If a patient has chest congestion after a meal, consider that it may be due to insufficient blood supply to the heart muscle induced by a full meal, causing the patient to have angina pectoris symptoms. For such patients, they should pay attention to eating less and more meals on weekdays and eat some light and easily digestible food. In addition, it is recommended to further clarify the presence of coronary artery disease by performing electrocardiogram, chest X-ray and cardiac ultrasound, and if necessary, coronary CT or even coronary angiography. In some patients, if there is chest congestion after meals, it is not excluded that the patient has gastrointestinal dysfunction or a certain degree of gastric ulcer, which makes it relatively easy to have postprandial pain, and for such patients, it is recommended that they can take oral omeprazole and perform gastroscopy if necessary.
