【摘要】 目的 研究急性主動脈夾層時間分布規律。 方法 回顧性研究我院2000年1月-2010年12月所有急性主動脈夾層患者的時間資料，分析其月份、季節、周以及時刻分布特點。 結果 急性主動脈夾層月份分布高峰點為1月4日，高峰段為9月21日～次年4月19日（Plt;0.05）；季節分布以冬春季較多（Plt;0.05）；周分布無高峰點及高峰段（Pgt;0.05）；時刻分布高峰點為上午10點及下午4點。 結論 急性主動脈夾層具有明顯的時間分布規律，我們應該在該病的高峰時間更加重視其發生的可能，從而減少誤診，改善預后。【Abstract】 Objective To investigate the features of time distribution in the occurrence of acute aortic dissection (AAD). Methods We retrospectively analyzed all the databases of AAD in our hospital between January 1, 2000 and December 31, 2010, and studied the monthly, seasonal, weekly, and circadian distribution of the cases. Results In terms of monthly distribution, the occurrence of AAD peaked at January 4th with the high frequency in the period of September 21st to April 19th of the next year (Plt;0.05). According to the seasonal distribution, the occurrence of AAD peaked in winter and spring (Plt;0.05). There was no peak time in weekly distribution (Pgt;0.05). In accordance with circadian distribution, the occurrence of AAD peaked at 10 and 16 o’clock (Plt;0.05). Conclusion Because of the obvious rhythm of time distribution of AAD, We can pay more attention to the diagnosis of AAD especially in the peak time, thus reducing the mistakes in diagnosis and improving the prognosis.
