Abstract
Cardiovascular disease (CVD) stands as a predominant global cause of morbidity and mortality, necessitating effective and cost-efficient therapies for cardiovascular risk reduction. Mitochondrial coupling factor 6 (CF6), identified as a novel proatherogenic peptide, emerges as a significant risk factor in endothelial dysfunction development, correlating with CVD severity. CF6 expression can be heightened by CVD risk factors like mechanical force, hypoxia, or high glucose stimuli through the NF-κB pathway. Many studies have explored the CF6-CVD relationship, revealing elevated plasma CF6 levels in essential hypertension, atherosclerotic cardiovascular disease (ASCVD), stroke, and preeclampsia patients. CF6 acts as a vasoactive and proatherogenic peptide in CVD, inducing intracellular acidosis in vascular endothelial cells, inhibiting nitric oxide (NO) and prostacyclin generation, increasing blood pressure, and producing proatherogenic molecules, significantly contributing to CVD development. CF6 induces an imbalance in endothelium-dependent factors, including NO, prostacyclin, and asymmetric dimethylarginine (ADMA), promoting vasoconstriction, vascular remodeling, thrombosis, and insulin resistance, possibly via C-src Ca2+ and PRMT-1/DDAH-2-ADMA-NO pathways. This review offers a comprehensive exploration of CF6 in the context of CVD, providing mechanistic insights into its role in processes impacting CVD, with a focus on CF6 functions, intracellular signaling, and regulatory mechanisms in vascular endothelial cells.

Balloon pulmonary angioplasty for chronic thromboembolic pulmonary disease without pulmonary hypertension. Pulm Circ 2024; 14:e12409. [PMID: 38962183 PMCID: PMC11219285 DOI: 10.1002/pul2.12409] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/30/2024] [Revised: 05/28/2024] [Accepted: 06/22/2024] [Indexed: 07/05/2024] Open
Abstract
Balloon pulmonary angioplasty (BPA) is beneficial for patients with chronic thromboembolic pulmonary disease (CTEPD) with pulmonary hypertension (PH). However, the clinical benefit of BPA for the patients with CTEPD without PH remains unknown. In this study, we aimed to evaluate the efficacy, safety, and long-term outcomes of BPA in patients with CTEPD without PH. We retrospectively analyzed the data from 84 CTEPD patients with mean pulmonary artery pressure (mPAP) < 25 mmHg and 39 CTEPD patients with mPAP ≤ 20 mmHg (without PH). Among the 39 patients with CTEPD without PH, 14 underwent BPA (BPA-treated group), and the remaining 25 received no treatment (untreated group). In the patients with CTEPD without PH, BPA led to improvements in symptoms, pulmonary vascular resistance (3.6 ± 1.6 to 2.6 ± 1.1 Wood units, p < 0.001), peak oxygen consumption (16.1 ± 4.0 to 18.8 ± 4.3 mL/kg/min, p = 0.033), minute ventilation versus carbon dioxide production slope (41.4 ± 12.2 to 35.1 ± 6.7, p = 0.026), and mPAP/cardiac output slope (7.0 ± 2.6 to 4.4 ± 2.0 mmHg/L/min, p = 0.004) and facilitated the discontinuation of home oxygenation therapy, with no serious complications. Kaplan-Meier analysis showed no significant difference in all-cause mortality between the untreated and BPA-treated groups. BPA may be a safe treatment option for the patients with CTEPD without PH that can alleviate symptoms, improve exercise capacity, and facilitate weaning from home oxygen therapy. Further prospective randomized trials are needed to confirm these findings.

