Insights
Complete revascularization significantly reduces major adverse cardiovascular events, reinfarction, and repeat revascularization in ST elevation myocardial infarction (STEMI) patients with multivessel disease. All-cause mortality showed no significant difference between complete and culprit-only revascularization strategies.
Area of Science:
- Cardiology
- Interventional Cardiology
- Clinical Trials
Background:
- ST-elevation myocardial infarction (STEMI) management typically involves percutaneous coronary intervention (PCI) of the culprit vessel.
- The optimal revascularization strategy for patients with multivessel disease remains uncertain.
- This meta-analysis evaluates complete revascularization versus culprit-vessel-only revascularization in STEMI patients.
Purpose of the Study:
- To assess the efficacy and safety of complete revascularization compared to culprit-vessel-only revascularization in STEMI patients.
- To determine the impact on major adverse cardiovascular events (MACE), mortality, reinfarction, and repeat revascularization.
Main Methods:
- A meta-analysis of randomized controlled trials (RCTs) comparing complete versus culprit-vessel-only revascularization.
- Inclusion of 10 RCTs with 7030 patients (3426 complete revascularization, 3604 culprit-only).
- Statistical analysis using risk ratios (RR) and 95% confidence intervals (CI) for dichotomous outcomes.
Main Results:
- Complete revascularization significantly reduced MACE (10.7% vs 20.1%, RR 0.53; P < 0.0001).
- Complete revascularization lowered the risk of reinfarction (5.0% vs 6.9%, RR 0.69; P < 0.01) and repeat revascularization (4.2% vs 12.7%, RR 0.37; P < 0.0001).
- No significant difference in all-cause mortality was observed between the two strategies (4.6% vs 5.0%, RR 0.89; P = 0.27).
Conclusions:
- Complete revascularization is associated with significant reductions in MACE, reinfarction, and repeat revascularization.
- The findings support complete revascularization as a beneficial strategy in STEMI patients with multivessel disease.
- Further research may clarify the impact on long-term mortality and specific patient subgroups.
Background:
In patients with ST elevation myocardial infarction (STEMI), primary percutaneous coronary intervention (PCI) of the culprit vessel is the preferred treatment option. For patients with multivessel disease, the benefit of revascularization of the non-culprit artery is not well known. This meta-analysis aims to assess the efficacy and safety of complete versus culprit vessel only revascularization.
Methods:
Randomized control trials (RCT) that compared head-to-head complete versus culprit-vessel only revascularization in STEMI patients and reported main outcomes of interest such as mortality, myocardial infarction, and revascularization, were included in this meta-analysis.
Results:
We found ten RCTs satisfying our inclusion criteria. Data was extracted and used to estimate the risk ratio (RR) and 95% confidence interval (CI) for dichotomous variables. Our study included 7030 patients (3426 complete revascularization, and 3604 culprit-only revascularization). Complete revascularization (CR) (both immediate and staged) significantly reduced the risk of MACE compared with culprit only (CO) revascularization (10.7% vs 20.1%, RR 0.53; 95% CI 0.43 to 0.64; P < 0.0001), reinfarction (5.0% vs 6.9%, RR 0.69; 95 CI 0.51 to 0.93; P < 0.01), and revascularization (4.2% vs 12.7%, RR 0.37; 95 CI 0.26 to 0.54; P < 0.0001). Our analysis did not find any significant difference in all-cause mortality between CR and CO (4.6% vs 5.0%, RR 0.89; 95 CI 0.72 to 0.1.10; P = 0.27).
Conclusion:
In conclusion, complete revascularization was associated with a significant reduction in major adverse cardiovascular events, revascularization and reinfarction.
