title: [Is obesity a real risk factor in cardiosurgical procedures?].
abstract: OBJECTIVE
  Obesity is generally presented to be a risk factor in surgical procedures including the cardiac ones. The aim of this work was to conduct a retrospective study comparing surgical results of the cardiosurgical procedures depending on each patient's body mass index data (BMI).
  
  
  METHODS
  All 4266 patients operated by our team during 1998-2002 have been included in the study. The patient subjects were allocated in 5 groups according to their individual BMIs. Preoperative, peroperative and postoperative data of all groups were compared.
  
  
  RESULTS
  There were no significant differences in the preoperative and peroperative data between the groups. The postoperative results showed no statistical differences between the individual groups, indicating a trend towards better results in the groups with higher BMIs. On the contrary, the results of the group with the BMI of less than 20 kg/m2 were the worst, however they were also of no statistical significance.
  
  
  CONCLUSIONS
  The restrospective study did not prove the obesity to be a risk factor in cardiosurgical procedures. On the contrary, it suggested the BMI of less than 20 kg/m2 to be a risk factor.
