Pre-PCI hsTnT – preprocedural serum high-sensitivity troponin T level, post-PCI hsTnT – postprocedural serum high-sensitivity troponin T level, DM – diabetes mellitus, MI – myocardial infarction, PCI – percutaneous coronary intervention, CABG – coronary artery bypass grafting, ACEI/ARB – angiotensin-converting enzyme inhibitors/angiotensin receptor blockers.
The unit for age is per 1 year increase.
The unit for stent length is per 1 mm increase. β – β coefficient, p – probability value. P < 0.05 indicates statistical significance. Data were derived from multivariate regression analysis.
