Patients who undergo laparoscopic adjustable gastric band (LAGB) surgery enjoy a significant reduction in long-term cardiovascular risk just one year post-surgery, according to a recent study published in the journal Advances in Therapy. 

The team of researchers behind the study set out to examine whether weight loss in obese patients treated with LAGB surgery was associated with reductions in the estimated 10- and 30- year cardiovascular disease (CVD) risk, 12–15 months after surgery. 

Obese adult patients (with a BMI above 30) treated with lap band surgery were identified through a large US healthcare database, and matched to non-LAGP patients by age and gender. Match criteria also took into account baseline measures for BMI, systolic blood pressure, diabetes, and smoking status. 

The data revealed that the ten- and thirty-year estimated cardiovascular risk decreased from 10.8 to 7.6% and from 44.34 to 32.30% respectively, 12–15 months after LAGB surgery. More importantly, improvements were significantly greater than in non-LAGB patients. 

The researchers concluded that the data showed patients who undergo lap band surgery have significant weight loss, reduced CVD risk factors and reduced estimated CVD risk, further confirming the effectiveness of the LAGB procedure as an option for management of obesity. 

“These results add to the evidence of the cardiovascular benefits of significant weight loss among obese individuals and the potential long-term clinical impact of the LAGB procedure as a therapeutic intervention for obesity,” the researchers wrote. 

The researchers cautioned that larger, long-term studies are needed to determine whether the effects of LAGB on CVD risk factors translates into a reduced incidence of CVD.
