Currently, gender is not considered in the choice of the revascularization strategy for patients with unprotected left main coronary artery (ULMCA) disease. This study analyzed the effect of gender on the outcomes of percutaneous coronary intervention (PCI) vs coronary artery bypass grafting (CABG) in patients with ULMCA disease. Females who had PCI (n = 328) were compared with females who had CABG (n = 132) and PCI in males (n = 894) was compared with CABG (n = 784). Females with CABG had higher overall hospital mortality and major adverse cardiovascular events (MACE) than females with PCI. Male patients with CABG had higher MACE; however, mortality did not differ between males with CABG vs PCI. In female patients, follow-up mortality was significantly higher in CABG patients, and target lesion revascularization was higher in patients with PCI. Male patients had no difference in mortality and MACE between groups; however, MI was higher with CABG, and congestive heart failure was higher with PCI. In conclusion, women with ULMCA disease treated with PCI could have better survival with lower MACE compared with CABG. These differences were not evident in males treated with either CABG or PCI. PCI could be the preferred revascularization strategy in women with ULMCA disease., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

The optimal stenting strategy for unprotected left main coronary artery (ULMCA) disease remains debated. This retrospective observational study (Gulf Left Main Registry) analyzed the outcomes of 1 vs 2 stents in patients with unprotected left main percutaneous coronary intervention (PCI). Overall, 1222 patients were evaluated; 173 had 1 stent and 1049 had 2 stents. The 2-stent group was older with more comorbidities, higher mean SYNTAX scores, and more distal bifurcation lesions. In the 1-stent group, in-hospital events were significant for major bleeding, and better mean creatinine clearance. At median follow-up of 20 months, the 1-stent group was more likely to have target lesion revascularization (TLR). Total mortality was numerically lower in the 1-stent group (.00% vs 2.10%); however, this was not statistically significant ( P =.068). Our analysis demonstrates the benefits of a 2-stent approach for ULMCA patients with high SYNTAX scores and lesions in both major side branches, while the potential benefit of a 1-stent approach for less complex ULMCA was also observed. Further studies with longer follow-up are needed to definitively demonstrate the optimal approach.
