Coronary artery spasm is usually prone to recurrence. Coronary artery spasm refers to a cardiac event caused by abnormal contraction of the coronary arteries caused by certain factors, resulting in narrowing or occlusion of the coronary vessels, referred to as coronary artery spasm. It is most commonly seen in congenital developmental defects or atherosclerotic stenosis of the coronary arteries, and is most often triggered by cold weather or emotional excitement. Generally speaking, after rest and treatment, the symptoms of coronary artery spasm have been relieved, if the patient is subjected to cold stimulation, or suffers from large emotional fluctuations, the coronary artery spasm will recur. The condition of coronary artery spasm can be mild or severe, in mild cases, there may be no obvious symptoms, in severe cases, there will be chest tightness, dyspnea, or even anterior heart colic and arrhythmia, or even myocardial infarction. Coronary artery spasm, if chest pain, can be manifested as the upper and middle sternum pressure, suffocation, often radiating to the left upper arm over the left upper arm medial, can be accompanied by a sense of imminent death. Chest pain for more than 30 minutes is considered to be myocardial infarction. Coronary artery spasm should be treated with calcium antagonists such as nifedipine and verapamil under doctor’s supervision, and myocardial infarction requires urgent surgical treatment. In case of heart discomfort, it is recommended to consult a doctor and follow the doctor’s instructions for examination and treatment to avoid serious consequences.
