RAISED MODIFIED SHOCK INDEX (MSI) AS A PREDICTOR OF INHOSPITAL MORTALITY IN PATIENTS WITH ST-SEGMENT ELEVATION MYOCARDIAL INFARCTION (STEMI)

Abstract

Objective: To determine association of a raised modified shock index (MSI) within-hospital mortality in patients with ST-segment elevation myocardial infarction(STEMI).

Methodology: It was a cross sectional study conducted at CardiologyDepartment, Jinnah Hospital Lahore. Duration of the study was 6 months periodfrom 1st November, 2016 to 30th April, 2017. The patients were divided into twogroups, normal MSI and raised MSI. The cohort was followed up for 7 days foradverse outcome i.e. in hospital mortality. All the collected data was entered andanalyzed on SPSS version 17.

Results: The mean age of the patients in normal MSI group was 57.42±11.32years and in raised MSI group was 56.03±12.48 years. Male to female ratio ofthe patients was 0.9:1. In hospital mortality occurred in 27(22.50%) patients.Statistically 5.75 times protective effect of in-hospital mortality was noted innormal MSI group compared to raise group patients i.e. RR=5.7500 [95% CI;2.1160 to 15.6252].

Conclusion: The study concluded that normal MSI index has protective effect onin-hospital mortality as compared to raised MSI patients.
