Objective: Recently, dynamic retinal vessel analysis (DVA) has gained interest for investigation of microvascular function but comparative measurements with standard methods like the forearm blood flow technique (FBF) are uncommon till now.
Methods: We recruited 23 high-risk cardiovascular patients (Risk) and 17 healthy persons (Ctrl). During the FBF experiment, postocclusive reactive hyperaemia (RH) as well as endothelium-dependent and independent vasodilation was measured by infusion of acetylcholine (ACh) and sodium nitroprusside (SNP) into the brachial artery.
Objective: Hypotensive episodes are relatively frequent adverse effects during LDL apheresis. To evaluate the impact of LDL apheresis on autonomic cardiovascular control we investigated hypercholesterolemic patients before and after a single LDL apheresis in comparison to an age-matched control group.
Methods: We continuously recorded systemic arterial blood pressure, electrocardiogram and respiration in 21 hypercholesterolemic patients (57 ± 15 years) on regular LDL apheresis treatment and 22 healthy control subjects (56 ± 4 years) during cardiovascular autonomic testing (metronomic breathing, Valsalva manoeuvre, head-up tilt).
