title: In-Hospital Complications of Coronary Artery Bypass Graft Surgery in Patients Older Than 70 Years.
abstract: BACKGROUND
  Cardiovascular diseases contribute to mortality and morbidity in aged individuals. It is crucial to have a clear perception of coronary artery bypass graft (CABG) risks and benefits to make logical decision in aged patients. Unfortunately, cardiovascular disease researches have focused very little on the aged patients. The aim of the present study is to evaluate in-hospital complications in patients older than 70 years old following CABG operation to determine if CABG is preferred or not considering present complications.
  
  
  METHODS
  In a cross sectional study, 500 patients older than 70 years old were randomly selected (70-75 patients for each year) from March 2004 to March 2011. Descriptive statistical methods were used for evaluating the obtained data.
  
  
  RESULTS
  Overall, 70.6% of patients (353 individuals) were male and 29.4% were female (147 individuals). Totally, 107 patients (21.4%) had complications during hospitalization; these complications were statistically significant in male individuals. Complications included Stroke 1.6%, deep vein thrombosis 0.8%, MI 2.4%, repeat surgery 2.80%, bleeding 2.40%, and more than 48 hours mechanical ventilation in 13.4%.
  
  
  CONCLUSIONS
  Need for more than 48 hours mechanical ventilation and bleeding after surgery were the most occurred complications in these patients.
