Cardiac asthma, although technically not a form of asthma, is a term used to describe asthma-type symptoms caused by heart failure. Like asthma, it can develop at any age and can exhibit many similar symptoms. Patients may wheeze due to a build-up of fluid in the lungs. In cases of cardiac asthma, the patient also exhibits additional symptoms that indicate heart failure such as heart and liver enlargement and fluid retention.
Treatment for cardiac asthma differs from normal asthma treatment in that diuretics are often administered to reduce the build-up of fluids.
