Hypertrophic Cardiomyopathy
Conditions
Keywords
chest pain, dyspnea
Brief summary
The purpose of RHYME is to evaluate the safety and efficacy of ranolazine in Hypertrophic Cardiomypathy patients with chest pain or dyspnea despite treatment with standard medical therapy. This is a small, pilot, open-label (non-randomized) study of an approved drug for the treatment of angina in a novel patient population (adult patient population with hypertrophic cardiomyopathy).
