Zafrir B, et al. - In this study performed on patients receiving cardiac catheterization (n = 11,220; mean age 63 ± 10 years) and grouped based on BMI, researchers evaluated the link between percentage change in BMI, as measured 3-years following cardiac catheterization, and long-term mortality. The level measured closest to the timepoint of 3 years after catheterization was regarded as follow-up BMI. In 46% of the patients, they detected a change in BMI of ± 5%. They also noted a decrease > 5% and an increase of > 5% of BMI in 15.5% and in 38.5%, respectively. Findings revealed a reversed J-shaped pattern for the link between percent change in BMI post-cardiac catheterization and all-cause mortality, with both weight loss and weight gain being related to increased risk. They found higher mortality rates in relation to a reduction in BMI than was a rise in BMI for a comparable degree of percentage change.
