Murdoch's
HCM
This is Murdoch. Murdoch was brought to see our vet, Laurie, as an emergency due to his laboured breathing and lethargy.

Murdoch was seen by our vet, Dr Laurie, as an emergency due to his laboured breathing and lethargy. Laurie performed a thorough examination and discovered that his respiratory rate had increased. When he listened to his chest, his heart had a ‘gallop rhythm’ - an abnormal sound that can indicate heart disease. Murdoch was admitted for oxygen therapy and further investigation of his heart. He underwent an echocardiogram performed by Dr Kyle, as well as a CT scan.
​After investigation, we diagnosed Murdoch with Feline Hypertrophic Cardiomyopathy (HCM) - a condition where the muscular walls of a cat’s heart thicken. HCM is common in cats and is thought to affect around a third of cats over 9 years old. This thickening reduces the heart’s efficiency, making it harder to pump blood effectively. If left untreated, HCM can lead to complications such as congestive heart failure or an increased risk of blood clots.
We also discovered that Murdoch’s left atrium was enlarged, which indicates that his heart is under significant strain. His CT scan revealed fluid congestion in his lungs, confirming that his breathing difficulties were due to heart disease rather than another underlying condition. ​
​
Murdoch’s treatment plan has been carefully tailored to manage his HCM and associated congestive heart failure. He is receiving: Medication to reduce the risk of blood clots - a serious concern in HCM. Diuretics to help reduce fluid retention, easing the strain on his heart and lungs. Medications to support his heart function, improving its ability to pump blood effectively.
The goal of these treatments is to manage Murdoch’s condition, relieve his symptoms, and improve his overall quality of life. We’ll continue to monitor his progress closely, adjusting his treatment plan as needed to ensure he remains as comfortable and happy as possible.
A Message for Pet Owners
If your cat shows signs of laboured breathing, lethargy, or an increased respiratory rate, contact your vet as soon as possible. Early intervention can make a huge difference in managing heart conditions like HCM.
We’re optimistic that, with the right care, Murdoch will continue to lead a fulfilling life despite his heart condition. His journey is a reminder of how proactive veterinary care can help pets live longer, happier lives - even with complex conditions like HCM.
