<b><i>Introduction:</i></b> Complete revascularization of ST-elevation myocardial infarction (STEMI) patients with multivessel disease (MVD) has recently shown to reduce risk of adverse cardiovascular events, including cardiovascular death. Optimal timing of revascularization of nonculprit lesions remains controversial. We aimed to measure cardiac outcomes related to duration between primary percutaneous coronary intervention (pPCI) of the culprit lesion and staged PCI (sPCI) of nonculprit lesions. <b><i>Methods:</i></b> From a prospectively collected consecutive registry of 3,002 patients treated for STEMI by pPCI, 1,555 patients with MVD requiring sPCI were identified. Patients were placed into quartiles of duration to sPCI: 0–7 days (Q1), 7–22 days (Q2), 22–42 days (Q3), &#x3e;42 days (Q4), excluding those who had complete revascularization at the index event. Major adverse cardiac events (MACEs) included all-cause mortality, myocardial infarction, target vessel revascularization, and coronary artery bypass surgery. Cox regression and propensity score matching were performed correcting for confounding factors. <b><i>Results:</i></b> The average age at presentation was 65.7 ± 11.5 years. 333 were female (21.4%). Mean time between pPCI and sPCI was 28.3 days (±24.8). Rates of MACE were Q1 - 16.5%, Q2 - 21.2%, Q3 - 25.8%, and Q4 - 30.1% (log-rank &#x3c;0.001). Following regression analysis, sPCI remained an independent risk factor for MACE (hazard ratio [HR] = 1.226 [95% confidence interval {CI}: 1.129–1.331, <i>p</i> &#x3c; 0.001]). There was no association between the time interval up to sPCI with all-cause death (HR = 1.022 [95% CI: 0.925–1.129, <i>p</i> = 0.671]). <b><i>Conclusions:</i></b> Patients with MVD are at increased risk of experiencing MACE after revascularization of nonculprit vessels with increasing time delay between pPCI and sPCI.

Abstract Background Insulin resistance (IR) is considered a pivotal risk factor for cardiometabolic diseases, and the triglyceride–glucose index (TyG index) has emerged as a reliable surrogate marker of IR. Although several recent studies have shown the association of the TyG index with vascular disease, no studies have further investigated the role of the TyG index in acute ST-elevation myocardial infarction (STEMI). The objective of the present study was to evaluate the potential role of the TyG index as a predictor of prognosis in STEMI patients after percutaneous coronary intervention (PCI). Methods The study included 1092 STEMI patients who underwent PCI. The patients were divided into 4 quartiles according to TyG index levels. Clinical characteristics, fasting plasma glucose (FPG), triglycerides (TGs), other biochemical parameters, and the incidence of major adverse cardiovascular and cerebral events (MACCEs) during the follow-up period were recorded. The TyG index was calculated using the following formula: ln[fasting TGs (mg/dL) × FPG (mg/dL)/2]. Results The incidence of MACCEs and all-cause mortality within 30 days, 6 months and 1 year after PCI were higher among STEMI patients with TyG index levels in the highest quartile. The TyG index was significantly associated with an increased risk of MACCEs in STEMI patients within 1 year after PCI, independent of confounding factors, with a value of 1.529 (95% CI 1.001–2.061; P = 0.003) for those in the highest quartile. The area under the curve (AUC) of the TyG index predicting the occurrence of MACCEs in STEMI patients after PCI was 0.685 (95% CI 0.610–0.761; P = 0.001). The results also revealed that Killip class > 1, anaemia, albumin, uric acid, number of stents and left ventricular ejection fraction (LVEF) were independent predictors of MACCEs in STEMI patients after PCI (all P < 0.05). Conclusions This study indicated an association between higher TyG index levels and increased risk of MACCEs in STEMI patients for the first time, and the TyG index might be a valid predictor of clinical outcomes in STEMI patients undergoing PCI.

Aims. We investigate the effect of glycoprotein IIb/IIIa (GP IIb/IIIa) inhibitors on long-term outcomes following percutaneous coronary intervention (PCI) after non-ST elevation myocardial infarction (NSTEMI). Meta-analyses indicate that these agents are associated with improved short-term outcomes. However, many trials were undertaken before the routine use of P2Y12inhibitors. Recent studies yield conflicting results and registry data have suggested that GP IIb/IIIa inhibitors may cause more bleeding than what trials indicate.Methods and Results. This retrospective observational study involves 3047 patients receiving dual-antiplatelet therapy who underwent PCI for NSTEMI. Primary outcome was all-cause mortality. Major adverse cardiac events (MACE) were a secondary outcome. Mean follow-up was 4.6 years. Patients treated with GP IIb/IIIa inhibitors were younger with fewer comorbidities. Although the unadjusted Kaplan-Meier analysis suggested that GP IIb/IIIa inhibitor use was associated with improved outcomes, multivariate analysis (including propensity scoring) showed no benefit for either survival (P=0.136) or MACE (P=0.614). GP IIb/IIIa inhibitor use was associated with an increased risk of major bleeding (P=0.021).Conclusion. Although GP IIb/IIIa inhibitor use appeared to improve outcomes after PCI for NSTEMI, patients who received GP IIb/IIIa inhibitors tended to be at lower risk. After multivariate adjustment we observed no improvement in MACE or survival and an increased risk of major bleeding.

