Hypertrophic Cardiomyopathy Treatment in Malaysia

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.
