Heart failure causes fluid to flow from the lungs, causing them to fill with blood "causes the lungs to feel as if they're full of water.
The lungs get inflamed and cough to evacuate the water. This cough sounds 'wet' because of lung fluid buildup. The cough sounds like it contains water or sputum."
Sometimes, the lungs can't produce enough fluid, and the cough sounds more dry because of this. The medical term for this condition is heart asthma.
Heart failure can induce edema in the lungs and airways. This can produce asthma-like breathlessness, coughing, and wheezing.
According to the American Heart Association, a cough that produces crimson or pink mucus could be a sign of heart failure.
When your heart can't keep up with blood supply, it "backs up" in the pulmonary veins that carry blood from the lungs to the heart. Mucus can be white or foamy.
According to Verywell Health, paroxysmal nocturnal dyspnea (PND) may be present when the lungs are impacted by fluid accumulation and the resultant cough wakes you during the night.
PND is characterized by awakening from sleep with extreme shortness of breath, coughing, and the need to sit up, stand up, or open a window for air.
The most prevalent causes of a persistent cough are asthma and chronic obstructive pulmonary disease, two treatable illnesses that cause inflammation of the lungs.
If a cough persists despite treatment for these conditions, heart disease may be at blame.
Coughing may be caused by the same buildup of fluid that Medical News Today characterizes as "crackling, gurgling, or the sound of an impending explosion."
Consult your physician if you are experiencing this or any other symptoms of heart disease in order to have the issue evaluated and possibly treated.
