What is Cardiac Myopathy?

Diseases or disorders of the heart muscle are called cardiomyopathy and result in poor heart function. In layman's terms, if this is not addressed, the heart stops pumping blood, leading to heart failure.

What is the Importance of Timely Treatment?


Preventing Heart Failure

Timely interventions relieve symptoms of cardiomyopathy, preventing heart failure. Treatment improves heart function and decreases the heart's workload with medication and lifestyle changes.

Reduction in Risk of Arrhythmias

Timely intervention can help control the sometimes deadly irregularity of heart rhythms (arrhythmias). Medications or devices, such as pacemakers or defibrillators, may be used to regulate heartbeats and prevent sudden cardiac arrest.

Improvement of Quality of Life

Diagnosis and treatment can effectively relieve breathlessness, increased tiredness, and swelling, thereby granting patients a better quality of life while allowing them to continue performing daily activities without significant restrictions.

Prevention of Complications

In case of a delayed intervention, complications arising out of cardiomyopathy could cause a stroke, thrombus formation, and even damage to the organs. Beginning early treatment minimises the long-term troubles that may arise from these factors.

Improved Outcomes in the Long Term
Patients receiving prompt interventions for cardiomyopathy tend to achieve long-term health benefits, with good heart function and longevity, mainly when these interventions target the underlying causes and symptoms.

Latest Research and Technologies in the Treatment of Cardiac Myopathy in Singapore


In Singapore, doctors are exploring innovative approaches to treating cardiomyopathy through advanced gene therapies, precision medicine, and AI-powered tools. A significant step includes initiating Asia's first multi-centre clinical trial, which will test a gene therapy for heart failure using the experimental drug SRD-001. This therapy, based on an adeno-associated virus (AAV), aims to improve the function of heart muscles in patients with heart failure and reduced ejection fraction (HFrEF). In cases of hypertrophic cardiomyopathy, the drug mavacamten has received approval in Singapore, giving patients a new treatment option. To expedite heart scan analysis, the SENSE AI system was implemented. This tool reduces the time required to identify problems related to coronary artery disease.

Cardiac Myopathy Prevention Tips


Control Your Blood Pressure
Control your blood pressure by maintaining a healthy diet, exercising regularly, and using medication as needed. This high blood pressure gradually affects the heart, leading to dilated cardiomyopathy.

Prevent Use of Excessive Alcoholic Beverages and Medications
Moderate drinking and abstaining from recreational drugs, especially cocaine, will prevent chronic intoxication from alcoholic cardiomyopathy that injures the heart muscle.

Maintain a Healthy Weight and Diet
Keep a balanced diet low in salt, sugar, and unhealthy fats. Proper nutrition and exercise will be managed to prevent weight gain or loss concerning obesity-associated heart diseases that lead to cardiomyopathy.

Regular Exercise
The heart is fed, and a healthy weight is maintained through regular physical activity. With a genetic predisposition to hypertrophic cardiomyopathy, persons should avoid vigorous and intense exercises as these can often trigger arrhythmias.

Observe and Manage Chronic Illnesses
Chronic diseases such as diabetes, high cholesterol levels, and thyroid disorders require monitoring and management to avoid putting the conditions to risk for possible development of cardiomyopathy and heart failure.

Treatment options for Cardiac Myopathy

The medical treatment for cardiac myopathy requires evaluating the patient's severity and medical condition to determine the appropriate course of action. The following are the treatment options:

Pacemaker and Defibrillators: In some cases, pacemakers or implantable cardioverter-defibrillators (ICDs) might be used to regulate the heart rhythm if arrhythmias are present.

Heart transplantation : It is defined as the surgical replacement of a diseased or damaged heart with a healthy one from a donor. This procedure is commonly reserved for patients with end-stage heart failure or severe heart conditions that are unresponsive to other treatments.

These are the standard diagnostic methods for diagnosing Cardiac Myopathy:

Clinical Assessment

  • Physical Exam: During this examination, the doctor will be keen to identify signs of heart failure or circulation diseases in the form of swellings at the legs, distended neck veins, and abnormal heart sounds (murmurs).
  • Medical History: The doctor will focus on family background, lifestyle habits (use of alcohol and drugs), history of previous medical conditions (hypertension, diabetes), and any symptoms like fatigue, shortness of breath, and chest pain.

Blood test

  • Blood tests: Certain markers, such as BNP (or B-type natriuretic peptide), are specific to heart failure, whereas troponin levels indicate damage to the heart muscle.
  • Genetic testing: Any mutation affecting such conditions as hypertrophic cardiomyopathy or arrhythmogenic right ventricular cardiomyopathy (ARVC) can be identified.

