Abstract
Reperfusion therapy with percutaneous coronary intervention improves outcomes in patients with ST-elevation myocardial infarction. We conducted a meta-analysis to assess the impact of chronic total occlusion (CTO) in noninfarct-related artery on the outcomes of these patients. Comprehensive searches were performed using PubMed, Google Scholar, and EMBASE. The primary endpoint was the 30-day mortality rate, with secondary endpoints including all-cause mortality, repeat myocardial infarction, and stroke. Forest plots were created for the pooled analysis of the results, with statistical significance set at P < 0.05. A total of 19 studies were included in this meta-analysis, with 23,989 patients (3589 in CTO group and 20,400 in no-CTO group). The presence of CTO was associated with significantly higher odds of 30-day mortality [18.38% vs 5.74%; relative risk (RR), 3.69; 95% confidence intervals (CI), 2.68-5.07; P < 0.00001], all-cause mortality (31.00% vs 13.40%; RR, 2.79; 95% CI, 2.31-3.37; P < 0.00001), cardiovascular-related deaths (12.61% vs 4.1%; RR, 2.61; 95% CI, 1.99-3.44; P < 0.00001), and major adverse cardiovascular events (13.64% vs 9.88%; RR, 2.08; 95% CI, 1.52-2.86; P < 0.00001) than the non-CTO group. No significant differences in repeated myocardial infarction or stroke were observed between the CTO and non-CTO groups. Our findings underscore the need for further research on the benefits and risks of performing staged or simultaneous percutaneous coronary intervention for CTO in the noninfarct-related artery in patients with ST-elevation myocardial infarction.

Abstract
Although a chronic total occlusion (CTO) in the setting of an acute coronary syndrome is associated with greater risk, the prognosis of patients with a CTO and stable coronary artery disease (CAD) remains unknown. This study aimed to investigate adverse event rates in patients with stable CAD with and without a CTO. In 3,597 patients with stable CAD (>50% coronary luminal stenosis) who underwent cardiac catheterization, all-cause mortality, cardiovascular mortality, and the composite major adverse cardiac event (MACE) rates for cardiovascular death, myocardial infarction, and heart failure hospitalization were evaluated. Cox proportional hazards and Fine and Gray subdistribution hazard models were used to compare event-free survival in patient subsets after adjustment for covariates. Event rates were higher in patients with CTOs than in those without CTOs after adjusting for demographic and clinical characteristics (cardiovascular death hazard ratio [HR] 1.29, 95% confidence interval [CI] 1.05 to 1.57, p = 0.012). Patients with CTO revascularization had lower event rates than those of patients without CTO revascularization (cardiovascular death HR 0.43, CI 0.26 to 0.70, p = 0.001). Those with nonrevascularized CTOs were at particularly great risk when compared with those without CTO (cardiovascular death HR 1.52, CI 1.25 to 1.84, p <0.001). Moreover, those with revascularized CTOs had similar event rates to those of patients with CAD without CTOs. Patients with CTO have higher rates of adverse cardiovascular events than those of patients with significant CAD without CTO. This risk is greatest in patients with nonrevascularized CTO.

Abstract
BACKGROUND Out-of-hospital cardiac arrest (OHCA) is the most severe complication of ST-segment elevation myocardial infarction (STEMI). Nevertheless, clinical and angiographic characteristics associated with OHCA among patients with STEMI have not been studied extensively. AIM To evaluate the clinical and angiographic characteristics of consecutive patients who presented with STEMI associated or not with OHCA. METHODS This was an observational study including consecutive patients treated for STEMI associated or not with OHCA. Baseline clinical and angiographic characteristics, biological characteristics and mortality were compared between patients with STEMI who experienced OHCA and patients with STEMI who did not. RESULTS Among the 686 included patients with STEMI, 148 (21.6%) presented with concomitant OHCA. Multivariable analysis revealed that culprit lesion localized on the left system (odds ratio [OR] 1.94, 95% confidence interval [CI] 1.24-3.13; P<0.01), culprit lesion at the level of a bifurcation lesion (OR 1.87, 95% CI 1.21-2.88; P<0.01) and the presence of chronic total occlusion on another artery (OR 3.39, 95% CI 1.93-5.99; P<0.001) were associated with the occurrence of OHCA, whereas dyslipidaemia, familial history of coronary artery disease and hypertension were found to be negatively associated with the occurrence of OHCA in patients with STEMI: OR 0.47, 95% CI 0.29-0.75 (P<0.01); OR 0.09, 95% CI 0.02-0.25 (P<0.001); and OR 0.60, 95% CI 0.38-0.93 (P=0.02), respectively. CONCLUSION In this study of consecutive patients with STEMI, culprit lesion localized on the left system, culprit lesion at the level of a bifurcation lesion and the presence of chronic total occlusion on a non-culprit artery were associated with OHCA.

Abstract
BACKGROUND In ST-segment-elevation myocardial infarction (STEMI), a concomitant chronic total occlusion (CTO) in a non-infarct-related artery (NIRA) is associated with adverse outcome. In the case of the infarct-related artery (IRA) as a donor vessel for collaterals to the CTO, the IRA occlusion may lead to an acute threat to both the immediate IRA and the collaterally supplied CTO area, which has been described as a double-jeopardy effect. METHODS AND RESULTS We investigated the role of preformed intercoronary collaterals to the CTO originating from either the IRA or NIRA. Data were obtained from 2 hospitals participating in the prospective FITT-STEMI (Feedback Intervention and Treatment Times in ST-Segment Elevation Myocardial Infarction) study. From a total cohort of 2102 patients with acute STEMI, 93 patients had single-vessel CTO in an NIRA and well-developed intercoronary collaterals to the CTO. In-hospital mortality differed significantly with respect to the origin of the collaterals. Mortality was 15.2% with collaterals originating from the NIRA, 29.4% with a collateral origin from the IRA proximal to the acute STEMI occlusion, and 3.3% with a collateral origin from the IRA distal to the acute occlusion (P=0.044). A multivariate regression model confirmed that a proximal collateral origin had a significant higher mortality compared with a branching in the distal position from the acute STEMI occlusion (P=0.027; odds ratio = 20.8 [95% CI, 1.4-304.1]). CONCLUSIONS In STEMI with CTO in an NIRA, a CTO collateralization from the IRA distal to the acute occlusion is associated with a better prognosis. This finding challenges the double-jeopardy assumption as the main cause of adverse outcome in STEMI with CTO in an NIRA.

