4 Types of Weak Hearts You Need to Know
Windowofworld.com – Weak heart is a disorder in the heart muscle that causes the heart cannot pump blood optimally or it is difficult to maintain its normal rhythm. There are various types of weak heart that have different causes and symptoms.
In a weak heart or cardiomyopathy, there are disorders that cause the heart muscle to become thinner, thicker, or stiffer. This condition makes the heart pump weakened and causes a number of symptoms, such as shortness of breath, swollen feet due to fluid buildup, irregular heart rhythm, dizziness, or fainting.
These Are Kinds of Weak Hearts
Different types of weak heart, also different symptoms that arise. So you can be alert, consider the following explanation about the types of heart weakness and its causes and symptoms.
1. Weak type dilated heart
This is the most common type of weak heart. Weakened type of dilated heart usually attacks people aged 20-60 years, and sufferers have a high risk for heart failure.
This type of heart muscle disorder often starts in the left ventricle of the heart, which is the heart chamber which has a role to pump blood throughout the body. In a weak heart type dilated, the left ventricular muscle gradually becomes thinner and sagging, so the ventricular chamber widens and it is difficult to pump blood. In addition, the right ventricle and heart atrium can also be disturbed.
Dilated heart type is usually caused by:
- Coronary heart disease and heart attack
- High blood pressure (hypertension)
- Thyroid disease and diabetes
- Certain viral infections that cause inflammation of the heart muscle
- Excessive alcohol consumption
- Pregnancy complications
- Toxins, such as cobalt or certain drugs
2. Hypertrophic type weak heart
In this type of weak heart, the heart muscle cells in the left ventricle enlarge, so the ventricular wall becomes thicker and the room inside it narrows.
This condition decreases the amount of blood pumped throughout the body because the heart muscle is stiffer so the pumping is weak and the narrow left ventricular space can only hold a little blood for pumping. In addition, the heart muscle that is too thick can block or close the blood flow.
Hypertrophic type of weak heart is often caused by abnormal genes in the heart muscle cells. Symptoms that often appear include chest pain, shortness of breath, fatigue, edema in the leg area, dizziness, or fainting. Symptoms can continue to worsen over time and cause fatal complications, such as heart rhythm disorders (arrhythmias) and sudden death.
3. Weak heart type ARVD
Arrhythmogenic right ventricular cardiomyopathy (ARVD) is a weak type of heart characterized by the death of heart muscle cells in the right ventricle. The cells are then replaced by scar tissue or fat tissue. This condition can disrupt the heart’s electrical current which causes arrhythmias.
ARVD is common in teenagers or young adults. This type of weak heart is thought to be caused by mutations in certain genes inherited from parents. Symptoms that can appear in the form of heart palpitations (palpitations) or fainting after the sufferer doing physical activity.
Several studies have shown that heavy exercise can worsen ARVD symptoms. This type of weak heart is a major cause of sudden death in young athletes due to cardiac arrest.
4. Weak restrictive heart type
Of the types of weak heart, this type is the most rare. In restrictive-type heart weakness, the heart muscles become stiffer and less elastic. As a result, the heart cannot relax normally after contracting. This causes blood to not be able to fill the heart chamber perfectly.
The cause of restrictive heart weakness is often unknown. However, some cases of this type of weak heart are triggered by other diseases, such as:
- Hemochromatosis, which is excessive buildup of iron in the body
- Sarcoidosis, an abnormal buildup of inflammatory cells in the body’s organs
- Amyloidosis, which is a buildup of abnormal proteins in body tissues
- Cancer that is being treated with chemotherapy or radiotherapy
Weak heart that is not caused by other diseases, including heart weakness that is genetically inherited from parents, is called primary heart weakness. Whereas weak heart caused by other diseases, such as high blood pressure, coronary heart disease, infections, toxins, or side effects of certain drugs, is called secondary heart weakness.
In addition to the types of heart weakness that have been mentioned above, there are actually other types of heart weakness that are not classified, but are very rare. If you experience symptoms of a weak heart, consult a doctor immediately. That way, treatment can be given as soon as possible before fatal consequences occur.
