Abstract
OBJECTIVE
Major adverse cardiovascular events occurrences of patients with different cardiac troponin-I (cTnI) levels following percutaneous coronary intervention (PCI) remained controversial. The prognostic relevance and risk factors of PCI-related myocardial infarction (MI) were not very clear as well.
PATIENTS AND METHODS
Our study included 249 coronary artery disease patients without preoperative cTnI elevation who successfully accepted PCI from 2013 to 2014. A three-year follow-up was conducted for each patient. The patients were divided into PCI-related MI group and non-PCI-related MI group. Risk factors of PCI-related MI were first explored. The occurrence of MACE was recorded. The prognostic relevance between PCI-related MI (PMI) group and non-PCI-related MI group, as well as different postoperative cTnI levels, were compared.
RESULTS
Low-density lipoprotein cholesterol (LDL-C), age, Gensini Score, total stent length, and intra-operative complication were found positively correlated with PCI-related MI occurrence, while hemoglobin and prior PCI history were negatively correlated. After 3-year follow-up, the Kaplan-Meier survival curve showed MACE occurrence was significantly increased in PCI-related MI group. Comparing to patients with normal postoperative cTnI, MACE occurrence was increased in patients with a 10×upper limit of normal (ULN)≤cTnI<70×ULN and cTnI≥70×ULN, while there was no difference in patients with 1×ULN≤cTnI<5×ULN and 5×ULN≤cTnI<10×ULN. Cox proportional hazard regression analysis revealed PMI, NT-proBNP, and left ventricular ejection function (LVEF)<50% were positively correlated with MACE occurrence, while maximum inflation pressure and apoA-I were negatively correlated.
CONCLUSIONS
Prognosis of PCI-related MI was poor, as well as in patients with postoperative cTnI≥10×ULN. Among the risk factors of PMI, LDL-C, age, Gensini Score, total stent length, and intra-operative complication were positively correlated with PCI-related MI occurrence, while hemoglobin and prior PCI history were negatively correlated.
