Brief Summary:
The purpose of this study is to assess the non-invasive, Peripheral Arterial Tonometry (PAT) testing as another way of predicting potential coronary artery blockages in the heart.

Condition or disease
Coronary Artery Disease

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.

Study Type : Observational
Actual Enrollment : 201 participants
Observational Model: Cohort
Time Perspective: Prospective
Official Title: Non-Invasive Peripheral Arterial Tonometry (EndoPAT) Increases Diagnostic Yield of Coronary Artery Disease by Coronary Angiography
Study Start Date : September 2010
Actual Primary Completion Date : April 2012
Actual Study Completion Date : June 2014

Patients having a first time angiogram
Patients who are coming to the Cardiac Cath Lab to have an angiogram for the first time

Primary Outcome Measures :
  1. 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 ]
    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.
