Patients were divided into two groups according to left ventricular ejection fraction (LVEF): AIC group if LVEF\u2009&lt;\u200950% and preserved LVEF group if LVEF\u2009\u2265\u200950%. A third group of patients with a recent diagnosis of dilated cardiomyopathy (DCM) and without AF was analyzed as control group. CMD was defined as abnormal coronary flow reserve (CFR\u2009&lt;\u20092.5) and\/or abnormal index of microcirculatory resistance (IMR\u2009\u2265\u200925).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Among 84 analyzed patients, 33 were in the AIC group, 39 in the preserved LVEF group, and 12 in the DCM group.
