Types of Feline Heart Diseases
When it comes to cat heart problems, there are several types of feline heart diseases that can affect our furry friends. Understanding these conditions is crucial for early detection and proper management. Let’s explore some of the common types of feline heart diseases.
Hypertrophic Cardiomyopathy (HCM)
Hypertrophic cardiomyopathy (HCM) is the most common form of heart disease in cats. It is characterized by the thickening of the left ventricular muscle walls, which can lead to systolic anterior motion of the mitral valve (SAM). SAM can cause temporary blockage, restrict blood flow, and increase pressure within the heart (PetMD). HCM is often an acquired condition and is the most common among all adult feline heart disorders, accounting for almost two-thirds of heart conditions diagnosed in cats. It is diagnosed in 85% to 90% of primary cardiomyopathy cases in cats (Cornell Feline Health Center).
Dilated Cardiomyopathy (DCM)
Dilated cardiomyopathy (DCM) in cats is often attributed to a nutritional deficiency in the amino acid taurine. It leads to the widening of all heart chambers, thinner walls, increased workload of the heart, and loss of contraction strength, ultimately resulting in heart failure (PetMD). Dilated cardiomyopathy is comparatively rare, accounting for only about 1% to 2% of primary cardiomyopathy cases in cats. It is characterized by an enlarged and poorly contracting left ventricle, which leads to weak pumping and reduced blood flow from the heart (Cornell Feline Health Center).
Restrictive Cardiomyopathy (RCM)
Restrictive cardiomyopathy (RCM) in cats involves the heart muscle becoming tough and less flexible. This condition is characterized by a mildly enlarged left ventricle, enlarged atria, and often mitral valve insufficiency.
Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC)
Arrhythmogenic right ventricular cardiomyopathy (ARVC) in cats leads to the right ventricle becoming dilated with thinner walls. This can result in right-sided heart failure.
By understanding these various types of feline heart diseases, cat owners can be better prepared to recognize the signs and symptoms associated with them. Early detection and appropriate treatment are crucial for managing these conditions and ensuring the overall health and well-being of our feline companions.
Symptoms of Feline Heart Disease
Recognizing the symptoms of cat heart problems is crucial for early detection and timely treatment. While some cats may show obvious signs of heart disease, others may not display clinical signs until the disease is advanced. Let’s explore the clinical signs and advanced symptoms to watch for in cats.

Diagnosis and Screening
When it comes to cat heart problems, early diagnosis and screening are vital for effective management and treatment. In this section, we will explore the process of identifying heart disease in cats, the diagnostic measures involved, and the various treatment approaches available.
Identifying Heart Disease in Cats
Cats with heart disease may not display clinical signs until the disease is advanced. Some common signs to watch for include exercise intolerance, withdrawal, hiding under furniture, and increased sleep (VCA Hospitals). However, these signs can also be indicative of other conditions. Therefore, it is crucial to consult a veterinarian for a proper diagnosis.
Regular wellness visits to your veterinarian are essential for early detection of heart disease in cats. During these visits, the veterinarian will perform a thorough physical examination, which includes listening to the heart for any abnormal sounds, such as heart murmurs. They may also measure the cat’s blood pressure and conduct blood tests to screen for heart diseases (Carolina Veterinary Specialists).
Diagnostic Measures
To confirm the presence of heart disease and determine its type and severity, additional diagnostic measures may be necessary. These measures can include:
-
X-rays (radiography): X-rays provide a visual assessment of the heart’s size, shape, and overall condition. They can be helpful in identifying certain abnormalities or fluid build-up in the lungs.
-
Electrocardiogram (ECG or EKG): An ECG measures the electrical activity of the heart and can help identify abnormal heart rhythms (arrhythmias) or other electrical abnormalities.
-
Blood tests: Blood tests are conducted to check for heart muscle damage, assess organ function, and evaluate for conditions such as hyperthyroidism, which can contribute to or mimic heart disease.
-
Echocardiogram: An echocardiogram is a non-invasive test that uses ultrasound to create images of the heart’s structure and function. It provides detailed information about the size of the heart chambers, the thickness of the heart walls, and the function of the heart valves. This test is considered the gold standard for diagnosing heart disease in cats.
Treatment Approaches
The treatment approach for cat heart disease depends on the type and severity of the condition. Many cats with stabilized heart disease can live for many years with proper management and care. However, in some cases, the disease may progress and lead to life-threatening complications (Cornell Feline Health Center).
Treatment options may include:
-
Medications: Medications such as diuretics, beta-blockers, ACE inhibitors, or anti-arrhythmic drugs may be prescribed to manage symptoms, improve heart function, or prevent blood clot formation (cat heart murmur treatment).
