In Hospital Outcomes of Patients with ST Segment Elevation Myocardial Infarction, Late for Thrombolysis

Abstract

Background: Myocardial infarction (MI) especially with ST segment elevation MI (STEMI) is a highly morbid and fatal entity and can result in various electrophysiological and mechanical complications during in hospital stay. Objective: To determine the in hospital outcomes of patients with ST segment elevation myocardial infarction, late for thrombolysis. Material and methods: This descriptive cases series was conducted at Rehmatul Lil Alameen Institute of Cardiology, PESSI, Lahore during 01-06-2018 to 31-12-2018. The cases of both genders with age 30 years or more, having ST elevation MI who were late for thrombolysis were included. The patients were looked for various outcomes like cardiogenic shock, left ventricular thrombus, heart block, death or discharge from the hospital. Results: In this study out of 105 cases, 74 (70.5%) males and 31 (29.5%) females. The mean age was 58.40 ± 11.19 years and mean duration of hospital stay was 6.77 ± 3.34 days. LV clot was seen in 7 (6.67%) of the cases, cardiogenic shock in 23 (21.9%) and complete heart block in 4 (3.81%) of the cases. Out of 105 cases, 9 (8.57%) died while rest were discharged. Regarding different types of MI, death was seen in 5 (8.1%) cases in AWMI, 4 (10%) in IWMI and none in LWMI out of their respective groups with p= 0.81. Conclusion: STEMI is a highly morbid entity in cases those are late from thrombolytic and cardiogenic shock is the most common complication observed.
