Multifocal atherosclerosis poses significant diagnostic and therapeutic challenges in patients with coronary artery disease (CAD), arterial hypertension (AH), and renal artery stenosis (RAS).
The aim of this study was to investigate cardiorenal interactions in patients with CAD and atherosclerotic renal artery stenosis (ARAS).
Materials and Methods: 101 patients with CAD and AH (83 males, mean age 56.2 ± 8.04 years) were examined. All patients had cardiovascular comorbidities. Simultaneous coronary and renal angiography was performed via femoral access in all subjects. Chronic kidney disease (CKD) was diagnosed according to KDIGO (2021) criteria. The estimated glomerular filtration rate (eGFR) was calculated using the CKD-EPI equation. The follow-up period was 12 months, the primary endpoint was overall mortality.
Atherosclerotic renal artery stenosis (ARAS) was diagnosed in 25 (25%) patients with CAD and AH. Hemodynamically significant ARAS (≥70% stenosis) was observed in 16 (16%) patients, and moderate ARAS (50-70% stenosis) was found in 9 (9%) patients. Unilateral ARAS was present in 21 (84%) patients, while bilateral disease was diagnosed in 4 (16%).
A significant predominance of right coronary artery (RCA) lesions was established in the ARAS group—21 (84%) patients—compared to 36 (47%) in the non-ARAS group (χ² = 10.27; p = 0.002). Furthermore, in the subgroup with hemodynamically significant ARAS (≥70%), hemodynamically significant RCA stenosis was diagnosed in 13 (81%) patients (χ² = 6.10; p = 0.01).
Patients with CAD and AH combined with ARAS were significantly older than those without angiographically verified ARAS (p = 0.026). No significant differences in the frequency of clinical CAD symptoms were found between the groups.
CKD, defined as eGFR <60 ml/min/1.73 m², was present in 26 (26%) patients, including 10 (40%) in the ARAS group. The presence of reduced eGFR in patients with CAD and AH, combined with a long-standing history of hypertension (>10 years), increased the relative risk of detecting ARAS by 5.55-fold (95% CI 2.75–11.2, p <0.01). The findings from routine coronary angiography can be utilized to predict the presence of hemodynamically significant RAS in patients with multifocal atherosclerosis.
Simultaneous angiography of the coronary and renal arteries revealed atherosclerotic renal artery stenosis in one out of four patients with CAD. Patients with CAD and ARAS are older and have a higher prevalence of hemodynamically significant right coronary artery disease. The presence of CKD with reduced eGFR in hypertensive patients with CAD and significant RCA stenosis increases the relative risk of having hemodynamically significant renal artery stenosis by 5.55 times.
