Heart Diseases in Cats and Dogs – What You Should Know

Many cat and dog parents would be surprised to know that heart diseases are increasingly becoming a common phenomenon amongst pet animals. These might be congenital or acquired, causing significant lifestyle distress in the pet. Understanding their causes, symptoms, and treatments can help you ensure your pet lives a better life.

Types of Heart Diseases in Cats and Dogs 

  • Dilated Cardiomyopathy (DCM): Often seen in large breeds like Dobermans and Great Danes, this condition causes the heart to enlarge and weaken, reducing its ability to pump blood effectively.
  • Mitral Valve Disease (MVD): A common problem of the smaller breeds, MVD affects the heart’s valves, resulting in leakage and improper blood circulation.
  • Hypertrophic Cardiomyopathy (HCM): The most commonly diagnosed heart disease in cats, HCM is characterized by thickened heart walls that limit the heart’s ability to fill and pump blood well.
  • Heartworm Disease: While it is rare in cats, it can be fatal. Heartworms live in the heart and lungs and cause severe damage. Dogs are more at risk, especially in warmer climates or areas where mosquitoes are prevalent.

Recognizing Symptoms

The signs of heart disease in pets are often subtle and mistaken for general fatigue or aging. The earlier these symptoms are recognized, the better the chances of treatment. 

  • Coughing: Persistent coughing, especially after activity or at night, is a red flag, particularly in dogs with heart disease. 
  • Lethargy: A noticeable drop in energy levels or reluctance to engage in physical activity.
  • Rapid or Shallow Breathing: Both cats and dogs can suffer from labored breath or shallowness as their lungs accumulate fluids.
  • Weight Fluctuating: Sudden weight loss or even a bloated abdomen due to fluid retention are can signal heart issues.
  • Fainting or Collapsing: Episodes of fainting, often during exertion, may indicate a lack of oxygen to the brain caused by poor heart function.

To assist pet parents, SAVAVET’s CHF Symptom Checker https://savavet.com/symptomchecker/ offers an easy-to-use tool to help identify potential symptoms of congestive heart failure (CHF) in dogs and cats. Use this tool to understand the warning signs and act promptly.

If you observe any of these symptoms, schedule a visit to your veterinarian immediately. 

Diagnosis of Heart Diseases 

A thorough diagnostic process is essential to identify heart diseases accurately. Your veterinarian may perform: 

  1. Physical Examination: Listening for abnormal heart sounds, murmurs, or irregular rhythms. 
  2. X-rays or Echocardiograms: These imaging tools help visualize the size, shape, and function of the heart.
  3. Electrocardiogram (ECG): Checks for irregularities in heart electrical activity.
  4. Blood Tests: This checks for other diseases that might have caused the heart problems, for example, infections or hormonal imbalances.

The tests help determine the type of condition so that treatment is in the right direction.

Treatment Options

Managing heart disease in pets depends on the severity and specific condition diagnosed. Some conditions can be managed by drugs, while others require more invasive interventions.  There are medications like diuretics, ACE inhibitors, and beta-blockers, among others, which help to regulate symptoms, improve heart function, and reduce fluid retention.

  • Dietary Adjustments: A low-sodium diet can reduce the heart strain as well as the amount of fluid that builds up. Additional diet types should be implemented by veterinarians for more general cardiac care.
  • Surgical Interventions: In some instances, surgical intervention is required; examples of this include removal of heartworms or repair of damaged valves.
  • Lifestyle Changes: Moderate exercise, stress management, and a quiet environment can help significantly in your pet’s health. 

Proper care can ensure that many pets with heart disease live comfortably for many years. 

Prevention of Heart Diseases 

Prevention is always better than cure, and taking proactive measures can significantly reduce the risk of heart disease in your pets:

  • Regular Veterinary Checkups: Routine visits ensure early detection of any potential issues.
  • Heartworm Prevention: Use veterinarian-approved heartworm preventatives, especially if you live in mosquito-prone areas.
  • Healthy Diet: Feed your pet high-quality, balanced food tailored to their specific needs, focusing on maintaining a healthy weight.
  • Weight Management: Obesity can strain the heart, making it more susceptible to disease. Regular exercise and portion control can help keep your pet fit. 
  • Stress-Free Environment: Reduce stressors in your pet’s life, as stress can negatively impact heart health over time. 

Living with a Pet with Heart Disease

When diagnosed with heart disease, pets might get pretty scary to care for. But there are several ways to ensure your pet lives a full, happy life. Keep track of the situation, adhere to medications and diet changes as recommended by your veterinarian, and don’t hesitate to call when needed.

Heart disease in cats and dogs are serious but manageable with early detection and proper care. Advances in veterinary medicine have made it possible to manage these conditions effectively.
