Coughing
Persistent wheezing and coughing are common symptoms of respiratory issues, but they can also indicate the presence of heart failure. Due to the congestion in your lungs caused by the accumulation of blood, you might generate whistling noises when breathing. In addition, a cough with pinkish or white phlegm rather than yellow or green is relatively typical of heart failure, particularly when you also experience shortness of breath at the same time. The problem might get worse when you sleep during the night. [4]