This article reviews optimum therapies for the management of ST-elevation myocardial infarction (STEMI) with primary percutaneous coronary intervention (PCI). Optimum anti-thrombotic therapy includes aspirin, bivalirudin and the new anti-platelet agents prasugrel or ticagrelor. Stent thrombosis (ST) has been a major concern but can be reduced by achieving optimal stent deployment, use of prasugrel or ticagrelor, selective use of drug-eluting stents (DES) and use of new generation DES. Large thrombus burden is often associated poor outcomes. Patients with moderate to large thrombus should be managed with aspiration thrombectomy and patients with giant thrombus should be treated with glycoprotein IIb/IIIa inhibitors and may require rheolytic thrombectomy. The great majority of STEMI patients presenting at non-PCI hospitals can best be managed with transfer for primary PCI even with substantial delays. A small group of patients who present very early, who are at high clinical risk and have long delays to PCI, may best be treated with a pharmaco-invasive strategy.

BACKGROUND Coronary microvascular obstruction /no-reflow(CMVO/NR) is a predictor of long-term mortality in survivors of ST elevation myocardial infarction (STEMI) underwent primary percutaneous coronary intervention (PPCI). OBJECTIVE To identify risk factors of CMVO/NR. METHODS Totally 2384 STEMI patients treated with PPCI were divided into two groups according to thrombolysis in myocardial infarction(TIMI) flow grade:CMVO/NR group(246cases,TIMI 0-2 grade) and control group(2138 cases,TIMI 3 grade). We used univariable and multivariable logistic regression to identify risk factors of CMVO/NR. RESULTS A frequency of CMVO/NR was 10.3%(246/2384). Logistic regression analysis showed that the differences between the two groups in age(unadjusted odds ratios [OR] 1.032; 95% CI, 1.02 to 1.045; adjusted OR 1.032; 95% CI, 1.02 to 1.046 ; P <0.001), periprocedural bradycardia (unadjusted OR 2.357 ; 95% CI, 1.752 to 3.171; adjusted OR1.818; 95% CI, 1.338 to 2.471 ; P <0.001),using thrombus aspirationdevices during operation (unadjusted OR 2.489 ; 95% CI, 1.815 to 3.414; adjusted OR1.835; 95% CI, 1.291 to 2.606 ; P =0.001),neutrophil percentage (unadjusted OR 1.028 ; 95% CI, 1.014 to 1.042; adjusted OR1.022; 95% CI, 1.008 to 1.036 ; P =0.002) , and completely block of culprit vessel (unadjusted OR 2.626; 95% CI, 1.85 to 3.728; adjusted-OR 1.656;95% CI, 1.119 to 2.45; P =0.012) were statistically significant ( P <0. 05). The area under the receiver operating characteristic curve was 0.6896 . CONCLUSIONS Age , periprocedural bradycardia, using thrombus aspirationdevices during operation, neutrophil percentage ,and completely block of culprit vessel may be independent risk factors for predicting CMVO/NR.

Abstract Background In the region of South Limburg, the Netherlands, a shared ST-elevation myocardial infarction (STEMI) networking system (SLIM network) was implemented. During out-of-office hours, two percutaneous coronary intervention (PCI) centres—Maastricht University Medical Centre and Zuyderland Medical Centre—are supported by the same interventional cardiologist. The aim of this study was to analyse performance indicators within this network and to compare them with contemporary European Society of Cardiology guidelines. Methods Key time indicators for an all-comer STEMI population were registered by the emergency medical service and the PCI centres. The time measurements showed a non-Gaussian distribution; they are presented as median with 25th and 75th percentiles. Results Between 1 February 2018 and 31 March 2019, a total of 570 STEMI patients were admitted to the participating centres. The total system delay (from emergency call to needle time) was 65 min (53–77), with a prehospital system delay of 40 min (34–47) and a door-to-needle time of 22 min (15–34). Compared with in-office hours, out-of-office hours significantly lengthened system delays (55 (47–66) vs 70 min (62–81), p < 0.001), emergency medical service transport times (29 (24–34) vs 35 min (29–40), p < 0.001) and door-to-needle times (17 (14–26) vs 26 min (18–37), p < 0.001). Conclusions With its effective patient pathway management, the SLIM network was able to meet the quality criteria set by contemporary European revascularisation guidelines.
