NPPB and pulmonary arterial hypertension: The established SAE riskcalculation formula was logit(p) = –6.134 + 0.992 × pulmonaryartery hypertension (yes) + 1.459 × disease severity (severe) + 2.324× procedure type (diagnostic and interventional) + 1.436 × cTnI(≥0.028 μg/L) + 1.537 × NT-proBNP (≥126.65 pg/mL).The total score of the final risk score model based on the effect size of eachpredictor was 0 to 7, involving pulmonary artery hypertension (1 point), diseaseseverity (1 point), procedure type (2 points), cTnI (1 point) and NT-proBNP (2points), and the score greater than 3 means high risk.
