The impact of residual pulmonary obstruction on the outcome of patients with pulmonary embolism is uncertain.We recruited 647 consecutive symptomatic patients with a first episode of pulmonary embolism, with or without concomitant deep venous thrombosis. They received conventional anticoagulation, were assessed for residual pulmonary obstruction through perfusion lung scanning after 6 months and then were followed up for up to 3 years. Recurrent venous thromboembolism and chronic thromboembolic pulmonary hypertension were assessed according to widely accepted criteria.Residual pulmonary obstruction was detected in 324 patients (50.1%, 95% CI 46.2–54.0%). Patients with residual pulmonary obstruction were more likely to be older and to have an unprovoked episode. After a 3-year follow-up, recurrent venous thromboembolism and/or chronic thromboembolic pulmonary hypertension developed in 34 out of the 324 patients (10.5%) with residual pulmonary obstruction and in 15 out of the 323 patients (4.6%) without residual pulmonary obstruction, leading to an adjusted hazard ratio of 2.26 (95% CI 1.23–4.16).Residual pulmonary obstruction, as detected with perfusion lung scanning at 6 months after a first episode of pulmonary embolism, is an independent predictor of recurrent venous thromboembolism and/or chronic thromboembolic pulmonary hypertension.

Chronic thromboembolic pulmonary hypertension (CTEPH) is a complication of unresolved organised pulmonary emboli/thrombi obstructing the major pulmonary arteries. The aim of this study was to estimate the incidence and risk factors of CTEPH in a cohort with first venous thromboembolism (VTE). This was a population-based cohort study of patients with first VTE and no active cancer in England between 2001 and 2012. CTEPH was assessed using a rigorous case-ascertainment algorithm. Risk factors for CTEPH were studied using a nested case-control approach by matching CTEPH cases to VTE patients without CTEPH. Adjusted odds ratios (OR) of comorbidities were estimated from conditional logistic regression. During 81,413 person-years of follow-up among 23,329 patients with first VTE (mean follow-up 3.5 years; maximum 11.0 years) 283 patients were diagnosed with CTEPH (incidence rate 3.5 per 1000 person-years); cumulative incidence was 1.3% and 3.3% at 2 and 10 years after pulmonary embolism, and 0.3% and 1.3% following deep vein thrombosis (DVT), respectively. Risk factors for CTEPH included age over 70, OR 2.04 (95% CI 1.23 to 3.38), female gender, 1.44 (1.06 to 1.94), pulmonary embolism at first VTE, 3.11 (2.23 to 4.35), subsequent pulmonary embolism and DVT, 3.17 (2.02 to 4.96) and 2.46 (1.34 to 4.51) respectively, chronic obstructive pulmonary disease 3.17 (2.13 to 4.73), heart failure 2.52 (1.76 to 3.63) and atrial fibrillation, 2.42 (1.71 to 3.42). CTEPH develops most commonly after pulmonary embolism and less frequently after DVT. Awareness of risk factors may increase referrals to specialised centres for confirmation of CTEPH and initiation of specific treatment.

Abstract Background Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare form of pulmonary hypertension caused by blood clots and scar tissue in the blood vessels of the lungs. Health-related quality of life is often significantly impaired in patients with CTEPH. However, a better understanding of how CTEPH symptoms affect patients’ lives is needed to optimally assess the impact of the disease and treatment. Objectives This qualitative study aimed to better understand the symptoms of CTEPH and how they affect patients’ lives, as well as to determine the appropriateness of the Pulmonary Arterial Hypertension – Symptoms and Impact (PAH-SYMPACT™) questionnaire for use in this patient population. Methods Adults diagnosed with CTEPH, recruited from two clinical sites in the US, participated in one-to-one qualitative telephone interviews. They described their experience of CTEPH symptoms and the impact these symptoms have on their lives. They also provided feedback on the comprehensibility and relevance of the PAH-SYMPACT™‘s instructions, items, and response options. Results Participants (N = 12) had a mean age of 62.5 years. Two thirds were female and most (83%) had undergone pulmonary endarterectomy and/or balloon pulmonary angioplasty. The most frequently endorsed symptoms were shortness of breath (endorsed by all 12 participants), fatigue (11 participants), and lightheadedness (10 participants). All participants identified shortness of breath as an “extremely important” symptom, and seven participants rated fatigue as “extremely important.” The most frequent impacts of CTEPH were on ability to walk quickly (endorsed by all 12 participants), ability to walk up inclines or stairs (11 participants), and ability to carry things (11 participants). The PAH-SYMPACT™ items were relevant to most participants and reflected their experience of CTEPH. All participants indicated that no important CTEPH symptoms were missing from the PAH-SYMPACT™. Overall, the instructions, items, and response options of the PAH-SYMPACT™ were clear and easy to understand. Conclusions The symptoms and impacts experienced by patients with CTEPH align with items included in the PAH-SYMPACT™. The PAH-SYMPACT™ appears to be fit for purpose for assessing disease status in patients with CTEPH.

Riociguat is included in international guidelines and local clinical protocols for the treatment of pulmonary hypertension (PH) and chronic thromboembolic pulmonary hypertension (CTEPH), where it is the first choice drug for the treatment of patients with inoperable, persistent and recurrent forms of CTEPH. Therefore, it is necessary to include this drug in the GVoFMC (The Guaranteed Volume of Free Medical Care) reimbursement lists and the CSHI (Compulsory Social Health Insurance) system, which will alleviate access to medication for patients suffering from PH and CTEPH. Purpose of the study. Determination of the cost effectiveness parameters of using riociguat in comparison with bosentan and combined therapy of bosentan/sildenafil in medication therapy of CTEPH. Material and methods. A Markov model of CTEPH dynamics in patients with riociguat prescription was developed in comparison with application of bosentan and sildenafil. Modeling step was 16 weeks, modeling horizon – 10 years. Direct medical costs per patient were taken into account in the model, including the cost of drug therapy, costs of outpatient visits due to CTEPH, hospitalization costs due to clinical deterioration of CTEPH, emergency calls. Results and discussion. The results of “cost-effectiveness” Markov pharmacoeconomic modeling showed that riociguat application reveals a dominant position in comparison with the practice of using bosentan with addition of sildenafil for specific therapy at deterioration of patient's condition up to III-IV functional class (FC). Riociguat is characterized by the best values of “cost effectiveness” coefficients according to efficiency criterion of FC increase and the “value of 6-min walk distance test”. The results of analysis of the impact on budget showed that inclusion of riociguat in GVoFMC/CSHI will lead to budget savings of 154 million tenge in the first year, 294 million tenge in the second year and 415 million tenge in the third year compared to the existing clinical practice without riociguat use. Conclusions. On the basis of conducted complex pharmacoeconomic analysis, the application of riociguat in patients with inoperable or persistent/ recurrent form of CTEPH is a more preferable strategy in comparison with the strategy of application of bosentan with addition of sildenafil and will allow to reduce budget expenses within the framework of GVoFMC and CSHI system. Keywords: pulmonary hypertension, chronic thromboembolic pulmonary hypertension, riociguat.
