Cardiovascular: Function, How it Works, and Accompanying Diseases

The heart is a vital organ in the human body whose job is to pump blood throughout the body. Heart muscle assistance is needed so that the process of blood circulation in the body can run optimally

cardiac muscle is a constituent of the heart wall that functions to pump blood, both towards the heart and vice versa, so that blood circulation occurs.

These muscle cells synergize with the heart's nervous tissue to support the regular contraction of the heart. Unlike skeletal muscle which can be controlled consciously, cardiac muscle will continue to work automatically.

Types of Heart Muscle Disease

Because its function is very important in carrying out the work of the heart, it is natural that disturbances in the heart muscle will have a negative impact on blood circulation in the body.

One type of abnormality in the heart muscle is cardiomyopathy. Cardiomyopathy is a condition in which the strength of the heart muscle decreases, so it cannot circulate blood throughout the body optimally.

Cardiomyopathy is divided into four, namely:

1. Dilated cardiomyopathy

Dilated cardiomyopathy is the most common type of heart muscle disorder. This condition occurs when the heart muscle enlarges and stretches, causing the muscle fibers to become thinner and unable to contract properly.

Dilated cardiomyopathy can be inherited genetically or caused by the following conditions:

  • Heart disease
  • Uncontrolled high blood pressure
  • Heart valve disorders
  • Heart attack
  • Infections, such as hepatitis and HIV
  • Long term alcohol and cocaine consumption

2. Hypertrophic cardiomyopathy

Hypertrophic cardiomyopathy occurs due to abnormal thickening of the heart muscle, especially in the left ventricle (chamber) of the heart. This thickening makes the heart muscle unable to pump blood normally.

Hypertrophic cardiomyopathy is a genetic disease that usually runs in families. This disease can develop at any age and can get worse over time.

3. Restrictive cardiomyopathy

Restrictive cardiomyopathy is more common in the elderly. This disease occurs when the heart muscle becomes stiff so that it cannot expand properly. This causes the blood flow to the heart to be reduced or even stopped.

No one knows for sure what causes restrictive cardiomyopathy. However, this condition can be part of other diseases that affect the heart, such as hemochromatosis (accumulation of iron in the body) and connective tissue disease.

4. Arrhythmogenic right ventricular dysplasia (arrhythmogenic right ventricular dysplasia)

This heart muscle disorder is very rare. This disorder arises due to the replacement of the right ventricle of the heart muscle with scar tissue. This change causes the walls of the heart chambers to thin and stretch. As a result, the heart rhythm becomes irregular and cannot circulate blood throughout the body optimally.

Until now no one knows for sure what causes cardiomyopathy. However, there are several conditions that can increase the risk of cardiomyopathy, including:

  • Genetic disorders
  • Family history with heart disease
  • Obesity
  • Vitamin and mineral deficiency
  • pregnancy complications
  • Excessive alcohol consumption
  • Side effects of treatment, such as chemotherapy
  • Drug abuse

Maintaining Heart Muscle He alth

In some cases, cardiomyopathy cannot be prevented, especially if it occurs due to genetic disorders. However, you can still reduce the likelihood of the appearance of symptoms of cardiomyopathy and other types of heart disease by adopting a he althy lifestyle, such as:

  • Limiting consumption of caffeinated and alcoholic beverages
  • Exercise regularly
  • Manage stress well
  • Quit smoking habit
  • Maintain ideal body weight. If you have a history of obesity, it is recommended to adjust your diet and lose weight
  • Implementing a he althy diet regularly by reducing foods that are too sweet, high in s alt, and high in cholesterol
  • Enough rest
  • See your doctor regularly, especially if you have a history of diseases that can trigger cardiomyopathy, such as high blood pressure, high cholesterol, and diabetes

By starting to adopt a he althy lifestyle, you are likely to be able to reduce your risk of developing heart muscle disease and other heart problems.

If you experience shortness of breath, excessive tiredness, chest pain, fast heart rate, and swelling of the legs and body, immediately consult a doctor to get the right treatment. Early treatment is very important to prevent complications.
