On the heels of the SYNTAX study which evaluated the effectiveness of using stents to treat multiple blockages, a new journal article outlined the appropriateness of both PCI (stenting and angioplasty) and CABG (bypass surgery) has been published.

Here’s an early glimpse of the article’s main points – most of which reinforce guidelines we’ve known since the early 1980’s (but which were questioned during the height of the stent-enthusiasm.)

Perspective: The following are 10 points to remember about this focused update on appropriate use criteria for coronary revascularization:

1. The writing group and technical panel felt that some quantification of coronary artery disease (CAD) burden, either by description or SYNTAX score, could be helpful to clinicians. Coronary artery bypass grafting (CABG) was rated as appropriate in all of the new clinical scenarios developed, whereas percutaneous coronary intervention (PCI) was rated as appropriate only in patients with two-vessel CAD with involvement of the proximal left anterior descending artery (LAD) and in patients with three-vessel disease with a low CAD burden. [This means that people with a lot of blackages or disease should not receive multiple stents – but should have bypass surgery instead.  The ‘syntax score’ is a rating system used by cardiologists to assign a number to the amount of blockage.  The higher the number, the more blockage.].

2. ST-segment elevation myocardial infarction (STEMI) ≤12 hours from onset of symptoms and revascularization of the culprit artery is rated as appropriate with a score of 9 (on a 1-9 scale). [in the middle of a heart attack, stenting is an appropriate treatment to open the blockage that is causing the heart attack.]

3. Revascularization in patients with one- or two-vessel CAD without involvement of the proximal LAD and no noninvasive testing performed is considered inappropriate.  [This says that You can’t just stent disease that isn’t causing a problem unless the disease is located in critical areas, or just take asymptomatic people to the cath lab.]

4. PCI is considered inappropriate for left main stenosis and additional CAD with intermediate to high CAD burden. [This artery is too important to risk treating with stents.  If this vessel were to have a stent thrombosis – the patient almost always dies.]

5. Revascularization is considered uncertain in unstable angina/NSTEMI and low-risk features (e.g., Thrombolysis in Myocardial Infarction [TIMI] score ≤2) for short-term risk of death or nonfatal MI, but appropriate for those with intermediate-risk features (e.g., TIMI score 3-4) and for those with high-risk features.

6. Appropriateness for PCI is uncertain for three-vessel CAD with intermediate to high CAD burden (i.e., multiple diffuse lesions, presence of chronic total occlusion, or high SYNTAX score), but CABG is appropriate.  [this means that this is still ‘under discussion.’]

7. PCI for isolated left main stenosis is now graded as uncertain. [see number 4.]

8. For patients with acute MI (STEMI or NSTEMI) and evidence of cardiogenic shock, revascularization of one or more coronary arteries is appropriate.

9. It should be noted that uncertain indications require individual physician judgment and understanding of the patient to better determine the usefulness of revascularization for a particular clinical scenario.  [not all treatments fit all patients].

10. The Appropriate Use Criteria writing group and technical panel favor the collaborative interaction of cardiac surgeons and interventional cardiologists heart team approach regarding revascularization decisions in complex patients or coronary anatomy, as recommended in the PCI guidelines. [We should work together to treat the patient, which kind of works against PCI without surgical backup.]
