Background
Long-termcomparative data on clinical outcomes between percutaneous coronaryintervention (PCI) and coronary artery bypass grafting (CABG) according to leftventricular (LV) function are limited.
Methods
: From theAsan-Multivessel registry, we identified 9,856 patients who underwent CABG(n=4,107) or PCI (n=5,749). LV function was categorized according to LVEF asnormal function (LVEF ≥55%),mild (LVEF ≥45% to <55%),moderate (LVEF ≥35% to <45%), or severe (LVEF<35%) dysfunction. The primary composite outcome was a composite of death,spontaneous myocardial infarction, or stroke at 10 years. To adjust differencesof baseline risk factors, propensity-score matching and inverse probability of treatment weighting (IPTW) were used.
Results
Among 9,856 eligible patients, 7350 (74.5%) patients had normal LVEF and 1288 (13.0%), 715(7.2%), and 503 (5.1%) had mild, moderate, and severe LV dysfunction atbaseline, respectively. After propensity matching, PCI, as compared with CABG,had similar risks for the primary composite outcome in patients with normalLVEF (adjusted hazard ratio [HR] 0.97; 95% confidence interval [CI] 0.82−1.15; P=0.71), moderate LVEF (HR 1.10; 95% CI 0.74−1.64; P=0.641), or severe LVEF (HR 1.17; 95% CI 0.77−1.77;P=0.465). In patients with mild LVEF, PCI had a higher risk of primary outcomecompared to CABG (HR 1.15; 95% CI 1.13−2.13; P=0.006) (Figure and Table1). Afteradjustment using IPTW, however, the risk of the primary composite outcome wasnot significantly different between PCI and CABG according to LVEF (Table2).
Conclusion
In patients withmultivessel disease following myocardial revascularization, there were nosignificant differences in the primary composite outcome of death, MI, orstroke at 10 years between PCI and CABG according to left ventricular function.
