Chronic HF outcomes similar across LVEF; leaves open targeted study of non-cardiac factors in prospective cohorts.
Does preserved LVEF compared to reduced LVEF affect mortality and readmission rates in patients hospitalized with chronic heart failure?
Prognosis in chronic heart failure is similar regardless of whether LVEF is reduced or preserved, with non-cardiac factors like renal dysfunction and anemia being significant prognostic determinants.
Miyagishima et al. (2008) studied this question.
