To analyze if previous diagnosis of diabetes influences stroke severity and in-hospital outcome in acute cerebral infarction (CI) patients.Observational study between 1998-2004 with inclusion of consecutive patients with CI. Risk factors, stroke subtype, severity on admission (Canadian Stroke Scale [CSS]), in-hospital complications, mortality, length of stay and stroke outcome (modified Rankin Scale [mRS]) in CI patients with and without previous diagnosis of diabetes were compared.A total of 2,213 consecutive acute stroke patients; 661 with previous history of diabetes (29,9%) were included. These patients were older, had more rate of hypertension, dyslipidemia, coronary arterial disease, peripheral vascular disease and previous stroke than non-diabetic patients. Atherotrombotic and lacunar infarction were more frequent in diabetic patients. They also had more in-hospital complications as urinary tract infection (4.7 % vs 2.6 %; p0.05), multiple organ dysfunction syndrome (3.3% vs 1.8%; p0.05), deteriorating stroke (6.1 % vs 3.4 %; p0.01), recurrent stroke (3.3% vs 1.7%; p0.05) and increase of infarction volume (2.6 % vs 1.1%; p0.05), with no differences in stroke severity at admission, mortality, length of in-hospital stay and stroke outcome. Previous history of diabetes was independently associated with in-hospital complications (OR: 1.377; CI 95%: 1.053-1.799).Previous diagnosis of diabetes is not associated by itself to higher stroke severity on admission although a greater risk of in-hospital complications is found.
