Brief Summary:
This study clarified the influence of myocardial bridge on coronary hemodynamics by clarifying FFR and d-FFR to guide clinical intervention and treatment.
Detailed Description:
Myocardial bridge is a congenital anatomical abnormality, which is generally considered to be a benign change, but individual can cause angina, myocardial infarction and even sudden death. Previously, it was believed that the degree of myocardial ischemia induced by myocardial bridge was related to factors such as the location, length, and systolic stenosis of the myocardial bridge shown by coronary angiography.However, in recent years, more and more evidence has suggested that there is a high degree of mismatch between anatomical stenosis and its function.Studies have shown that FFR and d-FFR can accurately evaluate the functional significance of stenotic lesions.This study intends to enroll patients who underwent coronary angiography due to chest pain and confirmed the left anterior descending artery (LAD) simple myocardial bridge systolic stenosis ≥30%, and the pressure guide wire was used to measure the FFR and d-FFR of the myocardial bridge lesion under static and dobutamine stress.Analyze the relationship between these functional parameters and the anatomical morphological characteristics of the myocardial bridge and other possible clinical influencing factors, and explore the influence of the morphological characteristics of the myocardial bridge on myocardial hemodynamics，so as to clarify the degree of myocardial bridge shown by angiography may induce obvious myocardial ischemia, which requires clinical intensive intervention.
