Paradoxical high augmentation index in females with diabetes mellitus.

The relationship between diabetes mellitus (DM) and augmentation index (AIx) remains unclear. We conducted an observational cross-sectional study. Subjects were patients who underwent coronary angiography. We examined the relationship between high AIx and several factors. The total number of diabetic patients was 144, and median AIx was 0.256. In diabetic patients, the significant relationship between female gender and high AIx (median cut-off value, >= 0.256) was found by the multivariate logistic analysis (adjusted odds ratio = 2.888; 95% confidence interval: 1.032-8.081). The significant relationship between female gender and high AIx was found in patients with DM.