Chronic thromboembolic pulmonary hypertension: A comprehensive review of pathogenesis, diagnosis, and treatment strategies. Rev Port Cardiol 2024:S0870-2551(24)00187-2. [PMID: 38945473 DOI: 10.1016/j.repc.2024.04.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2023] [Revised: 04/09/2024] [Accepted: 04/17/2024] [Indexed: 07/02/2024] Open
Abstract
Chronic thromboembolic pulmonary hypertension (CTEPH) is part of group 4 of the pulmonary hypertension (PH) classification and generally affects more than a third of patients referred to PH centers. It is a three-compartment disease involving proximal (lobar-to-segmental) and distal (subsegmental) pulmonary arteries that are obstructed by persistent fibrothrombotic material, and precapillary pulmonary arteries that can be affected as in pulmonary arterial hypertension. It is a rare complication of pulmonary embolism (PE), with an incidence of around 3% in PE survivors. The observed incidence of CTEPH in the general population is around six cases per million but could be three times higher than this, as estimated from PE incidence. However, a previous venous thromboembolic episode is not always documented. With advances in multimodality imaging and therapeutic management, survival for CTEPH has improved for both operable and inoperable patients. Advanced imaging with pulmonary angiography helps distinguish proximal from distal obstructive disease. However, right heart catheterization is of utmost importance to establish the diagnosis and hemodynamic severity of PH. The therapeutic strategy relies on a stepwise approach, starting with an operability assessment. Pulmonary endarterectomy (PEA), also known as pulmonary thromboendarterectomy, is the first-line treatment for operable patients. Growing experience and advances in surgical technique have enabled expansion of the distal limits of PEA and significant improvements in perioperative and mid- to long-term mortality. In patients who are inoperable or who have persistent/recurrent PH after PEA, medical therapy and/or balloon pulmonary angioplasty (BPA) are effective treatment options with favorable outcomes that are increasingly used. All treatment decisions should be made with a multidisciplinary team that includes a PEA surgeon, a BPA expert, and a chest radiologist.

[PMID: 38128770 DOI: 10.1016/j.healun.2023.12.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2023] [Revised: 11/17/2023] [Accepted: 12/12/2023] [Indexed: 12/23/2023] Open
Abstract
BACKGROUND Balloon pulmonary angioplasty improves the hemodynamics of patients with inoperable chronic thromboembolic pulmonary hypertension; however, the clinical impact of recurrent pulmonary hypertension after balloon pulmonary angioplasty remains unclear. METHODS We retrospectively reviewed 262 consecutive patients with chronic thromboembolic pulmonary hypertension who underwent balloon pulmonary angioplasty between July 2009 and December 2020; 158 (65 ± 12 years; males, 20%; median follow-up period, 45 [26, 66] months) with follow-up right heart catheterization and no residual pulmonary hypertension were included. Recurrent pulmonary hypertension was defined as mean pulmonary arterial pressure <25 mm Hg at the first evaluation after balloon pulmonary angioplasty and ≥25 mm Hg at follow-up evaluation requiring additional treatment with balloon pulmonary angioplasty or pulmonary vasodilators. RESULTS Recurrent pulmonary hypertension was observed in 11 patients; the state occupation probability of recurrence at 5 years was 9.0% (95% confidence interval: 5.0%-18.9%). Only 1 case (0.6%) of recurrent pulmonary hypertension showed vascular restenosis and reocclusion of previously treated lesions, with more significant hemodynamic and exercise capacity deterioration than the other cases. Additional treatments for recurrent pulmonary hypertension (balloon pulmonary angioplasty in 9 patients, pulmonary vasodilators in 4 patients) improved the mean pulmonary arterial pressure from 27 [26, 29] to 22 [19, 23] mm Hg (p < 0.01). Recurrence had a low probability of transitioning to death in an illness-death model. No specific risk factors for recurrent pulmonary hypertension were identified. CONCLUSIONS Symptomatic recurrent pulmonary hypertension due to vascular restenosis or reocclusion after balloon pulmonary angioplasty was extremely rare. Most cases of recurrent pulmonary hypertension were mild, did not worsen clinically, and had favorable prognoses.

Abstract
Advances in the treatment of chronic thromboembolic pulmonary hypertension (CTEPH) over the past decade changed the disease landscape, yet global insight on clinical practices remains limited. The CTEPH global cross-sectional scientific survey (CLARITY) aimed to gather information on the current diagnosis, treatment, and management of CTEPH and to identify unmet medical needs. This paper focuses on the treatment and management of CTEPH patients. The survey was circulated to hospital-based medical specialists through Scientific Societies and other medical organizations from September 2021 to May 2022. The majority of the 212 respondents involved in the treatment of CTEPH were from centers performing up to 50 pulmonary endarterectomy (PEA) and/or balloon pulmonary angioplasty (BPA) procedures per year. Variation was observed in the reported proportion of patients deemed eligible for PEA/BPA, as well as those that underwent the procedures, including multimodal treatment and subsequent follow-up practices. Prescription of pulmonary arterial hypertension-specific therapy was reported for a variable proportion of patients in the preoperative setting and in most nonoperable patients. Reported use of vitamin K antagonists and direct oral anticoagulants was similar (86% vs. 82%) but driven by different factors. This study presents heterogeneity in treatment approaches for CTEPH, which may be attributed to center-specific experience and region-specific barriers to care, highlighting the need for new clinical and cohort studies, comprehensive clinical guidelines, and continued education.

