Meta-analysis of immediate complete vs staged complete revascularization in patients with acute coronary syndrome and multivessel disease.

ABSTRACT:

Background

Randomized controlled trials (RCTs) have shown varying results between immediate and staged complete percutaneous coronary intervention (PCI) in patients with acute coronary syndrome (ACS) and multivessel disease (MVD). We conducted a meta-analysis to reconcile the findings.

Methods

Online databases were searched for RCTs comparing immediate vs staged complete PCI in patients presenting with ACS. The outcomes of interest were major adverse cardiovascular events (MACE), all cause death, myocardial infarction (MI), cardiovascular death, stent thrombosis, target vessel revascularization (TVR), cerebrovascular events, bleeding and acute kidney injury (AKI)/contrast induced nephropathy (CIN). Risk ratios (RR) with 95 % confidence intervals (CI) were calculated using the random-effects model.

Results

Nine RCTs with a total of 3637 patients - 1821 in the immediate PCI group and 1816 in the staged PCI group, were included. The mean age was 64 years, 78 % of patients were men and the mean duration of follow up was 1 year. As compared with staged complete PCI, the immediate PCI group was associated with significant reduction of MI (RR 0.53, 95 % CI 0.36-0.77) and TVR (RR 0.69, 95 % CI 0.53-0.90). The risks of all-cause death, cardiovascular death, MACE, cerebrovascular events, stent thrombosis, bleeding and AKI/CIN were similar in the two groups.

Conclusions

In ACS patients selected for complete revascularization strategy, multivessel PCI during the index procedure may be associated with significant reduction in the risk of MI and TVR without harm when compared with a staged PCI strategy.
