You have a sudden persistent cough
Don’t let frequent coughing fits fool you into thinking it’s just another nasty cold. If cough suppressants don’t do the trick, it could be one of the signs of heart trouble. “Sometimes when there is fluid in the lungs from congestive heart failure, one can have wheezing and a cough, which can mimic asthma or lung disease when it really is a cardiac problem,” says Dr. Michos.
Fluid starts to accumulate in your lungs when your heart isn’t pumping blood properly, which backs up your blood vessels and causes fluid to leak into unusual places like your lungs. An unhealthy heart could also be the culprit behind chronic obstructive pulmonary disease, an umbrella term for progressive lung diseases that make it hard for you to breathe.
