Cardiopulmonary exercise testing (CPET) has shown promise in better characterizing these patients. In this systematic review and pooled analysis, we aim to use CPET data from PE survivors to understand PPES better. A literature search was conducted in PubMed, EMBASE, and Cochrane for studies reporting CPET results in post-PE patients without known pulmonary hypertension published before August 1, 2023. Studies were independently reviewed by two authors. CPET findings were subcategorized into (1) exercise capacity (percent predicted pVO₂ and pVO₂) and (2) ventilatory efficiency (VE/VCO₂ slope and V_D/V_T). We identified 14 studies (<i>n</i> = 804), 9 prospective observational studies, 4 prospective case-control studies, and 1 randomized trial. Pooled analysis demonstrated a weighted mean percent predicted pVO₂ of 76.09 ± 20.21% (<i>n</i> = 184), with no difference between patients tested <6 months (<i>n</i> = 76, 81.69±26.06%) compared to ≥6 months post-acute PE (<i>n</i> = 88, 82.55 ± 21.47%; <i>p</i> = 0.817). No difference was seen in pVO₂ in those tested <6 months (<i>n</i> = 76, 1.67 ± 0.51 L/min) compared to ≥6 months post-acute PE occurrence (<i>n</i> = 144, 1.75 ± 0.57 L/min; <i>p</i> = 0.306). The weighted mean VE/VCO₂ slope was 32.72 ± 6.02 (<i>n</i> = 244), with a significant difference noted between those tested <6 months (<i>n</i> = 91, 36.52 ± 6.64) compared to ≥6 months post-acute PE (<i>n</i> = 191, 31.99 ± 5.7; <i>p</i> < 0.001). In conclusion, this study, which was limited by small sample sizes and few multicenter studies, found no significant difference in exercise capacity between individuals tested <6 months versus ≥6 months after acute PE. However, ventilatory efficiency was significantly improved in patients undergoing CPET ≥ 6 months compared to those <6 months from the index PE.</p>","PeriodicalId":20927,"journal":{"name":"Pulmonary Circulation","volume":"14 4","pages":"e12451"},"PeriodicalIF":2.2,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11465457/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142401115","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}

Decreased levels of the expression of PPARγ and ETV2 along with reduced endothelial and increased EndoMT markers are consistently observed in lungs and pulmonary artery endothelial cells (PAECs) of idiopathic pulmonary arterial hypertension patients, in hypoxia-exposed mouse lungs, human PAECs, and in induced-EndoMT cells. <i>Etv2</i> ^<i>+/-</i> mice spontaneously developed PH and right ventricular hypertrophy (RVH), associated with increased EndoMT markers and decreased EC markers.

BALB/c nude mice were used to establish xenograft models for inducing deep vein thrombosis. Tumor growth and thrombus length were assessed. The impact of DD on NET generation was analyzed using enzyme-linked immunosorbent assay, immunofluorescence staining, quantitative real-time PCR, and western blot analysis, both in vivo and in vitro. CI-amidine, a PAD4 inhibitor, was employed to evaluate the role of PAD4 in the generation of NETs. In vivo studies demonstrated that treatment with DD reduced tumor growth, inhibited thrombus formation, and decreased the levels of NET markers in the serum, tumor tissues, neutrophils, and thrombus tissues of mice. Additional data indicated that DD could suppress neutrophil counts, the release of tissue factor (TF), and the activation of thrombin-activated platelets, all of which contributed to increased formation of NETs in mouse models. In vitro, following incubation with conditioned medium (CM) derived from Lewis lung carcinoma cells, the expression of NET markers in neutrophils was significantly elevated, and an extracellular fibrous network structure was observed. Nevertheless, these NET-associated changes were partially counteracted by DD. Additionally, CI-amidine reduced the expression of NET markers in CM-treated neutrophils, consistent with the effects of DD. Collectively, DD inhibits cancer-associated thrombosis in lung cancer by decreasing PAD4-dependent NET formation through the regulation of TF-mediated thrombin-platelet activation.

Vascular endothelial growth factor (VEGF) and stromal cell-derived factor-1α (SDF) may help repair the dysfunctional endothelium and provide treatment for PAH. To examine this possibility, nanoparticles carrying human recombinant VEGF and SDF (VEGFNP and SDFNP) were aerosolized into the lungs of nude rats at Day 14 after monocrotaline (MCT) injection and analyses were performed at Day 28. The data show that the VEGFNP/SDFNP delivery led to a lower pulmonary arterial pressure and prevented right ventricular hypertrophy in the MCT rats: the right ventricular systolic pressure of the control, MCT, and MCT + VEGFNP/SDFNP treatment groups were 29±2, 70±9, and 44±5 (mean±SD) mmHg, respectively; the pulmonary vascular resistance indices of the groups were 0.6±0.3, 3.2±0.7, and 1.7±0.5, respectively; and the Fulton indices [-RV/(LV + Septum)] were 0.22±0.01, 0.44±0.07, and 0.23±0.02, respectively. The VEGFNP/SDFNP delivery delayed the thickening of distal pulmonary vessels: the number of nearly occluded vessels in a whole lung section from the MCT and MCT + VEGFNP/SDFNP groups were 46±12 and 2±3, respectively. Gene expression analysis of the endothelial cell markers, VE-cadherin, KDR, BMPR2, and eNOS, and smooth cell markers, SM-MHC and α-SMA, indicated significant loss of distal pulmonary vessels in the MCT- treated rats. VEGFNP/SDFNP delivery did not recover the loss, but significantly increased eNOS and decreased α-SMA expression in the MCT-treated lungs. Thus, the therapeutic effect of VEGFNP/SDFNP may be mediated by improving/repairing endothelial function in the PAH lungs.</p>","PeriodicalId":20927,"journal":{"name":"Pulmonary Circulation","volume":"14 4","pages":"e12412"},"PeriodicalIF":2.2,"publicationDate":"2024-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11459680/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142392842","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}

We reviewed CTEPH patients treated with BPA at our institution who had a transthoracic echocardiogram (TTE) before BPA and a follow-up TTE at any point during BPA. TAPSE was obtained from the initial and lattermost TTE; hemodynamics were obtained before each BPA session. Between March 2015 to October 2023, there were 228 patients treated with BPA. After excluding post-PTE patients and those without PH, 67 were included. Initial TAPSE/PASP was 0.39 ± 0.21 mm/mmHg. Using previously defined TAPSE/PASP tertiles in PH (<0.19, 0.19-0.32, >0.32 mm/mmHg), there were 6 patients (9%) in low, 30 (45%) in middle, and 31 (46%) in the high tertiles at baseline.

This systematic review evaluates miRNA expression changes in CTEPH and their direction. Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, we registered our protocol in International Prospective Register of Systematic Reviews (CRD42024524469). We included studies on miRNA expression in CTEPH with comparative or analytical designs, excluding nonhuman studies, interventions, non-English texts, conference abstracts, and editorials. Databases searched included PubMed, EMBASE, Scopus, CENTRAL, and ProQuest. The Quality Assessment of Diagnostic Accuracy Studies-2 tool assessed bias risk, and results were synthesized narratively. Of 313 unique studies, 39 full texts were reviewed, and 9 met inclusion criteria, totaling 235 participants. Blood samples were analysed using quantitative real time polymerase chain reaction. Seven miRNAs (miR-665, miR-3202, miR-382, miR-127, miR-664, miR-376c, miR-30) were uniformly upregulated, while nine (miR-20a-5p13, miR-17-5p, miR-93-5p, miR-22, let-7b, miR-106b-5p, miR-3148, miR-320-a, miR-320b) were downregulated in CTEPH patients.
