Chronic thromboembolic pulmonary hypertension (CTEPH) is a common long-term complication of pulmonary embolism characterized by thromboembolic obstruction of the pulmonary arteries, vascular arteriopathy, vascular remodeling, and ultimately pulmonary hypertension (PH). Although pulmonary endarterectomy (PEA) surgery is the standard of care, approximately 40% of patients in the international CTEPH registry were deemed inoperable. In addition to lifelong anticoagulation, the cornerstone of PH-specific medical management is riociguat, a soluble guanylate cyclase stimulator. Medical management should be started early in CTEPH patients and may be used as a bridge to PEA surgery or balloon pulmonary angiography. Medical management is indicated for inoperable CTEPH patients and patients who have recurrence of PH after PEA surgery.

Chronic thromboembolic pulmonary hypertension (CTEPH) results from incomplete resolution of acute pulmonary emboli, organised into fibrotic material that obstructs large pulmonary arteries, and distal small-vessel arteriopathy. Pulmonary endarterectomy (PEA) is the treatment of choice for eligible patients with CTEPH; in expert centres, PEA has low in-hospital mortality rates and excellent long-term survival. Supportive medical therapy consists of lifelong anticoagulation plus diuretics and oxygen, as needed.An important recent advance in medical therapy for CTEPH is the arrival of medical therapies for patients with inoperable disease or persistent/recurrent pulmonary hypertension after PEA. The soluble guanylate cyclase stimulator riociguat is licensed for the treatment of CTEPH in patients with inoperable disease or with recurrent/persistent pulmonary hypertension after PEA. Clinical trials of this agent have shown improvements in patients' haemodynamics and exercise capacity. Phosphodiesterase-5 inhibitors, endothelin receptor antagonists and prostanoids have been used in the treatment of CTEPH, but evidence of benefit is limited. Challenges in the future development of medical therapy for CTEPH include better understanding of the underlying pathology, end-points to monitor the condition's progress, and the optimisation of pulmonary arterial hypertension therapies in relation to diverse patient characteristics and emerging options such as balloon pulmonary angioplasty.

Pulmonary Microcirculation

Chronic thromboembolic pulmonary hypertension (CTEPH) is a precapillary type of pulmonary hypertension with chronic obstruction of large and medium branches of pulmonary arteries along with secondary alterations in pulmonary microcirculation, which cause progressive increases in pulmonary vascular resistance and pulmonary arterial pressure and ensuing severe right heart dysfunction and heart failure. Pulmonary thromboendarterectomy (PTE) is the treatment of choice for CTEPH; however, this procedure is available not for all patients. Although the surgery performed in the conditions of centers with advanced experience generally shows good results, up to 40% of patients are technically inoperable or PTE is associated with a high risk of complications. At present, riociguat, the only officially approved drug from the class of soluble guanylate cyclase stimulators, is considered as a first-line treatment for inoperable and residual forms of STEPH. Introduction of riociguat to clinical practice can be called a real breakthrough in the treatment of patients with STEPH who cannot undergo PTE or those with relapse or persistent STEPH after the surgery.

Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare but life-threatening disease resulting from unresolved thromboembolic obstructions. Pulmonary endarterectomy (PEA) surgery is the gold-standard treatment as it is potentially curative; however, not all patients are deemed operable and up to one-third have persistent or recurrent CTEPH after the procedure. Pulmonary arterial hypertension (PAH) and CTEPH have similar clinical presentations and histopathological features, so agents shown to be effective in PAH have often been prescribed to patients with CTEPH in the absence of proven therapies. However, clinical evidence for this strategy is not compelling. A number of small uncontrolled trials have investigated endothelin receptor antagonists, prostacyclin analogues and phosphodiesterase type 5 inhibitors in CTEPH with mixed results, and a phase III study of the endothelin receptor antagonist bosentan met only one of its two co-primary end-points. Recently, however, the soluble guanylate cyclase stimulator, riociguat, was approved in the USA and Europe for the treatment of inoperable or persistent/recurrent CTEPH following positive results from the phase III CHEST study (Chronic Thromboembolic Pulmonary Hypertension Soluble Guanylate Cyclase–Stimulator Trial). This article reviews the current evidence for the use of pharmacological therapies in CTEPH.

