Study description

Hypertrophic cardiomyopathy (HCM) is an inherited heart disease characterised by an increased wall thickness or mass of the left ventricular wall, with a broad clinical spectrum. HCM is classified into two types based on the presence or absence of left ventricular outflow tract (LVOT) obstruction, a distinction that influences patient management. The obstructive form of HCM (oHCM) is observed in approximately 66% of patients.
The prevalence of HCM was initially estimated at 1 in 500 individuals (0.2%) in a U.S. study. Further U.S. and European studies suggest a lower prevalence of clinically diagnosed HCM. In addition, it has been suggested that some individuals may live normal lifespans undiagnosed because the absent of significant symptoms or major interventions.
Estimating the prevalence of HCM is problematic due to several factors, including the relative rarity of the condition, the high proportion of asymptomatic patients, and diagnostic challenges. Large-scale epidemiological studies on the demographics and morbidity burden of HCM in Europe are scarce.
This study aims to estimate the prevalence of HCM and oHCM across several European countries and different healthcare settings.
