ABSTRACT
There is a large spectrum of acute decompensated heart failure presentations resulting from the interaction between an acute precipitant and the patient's underlying cardiac and non-cardiac conditions. A robust classification scheme at admission is crucial for appropriate triage and targeted treatment of high-risk populations. Such a scheme should incorporate timely actionable items to generate immediate management decisions, including characteristics that suggest life-threatening clinical presentations, the factors that could be favourably modified by in-hospital interventions, such as correctable aetiologies and congestion/hypoperfusion status, and in-hospital trajectories determined by patient responses to inpatient treatment. In-hospital trajectories determine the intensity of escalation therapies and timing for initiation/up-titration of guideline-directed medical treatment. In the long term, some patients experience a progressive downsloping course culminating in advanced heart failure, while others maintain a relatively stable remitting-relapsing trajectory. For future clinical trials, a comprehensive classification scheme integrating in-hospital and long-term trajectories could profoundly affect study design by ensuring interventions are tested in more homogeneous patient populations and facilitating nuanced patient stratification.
