Hypertrophic cardiomyopathy in dogs - Symptoms and treatment

See Dogs files

Hypertrophic cardiomyopathy is a rare heart disease in dogs. It occurs when the muscular walls of the heart thicken and become stiff. As a consequence, blood circulation is diminished, as the heart cannot pump enough blood during systole and it does not receive enough blood during diastole. This cardiomyopathy often leads to congestive heart failure..

Diagnosis of hypertrophic cardiomyopathy in dogs

The diagnosis of canine hypertrophic cardiomyopathy is difficult because there are often no symptoms and because when they exist they are very similar to those of other heart diseases. The initial examinations are auscultation and physical examination. EKGs, X-rays, or echocardiograms may then be done, as determined by the veterinarian.

Radiographs may show the presence of pulmonary edema and ventricular enlargement in some cases, but in many cases they do not provide useful information. Similarly, electrocardiograms are helpful in detecting arrhythmias, but not all dogs with hypertrophic cardiomyopathies have arrhythmias..

The only reliable test to diagnose this disease is echocardiography, or ultrasound of the heart. Unfortunately it is not available in all veterinary centers, so many times the diagnosis is made by ruling out other similar conditions.

Treatment of hypertrophic cardiomyopathy in dogs

Treatment for dogs with no symptoms consists of restrict exercise and keep a low sodium diet. Generally these dogs do not need further treatment, although it is necessary to do them periodic vet check-ups to control the disease.

Dogs that already have symptoms are in a more advanced stage of the disease and, in addition to the aforementioned care, may require different medications for your treatment. Diuretics are generally used to reduce fluid build-up, medications to regulate heart contractions in dogs with arrhythmias, and vasodilators. The drugs to be used, as well as the doses, depend on each case and should only be prescribed by the veterinarian.

The prognosis is good for dogs with no symptoms. However, the prognosis for symptomatic dogs will depend on how advanced the disease is. For the latter, the prognosis is often unfavorable.
