The prevalence of Renal Artery Stenosis in ischemic heart disease patients undergoing coronary angiogram.
Pak J Cardiol Jan ;15(3):103-7.

Objective: To understand the presence of renal artery stenosis (RAS) in patients with coronary artery disease (CAD) and the correlations among coronary artery disease, renal artery stenosis, hypertension and renal insufficiency. METHODS: A prospective observational study carried out at Punjab Institute of Cardiology from January 2003 to July 2003. Convenience based abdominal aortograms was performed to assess the anatomy of renal arteries in 155 patients who were scheduled for coronary angiography. RESULTS: Of the total patient cohort 25 (16. 1 %) had significant (>or=50%) RAS. Out of these 4 (2.6%) patients had bilateral RAS. 6 (3.9%) patients had left sided RAS and 15 (9.7%) patients had right sided RAS. All 25 (100%) patients suffering from RAS had significant CAD. 19 (76%) had triple vessel disease, 5 (20%) had two vessel disease and 1 (4%) had single vessel disease. 64% patients suffering from RAS had hypertension. 3 (12%) patients had elevated serum creatinine. CONCLUSION: RAS is a frequent finding in patients with CAD, especially in triple vessel disease patients. Hypertension is closely related to RAS. Abdominal/ renal angiogram may be recommended in patients of triple vessel disease. Key Words: Renal artery stenosis, Coronary artery disease, Hypertension.
