Insights
Immediate complete revascularization (ICR) in STEMI patients with multi-vessel disease reduces unplanned revascularization compared to staged complete revascularization (SCR). Both strategies demonstrate comparable safety and effectiveness for major adverse cardiovascular events.
Area of Science:
- Cardiology
- Interventional Cardiology
- Clinical Trials
Background:
- Recent trials suggest immediate complete revascularization (ICR) may be superior to staged complete revascularization (SCR) in STEMI patients with multi-vessel disease (MVD).
- Concerns exist regarding the detection of procedural myocardial infarction (MI) influencing ICR outcomes.
- Previous meta-analyses lacked STEMI data and included observational studies.
Purpose of the Study:
- To conduct an updated meta-analysis comparing ICR and SCR strategies in STEMI patients with MVD.
- To evaluate the impact of revascularization timing on major adverse cardiovascular events (MACE) and other clinical outcomes.
Main Methods:
- Systematic search of electronic databases up to August 2024 for relevant randomized clinical trials (RCTs).
- Inclusion criteria focused on RCTs in STEMI patients with MVD, assessing complete revascularization timing and MACE endpoints.
- Six RCTs with a total of 2023 patients were included in the final analysis.
Main Results:
- The incidence of MACE was comparable between ICR and SCR strategies [RR 0.86, 95% CI (0.58 to 1.27)].
- No significant differences were observed in non-procedural MI, all-cause death, or cardiovascular death between the two groups.
- A significant 40% reduction in unplanned revascularization was noted with ICR compared to SCR [RR 0.60 (0.40 to 0.89), p = 0.01].
Conclusions:
- Immediate complete revascularization (ICR) significantly reduces unplanned revascularization in STEMI patients with MVD compared to staged complete revascularization (SCR).
- Both ICR and SCR strategies are associated with comparable rates of MACE, death, and non-procedural MI, indicating similar safety profiles.
- The findings support the safety and efficacy of both revascularization strategies for managing acute MI in patients with MVD.
Abstract:
Background: Recent randomized clinical trials (RCTs) of STEMI patients with multi-vessel disease (MVD) reported potential superiority of immediate (ICR) vs. staged complete revascularization (SCR). Inherently, the risk of procedural MI is less likely to be detected in ICR patients, and this may have influenced the results. Recently published meta-analyses encompassed observational studies without including STEMI data from the BioVasc trial. The aim of this meta-analysis was to perform an updated comparison of the two strategies in STEMI patients with MVD. Methods: Electronic databases were searched from their inception till August 2024 to identify RCTs assessing CR timing in STEMI patients with MVD. Only studies with an endpoint involving major adverse cardiovascular events (MACE) were included. Results: Six RCTs totaling 2023 patients were included in the analysis. The median time to staged PCI was 19 days. The incidence of MACE (as defined by each study's protocol) was comparable between the two strategies [RR 0.86, 95% CI (0.58 to 1.27)]. There was also no difference in the risk of non-procedural MI [RR 0.91, 95% CI (0.49-1.67)], death [RR 1.47, 95% CI (0.89-2.44)] and cardiovascular death [RR 1.53, 95% CI (0.79-2.98)]. There was a significant 40% reduction in unplanned revascularization in patients undergoing ICR versus SCR [RR 0.60 (0.40 to 0.89), p = 0.01]. Conclusions: ICR reduced the risk of unplanned revascularization compared to SCR but had a comparable effect on MACE, death, cardiovascular death and non-procedural MI. Both strategies are safe in managing patients with acute MI and MVD.
