Although hypertrophic cardiomyopathy (HCM) is the most common genetic cardiac disease,1,2 relatively few patients may be aware they have it1-3

The estimated
prevalence of HCM in adults is

1in500

or 0.2% of the general population1,3

  • In Canada, an estimated 76,000 people have HCM (0.2% of 38M)1-3
  • Recent studies that have focused on the molecular basis of HCM and genetic testing suggest a higher prevalence of HCM2,3
  • Despite this, at least 85% of Americans with HCM are likely undiagnosed1,3,4
