This data are in correlation with previous studies IRAS (The Insulin Resistance Atherosclerosis Study) has shown that diabetes and glucose intolerance are independent risk factors connected with increase in intima–media thickness (IMT). SANDS trial (The Stop Atherosclerosis in Native Diabetics Study) have shown that reduction in other cerebrovascular risk factors (hypertension, hyperlipoproteinemia) can slower progression of IMT thickening in diabetic patients [16] and [17]. Previous studies as well as our results suggest that mechanical arterial properties (changes in BHI, AS as functional parameters) are affected first while hemodynamic remains

preserved (mean velocities were unchanged due to cerebral autoregulation ABT-263 in vivo mechanisms which are preserved in healthy individuals). Our results suggesting that there is a good correlation of BHI as functional parameter which reflect

functional state of the intracerebral blood vessels with arterial stiffness as functional parameter for extracranial blood vessels (CCA in our case) in population with diabetes mellitus [10], [15], [16] and [17]. Different pathophysiological www.selleckchem.com/products/BKM-120.html mechanisms during the lifetime cause vessel wall aging and subclinical endothelial dysfunction which is the first stage of the atherosclerosis, subtle change of vessel wall before appearance of either vascular remodeling Hydroxychloroquine cell line (diameter increase), intima–media thickening or plaque formation. This state is irreversible and it is early marker of atherosclerosis as well as systolic pressure increase and pulse pressure increase. Increased arterial stiffness and decrease in BHI values are normal in advanced age, but in younger individuals this changes are first signs of subclinical atherosclerosis, such individuals should be screened for cerebrovascular risk factors and followed up. In our case we have shown that glucose control is of great importance in diabetic patients in order to prevent vascular aging [3], [7], [11] and [15]. We have shown

that diabetic patients are at increased risk for cerebrovascular disease, but further studies should be performed in order to evaluate impact of changes in AS and BHI on other clinical manifestations (cognitive decline, every day activities, etc.) in diabetic patients [18] and [19]. “
“Some present studies show that OSAS is associated with a high risk of cardiovascular and cerebrovascular diseases, because of the high frequency of the risk factors for their appearance [12], [13] and [16]. Epidemiological data say that patients with OSAS often are overweight and have arterial hypertension, they usually smoke and are involved in alcohol abuse [7]. Apneic episodes can induce cardiovascular, hemodynamic and hemorrhagic changes, which are potential promoters for stroke incidence in patients with RF for CVD [4] and [9].
