Primary Outcome Measures:
  • Non-inferiority [ Time Frame: Study completion ] [ Designated as safety issue: No ]
    Primary endpoints are sensitivity and specificity of the CADence in detecting at least one lesion with ≥70% diameter stenosis anywhere in the pLAD, mLAD pLCx, mLCx, pRCA, mRCA, dRCA and OM1, OM2, and RI if segment diameter >2.5 mm or ≥50% diameter stenosis in the LMAIN coronary arteries.

Estimated Enrollment: 729
Study Start Date: February 2013
Estimated Study Completion Date: October 2015
Estimated Primary Completion Date: October 2015 (Final data collection date for primary outcome measure)

Ages Eligible for Study:   22 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population

All enrolled subjects that received nuclear stress testing and either CT or standard coronary angiography after the CADence evaluation will be included in the analysis.


Subjects clinically indicated for nuclear stress test and who satisfy all the inclusion and exclusion criteria are eligible for participation.

Inclusion criteria:

Age 22 years or older Willing and able to give informed consent Clinical indication for nuclear stress test evaluation Chest pain syndrome

Two or more coronary artery disease risk factors as defined by:

  1. Dyslipidemia: LDL >130 mm/dL or HDL <35 mm/dL or on treatment for dyslipidemia
  2. Hypertension: blood pressure >140 mmHg systolic, >90 mmHg diastolic or on blood pressure altering treatment
  3. Obesity: BMI>28
  4. Current cigarette smoking
  5. Diabetes: Type 1 or 2
  6. Family history: coronary disease in a first or second degree relative

Exclusion criteria:

Body Mass Index (BMI)<18.5 or BMI >40

Known coronary disease as defined as:

Prior bypass surgery or coronary stenting Q-wave infarction on a past EKG (>0.01 sec Q-wave duration in two adjacent leads)

Presence of pacemaker/defibrillator Presence of artificial valve Presence of obvious cyanotic or pre-diagnosed congenital heart defect and coarctation of the aorta Presence murmurs including valve lesions, ventricular septal defects, and AV fistualae.

Presence of moderate or severe valve disease as defined by >1/6 heart murmur on physical diagnosis Left Ventricular Assist Device (LVAD) Presence of scars on the site thorax areas Participation in trial within 30 days prior to collecting CADenceTM data except participation in registry studies Asthma with wheezing Inability to lie flat in the supine position Acute coronary syndrome with elevated cardiac biomarkers (TP>3x upper limit of normal (ULN) or CKMB>3x ULN) Heart Transplant Current cocaine use (within the past 24 hours, as reported by subject) Chronic Obstructive Pulmonary Disease (COPD) Contraindication to CT angiography

  • Renal failure with GFR<50 (angio risk)
  • Iodinated contrast allergy
  • Elevated heart rate which cannot be controlled sufficiently to achieve a good CT angiogram
  • Body weight >350lbs.
  • Sinus rhythm rate greater than 100 beats per minute at screening.
  • Atrial fibrillation with average heart rate of greater than 70 beats per minute on resting screening ECG.
