Toward a better understanding of temporal patterns of aneurysmal subarachnoid hemorrhage.

摘要

Lindgren et al. [1] have examined temporal patterns of aneu-rysmal subarachnoid hemorrhage (aSAH) in a consecutive series of 1,862 patients presenting to Kuopio University Hospital in Eastern Finland within 72 h of ictus between 1980 and 2007. They demonstrate that onset of aSAH occurred more often on Sundays and Mondays and least often on Saturdays. They attempted to analyze variables that may significantly and independently associate with the Sunday and Monday peaks using logistic regression; however, no variables were identified. Admission to Kuopio University Hospital pursuant to aSAH was most frequent on Monday and least frequent on Thursday and Saturday. Additionally, they found that amongst the 1,655 patients undergoing occlusive therapy for their ruptured aneurysm, the procedure was undertaken most frequently on Monday and least frequently on Saturday and Sunday.
