Abstract:
Obesity contributes to cardiovascular disease in two ways - directly, as an independent risk factor, and indirectly, through its contribution to comorbidities such as hypertension, diabetes, dyslipidemia. This cascade of multiplicative effects means that early management of obesity is instrumental in risk reduction and prevention of adverse cardiovascular outcomes. The amount and sustainability of weight loss has been extensively studied and stratified by medical versus surgical weight loss. Medical weight loss has historically been inferior by both parameters; however, new therapies targeting glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic peptide (GIP) receptors have demonstrated very promising results independently for both weight loss and cardiovascular disease. In this review, we compare cardiovascular outcomes between bariatric surgical approaches and novel GLP-1/GIP medications. We aim to answer the following question: In this era of new pharmacological weight loss options, does the method of weight loss-surgical or medical-impact cardiovascular risk mitigation, or is the key factor the maintenance of a healthier weight, regardless of the method?

Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
