Basics of Cardiomyopathy: Concept, Symptoms, and Diagnosis

Cardiomyopathy is a diverse condition of the heart muscle characterized by a disruption of its structure and function. The main symptoms of cardiomyopathy include fatigue, shortness of breath, swelling, and often an irregular heartbeat. Diagnosis often includes electrocardiography, echocardiography, magnetic resonance imaging, and biochemical blood tests. In light of recent medical advancements, various treatment methods, including medication therapy, surgical intervention, and heart transplantation, are significant in managing patients with cardiomyopathy.

Etiology of cardiomyopathy

Cardiomyopathy is a heterogeneous group of diseases of the heart muscle, with various causes, including genetic, acquired, or secondary factors. Genetic mutations can play an important role in the development of cardiomyopathy, as well as factors such as chronic psycho-emotional stress, alcohol and drug intoxication, infections, and autoimmune processes that can contribute to the progression of the disease.

Other causes of cardiomyopathy may include systemic diseases (for example, diabetes), malnutrition, prolonged exposure to toxic substances, and arterial hypertension. It is important to consider the multitude of factors influencing the development of cardiomyopathy for effective diagnosis and treatment of this condition.

  • Genetic mutations: Hereditary predisposition may play a key role in the development of cardiomyopathy.
  • Alcohol and drug poisoning: Long-term use of alcohol or drugs can damage the heart muscle.
  • Infections: Some infections, such as viruses or bacteria, can cause inflammation of the heart muscle.
  • Chronic stress: Prolonged psychological and emotional stress can negatively affect heart health.
  • Systemic diseases: For example, diabetes or autoimmune diseases may be associated with cardiomyopathy.

Clinical picture of cardiomyopathy

The clinical picture of cardiomyopathy can be diverse and depends on the type and stage of the disease. Patients with cardiomyopathy may experience symptoms such as fatigue, shortness of breath, swelling of the lower extremities, chest pain, rhythm disturbances, and palpitations. Some forms of cardiomyopathy may present similarly to ischemic heart disease, while others may manifest as heart dysfunction with preserved left ventricular systolic function. The diagnosis of cardiomyopathy includes clinical examination, electrocardiography, echocardiography, MRI, heart biopsy, and laboratory tests that help determine the type and degree of damage to the heart muscle. Early detection and monitoring of cardiomyopathy symptoms are crucial for effective treatment and management of the disease.

  • Tiredness: one of the common symptoms of cardiomyopathy is a feeling of fatigue and weakness due to reduced cardiac efficiency.
  • Shortness of breath: patients with cardiomyopathy often complain of shortness of breath, which may worsen with physical exertion and in a horizontal position.
  • Swelling of the lower limbs: fluid retention in the tissues, especially in the legs, may be one of the signs of developing cardiomyopathy.
  • Chest pain: patients may experience discomfort or pain in the chest area, which may be caused by a deficiency in ATP production.
  • Rhythm disturbances and palpitations: irregular heart rhythms, the feeling of palpitations, or tachycardia may be symptoms of cardiomyopathy that require further attention and examination.

The specialists’ view on the treatment of cardiomyopathy

Experts in the medical community highlight the importance of an individualized approach to the treatment of cardiomyopathy, depending on its type, stage, and individual characteristics of each patient. The main principles of treatment may include pharmacotherapy, surgical intervention, rehabilitation, and monitoring measures to ensure effective disease management.

Experts also emphasize the significance of a multidisciplinary approach when treating cardiomyopathy, involving physicians from various specialties, physiotherapists, and psychologists. Continuous monitoring of the patient’s condition, regular examinations, and adjustment of treatment are essential for achieving optimal results and improving the quality of life for patients with cardiomyopathy.

Methods for diagnosing cardiomyopathy

Diagnosis of cardiomyopathy includes a wide range of methods, including electrocardiography (ECG), echocardiography (ECHO), magnetic resonance imaging (MRI) of the heart, computed tomography (CT), biopsy of the heart muscle, and laboratory tests. ECG is the primary diagnostic method and can detect abnormalities in heart rhythm and conduction, as well as changes in heart size and structure. ECHO is used to assess heart function, ventricular volumes, and chamber mass. MRI of the heart has high sensitivity and allows for a more detailed examination of the heart’s structure, function, and blood flow.

