Incidence of major adverse cardiac and cerebrovascular events following primary percutaneous coronary intervention in central iran

Objectives: ST-segment elevation myocardial infarction (STEMI) is a critical form of acute coronary syndrome that requires immediate myocardial reperfusion to reduce infarct size and enhance patient outcomes. Despite improvements in the management of STEMI, it continues to be a global contributor to mortality. This study aimed to evaluate the long-term prognosis and outcomes of STEMI patients by investigating the incidence of major adverse cardiac and cerebrovascular events. (MACCE).Methods: This prospective cohort study enrolled ۳۰۵ patients diagnosed with STEMI between March ۲۰۱۶ and February ۲۰۱۷ in Afshar Hospital, a tertiary cardiac hospital in central Iran. The researchers performed Primary percutaneous coronary intervention (PCI) using drug-eluting stents (DES), and patients received standard medical therapy. Data on major adverse cardiac and cerebrovascular events (MACCE), demographic characteristics, clinical factors, and procedural details were collected through patient interviews, medical records, and the myocardial infarction registry database.Results: The overall success rate of primary PCI was ۹۲.۸%. Hypertension was the most prevalent risk factor for coronary artery disease (۴۱.۱%). During the one-year follow-up, the incidence of MACCE was ۱۵.۱% (۴۶ patients), with death being the most common occurring in ۳۳ patients (۱۰.۸%). Mortality rates were highest within the first six months. The multivariate logistic regression analysis revealed that age (P=۰.۰۰۱) and stent length exceeding ۳۰ mm (P=۰.۰۳۶) were significant predictors of mortality.Conclusions: This study provides important insights into primary PCI outcomes in STEMI patients in central Iran. The findings indicate a high success rate for PCI and emphasize the necessity for timely and appropriate management. MACCE incidence, especially mortality, highlights the importance of ongoing surveillance and comprehensive follow-up care.
