Increased aortic stiffness in women with Type 1 diabetes mellitus is associated with diabetes duration and autonomic nerve function

Aims The increase in risk for cardiovascular complications in women is even greater than that in diabetic men. We found arterial to be increased in wo men, but not in men, with Type 1 diabetes IDM). The aims of the present stu dy were to evaluate whether the changes in arterial distensibility are infl uenced by diabetes duration and to evaluate any association between autonom ic neuropathy and decreased arterial distensibility. Methods Stiffness of the abdominal aorta was measured noninvasively using e cho-tracking sonography and parasympathetic function by heart rate variatio n during deep breathing (E/I ratio) in 40 women (mean age 33 years, range 2 0-61) and 38 men (mean age 36 years, range ZZ-SS) with Type 1 DM. Results There was a significant correlation between aortic stiffness and du ration of diabetes in women (r = 0.41, P = 0.008), but not in men (r = 0.15 , P = 0.35). There was also a significant correlation between aortic stiffn ess and the E/I ratio in women (r = -0.49, P = 0.002), but not in men (r = -0.14, P = 0.41). When adjusted for diabetes duration, the significant asso ciation between the E/I ratio and aortic stiffness remained in diabetic wom en (r = -0.14, P = 0.008) and was stronger than the association between dia betes duration and aortic stiffness. There were no significant correlations between aortic stiffness and triglycerides or total cholesterol, respectiv ely. diabetic stiffness mellitus changes Conclusions Increased aortic wall stiffness found in women with Type 1DM is related to diabetes duration. Further, in women with Type 1DM there is a c orrelation between increased aortic stiffness and parasympathetic dysfuncti on. This may be of importance for the increased susceptibility to cardiovas cular complications in diabetic women.
