What is Hypertrophic Cardiomyopathy?

Hypertrophic Cardiomyopathy is a heart muscle disease characterised by abnormal thickening of the ventricular walls that cannot be explained solely by conditions such as high blood pressure or abnormal heart valves. In some patients, the thickened muscle obstructs blood flow from the heart, while in others, the disease is non-obstructive. HCM can be inherited and may occur at different ages.

What is the Importance of Timely Treatment?

Timely treatment of Hypertrophic Cardiomyopathy helps control symptoms, assess whether thickened heart muscle is obstructing blood flow, reduce the risk of complications such as heart failure and arrhythmias, and identify patients who may benefit from an implantable cardioverter-defibrillator (ICD). Regular follow-up also supports long-term heart health by guiding medicines, activity, lifestyle, and family screening.

What are the Common Symptoms of Hypertrophic Cardiomyopathy?

  • Shortness of Breath: Breathlessness may occur during physical activity or, in more advanced cases, at rest.
  • Chest Pain: Some patients experience chest discomfort, particularly during exertion.
  • Palpitations: A sensation of a racing, pounding, or irregular heartbeat may occur because of abnormal heart rhythms.
  • Dizziness: Reduced cardiac output or abnormal rhythms may cause lightheadedness, particularly during activity.
  • Fainting: Episodes of unexplained fainting may occur and require medical evaluation, especially in people with known HCM.
  • Fatigue: A reduced ability of the heart to fill or pump efficiently can cause tiredness and reduced exercise tolerance.

Causes and Risk Factors of Hypertrophic Cardiomyopathy

Causes

  • Inherited Genetic Changes: Most familial HCM is linked to genetic variants that affect proteins involved in heart muscle contraction.
  • Spontaneous Genetic Changes: Some patients develop HCM without a known family history.
  • Unexplained Causes: In some individuals, no specific genetic or other cause is identified.
  • Associated Conditions: Some heart-muscle disorders can produce thickening that resembles HCM and require careful evaluation to distinguish them from true HCM.

Risk Factors

  • Family History: Having a first-degree relative with HCM or unexplained sudden cardiac death can increase risk.
  • Genetic Predisposition: Inherited disease-causing variants can increase susceptibility.
  • Age: HCM can become apparent during childhood, adolescence, adulthood, or later life.
  • Previous Abnormal Cardiac Findings: Unexplained heart-muscle thickening or abnormal ECG findings may prompt further assessment.
  • Family History of Sudden Cardiac Death: This may be an important factor in individual risk assessment.

Latest Research and Technologies in the Treatment of Hypertrophic Cardiomyopathy in the United Arab Emirates

  • For patients with persistent severe obstruction despite medical therapy, surgical septal myectomy and alcohol septal ablation remain established septal-reduction procedures, particularly when performed by experienced HCM teams. Current research is moving toward precision treatment, including advanced cardiac MRI with 4D flow assessment, myocardial energetics, and gene-targeted therapies that could eventually address the underlying genetic mechanisms of HCM.

Treatment options for Hypertrophic Cardiomyopathy

Septal Myectomy: This open-heart surgical procedure (Morrow procedure) remains the gold-standard intervention to physically excise a portion of the hypertrophied septum and relieve left ventricular outflow tract (LVOT) obstruction.

Alcohol Septal Ablation: A minimally invasive, catheter-based alternative to surgery where pure alcohol is injected into a septal branch artery to induce a localised controlled infarction, thinning the muscle to reduce obstruction.

Implantable Cardioverter-Defibrillator (ICD) : Because HCM is a leading cause of sudden cardiac death in young people and athletes due to ventricular arrhythmias, primary or secondary prevention with an ICD is an essential treatment pillar.

Heart Transplantation : For the small percentage of HCM patients who progress to end-stage, non-obstructive "burnt-out" heart failure, an orthotopic heart transplant is the final definitive option.

