Background

Atrial fibrillation is an important risk factor for stroke but there are limited data on atrial fibrillation-related stroke from the Middle East.

Methods

We interrogated the Qatar Stroke Database to establish the occurrence, clinical features, and outcomes of atrial fibrillation-related stroke at Hamad General Hospital, the sole provider of acute stroke care in Qatar.

Results

A total of 4079 patients (81.4% male, mean age 55.4 ± 13.3 years) were enrolled in the stroke database between January 2014 and 21 October 2017. Atrial fibrillation was present in 260 (6.4%) patients, of whom 106 (2.6%) had newly diagnosed atrial fibrillation. The National Institute of Health Stroke Scale (NIHSS) was significantly higher (7.9 + 7.0 (median 6; IQR 11) vs. 5.9 + 6.4 (median 4; IQR 6), P < 0.001) in atrial fibrillation patients. The modified Rankin Score (mRS) (P < 0.001) and mortality at 90-day follow-up (P = 0.002) were significantly higher in atrial fibrillation compared to non-atrial fibrillation stroke patients.

Conclusion

We demonstrate a low rate of atrial fibrillation and stroke in Qatar, perhaps reflecting the relatively young age of these patients. Atrial fibrillation-related strokes had higher admission NIHSS, greater disability, and higher mortality at 90 days when compared to non-atrial fibrillation strokes.

卡塔尔房颤和中风的发生率，临床特征和结局

背景

心房颤动是中风的重要危险因素，但中东有关房颤相关中风的数据有限。

方法

我们询问了卡塔尔中风数据库，以建立哈马德综合医院（卡塔尔唯一的急性中风护理提供者）与房颤相关的中风的发生，临床特征和结局。

结果

在2014年1月至2017年10月21日之间，卒中数据库中共纳入4079名患者（男性81.4％，平均年龄55.4±13.3岁）。房颤出现在260名（6.4％）患者中，其中106名（2.6％）刚被诊断出房颤。美国国立卫生研究院卒中量表（NIHSS）在房颤患者中明显更高（7.9 + 7.0（中位数6; IQR 11）与5.9 + 6.4（中位数4; IQR 6），P <0.001）。与非心房颤动卒中患者相比，心房纤颤的改良兰金评分（mRS）（P <0.001）和90天随访时的死亡率（P = 0.002）显着更高。

结论

我们证明卡塔尔的房颤和中风发生率较低，这可能反映了这些患者的年龄相对较小。与非心房颤动卒中相比，与心房颤动相关的卒中在90天时的NIHSS住院率更高，残疾更大，死亡率更高。
