title: Evaluation of Percutaneous Coronary Intervention and stenting of Left Main Coronary Artery Stenosis in Tehran's Rajaie and Lavasani Hospitals from 2010 to 2011.
abstract: BACKGROUND
  Data of the results from treatment of unprotected and protected LMCA diseases with PCI and stent implantations in our country were limited. Surgical therapy is considered as an standard care for patients with unprotected LMCA stenosis. This notion is based on some randomized and observational studies performed three decades ago which convincingly showed superiority of CABGs over medical therapy. Moreover, preliminary studies have shown that the use of DES for the treatment of unprotected LMCA diseases is associated with very favorable mid-term outcome, which is highly competitive with that of surgery, especially for ostial lesions.
  
  
  OBJECTIVE
  This study sought to evaluate one year safety and effectiveness of PCI and stenting in LMCA disease.
  
  
  METHODS
  We performed a one year clinical follow-up of any patients with LMCA disease "Protected and Unprotected" who underwent PCI and stenting (n = 40) with BMS (n = 17) or DES (n = 23) in Tehran's Rajaje and Lavasani hospitals from September 2010 to September 2011. The primary end points were all-cause mortality, and MACCE which consisted of the composite of death, MI, stroke, and target vessel revascularization, and the duration of hospitalization change the severity of angina pain and the function class of physical activity.
  
  
  RESULTS
  In the one year follow-up, the adjusted risk of death was 5% and the composite of death, MI, stroke and target vessel revascularization (MACCE) was 22%. In 94.7% the number of patients, the severity of angina pain were decreased, and in 92.5% of patients, the function class of physical activity has been improved. The duration of hospitalization was 4.38 ± 1.63 days which was less than that of CABGs.
  
  
  CONCLUSIONS
  For the treatment of protected and unprotected LMCA diseases, PCI with stent implantation is effective, and leads to decreasing the mortality and the death rate, MI, stroke, the severity of angina pain, and improving the function class of physical activity and tolerance.
