Studyofangiographicassociationofatheroscleroticrenalartery stenosiswithcoronaryarterydiseaseinBangladesh

This retrospective observational study aimed to see the angiographic association of atherosclerotic renal-artery stenosis (ARAS ) with coronary artery disease in Bangladesh. It was conducted in department of cardiology, University Cardiac Centre, Bangabandhu Sheikh Mujib Medical University, Dhaka from January2007 to January2008.A total of 250 patients with coronary artery involvement, on non-emergent coronary angiogram who underwent either selective or nonselective renalangiographywereenrolledinthisstudy.Among250patients,52(20.8%)patienthadsinglevesseldisease( SVD ),49 (19.6%)and149(59.6%)haddoublevesseldisease( DVD )andtriplevesseldisease( TVD )respectively.ARASwasdetect - ed in 37.2% or 93 patients. ARAStends to increase with age. In age group of 30-40,ARAS is 7.4% whereas in age group of51-60yearsitis41%.Theincidenceof ARASishighin50.25±9.98years;p=0.0001.33.3%malepatientswith CAD had ARAS whereas it was 44.3% in female patients with CAD . ARAS is more common in female 44.3%vs33.3%; p=0.02. ARAS prevalence increased with the number of stenosed coronary arteries (3.8% in 1-vessel, 26.5%in 2- vessel, 52.3%in 3-vessel CAD; p=.0001.). Hypertension and angiographically proven CAD were independent predictors of ARAS (p=0.0001). In conclusion, ARAS prevalence and severity increases with the number of arterial territories involved and CAD severity. Hypertension and 2-3-vessel- CAD were identified independent predictors of ARAS .
