Understanding it
About Hypertrophic cardiomyopathy deep dive, and what to do next.
In HCM the walls of the left ventricle thicken without an obvious cause such as high blood pressure. In some people the thickened septum obstructs blood leaving the heart, causing breathlessness and exertional symptoms; in others the main issue is stiffness of the muscle or a tendency to arrhythmia. Severity varies enormously, even within one family, and many people live a full life with minimal restriction.
Assessment centres on echocardiography, cardiac MRI, ambulatory ECG monitoring and exercise testing, with a gene panel used to guide family screening. Care is best delivered through an ICC clinic, where sudden-death risk is scored and treatment tailored, from medication to septal reduction in obstructive disease. Most people start with their GP, who can refer to a consultant cardiologist at an inherited cardiac conditions (ICC) clinic. In many parts of the UK, routine NHS referrals for this kind of problem currently take 20-45+ weeks, whereas an initial private consultation is typically available within around two weeks.
