Heart failure in clinical practice can be divided into left heart failure, right heart failure, and total heart failure. The symptoms of left heart failure primarily manifest as pulmonary congestion, including varying degrees of dyspnea, cough, coughing up pink frothy sputum, palpitations, fatigue, etc. As for right heart failure, it mainly shows as gastrointestinal congestion, with symptoms such as nausea, vomiting, loss of appetite, etc. Once heart failure symptoms appear, the patient must seek medical attention promptly, actively treat the primary disease, correct the symptoms and signs of heart failure, and then avoid excessive physical activity, infections, and other triggers that could exacerbate heart failure.
