title: The Relationship Between Resting Heart Rate and SYNTAX Score in Patients With Stable Coronary Artery Disease.
abstract: We investigated the relationship between resting heart rate (HR) and The Synergy between percutaneous coronary intervention with Taxus and cardiac surgery (SYNTAX) score in patients with stable coronary artery disease (SCAD). A total of 420 patients who were admitted to our outpatient clinic for stable angina pectoris with sinus rhythm and had at least 50% narrowing in at least 1 coronary artery after coronary angiography were included in the study. Patients were divided into 3 tertiles based on the resting HR: HR of tertile 1 was ≤65 (n = 138), tertile 2 was between 66 and 76 (n = 139), and tertile 3 was ≥77 beats/min (n = 143). The SYNTAX score (7.6 ± 4.6, 12.4 ± 5.6, 20.3 ± 8.1; P < .001) was significantly higher for those in tertile 3 than for those in tertiles 1 and 2. Leukocyte count (7.8 ± 2.2, 7.9 ± 2.2, 8.4 ± 2.3 × 109/L; P = .035) and C-reactive protein (CRP) levels (2.4 ± 0.5, 3.2 ± 0.7, 4.5 ± 1.2 mg/L, P < .001) were increasing from the lowest to the highest tertile. Using multiple logistic regression analysis, CRP (odds ratio [OR] 1.54 [1.17-2.11], P = .001) and resting HR (OR 1.67 [1.25-2.19], P < .001) emerged as independent predictors of SYNTAX score. Resting HR is related to SYNTAX score in patients with SCAD.