Abstract
OBJECTIVES Co-existing chronic total occlusion (CTO) in a non-infarct-related artery (IRA) might serve as an important trigger of adverse outcomes in ST-segment elevation myocardial infarction (STEMI). Therefore, we planned to analyse the potential impact of non-IRA CTO on the evolution of contrast-associated nephropathy (CAN) in STEMI patients managed with primary percutaneous coronary intervention (P-PCI). METHODS A total of 537 subjects with STEMI undergoing P-PCI during the first 12 h after the onset of their symptoms were enrolled in this retrospective study. The subjects were categorised based on the angiographic presence of non-IRA CTO. Moreover, the subjects were also divided into 2 groups based on their CAN status following P-PCI (CAN (+) and CAN (-)). RESULTS Co-existing non-IRA CTO was demonstrated in 86 subjects (16%). During the hospitalisation period, we identified 81 (15.1%) subjects with CAN. Subjects with non-IRA CTO had a significantly higher incidence of CAN compared with those without (56 [12.4%] vs 25 [29.1%], respectively, p < 0.001). In a logistic regression analysis, an existing non-IRA CTO (odds ratio: 2.840, 95%CI: 1.451-5.558, p = 0.002), as well as age, haemoglobin, diabetes mellitus, creatinine, and white blood cell count, were independent of predictors of CAN. CONCLUSION In STEMI patients managed with P-PCI, a co-existing non-IRA CTO had an independent association with the evolution of CAN.

Abstract
Coronary chronic total occlusion (CTO) contributes to the progression of heart failure in patients with ischemic cardiomyopathy. Randomized controlled trials demonstrated that percutaneous coronary intervention (PCI) for CTO significantly improves angina symptoms and quality of life but fails to reduce clinical events compared with optimal medical therapy. Even so, intervening physicians strongly support CTO-PCI. Cardiac regeneration therapy after CTO-PCI should be a promising approach to improving the prognosis of ischemic cardiomyopathy. However, the relationship between CTO revascularization and cardiac regeneration has rarely been studied, and experimental studies on cardiac regeneration usually employ rodent models with permanent ligation of the coronary artery rather than reopening of the occlusive artery. Limited early-stage clinical trials demonstrated that cell therapy for cardiac regeneration in ischemic cardiomyopathy reduces scar size, reverses cardiac remodeling, and promotes angiogenesis. This review focuses on the status quo of CTO-PCI in ischemic cardiomyopathy and the clinical prospect of cardiac regeneration in this setting.

Abstract
A significant proportion of patients presenting with acute coronary syndromes (ACS) have multivessel disease (MVD). Despite the abundance of clinical trials in this area, several questions regarding the procedure of complete coronary revascularisation remain unanswered. This state-of-the-art review summarises the latest evidence on complete revascularisation (CR) in this subset of patients and critically appraises clinical decision making based on non-culprit lesion (NCL) assessment. Future areas of research are put into perspective.

Abstract
BACKGROUND Sudden cardiac arrest is a serious complication of acute myocardial infarction (MI). Although in-hospital mortality from MI has decreased, the mortality of MI patients complicated with out-of-hospital cardiac arrest (OHCA) remains high. However, the features of acute MI patients with OHCA have not been well known. OBJECTIVES We sought to characterize the clinical and angiographic features of acute MI patients with OHCA comparing with those without OHCA. METHODS We retrospectively analyzed 480 consecutive patients with acute MI undergoing percutaneous coronary intervention. Patients complicated with OHCA were compared with patients without OHCA. RESULTS Of the patients, 141 (29%) were complicated with OHCA. Multivariate analysis revealed that age (odds ratio [OR]: 0.8; 95% confidence interval [CI]: 0.7 to 0.9 per 5 years; p < 0.001), estimated glomerular filtration rate (OR: 0.8; 95% CI: 0.7 to 0.8 per 10 ml/min/1.73 m2; p < 0.001), peak creatine kinase-myocardial band (OR: 1.3; 95% CI: 1.2 to 1.4 per 102 U/l; p < 0.001), calcium-channel antagonists use (OR: 0.4; 95% CI: 0.2 to 0.7; p = 0.002), the culprit lesion at the left main coronary artery (OR: 5.3; 95% CI: 1.9 to 15.1; p = 0.002), and the presence of chronic total occlusion (OR: 2.9; 95% CI: 1.5 to 5.7; p = 0.001) were significantly associated with OHCA. CONCLUSIONS Younger age, no use of calcium-channel antagonists, worse renal function, larger infarct size, culprit lesion in the left main coronary artery, and having chronic total occlusion were associated with OHCA.

Abstract
Coronary chronic total occlusion (CTO) has gained increasing clinical attention as the most advanced form of coronary artery disease. Prior studies already indicated a clear association of CTO with adverse clinical outcomes, especially in patients with acute myocardial infarction (AMI) and concomitant CTO of the non-infarct-related coronary artery (non-IRA). Nevertheless, the prognostic impact of percutaneous coronary intervention (PCI) of CTO in the acute setting during AMI is still controversial. Due to the complexity of the CTO lesion, CTO-PCI leads to an increased risk of complications compared to non-occlusive coronary lesions. Therefore, this review outlines the prognostic impact of CTO-PCI in patients with AMI. In addition, the prognostic impact of periprocedural myocardial infarction caused by CTO-PCI will be discussed.

Abstract
BACKGROUND Chronic total occlusion intervention remains challenging and detailed real-world data on the safety and efficacy of which are limited. This study sought to determine whether there are differences in the 1-year clinical outcomes between chronic total occlusion patients with acute coronary syndrome and stable angina following chronic total occlusion intervention. PATIENTS AND METHODS Data from the Korean chronic total occlusion registry were collected from May 2003 to September 2012, and a total of 3268 patients who underwent chronic total occlusion intervention were enrolled. Cardiovascular outcomes up to 12 months in the acute coronary syndrome group were compared with stable angina group. RESULTS The acute coronary syndrome group consisted of 1657 patients, and stable angina group consisted of 1264 patients. In the acute coronary syndrome group, patients with successful chronic total occlusion intervention had a lower incidence of total death and cardiac death compared to patients with failed intervention. However, there were no significant differences in cardiovascular events in the stable angina group. The successful chronic total occlusion intervention was a significant prognostic factor for lower total death (P = 0.006, hazard ratio = 0.46) and cardiac death (P = 0.003, hazard ratio = 0.36) within acute coronary syndrome group. On the other hand, successful chronic total occlusion intervention was not a prognostic factor for cardiovascular events within stable angina group. CONCLUSIONS Successful chronic total occlusion intervention in acute coronary syndrome patients was associated with a lower incidence of cardiovascular outcome compared to patients with failed chronic total occlusion intervention.

