Endothelial Function Is Preserved in Patients with Wild-Type Transthyretin Amyloid Cardiomyopathy. J Clin Med 2023; 12:jcm12072534.

Abstract
Heart failure (HF) is associated with endothelial dysfunction. Vascular function per se plays an important role in cardiac function, whether it is a cause or consequence. However, there is no information on vascular function in patients with wild-type transthyretin amyloid cardiomyopathy (ATTRwt-CM). The purpose of this study was to evaluate vascular function in patients with ATTRwt-CM. We measured flow-mediated vasodilation (FMD) as an index of endothelial function and nitroglycerine-induced vasodilation (NID) as an index of vascular smooth muscle function and brachial artery intima-media thickness (bIMT) and brachial-ankle pulse wave velocity (baPWV) as indices of arterial stiffness in 22 patients with ATTRwt-CM and in 22 one-by-one matched control patients using vascular function confounding factors. FMD was significantly greater in patients with ATTRwt-CM than in the controls (5.4 ± 3.4% versus 3.5 ± 2.4%, p = 0.038) and the N-terminal pro-brain natriuretic peptide (NT-proBNP) level was significantly greater in patients with ATTRwt-CM than in the controls (2202 ± 1478 versus 470 ± 677 pg/mL, p < 0.001). There were no significant differences in NID, bIMT or baPWV between the two groups. There was a significant relationship between NT-proBNP and FMD in patients with ATTRwt-CM (r = 0.485, p = 0.022). NT-proBNP showed no significant relationships with NID, bIMT or baPWV. Conclusions: Endothelial function was preserved in patients with ATTRwt-CM. Patients with ATTRwt-CM may have compensatory effects with respect to endothelial function through elevation of BNP.

Abstract
Objective: Resveratrol (RV) is a polyphenol with antioxidant, anti-inflammatory and cardio-protective properties. Our objective was to investigate whether acute supplementation with high doses of RV would improve flow-mediated dilation (FMD) and oxygen consumption (VO2) kinetics in older coronary artery disease (CAD) patients. Design: We employed a placebo-controlled, single-blind, crossover design in which ten participants (aged 66.6 ± 7.8 years) received either RV or placebo (330 mg, 3× day-1) during three consecutive days plus additional 330 mg in the morning of the fourth day with a seven-day wash-out period in-between. On the fourth day, FMD of the brachial artery and VO2 on-kinetics were determined. Results: RV improved FMD in patients who had undergone coronary artery bypass grafting (CABG; -1.4 vs. 5.0%; p = .004), but not in those who had undergone percutaneous coronary intervention (PCI; 4.2 vs. -0.2%; NS). Conclusion: Acute high dose supplementation with RV improved FMD in patients after CABG surgery but impaired FMD in patients who underwent PCI. The revascularization method-related differential effects of RV may be due to its direct effects on endothelial-dependent dilator responses. Our findings have important implications for personalized treatment and stratification of older CAD patients.

Abstract
PURPOSE Testicular torsion without timely intervention causes incurable damage to the testis. We examined the causative role of microcirculatory injury in torsion induced testicular damage with particular regard to endothelin-A receptor activation. MATERIALS AND METHODS The microcirculatory consequences of testicular torsion were assessed in the presence or absence of endothelin-A receptor antagonism in rats. Microcirculatory perfusion changes (red blood cell velocity and pulsatile flow pattern alterations) were examined by an orthogonal polarization spectral imaging technique. Microcirculatory inflammatory alterations were assessed by fluorescence intravital video microscopy after 60-minute torsion followed by 240-minute reperfusion. As a specific endothelin-A receptor inhibitor, the antisense homology box derived peptide ETR-p1/fl was applied 10 minutes before reperfusion. Tissue accumulation of leukocytes was estimated by myeloperoxidase activity in tissue biopsies taken at the end of the 4-hour reperfusion period. In further experiments testicular weight as a marker of permanent damage was evaluated 45 days after torsion. RESULTS The physiological pulsatile flow pattern ceased in the initial phase of reperfusion while leukocyte-endothelial interactions increased throughout the examined reperfusion period. Endothelin-A receptor antagonism caused earlier return of pulsatile flow and recovery of red blood cell velocity, and alleviated microcirculatory inflammatory reactions and atrophy. CONCLUSIONS Results suggest a pathophysiological role of endothelin-A receptor activation in the pathogenesis of testicular torsion. This effect is related to deterioration in testicular perfusion and activation of microcirculatory inflammatory reactions.

