Summary

Pulmonary arterial hypertension (PAH) is a rare blood vessel disorder of the lung in which the pressure in the pulmonary artery (PA) rises above normal levels and may become life threatening. PAH is frequently misdiagnosed and has often progressed to late stage by the time it is accurately diagnosed. PAH has been historically chronic and incurable with a poor survival rate. However, new treatments are available which have significantly improved prognosis. Right-heart catheterization (RHC) is the most accurate and useful test for PAH, and the only test that directly measures the pressure inside the PA. It is performed in all patients at least once, to get a definitive diagnosis of PAH.

The most commonly used medication for this purpose is intravenous nitroprusside, however this medication in about 25-30% of patients is not well tolerated as it cause fast heart rates, which is not well tolerated by patients with pulmonary hypertension and/or heart failure. The CARVE study assesses the effect of Clevidipine, an ultra-short acting vasoselective calcium antagonist, on pulmonary vascular resistance (PVR) and its utility for pulmonary vasoreactivity testing during right heart catheterization (RHC) of patients with pulmonary hypertension (PAH).

Conditions

  • Hypertension, Pulmonary

Interventions

DRUG

Clevidipine

The clevidipine infusion is to be administered via IV infusion at a starting dose of 0.5 mg/hour. The dose may be doubled every three (3) minutes to a maximum dose of 32 mg/hr as tolerated, until a 20% reduction in PVR is achieved or until the patient experiences hypotension (SBP\< 80 mmHg), hypertension (SBP\>150 mmHg), tachycardia (120 beats per minute), bradycardia (\<50 beats per minute), or symptoms of hypotension or ischemia (chest pain, anxiety, nausea, vomiting), allergic reaction (hives, urticaria) or other adverse event. Clevidipine infusion may be terminated at any time for a safety reason or at the investigator's discretion.
