Abstract
Pulmonary arterial hypertension is a progressive disease that can lead to right-sided ventricular failure and premature death. Tailoring therapy to individual patient's needs, along with regular risk assessment, is integral for optimal outcomes in patients with pulmonary arterial hypertension. Results from the AMBITION trial support the use of upfront combination of tadalafil and ambrisentan. In a recent analysis of risk assessment in pulmonary arterial hypertension, abridged versions of the REVEAL 2.0 risk score were shown to be comparable to the full tools. In this report, we present a case series of the use of riociguat in upfront combination or sequentially, and the impact on risk scores as determined by the abridged REVEAL Lite 2.0 approach.
