10 Warning Signs of A Heart Attack

Warning Sign #5: Persistent Cough
Coughs are such a common symptom that you are unlikely to think much of it at first. They are usually down to something quite harmless, but you should not be too complacent about them. If the cough does persist, or if it becomes too severe, then you should arrange to find out what is causing it.
In some cases, a persistent cough will be caused by a heart problem. Congestive heart failure causes blood to back up into the lungs due to the inability of the weakened heart to sufficiently circulate blood. A cough, which may or may not include mucus, may then be experienced due to this pulmonary edema.