Abstract
Pulmonary arterial hypertension (PAH) is a severe cardiopulmonary disorder with complex causes. Calcium channel blockers have long been used in its treatment. Our study aimed to validate experimental results showing increased calcium ion concentration in PAH patients. We investigated the impact of genes related to calcium channel regulation on PAH development and developed an accurate diagnostic model. Clinical trial data from serum of 18 healthy individuals and 18 patients with PAH were retrospectively analyzed. Concentrations of calcium and potassium ions were determined and compared. Datasets were retrieved, selecting genes associated with calcium ion release. R packages processed the datasets, filtering 174 common genes, and conducting Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analyses. Six hub genes were identified, and nomogram and logistic regression prediction models were constructed. Random forest filtered cross genes, and a diagnostic model was developed and validated using an artificial neural network. The 174 intersection genes related to calcium ions showed significant correlations with biological processes, cellular components, and molecular functions. Six key genes were obtained by constructing a protein-protein interaction network. A diagnostic model with high accuracy (> 90%) and diagnostic capability (AUC = 0.98) was established using a neural network algorithm. This study validated the experimental results, identified key genes associated with calcium ions, and developed a highly accurate diagnostic model using a neural network algorithm. These findings provide insights into the role of calcium release genes in PAH and demonstrate the potential of the diagnostic model for clinical application. However, due to limitations in sample size and a lack of prognosis data, the regulatory mechanisms of calcium ions in PAH patients and their impact on the clinical prognosis of PAH patients still need further exploration in the future.

Performance-based outcome measures for assessing physical capacity in patients with pulmonary embolism: A scoping review. Thromb Res 2024; 235:52-67. [PMID: 38301376 DOI: 10.1016/j.thromres.2024.01.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2023] [Revised: 12/22/2023] [Accepted: 01/10/2024] [Indexed: 02/03/2024]
Abstract
INTRODUCTION Up to 50 % of patients surviving a pulmonary embolism (PE) report persisting shortness of breath, reduced physical capacity and psychological distress. As the PE population is heterogeneous compared to other cardiovascular patient groups, outcome measures for assessing physical capacity traditionally used in cardiac populations may not be reliable for the PE population as a whole. This scoping review aims to 1) map performance-based outcome measures (PBOMs) used for assessing physical capacity in PE research, and 2) to report the psychometric properties of the identified PBOMs in a PE population. METHODS The review was conducted according to the Joanna Briggs Institute framework for scoping reviews and reported according to the PRISMA-Extension for Scoping Reviews guideline. RESULTS The systematic search of five databases identified 4585 studies, of which 243 studies met the inclusion criteria. Of these, 185 studies focused on a subgroup of patients with chronic thromboembolic pulmonary hypertension. Ten different PBOMs were identified in the included studies. The 6-minute walk test (6MWT) and cardiopulmonary exercise test (CPET) were the most commonly used, followed by the (Modified) Bruce protocol and Incremental Shuttle Walk test. No studies reported psychometric properties of any of the identified PBOMs in a PE population. CONCLUSIONS Publication of studies measuring physical capacity within PE populations has increased significantly over the past 5-10 years. Still, not one study was identified, reporting the validity, reliability, or responsiveness for any of the identified PBOMs in a PE population. This should be a priority for future research in the field.

Abstract
BACKGROUND The maintenance dosage of selexipag is categorized as low, medium or high. In order to assess the efficacy and safety of different dosages of selexipag for the risk stratification of pulmonary arterial hypertension (PAH), we performed a systematic review and meta-analysis. METHODS Studies assessing PAH risk stratification indices, such as the World Health Organization functional class (WHO-FC), six-minute walk distance (6MWD), N-terminal pro-B-type natriuretic peptide (NT-proBNP) level, right atrial pressure (RAP), cardiac index (CI) and mixed venous oxygen saturation (SvO2), were included. RESULTS Thirteen studies were included. Selexipag led to improvements in the 6MWD (MD: 24.20 m, 95% CI: 10.74-37.67), NT-proBNP (SMD: -0.41, 95% CI: -0.79-0.04), CI (MD: 0.47 L/min/m2, 95% CI: 0.17-0.77) and WHO-FC (OR: 0.564, 95% CI: 0.457-0.697). Subgroup analysis demonstrated that all three dosages improved the 6MWD. A moderate dosage led to improvements in the CI (MD: 0.30 L/min/m2, 95% CI: 0.15-0.46) and WHO-FC (OR: 0.589, 95% CI: 0.376-0.922). Within 6 months of treatment, only the WHO-FC and CI were significantly improved (OR: 0.614, 95% CI: 0.380-0.993; MD: 0.30 L/min/m2, 95% CI: 0.16-0.45, respectively). More than 6 months of treatment significantly improved the 6MWD, WHO-FC and NT-proBNP (MD: 40.87 m, 95% CI: 10.97-70.77; OR: 0.557, 95% CI: 0.440-0.705; SMD: -0.61, 95% CI: -1.17-0.05, respectively). CONCLUSIONS Low, medium, and high dosages of selexipag all exhibited good effects. When treatment lasted for more than 6 months, selexipag exerted obvious effects, even in the low-dosage group. This finding is important for guiding individualized treatments.

