Abstract Background The assessment of coronary flow velocity reserve (CFVR) on left anterior descending coronary artery (LAD) expands the risk stratification potential of stress echocardiography (SE) based on regional wall motion abnormalities (RWMA). Aim To assess the feasibility and functional cor...

description Abstract Background The assessment of coronary flow velocity reserve (CFVR) on left anterior descending coronary artery (LAD) expands the risk stratification potential of stress echocardiography (SE) based on regional wall motion abnormalities (RWMA). Aim To assess the feasibility and functional correlates of CFVR. Methods In a prospective, observational, multicenter study, we initially screened 3,410 patients (2061, 60%, male; age 63±11 years; ejection fraction, EF=61±9%) with known or suspected coronary artery disease (CAD) and/or heart failure (HF). All patients underwent SE (exercise, n=1288; vasodilator, n=1860; dobutamine, n=262) based on RWMA in 20 accredited laboratories of 8 countries. CFVR was calculated as the stress/rest ratio of diastolic peak flow velocity pulsed-Doppler assessment of LAD flow. We also assessed B-lines (a sign of pulmonary congestion) with lung ultrasound and left ventricular contractile reserve (LVCR) based on Force (systolic blood pressure/end-systolic volume). Results The success rate for CFVR on LAD was 3,002/3,410 (feasibility=88%): 1,025/1,288 for exercise (80%), 1,766/1,860 (95%) for vasodilator (dipyridamole, n=1,841 and adenosine= 18) and 211/262 (81%) for dobutamine (p
