No datum is so far available on the relation between age and the acute glucose response to stress in women with ST-elevation myocardial infarction (STEMI) treated with percutaneous coronary intervention (PCI). We evaluated the age-related differences in the acute glucose response in 373 STEMI women submitted to PCI. The oldest women, when compared to the other age subgroups, showed the higher admission and peak glycemia (P0.001 and P0.001, respectively) in the lack of differences in insulin, C-peptide, hemoglobin-glycated values and discharge glycemia values. At logistic regression analysis, the following variables were independent predictors of in-Intensive Cardiac Care Unit mortality: age (1-year step) [odds ratio 1.09, 96% confidence interval (CI) 1.04-1.15, PU0.001], admission glycemia (1 g/l step) (odds ratio 2.05, 96% CI 1.35-3.12, P0.001). At Cox regression analysis the following variables were associated with 1-year mortality (when adjusted for discharge glycemia): age (1-year step) (hazard ratio 1.13, 95% CI 1.04-1.22, PU0.005), estimated glomerular filtration rate (1 g/l step) (hazard ratio 0.93, 95% CI 0.90-0.96, P0.001). Age affects the acute glucose response to myocardial injury since older women showed the higher admission glucose values and the poorer in-hospital glucose control, in the lack of differences of insulin-resistance incidence. Glucose values were independent predictors of in-hospital mortality, but were not related to long-term survival.
