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).

Primary Outcome Measures:
  • Safety of Ranolazine with regard to QT interval [ Time Frame: 60 Days ] [ Designated as safety issue: No ]
  • Safety of Ranolazine with regard to adverse events [ Time Frame: 60 Days ] [ Designated as safety issue: No ]
  • Safety of Ranolazine with regard to drug tolerability [ Time Frame: 60 days ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Improvement in number of episodes of angina per week [ Time Frame: Baseline and 60 Days post treatment ] [ Designated as safety issue: No ]
    Efficacy of ranolazine in HCM patients with respect to improvements in angina frequency (number of episodes of angina per week).

  • Improvement in dyspnea [ Time Frame: Baseline and 60 Days post treatment ] [ Designated as safety issue: No ]
    Efficacy of ranolazine in HCM patients with respect to improvements in dyspnea.

  • Improvement in quality of life [ Time Frame: Baseline and 60 Days post treatment ] [ Designated as safety issue: No ]
    Efficacy of ranolazine in HCM patients with respect to improvement in quality of life evaluation with the Seattle Angina Questionnaire (SAQ) and Kansas City Cardiomyopathy Questionnaire (KCCQ).