-
Dietary considerations: Your veterinarian may recommend a specific diet that supports heart health and addresses any underlying conditions. Some diets are formulated to reduce sodium intake or manage other dietary requirements.
-
Lifelong care: Cats with heart disease require ongoing monitoring and regular follow-up visits to assess their condition, adjust medications if necessary, and address any changes in their health status. It’s important to maintain open communication with your veterinarian and follow their recommendations for the best care of your cat with heart disease.
By promptly identifying heart disease in cats through proper diagnosis and screening, you can ensure timely intervention and increase the chances of managing the condition effectively. Regular veterinary check-ups, along with the appropriate diagnostic measures, play a crucial role in maintaining the heart health of your feline companion.
Congenital Heart Defects in Cats
Congenital heart defects are relatively rare but can affect cats, occurring in approximately one to two percent of kittens. The two most common types of congenital heart disease in cats are malformations of a valve or a septal defect in the heart wall, which can cause turbulence in blood flow and result in a heart murmur. Let’s take a closer look at these specific defects:
Malformations of Heart Valves
Malformations of heart valves are one type of congenital heart defect that can occur in cats. These malformations most frequently involve the mitral valve, which is responsible for ensuring proper blood flow between the left atrium and the left ventricle.
When a valve is malformed, it may not close properly, leading to blood leakage or regurgitation. This can cause turbulence in blood flow, resulting in a heart murmur. The severity of the malformation can vary, ranging from minor abnormalities to more significant structural defects.
Septal Defects in the Heart Wall
Septal defects refer to holes in the septum, which is the membrane that partitions the right and left ventricles of the heart. These holes disrupt the normal separation of oxygenated and deoxygenated blood, leading to improper mixing and potentially affecting the overall efficiency of the heart.
Similar to valve malformations, septal defects can cause turbulence in blood flow and subsequently result in a heart murmur. The size and location of the septal defect can influence the severity of the condition and its impact on the cat’s overall health.
It’s important to note that the presence of a heart murmur does not necessarily indicate a life-threatening condition. However, it is essential to consult with a veterinarian for a thorough examination and diagnosis of the specific heart defect. They can provide guidance on appropriate monitoring, treatment options, and any necessary lifestyle modifications.

Managing Feline Heart Conditions
When it comes to managing feline heart conditions, there are several approaches that can help improve the quality of life for cats with heart disease. This section will cover medications for heart disease, dietary considerations, and lifelong care for cats with heart disease.
Medications for Heart Disease
Cats with heart disease may require medications to manage their condition. Commonly used medications include ACE inhibitors, beta blockers, pimobendan, diuretics, and low-dose aspirin or clopidogrel if blood clotting is a problem (VCA Hospitals). These medications help regulate heart function, reduce blood pressure, and prevent fluid buildup in the lungs.
It’s crucial to follow the instructions provided by the veterinarian when administering medications to a cat with heart disease. Regular examinations and testing are important to monitor the effects of these drugs on the cat’s health. Abruptly stopping the medication can lead to serious adverse effects, so it’s essential to consult with the veterinarian before making any changes to the treatment plan.
Dietary Considerations
While cats with heart disease don’t have specific dietary requirements, maintaining a normal body weight and ensuring adequate levels of taurine in the diet are important. Taurine is an essential amino acid for cats and plays a crucial role in heart health. Commercial cat foods are typically formulated to meet the nutritional needs of cats, including the appropriate levels of taurine.
In some cases, dietary supplementation with vitamin E, Coenzyme Q10, or other medications may be recommended by the veterinarian to support heart health. However, it’s important to consult with the veterinarian before introducing any supplements or making significant changes to the cat’s diet.
Lifelong Care for Cats with Heart Disease
Cats with heart disease require lifelong care and monitoring to manage their condition effectively. Regular veterinary check-ups are crucial to assess the cat’s heart health and make any necessary adjustments to the treatment plan. During these visits, the veterinarian may perform diagnostic tests such as echocardiography or electrocardiography to evaluate the heart’s structure and function.
It’s important to monitor the cat’s weight, breathing patterns, and overall behavior at home. Any changes or new symptoms should be reported to the veterinarian promptly. Cats with heart disease may not display clinical signs until the disease is advanced, so vigilance is key in detecting any potential issues early on.
Creating a stress-free environment for the cat, providing a balanced diet, and ensuring they receive regular exercise appropriate for their condition can also contribute to their overall well-being. By following the veterinarian’s guidance and providing attentive care, cat owners can help their feline companions live comfortable lives despite their heart condition.
