Abstract:
Objective:To provide references for the aeromedical qualification of flying personnel with myocardial bridges by retrospectively analysising the clinical characteristics and aeromedical qualification results.Methods:The clinical characteristics and aeromedical qualification of military flying personnel who underwent coronary angiography examinations and diagnosed as myocardial bridges in Air Force Medical Center from January of 2010 to January of 2020 were compared and analyzed.Results:A total of 84 segments of myocardial bridge diseases were detected in 79 flying personnel diagnosed as myocardial bridges located in the left coronary artery system, of which the middle segment of the left anterior descending artery accounted for 73.81% (62/84). A total of 77 single-segment myocardial bridges occurred in the anterior descending artery in 79 flying personnel diagnosed as myocardial bridges, of which 28 cases were combined with atherosclerotic lesions of the anterior descending artery. The areomedical qualification concluded that 49 cases were qualified for flight, 27 cases were temporarily disqualified, and 3 cases were disqualified. There were significant differences in treadmill exercise results and myocardial ischemia between the qualified and temporarily disqualified groups ( χ2 =7.902, 7.832, both P=0.005). Conclusions:Myocardial bridges in military flying personnel mainly occurs in the middle of the left anterior descending artery, which is easy to merge with proximal coronary atherosclerotic lesions, and the existing clinical evaluation indicators are not accurate enough, and the basis for areomedical qualification needs to be further improved.
