Question: what is cardiomyopathy?

Cardiomyopathy is a progressive disease of the myocardium, or heart muscle. In most cases, the heart muscle weakens and is unable to pump blood to the rest of the body as well as it should.
There are many different types of cardiomyopathy, caused by a range of factors, from coronary heart disease to certain drugs. Cardiomyopathy can lead to an irregular heartbeat, heart failure, or other complications.
Medical treatment and follow-up care are important. They can help prevent heart failure or heart damage.
This article will take a closer look at the types of cardiomyopathy, as well as the symptoms, causes, and treatment.

Question: What are the usual symptoms of cardiomyopathy?

The symptoms of all types of cardiomyopathy tend to be similar. In all cases, the heart can't adequately pump blood to the tissues and organs of the body. It can result in symptoms such as:
general weakness and fatigue
shortness of breath, particularly during exertion or exercise
lightheadedness or dizziness
chest pain
heart palpitations
fainting spells
high blood pressure
a bloated abdomen
coughing when lying down
edema, or swelling, of your feet, ankles, legs, or other body parts

Question: causes of cardiomyopathy?

According to the National Heart, Lung, and Blood Institute
, the cause of cardiomyopathy is often unknown. In other cases, the cause can either be inherited or acquired:
'Inherited' means that you're born with cardiomyopathy due to the genes you inherited from your parents.
'Acquired' means that you developed cardiomyopathy due to a health condition, disease, or some other type of illness during the course of your life, such as:
coronary artery disease
heart tissue damage due to a heart attack
infections in the heart muscle

Question: What are the potential risk factors associated with cardiomyopathy?

Cardiomyopathy can affect people of all ages. Major risk factors include:
a family history of cardiomyopathy, sudden cardiac arrest, or heart failure
coronary artery disease
chronic (long-term) high blood pressure
damage to the heart due to a heart attack
infections that cause inflammation of the heart
heart valve disorders
COVID-19 infection
diabetes
obesity
thyroid disease
alcohol use disorder
sarcoidosis
hemochromatosis
amyloidosis
connective tissue disorders
use of cocaine or amphetamines
some types of cancer medications
exposure to toxins, such as poison or heavy metals
According to 2016 research
, HIV and HIV treatments can also increase your risk of cardiomyopathy. HIV can increase your risk of heart failure and dilated cardiomyopathy, in particular.
If you have HIV, talk with a doctor about getting regular tests to check your heart's health. You should also try to follow a heart-healthy diet and exercise program.

Question: How do doctors usually figure out if someone has cardiomyopathy, diagnosis?

Your doctor or cardiologist will incorporate the results of four components into your diagnosis:
your personal medical history
your family medical history
physical examination
diagnostic tests and procedures
The diagnostic tests and procedures your doctor or cardiologist may use include:
Blood tests. Blood tests can provide information about your heart and also help rule out other conditions.
Chest X-ray. A chest X-ray can help your doctor see the size and structure of your heart and lungs and check for any fluid buildup.
Stress test. A stress test gauges your heart function while you exercise.
Electrocardiogram. An electrocardiogram (EKG or ECG) is used to assess your heart's electrical activity over a short period of time.
Holter monitor. A Holter or event monitor can measure your heart's electrical activity over 24 or 48 hours.
Echocardiogram. An echocardiogram uses sound waves to create live images of your heart and how it's beating.
Heart MRI. A heart MRI uses magnets and radio waves to capture images of your heart and coronary blood vessels.
Your doctor may also perform some diagnostic procedures to confirm the diagnosis, especially if you're planning to have surgery. These procedures may include:
Cardiac catheterization. With cardiac catheterization, a long, thin tube is inserted into an artery or vein and threaded up to your heart so your doctor can evaluate your heart for a number of potential issues, including artery blockages.
Coronary angiography. With coronary angiography, your doctor injects dye into your bloodstream to look at the flow of blood through your arteries and heart.
Myocardial biopsy. A myocardial biopsy is a procedure that involves removing a small part of your heart's tissue so it can be examined under a microscope.

Question: What are the ways to prevent cardiomyopathy?

If cardiomyopathy runs in your family, you may not be able to completely prevent it. But, you can take steps to keep your heart healthy and minimize the impact of this condition.
Even if cardiomyopathy isn't part of your family history, it's still important to take steps to make sure you don't develop a heart condition or disease that could put you at an increased risk of cardiomyopathy.
The steps
you can take to help lower your risk of cardiomyopathy include:
Getting regular exercise. Try to limit how much you sit each day, and focus on getting at least 30 minutes of exercise most days of the week.
Getting enough sleep. Sleep deprivation is linked to an increased risk of heart disease. Try to get at least 7 to 8 hours of sleep each night.
Eating a heart-healthy diet. Try to limit your intake of sugary, fried, fatty, and processed foods. Focus instead on fruits, vegetables, whole grains, lean proteins, nuts, seeds, and low fat dairy. Also limit your intake of salt (sodium), which can raise your risk of high blood pressure.
Reducing your stress levels. Try to find healthy ways to lower your stress when possible. You may want to consider taking regular brisk walks, doing deep breathing exercises, meditating, doing yoga, listening to music, or talking with a trusted friend.
Quitting smoking, if you smoke. Smoking can negatively affect your entire cardiovascular system, including your heart, blood, and blood vessels.
Managing underlying health conditions. Work closely with your doctor to control and manage any underlying health conditions that may raise your risk of cardiomyopathy.
