Introduction
Coronary artery bypass grafting (CABG) has been considered to be the proven therapeutic choice for coronary artery disease. However, percutaneous coronary intervention (PCI) with drug-eluting stents is increasingly used for extensive coronary artery disease with contradictory results. The aim of this study is to compare immediate- and mid-term results of CABG where skeletonized internal mammary artery (IMA) was used as in situ graft versus PCI with serolimus drug eluted stents (SES) in single-vessel left anterior descending artery (LAD) disease.
Methods
In 2014–2022, 938 patients treated for isolated LAD revascularization were included in this study. Among them, there were 346 patients with CABG-IMA and 592 patients with SES-PCI. CABG-IMA patients (n = 266) were compared with SES-PCI patients (n = 266) in propensity score-matched method.
Primary outcome measures were identified as all-cause mortality at 30 days and 3 years after surgery, while secondary outcome measures were length of hospital stay and the incidence of postoperative major adverse cardiovascular and cerebrovascular events (MACCE).
Results
Increased incidence for post procedural MACCE after PCI was recorded (CABG = 1.2% vs. PCI = 5.3%; p < 0.05). There was no difference in immediate-term (30 days: CABG = 1.2% vs. PCI = 1.5%; p = ns) and mid-term (3 years: CABG = 3.7% vs. PCI = 4.5%; p = ns) mortality between the groups. Patient after SES-PCI had shorter length of hospital stay (CABG = 7.7 days vs. PCI = 3.8 days; p < 0.05).
Conclusion
The results of the study indicated that CABG-IMA performed at the time of myocardial revascularization in single-vessel LAD disease is better than SES-PCI. Our conclusion is independent of traditionally accepted risk factors incorporated in the Logistic EuroSCORE II (European System for Cardiac Operative Risk Evaluation) and SYNTAX score II (Synergy Between Percutaneous Coronary Intervention with TAXUS and Cardiac Surgery Score II) and is exclusively method related.
