How to Diagnose and Prevent Feline Hypertrophic Cardiomyopathy

1 How to Diagnose and Prevent Feline Hypertrophic Cardiomyopathy

1. How feline HCM is diagnosed

1) Auscultation: first, listen for a heart murmur and judge whether the beat and sound are abnormal. If you hear a gallop rhythm or arrhythmia, further testing is needed.

2) ECG: the best way to detect arrhythmia. By disease severity it may show as normal, or an R wave above 0.9 mV indicating left-ventricle load.

3) Echocardiography: the gold standard for diagnosing heart disease. It checks changes in ventricular structure and evaluates heart function.

4) X-ray: a chest X-ray cannot diagnose HCM, because early HCM does not change the heart’s outer outline, but it can show pulmonary edema, pleural effusion, or pulmonary artery enlargement.

5) Breath count: watch the cat’s resting respiratory rate. Normally a cat breathes fewer than 30 times per minute.

2. Preventing feline HCM

There is no good way yet to prevent feline HCM. The best approach is regular check-ups — let the vet listen or run an echocardiogram. Also, if the cat already has heart disease, kidney failure, or hyperthyroidism, tell the vet early, since these can cause secondary cardiomyopathy; early checks mean early control.

1) Feed a healthy, balanced diet. Owners who make homemade cat food should control sodium and add taurine. Limit salty foods like organ meat and seafood, and always keep nutrition balanced.

2) To avoid cardiomyopathy as much as possible, skip the very high-risk breeds when choosing a cat, and think it through first — these cats have a high chance of dying from the disease.

3) If the cat is already diagnosed with heart disease, give it a quiet enough environment and avoid stimulating exercise; play with it less.

If your cat has the misfortune of HCM, do not panic — take it to a proper hospital, return for regular check-ups, and follow the vet’s advice so it can stay with you longer.
