Abstract

Background: We intended in this study to evaluate the impact of the different techniques of unprotected left main coronary artery (ULMCA) stenting on the clinical outcomes.

Methods: The study included 65 patients with ACS and left main disease subjected to UPLMCA intervention [46 males (70.8%) with median(Q1-Q3) age of 63(53-70) years old] in an observational prospective cohort study. Data were collected through reviewing patient’s medical records and angiographic procedures. Angiographic assessment included evaluation of Syntax II score, EURO II score, and TIMI flow grading. The primary outcome was the major adverse cardiac and cerebral events (MACCE) at 1 year while the secondary outcomes included the development of acute kidney injury (AKI), one year mortality, and need for CABG post PCI.

Results: One-year MACCE was 46.2 % when the angle between LAD and LCX was>70o compared to 81.5% when it was less than 70o (P=0.008). The wide angle was also associated with 0% 1-year mortality compared to 18.5% for narrow angle, a difference which is statistically significant (P=0.03). The 1-year MACCE was 35.7% compared to 74.4% when it was not used (P=0.013). When POT was used, the 1-year MACCE was 47.6% compared to 75% when it was not used (P=0.041). None of the other studied parameters including those related to procedure technique was significantly affecting the outcome in our study.

Conclusion: We concluded that the non-use of FKI nor POT together with the lower angulation between LAD and LCX could predict worse clinical outcome at one-year in unprotected left main PCI.
