Hypertension is a major public health problem all over the world. The incidence of hypertension is increasing year after year and the prevalence of hypertension is increasing day by day due to increased life expectancy and aging population and their sedentary lifestyle. Hypertension is known to cause microvascular changes and increased cardiovascular risk from it. Microalbuminuria possibly reflects a state of increased renal endothelial permeability and is an easily measured marker of rather diffuse endothelial dysfunction, low grade inflammation and vascular disease burden2. Microalbuminuria has been determined as an important prognostic indicator and has been reported to be associated with increased cardiovascular risk and progressive renal damage. Reliable data on the prevalence of microalbuminuria in the general population and its association with cardiovascular risk factors is limited. Till now, there is little data available regarding screening and early treatment of hypertensive patients with microalbuminuria, as in the case of microalbuminuric non diabetic subjects. With these perspective this cross sectional study of microalbuminuria in non-diabetic hypertensive patients was undertaken to study prevalence of microalbuminuria in Non Diabetic hypertensive patients. Objectives: To determine the prevalence of microalbuminuria in non-diabetic hypertensive patients and to correlate the presence of microalbuminuria with the patients of different clinical profiles. Materials and Methods: This was observational, cross sectional study of Patients diagnosed with hypertension either admitted in ward or attending OPD of Medical College and Tertiary Care Centre. Urine microalbumin creatinine ratio was used for estimation of microalbuminuria. Conclusion: It was proved that microalbuminuria prevalence was directly proportional to the duration of hypertension, the stage of hypertension. Prevalence of microalbuminria was low in ACE inhibitor and ARB treated hypertensive patients.
