Comparison of six decision aid rules for diagnosis of acute myocardial infarction in elderly patients presenting to the emergency department with acute chest pain
Abstrakt
OBJECTIVE: This study aimed to evaluate the accuracy and effectiveness of different strategies for the diagnosis of acute myocardial infarction (AMI) in the elderly in real-life clinical practice. METHODS: Patients older than 70 years presenting to the emergency department with chest pain were included.
The performance of six decision aid rules (T-MACS, HEART, EDACS, TIMI, GRACE, and ADAPT) and solo troponin T strategy for diagnosing AMI was evaluated by calculating sensitivity, specifi city, odds ratios, negative and positive predictive values. RESULTS: A total of 250 patients, with a mean age of 78.5 years, were enrolled.
Forty-eight patients (19.2 %) had an acute myocardial infarction in a 30 day follow-up period. The sensitivity for ruling-out AMI was 100 % for T-MACS, HEART, and ADAPT; 97.9 % for EDACS, 93.8 % for TIMI, and 81.3 % for GRACE and solo TnT strategy.
For ruling-in AMI, the specifi city was 97.5 % for T-MACS, 95 % for TIMI, 83.2 % for HEART, 81.7 % for GRACE, and 46 % for ADAPT. CONCLUSION: T-MACS decision aid had the best performance for rule-out and rule-in diagnostics of AMI.
Risk stratifi cation of patients with suspected acute coronary syndrome based on decision aid rules can be used in real-life practice, even in the population of the elderly (Tab. 6, Fig. 1, Ref. 17). Text in PDF www.elis.sk
