| Brief Summary | The purpose of this study is to identify and characterize specific chemicals and metabolic pathways that change with forearm ischemia. These changes will be compared with forearm blood flow and flow-mediated vasodilation of the brachial artery. | |||

| Condition ICMJE | Type 2 Diabetes Mellitus | |||
| Intervention ICMJE | Procedure: blood sampling and brachial artery ultrasound
Intravenous blood sampling will be performed before and 15 seconds, 30 seconds, 1,2,5,10,and 30 minutes following an ischemic stimulus (inflation of a blood pressure cuff to suprasystolic pressure for 5 minutes) Brachial artery ultrasound imaging will be performed before and 1 minute after a 5 minute ischemic stimulus, to assess endothelium-dependent vasodilation of the brachial artery. Following completion of blood sampling, an additional "resting" image of the brachial artery will be obtained. Sub-lingual nitroglycerin will be administered, and the artery will be imaged again after 3 minutes, to assess endothelium-independent vasodilation. |
