Clinical and economic burden of obstructive hypertrophic cardiomyopathy in the United States.

In a real-world population, oHCM was associated with substantial increases in HRU and incremental costs of ∼$20,000/year when compared with matched controls-a difference that increased to ∼$35,000/year among symptomatic patients. Further studies are warranted to understand the potential impact of specific therapies on HRU and the economic burden of oHCM.
