Are chronic kidney disease and worsening renal function associated with increased mortality risk in patients with heart failure?
Both chronic kidney disease and worsening renal function are strongly associated with increased mortality in patients with heart failure.
Across all subgroups of patients with HF, CKD, and WRF are prevalent and associated with a strongly increased mortality risk, especially CKD. Specific conditions may predict the occurrence of WRF and thereby poor prognosis.
Damman et al. (2013) studied this question.