Abstract
Pulmonary hypertension (PH) is defined as elevated pressures in the pulmonary artery and is associated with significant morbidity and mortality. The World Health Organization classifies PH into 5 distinct groups based on underlying etiology, pathology, and modality of treatment. Therapeutic approach may be challenging due to the extensive spectrum of causes and underlying mechanisms mediating PH. The 5 groups include pulmonary arterial hypertension (group 1), PH secondary to left heart disease (group 2), PH secondary to chronic lung disease (group 3), chronic thromboembolic pulmonary hypertension (group 4), and PH due to miscellaneous causes (group 5). Although significant progress has been made in the treatment of group 1 PH, there is a continued need to develop new therapies for all types of PH. Additionally, most treatments currently available improve functional capacity and symptoms but without a significant benefit in mortality. In this review, we aim to describe the various etiologies of PH and their established pharmacotherapies, as well as expand on emerging therapeutic options for each group.

Prognostic implication of glomerular filtration rates in patients with chronic thromboembolic pulmonary hypertension who have undergone balloon pulmonary angioplasty. Exp Ther Med 2024; 27:18.

Abstract
Chronic thromboembolic pulmonary hypertension (CTEPH) plays a key role in the deterioration of lung hemodynamics and contributes to secondary dysfunction of the right heart, which is consistently accompanied by systemic malperfusion and a reduced glomerular filtration rate (GFR). The prognosis of CTEPH is markedly influenced by renal function. The aim of the present study was to evaluate the prognostic value of GFR in patients with CTEPH who have undergone balloon pulmonary angioplasty (BPA). From December 2012 to September 2020, a total of 47 patients diagnosed with CTEPH who received BPA were retrospectively studied. Patients were categorized according to their renal function on admission into two groups: GFR >53 and ≤53. Biological, clinical and demographic data of the patients were collected. Data for the two groups in hospital and during follow-up were systematically analyzed and compared. All-cause mortality, death from right heart failure (RHF) and rehospitalization associated with RHF were considered major adverse events (MAEs). The results revealed that the 6-min walk distance, N-terminal pro-B type natriuretic peptide (NT-proBNP), Troponin I and right ventricle diameter were significantly lower, and tricuspid annular plane systolic excursion was significantly higher in the GFR >53 group compared with the GFR ≤53 group at final follow-up. In addition, GFR levels were significantly correlated with NT-proBNP at baseline and final follow-up. Furthermore, based on a multivariate analysis, it was determined that the decreased GFR was an independent predictor of MAEs during follow-up. Therefore, it may be concluded that in addition to being associated with right ventricular function, decreased GFR is also a prognostic marker in CTEPH treated with BPA.

Abstract
Chronic thromboembolic pulmonary hypertension is rare, underdiagnosed form of pulmonary hypertension. It is caused by intravascular obstruction of pulmonary arteries due to fibrotic transformation of thromboembolic material and microvasculopathy. It is important to diagnose this variant as potentially curative treatment in the form of pulmonary endarterectomy is available. Last two decades have seen rapid advances in targeted medical management and refinement in balloon pulmonary angioplasty technique, which have provided a viable therapeutic option for patients who deemed to be inoperable.

Abstract
Chronic thromboembolic pulmonary hypertension (CTEPH) is designated as an intractable disease by the Ministry of Health, Labour and Welfare of Japan, and has an extremely poor prognosis if untreated. Surgical pulmonary endarterectomy is the curative treatment for cases in which the organized thrombi are located in the central part of the pulmonary artery, but there had been no effective treatment for cases in which the thrombi are located in the peripheral part of the pulmonary artery. Recently, balloon pulmonary angioplasty (BPA), a transcatheter procedure to dilate stenotic or occluded lesions in the peripheral pulmonary artery, has been rapidly developed. Although BPA was once a globally abandoned procedure due to hemorrhagic complications, Japanese experts have improved the technique, and its safety and efficacy have been enhanced. As a result, BPA is now being reevaluated worldwide. This review describes the history and development of BPA in the treatment of CTEPH, as well as the status of this treatment in Fukushima Prefecture.

