[Comparison of vascular risk factors profiles for transient ischemic attacks and ischemic stroke].

BACKGROUND AND OBJECTIVE

To determine vascular risk factor (VRF) profiles in transient ischemic attack (TIA) and ischemic stroke.

PATIENTS AND METHOD

We studied 239 patients with TIA and 1,473 ischemic stroke patients included in a prospective stroke registry over a 10-year period.

RESULTS

Main VRF were: hypertension, hyperlipidemia, diabetes mellitus and atrial fibrillation. In the multivariate analysis, prior ischemic stroke (OR=1.65; 95% CI, 1.07-2.56), atrial fibrillation (OR=1.60; 95% CI, 1.14-2.26) and current use of warfarin treatment (OR=0.34; 95% CI, 0.13-0.94) were the only independent risk factors associated with ischemic stroke.

CONCLUSIONS

Different potentially modifiable vascular risk factor profiles were identified in ischemic stroke versus TIA. This suggests that there are pathogenic differences between TIA and ischemic strokes.
