Abstract

Atherosclerosis has a common systemic pathogenesis and simultaneously affects multiple vascular beds. There is two fold increase in coronary artery disease (CAD) mortality with concomitant renal artery disease and survival correlates inversely with the severity of renal artery Stenosis (RAS).

The aim of this study was to estimate the prevalence of significant renal artery stenosis in different age groups undergoing coronary interventions.

Subjects under going coronary angiography for Severe CAD were simultaneously screened for RAS by renal angiography and those with more than 70% stenosis were included in the study. Case records were reviewed for cardio metabolic risk factors(CRF) like hypertension, diabetes, smoking and dyslipidemia. Serum creatinine levels, left ventricular ejection fraction and the number of coronary arteries affected was also recorded. Cardio metabolic Risk factor prevalence rates in RAS positive and negative subjects were compared for predicting association between RAS and CRFs.

RAS prevalence rates progressively increased with advancing age(25 to 44 years 16.67%, 45 to 64 years 23.19% and above 65 years 45.23% p=0.00005). Neither cardio metabolic risk factors nor the number of affected coronary vessels were predictive of RAS.

Renal artery stenosis is common in subjects under going coronary interventions and prevalence rates significantly increase with advancing age None of the risk factors were predictive of RAS except age.
