Demographic and hemodynamic data from patients with idiopathic pulmonary arterial hypertension (IPAH) and chronic thromboembolic pulmonary hypertension (CTEPH) have not been systematically characterized to identify differences related to gender, age, race, disease severity, and drug response. Our goal was to define the distribution and relation of IPAH and CTEPH based on these criteria. Hemodynamic and demographic data from 242 IPAH patients and 90 CTEPH patients were collected and compared. IPAH incidence was greater in women, but men had a higher basal mean pulmonary arterial pressure (mPAP). mPAP was comparable among all IPAH ethnic groups. IPAH patients with no history of fenfluramine-phentermine use had a higher mPAP than users. Exercise-induced IPAH was apparent in 14.5% of IPAH patients. Only 9% of IPAH patients responded to inhaled nitric oxide with a ≥20% decrease in mPAP. Compared to CTEPH patients, mPAP was greater but average age of diagnosis was lower in IPAH patients. mPAP negatively correlated with age of diagnosis in IPAH patients only. These results indicate that elevated CO is not the main determinant of mPAP in both IPAH and CTEPH patients. However, the two patient groups differ in terms of their demographic and hemodynamic distributions, and according to the correlation between mPAP and other clinical hemodynamics and demographics.

Hemodynamic responder status defined as an acute decrease of mean pulmonary arterial pressure (mPAP)>10mmHg and below 40mmHg is associated with improved outcome in patients (pts) with pulmonary arterial hypertension (PAH). Pulmonary vascular reactivity to nitric oxide (NO) is controversial in chronic thromboembolic pulmonary hypertension (CTEPH). We speculated that the magnitude of the acute decrease in mean pulmonary artery pressure (mPAP) after exposure to NO might reflect the degree of small vessel disease in CTEPH and thus, affect long-term outcome. Methods: Right heart catheterization was performed in 62 (55  ± 15 years, 32 female) pts with major-vessel CTEPH, at baseline and during inhalation of 40ppm NO. Within 25±15 days patients underwent pulmonary endarterectomy (PEA). Pts were followed for 11.3±26 months. Predictors of survival were analyzed by Cox regression analysis, and survival was described by Kaplan-Meier curves. Results: Significant reductions in mean pulmonary arterial pressure (mPAP; p<0.001), pulmonary vascular resistance (PVR; p<0.001) and an increase in mixed venous oxygen saturation following NO inhalation were demonstrated (p<0.001) by a paired t-test. Stepwise multivariate analysis revealed the relative change of PVR after NO inhalation as a predictor of survival. Patients whose PVR during NO inhalation declined below 789.8 dynes.s.cm-5 had significantly better outcome than patients with above median PVR. There was a strong negative correlation between the relative change of PVR under NO and recurrent pulmonary hypertension after PEA (p=0.02). Conclusions: Patients with operable CTEPH demonstrated acute pulmonary vascular reactivity, mostly not corresponding to a complete responder status, but accounting for a wide range of decreases of mPAP [change of mPAP (%) (−10.9±14)] and PVR [change of PVR (%) (−17 ±15)]. Reduction of PVR under 800 dynes.s.cm-5 after inhalation of NO was associated with better outcome. Responsiveness to inhaled nitric oxide is a predictor for mid-term survival in adult patients with CTEPH undergoing PEA.

