Overview

Nearly threefold higher mortality in octogenarians with ACS after emergent angiography warrants caution; leaves open whether hemodynamic strategies improve outcomes.

Structured PICO

Does emergent coronary angiography and intervention yield similar in-hospital outcomes in octogenarians compared to younger patients with acute coronary syndrome?

P
Population
1,655 patients with acute coronary syndrome (ACS) who underwent emergent coronary angiography, comprising 193 octogenarians (mean age 83 years) and 1,462 younger patients (mean age 64 years).
I
Intervention
Emergent coronary angiography and subsequent interventions (percutaneous transluminal coronary angioplasty [PTCA] or coronary artery bypass grafting [CABG]) in octogenarians.
C
Comparator
Emergent coronary angiography and subsequent interventions in younger patients.
O
Outcome
In-hospital mortality.hard clinical

Octogenarians with ACS undergoing emergent coronary angiography have a nearly three-fold higher in-hospital mortality compared to younger patients, largely driven by impaired hemodynamics rather than procedural failure.
