Abstract

Background: Atrial fibrillation (AF) is a common arrhythmia in the non-cardiac intensive care unit (ICU). However, data concerning AF incidence and predictors in such populations are scarce and controversial. The study aimed to investigate the contributing factors of new-onset AF in elderly patients within the medical intensive care setting.

Methods: Patients admitted to ICU during a 6-month period were prospectively studied. Patients admitted for short period postoperative monitoring and patients with chronic or paroxysmal AF were excluded. The conditions involved as AF risk factors or "triggers" from demographic data, history, and echocardiography were recorded. Acute Physiology and Chronic Health Evaluation II score was calculated. Electrolytes including some trace elements (zinc, copper, and magnesium) were analyzed.

Results: The study included 142 patients (49% females). Mean age was 69.5 ± 7.3 years. AF was observed in 12%. Diagnosis of pneumonia (P < 0.001), low copper (P < 0.0001) and low zinc levels (P < 0.0001) was significantly associated with the occurrence of AF. By multivariate analysis, they remained statistically significant (odds ratio, 7.0; 95% confidence interval, 2.0 - 24.6; P < 0.01).

Conclusions: A significant fraction of ICU elderly patients manifests AF. The relevant factors contributing to AF incidence in the elderly are pneumonia and low zinc and low copper.

老年重症监护病房房颤的触发因素:一项观察性研究
背景:心房颤动(AF)是一种常见于非心脏重症监护病房(ICU)的心律失常。然而,这些人群中有关房颤发病率和预测因素的数据很少且存在争议。本研究旨在探讨重症监护下老年患者新发房颤的影响因素。方法:对ICU住院6个月的患者进行前瞻性研究。术后短期监测住院患者和慢性或阵发性房颤患者被排除在外。从人口统计数据、病史和超声心动图中记录房颤危险因素或“触发因素”。计算急性生理和慢性健康评估II评分。电解质中含有微量元素(锌、铜、镁)。结果:纳入142例患者(49%为女性)。平均年龄69.5±7.3岁。房颤发生率为12%。肺炎(P < 0.001)、低铜(P < 0.0001)和低锌(P < 0.0001)的诊断与房颤的发生显著相关。通过多因素分析,它们仍然具有统计学意义(优势比7.0;95%置信区间为2.0 - 24.6;P < 0.01)。结论:ICU老年患者中有相当一部分出现房颤,肺炎和低锌低铜是导致老年人房颤发生的相关因素。