Abstract
Although the presence of chronic total occlusion (CTO) has been associated with long-term mortality in the patients with ST-segment elevation myocardial infarction, the influence of having CTO on in-hospital mortality in sudden cardiac arrest (SCA)-acute coronary syndrome (ACS) patients has not been reported. Therefore, we examined the association between the presence of CTO and in-hospital mortality in those patients. Consecutive 106 SCA-ACS patients who received coronary angiography were retrospectively included. The factors associated with in-hospital mortality were analyzed. Among 106 patients, 40 (38%) patients died during hospitalization. Multivariate analysis revealed presence of CTO dependent on infarct-related artery (IRA-dependent-CTO) (hazard ratio [HR] = 2.88, p = 0.004), diabetes mellitus (HR = 2.04, p = 0.044), percutaneous cardiopulmonary support use (HR = 2.22, p = 0.045), successful recanalization (HR = 0.31, p = 0.004), and peak creatine kinase muscle-brain fraction (HR = 1.11, p < 0.001) were significantly associated with mortality. In conclusion, presence of IRA-dependent-CTO was significantly associated with in-hospital mortality in SCA-ACS patients.

Abstract
`To analyze the impact of additional coronary artery disease, quantified by the SYNTAX (SYNergy between PCI with TAXus and cardiac surgery) score, on left ventricular ejection fraction (LVEF) and long-term outcomes in a cohort of ST-elevated myocardial infarction (STEMI) patients with a concomitant chronic total coronary occlusion (CTO). A total of 302 STEMI patients were randomized to percutaneous coronary intervention of a CTO (CTO PCI) (n = 148) or conservative CTO treatment (n = 154). SYNTAX scores were calculated by an independent corelab (Cardialysis BV, Rotterdam) at two time-points: (1) at baseline, and (2) after primary PCI in the conservative CTO arm and after CTO PCI in the invasive arm (named 'discharge SYNTAX score'). The population was divided in two groups (below or equal to the median SYNTAX score preprimary PCI, or above the median). At 4-month follow-up, the LVEF was significantly lower in patients in the group with a SYNTAX score above the group median (42.8% vs 48.5%, p = 0.001), and the SYNTAX score was an independent predictor for LVEF at 4 months (β-0.151 (SE 0.068), p = 0.028). In the group with a SYNTAX score above the group median the mortality rate was higher (10.1% vs 3.9%, p = 0.025), and there was a trend towards a higher MACE rate (15.4% vs 8.5%, p = 0.063). In conclusion, in this sub-analysis of the EXPLORE trial we observed a worse LVEF and a higher mortality rate for patients with a SYNTAX score above the median. We found that the SYNTAX score is an independent negative predictor for LVEF and an independent positive predictor for LVEDV at 4-month follow-up.

Abstract
AIMS The aim of the current study was to investigate the impact of a chronic total occlusion (CTO) in a non-infarct-related coronary artery (non-IRA) on one-year mortality and occurrence of cardiac arrhythmia in patients with cardiogenic shock (CS) complicating acute myocardial infarction (AMI). METHODS AND RESULTS In a retrospective sub-analysis of the Intraaortic Balloon Pump in Cardiogenic Shock II trial (IABP-SHOCK II) and its accompanying registry, 201 (26%) of 761 patients had a CTO in a non-IR major coronary artery. Mortality was significantly higher in the CTO group at day of admission (19% vs. 11%; p=0.005), 30 days (53% vs. 41%, p=0.002), and 12 months (63% vs. 51%, p=0.002). In the adjusted multivariate Cox regression analysis, a CTO in a non-IRA was an independent predictor of mortality at 12 months (hazard ratio 1.30, 95% confidence interval [CI]: 1.02-1.67, p=0.03). At 30-day follow-up, ventricular arrhythmias requiring defibrillation occurred more frequently in patients with non-IRA CTO in the univariate analysis (33% vs. 21%, odds ratio 1.83, 95% CI: 1.28-2.62, p=0.002). CONCLUSIONS In patients with CS complicating AMI, the presence of CTO in a non-IRA is associated with a higher incidence of ventricular arrhythmias and is an independent predictor of mortality at 12-month follow-up.

Abstract
Chronic total occlusions (CTOs) are commonly encountered in patients undergoing coronary angiography, but percutaneous coronary intervention (PCI) for CTO is currently infrequently performed owing to the perception of limited clinical benefit, high complexity and cost of intervention, and perceived risk of complications. Numerous observational studies have demonstrated that successful CTO revascularization is associated with better cardiovascular outcomes and enhanced quality of life (QOL). However, in the absence of randomized trials, its prognostic benefit remains debated. Nevertheless, over the past decade the interest in CTO-PCI has exponentially grown due to important developments in dedicated equipment and techniques, resulting in high success and low complication rates. A number of factors must be taken into consideration in selecting patients for CTO-PCI, including presence of symptoms attributable to the CTO, extent of ischaemia distal to the occlusion, and degree of myocardial viability. In this review, we focus on the impact of CTO revascularization on clinical outcomes and QOL and on appropriate patient selection. Data regarding efficacy and safety of recent advances in PCI-CTO techniques will be discussed. Steps involved in setting up a dedicated CTO program will be outlined and the current CTO landscape in Belgium will be briefly highlighted. The overall aim of this review is to promote a more balanced approach to management of patients with a CTO.

Abstract
Objective: The presence of chronic total occlusion (CTO) in noninfarct-related artery (non-IRA) is an independent predictor of mortality in acute myocardial infarction (AMI). We investigated whether red cell distribution width (RDW) levels are associated with presence of non-IRA-CTO in AMI (ST-elevation myocardial infarction [STEMI] and non-STEMI). Patients and methods: Patients (n = 858) were categorized into three groups: single vessel disease, multivessel disease (MVD) without CTO and MVD with CTO. Results: MVD with CTO group had higher RDW levels than single vessel disease and MVD without CTO groups (14.87 ± 1.09% vs 13.82 ± 1.01% and 13.87 ± 0.87%, respectively, p < 0.001). In-hospital mortality was also higher in patients with MVD with CTO (p < 0.001). On multivariate analysis, RDW (odds ratio [OR]: 1.761; p < 0.001), age (OR: 1.04; p < 0.001), creatinine (OR: 3.524; p = 0.027), current smoker (OR: 0.489; p = 0.022), hemoglobin (OR: 0.826; p = 0.044), and non-STEMI (OR: 3.065; p < 0.001) were predictors of occurrence of non-IRA-CTO. Conclusion: Increased RDW is independently associated with presence of non-IRA-CTO in AMI patients.

