Association of Micro Albuminuria With Diastolic Function in Obese Normotensive No Diabetic Individuals

Background: recently, an association between impaired diastolic function and increased urinary albumin excretion has been hypothesized.objectives: we tried to assess the association between diastolic function and micro albuminuria in normotensive no diabetic obese individuals.patients and methods: this cross-sectional study was conducted on 186 consecutive obese normotensive no diabetic individuals who were older than 18 years and attended the outpatient health clinic at the tehran municipality in 2011. systolic and diastolic blood pressures were measured using a standard mercury sphygmomanometer. micro albuminuria was defined as abnormal urinary albumin to creatinine ratio (uacr) between 30 and 300 mg/g/d.results: an adverse significant linear correlations was found between the uacr measurement and diastolic function (r = -0.184 and p = 0.012); however, this correlation was insignificant for systolic function (r = 0.007 and p = 0.926). multivariable linear regression analysis showed that uacr index had a significant reverse correlation with diastolic function (standardized beta = -0.218 and p = 0.006).conclusions: our study obtained some evidences on the association of micro albuminuria with diastolic dysfunction in obese normotensive no diabetic individuals. nonetheless, more assessment is necessary for obtaining a causal relationship between micro albuminuria and diastolic dysfunction.
