Brief Summary

The purpose of the SMART-EXAM (SMart Angioplasty Research Team-Pragmatic Randomized Trial for Comparing Routine versus As-Needed EXercise or Pharmacologic Stress Testing in Asymptomatic Patients with High-Risk Coronary CalciuM) trial is to compare the major adverse cardiovascular events between routine stress testing and as-needed stress testing in asymptomatic patients with high-risk coronary calcium (Agatston Score ≥ 400) without proven ASCVD.

Outcome Measures

Primary Outcomes (1)

  • Occurrence of major adverse cardiovascular events

    a composite of death from cardiovascular causes, myocardial infarction, unplanned hospitalization leading to an urgent revascularization procedure, or heart failure hospitalization

    up to 4.5 years of median follow-up

Secondary Outcomes (12)

  • cardiovascular death

    up to 4.5 years of median follow-up

  • myocardial infarction

    up to 4.5 years of median follow-up

  • unplanned hospitalization leading to an urgent revascularization procedure

    up to 4.5 years of median follow-up

  • heart failure hospitalization

    up to 4.5 years of median follow-up

  • all-cause death

    up to 4.5 years of median follow-up

  • +7 more secondary outcomes

Study Arms (2)

Routine stress testing

EXPERIMENTAL

In this group, the preselected functional stress testing (exercise electrocardiography, stress echocardiography, nuclear imaging, or stress cardiac magnetic resonance imaging) will be performed within three months (± 2 months) according to the practice pattern of each participating center.

Diagnostic Test: Non-invasive stress test

As-needed stress testing

ACTIVE COMPARATOR

In this group, optimal medical treatment will be performed by current guidelines without further testing. A stress test will be performed only when new symptoms (exertional chest pain or dyspnea) occur that may clinically suggest significant coronary artery disease.

Diagnostic Test: Medical treatment without further testing

Interventions

Nuclear imaging, stress echocardiography, exercise electrocardiography, stress cardiac magnetic resonance imaging

Routine stress testing

Optimal medical treatment for primary prevention.

As-needed stress testing

Eligibility Criteria

Age19 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Subject must be at least 19 years of age. ② Asymptomatic patients with high-risk coronary calcium (Agatston Score ≥ 400)

You may not qualify if:

  • Documentation of objective evidence of inducible ischemia before enrollment
  • Presence of significant coronary artery stenosis (≥ 70% diameter stenosis) confirmed by coronary angiography or coronary computed tomography angiography before enrollment
  • History of coronary revascularization procedure ④ Pregnancy or breast feeding ⑤ Non-cardiac co-morbid conditions are present with life expectancy \<1 year or that may result in protocol non-compliance (per site investigator's medical judgment) ⑥ Unwillingness or inability to comply with the procedures described in this protocol.
