In these reports, 32% (N = 87 patients) had abnormal echocardiograms, 21% (N = 59 patients) had pericarditis or pericardial effusion, 12.8% (N = 35) ventricular dysfunction, 14% (N = 38) coronary aneurysm/dilatation/abnormality, 8% (N = 23) myocarditis, 2,5% (N = 7) valvular dysfunction, 4% (N = 12) abnormal ECG, while 15% (N = 41) of the patients had elevated BNP and troponin levels. Here, NPPB is linked to pericardial effusion.