Abstract
BACKGROUND The influence of coexisting collateral circulation between chronic total occlusion (CTO) and infarct-related artery (IRA) in patients with acute ST segment elevation myocardial infarction (STEMI) remains unclear. We aimed to investigate the impact of coexisting collateral circulation between CTO and IRA on early clinical outcomes in patients with acute STEMI. METHODS A total of 1488 consecutive acute STEMI patients who underwent primary percutaneous coronary intervention were prospectively included in the study. After restoration of antegrade flow, the patients who had coexisting CTO and collateral supply from IRA were defined as the CTO-IRA-related (CIR) group (n=56). Patients with coexisting CTO but with no collateral supply from IRA were defined as the CTO-IRA-unrelated (CIUR) group (n=104). Patients without coexisting CTO were defined as the non-CTO group (n=1328). RESULTS Compared with the CIUR and non-CTO groups, the CIR group was significantly associated with higher Killip class of at least 2 (P<0.001) at presentation, a lower rate of postprocedural thrombolysis in myocardial infarction 2/3 flow (P<0.001), and myocardial perfusion grade 3 (P<0.001). Moreover, the CIR group had significantly higher in-hospital (P<0.001) and 30-day mortality (P<0.001). On multivariate regression analysis, the CIR group (odds ratio=15.96, 95% confidence interval=4.94-51.54; P<0.001) as well as age, post-PCI TIMI, Killip and NT-proBNP levels were independently associated with 30-day mortality. However, the CIUR group was not an independent predictor of early clinical outcomes. CONCLUSION After restoration of antegrade flow, coexisting CTO supplied by IRA collaterals has unfavourable effects on procedural success, enzymatic infarct size and postprocedural haemodynamic conditions. These collaterals are also independent predictors of 30-day mortality in acute STEMI patients.

Abstract
Chronic total occlusion (CTO) in a non-infarct-related artery (IRA) is an independent predictor of clinical outcomes in patients with acute myocardial infarction (AMI). This study evaluated the impact of successful percutaneous coronary intervention (PCI) for CTO of a non-IRA on the long-term clinical outcomes in patients with AMI. A total of 4,748 patients with AMI were consecutively enrolled in the Convergent Registry of Catholic and Chonnam University for AMI registry from January 2004 to December 2009. We enrolled 324 patients with CTO in a non-IRA. To adjust for baseline differences, propensity matching (96 matched pairs) was used to compare successful PCI and occluded CTO for the treatment of CTO in non-IRA. The primary clinical end points were all-cause mortality and a composite of the major adverse cardiac events, including cardiac death, MI, stroke, and any revascularization during the 5-year follow-up. Patients who received successful PCI for CTO of non-IRA had lower rates of all-cause mortality (16.7% vs 32.3%, hazard ratio 0.459, 95% CI 0.251 to 0.841, p = 0.012) and major adverse cardiac events (21.9% vs 55.2%, hazard ratio 0.311, 95% CI 0.187 to 0.516, p <0.001) compared with occluded CTO group. Subgroup analyses revealed that successful PCI resulted in a better mortality rate in patients with normal renal function compared to patients with chronic kidney disease (p = 0.010). In conclusion, successful PCI for CTO of non-IRA is associated with improved long-term clinical outcomes in patients with AMI.

Abstract
When patients with ischaemic heart disease are considered for revascularisation the Heart Team's aim is to choose a therapy that will provide complete relief of angina for an acceptable procedural risk. Complete functional revascularisation of ischaemic myocardium is thus the goal and for this reason the presence of a chronic total occlusion (CTO) - which remain the most technically challenging lesions to revascularise percutaneously - is the most common reason for selecting coronary artery bypass surgery. From the behaviour of Heart Teams it is clear that physicians believe that CTOs are important. Yet when faced with patients with CTOs for whom surgery appears excessive (e.g. nonproximal LAD) or too high risk, there remains a reluctance to undertake CTO PCI, despite significant recent advances in procedural success and safety and a considerable body of evidence supporting a survival benefit following successful CTO PCI. This article reviews the relationship between CTOs, symptoms of angina, ischaemia and left ventricular dysfunction and further explores the evidence relating their treatment to improved quality of life and prognosis in patients with these features.

Meta-Analysis of the Impact on Mortality of Noninfarct-Related Artery Coronary Chronic Total Occlusion in Patients Presenting With ST-Segment Elevation Myocardial Infarction. Am J Cardiol 2015; 116:8-14. [PMID: 26068700 DOI: 10.1016/j.amjcard.2015.03.031] [Citation(s) in RCA: 28] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/07/2015] [Revised: 03/24/2015] [Accepted: 03/24/2015] [Indexed: 01/02/2023]
Abstract
Several observational studies have compared clinical outcome in patients with a co-existing noninfarct-related artery chronic total occlusion (n-IRA CTO) versus those without, suggesting increased all-cause mortality. The goal of this study was to provide a systematic review and meta-analysis evaluating the impact of the presence of an n-IRA CTO on short- and long-term mortality after primary percutaneous coronary intervention. Studies published from January 1980 to January 2014 that compared the incidence of all-cause mortality in patients with ST-segment elevation myocardial infarction with co-existing n-IRA CTO versus those without were identified using an electronic search and reviewed using meta-analytical techniques. Seven studies (5 observational studies and 2 observational analyses of randomized controlled trials) comprising 14,117 patients and 1,554 patients (11.7%) with n-IRA CTO were included. The presence of n-IRA CTO was associated with increased incidence of all-cause mortality at a median follow-up of 25.2 months (interquartile range 24 to 60) compared with no CTO (absolute risk 23.5% vs 9.0%; odds ratio [OR] 2.90, 95% confidence interval [CI] 2.09 to 4.01; p <0.0001). This finding was consistent in the analysis of studies reporting 30-day follow-up (absolute risk 17.2% vs 4.7%; OR 3.79, 95% CI 3.13 to 4.59; p <0.0001). Co-existing n-IRA CTO was also associated with increased mortality in a subanalysis of patients with multivessel disease only (absolute risk 24.2% vs 11.3%; OR 2.23, 95% CI 1.90 to 2.63; p <0.0001). In conclusion, coronary CTO in the nonculprit artery in patients presenting with ST-segment elevation myocardial infarction is associated with increased short- and long-term all-cause mortality.

