Just like humans, a cat’s heart is hollow, made of muscle, located in the center of the chest and has four chambers. The two upper chambers are called the atrium, which collects circulating blood, and the lower chambers are called the ventricles, which pumps blood from the heart.
3. Heart Attacks Are Very Rare in Cats
Cats frequently have heart disease, but heart attacks are extremely uncommon. Though most cats have other forms of heart disease, they can be deadly when they do occur.
8. Kittens Can Have Heart Murmurs
When your veterinarian listens to your cat’s heart, they will be able to detect an unusual sound called a heart murmur. This noise is typically caused by abnormal and turbulent blood flow in the heart. Humans can suffer heart murmurs, and so too can cats. Heart murmurs can occasionally occur in kittens, and by the time they are six months old, these innocent heart murmurs usually go away on their own. But there are other, possibly more dangerous reasons for heart murmurs, so it’s best to have them examined by a veterinarian.
POSSIBLE COMPLICATIONS OF HEART DISEASE IN CATS
Cats with heart disease may experience several additional complications in addition to congestive heart failure. It is common for a big blood clot to form inside the heart in hypertrophic cardiomyopathy. If pieces of this clot break free and enter the bloodstream, they may lodge in blood vessels and stop the flow of oxygen to nearby tissues.
Where the aorta splits to supply blood to the hindlimbs is a common site for the deposition of these clots. If this happens, the patient will become extremely painful and quickly lose the ability to use their hindlimbs. A small percentage of these patients may be able to regain circulation with intensive supportive care before permanent damage is done.
Because of the poor prognosis and high likelihood of surviving patients to experience another clot, euthanasia must be considered in these situations. Patients with HCM can also develop arrhythmias associated with the structural changes that occur within the heart. If recognized, these can usually be controlled with anti-arrhythmic medications for variable periods.
