Hypertrophic Cardiomyopathy (HCM): Causes, Symptoms, and Treatment

Hypertrophic cardiomyopathy (HCM) is a genetic heart condition where the heart muscle becomes abnormally thick. This thickening can make it harder for the heart to pump blood, leading to potential complications such as arrhythmias or sudden cardiac arrest. Understanding and managing HCM is vital for maintaining heart health.

What Causes Hypertrophic Cardiomyopathy?

– Genetics: HCM is primarily inherited, caused by mutations in genes that control heart muscle proteins.
– Unknown Triggers: In some cases, the condition can arise without a family history, though the cause remains unclear.

Common Symptoms of Hypertrophic Cardiomyopathy

While some individuals with HCM experience no symptoms, others may notice:
– Shortness of breath, especially during physical activity.
– Chest pain or discomfort.
– Fainting (syncope), often triggered by exercise or stress.
– Fatigue and reduced ability to exercise.
– Palpitations or an irregular heartbeat.

Did You Know? Hypertrophic cardiomyopathy affects approximately 1 in 500 people, yet many cases go undiagnosed due to mild or absent symptoms.

How Is Hypertrophic Cardiomyopathy Diagnosed?

Diagnosis involves a combination of imaging and genetic tests:
– Echocardiogram: Provides detailed images of the heart to assess wall thickness and blood flow.
– Electrocardiogram (ECG): Detects irregular heart rhythms.
– Cardiac MRI: Offers a more detailed view of the heart structure.
– Genetic Testing: Helps identify mutations and assess family risk.

Treatment Options for Hypertrophic Cardiomyopathy

– Medications:
– Beta-blockers and calcium channel blockers to improve blood flow and reduce symptoms.
– Anti-arrhythmic drugs to control irregular heart rhythms.
– Surgical Procedures:
– Septal myectomy to remove excess heart muscle.
– Alcohol septal ablation to reduce thickened tissue.
– Implantable Devices:
– Implantable cardioverter-defibrillators (ICDs) to prevent sudden cardiac arrest.

Lifestyle Management Tips

– Avoid high-intensity sports or strenuous activities.
– Stay hydrated and avoid dehydration, which can worsen symptoms.
– Regular follow-ups with a cardiologist to monitor heart health.
– Inform family members about the condition and consider genetic screening.

Tom, a 40-year-old athlete, was diagnosed with HCM after experiencing fainting episodes during training. With lifestyle adjustments and an ICD implant, he now advocates for heart screenings in athletes to detect conditions like HCM early.