Abstract
Chronic total occlusions (CTOs) of coronary arteries represent a common and significant challenge to interventional cardiology. Medical therapy is often regarded as an adequate long term strategy in the management of these lesions with surgical intervention for refractory symptoms. Extensive collateralisation is used as a marker of distal coronary perfusion, further reinforcing non-invasive strategies. This together with relatively low percutaneous success rates outside of specialised centres has meant that rates of percutaneous intervention have remained low. Increasing evidence suggests that CTOs are not a benign entity. Further, symptom control and quality of life improve significantly with successful percutaneous revascularisation. Both factors have reignited interest in percutaneous modalities. The Japanese have been pioneers in the field of CTO intervention although their success rates have been difficult to replicate. New techniques and equipment developed in North America offer an alternative to the Japanese approach. These techniques focus on time, radiation and contrast minimisation. This review will assess the histopathology of CTO and shifting paradigms in CTO treatment strategies. Chronic total occlusions are common and prognostically important. Strategies for chronic occlusions are pioneered by Japanese, adapted by North American operators. Japanese and North American strategies appear divergent, both add considerable expertise.

Abstract
Coronary chronic total occlusion (CTO) carries a poor outcome in patients with acute myocardial infarction (AMI) treated with primary percutaneous coronary intervention (PCI). We sought to investigate the prognostic impact of a staged successful CTO-PCI in patients with AMI treated with primary PCI. Outcome analysis included consecutive patients treated by successful primary PCI with coexisting non-infarct-related artery CTO who survived after 1 week from AMI. A comparison between patients with successful CTO-PCI and patients with failed or nonattempted CTO-PCI was performed. The primary end points of the study were 1-year and 3-year cardiac survival. Of 1,911 patients who underwent successful primary PCI for AMI from 2003 to 2012, 169 (10%) had non-infarct-related artery CTO of a major branch. A staged CTO-PCI attempt was performed in 74 patients (44%) and was successful in 58 (success rate 78%). All patients with successful CTO-PCI received drug-eluting stents. In the successful CTO-PCI group, a complete coronary revascularization was achieved in 88% of the patients. The 1-year cardiac mortality rate was 1.7% in the successful CTO-PCI group and 12% in nonattempted or failed CTO-PCI group (p = 0.025). Successful CTO-PCI was an independent predictor of 3-year cardiac survival (hazard ratio 0.20, 95% confidence interval 0.05 to 0.92, p = 0.038). In conclusion, successful CTO-PCI in survivors after primary PCI is associated with improved long-term cardiac survival.

Abstract
Objective We investigated the impact of the severity of stenosis in a non-infarct-related artery (IRA) on the long-term prognosis of patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI). Methods Three hundred one consecutive patients (age: 59.7 ± 13.2 years, 85.5% men) underwent primary PCI during 2009–2012. Receiver operating characteristic curve analysis found the optimal cutoff for non-IRA SYNTAX score (SS) to be 2.5. We divided the patients into two groups according to this cutoff value. Results By multivariable analysis, non-IRA SS (≥2.5) was an independent predictor of major adverse cardiac events (hazard ratio [HR]: 2.15, 95% confidence interval [CI]: 1.21–3.79, P = 0.008) and all-cause mortality (HR: 3.49, 95% CI: 1.13–10.8, P = 0.03). However, the prediction of cardiovascular mortality had only borderline significance (HR: 3.29, 95% CI: 0.90–12.08, P = 0.07). Conclusion STEMI patients treated with primary PCI and moderate to severe non-IRA stenosis (SS ≥2.5) have more subsequent cardiac events. Those populations should be treated with more aggressive preventive and medical management.

Abstract
Chronic total occlusion (CTO) in a noninfarct-related artery (non-IRA) is an independent predictor of mortality in acute coronary syndrome (ACS). Mean platelet volume (MPV) and serum uric acid (SUA) are associated with cardiovascular events in ACS. We investigated the relationship between the presence of non-IRA-CTO with MPV and SUA levels in patients with ACS. Patients (n = 1024) who underwent urgent coronary angiography for ACS were included in this study. Blood samples were drawn on admission. Patients were categorized into 2 groups: non-IRA-CTO (−) and non-IRA-CTO (+). The MPV and SUA levels on admission were significantly higher in the non-IRA-CTO (+) group than in the non-IRA-CTO (−) group ( P < .001). At multivariate analysis, MPV (odds ratio [OR]: 4.705, P < .001) and SUA (OR: 2.535, P < .001) were independent predictors of non-IRA-CTO together with age, hemoglobin, ejection fraction, and non-ST-segment elevation ACS. The MPV and SUA levels were significant and independent predictors for the presence of non-IRA-CTO in patients with ACS.

Abstract
Chronic total occlusions (CTOs) are often detected on diagnostic coronary angiograms, but percutaneous coronary intervention (PCI) for CTO is currently infrequently performed owing to high technical difficulty, perceived risk of complications, and a lack of randomized data. However, successful CTO-PCI can significantly increase a patient's quality of life, improve left ventricular function, reduce the need for subsequent CABG surgery, and possibly improve long-term survival. A number of factors must be taken into account for the selection of patients for CTO-PCI, including the extent of ischaemia surrounding the occlusion, the level of myocardial viability, coronary location of the CTO, and probability of procedural success. Moreover, in patients with ST-segment elevation myocardial infarction, a CTO in a noninfarct-related artery might lead to an increase in infarct area, increased end-diastolic left ventricular pressure, and decreased left ventricular function, which are all associated with poor clinical outcomes. In this Review, we provide an overview of the anatomy and histopathology of CTOs, perceived benefits of CTO-PCI, considerations for patient selection for this procedure, and a summary of emerging techniques for CTO-PCI.

