Prevention of Coronary Heart Disease in Morbidly Obese Patients

Active, not recruiting

• Conditions: Hypertension; Morbid Obesity; Type 2 DM; Obstructive Sleep Apnea; Osteoarthrosis

• Registration Number: NCT00626964
• Lead Sponsor: The Hospital of Vestfold

Brief Summary

The changes in risks of developing coronary heart disease in patients with morbid obesity after different weight loss interventions have not been extensively studied. The primary objective of this study is to investigate whether an intensive lifestyle intervention program in a tertiary care clinic (Spesialsykehuset for Rehabilitering) is comparable with a 7-week low-energy-diet followed by bariatric surgery in decreasing the risk of cardiovascular disease in these patients.

Detailed Description

Patients matching the eligibility criteria were divided into two groups (not randomized). One group underwent a 7 weeks Low-Energy-Diet before bariatric surgery, the other group participated in an intensive lifestyle intervention program for 3 months.

Data on arterial stiffness, body weight, body composition, blood pressure, blood samples, vital parameters are registered in the both groups at baseline, 7 weeks and after 1 year.