The use of modern diagnostic methods for cardiomyopathy not only allows for monitoring the effectiveness of treatment but also improves the prognosis of the disease for patients. Some forms of cardiomyopathy may require more specialized diagnostic methods, such as genetic testing or coronary angiography. Early detection and accurate diagnosis of cardiomyopathy using a combination of various methods enable targeted and effective treatment for patients with this heart disease.

  • Electrocardiography (ECG): allows for the assessment of the heart rhythm and conduction, and to identify anomalies in the electrical activity of the heart.
  • echocardiography (EchoCG): a method used to study the structure of the heart, evaluate its function, and identify possible pathologies.
  • Magnetic resonance imaging (MRI) of the heart: provides detailed images of the heart, its valves, and vessels, allowing for the identification of changes in the structure and function of the heart muscle.
  • Computed tomography (CT) of the heart: a method that provides high-quality images of the heart and large vessels, detecting anomalies and pathologies.
  • Myocardial biopsy: a procedure that allows for the collection of a tissue sample from the heart for further examination under a microscope to identify inflammatory or dystrophic changes.

Methods of treating cardiomyopathy

Treatment of cardiomyopathy depends on the type of the disease, the degree of damage to the heart muscle, and the presence of complications. It includes pharmacological therapy, surgical interventions, dilation procedures, and heart transplantation. The goal of treatment is to improve heart function, reduce symptoms, prevent complications, and enhance the quality of life for the patient. Pharmacological treatment includes the prescription of medications aimed at improving the contractile function of the heart, controlling arrhythmias, lowering blood pressure, and managing symptoms.

For some patients with severe forms of cardiomyopathy, surgical treatment may be required, including coronary angioplasty, the installation of a cardioverter-defibrillator, or even heart transplantation. Determining the optimal method of treating cardiomyopathy requires an individualized approach and coordinated efforts from the medical team to achieve the best outcomes for patients.

  • Pharmacological therapy: Includes the use of medications aimed at improving heart contractility, controlling arrhythmias, reducing blood pressure, and managing symptoms.
  • Surgical interventions: May include coronary angioplasty, implantation of a cardio-defibrillator, mechanical heart pumps, or heart transplantation.
  • Dilation procedures: For example, balloon angioplasty to expand blood vessels, as well as stent implantation to maintain artery patency.
  • Physiotherapy and rehabilitation: To improve the overall condition of the patient, strengthen the heart muscle, and restore physical activity.
  • Risk management and lifestyle changes: Includes adherence to a diet, moderate physical exercise, abstaining from harmful habits, and controlling cardiac load.

Measures to prevent cardiomyopathy

Prevention of cardiomyopathy is aimed at reducing the risk of developing this heart condition. Key preventive measures include monitoring blood pressure, maintaining a healthy lifestyle, including a balanced diet, regular physical activity, and avoiding harmful habits such as smoking and excessive alcohol consumption. It is also important to pay attention to risk factors such as genetic predisposition, diabetes, obesity, hypertension, and to conduct timely preventive examinations, including blood pressure measurement, blood tests, and heart condition diagnostics.

Regular monitoring of overall health and seeking medical attention at the first signs of cardiovascular disorders will help identify possible issues in heart function at an early stage and take necessary measures to address them. Adhering to medical recommendations, providing adequate treatment for underlying conditions, and making lifestyle changes contribute to reducing the risk of developing cardiomyopathy and maintaining heart health.

  • Blood pressure control: Regular measurement of blood pressure and maintaining it within normal ranges reduces the risk of developing cardiovascular diseases, including cardiomyopathy.
  • Healthy lifestyle: Proper nutrition with limited fats and sugars, regular physical exercise, and avoiding harmful habits help maintain heart health.
  • Avoiding excessive stress: Constant tension and psycho-emotional overload can negatively affect heart function, so it is important to manage stress and find ways to mitigate it.
  • Following doctor’s recommendations: Rational use of medications, regular monitoring of health status, and following the recommendations of medical professionals can help prevent the onset of heart issues.
  • Preventive examinations: Regular examinations and diagnostics of the heart and blood vessels help identify early signs of disorders and take measures to prevent them.

Amazing aspects of cardiomyopathy
