This article explores the association between preoperative hypercoagulability and myocardial injury in overweight and obese patients undergoing lower limb arthroplasty. The study involved 172 participants and found that around 14% of the participants experienced myocardial injury. However, there was no evidence of a link between baseline hypercoagulability and postoperative troponin elevations. The authors recommend further large-scale studies to validate these findings and determine the clinical value of troponin measurements in perioperative risk stratification for obese patients.
