Phase 3

Further study details as provided by University of Texas Southwestern Medical Center:

Primary Outcome Measures:
  • Determine if the cumulative costs over 90-days of providing treatment services are reduced when adding coronary CTA to the standard-of-care (CTA + SOC) in patients with acute chest pain compared to SOC alone. [ Time Frame: 90-days ]

Secondary Outcome Measures:
  • Determine if the rate of hospitalizations, nuclear perfusion scans and interventional cardiac catheterizations will be reduced by adding the coronary CTA to the SOC (CTA + SOC) compared to the SOC alone. [ Time Frame: 90-days ]
  • Compare the rate of death, myocardial infarct (MI), acute coronary syndrome (ACS), and recidivism to the ED over 90-days when adding coronary CTA to the SOC (CTA + SOC) in ED patients with acute chest pain compared to the SOC alone group. [ Time Frame: 90-days ]

Estimated Enrollment: 60

Ages Eligible for Study:   35 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  • patients who complain of typical or atypical chest pain (that is compatible with ischemia during the past 12 hrs);
  • patients a prediction of low to intermediate risk of myocardial infarction and/or complications according to established criteria;
  • patients who have normal or non-diagnostic electrocardiograms;
  • patients who have negative cardiac biomarker including creatine kinase-MB, myoglobin, and/or cardiac troponin I at initial testing; patients who require admission to the hospital by the EP at the time of risk-stratification;
  • patients who require cardiology consultation in the ED 7. patients who are age 35 years or older;
  • patients who are able to hold their breath for ≥ 15 seconds (to obtain a quality static anatomical image, scanning requires at least fifteen seconds of breath holding;
  • patients who have heart rate of < 70 beats per minute before or after the administration of beta-blocker medication

Exclusion Criteria:

  • patients who have a contraindication to iodinated and/ or beta-blocking drugs; patients who have compromised renal function defined as creatinine ≥ 1.2 mg/dl;
  • patients who are pregnant, suspected pregnant or other vulnerable populations e.g., incarcerated patients;
  • patients who have documented CAD by prior invasive coronary angiography or coronary CT angiography and/or patients with coronary artery stents, prior angioplasty, or prior coronary artery bypass grafts (CABG);
  • patients who have had prior cardiac imaging (within the past year) with normal result including invasive coronary angiography, coronary CT angiography, or nuclear stress testing;
  • patients who are unstable; patients who have an electrocardiogram diagnostic of ischemia or myocardial infarction (significant Q waves, ST -segment deviations > 0.5 mm, or T wave inversions);
  • patients in atrial fibrillation or have markedly irregular rhythm 9. patients who have had contrast administration within the past 24hrs;
  • patients without an 18 gauge antecubital intravenous access; patients who have a medical home outside of the UTSWMC/Parkland Medical system.