Abstract
INTRODUCTION AND OBJECTIVES The prognostic value of chronic total occlusion in nonculprit coronary arteries in patients with myocardial infarction undergoing primary angioplasty remains controversial. Several publications have described different methodologies and conflicting findings. In addition, causes of death were not reported. Our aim is to analyze the prognostic impact of chronic total occlusion in nonculprit coronary arteries and the role of left ventricular ejection fraction in this analysis. METHODS Prospective inclusion of consecutive patients with ST-segment elevation myocardial infarction who underwent primary angioplasty. We recorded baseline characteristics, in-hospital clinical course, and mortality and its causes during follow-up. We assessed the impact of chronic total occlusion on mortality using Cox regression analysis. RESULTS Chronic total occlusion in nonculprit arteries was present in 125 of 1176 patients (10.6%); in 79 of these 125 patients, chronic total occlusion was present in the proximal segments. The mean follow-up was 339 days; 64 (5.8%) patients died during the first 6 months. Patients with chronic total occlusions had more comorbidities, poorer ventricular function, and higher mortality (hazard ratio=2.79; 95% confidence interval, 1.71-4.56). Chronic total occlusion was also associated with noncardiac death (hazard ratio=3.83; 95% confidence interval, 2.10-7.01). Chronic total occlusion in proximal segments was associated with both cardiac (hazard ratio=3.22; 95% confidence interval, 1.42-7.30) and noncardiac deaths (hazard ratio=3.43; 95% confidence interval, 1.67-7.06). The multivariate analysis performed without including left ventricular ejection fraction showed a significant association between chronic total occlusion and mortality. However, when left ventricular ejection fraction was included in the analysis, this association was nonsignificant (hazard ratio=1.76; 95% confidence interval, 0.85-3.65; P=.166). CONCLUSIONS Chronic total occlusion in this clinical setting identified patients at higher risk with more comorbidities and higher mortality, but did not behave as an independent predictor of mortality when left ventricular ejection fraction was included in the analysis.

Evaluation of the effect of concurrent chronic total occlusion and successful staged revascularization on long-term mortality in patients with ST-elevation myocardial infarction.

Abstract
Aims. To investigate the impact of chronic total occlusion (CTO) in non-infarct-related artery (IRA) on the long-term prognosis and evaluate the clinical significance of staged revascularization in patients with ST-segment elevation myocardial infarction (STEMI). Methods. 1266 STEMI patients with primary percutaneous coronary intervention (PCI) were categorized as single-vessel disease (SVD), multivessel disease (MVD) without and with CTO. We study the clinical outcomes of patients after primary PCI in the following 3 years. Additionally, patients with CTO received staged revascularization, and major adverse cardiac events (MACE) during 3-year follow-up were recorded. Results. Presence of CTO was a predictor of both early mortality [hazard ratio (HR) 3.4, 95% confidence interval (CI) 2.4–4.5, P < 0.01] and late mortality (HR 1.9, 95% CI 1.4–3.6, P < 0.01), whereas MVD without CTO was only a predictor of early mortality (HR 1.7, 95% CI 1.3–2.3, P < 0.05). In CTO group, 100 patients had successful CTO recanalization, and 48 patients failed. During 3-year follow-up, patients with failed procedure had higher cardiac mortality (22.9% versus 9.0%, P = 0.020) and lower MACE-free survival (50.0% versus 72.0%, P = 0.009) compared to patients with successful procedure. Conclusion. The presence of CTO and not MVD alone is associated with long-term mortality. Successful revascularization of CTO in the non-IRA is associated with improved clinical outcomes in patients with STEMI undergoing primary PCI.

Abstract
BACKGROUND In chronic total occlusion (CTO), the evidence for revascularization is less robust than for stable angina. A medical therapy strategy is common and often based on distal collateralization, regardless of the presence of ischemia. AIM The aim of this study was to examine the correlation between distal collateralization, myocardial perfusion imaging (MPI), and hard cardiac events (HCE) in CTO. METHOD Retrospective analysis of consecutive patients undergoing coronary angiography revealed 21 non-revascularized patients with CTO and MPI, over a 24-month period. Blinded review of patient charts, MPI, and angiography was undertaken. HCE of death, myocardial infarct, and unstable angina were assessed. Mean follow up was 23 months. RESULTS Summed difference scores were calculated on a 17-segment model and collaterals graded on the Rentrop scale. 43% of patients had HCE, and 62% had collaterals. Ischemia on MPI accurately predicted HCE in CTO (60% vs 0%, P = .01). Distal collateralization failed to predict freedom from ischemia on MPI (31% vs 25%, P = .53) or HCE (31% vs 62%, P = .15). CONCLUSION MPI in patients with CTO accurately predicted HCE. This allows for accurate triage of patients by MPI for consideration of revascularization. Patients without ischemia can be safely managed with optimal medical therapy. The presence of collateralization did not predict either ischemia or HCE.

Abstract
Chronic total occlusion (CTO) in a non-infarct-related artery and chronic kidney failure (CKD) are associated with worse outcomes after primary percutaneous coronary intervention (PCI). The aim of this study was to investigate the interaction of CTO and CKD in patients who underwent primary PCI for acute ST-segment elevation myocardial infarction (STEMI). Patients with STEMIs with or without CKD, defined as an estimated glomerular filtration rate <60 ml/min/1.73 m(2), were categorized into those with single-vessel disease and those with multivessel disease with or without CTO. The primary outcomes were the incidence of 30-day and 1-year mortality. Among 1,873 consecutive patients with STEMIs included between 2006 and 2011, 336 (18%) had CKD. The prevalence of CTO in a non-infarct-related artery was 13% in patients with CKD compared with 7% in those without CKD (p = 0.0003). There was a significant interaction between CKD and CTO on 30-day mortality (p = 0.018) and 1-year mortality (p = 0.013). Independent predictors of late mortality in patients with CKD were previous myocardial infarction (hazard ratio [HR] 1.71, 95% confidence interval [CI] 1.01 to 2.79), age >75 years (HR 1.86, 95% CI 1.19 to 2.95), a left ventricular ejection fraction after primary PCI <40% (HR 2.20, 95% CI 1.36 to 3.63), left main culprit artery (HR 4.46, 95% CI 1.64 to 10.25), and shock (HR 7.44, 95% CI 4.56 to 12.31), but multivessel disease with CTO was not a predictor. In contrast, multivessel disease with CTO was an independent predictor of mortality in patients without CKD (HR 3.30, 95% CI 1.70 to 6.17). In conclusion, in patients with STEMIs who underwent primary PCI, with preexisting CKD, the prevalence of CTO in a non-infarct-related artery was twice as great. In these patients, the clinical impact of CTO seems to be overshadowed by the presence of CKD.

