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 present in 70 patients (14%). In 346 individuals of the study population, significant CAD was present (69.2%). Significant RAS was more common (18.4%) in this group. Older age, higher intra-arterial systolic blood pressure (SBP) and pulse pressure (PP) at the time of catheterization, and 3-vessel coronary artery disease (CAD) were associated with significant RAS in univariate analysis. Relationship between involved locations of coronary arteries [Left anterior descending (LAD), left circumflex (LCX), Right Coronary Artery (RCA), and their ostioproximal portions] and RAS were significant except for left main (LM) disease. In multivariate model, age more than 62 years, SBP greater than 150 mmHg, PP in excess of 60 mmHg and RCA involvement were independent predictors of significant RAS. Conclusion Simultaneous renal angiography following coronary angiography might be justified in patients with significant RCA disease who are older with increased levels of intra-arterial SBP and PP.

Background: The association between extent and severity of coronary artery disease (CAD) and renal artery stenosis (RAS) has been well established in many studies. The aim of this study was to assess the incidence and severity of RAS in patients with CAD. Methods: Coronary angiogram (CAG) and renal angiogram was done in standard protocol. A total of 95 patients was included in the study and divided into two groups according to the presence of significant renal artery stenosis. In Group I 45 patients were having normal or insignificant renal artery stenosis. In Group II 50 patients were having significant renal artery stenosis. All data were recorded systematically in preformed data collection form. Results: In Group I, most common CAG findings were single vessel disease (SVD) (91.1%), triple vessel disease (TVD) (2.2%) and double vessel disease (DVD) (6.7%). No patients in Group I had Left Main (LM) disease. In Group II, most common CAG findings were DVD (42.0%) followed by SVD 32.0%, TVD 26.0% and LM 8.0%. There is statistically significant difference in Vessels Score, Friesinger Score and Leaman Score between the groups (p<0.05). Conclusion: The study revealed significant association between atherosclerotic renal artery stenosis (RAS) and severity of coronary artery disease (CAD). This indicates significant atherosclerotic renal artery stenosis (RAS) predict the severity of coronary artery disease.

This retrospective observational study aimed to see the angiographic association of atherosclerotic renal-artery stenosis (ARAS) with coronary artery disease in Bangladesh. It was conducted in department of cardiology, University Cardiac Centre, Bangabandhu Sheikh Mujib Medical University, Dhaka from January 2007 to January 2008. A total of 250 patients with coronary artery involvement, on non-emergent coronary angiogram who underwent either selective or nonselective renal angiography were enrolled in this study. Among 250 patients, 52 (20.8%) patient had single vessel disease (SVD), 49 (19.6%) and 149 (59.6%) had double vessel disease (DVD) and triple vessel disease (TVD) respectively. ARAS was detected in 37.2% or 93 patients. ARAS tends to increase with age. In age group of 30-40, ARAS is 7.4% whereas in age group of 51-60 years it is 41%. The incidence of ARAS is high in 50.25±9.98years; p=0.0001. 33.3% male patients with CAD had ARAS whereas it was 44.3% in female patients with CAD. ARAS is more common in female 44.3% vs 33.3%; p=0.02. ARAS prevalence increased with the number of stenosed coronary arteries (3.8% in 1-vessel, 26.5% in 2-vessel, 52.3%in 3-vessel CAD; p=.0001.). Hypertension and angiographically proven CAD were independent predictors of ARAS (p=0.0001). In conclusion, ARAS prevalence and severity increases with the number of arterial territories involved and CAD severity. Hypertension and 2-3-vessel-CAD were identified independent predictors of ARAS.   doi:10.3329/uhj.v4i2.2069 University Heart Journal Vol. 4 No. 2 July 2008 p24-27

Simultaneous Assessment

Background: Coronary artery disease (CAD) is the first cause of mortality in developed and developing countries, including Iran. Identifying high-risk patients can save many from morbidity and mortality. Renal artery stenosis (RAS) seems to be equivalent to CAD in patients with cardiovascular risk. Objectives: The present study aimed to determine the prevalence, severity, and extent of RAS and its predictors in patients with confirmed CAD on coronary angiography. Patients and Methods: All patients suspected of ischemic heart disease (IHD), who underwent diagnostic coronary angiography at Heshmat heart hospital, Iran were recruited (May 2015 to June 2016). Patients with confirmed CAD underwent non-selective renal angiography, which was categorized as mild, moderate or severe based on luminal diameter narrowing more than normal >0% to 50%, between 50%-70% and more than 70%, respectively. Results: Of 233 patients, RAS was observed in 123 (53%). Around 20% were mild, 10% were moderate and 23% were severe. Additionally, RAS in 37% was unilateral and in 16% were bilateral. Besides,19%, 25% and 56% of patients had atherosclerosis in one, two and three vessels, respectively. There was no correlation between the CAD severity and severity of RAS (P=0.807). Conclusions: Higher prevalence of RAS in patients with hyperlipidemia (60% vs. 40%) was detected. Its association with variables affecting CAD indicates that RAS can be a predictor of CAD. Therefore, simultaneous assessment of RAS in coronary angiography can be a good screening method for CAD beside earlier diagnosis of kidney disease.

Demographic Distribution

Background: Aim of our present study was to evaluate the extent of Renal Artery Stenosis(RAS) in patients with Coronary Artery disease (CAD) in context of Bangladesh demographic distribution. Methods: Total 100 patients with renal artery disease were randomized from a pool of 1200 patients who were underwent routine diagnostic coronary angiogram for the evaluation of extent of their CAD. Renal arteries were studied at the same time. Among the patients, Male: 64 and Female: 36. Mean age were for Male: 62yrs, for Female: 58 yrs. Associated CAD risk factors were Dyslipidemia, High Blood pressure, Diabetes Mellitus, Positive FH for CAD and Smoking. Results: Our study results show 100 patients (12% of the sample) had RAS lesion out of total 1200 patient who underwent routine CAG. Sex distribution is male 64 (64%), Female 36 (36%). Among the study group; 79 (79%) were hypertensive; 57 (57%) were Dyslipidemic, 54 (54%) patients were Diabetic, 27 (27%) were smoker (all male) and 18(18%) were having positive FH for CAD. Female patients were more obese and developed CAD in advanced age (male: 53.5 Versus Female:64 yrs). We found that the Prevalence’s of RAS is more in patients with TVD (43%), followed by DVD (10%) and SVD (10%), Minor to mod CAD (14%) and angiographically normal coronaries (23%). Significant (>50% Stenosis) Left renal artery stenosis were found in 27 patient and 23 had significant Right renal artery stenosis. Total 8 patents had significant both renal artery stenosis. Conclusion: Renal artery stenosis is one of the most important peripheral vascular disease, needing to be diagnosed early and subsequent intervention to keep continuity of renal blood flow. In the present study, we found that the significant association of Renal Artery Stenosis in patients with CAD. Incidence of RAS is more in patients with TVD. Therefore, we recommend routine Renal angiogram during coronary angiography.
