Abstract
Aims To investigate the prognostic impact of atherosclerotic renovascular disease in patients with chronic heart failure. Methods and Results Patients with heart failure due to left ventricular systolic dysfunction underwent cardiac magnetic resonance imaging and contrast-enhanced magnetic resonance angiography. Renal artery stenosis (RAS) was defined as a luminal narrowing >50. Of the 366 patients investigated, 112 (31) had RAS, of whom 41 had bilateral RAS. Patients with RAS were older (P < 0.001), had higher blood pressure (P < 0.001), and worse renal function (P= 0.001). In addition, these patients had more admissions and more prolonged hospital stays because of vascular events (0.09 ± 0.26 vs. 0.02 ± 0.16 admissions/per patient/year; P < 0.001; and 1.26 ± 5.79 vs. 0.31 ± 2.54 days/per patient/year; P < 0.001, respectively) and worse prognosis (hazard ratio 1.60, 95 confidence interval 1.102.34, P 0.015). However, in multivariable analysis, a history of diabetes mellitus, decreasing haemoglobin, and increasing left ventricular end-systolic volume index, but not age and RAS, were independently related to outcome. Conclusion sRAS is a common finding in patients suffering from heart failure. Although it is associated with an increased vascular morbidity, it is not an independent predictor of mortality.
