Time Stamps:

00:00 FDG = Fluorodeoxyglucose

00:30 Reduced glucose uptake in the heart is tethered to atherosclerosis.

01:20 LDL levels are not strongly associated with poor outcomes.

02:00 Your heart becomes insulin resistant.

03:05 Those with no glucose uptake in the heart had higher fasting glucose.

03:45 Those with more cardiovascular risk factors had lower LDL.

04:35 The heart can generate energy from fatty acids, carbs, and ketones.

05:00 Cardiac abnormalities are associated with metabolic syndrome.

07:00 Insulin resistance changes muscle and heart muscle.

09:16 Insulin resistance is associated with a progressive decrease of myocardial FDG uptake.

09:50 Cardiovascular risk increases with the decline of FDG uptake.

11:30 Your heart loses the ability to pump blood effectively as it loses ability to utilize different energy substrates.

12:40 Support your heart by supporting your metabolism.
