Risk assessment for percutaneous coronary intervention of the unprotected left main coronary artery in a real-world population.

Abstract：

BACKGROUND:Available clinical and angiographic scoring systems fail to predict clinical outcomes in real-world patients undergoing revascularization of the unprotected left main coronary artery (ULMCA). METHODS:We prospectively assessed major adverse cardiac and cerebrovascular events (MACCE) in a real-world population undergoing percutaneous coronary intervention (PCI) for ULMCA disease. Cumulative risk-adjusted mortality in our patients was compared with expected mortality at 30 days based on logistic EuroSCORE and SYNTAX SCORE. Similarly, we plotted cumulative risk-adjusted MACCE at 1 year based on SYNTAX SCORE. Finally, both scores were combined in 1 year Global Risk Charts, including the use of drug-eluting stents (DES), diabetic status, and several factors precluding coronary surgery. RESULTS:Over a 12-year period, 240 patients underwent elective (76%) or urgent (24%) PCI of the ULMCA. Median logistic EuroSCORE and SYNTAX SCORE were 8.7% (3.5; 21) and 23% (14; 31). During the first year of follow-up, 89 patients presented MACCE (37.1%) (46 deaths [19.2%], 18 acute myocardial infarctions [7.5%], 45 revascularizations [18.8%] and 4 strokes [1.7%]). Cumulative risk-adjusted mortality based on individual logistic EuroSCORE and SYNTAX SCORE pointed towards significant overestimation (+19 deaths) and underestimation (-35 deaths) of risk by these respective scoring systems. Similarly, the anatomic SYNTAX SCORE largely underestimated cumulative risk-adjusted MACCE (-60 MACCE). The Global Risk Charts provided a more balanced view on 1-year clinical outcome. CONCLUSION:An integrated risk evaluation combining EuroSCORE, SYNTAX SCORE, diabetic status, stent type and general condition, may predict outcomes more accurately awaiting validation in a larger and multicentre setting.
