Complete versus culprit-only revascularization in patients with ST-segment elevation myocardial infarction and multivessel disease: a meta-analysis of randomized trials.

ABSTRACT:

Background

The best strategy for the treatment of the non-infarct artery in patients with ST-elevation myocardial infarction (STEMI) and multivessel disease (MVD) undergoing primary percutaneous coronary intervention (PCI) is not yet defined.

Methods

We searched the literature for randomized controlled trials (RCTs) that compared complete revascularization (CR) with infarct-related coronary artery (IRA) only revascularization in hemodynamically stable patients with STEMI. Random effect risk ratios (RRs) were calculated for clinical outcomes.

Results

Nine RCTs with 2989 patients were included. No significant difference in all-cause mortality emerged between CR and IRA-only groups (relative risk [RR]?=?0.74; 95% confidence interval [CI]: 0.52 to 1.04; p?=?0.08). Compared with IRA-only, CR was associated with significantly lower rates of major adverse cardiac events (MACE) (RR?=?0.53; 95% CI: 0.41 to 0.68; p?ConclusionsFor patients with STEMI and multivessel disease undergoing primary PCI, complete revascularization did not decrease the risk of all-cause mortality in current evidence from randomized trials. When feasible, immediate complete revascularization might be considered in patients with STEMI and multivessel disease.

Project description:BackgroundRecently, several randomized trials have noted improved outcomes with staged percutaneous coronary intervention (PCI) of nonculprit vessels in patients with ST-segment elevation myocardial infarction (STEMI) and multivessel disease. However, it remains unclear whether diabetes status affects the outcomes after different revascularization strategies. This study thus compared the impact of diabetes status on long-term outcomes after staged complete revascularization with that after culprit-only PCI.MethodsFrom January 2006 to December 2015, 371 diabetic patients (staged PCI: 164, culprit-only PCI: 207) and 834 nondiabetic patients (staged PCI: 412, culprit-only PCI: 422) with STEMI and multivessel disease were enrolled. The primary endpoint was 5-year major adverse cardiac and cerebrovascular event (MACCE), defined as a composite of all-cause death, myocardial infarction (MI), stroke or unplanned revascularization.ResultsThe rate of the 5-year composite primary endpoint for diabetic patients was close to that for nondiabetic patients (34.5% vs. 33.7%; adjusted hazard ratio [HR] 1.012, 95% confidence interval [CI] 0.815-1.255). In nondiabetic patients, the 5-year risks of MACCE (31.8% vs. 35.5%; adjusted HR 0.638, 95% CI 0.500-0.816), MI (4.6% vs. 9.2%; adjusted HR 0.358, 95% CI 0.200-0.641), unplanned revascularization (19.9% vs. 24.9%; adjusted HR 0.532, 95% CI 0.393-0.720), and the composite of cardiac death, MI or stroke (11.4% vs. 15.2%; adjusted HR 0.621, 95% CI 0.419-0.921) were significantly lower after staged PCI than after culprit-only PCI. In contrast, no significant difference was found between the two groups with respect to MACCE, MI, unplanned revascularization, and the composite of cardiac death, MI or stroke in diabetic patients. Significant interactions were found between diabetes status and revascularization assignment for the composite of cardiac death, MI or stroke (Pinteraction?=?0.013), MI (Pinteraction?=?0.005), and unplanned revascularization (Pinteraction?=?0.013) at 5 years. In addition, the interaction tended to be significant for the primary endpoint of MACCE (Pinteraction?=?0.053). Moreover, the results of propensity score-matching analysis were concordant with the overall analysis in both diabetic and nondiabetic population.ConclusionsIn patients with STEMI and multivessel disease, diabetes is not an independent predictor of adverse cardiovascular events at 5 years. In nondiabetic patients, an approach of staged complete revascularization is superior to culprit-only PCI, whereas the advantage of staged PCI is attenuated in diabetic patients. Trial registration This study was not registered in an open access database.

Project description:ImportanceRecently, the Complete vs Culprit-Only Revascularization to Treat Multivessel Disease After Early PCI (percutaneous coronary intervention) for STEMI (ST-segment elevation myocardial infarction [MI]) (COMPLETE) trial showed that angiography-guided PCI of the nonculprit lesion with the goal of complete revascularization reduced cardiovascular (CV) death or new MI compared with PCI of the culprit lesion only in STEMI. Whether complete revascularization also reduces CV mortality is uncertain. Moreover, whether the association of complete revascularization with hard clinical outcomes is consistent when fractional flow reserve (FFR)- and angiography-guided strategies are used is unknown.ObjectiveTo determine through a systematic review and meta-analysis (1) whether complete revascularization is associated with decreased CV mortality and (2) whether heterogeneity in the association occurs when FFR- and angiography-guided PCI strategies for nonculprit lesions are performed.Data sourcesA systematic search of MEDLINE, Embase, ISI Web of Science, and CENTRAL (Cochrane Central Register of Controlled Trials) from database inception to September 30, 2019, was performed. Conference proceedings were also reviewed from January 1, 2002, to September 30, 2019.Study selectionEnglish-language randomized clinical trials comparing complete revascularization vs culprit-lesion-only PCI in patients with STEMI and multivessel disease were included.Data extraction and synthesisThe combined odds ratio (OR) was calculated with the random-effects model using the Mantel-Haenszel method (sensitivity with fixed-effects model). Heterogeneity was measured using the I2 statistic. Publication bias was evaluated using the inverted funnel plot approach. Data were analyzed from October 2019 to January 2020.Main outcomes and measuresCardiovascular death and the composite of CV death or new MI.ResultsTen randomized clinical trials involving 7030 unique patients were included. The weighted mean follow-up time was 29.5 months. Complete revascularization was associated with reduced CV death compared with culprit-lesion-only PCI (80 of 3191 [2.5%] vs 106 of 3406 [3.1%]; OR, 0.69 [95% CI, 0.48-0.99]; P = .05; fixed-effects model OR, 0.74 [95% CI, 0.55-0.99]; P = .04). All-cause mortality occurred in 153 of 3426 patients (4.5%) in the complete revascularization group vs 177 of 3604 (4.9%) in the culprit-lesion-only group (OR, 0.84 [95% CI, 0.67-1.05]; P = .13; I2 = 0%). Complete revascularization was associated with a reduced composite of CV death or new MI (192 of 2616 [7.3%] vs 266 of 2586 [10.3%]; OR, 0.69 [95% CI, 0.55-0.87]; P = .001; fixed-effects model OR, 0.69 [95% CI, 0.57-0.84]; P < .001), with no heterogeneity in this outcome when complete revascularization was performed using an FFR-guided strategy (OR, 0.78 [95% CI, 0.43-1.44]) or an angiography-guided strategy (OR, 0.61 [95% CI, 0.38-0.97]; P = .52 for interaction).Conclusions and relevanceIn patients with STEMI and multivessel disease, complete revascularization was associated with a reduction in CV mortality compared with culprit-lesion-only PCI. There was no differential association with treatment between FFR- and angiography-guided strategies on major CV outcomes.
