Key result
Ejection fraction improvement after revascularization independently predicted a lower risk of cardiac death (HR 0.26; P=0.02).
Why the study?
Does ejection fraction improvement after revascularization predict long-term survival in patients with ischaemic left ventricular systolic dysfunction?
Cohort (n=87)
Does ejection fraction improvement after revascularization predict long-term survival in patients with ischaemic left ventricular systolic dysfunction?
Hazard Ratio: 0.26
p-value: p=0.02
Ejection fraction improvement after revascularization is an independent predictor of long-term survival in patients with ischemic LV dysfunction, with myocardial viability adding incremental prognostic value.
No takes yet. Share an insight, caveat, or question.
May inform post-revascularization risk stratification in ischemic LV dysfunction; leaves open whether viability assessment should guide therapy.
Joshi et al. (2011) conducted a cohort in ischaemic left ventricular systolic dysfunction (n=87). Ejection fraction improvement vs. No ejection fraction improvement was evaluated on cardiac death (HR 0.26, p=0.02). Ejection fraction improvement after revascularization independently predicted a lower risk of cardiac death (HR 0.26; P=0.02).
