The aim of this study is to determine whether a new vectorcardiogram (VCG) analysis will facilitate the detection of significant coronary disease (CAD) in patients with normal rest 12-leads ECG (NE).

Condition Intervention
Cardiovascular Disease Procedure: Routine coronary angiography

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Retrospective
Official Title: Spacial Relation of QRS-T Vectocardiogram is a Good Predictor of Coronary Disease in Patients With Normal Rest 12-leads ECG

Primary Outcome Measures:
  • Detection of CAD in patients undergoing routine coronary angiography [ Time Frame: One month ]
    Following angiography patients will be categorized as having normal coronary arteries (NC) or coronary disease (CD) if more than 50% lumen diameter narrowing is found in one of the arteries.

Estimated Enrollment: 300
Study Start Date: April 2013
Estimated Study Completion Date: June 2013
Estimated Primary Completion Date: June 2013 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Routine coronary angiography patients Procedure: Routine coronary angiography

Detailed Description:
Patients with NE will undergo coronary angiography for routine indications. Prior to the angiography a computerized simultaneous multi-leads ECG will be recorded and, using a new dedicated algorithm for 3D electrical activity reconstruction, the investigators will plot the horizontal VCG of the whole ECG cycle. Using this new VCG analysis we will determine whether the patients have normal coronary arteries or coronary disease.

Ages Eligible for Study:   18 Years to 80 Years   (Adult, Senior)

Accepts Healthy Volunteers:   No
Sampling Method:   Probability Sample
Study Population
Patients undergoing routine coronary angiography

Inclusion Criteria:
