Data on the outcome of young patients after coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) are scarce. Data on 2,209 consecutive patients aged≤50 years who underwent CABG or PCI were retrospectively collected from 15 European institutions. PCI and CABG had similar 30-day mortality rates (0.8% vs 1.4%, p=0.27), late survival (at 5 years, 97.8% vs 94.9%, p=0.082), and freedom from stroke (at 5 years, 98.0% and 98.0%, p=0.731). PCI was associated with significantly lower freedom from major adverse cardiac and cerebrovascular events (at 5 years, 73.9% vs 85.0%, p<0.0001), repeat revascularization (at 5 years, 77.6% vs 92.5%, p<0.0001), and myocardial infarction (at 5 years, 89.9% vs 96.6%, p<0.0001) compared with CABG. These findings were confirmed in propensity score-adjusted and matched analyses. Freedom from major adverse cardiac and cerebrovascular events after PCI was particularly low in diabetics (at 5 years, 58.0% vs 75.9%, p<0.0001) and in patients with multivessel disease (at 5 years, 63.6% vs 85.1%, p<0.0001). PCI in patients with ST elevation myocardial infarction was associated with significantly better 5-year survival (97.5% vs 88.8%, p=0.001), which was driven by its lower 30-day mortality rate (1.5% vs 6.0%, p=0.017). In conclusion, patients aged≤50 years have an excellent immediate outcome after either PCI or CABG with similar long-term survival when used according to the current clinical practice. PCI was associated with significantly lower freedom from myocardial infarction and repeat revascularization.
