Cardiomyopathy

Cardiomyopathy refers to diseases of the heart muscle, where the heart muscle becomes enlarged, thick, or rigid. In rare cases, the muscle tissue in the heart is replaced with scar tissue. As cardiomyopathy worsens, the heart becomes weaker and less able to pump blood through the body and maintain a normal electrical rhythm. This can lead to heart failure or irregular heartbeats called arrhythmias.

Types of Cardiomyopathy

There are several types of cardiomyopathy, each with different causes and characteristics.

Dilated Cardiomyopathy

Diagram showing types of cardiomyopathy.

Dilated cardiomyopathy is the most common form and occurs when the heart's main pumping chamber, the left ventricle, becomes enlarged (dilated) and cannot effectively pump blood out of the heart. This can lead to heart failure and arrhythmias.

Hypertrophic Cardiomyopathy

Histological section of hypertrophic cardiomyopathy.

Hypertrophic cardiomyopathy (HCM) is characterized by abnormal thickening of the heart muscle, particularly affecting the septum between the ventricles. This thickening can obstruct blood flow and cause the heart to work harder to pump blood. HCM is often genetic and can lead to sudden cardiac death, especially in young athletes.

Restrictive Cardiomyopathy

Restrictive cardiomyopathy is the least common type and occurs when the heart muscle becomes rigid and less elastic, preventing the heart from expanding properly and filling with blood between heartbeats. This can lead to heart failure and arrhythmias.

Arrhythmogenic Right Ventricular Cardiomyopathy

Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a rare type of cardiomyopathy that occurs when the muscle tissue in the right ventricle is replaced by scar tissue, leading to arrhythmias and heart failure.

Symptoms

Symptoms of cardiomyopathy can vary depending on the type and severity of the condition. Common symptoms include:

Shortness of breath
Fatigue
Swelling of the legs, ankles, and feet
Irregular heartbeats
Dizziness, lightheadedness, and fainting

Diagnosis

Diagnosis of cardiomyopathy typically involves a combination of medical history, physical examination, and diagnostic tests such as:

Treatment

Treatment for cardiomyopathy depends on the type and severity of the condition and may include:

Medications to manage symptoms and prevent complications
Lifestyle changes such as diet and exercise
Surgical procedures, including implantable devices like pacemakers or defibrillators
Heart transplant in severe cases

Complications

Ventricular fibrillation, a potential complication of cardiomyopathy.

Complications of cardiomyopathy can include:

Heart failure
Blood clots
Valve problems
Cardiac arrest and sudden death

-'''Cardiomyopathy''' refers to a group of diseases that affect the heart muscle ([[myocardium]]), leading to impaired cardiac function. These conditions can result in heart failure, arrhythmias, and other serious complications. Cardiomyopathy can be classified into several types based on the underlying cause and the specific changes in the heart muscle.

 ===Dilated Cardiomyopathy===
-[[File:Dilated cardiomyopathy.jpg|thumb|right|Diagram of a heart with dilated cardiomyopathy]]
-Dilated cardiomyopathy (DCM) is characterized by the enlargement and weakening of the heart's ventricles. This condition often leads to reduced [[ejection fraction]], meaning the heart cannot pump blood efficiently. Causes of DCM include genetic mutations, viral infections, and exposure to toxins such as alcohol or certain chemotherapy drugs.

 ===Restrictive Cardiomyopathy===
-Restrictive cardiomyopathy is characterized by the stiffening of the heart muscle, which restricts the heart's ability to fill with blood. This type is less common and can be caused by conditions such as [[amyloidosis]], [[sarcoidosis]], and hemochromatosis.

 ===Arrhythmogenic Right Ventricular Cardiomyopathy===
-Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a genetic disorder where the heart muscle is replaced by fatty and fibrous tissue, primarily affecting the right ventricle. This can lead to arrhythmias and an increased risk of sudden cardiac death.

+Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a rare type of cardiomyopathy that occurs when the muscle tissue in the right ventricle is replaced by scar tissue, leading to arrhythmias and heart failure.
-Some forms of cardiomyopathy do not fit neatly into the above categories and are considered unclassified. These may include conditions like left ventricular non-compaction and stress-induced cardiomyopathy (also known as Takotsubo cardiomyopathy).
