It is unclear if CTEPD is associated with exercise pulmonary hypertension (ePH). This cross-sectional study aimed to determine the occurrence of ePH in patients with CTEPD and to identify the haemodynamic changes during exercise. We recruited 36 patients with persistent dyspnoea and residual perfusion defects by ventilation/perfusion scintigraphy from a large cohort of patients with previous pulmonary embolism. All patients underwent exercise right heart catheterization before being classified into the following groups: (1) CTEPD without ePH; comprising patients with normal mean pulmonary artery pressure (mPAP) of ≤20 mmHg, but with mPAP/cardiac output (CO) slope of ≤3 mmHg/L/min, (2) CTEPD with ePH (CTEPD-ePH); those with CTEPD with an mPAP/CO slope of >3 mmHg/L/min, (3) chronic thromboembolic pulmonary hypertension (CTEPH); those with mPAP >20 mmHg, pulmonary arterial wedge pressure (PAWP) ≤ 15 mmHg and pulmonary vascular resistance >2 WU. The postcapillary contribution during exercise was considered present if the PAWP/CO slope of >2 mmHg/L/min. CTEPD without resting pulmonary hypertension (PH) was present in 29 (81%) of the 36 patients, of whom six (21%) had ePH, while five (14%) had CTEPH. Two patients had unclassified PH. Two (33%) of the six patients with CTEPD-ePH had a PAWP/CO slope of >2 mmHg/L/min, compared with two (40%) of the five of those with CTEPH.

Patients with an LVAD implanted within the prior 90 days who had persistent PH (i.e., mean pulmonary arterial pressure ≥25 mmHg, pulmonary artery wedge pressure [PAWP] ≤18 mmHg, and pulmonary vascular resistance [PVR] >3 Wood units [WU]) were randomized (1:1) to macitentan 10 mg or placebo once daily for 12 weeks. The primary endpoint was change in PVR. Secondary endpoints included change in right-heart catheterization hemodynamic variables, N-terminal prohormone of brain natriuretic peptide levels, World Health Organization functional class, and safety/tolerability. Fifty-seven patients were randomized to macitentan (<i>n</i> = 28) or placebo (<i>n</i> = 29).

HHT is characterised by aberrant signalling via the transforming growth factor β (TGFβ) pathway, with loss of vascular integrity, angiogenesis and vascular dysplasia. The disease has an estimated prevalence of 1 in 5000 persons and the penetrance increases with increasing age. HHT commonly presents with epistaxis and telangiectasia, while visceral arteriovenous malformations are not uncommon. Mutations in the ENG, ACVRL1 and MADH4 genes account for 97% of all HHT cases, and it is recommended that genetic tests are used in combination with the clinical Curaçao criteria to confirm the diagnosis. HHT can be complicated by significant pulmonary vascular disease including pulmonary arteriovenous malformations, pulmonary arterial hypertension and high output cardiac failure. These are associated with substantial morbidity and mortality and therefore timely diagnosis is important to mitigate complications and optimise preventative strategies. This article outlines important advances in our understanding of the pathobiology of HHT and current recommendations regarding the diagnosis and screening of HHT with a specific focus on adult patients with pulmonary vascular disease.

Branched-chain amino acids (BCAAs), particularly leucine, are essential for various metabolic and physiological processes involved in heart development. In this study, we examined the molecular mechanisms through which elevated levels of leucine induce defects in cardiac microvascular endothelial cells. We collected plasma samples from healthy controls and neonatal patients with CHDs, employed a high-leucine diet for pregnant female mice, and applied high-leucine treatment in human cardiac microvascular endothelial cells (HCMECs). The impacts of high-leucine levels on WD Repeat Containing Planar Cell Polarity Effector (WDPCP)/MAPK signaling axis were investigated in the cell and animal models. We reported heightened plasma leucine levels in neonatal patients with CHDs and observed that a high-leucine diet in pregnant mice was associated with reduced expression of WDPCP and attenuated MAPK/ERK signaling. High-leucine treatment in HCMECs impaired epithelial-mesenchymal transition (EMT) and cell migration; however, overexpression of WDPCP or activation of MAPK exhibited a rescue effect. The upregulation of endomucin (EMCN) under high-leucine conditions contributed to the impaired EMT and migratory capacity of HCMECs, and the WDPCP/MAPK signaling axis regulated EMCN overexpression in response to high-leucine treatment. High levels of leucine in neonatal patients with CHDs may inhibit the WDPCP/MAPK axis, leading to an increase in EMCN expression that undermines the function of cardiac microvascular endothelial cells. These findings suggest the potential of targeting the WDPCP/MAPK axis as an intervention strategy for neonatal CHDs.</p>","PeriodicalId":20927,"journal":{"name":"Pulmonary Circulation","volume":"14 4","pages":"e70013"},"PeriodicalIF":2.2,"publicationDate":"2024-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11582015/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142710789","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

RV MW was calculated by longitudinal strain and simultaneous catheter pressure measurements in 14 patients with PH. Wasted MW was defined as the ratio of inappropriate myocardial lengthening to favorable shortening work. Segment-wise and averaged MW and wasted MW were evaluated at baseline and during pulmonary vasodilation therapy with oxygen and nitric oxide, and their relationship to hemodynamic measurements was analyzed. We found that MW was higher for the lateral wall than the septum: 1013 ± 374 mmHg · % versus 532 ± 190 mmHg · % at baseline. Wasted MW ratio did not differ significantly between wall regions.
