What this trial studies

This study investigates how bariatric surgery affects cardiac function in patients with hypertension, using echocardiography to assess changes. It focuses on patients aged 18-70 with a BMI over 24 who have been treated for hypertension with multiple medications. The study aims to clarify the effects of different types of bariatric surgery, specifically laparoscopic sleeve gastrectomy and Roux-en-Y gastric bypass, on heart structure and function. By understanding these effects, the research seeks to provide insights into the cardiovascular benefits of weight loss surgery.