Short-term effects of extended-release niacin with and without the addition of laropiprant on endothelial function in individuals with low HDL-C: a randomized, controlled crossover trial. Clin Ther 2014; 36:961-6. [PMID: 24768191 DOI: 10.1016/j.clinthera.2014.03.012] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2013] [Revised: 01/07/2014] [Accepted: 03/20/2014] [Indexed: 10/25/2022]
Abstract
BACKGROUND Reduced plasma concentration of high-density lipoprotein cholesterol (HDL-C) is associated with vulnerability to oxidative stress and propensity to endothelial dysfunction. Niacin directly activates both GPR-109A in leukocytes and the heme oxygenase-1 pathway, promoting strong anti-inflammatory and antioxidative effects, as well as induces immediate production of prostaglandin D2, leading to endothelial vasodilation. OBJECTIVE This study investigated the short-term effects of extended-release niacin (ERN) administered with or without the prostaglandin D2 receptor antagonist laropiprant on endothelial function in patients with low HDL-C. METHODS Asymptomatic men and women aged between 20 and 60 years who had plasma HDL-C levels <40 mg/dL were treated with ERN monotherapy 1 g/d or ERN/laropiprant 1 g/20 mg (ERN/LRP) in a crossover study design. The sequence of treatments was decided by simple randomization. Plasma samples and flow-mediated dilation (FMD) of the brachial artery were obtained at baseline, day 7 of treatment period 1, day 7 of washout, and day 7 of treatment period 2. RESULTS Eighteen patients were enrolled (mean [SD] age, 42 [17] years; 11 men). Triglyceride levels decreased by 4% and 3%, and HDL size decreased by 5.8% and 6.2%, with ERN and ERN/LRP, respectively (both, P < 0.05). There were no changes in HDL-C levels or in cholesteryl esterase transfer protein activity with either treatment. The median increases in FMD were 4.5% and 4.1% with ERN and ERN/LRP, which receded after washout. On intergroup analysis, there were no differences with respect to variation in plasma HDL-C, triglycerides, C-reactive protein, direct bilirubin, or FMD. CONCLUSIONS In these patients, the addition of laropiprant did not influence the effects of niacin on endothelial function. Based on these findings, short-term niacin treatment might improve endothelial function in patients with low HDL-C levels. ClinicalTrials.gov identifier: NCT01942291.

Abstract
Re-stenosis or remodeling of coronary and peripheral arteries remains a major complication following balloon-angioplasty or stenting. This study was designed to investigate the effect of nesiritide, a recombinant B-type natriuretic peptide (BNP), on vascular remodeling following balloon-induced endothelial injuries. Twenty-eight male New Zealand rabbits were divided into nesiritide-treated (0.1 mg/kg/day, sc, for 4 weeks, n = 10), saline-treated control (n = 10) and sham-operated groups (n = 8). In the nesiritide and control groups, a balloon catheter was inserted to the right iliac artery to induce injuries. Vascular endothelial growth factor (VEGF) was measured by immunohistochemistry. The area under internal elastic membrane of the arterial wall (643.2 ± 134.1 vs 493.7 ± 139.3 µm(2), p < 0.05) and the area under external elastic membrane (1495.1 ± 204.9 vs 1265.9 ± 232.6 µm(2), p < 0.05) in the nesiritide group were greater than those in the control group, but were smaller than those in the sham-operated group (p < 0.05). The stenosis ratio was lower in the nesiritide group than in the control group (18.7 ± 7.7% vs 38.0 ± 8.3%, p < 0.01). Importantly, the VEGF expression rate was significantly lower in the nesiritide group than in the control group (42.2 ± 8.8% vs 56.1 ± 13.1%, p < 0.05), while there were no signs of VEGF expression in the non-injured arteries of the three groups. In conclusion, nesiritide treatment reduces the stenosis of the rabbit iliac artery following balloon-induced endothelial injuries probably by decreasing VEGF expression.
