NPPB and Abnormal renal physiology: After adjusting for age, renal dysfunction, NT-proBNP, CTO, calcification, rotational atherectomy, LM PCI, multivessel PCI and total stent length, multivariable logistic regression analysis demonstrated that impaired ADL was also an independent risk factor for the incidence of periprocedural myocardial injury (Model 3 in Table 3: OR = 1.131, 95% CI [1.017, 1.257], P = 0.023).
