Dilated Cardiomyopathy

Dilated Cardiomyopathy is the disease of the heart muscle that starts in the left ventricle of the heart and due to this the left ventricle becomes thin and cannot pump blood.

Dilated Cardiomyopathy refers to a health disease that causes problems in the blood circulation of the body. Heart ventricles are affected by the disease and due to the left ventricle becoming thin and dilated that cannot pump blood from the heart chamber to the whole body. A common cause of heart attack and heart block is Dilated Cardiomyopathy. Shortness of breath, fatigue and breathing problems are the common symptoms of Dilated Cardiomyopathy. It can affect the other organs like the liver and lungs due to the blockage of blood from the heart chamber to the body.

Definition:

Heart disease caused by the blockage of coronary arteries and narrowing of ventricles is called Dilated Cardiomyopathy. Poor control of high blood pressure increases the risk factor for this disease. Food containing trans fat, junk food consumption, and consumption of toxic compounds are also responsible for increasing dilated Cardiomyopathy in the human body. Medicines containing steroids and drugs for treating cancer also affect the heart muscle and increase the risk factor for this disease. It is the most common type of heart disease that occurs mainly among the age groups of 20-60 years people. 

Dilated Cardiomyopathy Symptoms:

  • Swell in the legs, shortness of breath, reduction of ability to exercise, chest pain, and fast breathing is the major symptoms of Dilated Cardiomyopathy
  • The unusual sound of the heart and chronic breathing problems, and reduction of metabolic rate 
  • Dizziness, fainting during physical activity and acute pain in the left ventricle of the heart 
  • The ability of the heart to pump blood through the left ventricle to the body decreases due to this disease

Treatment:

  • Echocardiogram, ECG, chest X-ray, and Cardiac catheterisation are the most common disease diagnosis processes to determine the ability of the heart in pumping blood through the ventricles
  • CT scans and MRI scans have been developed to determine the function of the coronary arteries and their effects on blood circulation.
  • Myocardial biopsies are also useful for determining the cause of Cardiomyopathy
  • Angiotensin-Converting Enzyme (ACE) drugs are proved to be beneficial for the treatment of this patient, physical diagnosis helps in the quick diagnosis of disease and reduces the health effect

Causes of Dilated Cardiomyopathy:

  1. Infection due to viruses and parasites increases the chance of the disease due to the blockage of the heart ventricle.
  2. Dietary intake of junk food, high-fat food, salted food, oil-rich food and toxic food increases the risk factor for the disease
  3. Amphetamines and steroid drugs often damage the heart ventricles and cause Dilated Cardiomyopathy
  4. Diabetes, thyroid and hepatitis are the most common cause of the Dilated Cardiomyopathy
  5. Exposure to the chemical toxins and heavy metals like lead, sulfur, cadmium inhibits the breathing problem and causes Dilated Cardiomyopathy

Disease-Associated with Dilated Cardiomyopathy:

Ischemic heart attack, blood clots in the muscle, unnecessary breathing and palpitation, and vitamin-D deficiency are the disease that is associated with the complication of Dilated Cardiomyopathy. Lung failure and liver dysfunction are the two major diseases associated with heart disease. Hypocalcemia leads to heart failure and heart attack as calcium is essential for the contraction of myocardial muscle. Hypertrophic Cardiomyopathy causes acute pneumonia due to shortening of breath and lungs failure. Thickening of heart muscle increases the risk for restrictive Cardiomyopathy and heart muscles become scars.

Types of Cardiomyopathies:

  1. Different types of Cardiomyopathies cause health damage in the human body Dilated Cardiomyopathy, restrictive Cardiomyopathy, hypertrophic Cardiomyopathy, left ventricular dysplasia and amyloid Cardiomyopathy. 
  2. Restrictive Cardiomyopathy occurs when the heart chambers become stiff and it is not able to become normal between the heartbeats. This type of myopathy occurs due to the construction of scar tissues in the bloody chamber. Building up abnormal protein also resulted in Cardiomyopathy. Chemotherapy or exposure to UV rays increases the risk factor for this disease.

Conclusion

The above study indicates that heart attack is increased due to an unhealthy diet and diabetes in the body. Dilated Cardiomyopathy is a disease caused due to hypothyroid, diabetes and hypertension. The study indicates that dizziness and shortening of breath are the most common symptoms of this disease. Cardiomyopathy leads to systemic heart failure and affects the lung’s function in the body. Heredity also increases the risk for the disease and daily workout is the main activity that can reduce the risk of the disease. The study also illustrates that consumption of toxic compounds and exposure to the chemical toxin increases risk factors for the disease.
