Hypertrophic Cardiomyopathy (HCM) Description

Hypertrophic cardiomyopathy (HCM) is a condition in which the heart muscle becomes thick, sometimes only in one part of the heart. This thickening can lead to obstruction of blood flow and other complications.

• Thickened Heart Muscle: The heart muscle cells enlarge more than normal, causing the heart walls to become thicker.
• Obstruction of Blood Flow: The thickened heart muscle can block or slow down blood flow from the left ventricle to the aorta, leading to symptoms such as chest pain and shortness of breath.

According to [4], HCM is a condition in which the heart muscle becomes thick, sometimes only in one part of the heart. This description highlights the key characteristic of HCM, which is the thickening of the heart muscle.

Common Signs and Symptoms of Hypertrophic Cardiomyopathy

Hypertrophic cardiomyopathy (HCM) can manifest in various ways, and it's essential to be aware of the possible symptoms. According to recent medical research [4], among people who develop symptoms, the most common complaints include:

• Chest pain
• Shortness of breath with exertion
• Fatigue
• Palpitations

These symptoms are often more pronounced during physical activity or exercise. It's crucial to note that some individuals may not experience any symptoms at all, while others may only feel them with exertion [2]. If you're experiencing any of these symptoms, it's essential to consult a healthcare provider for proper evaluation and treatment.

Additional Symptoms

Other possible symptoms of HCM include:

• Dizziness
• Fainting spells (syncope)
• Abnormal heart rhythms (arrhythmias)

It's worth noting that some people may not experience any symptoms in the early stages of the disease, but they can develop them over time [2]. If you have a family history of HCM or are experiencing any of these symptoms, it's essential to consult a cardiologist for proper evaluation and treatment.

Diagnostic Tests for Hypertrophic Cardiomyopathy (HCM)

Hypertrophic cardiomyopathy (HCM) can be diagnosed through several diagnostic tests, which are essential in confirming the presence of this condition. The following tests are commonly used to diagnose HCM:

• Echocardiogram: This is a non-invasive test that uses sound waves to create images of the heart muscle and blood flow. It helps to measure the thickness of the left ventricular wall, which is a key indicator of HCM ([4], [5]).
• Electrocardiogram (ECG): An ECG measures the electrical activity of the heart and can detect abnormal heart rhythms that may be associated with HCM.
• Genetic Testing: Genetic testing can be done from a blood sample to diagnose HCM, providing information about prognosis and family risk ([6]).
• Magnetic Resonance Imaging (MRI): MRI is another imaging test that can help diagnose HCM by creating detailed images of the heart muscle and blood flow.
• Exercise Test: An exercise test may be performed to assess how the heart responds to physical activity.

These diagnostic tests are essential in confirming the diagnosis of hypertrophic cardiomyopathy and determining the best course of treatment.

Treatment Options for Hypertrophic Cardiomyopathy (HCM)

According to recent studies, there are limited treatment options available for hypertrophic cardiomyopathy (HCM). One disease-specific medication that has been approved for the treatment of HCM is Mavacamten.

Mavacamten is a novel therapeutic agent that has shown promise in reducing left ventricular outflow tract obstruction and improving symptoms in patients with obstructive HCM. This medication works by inhibiting the activity of cardiac myosin, which helps to reduce the thickness of the heart muscle and improve blood flow.

While Mavacamten represents a significant advancement in the treatment of HCM, it is essential to note that this medication may not be suitable for all patients with HCM. The decision to use Mavacamten should be made on an individual basis, taking into account the patient's specific symptoms, medical history, and overall health.

Other Treatment Options

In addition to Mavacamten, other treatment options for HCM may include:

• Genetic counseling to identify the underlying cause of the condition
• Lifestyle modifications, such as regular exercise and a healthy diet, to manage symptoms and improve quality of life
• Cardiac rehabilitation programs to help patients recover from heart-related events or procedures

It is crucial to consult with a healthcare professional for personalized advice on managing HCM.

The differential diagnosis of apical Hypertrophic Cardiomyopathy (HCM) includes:

• Mural thrombus
• Hypertrabeculation or non-compaction
• Endomyocardial fibrosis

These conditions can present with similar echocardiographic features to apical HCM, making differential diagnosis challenging. A thorough clinical evaluation and additional diagnostic tests may be necessary to confirm the correct diagnosis.

According to [4], these conditions should be considered in the differential diagnosis of apical HCM, highlighting the importance of a comprehensive approach to diagnosis.

Additionally, it's worth noting that systemic hypertension and aortic stenosis are also common causes of acquired left ventricular hypertrophy, which can mimic the echocardiographic features of HCM [6].
