Generally, coronary artery spasm cannot be detected by performing a coronary angiogram.
Coronary artery spasm is a transient constriction of the coronary arteries, causing partial or complete occlusion of the vessels. It can cause resting angina with transient ST-segment elevation on the ECG.
Coronary artery spasm is generally self-resolving and difficult to capture with conventional coronary angiography. The imaging procedure is complex and relatively long, and the coronary arteries may already be in remission during the examination, which is usually undetectable.
When coronary artery spasm occurs, calcium channel blockers (nifedipine) and nitrate drugs (nitroglycerin) can be taken orally to relieve the spasm and angina symptoms.
When coronary artery spasm occurs, it is recommended to seek medical treatment in time, and the drugs need to be regulated under the guidance of professional doctors.
