Ventricular septal defect (VSD)

Ventricular septal defect (VSD) is one of the more common congenital heart defects in cats. It is sometimes referred to as a 'hole in the heart'. The condition is often discovered in apparently healthy cats by a vet during a routine examination (such as before vaccination). What is a ventricular septal defect? Ventricular septal defect [...]

Investigating heart disease

It is important that your vet can recognise the early stages of heart failure (and therefore when to begin therapy, if necessary). Investigations of animals with heart disease are important to identify early signs of failure and to establish the appropriate timing and type of therapy. Heart disease and heart failure are not the same [...]

High blood pressure (hypertension)

Hypertension (high blood pressure) has long been known to be a problem in people and is being increasingly recognised in pets. Hypertension is very common in older people and is often associated with smoking, or with stressful living. In animals, hypertension is almost always caused by an underlying disease. What is blood pressure? When the [...]

Heart rhythm disturbance (atrial fibrillation)

There are many different heart problems that can affect cats. Some of these affect the rhythm of the heart beat and one such condition is atrial fibrillation. This is most commonly seen in association with severe heart disease. Atrial fibrillation does not cause any specific signs so it is unlikely that you will identify this [...]

Heart disease in your cat

Heart disease is increasingly common in cats, probably because their average life expectancy has increased due to improved veterinary care. Some heart defects may be present from birth (congenital heart defects) but only show symptoms as the cat gets older. Other diseases develop later in life as a result of the effects of ageing or [...]

Feline aortic thromboembolism

Cats may be struck 'out of the blue' by a blood clot resulting in dramatic signs (sudden onset of lameness and pain) and potentially devastating damage. The back legs and the right front leg are most often affected and may be paralysed. This is an emergency - if you suspect that your cat has suffered [...]

Congenital heart diseases

Bringing a new kitten into the family is an exciting time and should a time of great joy. It can be particularly distressing to find that your new arrival has a problem. It is important that you get your new kitten checked over by your vet so that any obvious problems can be identified before [...]

Cardiomyopathy

Cardiomyopathy is a disease affecting the heart muscle. There are two main forms of the disease - hypertrophic cardiomyopathy (HCM) and dilated cardiomyopathy (DCM). HCM commonly affects middle-aged cats and is more common in male cats than females. Cardiomyopathy is commonly associated with signs of heart failure and abnormal heart rhythms. How does the heart [...]
