Abstract
Shortening the duration of dual-antiplatelet therapy (DAPT) after percutaneous coronary intervention (PCI) was shown to be effective and safe in patients at high bleeding risk (HBR). We aimed to investigate the effect of 1 versus 3-month DAPT on outcomes after drug-eluting stent in HBR patients with or without chronic kidney disease (CKD). Data from 3 prospective single-arm studies (XIENCE Short DAPT Program) enrolling HBR patients after successful coronary implantation of cobalt-chromium everolimus-eluting stent (XIENCE, Abbott) were analyzed. Subjects were eligible for DAPT discontinuation at 1 or 3 months if free from ischemic events. The primary end point was all-cause death or any myocardial infarction. The key secondary end point was Bleeding Academic Research Consortium Type 2 to 5 bleeding. Outcomes were assessed from 1 to 12 months after PCI. CKD was defined as baseline creatinine clearance <60 ml/min. Of 3,286 patients, 1,432 (43.6%) had CKD. One-month versus 3-month DAPT was associated with a similar 12-month risk of the primary outcome irrespective of CKD status (CKD: 9.5% vs 10.9%, adjusted hazard ratio 0.86, 95% confidence interval 0.60 to 1.22; no-CKD: 6.6% vs 5.6%, adjusted hazard ratio 1.15, 95% confidence interval 0.77 to 1.73; p interaction 0.299). Bleeding Academic Research Consortium 2 to 5 bleeding rates were numerically but not significantly lower with 1-month versus 3-month DAPT in both CKD (9.9% vs 12%) and no-CKD (6.4% vs 9.0%) patients. In conclusion, in HBR patients, 1-month versus 3-month DAPT was associated with a similar risk of ischemic complications and a trend toward fewer bleeding events at 12 months after PCI, irrespective of CKD status.

Abstract
Aims Dual antiplatelet therapy (DAPT) can be shortened up to 1 month in high-bleeding risk (HBR) patients receiving a contemporary biodegradable-polymer sirolimus-eluting stent. We aimed to summarize the evidence on a similar DAPT regimen after biodegradable-polymer everolimus-eluting stent (EES) implantation in patients at HBR. Methods and results We pooled the individual participant data from the available trials evaluating this strategy, namely, the SENIOR and the POEM trials. Inclusion criteria were ≥1 biodegradable-polymer EES implantation and ≤1-month duration of DAPT. The primary endpoint was the 1-year composite of cardiovascular death, myocardial infarction, or stroke. Major bleeding was defined as Bleeding Academic Research Consortium (BARC) type 3-5 bleeding. Landmark analyses were performed at 1 month, the time point for intended DAPT interruption. We included 766 participants (age 77.5 ± 8.2 years, women 31.9%), 323 from the SENIOR and 443 from the POEM trial. The primary endpoint occurred in 45 participants (6.0%; 95% confidence interval [CI], 4.3-7.7%) through 1 year of follow-up, with 21 (2.8%; 95% CI, 1.6-3.9%) events during the first month and 24 (3.4%; 95% CI, 2.0-4.7%) thereafter. The incidences of cardiovascular death, myocardial infarction, and stroke were 2.2% (95% CI, 0.36-2.50%), 3.1% (95% CI, 1.8-4.3%), and 1.2% (95% CI, 0.4-2.0%), respectively. BARC type 3-5 bleeding ocuurred in 1.1% (95% CI, 0.3-1.8%) at 1 month and 2.9% (95% CI, 1.6-4.1%) at 1 year. Conclusion HBR patients receiving biodegradable-polymer EES had few ischemic and bleeding events when given 1 month of DAPT. One-month DAPT after biodegradable-polymer EES implantation seems safe in patients at HBR.

Abstract
Coronary artery disease in older patients is more frequently diffuse and complex, and is often treated by percutaneous coronary intervention on top of medical therapy. There are currently no specific recommendations for antiplatelet therapy in patients aged≥75 years. Aspirin remains pivotal, and is still indicated as a long-term treatment after percutaneous coronary intervention. In addition, a P2Y12 inhibitor is administered for 6-12 months according to clinical presentation. Age is a minor bleeding risk factor, but because older patients often have several co-morbidities, they are considered as having a high bleeding risk according to different scoring systems. This increased bleeding risk has resulted in different therapeutic strategies for antithrombotic treatment after percutaneous coronary intervention; these include short dual antiplatelet therapy, a switch from potent to less potent antiplatelet therapy or single antiplatelet therapy with a P2Y12 inhibitor instead of aspirin, among others. A patient-centred approach, taking into account health status, functional ability, frailty, cognitive skills, bleeding and ischaemic risks and patient preference, is essential when caring for older adults with coronary artery disease. The present review focuses on the knowledge base, specificities of antiplatelet therapies, a balance between haemorrhagic and ischaemic risk, strategies for antiplatelet therapy and directions for future investigation pertaining to coronary artery disease in older patients.

