In the multivariate analyses, after stepwise adjustment by age and sex in Model I (HR, 9.88; 95% CI, 2.28–42.68; p < 0.01), further adjustment by smoking and NYHA functional class in Model II (HR, 12.76; 95% CI, 2.85–57.13; p < 0.01), and final adjustment by ECG findings and BNP/NT-proBNP concentrations in Model III (HR, 7.52; 95% CI, 1.47–38.52; p = 0.02), the association of the dilated subtype with increased HF outcomes was still significant, while none of the other variables included in the regression model could partially explain the distinction of HF occurrence between the two groups. The gene discussed is NPPB; the disease is hydrops fetalis.
