Effect of Duration of Diabetes patient on Valsalva Ratio

Abstract

Introduction: Autonomic neuropathy is a serious complication of diabetes mellitus which is least recognized & most frequent. Cardiac autonomic neuropathy is associated with not only fatal intra-operative liability but also morbidity in life style. . In this study we are going to evaluate diabetic autonomic neuropathy using Valsalva ratio. Objective: To observe & compare Valsalva ratio in diabetic cases & healthy controls. To evaluate the effect of duration of diabetes on Valsalva ratio. Material and method: After proper application of inclusion & exclusion criteria 100 subjects were chosen from Sir T. Hospital. 50 with diagnosed diabetes mellitus, and 50 age and sex matched healthy control. This 100 subjects were examined and Valsalva ratio assessment evaluation was done by instrument cardiac autonomic nervous system analyzer -304
Results: The mean of test group and control group were 2.25 and 3.63 respectively. This mean values decreases and percentage of subjects with autonomic dysfunction increases as duration of disease increases.
Conclusion: The parasympathetic system imbalance is more prevalent in diabetics & its condition worsens as the duration of disease increasing.
