Hypertrophic Cardiomyopathy; A Common, Genetic Heart Condition That’s Significantly Underdiagnosed

Hypertrophic cardiomyopathy — or HCM — is a heart condition that’s more common than many people realize. It happens when the heart muscle becomes thicker than it should be. This can make it harder for the heart to pump blood and may lead to symptoms like chest pain, shortness of breath, dizziness or feeling unusually tired. But many people with HCM don’t notice any symptoms at all.

HCM is also genetic, meaning it runs in families. If a parent has HCM, their children have a higher chance of having it too. That’s why doctors often recommend that close family members get checked, even if they feel healthy. In many cases, screening a family member is how the condition is first discovered.

Even though HCM affects many people, it’s often underdiagnosed because its symptoms can look like asthma, anxiety or just being out of shape. Some people have no symptoms at all, and routine primary care visits don’t always catch it. Diagnosing HCM usually requires specific heart tests, like an echocardiogram, which are ordered only when a provider knows to look for the condition.

If you have symptoms or a family history of HCM or sudden cardiac events, talking with your doctor about screening is an important first step. Tests like an EKG or an echocardiogram can help identify HCM early and guide the right treatment plan.

HCM is common, genetic and often overlooked — but early detection can be life-changing.
