NCT01743040

Brief Summary

This is a multi-center, prospective, non-randomized, double-blinded trial to evaluate the sensitivity and specificity of the CADence device in detecting the existence of clinically significant coronary artery disease as determined by either standard or CT angiography.

Outcome Measures

Primary Outcomes (1)

  • Sensitivity and Specificity of CADence to Detect Stenosis Relative to SPECT Performance, Using Either CT or Standard Angiogram as the Gold Standard

    The CADence will be considered to have demonstrated effectiveness in detecting the presence of at least one lesion with ≥ 70% diameter stenosis anywhere in the proximal Left anterior Descending (pLAD), mid Left anterior Descending (mLAD), proximal Left Circumflex (pLCx), mid Left Circumflex (mLCx), proximal Right Coronary Artery (pRCA), mid Right Coronary Artery (mRCA), distal Right Coronary Artery (dRCA) and Obtuse Margin 1 (OM1), Obtuse Margin 2 (OM2), and Ramus Intermedius (RI) if segment diameter \>2.5 mm or ≥50% diameter stenosis in the Left Main coronary arteries if sensitivity and specificity are non-inferior within 15 percentage points to a sensitivity of 83% and a specificity of 80%, which is the literature-based Objective Performance Criteria (OPC) for nuclear stress tests.

    No more than 3 weeks between CADence, SPECT and standard or CT angiogram

Study Arms (2)

CADence plus Standard Angiogram

All patients who were indicated for angiogram due to results of SPECT nuclear stress test

Diagnostic Test: CADence

CADence plus CT Angiogram

All patients who were not indicated for angiogram due to results of SPECT nuclear stress test underwent CT angiogram

Diagnostic Test: CADence

Interventions

CADenceDIAGNOSTIC_TEST

Patients with chest pain and two or more coronary risk factors and who were already indicated for nuclear stress test were enrolled in the study. The CADence was performed prior to nuclear stress test. Patients underwent standard angiogram based upon normal clinical judgement. In all other patients a CT angiogram followed. CADence is a handheld equipped with acoustic sensor technology, a patient booklet, remote algorithm and final report.
