Abstract P174: Factors Related to Decreased Readmission within 30 Days for Hispanic Heart Failure Patients
Objective: This study was aimed to relate the obesity paradox to readmission and obesity. The obesity paradox remains controversial in the literature. Obesity has detrimental effects on heart failure, but has been found to be paradoxically associated with improved survival. We hypothesized that readmission in heart failure patients is associated with obesity.
Method: We analyzed 732 patients who were admitted for heart failure exacerbation and enrolled in our heart failure program and excluded those who did not follow-up or patients discharged from the cardiology clinic. Patients who were readmitted within 30 days for heart failure exacerbation were investigated. 688 patients who have been followed since 2013 were included. BMI (body mass index) and WC (waist circumference) were classified according to NCEP-ATP III.
Results: The number of normal weight (BMI <25kg/m2), overweight (30 kg/m2>BMI≥25kg/m2) and obesity (BMI≥30kg/m2) were 35.7%, 35.1% and 29.1%, respectively. Central obesity (WC ≥94 cm for men ,and ≥80 for women) were 62%. The number of patients in our selected populations of HFrEF, HFpEF and HFpEF(i) were 456(67.9%),136(20.2%) and 68(11.9%) respectively. A higher readmission rate had a significantly associated with non-obese (BMI less than 30 kg/m2) group compared to obese group(BMI more than 30 kg/m2) in HFpEF patients. There was no significant association between central obesity and readmission. In addition, the absence of diabetes mellitus, an ICD (implantable cardioverter defibrillator), no prior cardiac catheterization and age over 65 were associated with a lower readmission rate.
Conclusion: The obesity paradox with BMI applied to our study group. The obese group had a significant association with reduced readmission rate compared to the normal or overweight BMI group in HFpEF. WC was not associated with readmission. Higher BMI may be related to better cardiopulmonary fitness in HFpEF. To apply to clinical practice, a large randomized study should be warranted. Targeted management in different types of heart failure could be associated readmission.
