“Patients receiving GLP-1 receptor agonist therapy should be informed of potential perioperative risks, which may be influenced by their underlying comorbidities,” Jad J. Lawand, MS, a medical student from the John Sealy School of Medicine at the University of Texas Medical Branch, told Healio.
Lawand and colleagues performed a retrospective study of data from patients who underwent anatomic or reverse TSA between January 2010 and December 2023 with minimum follow-up of 90 days.

Lawand and colleagues analyzed data from 1,259 patients who used GLP-1s at the time of surgery and 1,259 patients who did not use GLP-1 receptor agonists at the time of surgery. Prior to propensity matching, patients who used GLP-1 receptor agonists were more likely to be overweight and have preoperative hypertension, heart failure, diabetes, liver disease, tobacco use and chronic kidney disease.
At 90-day postoperative follow-up, Lawand and colleagues found patients who used GLP-1 receptor agonists had significantly increased rates of deep vein thrombosis (1.6% vs. 0.9%; OR = 3), myocardial infarctions (1.6% vs. 0.9%; OR = 2.8), pneumonia (3.34% vs. 1.5%; OR = 2.25), blood transfusions (7.1% vs. 4.3%; OR = 1.7) and readmissions (8.1% vs. 5.2%; OR = 1.6) compared with patients who did not use GLP-1 receptor agonists. However, they found no significant differences between the groups in rates of stroke, pulmonary embolism, postoperative anemia or kidney failure at 90 days.
At 2-year follow-up, 776 patients in each cohort had complete outcomes. Lawand and colleagues found no significant differences in revision rates between patients who used GLP-1 receptor agonists vs. patients who did not use GLP-1 receptor agonists (3.2% vs. 1.8%; OR = 1.8).
“Further investigation into the perioperative risk assessment and medical optimization of patients utilizing GLP-1 receptor agonists may be warranted,” Lawand and colleagues wrote in the study.
