Abstract | BACKGROUND AND AIMS: Inconsistent findings have been reported regarding the association between elevated plasma homocysteine (Hcy) levels and the risk of different types of strokes. We conducted this meta-analysis to identify the association between homocysteine (Hcy) levels and different kinds of strokes or recurrences of strokes. METHODS AND RESULTS: PubMed and Embase databases were searched for relevant studies published prior to April 2013. Only prospective studies that compared elevated Hcy levels with the risk of different types of strokes were selected. Results were presented as the relative risk (RR) and the corresponding 95% confidence intervals (CI) comparing the highest Hcy category group with the lowest Hcy category group. Nine studies composed of 13,284 participants were included. The pooled RR of ischemic strokes when comparing the highest Hcy category group with the lowest Hcy category group was 1.69 (95% CI: 1.29-2.20) in a fixed-effect model. The pooled RR of hemorrhagic strokes and recurrent strokes when comparing the highest Hcy category group with the lowest Hcy category group in a fixed-effect model was 1.65 (95% CI: 0.61-4.45) and 1.76 (95% CI: 1.37-2.24), respectively.
