Abstract

Background

We aimed to investigate the impact of laparoscopic sleeve gastrectomy (LSG) on carotid intima-media thickness (CIMT) & left ventricular dysfunction (LVD) which are the independent predictors of subclinical atherosclerosis.

Methods

To assess the change in CIMT & echocardiographic parameters of left ventricular function & correlate with %EWL 6 months and 12 months after LSG, the mean CIMT of bilateral common carotid arteries were measured at 3 different places & 7 parameters were assessed for left ventricular dysfunction after 6 and 12 months of LSG & correlated with the %EWL.

Results

A total of 30 patients (27(90%) women & 3(10%) men) with the mean age of 38 ± 7.84 were prospectively enrolled. BMI was significantly reduced from 42.66 ± 3.79 to 37.93 ± 3.60 kg/m² at six months to 36 ± 3.34 at 12 months after LSG. CIMT values were significantly decreased at 6 months after surgery from 0.50 ± 0.11 mm to 0.46 ± 0.09 mm (p < 0.01) to 0.39 ± 0.07 (p < 0.05) at 12 months. However, no significant change was observed in the right mean CCA values at 6 months after surgery 0.50 ± 0.11 mm vs 0.47 ± 0.09 mm (p = 0.07) as compared to decrease at 12 months after surgery to 0.40 ± 0.08 (p < 0.05). Left mean CCA values at 6 months changed from 0.50 ± 0.11 to 0.45 ± 0.09 (p < 0.01) and at 12 months after surgery to 0.39 ± 007(p < 0.05). On 2D ECHO, ejection fraction increased at 6 months from 60.80 ± 5.89 to 61.93 ± 4.47 (p < 0.5) to after 12 months at 64.30 ± 4.20 (p < 0.05). Wave deceleration time changed at 6 months from 170 ± 36.80 to 150 ± 28.82 (p < 0.05) to 12 months 139.07 ± 17.98 (p < 0.05). Peak early diastolic mitral annular velocity (e) changed at 6 months from 8.12 ± 1.66 to 7.02 ± 1.76 (p < 0.05) to 12 months 6.33 ± 0.76 (p < 0.05). Inter-ventricular septum thickness (IVSD) changed at 6 months from 0.99 ± 0.14 to 0.91 ± 0.14 (p < 0.05) to 12 months 0.82 ± 0.09 (p < 0.05). Intraventricular relaxation time (IVRT) at 6 months changed from 94.33 ± 21.71 to 84.36 ± 14.85 (p < 0.03) to 12 months after surgery 77.40 ± 10.19 (p < 0.05). Left atrial volume index (LAVI) at 6 months decreased from 38.08 ± 11.23 to 30.93 ± 7.16 (p < 0.01) to 12 months after surgery 25.43 ± 3.65 (p < 0.05). Left ventricular diastolic dysfunction [LVIDD] at 6 months changed from 4.32 ± 0.52 to 4.11 ± 0.52 (p < 0.02) to 3.94 ± 0.26 (p < 0.05) to 3.94 ± 0.26 (p < 0.05) at 12 months after surgery. PwD at 6 and 12 months changed from 1.00 ± 0.19 to 0.87 ± 0.10 (p < 0.01) to 0.82 ± 0.08 (p < 0.05) respectively. LV mass changed in 6 months from 148.37 ± 33.09 to 117 ± 29.90 (p < 0.001) to 12 months at 110.64 ± 20.79 (p < 0.05) and left ventricular mass index [LVMI] changed in 6 months from 70 ± 16.89 to 59.626 ± 15.35 (p < 0.001) reaching a value of 57.53 ± 11.18 (p < 0.05) at 12 months. The mean 10-year risk of death due to CVD calculated was significantly reduced from 5.45 ± 6.6 to 2.8 ± 1.7% at 6 months (p < 0.05). This significant decrease in CVD risk has a positive correlation with the decrease in CIMT over 6 months showing a correlation coefficient of 0.018 with statistically significant analysis (p value < 0.05).

Conclusion

We observed a significant reduction in CIMT & improvement in 2D ECHO parameters at 6 after LSG although no statistically significant change was observed in mean right CIMT & EF at 6 months.
