Effect of Metoprolol in Post Alcohol Septal Ablation Patients With Hypertrophic Cardiomyopathy

Summary

In this trial, the investigators will assess the effect of metoprolol in patients with hypertrophic cardiomyopathy who underwent alcohol septal ablation. The investigators will evaluate the quality of life, exercise tolerance, echocardiographic parameters and laboratory marker of heart failure and myocardial injury.
