COMPARING UTILIZATION OF TIMI RISK INDEX VERSUS KILLIP CLASS AT PRESENTATION IN DETERMINING THE NEED OF ADMISSION TO CORONARY CARE UNIT FOR ACUTE ST ELEVATION MYOCARDIAL INFARCTION PATIENT AFTER SUCCESSFUL PRIMARY PERCUTANEOUS CORONARY INTERVENTION: SINGLE CENTRE STUDY

Background: With the ever-increasing number of acutely ill patients with cardiac disease that need intensive monitoring and limited resources in coronary care unit (CCU), there is a need to ensure appropriate admission to CCU. Studies have shown that Killip 1 patients who had successful primary percutaneous coronary intervention (PPCI) for ST Elevation Myocardial Infarction (STEMI) can be admitted safely to a step-down unit. However, Killip class was a subjective assessment. We attempt to compare TIMI risk index {TRI = [heart rate X (age/10)2]/systolic blood pressure} versus Killip Class at presentation in determining the need of admission to CCU for STEMI patient after successful PPCI. TRI was a robust predictor (for STEMI patients on irst arrival in hospital) and high discriminatory capacity of in-hospital events in each of the ive risk subgroups.