Abstract
BACKGROUND A short dual antiplatelet therapy (DAPT) duration has been proposed for patients at high bleeding risk (HBR) undergoing drug-eluting coronary stent (DES) implantation. Whether this strategy is safe and effective after a non-ST-segment elevation acute coronary syndrome (NSTE-ACS) remains uncertain. AIMS We aimed to compare the impact of 1-month versus 3-month DAPT on clinical outcomes after DES implantation among HBR patients with or without NSTE-ACS. METHODS This is a prespecified analysis from the XIENCE Short DAPT programme involving three prospective, international, single-arm studies evaluating the safety and efficacy of 1-month (XIENCE 28 USA and Global) or 3-month (XIENCE 90) DAPT among HBR patients after implantation of a cobalt-chromium everolimus-eluting stent. Ischaemic and bleeding outcomes associated with 1- versus 3-month DAPT were assessed according to clinical presentation using propensity score stratification. RESULTS Of 3,364 HBR patients (1,392 on 1-month DAPT and 1,972 on 3-month DAPT), 1,164 (34.6%) underwent DES implantation for NSTE-ACS. At 12 months, the risk of the primary endpoint of death or myocardial infarction was similar between 1- and 3-month DAPT in patients with (hazard ratio [HR] 1.09, 95% confidence interval [CI]: 0.71-1.65) and without NSTE-ACS (HR 0.88, 95% CI: 0.63-1.23; p-interaction=0.34). The key secondary endpoint of Bleeding Academic Research Consortium (BARC) Type 2-5 bleeding was consistently reduced in both NSTE-ACS (HR 0.57, 95% CI: 0.37-0.88) and stable patients (HR 0.84, 95% CI: 0.61-1.15; p-interaction=0.15) with 1-month DAPT. CONCLUSIONS Among HBR patients undergoing implantation of an everolimus-eluting stent, 1-month, compared to 3-month DAPT, was associated with similar ischaemic risk and reduced bleeding at 1 year, irrespective of clinical presentation.

Abstract
BACKGROUND Oncological patients with coronary artery disease face an elevated risk of hemorrhagic and ischemic events following percutaneous coronary intervention. Despite medical guidelines recommending minimal dual antiplatelet therapy (DAPT) duration for patients with cancer, dedicated data on abbreviated DAPT in this population is lacking. This study aims to evaluate the occurrence of ischemic and hemorrhagic events in patients with cancer compared with other high-bleeding risk individuals. METHODS Patient-level data from 4 high-bleeding risk coronary drug-eluting stent studies (ONYX One, LEADERS FREE, LEADERS FREE II, and SENIOR trials) treated with short DAPT were analyzed. The comparison focused on patients with high-bleeding risk with and without cancer, assessing 1-year rates of net adverse clinical events (all-cause death, myocardial infarction, stroke, revascularization, and Bleeding Academic Research Consortium [BARC] types 3 to 5 bleeding) and major adverse clinical events (all-cause death, myocardial infarction, stroke). RESULTS A total of 5232 patients were included, of whom 574 individuals had cancer, and 4658 were at high-bleeding risk without previous cancer. Despite being younger with fewer risk factors, patients with cancer had higher net adverse clinical event (HR, 1.25; P=0.01) and major adverse clinical event (HR, 1.26; P=0.02), primarily driven by all-cause mortality and major bleeding (BARC 3-5), but not myocardial infarction, stroke, stent thrombosis, or repeat revascularization. Cancer was an independent predictor of net adverse clinical event (P=0.005), major adverse clinical event (P=0.01), and major bleeding (P=0.03). CONCLUSIONS The present work is the first report on abbreviated DAPT dedicated to patients with cancer. Cancer is a major marker of adverse outcomes and these events had high lethality. Despite short DAPT, patients with cancer experienced higher rates of major bleeding compared with patients without cancer with high-bleeding risk, which occurred mainly after DAPT discontinuation. These findings reinforce the need for a more detailed and individualized stratification of those patients.

