Abstract

Riociguat is a soluble guanylate cyclase stimulator approved for the treatment of pulmonary arterial hypertension and chronic thromboembolic pulmonary hypertension. We studied the clinical and hemodynamics effects of transitioning 12 pulmonary hypertension patients from Phosphodiesterase type 5 inhibitor (PDE5i) to riociguat, and demonstrated a significant increase in cardiac index, fall in pulmonary vascular resistance, and improvement in functional class with this switch. Switch from PDE5i to riociguat appeared to be safe and fairly well tolerated in most patients.

摘要

利奥西呱是一种可溶性鸟苷酸环化酶刺激剂,已被批准用于治疗肺动脉高压和慢性血栓栓塞性肺动脉高压。我们研究了12例肺动脉高压患者从5型磷酸二酯酶抑制剂(PDE5i)转换为利奥西呱的临床和血流动力学效应,结果表明,转换后心脏指数显著增加,肺血管阻力下降,功能分级得到改善。在大多数患者中,从PDE5i转换为利奥西呱似乎是安全的,且耐受性良好。
