Cardiac asthma is less common and refers to wheezing associated with heart failure.
It is a condition brought by severe reflexive blocking and can be edema of lungs.
Cardiac asthma is a type of breathing caused by sudden blockage of the pulmonary circulation.
Earlier, people mistook this disease as pulmonary edema or fluid in the lungs but later it became clear that cardiac asthma can occur without fluid in the lungs.
Cardiac asthma and pulmonary edema are symptoms of coming heart failure. It usually occurs in older people who have wheezing and shortness of breathe that are due to heart failure.
Cardiac asthma is a life threatening condition and you should seek medical advice if you experience any symptoms. This disease is caused due to the major fault of the heart and poses life threatening condition.
Fault in heart occurs when left part of the heart has a disproportion between its work load and work capacity suddenly, which causes additional stress to the heart. This inconsistency can lead to cardiac asthma.
Therefore fluid in the lungs is built up due to the reduced pumping effectiveness of the heart. Fluid build up causes narrowing of air passages and leads to wheezing and other symptoms.
Symptoms to distinguish cardiac asthma from others:
The main symptom of cardiac asthma is shortness of breath with or without wheezing, increased breathing, increased blood pressure, heart rate and feeling of uneasiness.
Cardiac asthma also causes you to wake up breathless a few hours after sleeping and you have to sit up right to breathe properly again.
When you lie down too long, fluid accumulates in the lungs and can lead to shortness of breath. Symptoms usually occur with exercise or at night before going to bed.
You can also see swollen ankles which are worsened with this disease. With these symptoms, you can distinguish this disease from other diseases and proper treatment can be given.
Treatment for cardiac asthma:
Treatment requires correct diagnosis, which includes differentiation between patients who wheeze only due to acute heart failure and those who wheeze from other disorders, such as asthma chronic obstructive pulmonary disease, pneumonia or acute respiratory syndrome.
Treatment concentrates on improving the pump function of the heart along with medications. If cardiac asthma is caused by a heart valve that is not working properly or a hole between the heart chambers, surgery or other procedures are suggested.
The treatment should focus on controlling night coughs, edema control, control of inflow load and the amount of residual blood in the left ventricle.
Treatment includes using diuretics to free the lungs of excess fluid and medications to help the heart muscles pump more effectively. Once the heart failure is controlled, the wheezing will gradually stop.
If you are suffering from cardiac asthma, you respond well to a combination of bronchodilators, supplementary oxygen and treatment of heart failure. Corticosteroids are prescribed depending on clinical circumstances and patient’s response to initial therapy.
