BACKGROUND: Among patients with pulmonary arterial hypertension (PAH), acute vasoreactivity testing during right heart catheterization may identify acute vasoresponders, for whom treatment with high-dose calcium channel blockers (CCBs) is recommended. However, long-term outcomes in the current era remain largely unknown. We sought to evaluate the implications of acute vasoreactivity response ...

Acute vasoreactivity testing (AVT), as a provocative test, can be performed during RHC for several reasons [2]. In patients with pulmonary arterial hypertension (PAH), the detection of pulmonary vasoreactivity may identify candidates for long-term response to calcium-channel blockers (CCBs), characterized by sustained clinical and hemodynamic improvement after 1 year of treatment, and it helps ...

Pulmonary arterial hypertension (PAH) has a progressive, unremitting clinical course. Vasoreactivity testing (VdT) during right heart catheterisation (RHC) identifies a subgroup with excellent long-term response to calcium channel blockade (CCB). Reporting on these patients is limited. Established in 2011, the Pulmonary Hypertension Society of Australia and New Zealand (PHSANZ) registry offers ...

As we can see from the illustration, Pulmonary Artery Vasoreactivity has many fascinating aspects to explore.

Pulmonary hypertension results in clinical deterioration and increases mortality risk in patients with lung disease (LD), including chronic obstructive pulmonary disease, interstitial lung disease and combined pulmonary fibrosis and emphysema. Though acute vasoreactivity testing predicts long term-survival of patients with pulmonary arterial hypertension (PAH), its clinical impact for patients ...

Question The purpose of vasoreactivity testing in pulmonary arterial hypertension (PAH) is to identify the small minority of patients who may benefit from an oral calcium channel blocker (CCB) and thus avoid the complicated parenteral medications.

A right heart catheterization (right heart cath) is considered to be the gold standard to definitively diagnose pulmonary hypertension.10 During a right heart cath, a venous access device is inserted in the patient and a specially designed balloon-tip catheter (e.g., Swan-Ganz catheter) is advanced into the central venous system.

Prognostic value of follow

Acute vasoreactivity test with inhaled nitric oxide (NO) is performed during diagnostic right heart catheterization (RHC) to identify patients with pulmonary arterial hypertension (PAH) who respond to calcium channel blockers. Our purpose was to investigate the prognostic importance of follow-up vasoreactivity test after treatment.

Purpose of Vasoreactivity Testing in Pulmonary Arterial Hypertension (PAH) The primary purpose of vasoreactivity testing in PAH is to identify patients who will respond favorably to long-term treatment with high-dose calcium channel blockers (CCBs), which can significantly improve survival in these select patients. 1
