Cardiac asthma is wheezing, heart failure and in the true sense is not asthma. Clinically, it is a condition caused by severe reflexive blocking and or by pulmonary edema. It is asthma-type breathing caused by sudden blockage of the pulmonary circulation. The bronchial spasms in asthma, cardiovascular caused by back pressure from the left side of the heart to the lungs. Symptomatic asthma heart quite similar to lung asthma.
in patients with heart failure or heart valves that do not open properly experience shortness of breath not necessarily accompanied by wheezing, cough, increased speed and superficial breathing, increased blood pressure and heart rate and a feeling of uneasiness. Symptoms usually occur with exercise or at night after going to bed. Cardiac asthma is usually due to a major mechanical failure of the heart. Less pumping efficacy of the heart leads to a build up of fluid in the lungs. This accumulation of fluid causes the air way to narrow up and eventually cause wheezing and other related symptoms. It is a life-threatening condition and one must seek medical advice immediately on experiencing any symptoms.
key to successful asthma cardiac function is 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 and acute respiratory distress syndrome . Treatment is aimed at improving the pumping function of the heart along with medications.
Treatments mainly focus on controlling the night coughs, control of water, control of inflow load and the amount of residual blood in the left ventricle. Diuretics (water pills) free the lungs of excess fluid and other drugs, such as morph ines, nitrates help the heart muscle pump more. Breathing difficulties gradually stop when the heart has been well managed.
In some patients who suffer from asthma and heart failure simultaneously need to treat both conditions. The combination of bronchodilators, supplementary oxygen is generally effective in controlling asthma symptoms in addition to the treatment of heart failure in these patients. Corticosteroids are prescribed when a patient with acute cardiac asthma has not responded well to initial treatment. Corticosteroids usually take long hours to give maximum effect. If asthma caused by a heart valve that is not working properly or a hole between heart chambers, surgery or other procedures may be suggested.
