Patients suffering from heart failure that has a diminished ejection fraction (HFrEF) The the waist-to-height ratio doesn’t provide any evidence of the existence of an obese-survival paradox, as per an online study published on this week of the European Heart Journal.
Jawad Jawad. Butt M.D., from the University of Glasgow in the United Kingdom, and colleagues evaluated the prognostic significance of anthropometric indices that are more recent with the value of BMI, or body mass index (BMI) for patients suffering from HFrEF.
Researchers discovered the existence of an “obesity-survival paradox,” with the risk of dying being lower for those with a BMI of more than 25 kg/m 2. than those with normal weight. However when adjusted for the other prognostic factors the finding was removed. This paradox wasn’t as apparent with respect to waist-to-height ratios and was eliminated after adjustment (adjusted hazard ratio for all cause mortality: 1.10 (95 percent confidence interval: 0.87 up to 1.39] for quintile 5 and 1). Both waist-to height ratio and BMI indicated that higher levels of adiposity were linked to a higher risk of the main result ( heart failure hospitalization or cardiac death) and hospitalization for heart failure and hospitalization for heart failure. The association was more pronounced for the waist-to-height ratio, and remained following adjustment (e.g. an adjustment of hazard rate for hospitalization due to heart failure, 1.39 [95 percent confidence interval, 1.06 to 1.81] for quintile 5 versus 1. of the waist-to-height ratio).
“Our study shows there is no ‘obesity survival paradox’ when we use better ways of measuring body fat,” coauthors of the study stated in an announcement. “It is indices that do not include weight, such as waist-to-height ratio, that have clarified the true relationship between body fat and patient outcomes in our study, showing that greater adiposity is actually associated with worse not better outcomes.”
