The purpose of this study is to determine if testing patients for endothelial dysfunction will help identify which patients are more likely at risk to have another heart attack in the future. Study participants will undergo mental stress testing while at the same time being connected to a device that measures endothelial function via the Endopat device. These same participants will also undergo a sleep study via the Watchpat device.

Study Start Date: September 2011
Estimated Study Completion Date: September 2015
Estimated Primary Completion Date: September 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
vascular testing
We are assessing vascular testing in patients presenting with acute coronary syndrome to determine if this type of testing will help identify which patients are more likely at risk to have another heart attack.
Other: EndoPAT testing (non invasive device)
Using the EndoPAT device, we will assess endothelial function.
Other Name: Itamar EndoPAT 2000
Other: WatchPAT testing (non-invasive device)
Using the WATCHPAT device we will assess sleep apnea.
Other Name: Itamar WatchPAT 200
