- BACKGROUND AND PURPOSE: We examined the impact of hyperglycemia on ischemic and hemorrhagic stroke incidence comparing criteria based on fasting plasma glucose (FPG) and 2-hour plasma glucose (2-hour PG). METHODS: Data from 9 European cohorts comprising 18 360 individuals between 25 to 90 years of age were collaboratively analyzed. The maximum length of follow-up varied between 4.9 to 36.8 years. Hazards ratios (95% confidence intervals) for stroke incidence were estimated using Cox-proportional hazards model adjusting for known risk factors. RESULTS: In individuals without a prior history of diabetes, the multivariate-adjusted hazards ratio for ischemic stroke corresponding to 1 SD increase in FPG was 1.12 (1.02 to 1.22) and in 2-hour PG 1.14 (1.05 to 1.24). Adding 2-hour PG to the model with FPG significantly improved the prediction of the model for the incidence of ischemic stroke (chi(2)=4.72, P=0.03), whereas FPG did not improve the 2-hour PG model prediction (chi(2)=0.25, P=0.62). A significantly increased hazard ratio was also observed for previously diagnosed diabetes (2.26 [1.51 to 3.38]) and for screen-detected diabetes defined by FPG (1.48 [1.08 to 2.02]) and 2-hour PG (1.60 [1.18 to 2.16]). None of the criteria predicted hemorrhagic stroke. CONCLUSIONS: Diabetes defined by either of the criteria predicted the future risk of ischemic stroke but not the hemorrhagic stroke. The prediction is stronger for elevated 2-hour PG than for FPG levels.

- OBJECTIVE: We investigated stroke mortality in individuals in different categories of glycemia and compared hazard ratios (HRs) corresponding to a 1-SD increase in 2-h plasma glucose and fasting plasma glucose (FPG) criteria. RESEARCH DESIGN AND METHODS: We examined data from 2-h 75-g oral glucose tolerance tests taken from 13 European cohorts comprising 11,844 (55%) men and 9,862 (45%) women who were followed up for a median of 10.5 years. A multivariate adjusted Cox proportional hazards model was used to estimate HRs for stroke mortality. RESULTS: In men and women without a prior history of diabetes, multivariate adjusted HRs for stroke mortality corresponding to a 1-SD increase in FPG were 1.02 (95% CI 0.83-1.25) and 1.52 (1.22-1.88) and those in 2-h plasma glucose 1.21 (1.06-1.38) and 1.31 (1.06-1.61), respectively. Addition of 2-h plasma glucose to the model with FPG significantly improved prediction of stroke mortality in men (chi2 = 10.12; P = 0.001) but not in women (chi2 = 0.01; P = 0.94), whereas addition of FPG to 2-h plasma glucose improved stroke mortality in women (chi2 = 4.08; P = 0.04) but not in men (chi2 = 3.29; P = 0.07). CONCLUSIONS: Diabetes defined by either FPG or 2-h plasma glucose increases the risk of stroke mortality. In individuals without a history of diabetes, elevated 2-h postchallenge glucose is a better predictor than elevated fasting glucose in men, whereas the latter is better than the former in women.

- OBJECTIVE To study mortality in relation to fasting plasma glucose (FPG) and 2-h plasma glucose levels within the normoglycemic range. RESEARCH DESIGN AND METHODS Data from 19 European cohorts comprising 12,566 men and 10,874 women who had FPG <6.1 mmol/l and 2-h plasma glucose <7.8 mmol/l at baseline examination were analyzed. Multivariate-adjusted hazard ratios (HRs) and 95% CIs for deaths from cardiovascular disease (CVD), non-CVD, and all causes were estimated for individuals whose 2-h plasma glucose > FPG (group II) compared with those whose 2-h plasma glucose ≤ FPG (group I). RESULTS A total of 827 (246) CVD and 611 (351) non-CVD and 1,438 (597) all-cause deaths occurred in men (women). Group II was older and had higher BMI, blood pressure, and fasting insulin than group I. The multivariate-adjusted HRs (95% CIs) for CVD, non-CVD, and all-cause mortality were 1.22 (1.05–1.41), 1.09 (0.92–1.29), and 1.16 (1.04–1.30) in men and 1.40 (1.03–1.89), 0.99 (0.79–1.25), and 1.13 (0.94–1.35) in women, respectively, for group II as compared with group I. HRs were 1.25 (1.05–1.50), 1.09 (0.89–1.34), and 1.18 (1.03–1.35) in men and 1.60 (1.03–2.48), 1.05 (0.78–1.42), and 1.18 (0.93–1.51) in women, respectively, after additional adjustment for fasting insulin in a subgroup of individuals. CONCLUSIONS In individuals with both FPG and 2-h plasma glucose within the normoglycemic range, high 2-h plasma glucose was associated with insulin resistance and increased CVD mortality.
