At this time, if the patient’s symptoms are frequent and the pain is aggravated, it is recommended that the patient should improve the coronary CTA or coronary angiography, to clarify the degree of stenosis of the heart blood vessels, and perform cardiac stent implantation if necessary, to avoid the occurrence of acute myocardial infarction and other serious complications.
