Non-inferiority [ Time Frame: 12 months ] [ 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.

Clinical Evaluation of the CADence Device in Detection of Coronary Artery Diseases
Pivotal Study of the CADence Device in Detection of Coronary Artery Diseases

This is a multi-center, prospective, non-randomized, double-blinded trial to evaluate the performance of the CADence device in detecting the existence of clinically significant coronary artery disease.

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

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.
