Abstract:
Objective To investigate the risk factors of cerebral microbleeds (CMBs) in patients with acute isch?emic stroke of large-artery atherosclerosis. Methods One hundred twelve patients with acute ischemic stroke of large-ar?tery atherosclerosis admitted from July 2013 to January 2014 in Nanjing First Hospital affiliated to Nanjing Medical Uni?versity were enrolled. According to the results of MRI magnetic sensitive weighted imaging, the patients were divided into CMBs group or non-CMBs group. The history, general clinical data, serum biochemical results and MRI in both groups were enrolled. All the data were analyzed by the univariate and multivariate analysis. Results The results of univariate analysis showed that there were significant differences in age (61.620±11.479 vs. 70.620±11.185), serum uric acid (UA) level (278.920±69.512 vs. 353.460±111.206), serum creatinine (Cr) level (71.360±19.797 vs. 90.450±44.989), serum ho?mocysteine (Hcy) level (12.587±2.664 vs. 21.715±10.437) between the two groups (P<0.05). There were significant differ?ences in constituent ratio of Fazekas' s grade of periventricular hyperintensities and deep white matter hyperintensities between the two groups (P<0.05). The results of multivariate analysis showed that age (OR=0.963, 95%CI:0.905~1.025, P<0.05) and serum Hcy level (OR=1.487, 95%CI:1.219~1.813, P<0.05) were the independent risk factors for CMBs in patients with acute ischemic stroke of large-artery atherosclerosis. Conclusions Age and serum Hcy level are the inde?pendent risk factors for CMBs in patients with acute ischemic stroke of large-artery atherosclerosis.
