Anterior Tragal Crease Is Associated With SYNTAX Score in Non-ST-Segment Elevation Myocardial Infarction

Abstract

The main aim of this study was to investigate the relation between anterior tragal crease (ATC) and coronary artery lesion complexity and severity assessed using the SYNTAX score (SXscore) in patients with non-ST-segment elevation myocardial infarction (NSTEMI). A total of 121 patients with a first-time diagnosis of NSTEMI were consecutively enrolled. ATC was defined as ≥1 crease that was close to the tragus and descended anteriorly. SXscore was calculated using the SXscore algorithm. The SXscore was higher in the ATC-positive group than in the ATC-negative group (11.85 ± 8.20 vs 7.52 ± 6.38, P = .003). In the univariate analysis, hemoglobin (male: 11.7-17.4 g/dL, female: 11.7-16.1 g/dL; P = .006), diabetes mellitus ( P = .031), current smoking ( P = .022), and presence of ATC ( P = .022) were significantly associated with increased SXscore. Multivariate analysis revealed ATC (95% confidence interval [CI]: 1.313-7.800, P = .011), current smoking (95% CI: 2.034-13.893, P = .001), and hemoglobin (95% CI: 0.433-0.822, P = .002) as independent determinants of increased SXscore. Anterior tragal crease is easily detected by physical examination. Presence of ATC in patients with NSTEMI may be a warning signal of complexity and severity of coronary artery disease (CAD).
