A PROSPECTIVE STUDY TO IDENTIFY THE BEST PREDICTOR OF IN-HOSPITAL MORTALITY IN PATIENTS UNDERGOING EMERGENT PERCUTANEOUS CORONARY REVASCULRIZATION; COMPARATIVE ANALYSIS OF FOUR WELL ESTABLISHED RISK SCORES

Objectives: This study was conducted to compare the predictive power of Shock Index (SI), TIMI Risk (TRI), LASH Score, and ACEF Score for prediction in-hospital mortality in a contemporary cohort ST-segment elevation myocardial infarction (STEMI) patients undergoing primary percutaneous coronary intervention (PCI) at tertiary care cardiac center developing country.
 Methodology: Consecutive diagnosed with STEMI PCI were included this study. SI, TRI, LASH, computed their assessed as area under curve (AUC) on receiver operating characteristics (ROC) analysis mortality.
 Results: A total 977 study, 780 (79.8%) which male, mean age 55.6 ± 11.5 years 149 (15.3%) 45 age. At presentation, 101 (11.4%) Killip class III/IV, 121 (12.4%) had arrhythmias, 59 (6%) arrest, 130 (13.3%) intubated. The rate 4.3% (42). AUC TRI 0.669 (cut-off: ≥17.5, sensitivity: 76.2%, specificity: 45.6%). SI 0.595 ≥0.9, 21.4%, 89.8%). score 0.745 ≥0, 66.9%). 0.786 ≥1.66, 71.4%, 73.5%).
 Conclusion: In conclusion, showed sufficiently high good sensitivity specificity compared other three scores. These simplified indices based readily available hemodynamic parameters can be reliable alternatives computational complex scoring systems risk stratification patients.
