Baseline serum CK levels after admission were measured. The associations between CK and clinical outcomes (stroke recurrence, death, and disability, defined as modified Rankin scale score 3\u20136 or 2\u20136) were analyzed. Patients with elevated CK levels had higher risks of recurrent stroke (hazard ratio [HR], 1.53; 95% CI, 1.21\u20131.93), death (HR, 1.68; 95% CI, 1.10\u20132.58), and disability (modified Rankin scale score, 3\u20136; odds ratio, 1.57; 95% CI, 1.29\u20131.90) at 3\u00a0months after adjusting confounding factors. Similar results were found at 1\u00a0year. The effects of CK on death and disability were more significant in male patients than female patients (\n              <jats:italic>P<\/jats:italic>\n              value for interaction &lt;0.05). Elevated CK\u2010MB levels were not associated with clinical outcomes in this study.\n            <\/jats:p>\n          <\/jats:sec>\n          <jats:sec xml:lang=\"en\">\n            <jats:title>Conclusions<\/jats:title>\n            <jats:p xml:lang=\"en\">Elevated serum CK after ischemic stroke or transient ischemic attack is associated with higher risks of recurrent stroke, death, and disability at 3\u00a0months and 1\u00a0year. Serum CK may act as a useful predictor for recurrent stroke and poor functional outcomes in patients with acute ischemic stroke or transient ischemic attack.
