Objective: To study the correlation of QRS complex after percutaneous coronary intervention (PCI) with myocardial ischemia reperfusion injury and apoptosis molecule contents. Methods: Patients with non-ST-segment elevation myocardial infarction who were treated in Nanchong Central Hospital between June 2014 and August 2016 were selected and divided into the PCI group who received emergency PCI surgery and the control group who accepted selective PCI or refused emergency PCI after the medical data were retrospectively analyzed. The fQRS as well as the contents of ischemia reperfusion injury indexes and apoptosis molecules was determined after 1 week of treatment. Results: The incidence of fQRS in PCI group was significantly lower than that in control group; serum MDA, cTnI, H-FABP, sTWEAK, sFas, sTRAIL and Caspase-3 contents as well as peripheral blood Nrf-2 and HO-1 expression of PCI group were greatly lower than those of control group; serum MDA, cTnI, H-FABP, sTWEAK, sFas, sTRAIL and Caspase-3 contents as well as peripheral blood Nrf-2 and HO-1 expression of PCI group of patients with fQRS complex (+) were greatly higher than those of patients with fQRS complex (-). Conclusion: The occurrence of fQRS after PCI is closely related to myocardial ischemia reperfusion injury and apoptosis.
