Abstract
BackgroundAlbuminuria is one of the abnormalities which occur in diabetics. Different studies have shown its relationship with cardiovascular diseases but few studies have been performed to show the relationship between albuminoria level and coronary artery disease (CAD) severity. This study was designed to asses the relationship between albuminuria and coronary artery disease severity. MethodsIn this cross-sectional study, the 164 Non-Insulin Dependent Diabetes Mellitus patients with angina pectoris who hospitalized for diagnostic or therapeutic angiography in Isfahan Chamran hospital were included. Urine Pr/Cr ratio has been calculated in all patients, using the first sample of morning urine. The standard angiography video has been assessed by three cardiologists through Seldinger method. CAD score has been given from 0 to 21 based on Extent method. The relationship between CAD severity and urine Pr/Cr ratio has been assessed with bivariate correlation methods and multivariate analysis. FindingsIn 164 patients (males = 80 & females = 84) morning urine protein mean was 22.77 ± 30.99 and morning urine creatinin mean was 0.07 ± 0.04. Urine Pr/Cr ratio was 760.94 ± 401.56 mg/g and its median was 181.02. The CAD score was equal to 13.34 ± 6.24. There was no correlation between urine Pr/Cr ratio and CAD severity (P = 0.778, r = 0.022). In multivariate analysis , increased urine Pr/Cr ratio led to increased CAD severity by control of the age, FBS, gender, Captopril use, history of HTN and hyperlipidemia variables (P = 0.021). ConclusionThe amount of albuminuria which measured based on morning urine sample Pr/Cr ratio may be an independent risk factor for severity of CAD and can predict it. These findings signify the importance of albuminuria diagnosis and treatment. Key words: Severity, Coronary artery disease, Albuminuria, Angiography.
