Figure 1: Coronary vascular function in obesity
Percent change in coronary blood flow, coronary vascular resistance and coronary epicardial diameter in response to (A) endothelium-dependent vasodilation with acetylcholine and (B) endothelium-independent vasodilation with sodium nitroprusside. (C) Percent change in coronary blood flow and coronary vascular resistance in response to adenosine. Overweight and obese subjects (BMI ≥ 25 kg/m2) in dark columns and normal weight subjects (BMI < 25kg/m2) in open columns. Results expressed as mean ± SEM. Probability values by student’s t-test.
