Stepwise multivariable analysis revealed that factors independently associated with postprocedural cTnI levels were age, prior myocardial infarction, NT-proBNP, preprocedural cTnI, number of target vessels, number of postdilation and total stent length were positively associated with postprocedural cTnI levels, whereas HbA1c levels were inversely associated with postprocedural cTnI levels (Table 3). Here, NPPB is linked to myocardial infarction.
