- Abstract:
- AIMS: This study aimed to determine the prevalence of renal artery stenosis (RAS) and associated risk factors in patients undergoing cardiac catheterization for suspected coronary artery disease (CAD). METHODS: One hundred and seventy-seven consecutive patients (62 females) with a serum creatinine concentration <2.0mg.dl(-1) were studied. Abdominal aortography followed cardiac catheterization to screen for RAS. RESULTS: In 110 patients (62%) CAD and in 19 patients (11%) significant RAS (luminal narrowing of >or=50%) were detected, 12 of whom had high grade (>or=70%) RAS, and two subjects had significant RAS without CAD. Patients with RAS were older (67+/-8 vs 61+/-11 years, mean+/-SD;P =0.004), had higher systolic blood pressure (150+/-15 vs 138+/-20 mmHg;P =0.005), a lower glomerular filtration rate (GFR; 61+/-16 vs 80+/-22 ml.min(-1), P<0.001) and more often diabetes mellitus (69% vs 30%; P=0.004). In multivariate analysis a low GFR and the extent of CAD were independent predictors of RAS. The presence of >2 significant coronary lesions predicted RAS (sensitivity 0.84, specificity 0.77, positive predictive value 0.30, negative predictive value 0.98). CONCLUSION: Screening for RAS in patients with >2 diseased coronary segments has a high diagnostic yield, which is even greater in the presence of a reduced GFR, diabetes mellitus, and elevated systolic blood pressure.
