Exceptionally high sputum in heart failure is related to factors such as pulmonary edema and lung infection caused by heart failure. When heart failure occurs, there will be pulmonary edema, and the exudate in the lungs will increase significantly, and the patient may show a lot of sputum, mainly foamy sputum, and some patients may have pink foamy sputum. Heart failure is mostly triggered by acute lung infections, and heart failure may be accompanied by pneumonia, and lung infections can also lead to sputum symptoms. Patients with heart failure have to pay attention to the expectorant drugs, but the main treatment is to reduce the heart failure, but be careful to avoid excessive diuresis, otherwise it will lead to sputum thick and not easy to cough out, combined with lung infections should be given antibiotic treatment at the same time. Patients with heart failure should be treated regularly under the guidance of a physician, and anti-heart failure treatment should be given at the same time as anti-infective treatment if necessary.
