ABSTRACT
Objective To analyze the clinical and laboratory characteristics of the ischemic stroke in patients with non-valvular atrial fibrillation (AF), and to provide evidence for the prevention of ischemic stroke. Methods A total of 198 patients with ischemic stroke were chosen and divided into two groupswith AF (71 patients)/and without AF (127 patients) groups. Clinical data and biochemical markers were collected and compared in two groups. CHADS2 and CHA2DS2-VASc score systems were used to determine the risk levels in patients with AF. Finally, related risk factors of ischemic stroke with AF were determined and analyzed. Results The values of age, length of hospital stay, the hypertention history, heart rate and plasma homocysteine (Hcy) were significantly higher in the with-AF group than those in the without-AF group ( P <0.05). The levels of total cholesterol (TC), triglyceride (TG) and very low density lipoprotein cholesterol (VLDL-C) were sig?nificantly lower in the with-AF group than those of the without-AF group (P<0.05). CHA2DS2-VASc scores reached to the moderate-to-high risk level in the with-AF group. Multiple-factor logistic regression analysis showed that age and heart rate were the independent risk factors of the ischemic stroke in patients with non-valvular AF. ROC analysis indicated that age (AUC=0.761, cut-off point=72.50 years old) and heart rate (AUC=0.612, cut-off point=76.50 bit/min) had predictive and di?agnostic value for the ischemic stroke in patients with non-valvular AF. The age of these patients had the best sensitivity (70.4%) and specifity (71.1%), and the cut-off point of which was 72.50 years old. Conclusion The characteristics of isch?emic stroke in patients with non-valvular AF includes older age, faster heart rate, higher CHA2DS2-VASc scores and higher Hcy level.
