Abstract

This narrative review describes and appraises some relatively new studies investigating the efficacy and safety profile of soluble guanylate cyclase stimulator riociguat in patients suffering from pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH). It has been a while since the publication date of pivotal CHEST-1 trial in 2013. New studies available complement existing evidence, expound on specific questions and open new frontiers for CTEPH investigations going forward. In this paper authors attempted to present data from post-hocanalysis of the CHEST-1 study and real-world data on riociguat treatment, confirming the positive effect of the drug on hemodynamic parameters of the pulmonary circulation and the functional status of patients. This effect was shown previously in large randomized trials. The extremely important positive effect of riociguat demonstrated both in the group of inoperable patients with CTEPH and in patients with residual pulmonary hypertension after pulmonary thrombendarterectomy. Of great interest are the presented some authors results of reverse remodelling of the right heart chambers during riociguat therapy in CTEPH patients, including using unique imaging methods (magnetic resonance imaging and positron emission tomography) to evaluate targeted medicinal therapy in terms of right heart remodelling. The safety profile of the drug was analyzed in the long-term post-registration international, multicenter, prospective, observational study EXPERT (NCT02092818), which confirmed the good tolerability and safety of riociguat therapy in PAH and CTEPH patients.