Abstract
After successful primary percutaneous coronary intervention in ST-segment elevation myocardial infarction, adequate myocardial reperfusion is not achieved in up to 50% of patients. This phenomenon of no-reflow is associated with a poor in-hospital and long-term prognosis. Four main factors are thought to contribute to the occurrence of no-reflow: ischaemic injury; reperfusion injury; distal embolization; susceptibility of the microcirculation to injury. This review evaluates the literature, and in particular the clinical trials, concerned with pharmacological and physical methods for prevention and treatment of no-reflow. A number of drugs may improve no-reflow experimentally and clinically, but some have not yet been associated with conclusive improvements in clinical outcome. The complex interacting factors in no-reflow make it unlikely that any single agent will be effective for all patients. Confirmed methods known to be beneficial in the prevention of no-reflow (such as aspirin therapy, chronic statin therapy, blood glucose control, thrombus aspiration in patients with a high thrombus burden and ischaemic preconditioning) should be offered to patients as often as possible, to prevent and treat no-reflow.

Long-term clinical outcomes after percutaneous coronary intervention for chronic total occlusions in elderly patients (≥75 years): five-year outcomes from a 1,791 patient multi-national registry. Catheter Cardiovasc Interv 2013; 82:85-92. [PMID: 23436690 DOI: 10.1002/ccd.24731] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/23/2012] [Revised: 09/20/2012] [Accepted: 10/15/2012] [Indexed: 01/04/2023]
Abstract
OBJECTIVE To investigate procedural success rates and long-term clinical outcome of percutaneous coronary intervention (PCI) for chronic total occlusions (CTO) in elderly patients. BACKGROUND Little is known about procedural success and long-term clinical outcome of PCI for CTO in the elderly. METHODS A total of 1,791 consecutive patients with 1,852 CTO underwent PCI at three large centers in USA, Italy, and South Korea. Outcomes included procedural success and major adverse cardiac events (MACE, composite of mortality, myocardial infarction, or coronary artery bypass graft surgery [CABG]).Time-to-event analyses were performed using Kaplan-Meier statistics, and the log-rank statistic was used to test for differences between patients aged ≥75 and patients aged <75 years. RESULTS Two hundred and thirteen patients (12%) were aged ≥75 years. Procedural success rates were similar in elderly patients compared with patients <75 years (63.8% vs. 69.1%, P = 0.12). Median follow-up was 890 days (IQR: 380-1,480 days). MACE rates after successful versus failed PCI were 25.8% versus 42.3% in the elderly (P = 0.02) and 11.2 versus 20.8% in younger patients (P < 0.01). In elderly patients, this reduction in MACE after successful PCI was mainly driven by a reduction in CABG (0.0% vs. 20.4%, P < 0.01), there were no significant differences in terms of mortality (19.6% vs. 24.6%, P = 0.13) or MI (11.5% vs. 8.0%, P = 0.87). CONCLUSION CTO PCI in patients ≥75 years has similar success as in patients <75 years. In elderly patients undergoing CTO PCI, MACE rates were relatively high but successful revascularization is associated with a reduction in MACE at 5-year follow-up in both elderly and younger patients.

Abstract
OBJECTIVES To determine the prevalence of a concurrent CTO in men and women and to examine its impact on mortality. BACKGROUND The impact of chronic total occlusion (CTO) in patients with ST-elevation myocardial infarction (STEMI) according to gender has not been assessed. METHODS Patients referred with STEMI were categorized into single vessel disease (SVD), multivessel disease (MVD) without, with 1 or > 1 CTO. The primary end-point was the 1-year mortality. RESULTS Among the 2020 STEMI patients included between 2006 and 2011, 24% were female. Women were older, had more hypertension and renal failure (P < 0.0001 for all). The prevalence of 1 or > 1 concurrent CTO was similar in both sexes, 7 and 1%, respectively. Early and late mortality was significantly higher in women compared with men (P < 0.0001). In women, the mortality was significantly worse in patients with > 1 CTO (100%) and with 1 CTO (36.4%) compared with those with MVD without CTO (18.4%) or with SVD (10.4%) (P < 0.0001). MVD with and without concurrent CTO were both independent predictors of 1-year mortality in women (HR 3.58; 95 % CI 1.69-7.18 and HR 2.76; 95 % CI 1.33-5.51) whereas only MVD with CTO was predictive in men (HR 2.19; 95% CI 1.20-3.97). CONCLUSIONS Among unselected STEMI patients, the prevalence of CTO was equal in both sexes whereas early and late mortality remained significantly higher in women. Other factors than the presence of a concurrent CTO must be explored to explain differences in survival after STEMI between women and men.

Abstract
BACKGROUND The association between cardiogenic shock and 1 or >1 chronic total occlusion (CTO) in unselected patients presenting with ST-elevation myocardial infarction (MI) (STEMI) has not been characterized. METHODS Patients with STEMI referred with or without cardiogenic shock were categorized into no CTO, 1 CTO, and >1 CTO. The primary end point was the 30-day mortality. RESULTS Between 2006 and 2011, 2,020 consecutive patients were included. A total of 141 patients (7%) presented with cardiogenic shock on admission. The prevalence of 1 CTO and >1 CTO in a non-infarct-related artery was 23% and 5%, respectively, among patients with shock compared with 6% and 0.5% in patients without shock (P < .0001). Independent predictors of cardiogenic shock included left main-related MI (odds ratio [OR] 6.55, 95% CI 1.39-26.82, P = .019), CTO (OR 4.20, 95% CI 2.64-6.57, P < .001), creatinine clearance <60 mL/min (OR 3.41, 95% CI 2.32-4.99, P < .0001), and left anterior descending-related MI (OR 2.20, 95% CI 1.51-3.23, P < .0001). Thirty-day mortality was 100% in shock patients with >1 CTO, 65.6% with 1 CTO, and 40.2% in patients without CTO (P < .0001). After adjustment for left ventricular ejection fraction and renal function, CTO remained an independent predictor for 30-day mortality (hazard ratio [HR] 1.83; 95% CI 1.10-3.01, P = .02). CONCLUSION In patients with STEMI, CTO was strongly associated with cardiogenic shock on admission. In this setting, mortality was substantially higher in patients with 1 CTO and exceedingly high in those with >1 CTO. The presence of CTO was an independent predictor of early mortality.

