Exploring Obesity Management in Cardiovascular Disease

CardioNerds (Drs. Richard Ferraro, Gurleen Kaur, and Rupan Bose) discuss the growing epidemic of obesity and dive into the role of its procedural management with Dr. Steve Nissen, Chief Academic Officer at the Cleveland Clinic HVTI and past president of the American College of Cardiology. This is an exciting topic that reflects a major inflection point in cardiovascular care. In this episode, we discuss the importance of addressing obesity in cardiovascular care, as it is a major driver of cardiovascular disease and the progression of associated cardiovascular comorbidities. We look at the role of bariatric surgery and its ability to produce sustained weight loss. Finally, we look into the emerging role of new medical therapies such as GLP1 and GIP agonist medications. Notes were drafted by Dr. Rupan Bose and episode audio was edited by CardioNerds Intern Dr. Atefeh Ghorbanzadeh.

Pearls and Quotes - Procedural Management of Obesity with Dr. Steve Nissen Obesity is associated with adverse cardiovascular outcomes. Returning to a healthy weight can largely prevent the downstream consequences of obesity. Regarding lifestyle modifications, diet alone is insufficient in sustaining prolonged weight loss. It is associated with short-term weight loss, but it is generally necessary to supplement with exercise and activity to ensure sustained weight loss. Bariatric surgery should be considered for patients with BMI ≥40 kg/m2 or BMI ≥35 kg/m2 with obesity-related comorbid conditions who are motivated to lose weight and who have not responded to behavioral treatment with or without pharmacotherapy. New emerging medications, including GLP1 receptor agonists, GIP receptor agonists, and glucagon receptor agonists, are beginning to approach weight loss levels that were previously only seen with bariatric surgery. Further research in this dynamic area is ongoing. Show notes - Procedural Management of Obesity with Dr. Steve Nissen Notes drafted by Dr. Rupan Bose. What is the role of obesity in the burden of cardiovascular disease, and why is it so important for CardioNerds to address it? According to the AHA, approximately 2.8 to 3.5 billion people worldwide are either overweight or obese. It is estimated that by 2030, 30% of people in the US will have a BMI greater than 30. Adipose tissue is associated with cytokine release. Cytokines, in turn, can activate and increase levels of IL-1 beta, IL-6, and CRP, leading to an increased inflammatory state. This pro-inflammatory state then accelerates the rate of cardiovascular disease. Obesity is also associated with significant joint and orthopedic diseases, which further impact patients’ quality of life and morbidity. Additionally, obesity is associated with NASH cirrhosis. These adverse liver outcomes hold additional significant systemic implications and morbidity. How do you determine one’s goal weight and goal BMI? Is BMI a good standard for measuring obesity? BMI is a variable of both weight and height. However, it cannot differentiate those whose weight is from adipose tissue versus from muscle mass. Therefore, BMI measurements can sometimes be misleading. Waist circumference may be a better measurement standard for obesity and risk assessment. The “apple shape” body type, with more abdominal fat, is associated with higher inflammation and cardiovascular risk than the “pear-shaped” body type, which is where there is more fat deposition in the buttocks a...
