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., (Copyright © 2014 Elsevier Inc. All rights reserved.)

This study was planned to identify the determinants of outcome after coronary artery bypass (CABG) in young patients. Data on 592 patients aged ≤50 years who underwent CABG from 9 European institutions were collected retrospectively. Twenty-eight percent of patients received at least 2 arterial grafts. Clopidogrel was used at discharge in 16.2% and statins in 67.2% of patients. Freedom from major adverse cardiac and cerebrovascular events at 1, 3, and 5 years was 93.8%, 90.1%, and 85.0%; survival rate was 98.3%, 96.3%, and 94.9%; freedom from myocardial infarction was 96.3%, 95.1%, and 92.5%; and freedom from repeat revascularization was 96.3%, 95.1%, and 92.5%, respectively. Neither types of grafts nor medication at discharge had any impact on the late outcome. Age <40 years (relative risk [RR] 2.19, 95% confidence interval [CI] 1.17 to 4.11), diabetes (RR 1.71, 95% CI 1.02 to 2.88), estimated glomerular filtration rate <60 ml/min/1.73 m(2) (RR 2.44, 95% CI 1.26 to 4.72), non-ST-elevation myocardial infarction/ST-elevation myocardial infarction (RR 2.12, 95% CI 1.27 to 3.55), emergency procedure (RR 2.34, 95% CI 1.13 to 4.88), and left ventricular ejection fraction <30% (RR 3.18, 95% CI 1.41 to 7.16) were independent predictors of major adverse cardiac and cerebrovascular events. Patients with left ventricular ejection fraction <30% had a particularly poor survival rate (at 5 years 67.7% vs 96.1%; adjusted analysis RR 14.01, 95% CI 5.16 to 38.03). Poor left ventricular function, myocardial infarction, diabetes, renal failure, and age <40 years are major determinants of late outcome after CABG in young patients. In conclusion, data from this real-world registry indicate that multiple arterial grafts and statin treatment are largely underutilized in these patients., (Copyright © 2014 Elsevier Inc.
