Renal Artery Stenosis and Its Risk Factors in Patients Undergoing Concomitant Cardiac and Renal Angiography

Aim: We sought to find patients requiring concomitant coronary and renal angiography for the reduction of renal insufficiency and cardiovascular events. Methods and Results: Prospectively, we recruited 881 patients (432 men, 449 women) who underwent simultaneous coronary and renal angiography with the inclusion criteria of presence of undertreated hypertension, intra-arterial blood pressure > 140/90 mmHg, and serum creatinine > 1.5 mg/dl before angiography. Renal artery stenosis (RAS) was defined as a narrowing ?50% of the diameter. We found that the prevalence of RAS was 17.6% and that according to logistic regression, the prevalence was 2.113 in the female gender (p?0.001), 1.82 in patients over 65 years old (p=0.002), 2.095 times more in SVD (p=0.043), 3.779 times more in 2vd (p?0.001), 5.004 times more in 3vd (p?0.001), and was significantly more in hypertensive patients (p?0.001). Conclusion: Considering that angiography is the best diagnostic management for detecting RAS, we recommend that concomitant renal and cardiac angiography must be done in hypertensive, female gender, age over 65 years and multi vessel CAD
