Kerzner et al evaluated risk factors for mortality in patients with heart failure, after separating patients by age and left ventricular ejection fraction. The authors are from Washington University in St Louis, Missouri.
Breakpoints for groups:
(1) age < 75 years vs >= 75 years
(2) left ventricular ejection fraction >= 40% (preserved) vs < 40% (reduced)
• Higher diuretic dose at discharge may reflect renal dysfunction.
Implementation note:
• Much of the data deals with intervals, making implementation difficult. I tried to approximate a risk score, but this has not been tested or validated.
