Hypertrophic Cardiomyopathy (HCM) is a condition, mostly inherited, in which the heart muscle becomes thickened.
People with this condition usually do not have symptoms. However, in some people with this condition, there is a risk of developing complications such as failure of the heart to pump blood and sudden death.
Currently it is difficult to say why some people develop these complications and others do not.
How Do We Study Hypertrophic Cardiomyopathy?
We use Magnetic Resonance Imaging (MRI) of the heart.
Below are videos of two beating hearts taken using an MRI scanner. The muscle in the heart with Hypertrophic Cardiomyopathy is thicker compared to the normal heart.
