NCT02684786 · Status: WITHDRAWN · Phase: PHASE1 · Type: INTERVENTIONAL

Summary

Pulmonary hypertension Group 2 (PH 2) associated with left-sided heart disease is relatively common, is associated with a poor prognosis, and unfortunately there are no proven medical treatments beyond attempts at correcting the left sided heart disease. Many PH 2 patients have evidence of active constriction of blood vessels from increased nerve traffic. Use of agents or procedures which produce a reversible chemical blockage of this nerve traffic have not been systematically tested in PH 2. The investigators will test whether acute interruption of sympathetic nervous system tone, which local anesthetic block of the stellate ganglion in the neck, will improve PH2, and also test whether the high blood pressure drug reserpine, which blocks sympathetic nerve activity, will do so during a one month trial period.

Conditions

  • Pulmonary Artery Hypertension

Interventions

DRUG

reserpine

Patients with qualifying hemodynamics from prior right heart catheterization will receive open label reserpine, 0.05 mg by mouth daily for two weeks, then 0.10 mg by mouth daily for two weeks, and then have repeat non-invasive assessments of status

PROCEDURE

stellate ganglion block

Patients with suspected group 2 pulmonary hypertension by clinical and non-invasive assessments and are scheduled to undergo clinically indicated right heart catheterization will have pulmonary artery pressures measured. If qualifying severity of group 2 pulmonary hypertension is present, after clinically indicated assessment of inhaled nitric oxide, their baseline hemodynamics will be allowed to re-equilibrate over 10 minutes, and then ultrasound guided left stellate ganglion block with lidocaine will be performed, and hemodynamics reassessed 10 minutes afterward

DRUG

lidocaine

Patients with suspected group 2 pulmonary hypertension by clinical and non-invasive assessments and are scheduled to undergo clinically indicated right heart catheterization will have pulmonary artery pressures measured. If qualifying severity of group 2 pulmonary hypertension is present, after clinically indicated assessment of inhaled nitric oxide, their baseline hemodynamics will be allowed to re-equilibrate over 10 minutes, and then ultrasound guided left stellate ganglion block with lidocaine will be performed, and hemodynamics reassessed 10 minutes afterward
