What is cardiomyopathy?
Cardiomyopathy is the general term used for various diseases of the heart muscle. These conditions change the structure of your heart, impacting its ability to pump blood around the body.
Some cardiomyopathy diseases stretch the walls of your heart chambers, making them thinner, while others cause them to thicken or stiffen. These changes make it more difficult for the muscle to effectively pump blood, leading to symptoms such as fatigue, chest pain and swelling in the lower body. Cardiomyopathy can also disrupt the rhythm of your heart, causing cardiac arrhythmia.
Cardiomyopathy conditions can remain stable quite often but sometimes they can worsen over time, although treatment often helps to slow degeneration. Weakening of the heart muscles can eventually lead to heart failure but also increases your risk of other serious conditions such as blood clots and cardiac arrests. However, some cases of cardiomyopathy need no treatment.
According to Cardiomyopathy UK, around 1 in 250 people are affected by heart muscle diseases.
If you're worried that you might have cardiomyopathy, rest assured you've got access to the best cardiac care with HCA UK. We provide rapid testing to get to the bottom of your symptoms and the most effective treatments for cardiomyopathy if you're diagnosed with it.
What causes cardiomyopathy?
The cause of cardiomyopathy isn't always clear or identifiable. However, most heart muscle diseases are either inherited or acquired. Inherited cardiomyopathy is caused by a gene passed down from parent to child, whereas acquired cardiomyopathy is linked to another heart condition or risk factor.
Who's at risk of cardiomyopathy?
Cardiomyopathy is defined as an abnormality of the heart muscle not due to coronary artery disease, valve disease or high blood pressure. It can affect people of all ages but some are more vulnerable to certain types than others depending on various risk factors. There's usually a higher risk of developing cardiomyopathy disease if you have any of the following conditions:
- Cardiac arrhythmia
- Heart inflammation (caused by infection or injury)
- Amyloidosis
- Haemochromatosis
- Muscular dystrophy
- Diabetes
- A family history of cardiomyopathy or unexplained sudden death
Cardiomyopathy risk factors
Other risk factors can also increase your chances of developing cardiomyopathy, including:
- Family history of heart failure or sudden cardiac arrests
- Excessive use of recreational drugs
- Excessive drinking of alcohol
- Obesity
- Nutritional deficiencies
- Pregnancy
- Highly stressful and traumatic experiences (such as bereavement or car accidents)
- Chemotherapy to treat cancer and other forms of radiation

What are the types of cardiomyopathy?
Cardiomyopathy diseases differ depending on how they change the structure of the heart muscle.
Dilated cardiomyopathy (DCM)
This is the most common type of heart muscle disease. Dilated cardiomyopathy develops when the muscles of your left ventricle (one of the chambers in the heart) stretch and become thinner.
The increase in volume in the chamber combined with the weakening of the muscles means your heart is less capable of contracting with enough force to pump blood effectively to the rest of the body.
Dilated cardiomyopathy can affect adults and children but it's more likely to develop in men under the age of 50. It can be inherited or develop as a result of other conditions and is likely to put you at greater risk of heart failure.
Hypertrophic cardiomyopathy (HCM)
With this form of cardiomyopathy, the walls of your heart chambers thicken and the flow of blood through the heart may be obstructed.
The reduction in the size of your heart chambers limits the amount of blood they can hold, affecting how much is pumped around your body. As the muscles thicken, they may not be able to relax properly after contracting, which causes them to stiffen.
Hypertrophic cardiomyopathy can affect all ages and is most commonly inherited from family. Sometimes the condition doesn't produce any symptoms and treatment isn't needed. However, some cases lead to more serious complications such as heart failure, cardiac arrhythmia and heart valve disease.
Arrhythmogenic cardiomyopathy (ACM)
The cells of the heart muscle are joined by proteins. If these are abnormal, they can die and be replaced by scar tissue or fat, which leads to arrhythmogenic cardiomyopathy. This can happen in the left or right ventricle (the latter referred to as ARVC), and is often associated with significant scarring in the heart.
With arrhythmogenic cardiomyopathy, the walls of your heart chambers are weakened or stretched, which makes it harder to pump sufficient amounts of blood around the body. People with this particular condition are much more likely to have heart rhythm problems (arrhythmia).
This cardiomyopathy disease tends to be more common in younger people, although it affects all ages, and is often linked to sudden cardiac events during exercising.
Restrictive cardiomyopathy (RCM)
This is a rare form of cardiomyopathy, more likely to be diagnosed in children although it can affect people of all ages. The muscles of the heart chambers stiffen and become less flexible, meaning they can't relax fully after contracting and don't fill up with blood as much as they should.
The cause of restrictive cardiomyopathy can be difficult to find but it may be a consequence of another condition affecting the heart or be inherited genetically.
Takotsubo cardiomyopathy
Also referred to as 'broken heart syndrome', this rare form of cardiomyopathy is unique in that it emerges after people experience extremely stressful or traumatic events.
It's a temporary heart muscle condition where the left ventricle changes shape and is weakened in response to particular hormones, such as adrenaline, released with stress responses. It's more likely to occur in women but is reversible with treatment and usually leaves no lasting damage.
How is cardiomyopathy diagnosed?
If a doctor suspects you have cardiomyopathy, they'll use one or more of several methods to provide an accurate diagnosis. Common approaches include:
- A consultation and physical exam: Your consultant will ask about your general health, symptoms and any risk factors present. They'll also consider any family history of cardiomyopathy or other cardiovascular conditions. A physical examination, listening to your heart and lungs, and measuring your blood pressure and pulse can detect any initial signs of heart muscle disease.
