Eligibility Criteria

Inclusion

  • All patients who meet inclusion criteria and enroll in the parent PROMISE study will be eligible to participate in PROMISE-SAFER.
  • New or worsening chest pain syndrome or equivalent symptoms suspicious for clinically significant coronary artery disease
  • No prior evaluation for this episode of symptoms
  • Planned non-invasive testing for evaluation of possible coronary artery disease
  • Men age \> 55 and women age ≥65 years
  • If age in men 45 - 54 or women 50 - 64 years, then must have increased probability of CAD due to EITHER:
  • A. Diabetes Mellitus (DM) requiring medical treatment OR Peripheral Arterial Disease (PAD) defined as documented \>50% peripheral arterial stenosis treated medically or invasively OR Cerebrovascular disease (stroke, documented \> 50% carotid stenosis treated medically or invasively)
  • OR
  • B. At least one of the following cardiovascular risk factors:
  • Ongoing tobacco use
  • Hypertension
  • Abnormal ankle-brachial index defined as less than \<0.9
  • Dyslipidemia
  • Serum creatinine \< 1.5 mg/dL within the past 90 days
  • Negative urine/serum pregnancy test for female subjects of child-bearing potential and not breast-feeding

Exclusion

  • Diagnosed or suspected acute coronary syndrome requiring hospitalization or urgent or emergent testing; Elevated troponin or creatinine kinase-MB
  • Hemodynamically or clinically unstable condition (systolic blood pressure \< 90 mmHg, atrial or ventricular arrhythmias, or persistent resting chest pain felt to be ischemic despite adequate therapy)
  • Known coronary artery disease with prior myocardial infarction, percutaneous coronary intervention, coronary artery bypass grafting or any angiographic evidence of coronary artery disease ≥50% lesion in a major epicardial vessel.
  • Any invasive coronary angiography or non-invasive anatomic or functional cardiovascular test for detection of coronary artery disease, including coronary computed tomographic angiography and exercise electrocardiogram, within the previous twelve (12) months.
  • Known significant congenital, valvular (\> moderate) or cardiomyopathic process (hypertrophic cardiomyopathy or reduced systolic left ventricular function (left ventricular ejection fraction ≤ 40%)) which could explain cardiac symptoms.
  • Contraindication to undergoing a coronary computed tomographic angiography, including but not limited to:
  • a. Pregnancy or breastfeeding
  • Life expectancy \< 2 years
  • Unable to provide written informed consent or participate in long-term follow-up
