Cardiovascular disease is the leading cause of mortality in the world. There are several risk factors for cardiovascular disease, such hypertension, dyslipidemia, obesity, diabetes mellitus and cigarette smoking. However, these classic risk factors do not entirely explain for future cardiovascular disease. As a result, many newer risk factors such as estimated glomerular filtration rate (eGFR), microalbuminuria, C-reactive protein (CRP), homocysteine have been evaluated as potential predictive factors. Microalbuminuria is gaining recognition as simple marker of atherogenic risk. Positive albuminuria is considered not only marker of renal damage but also signify systemic vascular damage since. In this study we want to evaluate the association between albuminuria and coronary atherosclerosis using angiography in cases with type 2diabetes mellitus by estimating urinary albumin excretion.
