Abstract

ABSTRACT Background The opportunity for percutaneous treatment of coronary artery disease in unprotected left main artery has increased. This treatment possibility is based on favorable results in the literature. The objective of this study was to compare the demographic profile and results of percutaneous coronary intervention in patients with unprotected left main coronary artery lesions. Methods The period from 2006 to 2016 was analyzed, divided into three intervals – 2006 to 2008, 2009 to 2011 and 2012 to 2016, based [...]

Highlights

In recent years, the possibility of treating coronary disease in the unprotected left main coronary artery (LMCA) by percutaneous coronary intervention (PCI)J Transcat Intervent. 2019;27:1-6has increased
There was a significant difference between the periods in the variables smoking, clinical presentation, and history of previous PCI in the interval from 2012 to 2016
Primary PCI or the prevalence of Thrombolysis in Myocardial Infarction (TIMI) flow 0/1 before the intervention were more often reported in the 2006-2008 period

Summary

Introduction

The possibility of treating coronary disease in the unprotected left main coronary artery (LMCA) by percutaneous coronary intervention (PCI)J Transcat Intervent. 2019;27:1-6has increased. In 2016, the NOBLE (Nordic-Baltic-British Left Main Revascularization Study), demonstrated that, despite similar mortality rates, the 5-year risk of major adverse cardiovascular events (MACE) was higher after PCI as compared to CABG.[5] In 2016, Nerlekar et al published a meta-analysis limited to randomized clinical trials and found no differences in the results regarding clinical safety when comparing PCI using drug-eluting stents and CABG, in low surgical risk patients. In their conclusions, they stated CABG is a more effective strategy for revascularization, since PCI is associated with significantly higher rates of repeat revascularization and myocardial infarction in the long-term follow-up.[6]
