Comparative StudyCoronary Plaque Characteristics Associated With Reduced TIMI (Thrombolysis in Myocardial Infarction) Flow Grade in Patients With ST-Segment-Elevation Myocardial Infarction: A Combined Optical Coherence Tomography and Intravascular Ultrasound Study.
Previous studies reported that reduced TIMI (Thrombolysis in Myocardial Infarction) flow grade before procedure was associated with worse clinical outcomes in patients with ST-segment-elevation myocardial infarction undergoing primary percutaneous coronary intervention. The aim of this study was to identify specific morphological characteristics of the culprit plaque associated with poor TIMI flow grade at baseline in patients with ST-segment-elevation myocardial infarction using both optical coherence tomography and intravascular ultrasound. ⋯ ST-segment-elevation myocardial infarction patients with reduced TIMI flow grade at baseline have greater lipid burden, larger vessel sizes, and larger plaque areas.

Comparative StudyVery Long-Term (10 to 14 Year) Outcomes After Percutaneous Coronary Intervention Versus Coronary Artery Bypass Grafting for Multivessel Coronary Artery Disease in the Bare-Metal Stent Era.
Many of the previous randomized trials comparing percutaneous coronary intervention (PCI) with coronary artery bypass grafting (CABG) in patients with multivessel coronary artery disease reported equivalent or better survival with CABG as compared with PCI at 5-year follow-up. However, 5-year follow-up might be too short to evaluate the true differences in long-term clinical outcomes between PCI and CABG. ⋯ CABG as compared with PCI was associated with better 10-year survival in patients with multivessel coronary artery disease. However, the benefit of CABG compared with PCI on late mortality beyond 5 years was not observed in this study.

Randomized Controlled Trial Comparative StudyBilateral Internal Thoracic Artery Configuration for Coronary Artery Bypass Surgery: A Prospective Randomized Trial.
Bilateral internal thoracic arteries (BITA) have demonstrated superior patency and improved survival in patients undergoing coronary artery bypass grafting. However, the optimal configuration for BITA utilization and its effect on long-term outcome remains uncertain. ⋯ URL: http://www.clinicaltrials.gov. Unique identifier: NCT01666366.

Everolimus-Eluting Stents in Patients With Bare-Metal and Drug-Eluting In-Stent Restenosis: Results From a Patient-Level Pooled Analysis of the RIBS IV and V Trials.
Treatment of patients with drug-eluting stent (DES) in-stent restenosis (ISR) is more challenging than that of patients with bare-metal stent ISR. However, the results of everolimus-eluting stents (EES) in these distinct scenarios remain unsettled. ⋯ URL: http://www.clinicaltrials.gov. Unique identifiers: NCT01239953 and NCT01239940.
