Heart disease, cardiomyopathy in cats

The heart of cats has four chambers: right and left atrium;as well as the right and left ventricles. The left ventricle is responsible for oxygen saturation from the lungs and its injection into the aortic valve. Hypertrophic cardiomyopathy( HCM) affects the left ventricle and its

ability to pump blood into the aorta. In the cardiomyocytes of the left ventricle muscle abnormally enlarged or thickened. In a cat, such as the Main Coon, there may be other heart disease, but they may not be related to HCM.

Some species have a genetic predisposition to this condition. In some cats in Maine Coon, a particularly large number of cases have been reported. Cardiomyopathy occurs in American Shorthair and in Persian cats, but the role of genetics in these cases is definitely not defined.

The most common cardiomyopathy occurs in cats aged 5 to 7 years, although the age range of registered cases is much wider and ranges from 3 months to 17 years. Most cases of registration in this case are males. Heart noises in old cats are usually caused by other diseases, hypertension and hyperthyroidism.

Signs and symptoms:

  • Lethargy
  • loss of appetite, anorexia
  • Difficulty breathing
  • weak pulse
  • Short, clicking sounds when breathing( crackling)
  • Inability to tolerate exercise
  • Heart murmurs
  • Sudden paralysis of hind limbs
  • discoloration pads paws blue tint thatindicates lack of oxygen
  • Heart failure

Causes of cardiomyopathy

The cause of cardiomyopathy in many cases remains unknown. However, it is known that genetic mutations and predispositions often lead to the development of the disease in some breeds of cats. Additional cardiac diseases, such as hypertension or hyperthyroidism, can further complicate cardiomyopathy in cats.


You should provide the full health history of your cat, until the onset of symptoms. The main methods for diagnosing cardiomyopathy in cats is the recording of ECG( electrocardiogram) and radiography of the heart. To test the animal for other diseases, he may need some other tests and tests. Hyperthyroidism is manifested in cardiomyopathy-like symptoms, such as lethargy, heartbeat and shortness of breath.

Treatment for

If you have a diagnosis of cardiomyopathy, your cat needs hospitalization for proper care, especially if it suffers from congestive heart failure, which often occurs during the illness. Your cat needs a calm environment to minimize possible stress, and if she has breathing problems, she may also need oxygen therapy.

There are several drugs that can be used to treat cardiomyopathy:

  • Cardiac pacemaker and
  • treatment for irregular heart beat Beta blockers help slow down heart rate rhythms
  • ACE inhibitors - used in cases of congestive heart failure
  • Aspirin - used to reducerisk of blood clots
  • Preparations for preventing blood clotting
  • Diuretics - for removing excess fluid from the body

Proilaktyka and control disease

cat should be put on a diet with restriction of sodium, especially in cases of congestive heart failure to maintain a stable pressure. To restore it, it is also necessary to provide a quiet and comfortable space in the house, away from sources of noise and other pets. Excessive stress can activate the nervous system and load the already overloaded left ventricle of the cat, which, in turn, can lead to heart failure.

During the recovery period, you should closely monitor your cat, tracking breathing problems, lethargy, low appetite, pain or paralysis of the limbs. You will also need to ensure that the animal is not exposed to acts that could lead to injury. After the course of the cat's treatment, it is necessary to undergo a repeated ultrasound examination of the heart to determine the progress and the need for further recovery.
