P328 Relation between CHA2DS2-VASc and impaired heart rate recovery in patients without inducible myocardial ischemia

Abstract Background Heart rate recovery (HRR) has been shown to predict cardiovascular and all-cause morbidity and mortality in different populations. Recent studies have indicated the CHA2DS2-VASc score can be used as predictor of mortality in patients with coronary artery disease, without atrial fibrillation. However, the relation between these two parameters has not yet been documented. The Aim: The aim of this study was to determine the relation between CHA2DS2-VASc score and impaired heart rate recovery in patients without inducible myocardial ischemia. Methods Our study comprised of 2699 consecutive patients (1319 male, 42.8%, average age 60 ± 11 years) who underwent treadmill exercise testing (stress echocardiography or stress echocardiography) according to Bruce protocol for the assessment of myocardial ischemia. We excluded patients with the systolic heart failure (left ventricle ejection fraction
