Key result
Pre-operative CMR left ventricular ejection fraction (OR 0.93; 95% CI 0.87-0.99) and stroke volume index (OR 1.07; 95% CI 1.00-1.14) predicted increased admission cost in elective CABG.
Why the study?
Do pre-operative CMR findings predict increased resource utilization in patients undergoing elective CABG?
Cohort (n=458)
Do pre-operative CMR findings predict increased resource utilization in patients undergoing elective CABG?
Odds Ratio: 0.93 (95% CI 0.87–0.99)
p-value: p=0.03
Pre-operative CMR findings, specifically LVEF and stroke volume index, can predict increased admission costs and duration in patients undergoing elective CABG.
No takes yet. Share an insight, caveat, or question.
May flag higher-cost elective CABG patients; leaves open whether routine CMR improves resource allocation.
Berry et al. (2008) conducted a cohort in elective coronary artery bypass grafting (n=458). Pre-operative cardiac magnetic resonance (CMR) findings was evaluated on Increased admission cost (greater than median) (OR 0.93, 95% CI 0.87-0.99, p=0.03). Pre-operative CMR left ventricular ejection fraction (OR 0.93; 95% CI 0.87-0.99) and stroke volume index (OR 1.07; 95% CI 1.00-1.14) predicted increased admission cost in elective CABG.
