Heart Disease

Pet hearts are very similar to human hearts; they both have four main valves: a mitral valve, tricuspid valve, pulmonic valve, and aortic valve. The mitral valve, located between the heart’s left atrium and left ventricle is a pet’s most fragile valve and is usually the first to fail. In dogs, this failure occurs slowly and causes the pet to exhibit tell-tale symptoms that could trigger a pet-owner to realize something is wrong. However, heart disease in cats progresses much more rapidly and involves failure of the entire heart, which makes a pet owner’s detection of it much less likely.

At the onset of heart disease, a pet’s circulatory system starts to fail. With that failure, the kidneys, liver, and other vital internal organs are flooded with stationary blood and cannot function properly. The organs no longer get the essential amount of oxygen they need and slowly start to die. Heart disease is a very serious medical condition that must be addressed promptly. If you notice any of the following symptoms, please contact our office at your earliest convenience.

Symptoms of heart disease in pets: 

  • Bloated stomach. 
  • Coughing. 
  • Difficulty breathing. 
  • Lethargy. 
  • Rapid breathing. 
  • Reduced appetite. 
  • Restlessness. 
  • Weight loss.

Diagnosing a pet with heart disease

If a pet patient is suspected of having heart disease, the veterinarian will first listen to their heartbeat with a stethoscope. If a heart murmur can be heard, it signals the vet that one or more valves are not functioning correctly. The veterinarian will then perform an X-ray, checking for an enlarged heart. Additional testing may include an EKG or echocardiograph.

How is heart disease treated?

If heart disease is a pet’s official diagnosis, the treatment and prognosis varies based on pet species, breed, and the underlying causal condition. The veterinarian will formulate a treatment plan that focuses on getting the heart to pump efficiently to help your pet live comfortably. There are numerous medications that can help a pet when heart disease is caught early enough.

If you have any questions about heart disease or think your pet is demonstrating possible symptoms, please contact our office.

We took our 5 month old puppy in to get neutered today and had a great experience. They educate you on expenses without making you feel guilty if you decide against extra options. We were able to pick him up 5 hours after dropping him off which was also amazing. Would highly recommend to anyone looking for a vet.

Dr. Genova has been my 4 legged daughter's doctor for her whole life (10 years). He is very personable, informative and kind. I seriously cannot say enough positive things about him.. Why else would I trust him to take care of my baby girl?

The rest of the staff is also very kind. Most of them have changed throughout the years but one thing that hasn't is that you can immediately tell how much they all love animals.

This is definitely one of this places that I wish I could give more than 5 stars to.

We had our first experience at Village at Main Veterinary Hospital today and I couldn't wait to write a review because of how pleased I was with the entire staff and environment. I arrived way early for my appointment but they took me anyway since it was open with no problem at all. As soon as we walked in the door my puppy and I were greeted with smiles and even staff that didn't run the counter came out and greeted and loved on my puppy as well which really put her at ease. Every staff member acknowledged our presence at some point. We were taken back to an exam room and we saw Dr. Tran who was warm and loving toward my puppy, she really took her time and you could easily see that she loves what she does. Dr. Tran covered all of my questions I had planned to ask as well as asked if I had any others. I would highly recommend this clinic to anybody who has had a bad experience at another clinic because it will totally make up for it as it did in our case. Thank you so much again for making us feel right at home and loving what you guys do, I will continue to drive 30 minutes just to have my pooch continue to see you guys :)
