Fasting Insulin in Essential Hypertension

Abstract

Background: An association between essential hypertension and defective insulin secretion has been identified.

Objective: To estimate fasting serum insulin level in adult male with essential hypertension to observe its relationship to hypertension.

Methods: This cross sectional study was conducted in the Department of Physiology, Dhaka Medical College, Dhaka from July 2012 to June 2013. A total number of one hundred fifty male subjects were selected with age ranging from 25 to 45 years. Seventy five male essential hypertensive were enrolled from Out- patient Department of Medicine, Dhaka Medical College Hospital, Dhaka. Age matched seventy five apparently healthy males were studied as control. Fasting serum insulin level was measured by ELISA method and fasting blood glucose by glucose oxidase method. For statistical analyses, unpaired Students t and Pearsons correlation coefficient (r) tests were performed.

Results: Fasting serum insulin level was significantly (P<0.001) higher in essential hypertensive male patients than normotensive subjects. Fasting serum insulin level shows significant positive correlation with systolic blood pressure in hypertensive patients.

Conclusion: This study reveals that essential hypertension has positive and significant relationship with fasting serum insulin level.
