Currently, treatment of pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH) is focused on three signaling pathways: the NO pathway, the endothelin pathway, and the prostacyclin pathway. Riociguat is the only representative of stimulators of the soluble guanylate cyclase (sGC) class that is approved for the treatment of PAH and inoperable and persistent/recurrent CTEPH. The review presents data from clinical trials showing a positive effect of riociguat on the functional and hemodynamic profile of patients with PAH and CTEPH. In recent years there has been much discussion about the possibility of optimizing therapy by switching to drugs that affect a single pathogenesis target. Thus, sGC stimulants have obvious advantages over phosphodiesterase type 5 (PDE-5) inhibitors, including the ability of riociguat to exert pharmacological effects (due to a NO-independent mechanism of action) even in conditions of reduced NO production. Switching from PDE-5 to riociguat may be safe and appropriate, according to clinical trials presented in the review. In accordance with the guidelines for the diagnosis and treatment of pulmonary hypertension of the Eurasian Association of cardiologists from 2019, this strategy is approved when PDE5 therapy is ineffective in patients with PAH FC III (WHO).

The medical management of pulmonary arterial hypertension (PAH) has advanced considerably over the years. Once the diagnosis of PAH is made, the medical management includes both conventional and PAH-pathway specific therapies. Five different classes of drugs are now available targeting the endothelin, prostacyclin, and nitric oxide pathways (i.e. endothelin receptor antagonists, phosphodiesterase-5 inhibitors, soluble guanylate cyclase stimulators, prostacyclin analogues, and prostacyclin receptor agonists). These targeted therapies are approved for treatment of patients with PAH and chronic thromboembolic pulmonary hypertension (CTEPH) only. Long-term and event-driven studies of novel drugs have led to further improvement in the medical management of PAH and CTEPH. In this review, we will focus on the medical management of patients with PAH and CTEPH.

Pulmonary hypertension (PH), which includes pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH), is a progressive condition with significant morbidity and mortality due to right heart failure if left untreated. Riociguat is a soluble guanylate cyclase (sGC) stimulator and is the only treatment approved for both PAH and CTEPH. The objectives of this review are to describe the epidemiology and pathophysiology of PAH and CTEPH; synthesize the pharmacology, efficacy, safety, and utilization of riociguat; and discuss the role of the pharmacist in managing patients with these conditions. Data presented in this review is supported by peer reviewed literature, using PubMed and key words including pulmonary hypertension, pulmonary arterial hypertension, chronic thromboembolic pulmonary hypertension, and riociguat. The review draws on key studies and review articles that discuss the pathophysiology of PAH and CTEPH, as well as articles discussing the safety and efficacy of riociguat. The overall goal in the treatment of PAH and CTEPH is to improve long-term survival. Treatment planning depends on the type of PH, treatment goals, comorbidities, and risk profiles. Pharmacists serve a valuable role as part of the multidisciplinary team in the care of patients with PH, many of whom may have comorbidities that contribute to high costs and resource utilization. Riociguat is a first-in-class medication and the only approved treatment for both PAH and CTEPH. In clinical trials, riociguat has demonstrated favorable efficacy and tolerability. Riociguat is a valuable addition to the armamentarium of options for treating patients with PH.

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.

Arrhythmias are increasingly recognized as serious, end-stage complications of pre-capillary pulmonary hypertension, including pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH). Although arrhythmias contribute to symptoms, morbidity, in-hospital mortality, and possibly sudden death in PAH/CTEPH, there remains a paucity of epidemiologic, pathophysiologic, and outcome data to guide management of these patients. This review summarizes the most current evidence on the topic: from the molecular mechanisms driving arrhythmia in the hypertrophied or failing right heart, to the clinical aspects of epidemiology, diagnosis, and management.
