Declining Risk of Sudden Death in Heart Failure
Why the study?
Does the cumulative use of evidence-based medications reduce rates of sudden death over time in ambulatory patients with heart failure with reduced ejection fraction?
Population
Ambulatory patients with heart failure with reduced ejection fraction who were enrolled in clinical trials

Implication
Declining sudden death rates may reflect cumulative medication benefits in HFrEF; leaves open causal confirmation in randomized trials.

The risk of sudden death in HFrEF patients has declined substantially over time, likely reflecting the cumulative benefit of modern evidence-based medical therapies.
