Heart Murmurs in Pets: What Pet Owners Should Know

Learning that your pet has a heart murmur can be alarming, but at Volunteer Veterinary Hospital, we’re here to help you understand what it means and what steps you can take to support your pet’s heart health. You can make informed decisions to keep your pet happy and healthy with the proper knowledge and care.

What Is a Heart Murmur in Pets?

A heart murmur in pets occurs when there’s an unusual sound—often a swishing or whooshing noise—in the heartbeat. This sound typically results from turbulent blood flow within the heart, which can have various causes and levels of severity. Heart murmurs aren’t necessarily life-threatening, but understanding what they indicate about your pet’s heart health is crucial.

Signs of a Heart Murmur in Pets: What To Watch For

Heart murmurs in pets aren’t always easy to detect without a vet exam, but certain symptoms might signal an issue. If you notice any of these signs in your pet, it’s wise to consult with your veterinarian to rule out or address potential heart health concerns:

• Coughing: Persistent or frequent coughing can sometimes indicate a heart issue.
• Lethargy: Pets with heart murmurs may feel more tired than usual and lack energy.
• Shortness of breath: Difficulty breathing, especially after exercise, can be a red flag.
• Decreased appetite: Pets with heart conditions may lose interest in food.
• Fainting or collapse: Though rare, a severe heart issue can sometimes cause fainting.

If your pet shows any of these signs, don’t wait to bring them in for a checkup. Detecting the signs of heart murmurs early can help your veterinarian guide you on the best course of action for your pet’s care.

Diagnosing a Heart Murmur in Pets

During a routine veterinary exam, your veterinarian will listen to your pet’s heart using a stethoscope. If a murmur is detected, your vet may classify it based on its intensity, location, and when it occurs in the heartbeat cycle. Some standard methods used to diagnose a heart murmur include:

• Auscultation: This is the initial step where the vet listens to your pet’s heart to detect any unusual sounds.
• Echocardiogram (Heart Ultrasound): This imaging tool allows the vet to see your pet’s heart in detail, providing insight into the heart’s structure and function.
• Chest X-rays: X-rays help assess the size and shape of the heart and check for any signs of heart disease.
• Electrocardiogram (ECG): This test measures the heart’s electrical activity, helping detect abnormalities in rhythm or function.

These diagnostic tools provide valuable information, helping your veterinarian determine the cause of the murmur and assess your pet’s overall heart health.

Heart Murmur Treatment for Pets

If your pet is diagnosed with a heart murmur, treatment depends on the murmur’s cause and severity. Here are some common approaches to managing heart murmurs in pets:

• Medications: Some pets may benefit from drugs that support heart function and help manage symptoms.
• Dietary adjustments: A heart-healthy diet can sometimes alleviate the strain on the heart.
• Exercise restrictions: Pets with certain heart conditions may need reduced exercise to avoid overexertion.
• Regular checkups: Routine vet visits are essential to monitor your pet’s heart health and adjust their treatment plan if needed.

With the right treatment plan, many pets with heart murmurs can enjoy a high quality of life. Our goal is to help you navigate these options and provide the best care for your pet’s unique needs.

Managing Your Pet’s Heart Health: A Preventive Approach

Keeping your pet’s heart healthy involves routine care and preventive measures. Here are a few steps you can take to support your pet’s heart health:

• Schedule annual exams: Routine checkups allow for early detection of heart murmurs or other issues, giving your pet the best chance at a healthy heart.
• Watch their weight: Obesity can strain the heart, so maintaining a healthy weight is crucial.
• Provide heart-friendly nutrition: Talk to your vet about foods that support pet heart health.
• Encourage regular, moderate exercise: Exercise helps maintain a strong heart but should suit your pet’s needs.

Following these steps can help promote your pet’s overall well-being and support their heart health.