Abstract
Chronic total occlusion accounts for 15% of cases during diagnostic angiography with higher referral rate to surgical revascularization. With contemporary strategies and techniques, the success rate with experienced operators can exceed 90%. Currently available observational studies in carefully selected patient populations show evidence of a trend toward symptom relief; improvement in quality of life, left ventricular function, and mortality; and improved tolerance toward future ischemic events. Lack of randomized controlled trials comparing current optimal medical management with percutaneous coronary intervention for chronic total occlusion is a major barrier to widespread adaptation of this advanced complex interventional technique.

Comparison of five-year outcomes of patients with and without chronic total occlusion of noninfarct coronary artery after primary coronary intervention for ST-segment elevation acute myocardial infarction. Am J Cardiol 2012; 109:208-13.

Abstract
The aim of the present study was to evaluate the effect of concurrent chronic total occlusion (CTO) in a noninfarct-related artery (IRA) on the long-term prognosis in patients with ST-segment elevation myocardial infarction and multivessel coronary disease. Of 1,658 consecutive patients with ST-segment elevation myocardial infarction, 666 with multivessel coronary disease who underwent percutaneous coronary intervention from 1999 to 2004 were included in the present analysis. The patients were divided into 2 groups: no CTO and CTO. The first group included 462 patients without CTO (69%) and the second group included 204 patients with CTO in a non-IRA (31%). The in-hospital mortality rate was 6.3% and 21.1% (p < 0.0001) and the 5-year mortality rate was 22.5% and 40.2% (p < 0.0001) for the no-CTO and CTO patients, respectively. Multivariate analysis revealed that after correction for baseline differences CTO in a non-IRA was a strong, independent predictor of 5-year mortality in patients undergoing percutaneous coronary intervention (hazard ratio 1.85; 95% confidence interval 1.35 to 2.53; p = 0.0001). In conclusion, the presence of CTO in a non-IRA in patients with ST-segment elevation myocardial infarction and multivessel coronary disease is a strong and independent risk factor for greater 5-year mortality.

Abstract
AIMS We sought to investigate the impact of multivessel disease (MVD) with and without a chronic total occlusion (CTO) in a non-infarct-related artery (IRA) on mortality in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI). METHODS AND RESULTS In the HORIZONS-AMI trial, of 3283 patients undergoing primary PCI, 1524 patients (46.4%) had single-vessel disease (SVD), 1477 (45.0%) had MVD without a CTO, and 283 (8.6%) had MVD with a CTO in a non-IRA. Compared with SVD patients and MVD patients without a CTO, patients with a non-IRA CTO were significantly less likely to achieve post-procedural TIMI 3 flow (P = 0.0003), more often had absent myocardial blush (P = 0.0002), and less frequently achieved complete ST-segment resolution (P = 0.0001). By multivariable analysis, MVD with CTO in a non-IRA was an independent predictor of both 0- to 30-day mortality [hazard ratio (HR) 2.88, 95% confidence interval (CI) 1.41-5.88, P = 0.004] and 30-day to 3-year mortality (HR 1.98, 95% CI 1.19-3.29, P= 0.009), while MVD without a CTO was a significant predictor for 0- to 30-day mortality (HR 2.20, 95% CI 1.00-3.06, P = 0.049) but not late mortality. CONCLUSION In patients with STEMI undergoing primary PCI in the HORIZONS-AMI trial, MVD with or without a CTO in a non-IRA was an independent predictor of early mortality. The presence of a CTO in a non-IRA was also an independent predictor of increased late mortality to 3 years.

Abstract
BACKGROUND Recently, a chronic total occlusion (CTO) in the non-infarct-related artery (non-IRA) was reported as an independent predictor of clinical outcome in patients with acute ST-segment elevation myocardial infarction (STEMI). The aim of this study was to investigate the clinical significance of staged revascularization for a CTO in the non-IRA for patients with STEMI. METHODS A total of 136 patients with acute STEMI undergoing primary percutaneous coronary intervention (PCI) received staged revascularization (ranging 7-10 days) for a CTO in the non-IRA. Cardiac mortality and major adverse cardiac events (MACE) including death, recurrent myocardial infarction, repeat revascularization, and re-hospitalization because of heart failure during 2-year follow-up were recorded. RESULTS Recanalization of totally occluded lesions in the non-IRA was successful in 87 (64%) patients for 93 lesions but failed in 49 (36%) patients. During 2-year follow-up, cardiac mortality was lower (8.0% vs. 20.4%, p = 0.036) and MACE-free survival was higher (78.2% vs. 61.2%, p = 0.042) in patients with successful than in those with failed revascularization of a CTO in the non-IRA. Multivariable analysis showed that after adjustment for possible confounders, successful recanalization of a CTO in the non-IRA was an independent predictor for 2-year cardiac mortality (HR = 0.145, 95% CI 0.047-0.446, P = 0.001) and MACE-free survival (HR = 0.430, 95%CI 0.220-0.838, P = 0.013). CONCLUSION Successful revascularization of a CTO in the non-IRA is associated with improved clinical outcomes in patients with STEMI undergoing primary PCI.

Abstract
Background In the setting of primary percutaneous coronary intervention, patients with a chronic total occlusion in a non-infarct related artery were recently identified as a high-risk subgroup. It is unclear whether ST-elevation myocardial infarction patients with a chronic total occlusion in a non-infarct related artery should undergo additional percutaneous coronary intervention of the chronic total occlusion on top of optimal medical therapy shortly after primary percutaneous coronary intervention. Possible beneficial effects include reduction in adverse left ventricular remodeling and preservation of global left ventricular function and improved clinical outcome during future coronary events. Methods/Design The Evaluating Xience V and left ventricular function in Percutaneous coronary intervention on occLusiOns afteR ST-Elevation myocardial infarction (EXPLORE) trial is a randomized, prospective, multicenter, two-arm trial with blinded evaluation of endpoints. Three hundred patients after primary percutaneous coronary intervention for ST-elevation myocardial infarction with a chronic total occlusion in a non-infarct related artery are randomized to either elective percutaneous coronary intervention of the chronic total occlusion within seven days or standard medical treatment. When assigned to the invasive arm, an everolimus-eluting coronary stent is used. Primary endpoints are left ventricular ejection fraction and left ventricular end-diastolic volume assessed by cardiac Magnetic Resonance Imaging at four months. Clinical follow-up will continue until five years. Discussion The ongoing EXPLORE trial is the first randomized clinical trial powered to investigate whether recanalization of a chronic total occlusion in a non-infarct related artery after primary percutaneous coronary intervention for ST-elevation myocardial infarction results in a better preserved residual left ventricular ejection fraction, reduced end-diastolic volume and enhanced clinical outcome.
