The primary cause of HCM is the presence of mutations in genes that you were likely born with, and these genes are the "blueprint" for the heart muscle structure. In many cases, these mutations are passed down in families. These abnormalities lead to abnormal thickening or hypertrophy of the heart.

Hypertrophic cardiomyopathy (HCM) is the most common form of genetic heart disease and affects 1 in 500 people, yet many people go undiagnosed.

Many people with HCM have no or few symptoms which may account for why many people go undiagnosed. The most common signs and symptoms associated with HCM are shortness of breath, especially when exercising or being active, chest pain, dizziness, palpitations or feeling heart flutters. These symptoms can overlap with other heart conditions which can lead to a delay in the diagnosis of HCM.

There are two main subtypes of HCM: obstructive and non-obstructive. Obstructive HCM occurs when the abnormally thickened heart muscle blocks or obstructs blood from leaving the heart, leading to reduced blood flow. In contrast, non-obstructive HCM does not restrict blood flow despite the thickened heart muscle but can cause abnormal function of the heart.

Although there is no "cure" for HCM, most patients can expect to have a relatively normal life span. Treatment options depend on the type of HCM and the severity of the condition. Treatments can be tailored to each individual patient and include advanced therapies and medications.

In its progressive form, HCM can lead to serious complications, such as an increased risk of atrial fibrillation, stroke, heart failure and in rare cases, sudden cardiac death.
