Frequency of Coronary Artery Disease in Angiographically Confirmed Patients of Renal Artery Stenosis with Hypertension
Journal Title: International Journal of Medical Research Professionals - Year 2017, Vol 3, Issue 3
Abstract
Background: In hypertensive patients who undergo renal angiography to investigate renal artery stenosis (RAS) there are no recommendations regarding when to investigate coronary artery disease (CAD). Moreover, the predictors of CAD in patients with RAS are not clear. Objectives: To evaluate the frequency and the determinants of CAD in hypertensive patients with RAS referred to renal angiography. Methods: 42 consecutive patients with high clinical risk suggesting the presence of RAS systematically underwent renal angiography and coronary angiography during the same procedure. Significant arterial stenosis was defined by an obstruction ≥ 50% to both renal and coronary territories. Results: Of 42 consecutive patients with angiographically confirmed RAS; 28 (66.7%) had significant CAD in one or more coronary arteries. 6 patients (14.2%) had single coronary vessel disease, 11 (26.1%) had two-vessel disease and 11 (26.1%) had multivessel disease. On the other hand 26/42 (61.9%) had unilateral RAS and 16/42 (38.1%) had bilateral RAS. The clinical characteristics such as age, gender and smoking were not different between both groups while diabetes and hyperlipidemia had a strong association. The severity of CAD and RAS were also correlated. None developed complications as a result of the two consecutive procedures. Conclusion: The data suggest that in patients with RAS the frequency of CAD is high and cannot be predicted on clinical grounds alone, therefore coronary angiography should be routinely recommended in the same setting.