Aim: to perform the complex analysis of clinical, functional, hemodynamics profile in patients with inoperable chronic thromboembolic pulmonary hypertension (CTEPH) compared to the idiopathic pulmonary arterial hypertension (IPAH) group at the time of diagnosis verification according to the Russian registry, and to evaluate the features of medical therapy and it’s influence on prognosis in these patients. Materials and methods. In the retrospective study 193 patients with IPAH and 130 patients with inoperable CTEPH older than 18 years were included. All included patients were the participants of Russian registry (www.medibase.pro) in 15 Russian expert centers during the period from 01.01.2012 to 31.12.2018 year. The diagnosis was verified according to the algorithm, reflected in the Russian guidelines on diagnosis and treatment of PH and CTEPH (2016 year). The comparison analysis of clinical, functional, hemodynamics parameters in patients with IPAH and inoperable CTEPH was made. Results. The status of 193 patients with IPAH (32 male and 162 female) and 130 patients with inoperable CTEPH - (40 male and 90 female) was analyzed during the study. The CTEPH patients were older compared to the IPAH patients: 52.2 [41.1; 60.6] and 36.5 [26.8; 36.5] years, respectively. The median period since symptom occurrence till CTEPH verification was 1.08 [0.2; 3.1] years, in IPAH patients - 2.01 [0.6; 4.2] years. More than 80% of inoperable CTEPH patients had III and IV functional class (FC) according to the World Health Organization classification at the time of diagnosis verification versus 61% of IPAH patients. According to echocardiography the level of mean pulmonary arterial pressure was comparable in two groups of PH patients. However in inoperable CTEPH patients the right atrial area was larger. The significantly higher value of mean pulmonary arterial pressure and lower value oxygen saturation of arterial blood according to the right heart catheterization were revealed. The 5-year survival in CTEPH patients, receiving initial dual combination therapy in 75% cases (in 40% - combination of riociguat and iloprost ) was 93% versus 86.5% in patients with IPAH. Conclusion: It was revealed, that inoperable CTEPH patients were significantly older with severe functional and hemodynamics status at the time of diagnosis verification, although with higher level of 5-year survival compared to the IPAH patients according to the Russian registry.

Background Although chronic thromboembolic pulmonary hypertension (CTEPH) and acute pulmonary embolism (APE) share some clinical manifestations, a limited proportion of patients with CTEPH have a history of APE. Moreover, in histopathologic studies, it has been revealed that pulmonary vasculature lesions similar to pulmonary arterial hypertension existed in patients with CTEPH. Thus, it remains unknown whether these 3 disorders also share genetic backgrounds. Methods and Results Whole exome screening was performed with DNA isolated from 51 unrelated patients with CTEPH of Japanese ancestry. The frequency of genetic variants associated with pulmonary arterial hypertension or APE in patients with CTEPH was compared with those in the integrative Japanese Genome Variation Database 3.5KJPN. Whole exome screening analysis showed 17 049 nonsynonymous variants in patients with CTEPH. Although we found 6 nonsynonymous variants that are associated with APE in patients with CTEPH, there was no nonsynonymous variant associated with pulmonary arterial hypertension. Patients with CTEPH with a history of APE had nonsynonymous variants of F5 , which encodes factor V. In contrast, patients with CTEPH without a history of APE had a nonsynonymous variant of THBD , which encodes thrombomodulin. Moreover, thrombin‐activatable fibrinolysis inhibitor, which is one of the pathogenic proteins in CTEPH, was significantly more activated in those who had the variants of THBD compared with those without it. Conclusions These results provide the first evidence that patients with CTEPH have some variants associated with APE, regardless of the presence or absence of a history of APE. Furthermore, the variants might be different between patients with CTEPH with and without a history of APE.

Chronic Thromboembolic Pulmonary Hypertension (CTEPH) is a rare disease with poor prognosis if left untreated, characterized by pulmonary vascular bed obstruction due to unresolving thromboembolic material. The Hellenic pulmonary hypertension registry (HOPE) was launched in Greece in early 2015 and enrolls patients from all pulmonary hypertension subgroups in Greece. In total, 98 patients with CTEPH were enrolled from January 2015 until November 2019. Of these patients, 55.1% represented incident population, 50% were classified in the World Health Organization functional class II and 49% had a history of acute pulmonary embolism. The median values of pulmonary vascular resistance (PVR) and cardiac index were 7.4 (4.8) WU and 2.4 (1.0) L/min/m2, respectively, the mean diffusing capacity for carbon monoxide was 74.8 ± 20.6%, the median 6-minute walk distance was 347 (220) meters and the median value of N Terminal-pro brain natriuretic peptide was 506.0 (1450.0) pg/mL. In total, 60.2% of the patients were under pulmonary arterial hypertension-targeted therapy at the time of enrolment; specifically, riociguat was received by 35.7% of the patients and combination therapy was the preferred strategy for 16% of the patients. In total, 74 patients were evaluated for pulmonary endarterectomy (PEA), 34 (45.9%) were assessed as operable but only 23 of those (31.1%) finally underwent PEA. The remaining 40 patients were ineligible for PEA according to the operability assessment and 13 (17.6%) of them underwent balloon pulmonary angioplasty. The age of the non-operable patients was significantly higher than the operable patients (p < 0.001), while there was no significant difference with regard to the history of coagulopathies between the operable and non-operable patients (p = 0.33).

