Comparison of 30-day and 5-year outcomes of percutaneous coronary intervention versus coronary artery bypass grafting in patients aged≤50 years (the Coronary aRtery diseAse in younG adultS Study).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.
Determinants of outcome after isolated coronary artery bypass grafting in patients aged ≤50 years (from the Coronary aRtery diseAse in younG adultS study).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.
