Sequencing of medical therapy in heart failure with a reduced ejection fraction

The management of heart failure with a reduced ejection fraction is a true success story of modern medicine. Evidence from randomised clinical trials provides the basis for an extensive catalogue of disease-modifying drug treatments that improve both symptoms and survival. These treatments have undergone rigorous scrutiny by licensing and guideline development bodies to make them eligible for clinical use. With an increasing number of drug therapies however, it has become a complex management challenge to ensure patients receive these treatments in a timely fashion and at recommended doses. The tragedy is that, for a condition with many life-prolonging drug therapies, there remains a potentially avoidable mortality risk associated with delayed treatment. Heart failure therapeutic agents have conventionally been administered to patients in the chronological order they were tested in clinical trials, in line with the aggregate benefit observed when added to existing background treatment. We review the evidence for simultaneous expedited initiation of these disease-modifying drug therapies and how these strategies may focus the heart failure clinician on a time-defined smart goal of drug titration, while catering for patient individuality. We highlight the need for adequate staffing levels, especially heart failure nurse specialists and pharmacists, in a structure to provide the capacity to deliver this care. Finally, we propose a heart failure clinic titration schedule and novel practical treatment score which, if applied at each heart failure patient contact, could tackle treatment inertia by a constant assessment of attainment of optimal medical therapy.
