Abstract

Abstract:

Objective

To analyze the clinical features, risk factors and prognosis of patients with transient ischemic attacks (TIA) in posterior circulation, and provide the evidence for prevention of stroke.

Methods

We prospectively selected 88 posterior circulation TIA patients from October 2010 to December 2013, analyzed their clinical features, risk factors (hypertension, diabetes, hyperlipoidemia, coronary artery disease, atrial fibrillation and smoke).

Results

69.3% patients were older than 60 years. The most common feature of posterior circulation TIA patients were dizziness (44.3%) and the duration of symptoms was less than ten minutes (43.2%). The incidence of hypertension was highest (48.9%) among these risk factors. 20.5% patients had vertebrobasilar arterial stenosis≥50%. And 8% (7/88) patients suffered stroke in 7 days after TIA. The Logistic regression analysis of 6 risk factors (hypertension, diabetes, hyperlipoidemia, coronary artery disease, atrial fibrillation and smoke) showed that diabetes was the independent risk factor of the stroke after posterior circulation of TIA (OR=5.867, 95%CI: 1.186-29.014,P<0.05).

Conclusion

The clinical features of patients with transient ischemic attacks (TIA) in posterior circulation were complex. Hypertension was the most common risk factor and diabetes may affect more on stroke after TIA.
