Clinical Evaluation of Vasomotor System Functionality in Type 2 Diabetic Patients

Background: autonomic neuropathy and vital organ dysfunctions are the known complications in type 2 diabetes mellitus (dm). genetic endowments involving individuals make subtle differences in physiological systems,particularly at the time of sickness. hence,the presented study was designed to evaluate the vasomotor system in healthy people and type 2 dm cases for determining any functionality differences between the mentioned groups. methods: sixty patients with type 2 diabetes (case group) and sixty healthy subjects (control group) matched for age and sex were enrolled in the study. then,the performance of vasomotor system was assessed using valsalva maneuver,cold pressor,sustained hand-grip and mental arithmetic tests and the differences were determined via statistical methods. results: according to our findings,abnormal response to valsalva maneuver was found in the case group (p=0.028) and the same response was seen about mental arithmetic evaluations. in the case of cold pressor and sustained hand-grip tests,remarkable differences were not found in both groups. important differences were also found among vasomotor dysfunction and the time of dm labeling. conclusion: this study showed a higher incidence of vasomotor dysfunction in dm patients. however,revision in cold pressor and sustained hand-grip tests definition as well as methodology was recommended.
