Insights
Ranolazine effectively treats angina in hypertrophic cardiomyopathy patients unresponsive to beta-blockers. This antianginal drug, by inhibiting late-sodium current, offers a new therapeutic option for refractory cases.
Area of Science:
- Cardiology
- Pharmacology
Background:
- Ranolazine is an antianginal medication that inhibits the late-sodium current (INaL).
- Its current clinical use is primarily for patients with coronary artery disease.
- Emerging evidence suggests potential benefits for angina in hypertrophic cardiomyopathy (HCM).
Observation:
- This report details two cases of HCM patients experiencing refractory angina despite beta-blocker therapy.
- Both patients were treated with ranolazine.
Findings:
- Ranolazine administration resulted in significant improvement in angina symptoms in both cases.
- The drug was effective even when standard beta-blocker treatments failed.
Implications:
- Ranolazine may be a viable therapeutic option for managing angina in HCM patients with refractory symptoms.
- Further research into ranolazine's efficacy and safety in HCM is warranted.
Abstract:
Ranolazine is an antianginal and works by inhibiting late-sodium current (INaL). However, its use is limited mostly to patients with coronary artery disease. However, literature has shown its potential benefit in relieving angina in hypertrophic cardiomyopathy. Hereby, we discuss two cases where ranolazine led to improvement in angina refractory to beta-blockers. In conclusion, ranolazine can be considered as a potential antianginal drug in patients with hypertrophic cardiomyopathy refractory to beta-blockers.
