Key result
Higher Killip-Kimball class was significantly associated with increased in-hospital mortality in octogenarian patients with acute coronary syndrome, ranging from 5% in class I to 40% in class IV.
Why the study?
Contemporary data on the Killip-Kimball Classification in elderly populations with ACS is limited.
Does a higher Killip-Kimball Classification predict increased in-hospital mortality and morbidity in octogenarian and nonagenarian patients with ACS undergoing cardiac catheterization?
Cohort (n=133)
Yes
Does a higher Killip-Kimball Classification predict increased in-hospital mortality and morbidity in octogenarian and nonagenarian patients with ACS undergoing cardiac catheterization?
p-value: p=0.002
The Killip-Kimball classification remains a reliable and valid prognostic tool for predicting in-hospital mortality and acute kidney injury in octogenarian patients presenting with acute coronary syndrome.

May aid risk stratification in octogenarian ACS; leaves open prospective validation before guiding care.
Ramonfaur et al. (2020) conducted a cohort in Acute Coronary Syndrome (n=133). Killip-Kimball Classification vs. Lower Killip-Kimball Class was evaluated on In-hospital mortality (p=0.002). Higher Killip-Kimball class was significantly associated with increased in-hospital mortality in octogenarian patients with acute coronary syndrome, ranging from 5% in class I to 40% in class IV.
