Metabolic Parameters 3 Months, 9 Months, and 2 Years After Bariatric Surgery
An original cohort of 43 patients were recruited for analysis of anthropometrics, metabolic profile, skeletal muscle biopsy, echocardiogram at baseline, 3 months and 9 months post bariatric surgery. While all 43 patients reportedly completed 3 and 9 month evaluations, only 15 patients completed 24 month evaluations due to 28 patients unwilling to return.
The overarching purpose appears to have been not only evaluation of weightloss, but normalization of metabolic profile over time.

- Change in Weight [ Time Frame: 0 to 9 months ]Change in weight. Negative values represent weight loss.
- Change in Glucose [ Time Frame: 0-9 Months ]Change in glucose. Negative values represent a decrease in glucose levels.
- Change in Tissue Doppler Diastolic Velocity [ Time Frame: 0-9 Months ]Change in tissue doppler diastolic velocity. Negative values indicate a decrease in tissue doppler diastolic velocity.
- Change in Left Ventricular Mass [ Time Frame: 0-9 Months ]Change in left ventricular mass, or myocardium, as measured in centimeters using echocardiography. Negative values represent a decrease in ventricular mass.

Procedures were not part of the trial. Patients already undergoing these clinical procedures agreed to analysis and follow-up for research purposes. All patients had one of two different types of procedures, but outcome analyses did not distinguish between the two procedures.
Procedure: Bariatric surgery
Bariatric surgery was not part of this trial. This was observational trial of persons post-bariatric surger.
