Heart Disease Treatments for Pets

Persistent Coughing

Especially after activity or at night, which may indicate fluid build-up in the lungs.

Difficulty Breathing or Rapid Breathing

Laboured or faster-than-normal breathing can signal that the heart is not pumping efficiently.

Reduced Energy or Exercise Intolerance

Pets may tire easily or avoid activities they once enjoyed.

Loss of Appetite or Weight Loss

Changes in eating habits may occur as the condition progresses.

Swollen Abdomen

Fluid accumulation in the abdomen may cause visible bloating.

Fainting or Collapse

Sudden episodes can occur due to poor circulation or abnormal heart rhythms.

Restlessness or Discomfort

Especially when lying down, as pets may struggle to settle comfortably.

What Treatments Are Available for Pets with Heart Disease?

The approach to treating heart disease depends on the specific condition, its severity and the overall health of your pet. A veterinarian will recommend a combination of the following modalities to stabilise the condition and improve your pet’s well-being:

Medication Therapy

Medication is often the first line of treatment for heart disease in pets. The goal is usually to reduce the workload on the heart, control irregular heartbeats and prevent fluid build-up in the lungs and abdomen. Common types of medications include:

• Diuretics: These help the kidneys remove excess fluid from the body, which relieves pressure on the heart and lungs.
• ACE Inhibitors: These drugs widen blood vessels, making it easier for the heart to pump blood forward and lower blood pressure.
• Inotropes: These help the heart muscle contract with more strength and open up blood vessels.
• Anti-arrhythmics: If your pet has an irregular heartbeat, these medications help stabilise the heart’s electrical rhythm.

Specialised Diets and Supplements

A heart-healthy diet typically involves restricting sodium intake, as salt causes fluid retention, which places extra strain on the heart. Your veterinarian may also recommend supplements such as omega-3, taurine or L-carnitine. These nutrients support heart muscle health and reduce inflammation, helping to maintain energy levels and muscle mass.

Weight Management Guide and Gentle Exercise

Maintaining a healthy weight can support pets with heart disease by reducing strain on the heart. Gentle, controlled activity, such as short walks, may still be appropriate, depending on your pet’s condition.

However, overexertion should be avoided. It is important to follow your vet’s guidance on the type and intensity of exercise suitable for your pet.

Regular Monitoring and Check-ups

Heart disease is often progressive, meaning it can change over time. Regular veterinary visits allow for adjustments to medication and care plans.

Standard check-ups often involve diagnostic imaging to assess the heart’s structure and function. These include:

• Pet Ultrasound (Echocardiogram): This provides a real-time view of the heart, allowing vets to see how the valves are working and how the heart is pumping.
• Animal CT Scan: This test offers detailed, cross-sectional images of the heart and surrounding blood vessels. It is typically performed for complex cases or to check for concurrent issues in the lungs.

Surgical or Interventional Procedures

For certain heart conditions, medical management alone may not be enough. In these instances, surgical or minimally invasive interventional procedures are recommended.

One such advancement is the transcatheter edge-to-edge repair or TEER procedure. This is often used to treat dogs with severe mitral valve disease. It involves repairing the leaky valve without the need for open-heart surgery, significantly reducing recovery time and risk compared to traditional surgical methods.

Other procedures may include pacemaker implantation for irregular heart rhythms or balloon valvuloplasty to open narrowed valves.

What to Expect When Managing Your Pet’s Heart Disease

In most cases, heart disease is a chronic condition that requires ongoing management. Once medication or a specialised diet is started, it is usually continued long-term to help stabilise the condition and prevent symptoms from worsening.

Your pet’s treatment plan may change over time. As the disease progresses or as your pet ages, your veterinarian may adjust medications, dosages or monitoring frequency based on regular check-ups and diagnostic imaging.

FAQs About Heart Disease and Treatments for Pets

Is heart disease more common in certain breeds?

Yes, some breeds are more predisposed to heart conditions. For example, small dog breeds are more prone to mitral valve disease, while larger breeds may be at higher risk for cardiomyopathy.

Can my pet still exercise with heart disease?

In many cases, light and controlled exercise is still beneficial. However, the type and intensity of activity should always be guided by your veterinarian to avoid overexertion.

Is heart disease painful for pets?

Heart disease itself is not always painful, but it can cause discomfort due to symptoms like breathing difficulty or fatigue. Proper treatment helps improve comfort and quality of life.

Are there side effects from heart medications?

Some pets may experience mild side effects such as changes in appetite, increased urination, or lethargy. If you notice anything unusual, inform your veterinarian so adjustments can be made.

How soon will I see improvement after starting treatment?

Some pets show improvement within days, especially with medications that reduce fluid build-up. However, full stabilisation may take longer depending on the condition.
