Does immediate surgery help or hurt STEMI patients with multivessel disease and heart failure?
For patients having a heart attack (STEMI) with blockages in multiple heart arteries, doctors must decide whether to perform surgery or stenting right away or to wait. Research shows that doing the procedure immediately does not significantly reduce the risk of death or repeat heart attacks compared to waiting 1. However, for patients who already have heart failure, immediate treatment is linked to worse outcomes at one year 4.
What the research says
A large review of 11 clinical trials involving over 4,400 patients found no significant difference in major heart events between immediate and staged treatment 1. The study looked at death, repeat heart attacks, and the need for new procedures. Immediate treatment did not lower these risks compared to waiting 1. Safety issues like stroke and bleeding were also similar between the two groups 1.
In patients with heart failure, the results are different. A specific trial called OPTION-STEMI found that immediate complete revascularization was associated with a higher risk of death, repeat heart attack, or unplanned surgery at one year compared to staged treatment 4. This higher risk was seen specifically in the group that had heart failure at the time of admission 4.
Another study looked at how to choose which arteries to fix during bypass surgery using a tool called iFR 2. This study found that using iFR helped keep the new grafts open longer in patients with multivessel disease 2. While this study focused on graft patency rather than immediate vs. staged timing, it highlights that careful selection of which arteries to treat is important for long-term success 2.
What to ask your doctor
- Do I have heart failure at the time of my heart attack, and how does that change the timing of my procedure?
- What are the specific risks of doing the surgery immediately versus waiting a few days?
- How will you decide which of my blocked arteries need to be fixed right away and which can wait?
- What tools or tests will you use to decide if an artery is truly causing my heart problems?
