If the patient has pericardial effusion, it is still necessary to maintain a light diet, eat small meals frequently, and especially avoid spicy and irritating foods.

Meanwhile, patients should pay attention to regular re-examinations of cardiac echocardiography and electrocardiograms, as the most effective and direct method for diagnosing pericardial effusion is puncture and fluid extraction for examination. For minor amounts of pericardial effusion, it is recommended that patients first observe and use medication, which can also help alleviate symptoms.

During this period, it is important to monitor changes in the patient's blood pressure and heart rate. If blood pressure rises or heart rate increases rapidly, it can exacerbate pericardial effusion. However, it is still crucial to actively use medication for early intervention, which can also help alleviate symptoms, and actively prevent upper respiratory infections.
