There is no relationship between buzzing inside the head and myocardial ischemia. The causes of buzzing in the head include cervical spondylosis, trauma, mental and psychological factors, cerebrovascular abnormalities, etc., and myocardial ischemia is not necessarily related. 1. cervical spondylosis: due to cervical spondylosis compression of blood vessels in the craniocervical spine, which can lead to insufficient blood supply to the brain, thus causing head buzzing. 2. trauma: seen in patients who have had a history of cervical spondylosis. 2. trauma: seen in patients who have had craniocerebral trauma, and most of them are sequelae. 3. mental and psychological factors: for example, patients with anxiety, often stay up late, etc., may also be accompanied by symptoms of buzzing in the head. 4. Cerebrovascular anomalies: for example, congenital malformations of cerebrovascular development can affect the blood supply to the brain, which can lead to buzzing in the head. Myocardial ischemia is not a disease, but a pathological condition. It is mainly caused by insufficient blood supply to the coronary arteries and increased myocardial oxygen consumption. Common causes of myocardial ischemia include coronary artery disease, myocardial bridges, coronary artery spasm, and cardiac arrhythmias. The buzzing feeling in the head and myocardial ischemia is generally not related, the patient should go to the hospital in time to find out the cause of myocardial ischemia under the guidance of the doctor to cooperate with the treatment.
