Is there a difference between immediate and staged surgery for STEMI with multivessel disease?
When a person has a STEMI (a severe heart attack) and also has blockages in more than one coronary artery (multivessel disease), doctors must decide whether to fix all blockages during the same procedure (immediate) or to fix only the culprit blockage first and treat the others later (staged). Research shows that for most patients, the two approaches lead to similar rates of death, heart attacks, and repeat procedures. However, for patients who also have heart failure or cardiogenic shock, staged revascularization appears to be safer.
What the research says
A meta-analysis of 11 randomized controlled trials involving 4,472 patients with STEMI and multivessel disease found no significant difference between immediate and staged complete revascularization for major adverse cardiovascular events, all-cause mortality, cardiovascular mortality, recurrent heart attack, unplanned revascularization, or stent thrombosis 1. The BIOVASC trial, which included both STEMI and non-STEMI patients, also found that immediate revascularization was non-inferior to staged revascularization for the composite of death, heart attack, or unplanned revascularization at 1 year 5.
However, the OPTION-STEMI trial, which focused specifically on STEMI patients, found that immediate revascularization was not non-inferior to staged revascularization for the primary composite endpoint 7. In a subgroup analysis of OPTION-STEMI, patients with heart failure at admission (Killip class II or III) had a higher risk of the primary endpoint with immediate revascularization compared to staged revascularization 4. Similarly, the CULPRIT-SHOCK trial, which studied patients with acute myocardial infarction and cardiogenic shock, found that culprit-lesion-only PCI with staged revascularization led to a lower risk of death or severe renal failure at 30 days compared to immediate multivessel PCI 6.
It is important to note that the meta-analysis included trials with varying definitions of immediate and staged, and some trials used physiology-guided PCI (like fractional flow reserve) to decide which non-culprit lesions to treat 1. The evidence suggests that for stable STEMI patients without shock or heart failure, either strategy is reasonable, but for higher-risk patients, a staged approach may be better.
What to ask your doctor
- Given my specific heart function and overall health, would immediate or staged revascularization be better for me?
- Do I have any signs of heart failure or cardiogenic shock that might make staged revascularization safer?
- What are the risks and benefits of each approach in my case, including the chance of needing another procedure later?
- Will you use fractional flow reserve or other imaging to decide which non-culprit blockages need treatment?
- How long would the delay be between procedures if we choose staged revascularization?