  • Clinical assessment:
    • Medical and Family History: Assessment of symptoms, exercise tolerance, previous fainting, family history of HCM, and sudden cardiac death.
    • Physical Examination: Evaluation for heart murmurs, abnormal heart sounds, blood pressure changes, and signs of heart failure.
    • Electrocardiogram (ECG): May identify abnormal electrical patterns associated with HCM.
    • Holter or Ambulatory ECG Monitoring: Detects intermittent arrhythmias that may not appear on a standard ECG.
    • Exercise Testing: May assess exercise capacity, blood pressure response, symptoms, and exercise-related obstruction.
    • Genetic Testing: May be offered to selected patients to identify disease-causing variants and support family screening.
  • Imaging Tests:
    • Echocardiography: The main imaging test used to assess heart-muscle thickness, heart function, valve movement, and obstruction.
    • Cardiac MRI: Provides detailed images of heart structure and can identify myocardial scar and other tissue characteristics.
    • Stress Echocardiography: May reveal obstruction or abnormalities that become apparent during exercise.
    • Chest X-ray: May help evaluate heart size and associated lung findings when clinically indicated.
    • Cardiac CT: Consider in selected patients when additional anatomical information is needed.

  • Cardiac Rehabilitation: Selected patients may benefit from structured, supervised rehabilitation.
  • Physical Conditioning: Gradual activity can help maintain functional capacity while avoiding inappropriate exertion.
  • Weight Management: Maintaining a healthy weight can reduce additional cardiovascular strain.
  • Beta-blockers and certain calcium-channel blockers may help reduce symptoms and improve ventricular filling. Selected patients with obstructive HCM may receive cardiac myosin inhibitors, while antiarrhythmic or anticoagulant medicines may be prescribed when clinically indicated. Treatment should be supervised by a cardiologist experienced in HCM.

Frequently Asked Questions

HCM is generally a long-term condition, not one that is permanently cured. Recovery after procedures such as septal myectomy or alcohol septal ablation varies, while symptom control with medicines may occur gradually. Regular follow-up is important.

Many people with HCM can walk and remain physically active. The appropriate level of activity depends on symptoms, obstruction, heart rhythm, and individual risk, so discuss exercise recommendations with an HCM specialist.

Many advanced UAE cardiac centres offer echocardiography, cardiac MRI, ambulatory ECG monitoring, genetic testing, electrophysiology services, ICD implantation, septal myectomy, and catheter-based procedures for appropriately selected patients.

Many major UAE hospitals have international patient departments that help overseas patients with medical records, appointments, treatment coordination, accommodation, interpretation (where available), and follow-up arrangements.

Consider a centre with experience in HCM, advanced cardiac imaging, electrophysiology, genetic evaluation, risk assessment, septal reduction procedures, ICD implantation, and long-term follow-up. A multidisciplinary HCM programme can be particularly valuable for complex cases.

The success rate for HCM treatment is 80-98%; outcomes depend on HCM type, symptoms, degree of obstruction, heart function, arrhythmia risk, age, and the treatment used. Appropriate treatment can significantly improve symptoms and reduce complication risk in selected patients.

Many UAE cardiac centres have cardiologists, electrophysiologists, cardiac surgeons, and imaging specialists experienced in diagnosing and managing HCM. Patients should consider the centre's specific expertise and experience with their type of disease.

Risks depend on the treatment. Medicines may cause side effects such as low blood pressure or slow heart rate, while septal myectomy, alcohol septal ablation, ICD implantation, and catheter procedures have specific procedural risks. The treating specialist should discuss the risks and benefits for each patient.

Hypertrophic cardiomyopathy is a heart-muscle condition, not an injury. If someone with HCM develops severe chest pain, fainting, severe breathlessness, or a sustained rapid heartbeat, urgent medical evaluation is required.

HCM does not usually cause physical or skeletal deformities. However, severe disease or complications such as heart failure or dangerous arrhythmias may affect physical capacity and quality of life.

Yes. Breathlessness, chest discomfort, fatigue, arrhythmias, activity restrictions, and concerns about inherited disease can affect daily life. Appropriate treatment, monitoring, rehabilitation, and psychological support may help patients maintain function and well-being.

Untreated or inadequately monitored HCM may lead to worsening symptoms, heart failure, atrial or ventricular arrhythmias, blood clots in some patients, and an increased risk of sudden cardiac death in a subset of patients. Regular specialist evaluation helps identify and manage these risks.

Inherited HCM cannot generally be prevented. However, people with a family history can undergo appropriate cardiac evaluation and, when indicated, genetic counselling and testing. Managing other cardiovascular risk factors and maintaining regular specialist follow-up can support overall heart health.

Yes. HCM can affect people of any age or sex but is more likely in individuals with a family history or a disease-causing genetic variant associated with HCM. Clinicians may also identify the condition during evaluation of unexplained heart-muscle thickening or abnormal ECG findings.
