Body Mass Index and Outcome After Ventricular Assist Device Placement

摘要: Background The implantation of ventricular assist devices (VAD) is an established treatment for end-stage congestive heart failure. Extremes body mass index (BMI) are associated with decreased survival after cardiac surgery. Many patients failure develop cachexia. In this study the association between BMI and outcomes VAD was investigated. Methods Consecutive (n = 590) who underwent placement 1996 2006 were divided into five groups based on (kg/m2) quintiles ( 35). a multivariate analysis adjusted age, sex, diagnosis, emergency level, type device (left or biventricular device), procedural success (recovery, transplantation, 30-day survival) complications analyzed. best group set as reference category calculation odds ratios. Results both extremes had worst outcomes. in 25 to 29 kg/m2. Underweight similar rates normal weight. Overweight obese did not have survival. Extreme obesity at time showed elevated risk postoperative death. There no significant difference cause Cumulative curves overall patient differences. Conclusions Cardiac cachexia need be exclusion criterion placement. appear benefit from mechanical support. Severely should carefully selected before
