Diabetes and intracerebral hemorrhage: baseline characteristics and mortality.

BACKGROUND AND PURPOSE: Acknowledging the conflicting evidence for diabetes as a predictor of short- and long-term mortality following an intracerebral hemorrhage (ICH), we compared baseline characteristics and 30-day and long-term mortality between patients with and without diabetes after an ICH, paying special attention to differences between type 1 (T1D) and type 2 (T2D) diabetes. METHODS: Patients with a first-ever ICH were followed for a median of 2.3 years. Adjusting for demographics, comorbidities and documented ICH characteristics increasing mortality after ICH, logistic regression analysis assessed factors associated with case fatality and 1-year survival among the 30-day survivors. Diabetes was compared with patients without diabetes in separate models as (i) any diabetes and (ii) T1D or T2D. RESULTS: Of our 969 patients, 813 (83.9%) had no diabetes, 41 (4.2%) had T1D and 115 (11.9%) had T2D. Compared with patients without diabetes, those with diabetes were younger, more often men and more frequently had hypertension, coronary heart disease and chronic kidney disease, with similar ICH characteristics. Patients with T1D were younger, more often had chronic kidney disease and brainstem ICH, and less often had atrial fibrillation and lobar ICH, than did patients with T2D. Diabetes had no impact on case fatality. Any diabetes (odds ratio, 2.57; 1.19-5.52), T1D (odds ratio, 7.04; 1.14-43.48) and T2D (odds ratio, 2.32; 1.04-5.17) were independently associated with 1-year mortality. CONCLUSIONS: Patients with ICH with diabetes exhibited a distinct pattern of comorbidities and disease characteristics with specific differences between T1D and T2D. Despite their younger age, T1D seems to carry a substantially higher likelihood of long-term mortality after an ICH than does T2D.

Diabetes mellitus and ischemic stroke in the young: clinical features and long-term prognosis.

OBJECTIVE: To compare risk factors, stroke characteristics, and long-term prognosis between nondiabetic young ischemic stroke patients and similar patients having either type 1 diabetes mellitus (T1D) or type 2 diabetes mellitus (T2D) to provide information for patient management, counseling, and future research in these patient groups. METHODS: Our database comprised 1,008 consecutive patients aged 15 to 49 with first-ever ischemic stroke from 1994 to 2007. Primary outcome measures were 1) nonfatal or fatal recurrent ischemic stroke and 2) composite vascular endpoint (myocardial infarction, any stroke, revascularization, or vascular death). RESULTS: Compared with nondiabetic stroke patients (n = 904), patients with T1D (44) or T2D (60) were more likely to have hypertension and stroke attributable to small-vessel disease (SVD). In addition, when compared with nondiabetic patients, those with T1D more frequently had coronary heart disease and peripheral arterial disease (PAD) and those with T2D more often had obesity, PAD, history of TIA, and stroke attributable to large-artery atherosclerosis, and T2D patients were also more likely to be older and male than were the nondiabetic patients. Mean follow-up in survivors was 9.0 (±3.8) years. Cumulative recurrent ischemic stroke rate at 10 years was 40.9% for T1D (14 events), 29.7% for T2D (15), and 12.0% for nondiabetic patients (94). Corresponding rates for the composite vascular endpoint were 65.1% for T1D (25), 46.9% for T2D (28), and 19.3% for nondiabetic patients (153). CONCLUSIONS: Our findings suggest that ischemic stroke patients with T1D or T2D exhibit a distinct risk-factor and etiologic profile and a worse vascular prognosis than do nondiabetic patients.
