The authors hypothesized increased emergency department (ED) visits for heart failure (HF) during a 2-week Christmas holiday period similar to a recent study showing increased cardiac death rates. A retrospective analysis was performed from a database of 18 EDs in New Jersey and New York from January 1, 1996, to November 30, 2004, analyzing HF visits from December 1 to January 31. The authors compared the mean daily visits for the 2-week holiday period of December 25 to January 7, as well as December 26 to December 30 and January 2 to January 5, using the Student t test. A total of 4.7 million patients were studied, 65,646 with an ED diagnosis of HF and 11,525 during January and December. There was a 23% (95% confidence interval [CI], 14%-31%; P<.001) increase in daily visits for December 25 to January 7 and a 33% (95% CI, 16%-51%; P=.007) and 30% (95% CI, 22%-38%; P<.01) increase in the 4 days following Christmas and New Year's, respectively. The authors found a significant increase in daily HF visits in the 2-week holiday period and the 4 days following the holidays, even greater than that reported for sudden cardiac death.
作者们推测，在为期两周的圣诞节假期期间，因心力衰竭（HF）前往急诊科（ED）就诊的人数会增加，这与最近一项显示心脏死亡率上升的研究类似。对1996年1月1日至2004年11月30日期间新泽西州和纽约州18家急诊科的数据库进行了回顾性分析，分析了12月1日至1月31日期间因心力衰竭就诊的情况。作者使用学生t检验，比较了12月25日至1月7日这两周假期期间、12月26日至12月30日以及1月2日至1月5日的日均就诊人数。总共研究了470万名患者，其中65646人在急诊科被诊断为心力衰竭，11525人在1月和12月期间就诊。12月25日至1月7日的日均就诊人数增加了23%（95%置信区间[CI]，14%-31%；P<.001），圣诞节和新年后的4天里分别增加了33%（95%CI，16%-51%；P=.007）和30%（95%CI，22%-38%；P<.01）。作者发现，在为期两周的假期期间以及假期后的4天里，因心力衰竭的日均就诊人数显著增加，甚至高于突发性心脏死亡的报告人数。
