Cardiomyopathy: Symptoms, Types, Treatment, And Causes

Cardiomyopathy is a heart condition that makes it harder for the heart to pump blood effectively to the body.

Heart is a vital organ of our body responsible for pumping blood throughout the body. However, sometimes it can be affected by a condition known as cardiomyopathy that weakens and enlarges the heart muscle, making it harder for the heart to pump blood effectively. Cardiomyopathy can lead to serious complications and even heart failure if left untreated. 

What is Cardiomyopathy?

Cardiomyopathy is a condition that impairs the heart muscle's capacity to effectively pump blood, and appears in various ways. There are multiple types of cardiomyopathy, each characterised by unique symptoms and impacting individuals in different ways. However, some general symptoms can indicate the presence of this condition like fatigue, shortness of breath, dizziness, and irregular heartbeats. Swelling of the legs, ankles, and feet is also a common symptom. These signs should not be ignored, as they may indicate an underlying heart condition.

Types of Cardiomyopathy

There are three primary classifications of cardiomyopathy based on the specific area of the heart muscle that is impacted. Here are some of the prevailing types:

  • Dilated Cardiomyopathy (DCM) - DCM is the most prevalent form of cardiomyopathy. It primarily affects the left ventricle, which serves as the heart's primary pumping chamber. In this condition, the left ventricle becomes enlarged and weakened, leading to a reduction in its pumping capacity. This can ultimately result in congestive heart failure. While DCM often has a genetic basis, it can also be triggered by infections, alcohol abuse, or certain medications.
  • Hypertrophic Cardiomyopathy (HCM) - This is characterised by the thickening of the heart muscle, which makes it harder for the heart to relax and fill with blood properly. This condition is typically inherited and can be present at birth or develop later in life. It is a leading cause of sudden cardiac arrest in young athletes.
  • Restrictive Cardiomyopathy (RCM) - RCM is the rarest form of cardiomyopathy and occurs when the heart muscle becomes rigid and less elastic. This impairs the heart's ability to expand and fill with blood, leading to reduced cardiac output. RCM can be caused by diseases such as amyloidosis or sarcoidosis, as well as certain cancer treatments.

Symptoms of Cardiomyopathy

The symptoms of cardiomyopathy can vary depending on the type of cardiomyopathy and how severe it is. Some common symptoms include:

  • Shortness of breath
  • Fatigue
  • Chest pain
  • Swelling in the legs
  • Palpitations (irregular heartbeat)
  • Lightheadedness
  • Fainting

Causes of Cardiomyopathy

Cardiomyopathy can have multiple causes depending on the type of cardiomyopathy. Some common causes include:

  • Genetic Factors - In some cases, cardiomyopathy is inherited and runs in families. Genetic mutations can affect the structure and function of the heart muscle, leading to the development of the condition.
  • Medical Conditions - Certain medical conditions, such as high blood pressure, coronary artery disease, diabetes, thyroid disorders, and obesity, can contribute to the development of cardiomyopathy. Additionally, infections, such as viral myocarditis, can also cause the condition.
  • External Factors - Lifestyle choices and external factors can play a role in the development of cardiomyopathy. Excessive alcohol consumption, drug abuse (particularly cocaine), and certain chemotherapy drugs are known to have cardiotoxic effects that can damage the heart muscle.

Prevention of Cardiomyopathy

There is no sure way to prevent cardiomyopathy, but there are some things you can do to reduce your risk, such as:

  • Quitting smoking
  • Eating a healthy diet
  • Exercising regularly
  • Controlling your blood pressure and cholesterol levels
  • Getting regular checkups with your doctor

Treatment Approaches

Depending on the type and severity of the condition, the treatment of cardiomyopathy varies accordingly. In many cases, a combination of lifestyle changes, medications, and medical procedures is used to manage symptoms and improve heart function.

  • Lifestyle Changes - Patients with cardiomyopathy are often advised to make certain lifestyle modifications. These include adopting a heart-healthy diet, engaging in regular physical activity as recommended by a healthcare professional, quitting smoking, limiting alcohol consumption, and managing stress levels.
  • Medications - Several medications can be prescribed to manage symptoms and improve heart function in cardiomyopathy patients. These may include beta-blockers, ACE inhibitors, diuretics, and antiarrhythmic drugs. The specific medications prescribed will depend on the type and severity of the condition.
  • Medical Procedures - In some cases, medical procedures may be necessary to treat cardiomyopathy. These can range from implanting a pacemaker or defibrillator to restore proper heart rhythm to performing surgical interventions, such as ventricular assist device implantation or heart transplantation in severe cases.


Cardiomyopathy is a complex condition that can have serious implications for one's overall health and well-being. It is crucial to recognize the symptoms and seek medical attention if any signs of heart dysfunction are present. Cardiomyopathy can be managed by understanding its different types, treatment approaches, and causes and taking proactive steps towards maintaining a healthy heart and overall wellness. Remember, your heart is a precious organ, and caring for it should be a top priority.
