These results suggest that nonalcoholic hepatic steatosis is closely correlated with a subtle, chronic activation of the HPA axis in obese, otherwise healthy, individuals.

Background/Objective: Previous studies conducted both in the general and diabetic population have shown that pulse pressure (PP) can predict mortality from cardiovascular diseases. The aim of the present study was to investigate the relationship between PP and specific cardiovascular mortality, i.e. from cerebrovascular and ischemic heart diseases, in a well-characterized cohort of type 2 diabetic patients. Methods: A cohort of 1,128 known type 2 diabetic patients 56 to 74 years of age with at least 2 blood pressure measurements for each year between 1984–1986 was followed-up for ten years to assess specific causes of death. The analyses were carried out by using the mean and the coefficient of variation (CV) of PP. Results: By the end of the 10-year follow-up period, 375 patients (178 male, 197 female) had died (33%). The mean PP resulted as an independent predictor of all causes and cardiovascular mortality. Remarkably, the mean PP, but not the CV of PP, was highly predictive of mortality from cerebrovascular diseases. The risk of cerebrovascular mortality rose by 86% with a 10 mm Hg increase in mean PP. PP turned out to be the most important predictor of cerebrovascular mortality among various pressure indexes (mean, systolic and diastolic pressure). Conclusion: The mean pulse pressure, but not the coefficient of variation is a strong predictor of cardiovascular mortality, mainly from cerebrovascular diseases, in type 2 diabetic patients.
