急性缺氧对健康人三尖瓣返流的影响
Effect of acute hypoxia on tricuspid regurgitation
摘要
Abstract
Objective To explore the effect of acute hypoxia on tricuspid regurgitation .Methods 176 healthy young males were selected and their tricuspid regurgitation parameters in normoxia and after acute exposure to hypoxia ( oxygen concentrations 12%) were collected by color Doppler technology .The conditions of tricuspid regurgitation were compared between the two groups .Results Tricuspid regurgitation was significantly increased after the subjects were exposed to hypoxia.Tricuspid regurgitation rate (76% vs 48%), regurgitation pressure (25.65 mmHg vs 19.33 mmHg) and maxi-mum regurgitation velocity (251.38 cm/s vs 220.62 cm/s) were higher in the hypoxia group .However, there was no significant change in the regurgitation area .After two weeks of adaptation to hypoxia , the tricuspid regurgitation rate (50%vs 76%), regurgitation pressure (20.83 mmHg vs 25.65 mmHg) and maximum regurgitation velocity (225.69 cm/s vs 251.38 cm/s) significantly decreased and returned to the level before hypoxic exposure .Conclusion Acute hypoxic expo-sure can induce and aggravate tricuspid regurgitation ,and short-term adaptation to hypoxia can reverse the trend .关键词
