Impact of bariatric surgery on cardiac structure,function and clinical manifestations in morbid obesity

Obesity results from the excessive accumulation of fat. Risk of premature death is doubled compared to nonobese individuals, and risk of death from cardiovascular disease is increased fivefold. In patients with morbid obesity, a variety of adaptations and alterations in cardiac structure and function occur in the individual, as an excess amount of adipose tissue accumulates. The high long-term failure rate of diet intervention is well acknowledged by the clinician. Surgery for severe obesity has evolved during the last 40 years. Many surgical techniques have been described and abandoned. Nevertheless, numerous different techniques are still in use today. Weight loss has beneficial impacts on functional and structural cardiac status and will be reviewed in this report.