- Electrocardiogram (ECG) tests: By taking a closer look at your heart rate and rhythm, ECG tests identify any abnormalities in the way your heart is functioning. They can also detect any damage to the heart muscle. There are a few types of ECG that may be required, including normal, exercise and ambulatory/24-hour ECGs.
- Echocardiogram tests: These tests use sound waves to create visual images of your heart and its chambers while beating. With this insight, you can see how the muscles are functioning as well as their size, shape and thickness. Fluid build-up and any valve issues can also be identified.
- Imaging tests: Other imaging tests can provide more comprehensive insight into any cardiomyopathy symptoms. Cardiac MRI and CT scans can generate more detailed images of your heart muscle and its structure, as well as any inflammation, scar tissue or obstructions.
- Blood tests: Analysis of your blood may also be required to check how your body's major organs are functioning and check iron levels. Certain proteins can become more prevalent as symptoms of cardiomyopathy or heart failure emerge.
- Genetic tests: Cardiomyopathy can be an inherited disease. Genetic testing conducted in our state-of-the-art cardiac genetics lab can help to understand more about your condition and potentially inform your treatment.
- Cardiac Biopsy: In very rare cases, a biopsy of your heart may be taken – usually through a catheter inserted in your groin – and sent for analysis. The pressure in your heart chambers can also be measured with the same procedure.
These diagnostic tests aren't just used if you’re having symptoms. If you're at a higher risk or keen to check your heart health, these methods can give you and your consultant further insight.

Cardiomyopathy treatment options
There's generally no cure for cardiomyopathy and inherited forms of the disease cannot be prevented. However, the right treatments and lifestyle changes can help to avoid or manage symptoms and reduce the risk of further complications. Some people don't need treatment for cardiomyopathy.
Lifestyle changes
Changes to your lifestyle can help manage cardiomyopathy symptoms and slow progression or reduce the risk of developing the condition. It generally helps to:
- Exercise regularly (but gently, if you're at greater risk during activity)
- Reduce stress levels
- Get enough sleep
- Eat a healthy and balanced diet
- Maintain a healthy weight
- Avoid smoking
- Avoid recreational drugs
- Avoid or reduce your consumption of alcohol
- Manage any underlying conditions (such as diabetes)
Cardiomyopathy medications
Treatment for cardiomyopathy may start with a combination of medications to lower the risks associated with high blood pressure, abnormal heart rate or rhythm, excess fluid build-up and blood clotting. These should help your heart to function more normally and improve blood flow around your body.
Your consultant may prescribe:
- Blood thinners: Medically known as 'anticoagulants', medicines such as warfarin help to reduce the chances of blood clots forming in your arteries, veins and major organs. They're most commonly used for dilated cardiomyopathy treatment, where the risk of blood clots is higher.
- ACE inhibitors: These medications relax blood vessels to reduce your blood pressure. You might be given enalapril, lisinopril, perindopril or another type of ACE inhibitor.
- Beta-blockers: Medicines such as atenolol and bisoprolol can reduce your heart rate to help lower your blood pressure. They can also treat irregularities in your heartbeat and the symptoms of heart failure.
- Diuretics: Medications such as furosemide help your body release excess salt and water, which can relieve symptoms such as swelling and reduce the workload on your heart.
- Antiarrhythmics: Medications including amiodarone work to correct or prevent abnormal heart rhythms by stabilising its electrical activity.
- Specific tailored treatments: Such as mavacamtem for obstructive hypertrophic cardiomyopathy, which improves blood flow and alleviates symptoms such as shortness of breath and chest pain.
Surgical and non-surgical procedures for cardiomyopathy
In more urgent cases of cardiomyopathy, procedures may be used to provide relief for the heart and prevent further complications.
- Cardioversion or ablation: If you have heart rate or rhythm issues because of cardiomyopathy disease, you may require a procedure to correct the abnormalities. Cardioversion sends electrical signals to your heart through electrodes placed on your chest, while ablation burns or freezes certain areas of heart tissue that are causing the irregularities.
- Septal ablation or myectomy: For those with obstructive hypertrophic cardiomyopathy, treatment may be needed to reduce the size of the wall that divides the left and right side of the heart (septum). A septal ablation uses alcohol to shrink a small part of the septum, while a myectomy involves the surgical removal of some of the enlarged muscle.
- Heart transplants: This is a last resort if other treatments for cardiomyopathy haven't been effective.
Medical device implants
In some cases, you may need a small device implanted in your chest to manage arrhythmias and assist heart function. These can include:
- Pacemakers: These devices control your heart rate by sending electrical signals. A pacemaker is usually implanted under the skin in a procedure done under local anaesthetic.
- Implantable cardioverter defibrillator (ICD): If you have an irregular heart rhythm, ICDs track your heart rhythm and provide controlled electric shocks to prevent you from suffering a cardiac arrest. They're also placed under the skin and can be implanted under local anaesthetic.
- Ventricular assist devices (VAD): These devices help your heart pump blood around the body. VADs can be used as a long-term solution or while you're waiting for a heart transplant, usually only if other less invasive treatments haven't been effective.
Paying for private cardiomyopathy care
Private medical insurance may cover the cost of cardiomyopathy diagnosis and treatment but it’s always worth checking with your insurance provider to confirm if this is the case and whether any conditions apply.
If you’re able to go ahead, mention HCA UK as your preferred provider, plus your chosen consultant’s name if you have one, to ensure you receive the level of care you want.
If you don't have private medical insurance, paying for your own care is also possible. Our private facilities accept most payment methods. We'll send a transparent quote before any care is provided, including the cost of any diagnostics, consultations and necessary cardiomyopathy treatment.
