Regarding the risk factors for cardiovascular diseases, multivariate logistic regression showed that hypertension, diabetes, stroke, LDH level, BMI, and tidal volume were positively correlated with CHD prevalence; diabetes, PTE, PCO2, PO2, MVV, and neutrophil granulocyte percentage were correlated with heart failure prevalence; and PTE, PCO2, BNP and LDH levels, and mean SpO2 were correlated with PAH prevalence (Table 5). Here, NPPB is linked to cardiovascular disorder.
