Coronary heart disease patients with poor appetite are alerted to heart failure In general, patients with heart failure mainly show symptoms such as weakness, chest tightness and shortness of breath after activity, and in severe cases at rest, symptoms such as chest tightness, breath-holding and even coughing up pink frothy sputum can occur. A small number of patients may also suffer from insufficient blood supply to the gastrointestinal tract, slowed intestinal peristalsis and reduced secretion of digestive enzymes due to left ventricular insufficiency, which may cause symptoms such as abdominal distension, anorexia and weakness. In addition, when the right heart fails, there is stasis of blood in the gastrointestinal tract, which can also suppress appetite. Another condition is that when heart disease is severe, the body also releases inflammatory factors, which can also cause a decrease in appetite. Patients with severe coronary artery disease leading to heart failure are most likely to have a loss of appetite and may even lose weight rapidly due to poor appetite consumption. In some patients with atypical symptoms of inferior wall myocardial infarction, GI symptoms may be the only discomfort, and even misdiagnosis may be delayed by considering only gastroscopy and finding no abnormalities. If there is no gastric disease or other digestive tract diseases, and the appetite suddenly becomes poor, attention should be paid to timely treatment and examination at the hospital to exclude heart failure and other diseases. Especially for elderly people with hypertension, coronary heart disease and other cardiovascular diseases, it is especially important to take precautions.
