Prediction of clinical outcomes of patients treated with percutaneous coronary intervention for ST-Elevation myocardial infarction using familial history of premature coronary artery disease

Abstract

Introduction: ST-elevation myocardial infarction (STEMI) is a relatively common cause of mortality among patients. The effects of risk factors as predictors of mortality in patients has been shown in different studies. The present study was performed aiming to evaluate the association between a family history of premature coronary artery diseases (CADs) with clinical outcomes among patients treated with percutaneous coronary intervention (PCI) for STEMI. Methods: This descriptive-analytical study was conducted in Shahid Madani Hospital of Tabriz University of Medical Sciences, Tabriz, Iran, on 200 patients with STEMI with a PCI. 100 out of these 200 patients had a family history of premature CAD. Patients were followed up within 48 hours after PCI, as well as one year after admission, and the secondary outcomes including myocardial infarction (MI), heart failure, ventricular arrhythmias (VAs), pulmonary edema, and death were evaluated. Results: The mean age of the patients with positive and negative family history of premature CAD was 56.37 ± 8.20 and 61.72 ± 7.42 years, respectively. The mean age of the patients with a family history of a premature CAD was significantly lower than that of patients without a family history of a premature CAD (P = 0.001). There was no significant difference in the frequency of CAD risk factors, angiographic findings, and its complications, ST-segment resolution and frequency of secondary outcomes during 48 hours and one year after admission between the study groups (P > 0.050). Conclusion: The present study showed that a family history of premature CAD does not predict the clinical outcomes in patients treated with PCI for STEMI which should be validated across future studies.
