Why does cardiac cough occur?
It is known that with the help of cough the body(organism) tries to protect itself, and it happens by the stimulation of cough receptors located in the bronchi. During the cardiac cough, such stimulation causes the pulmonary edema. The swelling develops due to a disturbance in the work of the heart - because of blood clots in the lungs. After all, it is the heart that provides blood supply to the small blood vessels that supply the bronchial system.