Abstract
Chronic thromboembolic pulmonary hypertension (CTEPH) is caused by persistent organized thromboembolic obstruction of the pulmonary arteries from incompletely resolved pulmonary embolism. The treatment of choice is pulmonary thromboendarterectomy (PTE) surgery and all patients should be evaluated for operability candidacy. Despite advancements in PTE technique allowing more segmental-subsegmental surgeries, up to a third of patients with CTEPH may still be considered inoperable. Over the past decade, there have been increasing treatment options for these inoperable CTEPH patients. Balloon pulmonary angioplasty (BPA) is a percutaneous-based interventional treatment option for select CTEPH cases. Early BPA experiences were plagued by high complication rates, but further refinements in technique and equipment pioneered by Japan led to the worldwide spread and adoption of BPA. Multiple centers have shown that patients experience significant improvements in hemodynamics, quality of life, exercise capacity, and survival with BPA treatment. There remain many questions on best practices, but BPA has evolved into a pivotal cornerstone of CTEPH treatment.

Abstract
Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare complication of acute pulmonary embolism. Important advances have enabled better understanding, characterisation, and treatment of this condition. Guidelines recommending systematic follow-up after acute pulmonary embolism, and the insight that CTEPH can mimic acute pulmonary embolism on initial presentation, have led to the definition of CTEPH imaging characteristics, the introduction of artificial intelligence diagnosis pathways, and thus the prospect of easier and earlier CTEPH diagnosis. In this Series paper, we show how the understanding of CTEPH as a sequela of inflammatory thrombosis has driven successful multidisciplinary management that integrates surgical, interventional, and medical treatments. We provide imaging examples of classical major vessel targets, describe microvascular targets, define available tools, and depict an algorithm facilitating the initial treatment strategy in people with newly diagnosed CTEPH based on a multidisciplinary team discussion at a CTEPH centre. Further work is needed to optimise the use and combination of multimodal therapeutic options in CTEPH to improve long-term outcomes for patients.

Abstract
Chronic thromboembolic pulmonary hypertension (CTEPH) is a treatable form of pulmonary hypertension and right heart failure. CTEPH (group 4 pulmonary hypertension) is caused by persistent organized thromboembolic obstruction of the pulmonary arteries from incompletely resolved acute pulmonary embolism. CTEPH also may present without prior VTE history, which can contribute to its underrecognition. The true incidence of CTEPH is unclear, but is estimated to be approximately 3% after acute pulmonary embolism. V˙/Q˙ scintigraphy is the best screening test for CTEPH, with CT scan imaging and other advanced imaging methods now playing a larger role in disease detection and confirmation. Perfusion defects on V˙/Q˙ scintigraphy in the setting of pulmonary hypertension are suggestive of CTEPH, but pulmonary angiography and right heart catheterization are required for confirmation and treatment planning. CTEPH potentially is curative with pulmonary thromboendarterectomy surgery, with mortality rates of approximately 2% at expert centers. Advances in operative techniques are allowing more distal endarterectomies to be performed successfully with favorable outcomes. However, more than one-third of patients may be considered inoperable. Although these patients previously had minimal therapeutic options, effective treatments now are available with pharmacotherapy and balloon pulmonary angioplasty. Diagnosis of CTEPH should be considered in all patients with suspicion of pulmonary hypertension. Treatments for CTEPH have advanced with improvements in outcomes for both operable and inoperable patients. Therapy should be tailored based on multidisciplinary team evaluation to ensure optimal treatment response.

Abstract
Chronic thromboembolic pulmonary hypertension (CTEPH) is a late complication of acute pulmonary thromboembolism owing to incomplete clot dissolution in pulmonary artery. Pulmonary endarterectomy is the first-line treatment for CTEPH. However, 40% of patients are not candidates for surgery because of distal lesions or age. Balloon pulmonary angioplasty (BPA), a catheter-based intervention, is increasingly being used worldwide for treating inoperable CTEPH. Previous BPA strategy had a major concern of reperfusion pulmonary edema as a complication. However, recent refined strategies promise safe and effective BPA. Five-year survival rate after BPA is 90% for inoperable CTEPH, comparable with that of operable CTEPH.

