Abstract
Background: Major Adverse Cardiac and Cerebrovascular Events (MACCE) include cardiac death, nonfatal Myocardial Infarction (MI), cerebrovascular events, and Target Vessel Revascularization (TVR) that may happen after Percutaneous Coronary Intervention (PCI) or Coronary Artery Bypass Graft (CABG).
Objectives: This study aimed to compare the incidence of MACCE between the patients who underwent PCI or CABG due to significant Left Anterior Descending (LAD) stenosis with and without other coronary arteries involvement.
Patients and Methods: This randomized mixed cohort study was conducted on 400 patients with Coronary Artery Disease (CAD), 200 with proximal LAD stenosis and 200 with non-proximal LAD stenosis, selected through census. Half of each group underwent PCI and the rest underwent CABG. The participants were followed at fixed intervals after the procedure and the incidence of MACCE was documented in their checklists. Then, relative risk index was used to compare the two groups regarding the incidence of MACCE. Statistical analysis was done using the Stata software, version 11 and P < 0.05 was considered to be statistically significant.
Results: The study participants included 281 males and 119 females with the mean age of 61.36 ± 10.66 years. The results showed a significant difference between the two groups regarding the incidence of MACCE (31.58% vs. 3%, P = 0.001). However, no significant difference was found between the effects of PCI with drug eluting stent and CABG on proximal LAD (3.70% vs. 3%, P = 1.00).
Conclusions: Considering the incidence of MACCE, CABG had no superiority over DES for proximal LAD stenosis.
