What is Hypertrophic Cardiomyopathy?
Hypertrophic cardiomyopathy is a heart muscle disease characterised by abnormal thickening of the ventricular walls. In some patients, the thickened muscle obstructs blood flow; 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 Malaysia
- Advances in hypertrophic cardiomyopathy (HCM) care include cardiac MRI to assess heart muscle thickening and scarring, advanced echocardiography to evaluate blood-flow obstruction, and genetic testing to support diagnosis and family screening. For adults with ongoing symptoms, cardiac myosin inhibitors provide a targeted treatment when standard medicines aren't effective. Patients with continual symptoms may be considered for procedures to reduce septal thickness, like surgical myectomy or alcohol septal ablation, at specialized centers. Implantable cardioverter-defibrillators (ICDs) might be recommended for those at higher risk of sudden cardiac death. Availability of specific treatments and procedures can vary by hospital in Malaysia, so it's important to confirm with the treating facility.
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) : some HCM patients have an increased risk of sudden cardiac death, and ICD decisions are based on individual risk assessment.

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.
MediRehab (a chain of Rehab centres, part of MediGence) provides comprehensive tele-rehabilitation services designed to support hypertrophic cardiomyopathy patients in Malaysia. These services include:
- Individualised Exercise: Specialists can recommend appropriate physical activity based on symptoms, disease severity, and individual needs.
- 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.
- Long-Term Follow-Up: Regular cardiology assessments help monitor symptoms, heart function, rhythm, and response to treatment.
- Select medicines based on symptoms, obstruction, heart rhythm, and overall heart function. 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.