Imaging Studies

  • Echocardiogram (Ultrasound of the Heart): It assesses the heart's size, shape, and function, detecting structural defects or abnormalities in the heart valves. It also measures ejection fraction (blood pumped at each beat).
  • Electrocardiogram (ECG or EKG): ECG records the heart's electrical activity. It can detect abnormal heart rhythms (arrhythmias) that may be present in a case of cardiomyopathy.
  • Cardiac MRI (Magnetic Resonance Imaging): It assesses the degree of heart damage and identifies scar tissue in the heart, differentiating it into different types of cardiomyopathy (i.e., dilated, hypertrophic, and restrictive).
  • Chest X-ray: It can present signs of heart enlargement or fluid accumulation in the lungs, which are commonly observed symptoms of heart failure.
  • Stress Test: It evaluates blood flow and heart function under stress. Hence, if this person experiences symptoms upon exertion, such as chest pain or breathlessness, it can help identify possible causes.
  • Cardiac catheterisation (Angiogram): Cardiac catheterisation involves inserting a thin tube (catheter) into a blood vessel to measure direct pressure inside the heart and determine if there are blockages within the coronary arteries.

Biopsy

  • Endomyocardial Biopsy: In rare conditions, an endomyocardial biopsy (a small sample of heart tissue) is taken to diagnose specific types of cardiomyopathy, primarily because it may be more suggestive of restrictive cardiomyopathy or have an infectious or autoimmune origin.

MediRehab (a chain of Rehab centres, part of MediGence) provides comprehensive rehabilitation services to support patients through Teleconsulations and online therapy sessions.

Cardiac Rehabilitation (CR)

It refers to a supervised exercise program accompanied by dietary advice and stress management to improve cardiac function, limit the symptoms associated with cardiac disease, and educate patients on lifestyle changes to promote heart health.

Physical therapy

It enhances muscle strength and function and increases endurance in patients with cardiomyopathy. It includes heavy breathing exercises, as well as other functional training, to help achieve self-independence in daily activities.

Lifestyle Changes and Education

Medication adherence, heart-healthy diet, and abstinence from smoking/alcohol consumption are all within a patient's control. It is essential to educate patients about weight management in addition to risk reduction for overall long-term health.

Psychosocial Support

Counselling and support groups are invaluable support systems by which patients are assisted in coping with emotional stress and anxiety that stem from the effects of their disease.

Home-Based Rehabilitation
This offers exercise programs, virtual follow-ups, and wearable devices to ensure safety and track progress in rehabilitation for patients who cannot attend in-person programs.

The therapeutic agents for cardiac myopathy include ACE inhibitors, beta-blockers, and diuretics for symptom management and enhancement of heart function, as well as anticoagulants and antiarrhythmics for preventing blood clots and managing abnormal heart rhythms.

Frequently Asked Questions

There are many types, such as:

  • Dilated Cardiomyopathy: This occurs when the heart muscle stretches and becomes weakened.
  • Hypertrophic cardiomyopathy: Thickening of the heart muscle obstructs or resists blood from pumping out of the heart.
  • Restrictive Cardiomyopathy: This condition causes stiff heart walls that limit the heart's ability to expand and contract.
  • Arrhythmogenic right ventricular cardiomyopathy occurs when fatty or fibrous tissue replaces healthy heart muscle, leading to rhythm disturbances.

Some forms of cardiomyopathy, particularly hypertrophic cardiomyopathy, are inherited. Genetic testing or screening may be recommended because of your family history of the condition.

Yes, cardiomyopathy can lead to heart failure, arrhythmias, stroke, and sudden cardiac arrest when untreated.

Life expectancy varies depending on the specific type of cardiomyopathy and the severity of the condition. Most patients with cardiomyopathy can lead everyday lives with proper treatment and management; however, ongoing care is vital for each patient.

Genetic in some instances, but risk factors such as high blood pressure, diabetes, indulging in alcohol, and living a healthy lifestyle can help mitigate the development of cardiomyopathy. Regular check-ups and heart health monitoring are also important.

Most patients with stable cardiomyopathy can travel, but certain precautions are necessary. For example, a healthcare provider can provide personalised travel advice, depending on the severity of the condition, along with medications, emergency contacts, and medical records.

Some hospitals are involved in research and clinical trials for genetic treatments.

International patients are welcome, as are hospitals offering dedicated medical tourism services.

Recovery times vary, but they are generally faster with minimally invasive and catheter-based procedures. Depending on their health status, most patients can resume their normal activities within one to two weeks.
