Impact Of Body Mass Index(BMI) On Early Outcomes After Valve Replacement

ObjectiveBecause the prevalence of obesity, cardio-thoracic surgery will face a growing number of obese patients. WHO will be obese is defined as:An excessive accumulation of body fat, thereby threatening the health of chronic diseases. Obesity is a non-infectious, chronic, systemic inflammatory pathological state, adipose tissue and inflammation of the relationship has been extensive attention. Is well known that obesity is the development of diabetes, hypertension and coronary artery disease risk factors.To determine the impact of body mass index (BMI) on clinical outcomes in patients underwent valve replacement.MethodsA One-way ANOVA retrospective evaluation of complication rates (2007-2008) in valve replacement patients categorized by body mass index (BMI) was conducted. The. patients with BMI<20 were defined as the under-weight group a; the patients with BMI20-24.9 were defined as the normal-weight group b; the patients whose BMI>25 were labeled as the overweight and obese group c. Deep wound infections, nervous, respiratory and gastrointestinal complication,30-day operative motality and intensive care unit time were observed.ResultsCompared with the normal weight group, patients with low weight had significant difference with regard to postoperative bleeding/tamponade.ConclusionsBy and large, valve replacement can be performed without significant increase in 30-day mortality in under-weight, overweight and obese patients. This study demonstrated that abnormal BMI does not increase the risk of death and most complications after valve replacemen. Patients with lower body mass index would be more susceptible to postoperative bleeding/tamponade after valve replacement.
