Secondly, up to now, the specific cause of syndrome X is not very clear. It can only be in a hypothetical situation. It is generally believed that the endothelium-dependent coronary artery dilation is impaired, the sensitivity to sympathetic nerve stimulation is increased and the exercise-mediated coronary artery contraction is caused by the reduction of no production.

Finally, main symptoms: the main clinical manifestation of syndrome X is paroxysmal chest pain, which can be manifested as typical exertional angina pectoris and atypical chest pain, which can be manifested as stable angina pectoris, unstable angina pectoris and persistent resting chest pain. The duration of chest pain can be as long as 1-2 hours. The threshold of physical activity induced by a considerable number of patients is not constant, and they can wake up in the early morning.
