawasaki disease, being a mean (+/-SD) of 38.9 (+/-8.2)% in the control group, 33.8 (+/-7.8) at initial visit (P<0.05), 34.8(+/-7.0) after 3 months (P<0.05), and 33.8 (+/-3.4) after 1 year (P<0.05). Rate corrected VmCF was significantly decreased in Kawasaki disease, being a mean (+/-SD) of 1.25 (+/-0.28) circ/sec in the control group, 1.05 (+/-0.28) at initial visit (P<0.01), 1.10 (+/-0.25) after 3 months (P<0.05), 1.08 (+/-0.15) after 1 year (P<0.05). Peak systolic wall stress was significantly increased in Kawasaki disease, 51.7 (+/-16.6) gm/cm2 in the control group, 64.9 (+/-20.7) at initial visit (P<0.05), 63.2 (+/-18.3) after 3 months (P<0.05), 76.6 (+/-17.3) after 1 year (P<0.01). Peak systolic wall stress adjusted, rate corrected mean velocity of circumferential fiber shortening was significantly decreased only at initial visit. We concluded that abnormalities of left ventricular function, as assessed by M-mode echocardiography, generally persist after 1 year.
