Understanding cardiomyopathy can help you find the right treatment
Cardiomyopathy is a collection of conditions that affect the heart muscle and reduce the heart’s ability to pump blood effectively. Up to 1 in 500 adults may have the condition, but it often goes undiagnosed.
All cardiomyopathies interfere with blood flow from the heart to the rest of the body. But the exact issue with pumping blood out of the heart can differ. Possible problems include:
- Heart muscle scarring or stiffening
- The heart filling with a substance other than blood
- Thickening or thinning of the heart muscle
These issues may lead to Insuficiencia cardiaca or sudden cardiac arrest, where the heart stops pumping unexpectedly.
Types of cardiomyopathies
-
Arrhythmogenic cardiomyopathy
Arrhythmogenic cardiomyopathy
This type causes irregular heartbeat or rhythm (Arritmia).
-
Miocardiopatía dilatada
Miocardiopatía dilatada
One of the two lower heart chambers responsible for pumping blood is enlarged.
-
Hypertrophic cardiomyopathy
Hypertrophic cardiomyopathy
This type involves the thickening of the heart muscle.
-
Peripartum cardiomyopathy
Peripartum cardiomyopathy
A rare type of heart failure, peripartum cardiomyopathy happens late in pregnancy or within a year of giving birth.
-
Miocardiopatía restrictiva
Miocardiopatía restrictiva
This occurs when the heart muscle becomes scarred or stiff.
-
Takotsubo cardiomyopathy
Takotsubo cardiomyopathy
Also called broken heart syndrome, this type happens in response to extreme stress.
-
Transthyretin amyloid cardiomyopathy
Transthyretin amyloid cardiomyopathy
This type happens when a specific protein builds up in the heart.
Arrhythmogenic cardiomyopathy
This type causes irregular heartbeat or rhythm (Arritmia).

Cardiomyopathy symptoms
Some people never experience symptoms of this condition. In others, cardiomyopathy symptoms may appear or worsen as the condition progresses.
Possible cardiomyopathy symptoms include:
- Angina (Dolor de pecho), especially after physical activity or eating a large meal
- Arritmia
- Cansancio extremo
- Mareos o aturdimiento
- Desmayo
- Dificultad para respirar o dificultad para respirar
- Swelling in the abdomen, ankles, feet or legs
What causes cardiomyopathy?
The cause of cardiomyopathy is often unknown, but several possible factors can be involved, including:
- Enfermedad coronaria
- Extreme stress
- Genética
- Health conditions that damage the heart muscle
- Ataques al corazón
- Alta presion sanguinea
- El embarazo
- Infección viral
Cardiomyopathy risk factors
Cardiomyopathy can affect people of all ages, but some types are more common at certain stages of life. For example, arrhythmogenic cardiomyopathy often affects teens or young adults. In contrast, hypertrophic cardiomyopathy is more likely to affect people in their 30s.
Similarly, certain types are more common in men, and others tend to affect women.
You may be at higher risk for cardiomyopathy if you have any of the following risk factors:
- Diabetes
- Family history of cardiomyopathy, heart failure or sudden cardiac arrest
- Altos niveles de estrés
- History of Quimioterapia or radiation treatments
- Infection in the heart muscle
- Obesidad
- Regular alcohol use
- Enfermedad de tiroides
- Use of illegal drugs such as cocaine or methamphetamines
Diagnosing cardiomyopathy
-
Análisis de sangre
Análisis de sangre
Blood tests measure for specific proteins in the blood that help keep blood pressure stabilized.
-
Electrocardiograma (EKG o ECG)
Electrocardiograma (EKG o ECG)
An electrocardiogram tracks the electrical signals in the heart to monitor its health and functionality.
-
Pruebas de imagen
Pruebas de imagen
Imaging tests like coronary angiograms take X-rays of the heart’s blood vessels to scan for blockages.
-
Genetic testing or screening
Genetic testing or screening
You may have access to genetic counseling programs that can help assess your likelihood of having an increased risk of cardiomyopathy. Talk to your doctor to see if this is an option for you.

Cardiomyopathy treatment options
Some types of cardiomyopathy don’t require treatment if they aren’t causing symptoms. Certain kinds may also go away on their own.
If you need treatment for your cardiomyopathy, your cardiologist will work with you to develop a care plan to:
- Mejore su calidad de vida
- Keep the condition from worsening
- Manage symptoms
- Prevent serious complications, including sudden cardiac arrest
- Treat an underlying health condition causing cardiomyopathy
Depending on the type of cardiomyopathy you have, treatment might include a combination of lifestyle changes, medication, medical procedures or surgery.

Cambios en el estilo de vida
Cambios en el estilo de vida
You may be able to manage certain types of cardiomyopathy with lifestyle changes, such as:
- Avoiding alcohol and illegal drugs
- Llevar una dieta saludable
- Hacer ejercicio regularmente
- Dormir lo suficiente
- Limiting certain activities
- Learning new ways to manage stress
- Taking steps to manage chronic health conditions
- Dejar de fumar
-
Medicación
Medicación
Your cardiologist may recommend medication to manage or treat cardiomyopathy, including prescription drugs that:
- Balance minerals in the body (called electrolytes)
- Decrease inflammation
- Presión sanguínea baja
- Prevent blood clots
- Remove excess fluid
- Slow heart rate
-
Cirugía y procedimientos
Cirugía y procedimientos
When cardiomyopathy can’t be treated through lifestyle changes and medication, your cardiologist may recommend a medical procedure or surgery, such as:
- Alcohol septal ablation: During this nonsurgical procedure, a type of alcohol is injected into a blood vessel that brings blood to the heart. The alcohol causes the muscle dividing the lower heart chambers to shrink, improving blood flow.
- Catheter ablation: This nonsurgical procedure uses extreme temperatures, laser light or radiofrequency waves to reroute electrical signals in the heart.
- Septal myectomy: During this open-heart surgery, your surgeon removes a part of the muscle dividing the lower heart chambers to improve blood flow.
- Surgery to implant a device: Medical devices, such as a cardioverter defibrillator, left ventricular assist devices and pacemakers, can improve how your heart works by monitoring your heart rate or managing your heart rhythm.
- Transplante de corazón: Generally used only for people with life-threatening complications, you may need a Transplante de corazón if the treatments above aren’t successful.
