ObjectiveThe Third Danish Study of Optimal Acute Treatment of Patients with ST-segment Elevation Myocardial Infarction – Ischaemic Postconditioning (DANAMI-3-iPOST) did not show improved clinical outcome in patients with ST-segment elevation myocardial infarction (STEMI) treated with ischaemic postconditioning. However, the use of thrombectomy was frequent and thrombectomy may in itself diminish the effect of ischaemic postconditioning. We evaluated the effect of ischaemic postconditioning in patients included in DANAMI-3-iPOST stratified by the use of thrombectomy.MethodsPatients with STEMI were randomised to conventional primary percutaneous coronary intervention (PCI) or ischaemic postconditioning plus primary PCI. The primary endpoint was a combination of all-cause mortality and hospitalisation for heart failure.ResultsFrom March 2011 until February 2014, 1234 patients were included with a median follow-up period of 35 (interquartile range 28 to 42) months. There was a significant interaction between ischaemic postconditioning and thrombectomy on the primary endpoint (p=0.004). In patients not treated with thrombectomy (n=520), the primary endpoint occurred in 33 patients (10%) who underwent ischaemic postconditioning (n=326) and in 35 patients (18%) who underwent conventional treatment (n=194) (adjusted hazard ratio (HR) 0.55 (95%confidence interval (CI) 0.34 to 0.89), p=0.016). In patients treated with thrombectomy (n=714), there was no significant difference between patients treated with ischaemic postconditioning (n=291) and conventional PCI (n=423) on the primary endpoint (adjusted HR 1.18 (95% CI 0.62 to 2.28), p=0.62).ConclusionsIn this post-hoc study of DANAMI-3-iPOST, ischaemic postconditioning, in addition to primary PCI, was associated with reduced risk of all-cause mortality and hospitalisation for heart failure in patients with STEMI not treated with thrombectomy.Trial registration numberNCT01435408.

AbstractThere is concern whether patients with ST-segment elevation myocardial infarction (STEMI) who admitted to a percutaneous coronary intervention (PCI) center from interhospital transfer is associated with longer reperfusion time compared with direct admission. We evaluated the reperfusion delays in patients with STEMI who admitted to a primary PCI center through interhospital transfer or direct admission. We retrospectively analyzed 6,494 consecutive STEMI patients admitted between 2011 and 2019. Compared with direct admission (n = 4,121; 63%), interhospital transferred patients (n = 2,373) were younger (55 ± 10 vs. 56 ± 10 years, p < 0.001), had similar gender (85.6 vs. 86% male, p = 0.67), greater proportion of off-hour admission (65.2 vs. 48.3%, p < 0.001), less diabetes mellitus (28 vs. 30.8%, p = 0.019), and received more primary PCI (70.5 vs. 48.7%, p < 0.001). Interhospital transferred patients who received primary PCI (n = 3,677) or fibrinolytic (n = 238) had longer symptom-to-PCI center admission time (median, 360 vs. 300 minutes, p < 0.001), shorter door-to-device (DTD) time for primary PCI (median, 74 vs. 87 minutes, p < 0.001), and longer total ischemic time (median, 465 vs. 414 minutes, p < 0.001). Logistic regression in interhospital transferred patients showed that delay in door-in-to-door-out (DI-DO) time at the first hospital was strongly associated with prolonged total ischemic time (adjusted odds ratio = 3.92; 95% confidence interval: 3.06–5.04, p < 0.001). This study suggests that although interhospital transferred patients received more primary PCI with shorter DTD time, interhospital transfer creates longer total ischemic time that associates with the delay in DI-DO time at the first hospital that should be improved.

