VALIDATION OF CAMI-NSTEMI SCORE IN ASSESING IN-HOSPITAL MORTALITY RISK IN NON ST ELEVATION MYOCARD INFARCT (NSTEMI) IN HAJI ADAM MALIK GENERAL HOSPITAL MEDAN

Abstract

Background : Risk Stratification in patient with acute myocardial infarction, especially NSTEMI, is clinically important. GRACE score and TIMI score are used frequently, although the number of Asian population represented in this risk score model was small. CAMI-NSTEMI score is a nover risk score to predict inhospital mortality derived from CAMI registry with Chinese population. This study aims to validate this score in North Sumatera.

Method : Data were collected from 50 patients diagnosed with NSTEMI in Haji Adam Malik General Hospital Medan consecutively. Baseline data, clinical findings, ECG, and laboratory findings were recorded, whereas mortality and major cardiovascular events (MACEs) were observed during inhospital care. CAMI-NSTEMI and GRACE score were counted. The new CAMI-NSTEMI score cutoff in this study were measured and compared with the CAMI-NSTEMI score from the novel study (sensitivity, specificity, positive predictive value, negative predictive value).

Result : From 50 patients, mortality was recorded in 6 patients (12%) whereas MACEs were recorded in 25 patients (52%). The CAMI-NSTEMI score cutoff in this study was <83.5, 83.5-115, >115 (low, moderate, high risk respectively). From data analysis, this study found the sensitivity (100%, 77.8%, 92.3) , spesificity (90.0%, 97.6%, 100%), positive predictive value (93.3%, 87.5%, 100%), and negative predictive value (100%, 95.2%, 97.4%) compared with the novel study for low, moderate and high risk respectively.

Conclusions : CAMI-NSTEMI Score is for assesing inhospital mortality risk in NSTEMI patients at Haji Adam Malik General Hospital Medan (North Sumatera).
