CMD was assessed by Doppler echocardiography in the left anterior descending artery as coronary flow velocity reserve (CFVR). Patients were followed for a composite outcome of cardiovascular death, myocardial infarction (MI), heart failure, stroke, and coronary revascularization. CFVR was obtained in 1681 patients (91%) and the median CFVR was 2.33 (quartiles 1\u20133: 2.00\u20132.74). During a median follow-up of 4.5\u2009years, 96 events occurred. In univariate Cox regression, CFVR was associated with the composite outcome {hazard ratio (HR) 1.07 [95% confidence interval (CI) 1.03\u20131.11] per 0.1 unit decrease in CFVR; P\u2009&amp;lt;\u20090.001}, primarily driven by an increased risk of MI and heart failure. Results remained significant in multivariate analysis [HR 1.05 (95% CI 1.01\u20131.09) per 0.1 unit decrease in CFVR; P\u2009=\u20090.01]. In exploratory analyses, CFVR was also associated with the risk of repeated hospital admission for angina and all-cause mortality.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion\u2003<\/jats:title>\n                  <jats:p>Assessment of CFVR by echocardiography is feasible and predictive of adverse outcome in women with angina and no obstructive CAD.
