About
The current trial is designed to assess the safety and efficacy of sustained oral administration of inorganic nitrate in patients with severe aortic stenosis and to assess the mechanisms by which inorganic nitrate enhances oxygen uptake and exercise capacity in this population.
Full description
This is a randomized double-blind crossover clinical trial, in which 22 subjects who underwent transcatheter aortic valve replacement (TAVR) for severe aortic stenosis (AS) three or more months prior to enrollment will receive the following 2 interventions, in randomized order: (1) Potassium nitrate (KNO3), at a dose of 12-18 mmol/d by mouth for 4 weeks, or; (2) Potassium chloride (KCl), at a dose of 12-18 mmol/d by mouth for 4 weeks. A 1-week washout period will be introduced between the 2 interventions. The purpose of the trial is to test the safety of KNO3 and its efficacy on a number of clinical and physiologic endpoints in subjects who underwent TAVR for severe AS.
