After adjustment for age, cardiovascular risk factors and presence of pre-infarctual angina, only NT-proBNP values at admission independently predicted rLS (β = −0.58, 95% CI −5.43 to −1.68, p = 0.001), whereas iLS was predicted by NT-proBNP (β = −0.52, 95% CI −5.91 to −1.57, p = 0.001) and creatinine values (β = −0.34, 95% CI −9.51 to −0.52, p = 0.03), and bLS by non-anterior location of STEMI (β = −0.45 for anterior STEMI, 95% CI −8.00 to −1.42, p = 0.007). This evidence concerns the gene NPPB and angina pectoris.