Abstract
INTRODUCTION Chronic thromboembolic pulmonary hypertension (CTEPH) is a progressive and debilitating disorder that results from incomplete resolution of vascular obstructions resulting in pulmonary hypertension. Surgical pulmonary thromboendarterectomy (PTE) is the treatment of choice for CTEPH. Unfortunately, many CTEPH patients are ineligible for PTE or do not have access to an expert surgical center. Medical therapy imparts important symptomatic and exercise benefits for CTEPH patients, but it does not extend survival. Balloon pulmonary angioplasty (BPA) is an emerging transcatheter approach that is both safe and efficacious. However, the potential synergy between upfront BPA and medical therapy treatment approaches in patients with inoperable CTEPH is unknown. Here, we evaluated how the combination of BPA and medical therapy compared to medical therapy alone in a newly established BPA program. METHODS Twenty-one patients with inoperable or residual CTEPH were evaluated in this single-center observational study. Ten patients underwent upfront BPA and medical therapy while 11 patients were treated with medical therapy alone. Hemodynamic and echocardiographic assessments were performed at baseline and at least 1 month after completion of therapy. Continuous variables were compared using t-test or Mann-Whitney U-test. Categorical variables were analyzed with Chi squared and Fisher's exact test where appropriate. RESULTS Combination therapy significantly reduced mean pulmonary arterial pressure (mPAP) and pulmonary vascular resistance (PVR), but medical therapy only significantly lowered PVR. Comprehensive echocardiographic analysis revealed a more robust reverse right ventricular (RV) remodeling effect and augmentation of RV function with combination therapy. At the end of study, the combination therapy group had lower mPAP and PVR and better RV function. Importantly, there were no significant adverse effects in patients treated with BPA. CONCLUSION Combination therapy significantly improves hemodynamics and RV function in inoperable CTEPH while carrying an acceptable risk profile, even in a newly developed program. Further studies comparing upfront combination therapy to medical therapy with larger, long-term, and randomized approaches should be considered.

Abstract
Pulmonary arterial hypertension (PAH) is a malignant pulmonary vascular syndrome characterized by a progressive increase in pulmonary vascular resistance and pulmonary arterial pressure, which eventually leads to right heart failure and even death. Although the exact mechanism of PAH is not fully understood, pulmonary vasoconstriction, vascular remodeling, immune and inflammatory responses, and thrombosis are thought to be involved in the development and progression of PAH. In the era of non-targeted agents, PAH had a very dismal prognosis with a median survival time of only 2.8 years. With the deep understanding of the pathophysiological mechanism of PAH as well as advances in drug research, PAH-specific therapeutic drugs have developed rapidly in the past 30 years, but they primarily focus on the three classical signaling pathways, namely the endothelin pathway, nitric oxide pathway, and prostacyclin pathway. These drugs dramatically improved pulmonary hemodynamics, cardiac function, exercise tolerance, quality of life, and prognosis in PAH patients, but could only reduce pulmonary arterial pressure and right ventricular afterload to a limited extent. Current targeted agents delay the progression of PAH but cannot fundamentally reverse pulmonary vascular remodeling. Through unremitting efforts, new therapeutic drugs such as sotatercept have emerged, injecting new vitality into this field. This review comprehensively summarizes the general treatments for PAH, including inotropes and vasopressors, diuretics, anticoagulants, general vasodilators, and anemia management. Additionally, this review elaborates the pharmacological properties and recent research progress of twelve specific drugs targeting three classical signaling pathways, as well as dual-, sequential triple-, and initial triple-therapy strategies based on the aforementioned targeted agents. More crucially, the search for novel therapeutic targets for PAH has never stopped, with great progress in recent years, and this review outlines the potential PAH therapeutic agents currently in the exploratory stage to provide new directions for the treatment of PAH and improve the long-term prognosis of PAH patients.