ObjectiveThe aim of this meta-analysis was to evaluate the effects of ischaemic postconditioning (IPC) therapy on hard clinical endpoints in ST-segment elevation myocardial infarction (STEMI) patients who underwent primary percutaneous coronary intervention (PPCI).DesignSystematic review and meta-analysis to evaluate the effects of IPC on the outcomes of patients with STEMI.Data sourcesPubMed, Embase and the Cochrane Library were systematically searched for relevant articles published prior to May 1, 2018.Eligibility criteria for selecting studiesRandomised trials comparing conventional PPCI to PPCI combined with IPC in STEMI patients were included. The primary endpoint was heart failure. Secondary endpoints were all-cause mortality and major adverse cardiac events (MACE), including cardiac death, heart failure and MI. The Cochrane Reviewer’s Handbook 4.2 was used to assess the risk of bias.Data extraction and synthesisRelevant data were extracted by two independent investigators. We derived pooled risk ratios (RRs) with random effects models. Sensitivity and subgroup analyses were performed.ResultsTen studies that had enrolled 3137 patients were included. PPCI combined with IPC failed to reduce heart failure (RR: 0.88, 95% CI: 0.61 to 1.26, p=0.47; absolute risk: 3.64% in the IPC group and 4.11% in the PPCI only group), all-cause mortality (RR: 0.94, 95% CI: 0.69 to 1.27, p=0.68; absolute risk: 5.07% in the IPC group and 5.27% in the PPCI onlygroup), MACE (RR: 1.05, 95% CI: 0.83 to 1.32, p=0.69; absolute risk: 9.37% in the IPC group and 8.93% in the PPCI only group), cardiac death (RR: 1.28, 95% CI: 0.85 to 1.93, p=0.24; absolute risk: 4.28% in the IPC group and 3.25% in the PPCI only group) and MI (RR: 1.08, 95% CI: 0.38 to 3.12, p=0.88; absolute risk: 3.61% in the IPC group and 3.44% in the PPCI only group).ConclusionsIPC combined with PPCI does not reduce heart failure, MACE and all-cause mortality compared with traditional PPCI in patients with STEMI.Trial registration numberCRD42017063959

Summary Background The China ST-segment elevation myocardial infarction (STEMI) Care Project (CSCAP) was launched in 2011 to address the problems of insufficient reperfusion and long treatment delay in STEMI care in China. Aim To describe the baseline status of STEMI emergency care in Tertiary PCI Hospitals using Phase 1 (CSCAP-1) data. Design CSCAP-1 is a prospective multi-center STEMI registry. Methods and results A total of 4191 patients with symptom onset within 12 or 12–36 h requiring primary percutaneous coronary intervention (PCI), were enrolled from 53 tertiary PCI hospitals in 14 provinces, municipalities, and autonomous regions of China in CSCAP-1. Among them, 49.0% were self-transported to the hospital, 26.5% were transferred to the hospital by calling the emergency medical services directly, and 24.5% were transferred from other hospitals. In patients with symptom onset within 12 h, 83.2% received primary PCI, 5.9% received thrombolysis and 10.9% received conservative medications. The median door-to-balloon time was 115 (85–170) min and the median door-to-needle time for in-hospital thrombolysis was 80 (50–135) min. The overall in-hospital all-cause mortality was 2.4%, while it was 5.3% in the non-reperfusion group and 2.1% in the reperfusion group (P &lt; 0.001). Conclusion Although a long treatment delay and a high proportion of patients transporting themselves to the hospital were observed, trends were positive with greater adoption of primary PCI and lower in-hospital mortality in tertiary hospitals in China. Our results provided important information for further integrated STEMI network construction in China.

Background: Transradial access (TRA) has emerged as the preferred vascular access site for coronary angiography and percutaneous coronary intervention. This systematic review and meta-analysis was performed to evaluate 30-day all-cause mortality comparing TRA with transfemoral access for percutaneous coronary intervention in patients with ST-segment–elevation myocardial infarction. Methods: We performed a systematic literature search and meta-analysis of randomized controlled studies published from inception until January 7, 2020, in MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, and Web of Science Core Collection. Preferred Reported Items for Systematic Reviews and Meta-Analyses guidelines were used for abstracting data. The primary outcome was all-cause mortality at 30 days. Secondary outcomes included myocardial infarction, major bleeding, stroke, and access site complications. Results: A total of 14 studies representing 11 707 patients (5802 patients with TRA; 5905 patients with transfemoral access) were included in this systematic review. All-cause mortality (N=8 studies) was significantly reduced in the TRA group with an overall risk ratio (RR) of 0.72 (95% CI, 0.56–0.92) in the pooled analysis. Major bleeding (N=12 studies; RR, 0.60 [95% CI, 0.45–0.80]) and access site complications (N=9 studies; RR, 0.40 [95% CI, 0.30–0.53]) were significantly higher in the transfemoral access group. There was no statistical difference in reinfarction (N=10 studies; RR, 0.96 [95% CI, 0.75–1.25]) or stroke (N=8 studies; RR, 1.47 [95% CI, 0.87–2.50]). Conclusions: TRA is associated with lower 30-day mortality, major bleeding, and access site complications when compared with transfemoral access in ST-segment–elevation myocardial infarction patients who undergo percutaneous coronary intervention.

