We assessed endothelial glycocalyx, aortic elastic properties, left atrial and ventricular function in patients with lacunar, atherosclerotic and stroke of undetermined source (ESUS). Patients and methods In 75 patients (age 55.2 ± 10.6) with acute cerebral stroke (25 lacunar, 20 atherosclerotic and 30 ESUS) and 20 controls with similar risk factors, we measured: (1) perfused boundary region (PBR) of the sublingual arterial microvessels (range 5–25 µm), a marker inversely related with glycocalyx thickness, (2) pulse wave velocity (PWV), central systolic blood pressure (cSBP), and augmentation index (AIx), (3) Left atrial (LA) strain using speckle-tracking imaging, and (4) left ventricular global longitudinal strain. Results Compared with controls, patients with stroke had higher PWV (11.38 ± 3.62 vs 9.51 ± 1.57 m/sec, p = 0.045), PBR (2.10 ± 0.27 vs 1.94 ± 0.20, p = 0.039) and central SBP (139.64 ± 26.31 vs 116.36 ± 37.23 mmHg, p = 0.039), while ventricular (-17.902 ± 3.77 vs - 19.87 ± 1.17%, p = 0.025) and atrial deformation (24.8 ± 9.99 vs 39.05 ± 2.08%, p LA reservoir strain was more reduced in ESUS patients compared to other 2 stroke types (ESUS 21.7 ± 6.6%, Lacunar 25.6 ± 13.2%, atherosclerotic 22.3 ± 7.8%, P Regarding endothelial glycocalyx, PBR5-9 (the smallest vessels with diameter 5-9 μm) was higher in patients with ESUS than in the other two types of stroke (ESUS 1.22 ± 0.12 μm, LACUNAR 1.19 ± 0.12 μm, ATHEROSCLEROTIC 1.15 ± 0.09 μm, p PWV was significantly higher in patients with atherosclerotic stroke (15.57 ± 5.50 m/sec, p = 0.007), while in patients with lacunar it was mildly elevated (10.53 ± 3.22 m/sec) and in ESUS patients it was moderately increased (11.7 ± 3 m/sec). Conclusions Patients with stroke have impaired atrial strain, endothelial glycocalyx and arterial elasticity, compared with controls. Arterial stiffness is more affected in atherosclerotic stroke, while LA deformation and glycocalyx of small size micro vessels are more affected in ESUS patients.
