title: Prevalence of renal artery stenosis in patients undergoing routine cardiac catheterization.
abstract: OBJECTIVE
  To determine the prevalence of renal artery stenosis (RAS) and associated risk factors in patients undergoing cardiac catheterization for suspected coronary artery disease.
  
  
  METHODS
  Three hundred and fifty-four consecutive patients (71 female) were studied at the Cardiology Unit of King Abdullah University Teaching Hospital, Irbid, Jordan, between May 2002 and May 2003. Left-sided cardiac catheterization and abdominal aortography were performed to screen for coronary and renal artery disease.
  
  
  RESULTS
  Of the 354 patients, 285 had coronary artery disease and 27 had RAS. Significant RAS was present in 11 patients. Patients with RAS were older (66 +/- 8 versus 59 +/- 10, mean +/- SD; p=0.004), had higher incidence of systolic hypertension (156 +/-14 versus 130 +/- 16 mm Hg; p=0.005), diabetes mellitus (72% versus 38%; p=0.004), smoker (85% versus 55; p=0.005), and had less than 2 coronary lesions.
  
  
  CONCLUSIONS
  The prevalence of significant and insignificant RAS is 3.1% and 4.5%. Diagnostic yield increase in elderly patient with less than 2 coronary lesions, elevated systolic pressure, smoking, diabetes mellitus, and electrocardiogram criteria of left ventricular hypertrophy.
