Overview

Hypertrophic cardiomyopathy (HCM) is a genetic heart condition characterised by the thickening (hypertrophy) of the heart muscle, specifically the left ventricle. This thickening can obstruct the blood flow out of the heart, affecting its ability to pump effectively. Also, the left ventricle muscle when thickened results in a decrease blood capacity in the LV. HCM is usually inherited and can lead to symptoms such as chest pain, shortness of breath, and an increased risk of abnormal heart rhythms(due to the change in the arrangement of heart muscles). It is a relatively common cause of sudden cardiac arrest in young people, but individuals with HCM can lead healthy lives with proper management and treatment.

Causes of Hypertrophic Cardiomyopathy

Mentioned below are some of the Hypertrophic Cardiomyopathy causes that help to identify the root issue of the disease:

Genetic Mutations- It is one of the biggest causes of cardiac diseases in general and HCM in particular. The condition thickens the heart's walls, making it difficult for the organ to pump blood. Genes such as MYH7, MYBPC3, TNNT2, TNNI3, and others are involved in the cause of the disease. Genetic mutations are the primary reason for many different medical disorders.
Spontaneous Mutations- HCM may also occur due to spontaneous gene mutations that arise in an individual for the first time without a family history of the condition.
Inherited Pattern- HCM sometimes follow an autosomal dominant inheritance pattern. It means a person has a 50% chance of inheriting the mutated gene from a parent who carries it.
Additional Genetic Factors- Aside from the primary gene mutations, certain genetic factors may influence the development and progression of HCM.
Environmental Factors- Although the primary cause of HCM is genetic, environmental factors such as high blood pressure, excessive alcohol consumption, and certain metabolic disorders may contribute to the condition's development or exacerbate symptoms.
Modifier Genes- Modifier genes can determine the variation in the progression and severity of HCM among affected individuals.

Risk Factors of Hypertrophic Cardiomyopathy

Mentioned below are some of the risk factors for Hypertrophic Cardiomyopathy that make the individual more prone to getting affected by the disease:

Ageing
Family history of the disease
One of the parents affected by the disease

Symptoms of Hypertrophic Cardiomyopathy

Mentioned below are some of the symptoms of Hypertrophic Cardiomyopathy to identify the disease in the initial stages:

Shortness of Breath- Difficulty in breathing is one of the symptoms of this disease. This medical condition occurs due to pressure on the left ventricle of the heart and on the lungs. The affected individual cannot perform high-intensity physical activities. In severe symptoms, the individual may also be unable to perform routine functions.
Chest Pain- Pain in the chest is another symptom of hypertrophic cardiomyopathy. The symptoms of the disease are similar to a heart attack. The patient might feel pain in the chest after performing a high-intensity physical activity. Such activities might pressure the heart, which cannot pump blood to the body.
Swollen Hands and Feet- Swollen hands and feet are one of the symptoms of this disease. The medical condition usually occurs due to atrial fibrillation leading to blood clots and heart failure. In addition, fluid retention also leads to swelling of the hands and legs.

Treatment Options for Hypertrophic Cardiomyopathy

Mentioned below are some of the treatment options for Hypertrophic Cardiomyopathy to cure the disease:

Medications- Hypertrophic Cardiomyopathy medication such as beta and calcium channel blockers help improve the heart's blood flow. The medicines also help to lower the need for oxygen by the heart. The medications also help reduce the obstruction in blood flow and allow the organ to fill blood. Doctors can also advise medicines to improve abnormal heart rhythms.
Low-Intensity Activity- The doctor may advise avoiding high-intensity activity for patients suffering from Hypertrophic Cardiomyopathy. Such activities may pressurise the heart and lead to medical conditions like throbbing and pain in the chest. The patient should perform light and simple exercises to avoid lethargy, which causes heart disease.
Alcohol Septal Ablation- The procedure involves an injection of pure alcohol into the muscle, blocking blood flow from the heart. It helps improve the disease's symptoms and allows patients to perform routine functions hassle-free. The individual may relieve chest pain and improper blood flow.
Implantable Cardioverter-Defibrillator (ICD)- For individuals at high risk of life-threatening arrhythmias or sudden cardiac arrest, an ICD may be recommended. An ICD is a small device implanted under the skin that continuously monitors heart rhythm and delivers electrical shocks to restore normal rhythm if a dangerous arrhythmia occurs.

When to Consult a Doctor

You can also get in touch with the expert cardiology doctors at Narayana Healthcare based in your city to get immediate attention and medical support during injuries, health disorders or any other health concern.

Conclusion

Hypertrophic Cardiomyopathy is a cardiac disease involving improper blood flow due to thickened heart muscle walls. Proper and timely medications can help to lower the symptoms of the disease. In addition, small and positive lifestyle changes help maintain the stability of the procedure performed to eliminate the infection.
