EAT was measured with transthoracic echocardiography. Vascular function was assessed with flicker-light-induced vasodilation of retinal arterioles (FIDart%) and flow-mediated dilatation (FMD%) in conduit arteries. Patients with HFrEF have less EAT compared with patients with HFpEF (4.2 \u00b1 2 vs. 5.3 \u00b1 2 mm, respectively, P &amp;lt; 0.001). Interestingly, EAT was significantly associated with impaired microvascular function (FIDart%; r = \u22120.213, P = 0.012) and FMD% (r = \u22120.186, P = 0.022), even after multivariate correction for confounding factors (age, body mass index, hypertension, and diabetes; standardized regression coefficient (SRC) = \u22120.184, P = 0.049 for FIDart% and SRC = \u22120.178, P = 0.043 for FMD%) in HFrEF but not in HFpEF.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Although less EAT is present in HFrEF than in HFpEF, only in HFrEF EAT is associated with vascular dysfunction.
