Primary Outcome Measures:
  • To determine if the assessment of endothelial function by non-invasive peripheral arterial tonometry improves diagnostic yield of elective coronary angiography [ Time Frame: same day as the angiogram ] [ Designated as safety issue: No ]
    Will compare the score of the EndoPAT test to the outcome of the angiogram to determine if the score is predictive of coronary artery disease.

Enrollment: 201
Study Start Date: September 2010
Study Completion Date: April 2012
Primary Completion Date: April 2012 (Final data collection date for primary outcome measure)
Patients having a first time angiogram
Patients who are coming to the Cardiac Cath Lab to have an angiogram for the first time

Detailed Description:

We are conducting a 16 minute, non-invasive EndoPAT test on patients coming to our cath lab for a first-time angiogram. The angiogram results will be compared to the EndoPAT results to determine if the EndoPAT test, which generates a score, is successful in predicting who may have blockages in their coronary arteries.
