Drink More, and Eat Less: Advice in Obstructive Hypertrophic Cardiomyopathy

This report describes a series of symptomatic patients with obstructive hypertrophic cardiomyopathy with significant postprandial hemodynamic changes. This finding was identified by history, clinical examination, and echocardiography in 6 consecutive symptomatic patients referred for the evaluation of ventricular septal reduction therapy. Counseling these patients with dietary changes to include small frequent meals and to increase noncaffeinated fluid intake resulted in reductions in symptoms. In conclusion, severe symptoms in obstructive hypertrophic cardiomyopathy unresponsive to pharmacologic treatment frequently result in referral for definitive septal reduction therapy through surgery or, less frequently, alcohol septal ablation therapy. However, recognition of postprandial exacerbation in symptomatic patients may allow for nonpharmacologic dietary interventions that may obviate the need for more invasive therapies and their associated complications.
