عنوان مقاله [English]
Ischemic nephropathy can cause end stage renal disease in uremic patients. Renal artery stenosis caused by atherosclerosis is a progressive disease which maybe presented by kidney dysfunction, renal failure and acute pulmonary edema. In this study we wanted to findout the prevalence of renal artery stenosis in non diabetic patients with CAD and its relation with cardiovascular risk factors for finding the necessity of concurrency of renal and coronary angiography.
Materials and Methods
In this descriptive study in 2009-2010 in Imam Reza Hospital , 204 non diabetic patients who had coronary stenosis with inclusion criteria :1- stenosis of more than one vessel or its equivalent(more than 50 percent ) 2-undertreatment hypertension and increased intra-arterial pressure more than 140/90mmhg3- serum creatinin over 1.5 mg/dl underwent nonselective renal angiography during coronary angiography, data analyzed with SPSS software and K2 test, independent sample t test and logistic regression with p value less than 0.05.
Among multiple variables that had meaningful relation with RAS only increased diastolic intra -arterial pressure, number of involved coronary artery and undertreatment hypertension could predict renal artery stenosis.
In these 3 groups of patients such as: patients with more than one vessel stenosis (more than 50%), increased diastolic intra-arterial pressure and undertreatment hypertension, Concurrency of non selective renal artery angiography without non invasive test for assessment of renal artery stenosis during coronary artery angiography is recommended.
