NT-proBNP was associated with a newdevelopment of atrial fibrillation (95% CI: 1,020 – 1,130), newdialysis requirement (95% CI: 1,240 – 1,630), postoperativecerebrovascular event (95% CI: 1,110 – 1,300), low cardiac output(95% CI: 1,140 – 1,310), pneumonia (95% CI: 1,070 – 1,250), andmediastinitis (95% CI: 1,050 – 1,440). The gene discussed is NPPB; the disease is atrial fibrillation.
