Application study of the CHA2 DS2-VASc score in the prognosis assessment of an initial cardioembolic stroke with atrial fi-brillation / 中国医师杂志

ABSTRACT

Objective To investigate prognostic value of the CHA 2 DS2-VASc score [ congestive heart failure , hypertension , age≥75y (doubled), diabetes mellitus, stroke (doubled)-vascular disease, age 65~74 and sex category (female)] in an initial car-dioembolic stroke with atrial fibrillation .Methods A total of 346 initial cardioembolic stroke patients with atrial fibrillation was en-rolled.The clinical feature, the National Institutes of Health Stroke Scale (NIHSS) score on admission, and clinical outcome [modi-fied Rankin Scale (mRS) score after 90 days] were obtained and evaluated retrospectively according to the CHA 2DS2-VASc score. Results The rate of female, smoking, hypertension, congestive heart failure, anticoagulation and the level of age, NIHSS score, and CHA2 DS2-VASc score were significantly different between two prognostic groups ( P <0.05 ) .A positive correlation was observed be-tween CHA2DS2-VASc score and NIHSS score on admission (ρ=0.324, P <0.01), CHA2DS2-VASc score and mRS score (ρ=0.228, P <0.01).Logistic regression analysis showed that age , smoking, anticoagulation, the CHA2DS2-VASc score, and the NIH-SS score on admission were related to clinical outcome independently .Conclusions The CHA2 DS2-VASc score may be useful for not only evaluation of stroke risk but also prediction of clinical outcomes after stroke .
