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.

Condition Intervention
Acute Coronary Syndrome
Other: EndoPAT testing (non invasive device)
Other: WatchPAT testing (non-invasive device)

Official Title: The Assessment of Novel Functional Risk Factors for the Prediction of Cardiovascular Events in Vulnerable Patients Following Acute Coronary Syndrome

Further study details as provided by Mayo Clinic:

Primary Outcome Measures:
  • Unstable Angina, Myocardial Infarction, Repeat Revascularization, Cardiac Death, Stroke [ Time Frame: Will determine with statistical analysis after all patients have had 2 year follow-up ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Quality of Life [ Time Frame: 6 months post revascularization. ] [ Designated as safety issue: No ]
    Quality of Life as assessed by SF12

Enrollment: 101
Study Start Date: September 2011
Study Completion Date: April 2015
Primary Completion Date: March 2015 (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
