COMPLICATIONS AND IN-HOSPITAL MORTALITY RATES AFTER PCI OF PERCUTANEOUS CORONARY INTERVENTION IN ST ELEVATION MYOCARDIAL INFRACTION

Abstract

Background: Percutaneous Coronary Intervention (PCI) is the preferred method of revascularization inAcute ST Elevation Myocardial Infarction (STEMI).Primary Percutaneous Coronary Intervention has emerged as the therapy of choice in STEMI and selected cases of Non-ST Elevation Myocardial Infarction (NSTEMI). As Percutaneous coronary intervention (PCI) enters its fourth decade of use, it is now the most commonly performed revascularization therapy worldwide. Objective: To find out the clinical profile and outcomes of Percutaneous Coronary Intervention in ST Elevation Myocardial Infraction. Methods: It is a retrospective, single centre study, performed atDepartment of Cardiac Surgery, Sheikh FazilatunnessaMujib Memorial KPJ Specialized Hospital, Gazipur, Bangladesh. All patients who underwent PCI for STEMI from November 2018 to July 2020 were enrolled in this study. All the data were collected from hospital registry and cath lab records.Results: The Study showed that out of 232 patients who presented with STEMI, 74.5% were male with average age of57.39 years. The mean time of presentation after onset of symptom/s was 17.5 hours. About 66% patients presented in less than 12 hours of symptoms onset, 21% presented at 12-24 hours of symptoms onset and 13% patients presented late. Primary PCI was done in 87% of patients. Almost all patients (98.2%) underwent coronary artery stenting with drug eluting stents. Multivessel PCI during index procedure was done in 7 patients. TIMI III flow following PCI was achieved in 97% cases. Average LVEF at discharge was 44.73%. There were 8 deaths, all after Primary PCI. In-hospital mortality rates for patients presenting with and without cardiogenic shock were 38.46% and 1.59% respectively. The overall mortality rate was 3.98%.Conclusion: This study has reemphasized that PCI is effective in the management of STEMI cases in Bangladesh with improving mortality rates and decreasing complications. Minimizing the delayed presentation after the onset of symptoms should be one of the prime focuses for effective management of STEMI.