Abstract Background Left ventricular (LV) global longitudinal strain has demonstrated incremental prognostic value over LV ejection fraction (LVEF) in patients with ST-segment-elevation acute myocardial infarction. However, LV global longitudinal strain (GLS) does not take into consideration the effect of afterload. Myocardial work (MW) by speckle-tracking echocardiography integrates blood pressure measurements (afterload) with LV GLS and it has been recently demonstrated that Global Work Efficiency (GWE) is associated with long-term all-cause mortality. It remains to be demonstrated if MW indices are associated with hard cardiovascular endpoints. The present study aimed to investigate the prognostic value of global LV MW obtained from pressure-strain loops with echocardiography in patients with ST-segment-elevation myocardial infarction. Methods A total of 100 consecutive ST-segment-elevation myocardial infarction patients (mean age, 61±12 years; 75% men) that survived to discharge were retrospectively analysed. LVEF, GLS and all LVMW indices were measured by transthoracic echocardiography before discharge (4.6±2.0 days after admission). All patients had at least a two-year follow-up (mean follow-up of 833±172 days). Outcomes: all-cause mortality, major acute cardiovascular events (a composite of cardiovascular mortality, myocardial infarction, stroke, unplanned cardiovascular admission) and heart failure hospitalization. Results In the two-year follow-up, 6 patients died, there were 17 patients with MACE, and 3 patients were hospitalized with heart failure. We confirmed that for all-cause mortality, GWE showed higher discrimination, compared to GLS (Table 1), with a cut-off of 83% (log-rank &lt;0,001). For MACE, the performance of all methods is suboptimal, with an AUC &lt;0.65 for all variables, except for GLS. For heart failure admission, performance is slightly better, but GLS is still the better parameter to predict this event. Conclusions LVGWE is a better predictor of all-cause mortality compared to GLS, but MW indices failed to demonstrate a prognostic impact in long-term cardiovascular events. Prospective studies are warranted to confirm this finding. FUNDunding Acknowledgement Type of funding sources: None. Table 1

Aim To investigate the relationship between malnutrition and follow-up cardiovascular (CV) events in non-ST-segment elevation myocardial infarction (NSTEMI).Material and methods A retrospective study was performed on 298 patients with NSTEMI. The baseline geriatric nutritionalrisk index (GNRI) was calculated at the first visit. The patients were divided into three groups accordingto the GNRI: >98, no-risk; 92 to ≤98, low risk; 82 to <92, moderate to high (MTH) risk. The studyendpoint was a composite of follow-up CV events, including all-cause mortality, non-valvular atrialfibrillation (NVAF), hospitalizations, and need for repeat percutaneous coronary intervention (PCI).Results Follow-up data showed that MTH risk group had significantly higher incidence of repeat PCI and all-cause mortality compared to other groups (p<0.001). However, follow-up hospitalizations and NVAFwere similar between groups (p>0.05). The mean GNRI was 84.6 in patients needing repeat PCI and99.8 in patients who did not require repeat PCI (p<0.001). Kaplan Meier survival analysis showed thatpatients with MTH risk had significantly poorer survival (p<0.001). According to multivariate Coxregression analysis, theMTH risk group (hazard ratio=5.372) was associated with increased mortality.Conclusion GNRI value may have a potential role for the prediction of repeat PCI in patients with NSTEMI.
