Seasonality in ischaemic coronary artery disease is well documented with a winter/summer variation the commonest pattern. The influence of seasonal variation on events in other vascular territories is less well documented. The incidence of ruptured abdominal aortic aneurysm and emergency lower-limb ischaemia was analysed on a monthly basis over a 5-year period. A total of 372 ruptured abdominal aortic aneurysms occurred with a peak incidence in spring and autumn; however, no seasonal pattern was seen in the rate of emergency admissions with lower-limb ischaemia (n = 606). The explanation for this seasonal pattern in ruptured aneurysms is unknown. The haemodynamic adjustments to changes in climate require further study.
缺血性冠状动脉疾病的季节性变化已有充分记录，常见模式为冬季/夏季变化。季节性变化对其他血管区域事件的影响记录较少。对5年内腹主动脉瘤破裂和下肢急性缺血事件的发生率进行了月度分析。共发生372例腹主动脉瘤破裂，发病率在春季和秋季达到峰值；然而，下肢缺血急诊入院率未见季节性模式（n = 606）。腹主动脉瘤破裂这种季节性模式的原因尚不清楚。气候改变时的血流动力学调整需要进一步研究。
