What is positive Vasoreactivity testing?
Positivity of acute vasoreactivity test (AVT) is “a fall of at least 10 mmHg in mean pulmonary artery pressure (PAP); a fall to an absolute mean PAP less than 40 mmHg; and unchanged or increased cardiac output”.
What drug class is riociguat?
Riociguat is in a class of medications called soluble guanylate cyclase (sGC) stimulators. It works by relaxing the blood vessels in the lungs to allow blood to flow easily.
Does Adempas lower blood pressure?

What is the difference between riociguat and Vericiguat?
Riociguat’s ongoing clinical development program includes PH-IIP and diffuse cutaneous sclerodermia, as well as an exploratory study in cystic fibrosis. Vericiguat is currently in late stage clinical development for the treatment of heart failure with reduced and also with preserved ejection fraction (HFrEF and HFpEF).
What does Vasoreactivity mean?
In (A), vasoreactivity is defined as a≥30% decrease in PVR with vasodilator compared to baseline. In (B), vasoreactivity is defined as a≥12% decrease in mPAP with vasodilator compared to baseline.
What does pulmonary hypertension look like on ECG?
In pulmonary hypertension, the electrocardiogram (ECG) may demonstrate signs of right ventricular hypertrophy, such as tall right precordial R waves, right axis deviation and right ventricular strain (Figure 1). The higher the pulmonary artery pressure, the more sensitive is the ECG.

How does riociguat cause anemia?
The mechanism of anemia is proposed to be due to its vasodilator effects which could result in bleeding from AVMs or telangiectasias.
What is Vasoreactivity testing in PAH?
Vasoreactivity testing is to be done with short acting selective pulmonary vasodilator agents (inhaled nitric oxide, iv epoprostenol, iv adenosine): A reduction of mean pulmonary artery pressure ≥ 10 mmHg to reach an absolute value of ≤ 40 mmHg with an increased or unchanged cardiac output is a positive test result …
