frequency and predictors of renal artery stenosis in patients undergoing simultaneous coronary and renal catheterization

چکیده
background: atherosclerotic renal artery stenosis (aras) remains underdiagnosed due to its nonspecific demonstrations. we aimed to both estimate the frequency of aras in high-risk non-selected patients undergoing simultaneous coronary and renal catheterization and possibly identify a predictive model for aras using baseline clinical, laboratory, and coronary angiographic variables. methods: the records of 866 patients aged ≥ 21 years undergoing simultaneous coronary and renal angiography were retrieved for analysis from our computerized database. the degree of aras was estimated visually by experienced attending interventional cardiologists. lesions with an estimated stenosis of ≥ 50% were considered significant. multivariable stepwise logistic regression models were used to identify the risk factors predicting the presence and extent of aras. results: of a total of 866 consecutive patients undergoing renal angiography in conjunction with coronary angiography (mean age ± sd: 63.06 ± 10.32, ranging from 24 to 89 years), 454 (57%) were men. a total of 345 (39.8%) cases had significant aras, 77 (22.3%) of which were bilateral. using significant aras as the dependent variable, six variables were identified as the independent predictors significantly associated with the presence of aras, namely age, female sex (male sex was found to be a protector), hypertension, history of renal failure, left anterior descending artery (lad) stenosis > 50%, and left circumflex artery (lcx) stenosis > 50%. the gensini score was not found to be a predictor of the presence of aras, but it was more likely associated with a trend towards a more extensive aras (adjusted or = 1.00, 95% ci = 1.00-1.01; p value = 0.039). other independent determinants of the aras extent were the same as the predictors of the aras presence. conclusions: although risk versus benefit was not tested in this study, it seems that clinicians could consider renal catheterization in combination with coronary angiography particularly in female patients with advanced age and with significant coronary artery stenoses in the lad and lcx.

Relationship between Distribution of Coronary Artery Lesions and Renal Artery Stenosis in Patients Undergoing Simultaneous Coronary and Renal Angiography
AIMS We evaluated the relationship between distribution of lesions in coronary tree and atherosclerotic renal artery stenosis (RAS). METHODS AND RESULTS Data collected prospectively on 500 consecutive patients who underwent simultaneous renal angiography following coronary angiography. Overall prevalence of RAS was 26.2% (131 patients). Significant (≥50% luminal diameter stenosis) RAS was pre...
متن کاملPrevalence and predictors of renal artery stenosis in patients undergoing cardiac catheterization.
Renal artery stenosis (RAS) is recognized as a major co-morbid condition for patients with cardiovascular disease. Although the prevalence of RAS in Western countries has been reported as 13.5-18% in patients with suspected coronary artery disease (CAD) undergoing coronary angiography, there is little information available about the prevalence of RAS in Asian populations, which are less suscept...
متن کاملRelationship between coronary artery lesions distribution and renal artery stenosis in patients undergoing simultaneous coronary and renal angiography
Background: Atherosclerosis is by far the most common etiology of renal artery stenosis(RAS) in the elderly. RAS and coronary artery disease (CAD) originate from similar multiple risk factors for the development of atherosclerosis so that not surprisingly patients with RAS more commonly have CAD and vice versa.We aimed to find out if any association between distribution of coronary artery lesio...

BACKGROUND Renal artery stenosis (RAS) has been increasingly recognized in the recent years, especially in patients with coronary artery disease (CAD). RAS affects the patients with hypertension (HTN), but the exact prevalence is not known. OBJECTIVES This study was performed to determine the prevalence and to identify the predictors of RAS in hypertensive patients undergoing coronary artery ...
