Abstract
OBJECTIVE Endothelium-dependent (ED) and endothelium-independent (EI) flow-mediated vasodilatation (FMD) have been used as measures of systemic arterial vasodilatory reserve. In this study, we aimed to assess both ED-FMD and EI-FMD in different groups with pulmonary hypertension (PH), and to investigate the relationship of these measures with clinical, echocardiographic, and invasive parameters of diseases severity and targeted treatment status. METHODS Our study population comprised 41 patients with PH [28 (68.2%) women, age 46.3±19.6 years] including idiopathic pulmonary arterial hypertension, Eisenmenger syndrome, and chronic thromboembolic PH in whom diagnosis were confirmed in accordance with current guidelines and 17 age and sex-matched healthy controls. The brachial artery (BA) was used for assessment of FMD with Duplex ultrasound, and serial changes in diameter were recorded at baseline, 1, and 3 minutes after termination of 2-minute external occlusive compression for ED-FMD, and after sublingual intake of glycerol trinitrate for EI-FMD, respectively. RESULTS Compared with controls, overall the PH group showed significantly lower ED-FMD (0.65±0.21 vs. 0.30±0.23 and 0.65±0.18 vs. 0.24±0.21) and EI-FMD (0.67±0.15 vs. 0.37±0.25 and 0.75±0.20 vs. 0.32±0.24) responses at 1st and 3rd min (p<0.001 for all). All these changes in the values of ED-FMD and EI-FMD were comparable among the PH subgroups. Neither ED-FMD nor EI-FMD were correlated with measures of PH severity and targeted therapy (TT) status (p>0.05). CONCLUSION Our results suggest an impaired BA vasodilatory reserve in patients with PH regardless of the clinical subgroup. Although these findings seem to be consistent with systemic dysfunction, acute FMD may not reflect the severity of PH and cannot be used as a potential surrogate for outcome in this setting.

Peripheral microangiopathy in Eisenmenger syndrome: A nailfold video capillaroscopy study. Int J Cardiol 2021; 336:54-59. [PMID: 33741426 DOI: 10.1016/j.ijcard.2021.03.033] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/12/2020] [Revised: 03/08/2021] [Accepted: 03/12/2021] [Indexed: 02/06/2023]
Abstract
BACKGROUND Eisenmenger syndrome (ES) comprises a severe phenotype of pulmonary arterial hypertension characterized by angiopathy of the lung circulation. The aim of the present study was to demonstrate the presence of systemic microvascular abnormalities in patients with ES using nailfold video-capillaroscopy (NVC) and to identify potential correlations of nailfold capillaroscopic characteristics with non-invasive markers of systemic organ function. METHODS Α cross-sectional NVC study was performed in 17 consecutive patients with ES and 17 healthy controls matched for age and sex. NVC quantitative (capillary density, capillary dimensions, haemorrhages, thrombi, shape abnormalities) and qualitative (normal, non-specific or scleroderma pattern) parameters were evaluated. RESULTS Patients with ES [median age 40 (18-65) years, 11 women] presented reduced capillary density [8.8 (7.2-10.2) loops/mm vs. 9.9 (8.3-10.9) loops/mm, p = .004] and increased loop width [15.9 (10.3-21.7) μm vs. 12.3 (7.6-15.2) μm, p < .001], while they had significantly more abnormal capillaries than healthy controls [2.5 (0.9-5.4) abnormal loops/mm vs. 1.0 (0.0-1.7) abnormal loops/mm, p < .001]. NVC shape abnormalities in ES were positively correlated with NT-proBNP (r = 0.52, p = .03) and were negatively associated with estimated glomerular filtration rate (r = -0.60, p = .02). Additionally, capillary loop diameter was positively correlated with increased haemoglobin levels (r = 0.55, p = .03) and negatively correlated with reduced peripheral oxygen saturation (r = - 0.56, p = .02). CONCLUSIONS This study supports the hypothesis of peripheral microvascular involvement in ES parallel to pulmonary microangiopathy detected by NVC. Further longitudinal studies are needed to confirm our preliminary results.
