Can autonomic nervous system dysfunction cause myocardial ischemia?

In general, autonomic nervous system dysfunction may lead to myocardial ischemia. It is recommended to seek medical attention and receive active treatment under the guidance of a physician. The specific analysis is as follows:

The autonomic nervous system consists of two major components: the sympathetic and parasympathetic nervous systems. When parasympathetic function is reduced or sympathetic activity is excessive, it can cause constriction of visceral and cutaneous blood vessels, elevated blood pressure, and rapid breathing. These changes increase the cardiac afterload, resulting in varying degrees of inadequate blood supply to the coronary arteries, leading to coronary ischemia and spasm, and subsequently causing symptoms of myocardial ischemia and hypoxia.

If myocardial ischemia is caused by autonomic nervous system dysfunction, medications that support nerve health may be taken as directed by a physician. Commonly used drugs include mecobalamin tablets, oryzanol tablets, and vitamin B complex tablets, which help alleviate symptoms.
