BackgroundIschemic heart disease is the leading cause of mortality worldwide, and its prevalence is rising.ObjectiveThe goal of this study was to evaluate the HEART and T-MACS scores for predicting major cardiac events (MACE) in patients presenting to the emergency department with chest pain.MethodThis study was single center and prospectively conducted. The demographic information, T-MACS and HEART scores of the participants were recorded and calculated. Acute myocardial infarction (AMI), mortality, and the need for coronary revascularization were considered as major adverse cardiac events (MACEs). The statistical analysis was carried out using SPSS (IBM Statistics, New York) version 24, and significance was determined at the p < 0.05 level.ResultsThe 514 patients included in our study had a mean age of 52.01 ± 19.10 years, with 55.3% were female and 44.7% was male. A total of 78(%15.1) cases were diagnosed with AMI. Fifty patients (%9.7) underwent percutaneous coronary intervention, 12 (%2.3) patients underwent coronary artery by-pass graft, and 8 (%1.5) patients died within a one-month period. The sensitivity and negative predictive values of the T-MACS score for the very low risk classification were 93.90% (86.3%-98.0%) and 97.7% (94.7%-99.0%), respectively, and the sensitivity and negative predictive values of the HEART score for the low risk classification were 89.59% (77.3%-93.1%) and 96.6% (94.2%-98.0%), respectively. The specificity and positive predictive values for the high risk classification were 99.77% (98.7%-100%) and 97.2% (82.9%-99.6%), respectively for the T-MACS score and 95.14% (92.7%-97%) and 63.2% (51.4%-73.5%), respectively for the HEART score.ConclusionThe T-MACS score was shown to be more accurate than the HEART score in predicting low risk (very low risk for the T-MACS score), high risk, and anticipated one-month risk for MACE in patients coming to the emergency department with chest pain.Copyright © 2022 Elsevier Inc.
