Why Does A Leaky Heart Valve Cause A Cough?

Answer

Hi Sandra: Generally, a cough is caused by back pressure of blood from the Left Atrium into the pulmonary veins.

When a person has a leaky mitral valve, the pressure rises inside the left atrium. This pressure gets reflected back to the lungs and hence fluid there causes a person to cough. This can be with exercise.

Some cases of a cough reflect mild congestive heart failure. If a person lays flat they cough.

Also a cause can be caused by the medication called an ACE inhibitor.

So a number of ways that a cough can occur with a leaky valve.

I hope this helps.
