Sažetak
The aim of our study was to assess cerebral vasoreactivity (CVR) in type 2 diabetes mellitus (DM2) and factors which may influence on it. According to previous studies, evaluating CVR in DM2 on the similar way, the results were dubious. For the evaluation CVR we used breath holding index (BHI) and transcranial Doppler ultrasound (TCD) in 50 patients with DM2 and 50 sex- and age-matched healthy controls. We observed epidemiologic and clinic data, other vascular risk factors and laboratory parameters. We found statistically significant difference in BHI between patients with DM2 (BHI=0.69±0.31) and age- and sex- matched healthy controls (BHI=1.33±0.28) (p<0.05). Because of a significant correlation between BHI and age (p<0.001) in healthy controls we made an adjustment of BHI for age before further analyses (BHIadj). In DM2 group we found a significant correlation between BHIadj and age (p=0.0004), fasting glycemia (p= 0.04), and albuminuria (p=0.04) (creatinine clearance in multivariate analysis (p=0.007)). Our study has shown that CVR is impaired in DM2 patients and that it’s severity was associated with age, fasting glycemia and renal function. Functional TCD is a very good screening method for detection and monitoring of cerebral microangiopathic changes in DM2 patients.
