“…In a recent study, based on color Duplex sonography in 269 patients RAS was present in 11% of the patients in the 50-59 years age group, 18% in the 60-69 years and 23% at the age of 70 years and above [21]. The association between old age and RAS in our study was similar to that described in other researches and more studies have shown that patients with significant RAS are older [22][23][24]. Here, there is a strong and independent relation between old age and RAS which shows a later or slower start of atherosclerosis in renal arteries rather than the coronary or other peripheral vascular atheroscleroses [25].…”

BackgroundRenal 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.ObjectivesThis study was performed to determine the prevalence and to identify the predictors of RAS in hypertensive patients undergoing coronary artery angiography.Patients and MethodsIn a cross-sectional study from August 2008 to August 2009, 481 patients with HTN and suspected CAD underwent selective coronary and renal angiography for screening and predicting RAS. RAS was defined as a higher than 50% stenosis in the renal artery lumen. Multivariate analysis of factors associated with the presence of RAS were examined using a logistic regression model.ResultsThe mean ± standard deviation of age was 59.25 ± 10.81 years and 50.3% were men. According to angiographic data, 425 patients (88.4%) had CAD, while 56 (11.6%) had normal coronary arteries. RAS was seen in 94 (22%) patients with CAD. The multivariate logistic regression analysis identified only age (P < 0.001) and the number of significant coronary lesions (P < 0.001) as independent predictors of RAS. Gender, smoking, congestive heart failure, diabetes mellitus (DM), hyperlipidemia (HLP) and body mass index (BMI) were not independent predictors.ConclusionsThis study suggests that in the management of patients with RAS, risk factors should most likely be considered as beneficial. In addition, the clinical and angiographic features are helpful in predicting its presence in elderly patients with CAD.

“…The results of our study showed that there was significant relationship between family history of coronary artery disease and significant RAS as there was increased incidence of significant renal artery stenosis in patients with family history of coronary artery disease. In contrary to our study El-Mawardy et al (13) showed that there was no significant relationship between incidence of RAS and family history of coronary artery disease (p value = 0.74).…”

“…The results of our study showed that there was no significant relationship between smoking and incidence of significant renal artery stenosis. In agreement with our study Carmelita et al (12) didn't find significant correlation between smoking and increased incidence of significant RAS (p value = 0.25) also El-Mawardy et al (13) found that there was no significant increase in incidence of RAS with smoking (p value = 0.96). Unlike our study Santanu et al (7) revealed that only smoking was the risk factor that have significant correlation with RAS (p value = 0.008).…”

Background: Cardiovascular disease is the leading cause of death. Importantly, it remains the foremost cause of preventable death globally.Atherosclerotic renal artery stenosis (ARAS) is the most common primary disease of the renal arteries and it is associated with two major clinical syndromes; ischemic renal disease and hypertension. Objective: To determine the incidence and predictors of renal artery stenosis in the multivessel coronary artery disease patients. Patients and Methods:The study included 100 patients undergone coronary angiography at Matrouh Specialized Cardiac Surgery and Interventional Catheterization Center and proved to have multivessel coronary artery disease during the period from January 2014 to April 2016. They were 74 males and 26 females. Their age ranged between 50-70 years with a mean of 57.28 ± 6.74 years. Results:The study showed that 16 patients (16%) had renal artery stenosis. All patients with renal artery stenosis had unilateral RAS and no patients had bilateral RAS. Significant renal artery stenosis (> 50% diameter stenosis) was found in 10 patients (10%) and nonsignificant RAS was found in 6 patients (6%). The left renal artery was singly involved in 6 patients (6%) and the right renal artery was singly involved in 10 patients (10%). There was no significant relationship between the number of coronary arteries affected and incidence of significant renal artery stenosis. Also there was no significant relationship between the level of serum creatinine and incidence of significant renal artery stenosis. Conclusion: Renal angiography was a reliable method to assess renal artery stenosis and may be more important in hypertensive patients with multivessel coronary artery disease.

Prevalence of renal artery stenosis in patients undergoing cardiac catheterization

To investigate the prevalence of significant renal artery stenosis (RAS ≥50%), and to identify clinical predictors for significant RAS in patients with an elevated cardiovascular risk, such as those affected by ischemic heart disease. In patients with an elevated cardio-vascular risk, both atherosclerotic renovascular disease and coronary artery disease (CAD) are likely to occur. Prospectively from April 2007 to March 2008, all consecutive patients with ischemic heart disease undergoing non-emergent cardiac catheterization were also evaluated for atherosclerotic RAS by renal arteriography. A RAS ≥50% was considered as significant. A total of 1,298 patients underwent cardiac and renal angiography. Significant RAS was found in 70 out of 1,298 patients (5.4%). The presence of peripheral vascular disease, eGFR <67 ml/min/1.73 m(2), age >66 years, dyslipidemia, CAD severity and pulse pressure >52 mmHg were independent clinical predictors of significant RAS, and jointly produced a ROC AUC of 0.79 (95% CI 0.73-0.85, P < 0.001). Based on these data, a prediction rule for significant RAS was developed, and it showed an adequate predictive performance with 64% sensitivity and 82% specificity. In a large cohort of patients undergoing coronary angiography, significant RAS is a relatively rare comorbidity (5.4%). A model based on simple clinical variables may be useful for the clinical identification of high CV risk patients who may be suitable for renal arteriography at the time of cardiac catheterization.
