Table 2 Clinical variables of patients with combined chronic heart failure and chronic kidney disease, according to severity of atherosclerotic renal artery stenosis by magnetic resonance angiography

From: Atherosclerotic renal artery stenosis is prevalent in cardiorenal patients but not associated with left ventricular function and myocardial fibrosis as assessed by cardiac magnetic resonance imaging

  No stenosis (n = 16) Unilateral stenosis 50-70% (n = 5) Unilateral stenosis >70% (n = 8) Bilateral stenosis >50% or previous bilateral PTA (n = 8) p-value
