Brief Summary

Revascularization strategies for ST elevation myocardial infarction (STEMI) study (ASSIST-CMR) will compare the effects of two revascularization strategies \[same sitting multivessel primary PCI (SS-PCI) and culprit vessel only primary PCI (IRA-PCI)\] on myocardial infarct size (MIS) as determined by cardiac magnetic resonance (CMR) imaging in patients presenting with STEMI and multivessel disease (MVD).

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • High risk ST elevation myocardial infarction evidenced by: ≥2 mm ST elevation in 2 anterior or lateral leads; or ≥2 mm ST elevation in 2 inferior coupled with ST depression in 2 contiguous anterior leads for a total ST deviation of ≥8 mm; or New left bundle branch block with at least 1 mm concordant ST elevation.
  • Multivessel CAD as evidenced by ≥1 significant (≥70% by visual assessment or FFR\<0.80 for 50-70% stenosis) stenosis in non-IRA.
  • Successful IRA-PCI with \<10% residual angiographic stenosis and TIMI III flow.
  • Written informed consent.

You may not qualify if:

  • Age ≤ 18 years.
  • Prior coronary artery bypass graft (CABG) surgery.
  • Administration of thrombolytic therapy.
  • Non-IRA stenosis is a chronic total occlusion or located in left main artery.
  • Hemodynamic instability evidenced by BP\<90 mmHg, Killip class ≥2, need for inotropes/vasopressors.
  • Known renal insufficiency (estimated GFR \< 50ml/min).
  • Contraindication to CMR.
