There is always a feeling of pressure in the forehead which may be related to coronary heart disease, myocardial ischemia, thymoma, and so on. 1. Coronary heart disease: also known as coronary atherosclerotic heart disease, refers to the accumulation of cholesterol and other substances in the arteries, which leads to the arterial lumen continues to narrow or occlusion, triggering coronary heart disease. When the patient suffers from coronary heart disease, the typical symptom of chest compression will appear, which makes the patient feel that there is always a sense of pressure in the chest. 2. Myocardial ischemia: it is a pathological state, which may be caused by coronary artery stenosis, coronary artery spasm and so on. Typical symptoms of myocardial ischemia are discomfort and pain in the anterior region of the heart during exercise, and the discomfort in the anterior region of the heart can be manifested as tightness and constriction, which may lead to a feeling of pressure in the chest. 3. Thymoma: it is a kind of tumor that often occurs in the anterior mediastinum, and patients are asymptomatic in the early stage of the disease. When the size of the tumor is increasing, it will exert pressure on the surrounding organs, thus making the patient feel that there is always a sense of pressure in the forehead. When patients feel pressure in the anterior thorax, they should consult a doctor in time to get a clear diagnosis and treatment from a professional doctor.
