Study Summary
Sex has a major impact on myocardial metabolism and blood flow. In those without heart failure men's hearts tend to use proportionally more glucose and women's hearts use more fat and have higher blood flow. Obesity is a major risk factor for Heart Failure. In those without heart failure, increasing body mass index is predictive of increased blood flow and fatty acid metabolism in women, but not men. To measure blood flow and metabolism we used radioactive materials and a PET (positron emission Tomography) scan to study the blood flow and substrate metabolism of the heart. Hypotheses: 1) Women with heart failure with reduced ejection fraction (HFrEF) will have higher levels of heart blood flow and fatty acid metabolism and lower glucose metabolism rates than men with HFrEF. A secondary Aim was to test the hypothesis that body mass index (BMI), a measure of obesity, correlated with myocardial blood flow and myocardial metabolism measures in patients with HFrEF.
