Gastric band reduces heart attack risk

Heart graph stethoscope

Patients undergoing laparoscopic adjustable gastric banding (LAGB) not only have significant weight loss, but also have major reductions in heart attack risk within a year of surgery according to a recent study. 

The authors selected a group of people aged between 30 and 75 years from a large US healthcare database who had had a laparoscopic adjustable gastric band (LAGB) between January 1st 2005 and April 30th 2010. In all, 647 LAGB patients were included and compared with a group of 4,295 patients who did not have gastric banding. The researchers set out to examine whether weight loss in obese patients treated with LAGB is associated with meaningful reductions in estimated 10- and 30- year heart attack risk, 12–15 months post-LAGB. The average age of the band patients was 45.6 years and 81.1% were female. Measures included blood pressure, diabetes and smoking status.

Outcomes showed that at 12-15 months after surgery the average body mass index (BMI) decreased from 42.7 to 33.4kg/m2, with 35.4% no longer obese*. Estimated 10-year heart attack risk fell by almost 30% (29.6%) in the gastric band group compared with the non-banded group, whilst the 30-year risk fell by 27%.

These findings show that the gastric band results in both significant weight loss* and major reductions in heart attack risk within 12-15 months of surgery.
