What is the most common cause of restrictive cardiomyopathy?

Restrictive cardiomyopathy is a rare condition. The most common causes are amyloidosis and scarring of the heart from an unknown cause. It also can occur after a heart transplant.

Restrictive cardiomyopathy

Know the status cardiomyopathy Restricted (Restrictive cardiomyopathy) the names of several other common, such as: cardiomyopathy infiltrative (Infiltrative cardiomyopathy), and cardiomyopathy unknown causes (Idiopathic restrictive cardiomyopathy). Let’s get to know them below:

What is restrictive cardiomyopathy?

Heart disease restricted muscle type is the least common of the many types of case of ill heart (Cardiomyopathy), arise this health problem when they arise a set of changes to the heart, and these changes may lead to lower heart ‘s ability to stretch to accommodate all the amount of blood inside, or may lead Because the heart’s ability to contract naturally.

This condition often arises as a result of hardening of one or both ventricles, and this hardening may arise from a variety of factors and causes, such as: scarring of the heart muscle, and  amyloidosis .

Over time, restricted cardiomyopathy may disrupt the normal blood flow in the heart and disrupt the heart’s ability to pump blood to the rest of the body, which may increase the chances of serious complications, most notably: heart failure and arrhythmias.

Restrictive cardiomyopathy can affect any age group, but it most often affects older adults and, rarely, children. Restrictive cardiomyopathy can be difficult to treat , but there are some treatments that may help improve the condition.

Cardiomyopathy has many other types, such as: dilated cardiomyopathy and hypertrophic cardiomyopathy.

Causes of restrictive cardiomyopathy 

This condition often arises as a result of a type of sclerosis in the ventricles, and this sclerosis may arise as a result of various factors, such as the formation of scar tissue in the heart to gradually replace the normal heart muscle tissue, causing it to harden.

When the walls of the ventricles become hardened, their ability to relax in the normal way decreases, which reduces the ability of the ventricles to absorb the normal amount of blood during the diastole phase, and this defect may also be associated with an enlargement of the atria (Atria).

These are the main causes and factors that may lead to restrictive cardiomyopathy:

  1. Scar tissue builds up in the heart area, as may occur in sarcoidosis .
  2. Amyloidosis, where proteins build up in the heart muscle.
  3. Incidence of disease hemochromatosis (Hemochromatosis), where iron levels rise in the heart of the normal limit.
  4. Undergoing chemotherapy or radiotherapy.
  5. Reasons other factors, such as: injury scleroderma (Scleroderma), and some genetic factors, and the incidence of tumors in the heart area.

In some cases, doctors may not be able to determine the cause of restrictive cardiomyopathy.

Restrictive cardiomyopathy symptoms

In most cases, the patient may not have any symptoms, or only minor symptoms may appear, but in other cases, a group of symptoms may begin to appear on the patient with the worsening of the heart condition and the beginning of the emergence of heart failure, such symptoms:

  • Tiredness and fatigue .
  • fainting.
  • Swelling in the lower extremities.
  • Difficulty doing exercise.
  • Feeling of pressure or pain in the chest area .
  • overweight.
  • Problems related to appetite and digestive system, such as: nausea, bloating, and loss of appetite.
  • apnea
  • heart palpitations ;

It should be noted that the appearance of the following symptoms in particular may mean that the heart failure caused by the condition of restrictive cardiomyopathy has worsened in a way that requires urgent medical intervention:

  1. Rapid heartbeat or irregular heartbeat. 
  2. severe breathing difficulties
  3. A cough accompanied by spitting up pink-colored sputum .

Diagnosis of restrictive cardiomyopathy 

To diagnose restrictive cardiomyopathy, these are some of the medical procedures that may be used:

  • Examine the medical history and medical history of the injured person.
  • Subject the patient to a physical examination.
  • Subjecting the patient to part of the following tests: chest x-ray , heart biopsy, electrocardiogram, echocardiogram, and cardiac catheterization.

Restrictive cardiomyopathy treatment

Restrictive cardiomyopathy can be difficult to treat because the health problems that may have contributed to it can be difficult to treat. The treatment options that the doctor may suggest vary depending on the cause that led to the emergence of the condition, for example:

  • If the cause of the morbidity is excessive iron in the blood, these therapeutic measures may be used: phlebotomy and chelation therapy. 
  • If the disease is caused by amyloidosis, an attempt may be made to treat the condition with a bone marrow transplant.

The following measures may also help keep restrictive cardiomyopathy under control:

  • Follow some lifestyle changes, such as: reducing salt in food, and exercising under the supervision of a doctor.
  • Use of certain types of medications, such as: diuretics, beta-blockers, ACE inhibitors, and blood thinners.
  • Subjecting the patient to a heart transplant in some severe cases.
