The impact of meteorological conditions on the occurrence of various cardiovascular events has been reported. The aim of this work was to study the correlations between weather conditions and the occurrence of type A acute aortic dissections (AADs). Between 1997 and 2007, all the medical records of patients who underwent surgery for type A AADs in Toulouse University Hospital (France) were reviewed. The clinical data were confronted with the meteorological data provided by the French national meteorological office (MétéoFrance) over the same period. Two hundred and six patients with spontaneous type A AADs underwent surgery during this period. The incidence of aortic dissection was higher in winter time than in summer (P=0.018). The days with aortic dissections were colder than those without aortic dissections (P=0.017). Statistical analysis highlighted a decrease of atmospheric temperature during the three days preceding the upset of the symptoms (P=0.0009). This work demonstrates a correlation between spontaneous type A AADs and low atmospheric temperature.
气象条件对各类心血管事件发生的影响已有报道。本研究的目的是探讨天气状况与A型急性主动脉夹层（AAD）发生之间的相关性。1997年至2007年期间，对法国图卢兹大学医院接受A型AAD手术患者的所有病历进行了回顾。将临床数据与同期法国国家气象局（MétéoFrance）提供的气象数据进行对比。在此期间，206例自发性A型AAD患者接受了手术。主动脉夹层的发病率在冬季高于夏季（P = 0.018）。发生主动脉夹层的日子比未发生主动脉夹层的日子更冷（P = 0.017）。统计分析显示，症状发作前三天大气温度下降（P = 0.0009）。这项研究表明自发性A型AAD与低气温之间存在相关性。
