Utilizing the hazard ratio of each parameter, a risk score was formulated to predict 1-year cardiac mortality, calculated as follows: 1.28 × (number of heart failure admissions) + 1.95 × (utilization of intravenous inotropes) + 2.40 × (common logarithm of plasma BNP [pg/mL]). This evidence concerns the gene NPPB and heart failure.
