Heart disease in cats is a significant health issue that can affect cats of all ages and breeds. Recognising the signs and understanding the different types of heart disease in cats can help in early diagnosis and treatment, improving the quality of life for your cat.

What is Heart Disease in Cats?
Heart disease in cats refers to any condition that affects the heart's ability to function properly. This can include structural abnormalities, problems with the heart muscle, or issues with the heart's electrical system.
These conditions can lead to serious health problems and, if not managed properly, can be life-threatening.
Some common forms of heart disease in cats include congenital defects present at birth and adult-onset diseases like hypertrophic cardiomyopathy, where the heart muscle thickens, making it difficult for the heart to pump blood effectively.
Breeds Most at Risk
Certain breeds are more likely to develop heart disease. These breeds include:
Maine Coon
Siamese
Persian
Ragdoll
British Shorthair
Life Expectancy of a Cat with Heart Disease
The life expectancy of a cat with heart disease varies based on the type and severity of the condition, as well as how early it is diagnosed and treated. With proper management, including medication, diet, and regular veterinary care, many cats with heart disease can live several years with a good quality of life.
It's important to work closely with your vet to monitor your cat’s condition and make any necessary adjustments to their care plan.
Types of Heart Disease in Cats
Congenital Heart Disease
Congenital heart disease in cats means the cat is born with the condition. This can include a variety of structural problems in the heart, such as patent ductus arteriosus (PDA), where a blood vessel doesn’t close properly after birth, and ventricular septal defects (VSD), which are holes in the heart’s walls. These issues can arise due to genetic factors or problems during development before birth.
Adult-Onset Heart Disease
Heart disease that develops later in life is called adult-onset heart disease in cats. The most common form is hypertrophic cardiomyopathy (HCM), where the heart muscle becomes too thick, making it hard for the heart to pump blood effectively.
Other types include dilated cardiomyopathy (DCM), where the heart becomes too stretched out, and restrictive cardiomyopathy (RCM), where the heart becomes too stiff.
Symptoms of Heart Disease in Cats
Cats with heart disease might show symptoms that can often be subtle and easily missed. Common signs include:
Changes in Appetite and Weight: Cats might eat less or lose weight suddenly.
Lethargy: They might seem unusually tired and less willing to play or move around.
Respiratory Issues: Cats may have trouble breathing, cough, or breathe rapidly.
Sudden Collapse: In some cases, cats might faint or collapse suddenly due to poor blood flow to the brain.
Diagnosing Heart Disease in Cats
Initial Examination and Detection
Regular vet check-ups are crucial for catching heart disease early. Vets can spot initial signs such as unusual heart sounds or irregular heartbeats during routine exams, which can prompt further testing.
Advanced Diagnostic Methods
To get a detailed diagnosis, vets may use X-rays to look at the heart, electrocardiograms (ECGs) to track the heart's electrical activity, and echocardiography, which is an ultrasound of the heart to see its structure and function clearly. These tests help vets understand the condition better.
Treatment Options for Heart Disease in Cats
Medical Management
Treating heart disease in cats often involves medications that help manage symptoms and improve heart function:
ACE Inhibitors: These medications help relax blood vessels, making it easier for the heart to pump blood. This reduces the heart's workload and can help prevent further damage.
Beta-Blockers: These drugs reduce the heart's workload by slowing down the heart rate and lowering blood pressure.
Diuretics: Also known as "water pills," diuretics help remove excess fluid from the body. This is particularly helpful if the cat's heart disease has led to fluid buildup in the lungs or other areas.
Surgical Interventions
In some cases, surgery might be needed to fix congenital (present from birth) heart problems.
For example, Patent Ductus Arteriosus (PDA) is a condition where a blood vessel that should close after birth remains open. Surgery can correct this and prevent any further complications in your cat.
Surgery is typically considered when medications alone aren't enough to manage the condition. Your vet will guide you on the best treatment options based on your cat's specific needs.
Managing Heart Disease in Cats at Home
Diet and Nutrition
Diet and nutrition play a crucial role in managing heart disease in cats. Maintaining an optimal weight is essential as obesity can exacerbate heart problems.
Special diets may be recommended to support heart health, often including taurine, an amino acid vital for heart function.
Low-sodium diets help reduce fluid retention and decrease the heart's workload. Ensuring your cat gets balanced nutrition with the right vitamins and minerals can improve their overall health and quality of life.
Always consult your vet for specific dietary recommendations tailored to your cat's condition.
Medication Administration
It’s crucial to follow your vet’s instructions on giving medications. Monitor your cat for any side effects and regularly consult with your vet to adjust treatment plans as needed.
Some common side effects of heart disease medication include:
Low blood pressure
Kidney dysfunction
Gastrointestinal upset
Lethargy
Slow heart rate
Dehydration
Weakness
Promoting Heart Health in Cats
Understanding heart disease in cats—from types and symptoms to diagnosis and treatment—can greatly enhance the care and management of affected pets. Early detection and proper treatment are key to ensuring a healthier and longer life for your cat.
Regular vet check-ups and attentive care at home can make a significant difference. Always consult your vet for the best approach to managing heart disease in cats.