Thromboembolic Pulmonary Hypertension

Introduction. Chronic thromboembolic pulmonary hypertension is a precapillary form of pulmonary hypertension that develops due to thrombotic mass obstruction of the pulmonary arteries. Balloon pulmonary angioplasty (BPA) is a new, alternative treatment method for inoperable chronic thromboembolic pulmonary hypertension (CTEPH), which demonstrated good hemodynamic and clinical effects. In this article we studied the long-term outcomes results after BPA. Material and methods. The study included 22 patients with inoperable CTEPH who were treated by BPA 6 (5; 8) interventions per patient. The results of the procedure were evaluated 2 months and 18 (12; 18) months after the last BPA. Results. A significant decrease in all important hemodynamic parameters was noted. There no difference between the date immediately after the operation and the long term period. However, the division of patients into groups with and without disease progression allow us to identify factors affecting the effectiveness of BPA (weight, the number of BPA procedures per patient, the total number of treated segmental arteries, the presence of coronary heart disease and chronic obstructive pulmonary disease, not the appointment of a concomitant pathogenetic pulmonary arterial hypertension (PAH) therapy. Conclusion. BPA is an effective method of treating patients with inoperable CTEPH, which demonstrates a good, sustainable long-term result. Patients with classical type 4 pulmonary hypertension receiving PAH-specific therapy are best responders to BPA.

Long Term Prognosis

Pulmonary hypertension as the result of chronic pulmonary thromboembolic disease is a serious condition with poor long-term prognosis. The condition is one of the more common cardiovascular diseases affecting Americans, yet it is severely underdiagnosed. Pulmonary thromboendarterectomy is the definitive treatment for chronic pulmonary hyper-tension as the result of thromboembolic disease; however. it is an uncommon procedure, primarily because of lack of recognition on the part of the clinicians. Patients affected by chronic thromboembolic pulmonary hypertension (CTEPH) may present with a variety of debilitating cardiopulmonary symptoms. However, once diagnosed, there is no curative role for medical management, and surgery remains the only option. Palliation therapy with medical management in order to delay surgery carries the risk of prolonging the disease and irreversibly damaging unaffected pulmonary vasculature.

Riociguat is a soluble guanylate cyclase stimulator approved for the treatment of inoperable and persistent/recurrent chronic thromboembolic pulmonary hypertension (CTEPH). In the 16-week CHEST-1 study, riociguat showed a favourable benefit–risk profile and improved several clinically relevant end-points in patients with CTEPH. The CHEST-2 open-label extension evaluated the long-term safety and efficacy of riociguat.Eligible patients from CHEST-1 received riociguat individually adjusted up to a maximum dose of 2.5 mg three times daily. The primary objective was the safety and tolerability of riociguat; exploratory efficacy end-points included 6-min walking distance (6MWD) and World Health Organization (WHO) functional class (FC).Overall, 237 patients entered CHEST-2 and 211 (89%) were ongoing at this interim analysis (March 2013). The safety profile of riociguat in CHEST-2 was similar to CHEST-1, with no new safety signals. Improvements in 6MWD and WHO FC observed in CHEST-1 persisted for up to 1 year in CHEST-2. In the observed population at 1 year, mean±sd6MWD had changed by +51±62 m (n=172)versusCHEST-1 baseline (n=237), and WHO FC had improved/stabilised/worsened in 47/50/3% of patients (n=176)versusCHEST-1 baseline (n=236).Long-term riociguat had a favourable benefit–risk profile and apparently showed sustained benefits in exercise and functional capacity for up to 1 year.

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.
