Effects of Bariatric Surgery on Cardiovascular Risk Profile in Relation to Inflammatory Parameters: Endothelial Phenotyping and Analysis of the Cross-talk Between Adipose Tissue and Endothelium

Sponsor

Maria Cecilia Hospital

Enrollment

85 participants

Start Date

Study Type

INTERVENTIONAL

Conditions

Obesity (Disorder)

Summary

This research project aims to study how obesity affects the heart and metabolism, and how these effects change after significant weight loss following bariatric surgery. In particular, we want to look at how blood vessels and fat tissue function in people with obesity, to detect early signs of vascular problems and understand how fat tissue communicates with blood vessels. Our main idea is that obesity disrupts the normal function of blood vessels, partly due to substances released by fat tissue and changes in gut bacteria. We believe that 6 and 12 months after surgery - with proper weight loss - these problems will gradually improve. We expect to see better blood vessel function and lower levels of inflammation and fat-related substances in the blood, which could significantly reduce the overall risk of heart disease.

Interventions

OTHERBefore bariatric surgery, both blood and biological samples (stool and urine) will be collected. Patients will also undergo a cardiology examination

This study includes a comprehensive set of laboratory and clinical investigations to evaluate the cardiovascular and metabolic impact of obesity and its modulation after bariatric surgery. Multiple biological samples (blood, urine, stool, and omental adipose tissue) will be collected at baseline and during follow-up.
