This study aim to analyze the AAC predicts TIMI and Killip scores based on chest X-ray examinations in patients with STEMI. This study is an observational analytical research with a diagnostic test design on 100 STEMI patients who had chest X-rays at Adam Malik Hospital and were evaluated for aortic arch calcification (AAC) scores semi-quantitatively. Analyzing the prediction of TIMI and Killip scores based on aortic arch calcification. Based on the analysis results, AAC in predicting TIMI score has a sensitivity of 48.6% and a specificity of 72.3% (AUC: 0.644). The Killip score has a sensitivity of 37.1% and a specificity of 78.5% (AUC: 0.562). The Positive Predictive Values of TIMI and Killip, respectively, are 64.6% and 64.2% and Negative Predictive Values are 57.5% and 54.5%. AAC is inadequate in predicting TIMI and Killip scores for patients with STEMI.
