BackgroundDuring primary percutaneous coronary intervention (PCI), a concurrent chronic total occlusion (CTO) is found in 10% of patients with ST-elevation myocardial infarction (STEMI). Long-term benefits of CTO-PCI have been suggested; however, randomised data are lacking. Our aim was to determine mid-term and long-term clinical outcome of CTO-PCI versus CTO-No PCI in patients with STEMI with a concurrent CTO.MethodsThe Evaluating Xience and left ventricular function in PCI on occlusiOns afteR STEMI (EXPLORE) was a multicentre randomised trial that included 302 patients with STEMI after successful primary PCI with a concurrent CTO. Patients were randomised to either CTO-PCI or CTO-No PCI. The primary end point of the current study was occurrence of major adverse cardiac events (MACE): cardiac death, coronary artery bypass grafting and MI. Other end points were 1-year left ventricular function (LVF); LV-ejection fraction and LV end-diastolic volume and angina status.ResultsThe median long-term follow-up was 3.9 (2.1–5.0) years. MACE was not significantly different between both arms (13.5% vs 12.3%, HR 1.03, 95% CI 0.54 to 1.98; P=0.93). Cardiac death was more frequent in the CTO-PCI arm (6.0% vs 1.0%, P=0.02) with no difference in all-cause mortality (12.9% vs 6.2%, HR 2.07, 95% CI 0.84 to 5.14; P=0.11). One-year LVF did not differ between both arms. However, there were more patients with freedom of angina in the CTO-PCI arm at 1 year (94% vs 87%, P=0.03).ConclusionsIn this randomised trial involving patients with STEMI with a concurrent CTO, CTO-PCI was not associated with a reduction in long-term MACE compared to CTO-No PCI. One-year LVF was comparable between both treatment arms. The finding that there were more patients with freedom of angina after CTO-PCI at 1-year follow-up needs further investigation.Clinical trial registrationEXPLORE trial number NTR1108 www.trialregister.nl.

Abstract Background Studies comparing the outcome of percutaneous coronary intervention (PCI) along with optimal medical therapy (OMT) versus OMT alone in treatment of chronic total occlusion (CTO) are limited by observational design, variable follow up period, diverse clinical outcome, high drop-out and cross-over rate. Prematurely terminated DECISION CTO trail and the promising result of the most recent EUROCTO trial still left the quest unanswered. Previous metanalysis on the present context were restricted to studies with propensity-matched analysis only and did not incorporate the recent randomized trials. Purpose This study aims to conduct a meta-analysis of published data of observational as well as randomized studies comparing long term outcomes of PCI+OMT versus OMT alone. Methods The present protocol is registered in PROSPERO. PubMed, Embase and Cochrane databases were systematically reviewed. Fourteen studies meeting criteria were included in the meta-analysis. The Cochrane Risk of Bias scale was used to appraise the overall quality of the studies. Revman 5.3 software was used to analyse the data and random-effects model with inverse variance method was undertaken. R packages were used for assessment of bias and metaregression. Results Baseline parameters of both the groups were comparable. Major adverse cardiovascular events (MACE) which comprises of cardiac death, myocardial infarction, stroke, and unplanned revascularization [Figure 1] were significantly lower in the PCI+OMT group. (RR: 0.77; 95% CI: 0.61 to 0.97; P≤0.ehz746.00521; I2=85%). High heterogeneity was partially (14%) explained by age factor. However study design, follow up duration, LVEF, presence of TVD did not attribute significantly to heterogeneity, in isolation or any combination in metregression model. All cause mortality and cardiac death [Figure 2, 3 respectively] were significantly lower in the PCI+OMT group (P=0.29, p=0.63, respectively). Myocardial infarction (P=0.25) and stroke rates (P=0.15) were lower in the PCI+OMT group, however they did not reach statistical significance. Unplanned revascularization (of any vessel) showed a higher trend in the PCI+OMT group, without reaching statistical significance (P=0.46, I2=88%). Conclusion PCI of CTO is rewarded with better long term outcome, in terms of MACE and all-cause mortality but limited to greater unplanned revascularization. Acknowledgement/Funding None

