Patients who have clinical symptoms of boredom in the heart spontaneously should consider some cardiogenic factors, such as coronary atherosclerotic heart disease, unstable angina or myocarditis, pericarditis, heart valve disease, infective endocarditis, hypertrophic obstructive cardiomyopathy, or even hypertensive cardiomyopathy. All of these diseases can cause clinical symptoms of boredom in the precordial region, usually due to ischemic stenosis of the coronary arteries. For example, patients with chronic bronchitis, chronic obstructive pulmonary emphysema, or chronic pulmonary heart disease may also experience boredom in the precordial region due to insufficient blood supply or lack of oxygen, accompanied by dyspnea and other symptoms. For some systemic diseases, such as endocrine metabolic diseases, including thyroid dysfunction, anemia, or patients with significant infections, may also lead to symptoms and manifestations of precordial boredom.
