After excluding 615 patients (11.4%) with elevated cTnI at baseline, 551 (10.2%) with myocardial infarction within 30 days of PCI, and 158 (2.9%) in whom PCI was unsuccessful, 4059 patients met the inclusion criteria and constituted the study population (Fig. 1). Here, TNNI3 is linked to myocardial infarction.