Abstract Background Chronic total occlusion (CTO) in a non-infarct-related artery (IRA) is one of the risk factors for mortality after acute myocardial infarction (AMI). However, there are limited data comparing the long-term outcomes of patients underwent successful percutaneous coronary intervention (s-PCI) with patients having medical therapy (MT) in CTO lesion after AMI PCI. Methods We retrospectively enrolled 330 patients (n=166 in s-PCI group and n=164 in MT group) with CTO in a non-IRA from a total of 4372 patients who underwent PCI after AMI from July 2011 to July 2019 in our center (Figure 1). Propensity matching (119 matched pairs) was used to adjust for baseline differences. Major adverse cardiovascular and cerebrovascular events (MACCEs) on follow-up were defined as the composite of cardiac death, all cause death, myocardial infarction (MI), stroke and any revascularization. Kaplan-Meier analysis were used to evaluate the long-term outcomes between s-PCI and MT group. Results The patients in MT group were older, more likely to be diagnosed as STEMI, had lower eGFR and higher peak troponin T level during AMI compared with s-PCI group. Furthermore, in MT group, the involvement of LAD as IRA (50.6% vs 38.6%, p=0.028) and LCX as CTO vessel (45.1% vs 27.1%, p=0.001) was more frequent than in s-PCI group, and thus the involvement of LAD as CTO vessel was less frequent (28.9% vs 39.8%, p<0.001). During a median follow-up period of 946 days, patients in s-PCI group had significantly lower incidences of cardiac death (3.0% vs 10.4%, p=0.017) and all cause death (5.4% vs 14.0%, p=0.030) when compared with patients in MT group. Moreover, after PSM, patients in s-PCI group still showed lower incidence of cardiac death (2.5% vs 9.2%, p=0.04). The incidence of MI, stroke, revascularization and MACCE showed no significant difference between the two groups both before and after PSM. In multivariate analysis, age (HR 1.06, 95% CI 1.02–1.10, p=0.003) and LVEF<50% (HR 4.71, 95% CI 1.72–12.90, p=0.003) showed significant correlation with long term cardiac death, however, successful CTO PCI showed borderline significance (HR 0.42, 95% CI 0.15–1.16, p=0.095). In subgroup analysis, Kaplan–Meier curve showed s-PCI group had a lower incidence of cardiac death compared with MT in patients with LVEF<50% both before (p=0.011) and after PSM (p=0.045). However, no difference was observed between two groups in patients with LVEF≥50%. Conclusions In our center, s-PCI of CTO in non-IRA after AMI PCI showed better long-term cardiac survival as compared with MT. Moreover, patients with low LVEF may be benefit from CTO PCI in non-IRA.

Abstract Background Up to 24% of acute coronary syndrome patients present with ST-elevation but show complete resolution of ST-elevation and symptoms before revascularization. The current guidelines do not clearly state whether these transient ST-elevation myocardial infarction (TSTEMI) patients should be treated with a ST-elevation myocardial infarction (STEMI)-like or a non-STEMI-like invasive approach. Purpose The aim of the present study is to determine the effect of an immediate versus a delayed invasive strategy on infarct size measured by 4-month cardiac magnetic resonance imaging (CMR) and clinical outcome up to one year. Methods In this multicenter trial, 142 TSTEMI patients were randomized 1:1 to either an immediate or a delayed intervention. CMR was performed at four days and at 4-month follow-up to assess infarct size and myocardial function. Clinical follow-up was performed at four months and one year. Results Both in the immediate (0.4 h) and the delayed invasive group (22.7 h) CMR-derived infarct size at four months was very small and left ventricular function was good. In addition, major adverse cardiac events and all-cause mortality at one year were low and not different between both groups (table 1). CMR and clinical outcomes up to one year Outcome Immediate invasive group (n=70) Delayed invasive group (n=72) p-value Myocardial infarct size (% of LV), median (IQR) 0.4 (0.0–3.5) 0.4 (0.0–2.5) 0.79 LVEF (%), mean ± SD 59.9±5.4 59.3±6.5 0.63 LVEF recovery (%), mean ± SD 2.2±5.4 1.7±5.3 0.66 MVO present, No. (%) 0 (0.0) 1 (1.9) 0.50 MACE (death, reinfarction, target lesion revascularization), No. (%) 3 (4.4) 4 (5.7) 1.00 Death from any cause, No. (%) 0 (0.0) 3 (4.3) 0.24 Reinfarction, No. (%) 2 (3.0) 1 (1.4) 0.62 Target lesion revascularization, No. (%) 2 (3.0) 1 (1.4) 0.62 Definite stent thrombosis, No. (%) 1 (1.5) 1 (1.4) 1.00 Abbreviations: IQR, interquartile range; LV, left ventricle; LVEF, left ventricle ejection fraction; MACE, major adverse cardiac events; MVO, microvascular obstruction; NA, not applicable; SD, standard deviation. Conclusions We demonstrated that patients with TSTEMI have limited infarct size and preserved left ventricular function and that an immediate or delayed approach has no effect on clinical outcome up to one year. Therefore, patients with TSTEMI can be treated with both an immediate or a delayed invasive strategy with similar outcome. These findings extend our current knowledge about the optimal timing of coronary intervention in patients with TSTEMI and complement the guidelines. Acknowledgement/Funding AstraZeneca, Biotronik
