The Hidden Killer 85% of People Don’t Know They Have
Understanding the Hidden Threat: Hypertrophic Cardiomyopathy
When it comes to heart health, heart attacks often dominate the conversation. However, there is another condition that poses a significant risk, especially for younger individuals. This condition, known as hypertrophic cardiomyopathy (HCM), is a lifelong genetic disorder that can go undiagnosed and potentially lead to sudden death.
What is HCM?
Hypertrophic cardiomyopathy affects approximately 1 in 500 people. It causes the heart muscle to thicken, making it harder for the heart to pump blood effectively. This thickening can obstruct blood flow, leading to complications such as heart failure, irregular heartbeats, or even sudden cardiac arrest.
It is the most common inherited heart disease, with a 50% chance of a child developing it if one parent has HCM. Younger individuals are particularly at risk because symptoms may not appear until it’s too late.
Despite its prevalence, only around 100,000 cases have been diagnosed, meaning that roughly 85% of those affected may be unaware they have the condition. According to the Heart Failure Society of America, this lack of awareness is concerning.
The Mystery Behind HCM
Although HCM is inherited, the exact cause remains somewhat unclear. While genotyping plays a role in understanding the condition, it isn’t the complete picture. Dr. Theodore Abraham, an echocardiographer at UCSF Health, explains that for half of the patients with severe HCM, the causative gene hasn’t been identified. Moreover, the presence of a gene doesn’t always mean the disease will manifest.
The Challenge of Diagnosis
Early diagnosis is crucial for managing HCM, but traditional methods like standard heart ultrasounds may miss the condition. Dr. Abraham notes that patients with HCM often receive a clean bill of health after an echo, only to return years later in poor health. This highlights the need for more advanced diagnostic tools and regular monitoring.
Risk Factors and Symptoms
You could be at risk for HCM if you have family members with an implantable cardioverter-defibrillator (ICD) or pacemaker, or if someone in your family has had heart failure, stroke, or a heart attack. Even without a family history, certain symptoms may indicate the condition. These include:
- Lack of energy
- Shortness of breath
- Chest pain
- Fainting
- Swelling in the feet or ankles
While symptoms may not appear in younger individuals, they often develop later in life. Doctors can perform diagnostic tests to determine if HCM is present.
Managing HCM
Although there are no medications to treat HCM directly, lifestyle changes and regular medical check-ups can help manage the condition. Light to moderate physical activity and consistent visits to a cardiologist are essential for monitoring the disease’s progression.

Staying Informed About Heart Health
Heart health is a critical aspect of overall well-being, and it’s important to stay informed about potential risks. As research continues to evolve, new insights into conditions like HCM will help improve early detection and treatment strategies. By being proactive and aware of the signs, individuals can take steps to protect their heart health and potentially save lives.
