RESUMEN
The aim of the present investigation was to explore probable association of renal artery stenosis [RAS] with coronary artery disease [CAD] and the prevalence of renal artery stenosis [RAS] in patients with CAD. This study comprised 165 consecutive patients with CAD, including 52.7% males and 47.2% females with respective mean ages of 60.3 +/- 8.9 and 59.5 +/- 10.1. The patients underwent simultaneous coronary and renal angiographies, and the lumen reduction of 50% or more was considered as significant stenosis. Indeed, stenosis of more than 70% of the arterial lumen was regarded as severe. According to our findings, the prevalence of renal artery stenosis in our hypertensive and normotensive patients were 46.2% and 19.5% respectively [p=0.002]. Renal artery angiography revealed that 64 [38.8%] of the patients had simultaneous renal artery stenosis. RAS is more common in females than males [p=0.031]. Multivariate analysis revealed that among all examined factors, hypertension and serum creatinine were associated with RAS. There was no correlations found between gensini score and RAS [p=0.63]. We found a relatively high prevalence of RAS including 46.2% in hypertensive and 19.5% in normotensive patients in our patients with CAD