AbstractSince the earliest works on the understanding of different forms of pulmonary hypertension, thrombosis has been involved in the pathophysiology of the disease, both in pulmonary arterial hypertension (PAH) and in chronic thromboembolic pulmonary hypertension (CTEPH). Autopsy and then pathophysiological data paved the way for the use of anticoagulants as a treatment for PAH and CTEPH. In PAH their role has diminished with the advent of specific targeted therapies, but they are still prescribed in more than half of PAH patients, because of concomitant venous thromboembolism or atrial fibrillation. In CTEPH long-term anticoagulant therapy is the cornerstone of the management. The recent development of direct oral anticoagulants (DOACs) raises the question of the best anticoagulation strategy, both in patients with PAH and in patients with CTEPH. In this review, we present an overview of the history of anticoagulants in the management of patients suffering from PAH or CTEPH, an update of the available data on the underlying rationale of their use in these subjects, an alert on the potential risks of using DOACs in these poorly explored situations, and the setting up of dedicated trials to evaluate the best anticoagulant treatment strategies in patients suffering from PAH or CTEPH.

SummaryChronic thromboembolic pulmonary hypertension (CTEPH) is the result of single or recurrent pulmonary thromboemboli that are thought to develop into organized pulmonary arterial obstructions by recurrent embolism and in situ thrombosis. Radioisotopic ventilation-perfusion scanning (V/Q scan) is a safe and highly sensitive test for pulmonary thromboembolic disease. The aim was to assess the natural history of thrombus expansion. We performed a prospective quantitative evaluation of ventilation/perfusion scintigrams (V/Q scans) in 20 patients with severe unoperated CTEPH. The baseline V/Q scan of each patient served as a reference for the second scan 21.7 ± 8.2 months later. Planar images with intravenous 99mTc-labeled human albumin macroaggregates were reconstructed in six standard projections. Perfusion scans were analyzed by a semiquantitative evaluation. In parallel, hemodynamics and clinical condition were prospectively observed. Lung perfusion scintigrams analyzed by a semi-quantitative method in patients with severe unoperated CTEPH show an apparent decrease of segmental flow abnormalities over time, paralleling right ventricular decline.

The COVID-19 pandemic has affected the physical and mental health of people around the world. This may be particularly true for patients with life-threatening diseases. We analyzed the level of fear of COVID-19 (FCV-19S), the prevalence of anxiety (HADS-A) and depression (HADS-D) in pulmonary arterial and chronic thromboembolic pulmonary hypertension (PAH and CTEPH) patients during the COVID-19 pandemic. In this multicenter prospective study, 223 patients (63% females, 66% PAH) with age range 18–90 years were included. The fear of COVID-19 was high, at a mean level of 18.9 ± 7.4 points. Anxiety (HADS-A ≥ 8 points) was diagnosed in 32% of all patients, depression (HADS-D ≥ 8 points) in 21%, and anxiety or depression in 38%. FCV-19S was higher in woman and in elderly people (p = 0.02; p = 0.02, respectively). In the multivariate analysis, FCV-19S higher than the median increased the odds ratio of anxiety, but not of depression (R 6.4 (95%CI 2.0–20.0), p = 0.002; OR 1.9 (0.9–3.9), p = 0.06, respectively). History of COVID-19 increased risk of both HADS-A and HADS-D. Patients with PAH and CTEPH, especially woman over 65 years and those who had been infected with COVID-19, may need additional psychological support due to fear of COVID-19, anxiety or depression.
