Correlation analysis with cardiac risk and NT-pro-BNP. (A) moderate correlation between N-terminal prohormone of brain natriuretic peptide (NT-proBNP) at the ER with cardiac risk Score 2 (r = 0.54; CI 0.1302 to 0.7940). Moderate Correlation between 10-year cardiac risk score and the troponin T concentration on day 1 (r = 0.41; CI 0.04792 to 0.6855) (B) and day2 (r = 0.42; CI 0.004517 to 0.6890) (C). (D) The ejection fraction (EF) in % correlated moderately with the levels of NT-proBNP (r=-0.54; CI-0.9760 to -0.6189). A stronger correlation between NT-proBNP and the left ventricular end-diastolic diameter (LVEDD) (r=-0.79; CI -0.9498 to 0.1292) (E) and further with the sPAP was strongly positively correlated with levels of NT-proBNP (r = 0.89; CI-0.3093 to 0.9598) (F)
