Microalbuminuria is Associated With the Severity of Coronary Artery Disease Independently of Other Cardiovascular Risk Factors

Abstract

The potential early predictive value of microalbuminuria (MA) in the estimation of atherosclerosis and the relation between the degree of urinary albumin excretion and the extent of coronary artery disease (CAD) were investigated. Patients (n = 159) with stable angina pectoris and angiographically significant stenosis in at least 1 of the major coronary arteries were included. Microalbuminuria was measured by immunoturbidimetry. The extent of coronary artery stenosis was graded using the Gensini score. The Gensini score was significantly greater in patients who had MA. Also, the Gensini increased by 0.15 units with 1 unit increase in MA. In the groups who had diabetes mellitus and hypertension, there was no correlation between MA and Gensini score. The results of the present study suggest that MA is associated with the severity of CAD independent of other cardiovascular risk factors.