Abstract
Chronic thromboembolic pulmonary hypertension (CTEPH) is a group 4 pulmonary hypertension (PH) characterized by nonresolving thromboembolism in the central pulmonary artery and vascular occlusion in the proximal and distal pulmonary artery. Medical therapy is chosen for patients who are ineligible for pulmonary endarterectomy or balloon pulmonary angioplasty or who have symptomatic residual PH after surgery or intervention. Selexipag, an oral prostacyclin receptor agonist and potent vasodilator, was approved for CTEPH in Japan in 2021. To evaluate the pharmacological effect of selexipag on vascular occlusion in CTEPH, we examined how its active metabolite MRE-269 affects platelet-derived growth factor-stimulated pulmonary arterial smooth muscle cells (PASMCs) from CTEPH patients. MRE-269 showed a more potent antiproliferative effect on PASMCs from CTEPH patients than on those from normal subjects. DNA-binding protein inhibitor (ID) genes ID1 and ID3 were found by RNA sequencing and real-time quantitative polymerase chain reaction to be expressed at lower levels in PASMCs from CTEPH patients than in those from normal subjects and were upregulated by MRE-269 treatment. ID1 and ID3 upregulation by MRE-269 was blocked by co-incubation with a prostacyclin receptor antagonist, and ID1 knockdown by small interfering RNA transfection attenuated the antiproliferative effect of MRE-269. ID signaling may be involved in the antiproliferative effect of MRE-269 on PASMCs. This is the first study to demonstrate the pharmacological effects on PASMCs from CTEPH patients of a drug approved for the treatment of CTEPH. Both the vasodilatory and the antiproliferative effect of MRE-269 may contribute to the efficacy of selexipag in CTEPH.

Impact of residual pulmonary hypertension on long-term outcomes after pulmonary endarterectomy in the modern era. Pulm Circ 2023; 13:e12215. [PMID: 37051490 PMCID: PMC10084236 DOI: 10.1002/pul2.12215] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/27/2022] [Revised: 03/15/2023] [Accepted: 03/25/2023] [Indexed: 04/14/2023] Open
Abstract
Residual pulmonary hypertension (PH) negatively impacts long-term results following pulmonary endarterectomy (PEA) for chronic thromboembolic pulmonary hypertension (CTEPH). We sought to reveal whether modern PH therapy with PH-targeted medicine and balloon pulmonary angioplasty (BPA) improved long-term results of residual PH after PEA. Long-term findings of 80 patients who survived PEA between 2011 and 2019 were retrospectively investigated. One month after PEA, 30 patients developed residual PH defined as mean pulmonary artery pressure (mPAP) ≥25 mmHg, of whom 23 were treated by PH-targeted medicine and 9 by BPA. Patients with residual PH acquired considerably better functional status and exercise capacity after PEA, however, exhibited significantly worse survival rates than those without. Eleven patients died during follow-up: 8 patients with residual PH and 3 controls. Among patients with residual PH, the deceased had a significantly lower %decrease in mPAP from 1 month to 1 year following PEA (7.4 [-32.6 to 8.0] % vs. 10.4 [3.7-27.8] %, p = 0.03) and higher mPAP at 1 year following PEA (39.5 [33.25-42.5] vs. 27 [26-34] mmHg, p < 0.01) despite PH-targeted medicine than the survived. No patients passed away from right heart failure, and there was no difference between the groups in CTEPH-related mortality. Modern PH therapy was used to address the majority of residual PH. Long-term survival after PEA was negatively impacted by residual PH, but it appeared that long-term mortality was also correlated with unrelieved residual PH despite PH-targeted medicine. Modern PH therapy may have enhanced functional status and excercise capacity, and averted fatal right heart failure.

Surgical and Device Interventions in the Treatment of Chronic Thromboembolic Disease. Pulm Ther 2023; 9:207-221.

Abstract
Chronic thromboembolic pulmonary disease (CTEPD) is characterized by unresolved clot burden in large pulmonary arteries, obstructive disease in smaller arteries, and increased downstream clot burden. This occurs in the setting of abnormal fibrinolysis or hematological disorders. Up to 50% of patients in some studies are unaware of a self-history of a deep venous thrombosis or pulmonary embolism. Ultimately, they present with symptoms of pulmonary hypertension (PH), which can result in right heart failure (RHF). Pulmonary endarterectomy (PEA) is curative, though many patients have prohibitive surgical risk or surgically inaccessible disease, warranting other interventions such as balloon pulmonary angioplasty (BPA) and medical therapy. Rarely, other treatment options may be implemented. We focus this review on PEA and BPA, with an overview of the history of CTEPD and the evolution of these procedures. We will briefly discuss other treatment modalities.

