Network Meta-Analysis of Percutaneous Intervention-Based Revascularization Strategies for ST-Elevation Myocardial Infarction and Concomitant Multi-Vessel Disease.

ABSTRACT: BACKGROUND:In patients with ST elevation myocardial infarction (STEMI) and concomitant multi-vessel disease (MVD), primary percutaneous coronary intervention (PCI) of the culprit vessel is the preferred reperfusion strategy. However, optimum timing of revascularization for non-culprit artery is unclear. In this Bayesian network meta-analysis (NMA), we compared different PCI-based revascularization strategies in STEMI patients with MVD. METHODS:11 randomized controlled trials (RCTs) were selected using MEDLINE, EMBASE and CENTRAL (Inception to September 2017). For all outcomes, median estimate of odds ratio from posterior distribution with corresponding 95% credible interval was calculated. The Surface under the Cumulative Ranking Curve (SUCRA) metric was used to estimate the relative ranking probability of each intervention. Sensitivity analysis was conducted by excluding the RCTs in which the staged intervention was performed after two weeks of the index procedure or post discharge. RESULTS:In this NMA of 3172 patients, CR-I (instant complete revascularization) was associated with 40% relative risk reduction in all-cause mortality compared with IRA (infarct related artery) [0.60 (0.31-0.89)]. CR-I was superior to CR-S (staged complete revascularization) [0.42 (0.22-0.70)] and IRA [0.50(0.29-0.72)] in reducing the risk of re- infarction. Both CR-I and CR-S significantly reduced the risk of repeat revascularization compared to IRA, whereas the risk of CIN (contrast induced nephropathy) and major bleeding was similar across all interventions. Sensitivity analysis showed, that CR-I was a better strategy compared with CR-S [0.34 (0.12-0.74)] and IRA (0.60 [0.36-0.97]) in reducing all-cause mortality. CONCLUSIONS:In this NMA, CR-I was associated with reduction in all-cause mortality and re- infarction compared with IRA.

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:Preinfarction angina may act as a clinical surrogate of ischemic preconditioning that may reduce infarct size and improve mortality in the setting of thrombolytic therapy for ST-elevation myocardial infarction. However, the benefits of preinfarction angina in the setting of primary percutaneous coronary intervention with stenting is inconclusive because of the greater achievement of infarct artery patency and speed of reperfusion.To identify a homogeneous population, we performed a retrospective analysis of 1031 patients admitted with a first ST-elevation myocardial infarction with ischemic times between 1 and 6 hours who received primary percutaneous coronary intervention. We identified 245 patients who had occluded arteries on presentation, of which 79 patients had documented preinfarction angina defined as chest pain within 24 hours of infarction. Infarct size was measured as the peak creatine kinase level, a metric supported in a subgroup by late enhancement on cardiac magnetic resonance imaging. Patients with preinfarction angina (n=79) had a 50% reduction in infarct size compared with those patients without preinfarction angina (n=166) by both peak creatine kinase (1094±75 IU/L versus 2270±102 IU/L; P<0.0001) and creatine kinase area under curve (18 420±18 941 versus 36 810±21 741 IU/h per liter; P<0.0001) despite having identical ischemic times (185±8 minutes versus 181±5 minutes; P=0.67) and angiographic area at risk (24.1±1.2% versus 25.3±0.9%; P=0.43). There was an absolute 4% improvement in left ventricular ejection fraction before discharge in those patients with preinfarction angina (P<0.02).The occurrence of preinfarction angina is associated with significant myocardial protection in the setting of primary percutaneous coronary intervention with stenting during ST-elevation myocardial infarction. Because preinfarction angina is relatively common, it is important that these patients be identified in clinical trials investigating therapies designed to reduce reperfusion injury and infarct size.
