Asymptomatic Renal Artery Diseases In Ischaemic Heart Disease Patients With Normal Renal Functions Undergoing Coronary Angiography In A Tertiary Care Hospital

Abstract

Background and objectives ABSTRACT Atherosclerotic renal artery stenosis (RAS) and coronary artery disease (CAD) arise from the same multiple risk factors. This study was designed to determine the frequency of asymptomatic renal artery disease with normal renal functions in patients who had coronary artery disease. Methodology This one year cross-sectional study was done in the Department of Medicine, KLES Dr. Prabhakar Kore Hospital and Medical Research Centre, Belgaum from January 2014 to December 2014. Data was gathered from a total of 480 patients who underwent coronary angiography with normal renal functions were evaluated for the presence of asymptomatic renal artery disease with internal blockage of ≥70%. Results Majority of the patients were males (74.19%) and male to female ratio was 2.96:1. The most common age group was 41 to 60 years (50.21%) and the mean age was 57.59 ± 10.56 years. Most of the patients (49.15%) had single coronary artery disease. Involvement of renal artery was noted in 47.71% of the patients. Bilateral involvement was noted in 48.48% of the patients. The incidence of significant renal artery disease was noted as 8.33%. 25 off the 108 patients with triple vessel disease had significant renal artery disease (23.15%) (p<0.001). The most common risk factor was low HDL (79.17%). Renal artery disease with not associated with sex, age and traditional risk factors. IV Conclusion and interpretation The incidence of asymptomatic significant renal artery disease (≥ 70%) is high in patients suspected to have coronary artery disease (8.33%) and patients having triple vessel disease are at risk of developing renal artery disease
