Comparison of MACE between High and Low TIMI Risk
Introduction: Patients with ST-segment elevation myocardial infarction (STEMI) have increased risk for death and adverse cardiac events. Of great concern is the risk of cardiac arrest that accounts for the majority of early deaths and other major adverse cardiac events. Significant hospital resources are dedicated to these high risk patients.
Objective: To see the correlation of MACE between High and Low TIMI Risk.
Methodology: This cross-sectional prospective study was conducted in the Department of Cardiology, Sylhet MAG Osmani Medical College Hospital, Sylhet during the period from July 2017 to June 2018. Fifty patients with definite diagnosis of acute STEMI, received streptokinase, aged above 18 years and both sex were included. Prior myocardial infarction, coronary revascularization procedures either CABG or angioplasty or coronary stenting; co-morbidities such as renal failure, heart failure, cardiomyopathy, valvular heart disease and congenital heart disease were excluded. On admission TIMI was recorded. In hospital MACE were also recorded.
Results: The mean age of patients was 52.64 (SD 11.88) years and majority of the patients were male (84%) with male to female ratio was 5.25:1. The mean TIMI risk score for STEMI 4.50 (SD 2.38). In hospital major adverse cardiac events (MACE) occurred in 19 (38.0%) cases. TIMI risk score for STEMI was significantly higher in patients with MACE compared to without MACE (16.95, SD 1.78 versus 3.00, SD 1.10; p<0.001) respectively.
Conclusion: In hospital major adverse cardiac events (MACE) occurred in 19 (38.0%) cases. TIMI risk score for STEMI was significantly higher in patients with MACE compared to patients without MACE (16.95, SD 1.78 versus 3.00, SD 1.10; p<0.001) respectively. From the study we conclude that TIMI risk score (5 or above) is a reliable tool in predicting in- hospital major adverse cardiac events in ST-segment elevation myocardial infarction.
