Periprocedural myocardial infarction patients had significantly lower scores of BI (96.1 ± 10.1 vs. 97.1 ± 8.4, P < 0.001) and higher proportions of impaired ADL (22.2% vs. 17.1%, P < 0.001); higher cTnI fold-elevation, higher levels of baseline white blood cell (WBC), C-reactive protein (CRP), N-terminal pro-brain natriuretic peptide (NT-proBNP), and lower levels of estimated glomerular filtration rate (eGFR) and platelet counts (all P values < 0.05) also were noted among this group of patients in comparison with patients without occurring periprocedural myocardial infarction. The gene discussed is TNNI3; the disease is myocardial infarction.
