Microvascular Endothelial Function

Introduction: Studies have shown that primary aldosteronism (PA) has a higher risk of cardiovascular events than essential hypertension (EH). Endothelial dysfunction is an independent predictor of cardiovascular events. Whether PA and EH differ in the endothelial dysfunction is uncertain. Our study was designed to investigate the levels of biomarkers of endothelial dysfunction (Asymmetric dimethylarginine, ADMA; E-selectin, and Plasminogen activator inhibitor-1, PAI-1) and assess the microvascular endothelial function in patients with PA and EH, respectively. Methods: The biomarkers of endothelial dysfunction were measured by enzyme-linked immunosorbent assay (ELISA). Microvascular endothelial function was evaluated by Pulse amplitude tonometry (PAT). Results: Thirty-one subjects with EH and 36 subjects with PA including 22 with aldosterone-producing adenoma (APA) and 14 with idiopathic hyperaldosteronism (IHA) were enrolled in our study. The ADMA levels among the three groups were different (APA 47.83 (27.50, 87.74) ng/ml vs EH 25.08 (22.44, 39.79) ng/ml vs IHA 26.00 (22.23, 33.75) ng/ml; p = 0.04), however, when the APA group was compared with EH and IHA group, there was no statistical significance (47.83 (27.50, 87.74) ng/ml vs 25.08 (22.44, 39.79) ng/ml for EH, p = 0.11; 47.83 (27.50, 87.74) ng/ml vs IHA 26.00 (33.75) ng/ml, p = 0.07). The results of ADMA levels are presented as Median (p25, p75). Whereas, levels of PAI-1 and E-selectin, microvascular endothelial function were not significantly different between PA and EH subjects. Conclusions: Our study shows no significant differences between PA and EH in terms of biomarkers of endothelial dysfunction and microvascular endothelial function. The microvascular endothelial function of PA and EH patients is comparable.

The polymorphism of the genes involved in the regulation of endothelial function - PLAT, PAI-1, ACE, eNOS and TNF- - was studied in 122 pregnant women with pure and concomitant preeclampsia of varying severity and in 73 healthy puerperas. It was revealed that mutant genotypes of the studied genes are associated with more pronounced clinical and laboratory indicators of the severity of preeclampsia and the greatest increase in the level of markers of endothelial dysfunction. It is noted that the frequency of mutant genes and alleles varies depending on the severity of preeclampsia and the presence of background diseases characterized by the presence of endothelial dysfunction. The data obtained confirm the opinion that gestosis is a multifactorial disease with several, possibly independent, developmental pathways. The study of the polymorphism of genes regulating endothelial function contributes to the early identification of a risk group for the development of preeclampsia.

Background: Hypertension is associated with endothelial dysfunction and activated Rho-associated kinases (ROCKs) activity. Primary aldosteronism (PA) is a most common cause of secondary hypertension. Recent studies have shown that risk of cardiovascular events is higher in patients with PA than in patients with essential hypertension (EH). However, there is little information on the relationship between subtype of PA and the grade of atherosclerosis. The purpose of this study was to evaluate the vascular function and ROCK activity in patients with PA. Methods: Vascular function, including flow-mediated vasodilation (FMD) and nitroglycerin-induced vasodilation, and ROCK activity in peripheral leukocytes were evaluated in 21 patients with aldosterone producing adenoma (APA) group (50.7±14.3 years, 9 males), 23 patients with idiopathic hyperaldosteronism (IHA) group (55.8±9.9 years, 12 males), and 33 age-, gender-, and blood pressure-matched EH group (54.9 ± 10.7 years, 18 males). Results: FMD was significantly lower in the APA group than in the IHA group and EH group (3.2±2.0% vs. 4.6±2.3% and 4.4±2.2%, P<0.05, respectively), whereas there was no significant difference in FMD between the IHA group and EH group. There was no significant difference in the response of nitroglycerine in three groups. ROCK activity was significantly higher in the APA group than in the IHA group and EH group (1.29±0.57 vs. 1.00±0.46 and 0.81±0.36, P<0.05 and P<0.001, respectively), whereas there was no significant difference in ROCK activity between the IHA group and EH group. FMD correlated with age (r=-0.31, P<0.01), brachial arterial diameter (r=-0.44, P<0.01), plasma aldosterone concentration (PAC) (r=-0.35, P<0.01) and plasma renin activity ratio (ARR) (r=-0.34, P<0.01). ROCK activity correlated with age (r=-0.24, P=0.04), PAC (r=0.33, P<0.01) and ARR (r=0.46, P<0.01). Conclusions: APA was associated with both endothelial dysfunction and increased ROCK activity compared with those in IHA and EH. These findings suggest that APA may have a higher risk of future cardiovascular events.