Efficacy and safety of non-prostanoid prostacyclin receptor agonist for pulmonary hypertension: A meta-analysis. Pulm Pharmacol Ther 2023; 78:102182. [PMID: 36460268 DOI: 10.1016/j.pupt.2022.102182] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/22/2022] [Revised: 11/20/2022] [Accepted: 11/28/2022] [Indexed: 12/02/2022]
Abstract
BACKGROUND Oral non-prostanoid prostacyclin receptor agonists therapies have been recommended for pulmonary arterial hypertension in many countries. OBJECTIVE We aimed to evaluate the specific impact of non-prostanoid prostacyclin receptor agonists on pulmonary hypertension and to explore the influence of study characteristics on results. METHODS PubMed, Embase, and ClinicalTrials.gov were systematically searched from inception to July 12, 2022. Randomized controlled trials comparing non-prostanoid prostacyclin receptor agonists administration with placebo for treating pulmonary hypertension were included. Two researchers independently selected eligible studies, assessed the bias risk and extracted related data. RevMan5.1 was used for performing the statistical analysis and the assessment of bias risk of the enrolled studies. PROSPERO registered number CRD42022304172. RESULTS Seven trials involving 1727 patients were included. Pooled analyses indicated non-prostanoid prostacyclin receptor agonists significantly reduced clinical worsening events (risk ratio [RR], 0.63; 95% confidence interval [CI], 0.54 to 0.74), increased 6-min walk distance (mean difference [MD], 10 m; 95% CI, 3-17 m), decreased pulmonary vascular resistance (MD, -121 dyn s/cm5; 95% CI, -172 to -69 dyn s/cm5) and increased cardiac index (MD, 0.38 L/min/m2; 95% CI, 0.26-0.50 L/min/m2) compared with the control. No significant differences in all-cause mortality (RR, 0.86; 95% CI, 0.26 to 2.78), NYHA/WHO functional class (RR, 1.16; 95% CI, 0.61 to 2.18), mean pulmonary artery pressure (MD, -0.88 mmHg; 95% CI, -2.20 to 0.44 mmHg), right atrial pressure (MD, 0.66 mmHg; 95% CI, -0.59 to 1.90 mmHg) and total adverse events (RR, 1.05; 95% CI, 0.99 to 1.10) were found between non-prostanoid prostacyclin receptor agonists group and control group. CONCLUSION Non-prostanoid prostacyclin receptor agonists treatment exerted benefits on clinical worsening, pulmonary vascular resistance, and cardiac index in pulmonary hypertension patients, without increasing the incidence of total adverse events.

Abstract
A 77-year-old man presented with dyspnoea and was diagnosed with chronic thromboembolic pulmonary hypertension. Balloon pulmonary angioplasty was attempted; however, the balloons could not be advanced to the total occlusion lesion in the right A3 segment. The obstruction was overcome using a microcatheter Corsair (AsahiKASEI). This technique may be useful in managing a total occlusion lesion.

Efficacy and safety of guide extension catheter in balloon pulmonary angioplasty for treatment of complex lesions in chronic thromboembolic pulmonary hypertension. PLoS One 2023; 18:e0280683. [PMID: 36706099 PMCID: PMC9882884 DOI: 10.1371/journal.pone.0280683] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2022] [Accepted: 01/05/2023] [Indexed: 01/28/2023] Open
Abstract
BACKGROUND Balloon pulmonary angioplasty (BPA) is used for treatment of inoperable chronic thromboembolic pulmonary hypertension (CTEPH) and residual pulmonary hypertension after pulmonary endarterectomy (PEA) to improve hemodynamics, right ventricular function, and exercise capacity. However, the effectiveness and safety of guide extension catheters for BPA treatment in patients with CTEPH have not been demonstrated. METHODS We retrospectively analyzed 91 lesions in 55 sessions of 28 patients with CTEPH who underwent BPA using a guide extension catheter. The purpose (backup, coaxial, and extension), efficacy, and safety of the guide extension catheters were explored. The efficacy of the guide extension catheter was assessed based on the success of the procedures and safety was evaluated based on procedure-related complications. RESULTS Regarding the intended use, a guide extension catheter was used to strengthen the backup force of the guiding catheter in 52% of cases, extend the tip of the catheter in 38% of cases, and maintain the coaxiality of the guiding catheter in 10% of cases. Procedural success was achieved in 92.7% of 55 sessions and in 95.6% of 91 lesions. Complex lesions had a lower success rate than simple lesions (p = 0.04). Regarding safety concerns, complications were observed in 5 of 55 sessions (9.1%) and 6 of 91 lesions (6.6%). Only one case of pulmonary artery dissection using a guide extension catheter was reported. Except for this one case, extension catheter-related complications were not observed. CONCLUSIONS A guide extension catheter can be used safely in BPA procedures with anatomically complex pulmonary artery branches and complex lesions by increasing backup support.
