RESUMO
Riociguat is licensed for the therapy of inoperable chronic thromboembolic pulmonary hypertension (CTEPH). We aimed to investigate whether age and comorbidities influence its tolerability and efficacy. Retrospectively, we analyzed data of tolerability, non-invasive, and invasive efficacy at baseline and follow up (FU) of all patients with CTEPH treated with riociguat at the Department of Internal Medicine V, University of Munich (n = 47), grouping patients according to age (<65 versus 65-79 versus ≥80 years) and risk factors for heart failure with preserved ejection fraction (HFpEF) (<2 versus ≥2 risk factors). During dose titration patients >80 years reported side effects more frequently (40%) than the other age groups (23% and 21% for patients <65 years and patients 65-79, respectively). Cessation of riociguat was rare and occurred independent of age. When looking at the total cohort of 47 patients, three patients stopped therapy and three patients had a reduced maintenance dosage, while 41/47 (87%) and all octogenarians reached the highest maintenance dosage of 7.5 mg/d. The frequency of any side effect was similar in patients in both risk factor groups, and hypotension was only observed in those with <2 risk factors. Parameters of efficacy improved significantly under riociguat treatment. Improvement in 6-min walk distance (6 mwd), N-terminal pro brain natriuretic peptide (Nt-proBNP) and hemodynamics did not differ between age or risk factor groups. In this small real-life cohort, riociguat was well-tolerated and effective in advanced age and risk factors for HFpEF.
RESUMO
Pulmonary hypertension is frequently underdiagnosed, and referral is delayed with subsequent impact on outcomes. During the SARS-CoV-2 pandemic, restrictions on daily life and changes in hospitals' daily routine care were introduced in Germany. This multi-centre study provides evidence for a negative influence of these restrictions on patient care in pulmonary hypertension expert referral centres.
RESUMO
Selexipag is an orally available selective IP prostacyclin-receptor agonist licensed since 2016 for the therapy of pulmonary arterial hypertension (PAH). We aimed to describe real-life data of patients with pulmonary hypertension (PH) treated with selexipag. We analyzed all patients initiated with selexipag from July 2016 to April 2018 at the Department of Internal Medicine V, University of Munich. Non-invasive and invasive parameters corresponding to the risk assessment were collected at baseline and follow-up (FU). Furthermore, we recorded tolerability. Twenty-six patients were treated with selexipag, of whom 23 had PAH and three had chronic thromboembolic PH. At baseline, most patients were in function class (FC) II or III (42% and 54%, respectively). All patients were under medical treatment for PH, mostly dual therapy (92%). One or more side effects were noted in 19 patients, while seven reported no side-effects. FU assessment was available in 20 patients after 149 ± 80 days of treatment. Nt-proBNP (median, baseline 1641 pg/mL, FU 1185 pg/mL, P = 0.05) and PVR (mean ± SD, baseline 8.5 ± 4.3 WU, FU 5.6 ± 1.1 WU; P < 0.05) improved significantly. At FU, at least one risk assessment parameter improved in nine patients (45%), all parameters remained in the same risk group in seven patients (35%), and at least one parameter deteriorated in four patients (20%). Interestingly, patients with any side effect throughout the dose titration had a better treatment response than those without any side effects. In our real-life cohort, the majority of patients with PH treated with selexipag showed a stable or improved risk assessment at FU.
