Frequency of COVID-19 in patients with myocardial infarction treated with primary percutaneous coronary intervention

Introduction: COVID-19 is a disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) There are some evidences that myocardial injury may play a role in increasing mortality in patients with COVID-19. In this study, we investigated the prevalence of COVID-19 in patients with myocardial infarction treated with primary percutaneous coronary intervention (PCI) and demographic and clinical indicators of patients with this complication for a six months period. Methods: : This cross-sectional study was retrospective and descriptive and all patients with acute myocardial infarction under primary PCI including 85 patients were included in the study. Measured parameters included COVID-19, age, sex, ethnicity, diabetes, and hypertension. Data were analyzed by SPSS.v25 software . Results: : 14 patients with MI under primary PCI (16.5%) had COVID-19. COVID-19 was diagnosed by RT-PCR for 2 patients and by lung CT scan of the remaining 12. Background Diabetes and Hypertension were present in 21.4% (n = 3) and 7.1% (n = 1) of COVID-19 patients, respectively. Recurrence of MI occurred in 14.3% (2 cases) of patients with COVID-19. The death occurred in only one case of COVID-19 patients, a 70-year-old Persian woman with diabetes and hypertension. There was no significant difference between age and sex, ethnicity, underlying diabetes, and underlying hypertension between COVID-19 and non-COVID-19 groups. Conclusion: The prevalence of COVID-19 is significant in MI patients undergoing primary PCI. Further studies are recommended to investigate the role and mechanism of demographic and contextual variables on the severity and consequences of primary PCI in MI patients with COVID-19.
