Laparoscopic sleeve gastrectomy reduces the predicted coronary heart disease risk and the vascular age in obese subjects.

Abstract

BACKGROUND:

Obesity is associated with high prevalence of coronary heart disease (CHD) and long term increased cardiovascular morbi-mortality. There are no data regarding the effect of laparoscopic sleeve gastrectomy (LSG) on long-term CHD - risk. It is known that "a man is as old as his arteries" and this concept is illustrated by Framingham coronary risk score, which can predict vascular age.

PURPOSE:

To assess the 10-year CHD risk in patients with obesity, preoperatively, and 6 and 12 months after LSG.

METHODS:

47 consecutive obese subjects (44.7% males, mean age 39.8 years) scheduled for LSG were prospectively studied before and 6 and 12 months after surgery. The 10 years CHD risk and corresponding vascular age were calculated using Framingham risk score.

RESULTS:

The body mass index (BMI) decreased from 44.6 ± 10.6 kg m2 preoperatively to 32.2 ± 6.9 kg m2 and to 29.4 ± 5.4 kg m2 at 6 and 12 months follow-up (both p 0.05). Mean excessive weight loss (EWL) was 67.3 ± 23.7% and 78.3 ± 23.4% at 6 and 12 months postoperatively. At 6 and 12 months after LSG, there was a marked improvment of lipid profile(decrease of total cholesterol, LDL-cholesterol, triglycerides and increase of HDL-cholesterol) and a significant decrease in prevalence of diabetes mellitus, systemic hypertension and smoking. The 10-year CHD risk reduced from 10.1% preoperatively to 3.5% and to 2.2% at 6 and 12 months after surgery (both p 0.05). Patients' mean vascular age was 65.6 years preoperatively and decreased to 45.8 years 6 month spostoperatively (p 0.05) and to 40.7 years one year after LSG (p 0.05 vs. 6 months postoperatively, p=NS vs.chronological age).

CONCLUSIONS:

In obese subjects, CHD risk is significantly reduced early, beginning with 6 months after LSG and is diminished with 80% one year postoperatively. Despite the fact that not all patients had achieved the ideal weight yet,mean vascular age is similar to their chronological age one year after surgery.
