Simple regression analyses revealed that age, prior MI, NT-proBNP, creatinine, preprocedural cTnI, number of target vessels, number of B2/C type lesions, number of bifurcation lesions, number of predilation, number of postdilation, use of kissing balloon, maximum inflation pressure, number of stents and total stent length were positively associated with postprocedural cTnI levels, whereas high hemoglobin levels were associated with low postprocedural cTnI levels. This evidence concerns the gene NPPB and myocardial infarction.
