Metaanalysis of Multivessel vs Culprit Artery Only Percutaneous Coronary Intervention in ST Elevation Myocardial Infarction.

ABSTRACT: Background: Primary percutaneous coronary intervention (PCI) is the most frequently used treatment modality for patients presenting with ST elevation myocardial infarction (STEMI). Current professional society guidelines recommend culprit artery only PCI. Recent evidence suggests the potential benefit of multivessel PCI among patients with STEMI that is not complicated by cardiogenic shock. Methods: We systematically searched PubMed, EMBASE, and the Cochrane Central Register of Controlled Trials for clinical studies of patients with STEMI, not complicated by cardiogenic shock, who underwent primary PCI between January 1966 and January 2018. We evaluated all-cause and cardiovascular mortality, reinfarction, and repeat revascularization among patients randomized to a multivessel PCI strategy compared to a culprit artery only PCI strategy. Results: Four randomized clinical trials with a total of 1,044 patients met the inclusion criteria. Five hundred and sixty-six patients underwent multivessel PCI, and 478 patients underwent culprit artery only PCI. Multivessel PCI reduced all the studied endpoints: total death, cardiac death, reinfarction, and repeat revascularization (all P values <0.05). Conclusion: To our knowledge, this is the largest metaanalysis of randomized controlled trials studying multivessel PCI vs culprit artery only PCI in STEMI patients without shock, among whom lesion severity was graded by angiography alone. We found that compared to culprit artery only PCI, the multivessel PCI strategy was beneficial in reducing all-cause and cardiovascular mortality, reinfarction, and the need for repeat revascularization.

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.

Project description:BACKGROUND:Failed myocardial reperfusion is common and prognostically important after acute ST-elevation myocardial infarction (STEMI). The purpose of this study was to investigate coronary flow reserve (CFR), a measure of vasodilator capacity, and the index of microvascular resistance (IMR; mmHg × s) in the culprit artery of STEMI survivors. METHODS:IMR (n = 288) and CFR (n = 283; mean age [SD], 60 [12] years) were measured acutely using guide wire-based thermodilution. Cardiac MRI disclosed left ventricular pathology, function, and volumes at 2 days (n = 281) and 6 months after STEMI (n = 264). All-cause death or first heart failure hospitalization was independently adjudicated (median follow-up 845 days). RESULTS:Myocardial hemorrhage and microvascular obstruction occurred in 89 (42%) and 114 (54%) patients with evaluable T2*-MRI maps. IMR and CFR were associated with microvascular pathology (none vs. microvascular obstruction only vs. microvascular obstruction and myocardial hemorrhage) (median [interquartile range], IMR: 17 [12.0-33.0] vs. 17 [13.0-39.0] vs. 37 [21.0-63.0], P < 0.001; CFR: 1.7 [1.4-2.5] vs. 1.5 [1.1-1.8] vs. 1.4 [1.0-1.8], P < 0.001), whereas thrombolysis in myocardial infarction blush grade was not. IMR was a multivariable associate of changes in left ventricular end-diastolic volume (regression coefficient [95% CI] 0.13 [0.01, 0.24]; P = 0.036), whereas CFR was not (P = 0.160). IMR (5 units) was a multivariable associate of all-cause death or heart failure hospitalization (n = 30 events; hazard ratio [95% CI], 1.09 [1.04, 1.14]; P < 0.001), whereas CFR (P = 0.124) and thrombolysis in myocardial infarction blush grade (P = 0.613) were not. IMR had similar prognostic value for these outcomes as <50% ST-segment resolution on the ECG. CONCLUSIONS:IMR is more closely associated with microvascular pathology, left ventricular remodeling, and health outcomes than the angiogram or CFR. TRIAL REGISTRATION:NCT02072850.

Project description:AimsThere are limited contemporary data on the use of initial fibrinolysis in ST-segment elevation myocardial infarction cardiogenic shock (STEMI-CS). This study sought to compare the outcomes of STEMI-CS receiving initial fibrinolysis vs. primary percutaneous coronary intervention (PPCI).MethodsUsing the National (Nationwide) Inpatient Sample from 2009 to 2017, a comparative effectiveness study of adult (>18 years) STEMI-CS admissions receiving pre-hospital/in-hospital fibrinolysis were compared with those receiving PPCI. Admissions with alternate indications for fibrinolysis and STEMI-CS managed medically or with surgical revascularization (without fibrinolysis) were excluded. Outcomes of interest included in-hospital mortality, development of non-cardiac organ failure, complications, hospital length of stay, hospitalization costs, use of palliative care, and do-not-resuscitate status.ResultsDuring 2009-2017, 5297 and 110 452 admissions received initial fibrinolysis and PPCI, respectively. Compared with those receiving PPCI, the fibrinolysis group was more often non-White, with lower co-morbidity, and admitted on weekends and to small rural hospitals (all P < 0.001). In the fibrinolysis group, 95.3%, 77.4%, and 15.7% received angiography, PCI, and coronary artery bypass grafting, respectively. The fibrinolysis group had higher rates of haemorrhagic complications (13.5% vs. 9.9%; P < 0.001). The fibrinolysis group had comparable all-cause in-hospital mortality [logistic regression analysis: 28.8% vs. 28.5%; propensity-matched analysis: 30.8% vs. 30.3%; adjusted odds ratio 0.97 (95% confidence interval 0.90-1.05); P = 0.50]. The fibrinolysis group had comparable rates of acute organ failure, hospital length of stay, rates of palliative care referrals, do-not-resuscitate status use, and lesser hospitalization costs.ConclusionsThe use of initial fibrinolysis had comparable in-hospital mortality than those receiving PPCI in STEMI-CS in the contemporary era in this large national observational study.

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.
