Patients with diabetes mellitus were almost twice as likely to have a recurrent stroke ( hazard ratio [ HR ] , 1.8 ; 95 % confidence interval [ CI ] , 1.4-2 .3 ) , recurrent ischemic stroke ( HR , 1.8 ; 95 % CI , 1.4-2 .4 ) , disabling/fatal stroke ( HR , 1.8 ; 95 % CI , 1.2-2 .9 ) , myocardial infarction ( HR , 1.7 ; 95 % CI , 1.0-2 .8 ) , and death ( HR , 2.1 95 % CI , 1.6-2 .8 ) compared with patients without diabetes mellitus .
