A Decade of Improvement in the Clinical Outcomes of Percutaneous Coronary Intervention for Multivessel Coronary Artery Disease

Hospital percutaneous coronary intervention volume and patient mortality, 1998 to 2000

“…There are several potential explanations for the comparable mortality rates among patients treated in medium, high, and very high PCI volume hospitals. Percutaneous coronary intervention technology has changed markedly since the first studies of hospital PCI volume and outcomes (14,29,30). Although the adoption of coronary stents during the mid-1990s improved patient outcomes (13,14,30 -32), previous studies indicated that patients undergoing PCIs involving stents at higher volume centers continued to have lower mortality rates than patients undergoing PCIs involving stents at lower volume centers (13,19,23,32,33).…”

Routine intravascular ultrasound guidance of percutaneous coronary intervention

“…The complication rate appears to be highest in patients with unstable angina or acute MI (2.9%), as compared with patients with stable angina pectoris and asymptomatic patients (0.8 and 0.4%, respectively; p Ͻ 0.01). In an era of significant improvements in procedural safety (33), this limitation may assume greater significance in future analysis of the relative merits of IVUS-guided stent implantation.…”

A pilot randomized trial of pentoxifylline for the reduction of periprocedural myocardial injury in patients undergoing elective percutaneous coronary intervention

“…Despite the recent technical and medical advances in the performance of PCI, it contains some adverse clinical outcomes [4]. Given this fact, periprocedural myocardial injury (PMI) is the mortality-related complication of PCI that significantly affects the early and late outcomes of patients who are undergoing PCI [5].…”
