Study Summary
In preparation for a future mechanistic study, investigators now propose to test the specific hypothesis that carnitine consumption is not reduced in PAH, that plasma carnitine levels are stable over time in PAH and that carnitine supplementation in PAH can increase plasma carnitine and thereby delivery of carnitine to the RV and possibly improve RV function. Investigators propose three aims in humans to test this mechanistic hypothesis, 1) Measure the oral consumption of carnitine in human PAH. This aim will use food diaries and carnitine supplement use questionnaires in PAH patients to test the hypothesis that carnitine supplementation is uncommon in PAH and food consumption is adequate. Aim 2) Measure the stability over time in plasma carnitine levels in PAH patients. This aim will test the hypothesis that plasma carnitine is not affected by disease severity and is stable over time in PAH patients. Investigators will measure plasma carnitine concentration and markers of fatty acid oxidation at Visit 1 and Visit 2. 3) Perform a mechanistic pilot study using carnitine supplementation to enhance circulating carnitine in PAH. This small pilot study will test the hypothesis that carnitine supplementation increases plasma carnitine (primary endpoint) and will test for physiologic effects using six minute walk testing, echocardiography and plasma markers of lipid metabolism.