Abstract
This analysis aimed to evaluate the effect of 1- versus 3-month dual antiplatelet therapy (DAPT) after percutaneous coronary intervention (PCI) in older patients. Data from 3 prospective, single-arm studies (XIENCE Short DAPT Program), including patients with high bleeding risk successfully treated with an everolimus-eluting stent (XIENCE, Abbott) were analyzed. DAPT was discontinued at 1 or at 3 months in patients free from ischemic events and adherent to DAPT. Patients were stratified according to age (≥75 and <75 years). The primary end point was all-cause death or myocardial infarction (MI). The key secondary end point was Bleeding Academic Research Consortium type 2 to 5 bleeding. The outcomes were assessed from 1 to 12 months after index PCI. Of 3,364 patients, 2,241 (66.6%) were aged ≥75 years. The risk of death or MI was similar with 1- versus 3-month DAPT in patients aged ≥75 (8.5% vs 8.0%, adjusted hazard ratio [HR] 0.95, 95% confidence interval [CI] 0.69 to 1.30) and <75 years (6.9% vs 7.8%, adjusted HR 0.97, 95% CI 0.60 to 1.57, interaction p = 0.478). Bleeding Academic Research Consortium type 2 to 5 bleeding was consistently lower with 1- than with 3-month DAPT in patients aged ≥75 years (7.2% vs 9.4%, adjusted HR 0.66, 95% CI 0.48 to 0.91) and <75 years (9.7% vs 11.9%, adjusted HR 0.86, 95% CI 0.57 to 1.29, interaction p = 0.737). In conclusion, in patients at high bleeding risk who underwent PCI, patients older and younger than 75 years derived a consistent benefit from 1- compared with 3-month DAPT in terms of bleeding reduction, with no increase in all-cause death or MI at 1 year.

Abstract
BACKGROUND Patent foramen ovale (PFO) is causally associated with stroke in some patients younger than 60 years, especially when it is large or associated with an atrial septal aneurysm (ASA). After 60 years of age, this association is less well understood. We assessed the relationships between detailed atrial septal anatomy and the cryptogenic nature of stroke in this population. METHODS AND RESULTS We reviewed all patients aged 60 to 80 years admitted to our stroke center for ischemic stroke who underwent contrast echocardiography between 2016 and 2021. The atherosclerosis, small-vessel disease, cardiac pathology, other causes, and dissection (ASCOD) classification was used to reevaluate the etiological workup. Associations between cryptogenic stroke and (1) PFO presence or (2) categories of PFO anatomy (nonlarge PFO without ASA, nonlarge PFO with ASA, large PFO without ASA, and large PFO with ASA) were assessed using logistic regression. Among 533 patients (median National Institutes of Health Stroke Scale score=1), PFO was present in 152 (prevalence, 28.5% [95% CI, 24.9-32.5]). Compared with noncryptogenic stroke, cryptogenic stroke (n=218) was associated with PFO presence (44.5% versus 17.5%; P<0.0001). Among patients with a PFO, septal anatomy categories were associated with cryptogenic stroke (P=0.02), with a strong association for patients with both large PFO and ASA (38.1% versus 14.5%, P=0.002). CONCLUSIONS PFO presence remains strongly associated with cryptogenic stroke between 60 and 80 years of age. Large PFO, ASA, and their association were strongly associated with cryptogenic stroke in this age group. Our results support performing contrast echocardiography even after 60 years of age, although the optimal secondary prevention therapy in this population remains to be determined in randomized trials.

Abstract
BACKGROUND Whether ticagrelor in chronic coronary syndrome patients undergoing complex percutaneous coronary intervention (PCI) can prevent cardiovascular events is unknown. OBJECTIVES The authors sought to evaluate outcomes of complex PCI and the efficacy of ticagrelor vs clopidogrel in stable patients randomized in the ALPHEUS (Assessment of Loading with the P2Y12 inhibitor ticagrelor or clopidogrel to Halt ischemic Events in patients Undergoing elective coronary Stenting) trial. METHODS All PCI procedures were blindly reviewed and classified as complex if they had at least 1 of the following criteria: stent length >60 mm, 2-stent bifurcation, left main, bypass graft, chronic total occlusion, use of atherectomy or guiding catheter extensions, multiwire technique, multiple stents. The primary endpoint was a composite of type 4a or b myocardial infarction (MI) and major myocardial injury during the 48 hours after PCI. We compared the event rates according to the presence or not of complex PCI criteria and evaluated the interaction with ticagrelor or clopidogrel. RESULTS Among the 1,866 patients randomized, 910 PCI (48.3%) were classified as complex PCI. The primary endpoint was more frequent in complex PCI (45.6% vs 26.6%; P < 0.001) driven by higher rates of type 4 MI and angiographic complications (12.2% vs 4.8 %; P < 0.001 and 19.3% vs 8.6%; P < 0.05, respectively). The composite of death, MI, and stroke at 48 hours (12.7% vs 5.1 %; P < 0.05) and at 30 days (13.4% vs 5.3%; P < 0.05) was more frequent in complex PCI. No interaction was found between PCI complexity and the randomized treatment for the primary endpoint (Pinteraction = 0.47) nor the secondary endpoints. CONCLUSIONS In chronic coronary syndrome, patients undergoing a complex PCI have higher rates of periprocedural and cardiovascular events that are not reduced by ticagrelor as compared with clopidogrel.

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 We hypothesized that a prolonged follow-up of survivors of unexplained sudden cardiac arrest (USCA) would subsequently unmask electrical heart disorders in a significant proportion of cases. PATIENTS AND METHODS We retrospectively analyzed all out-of-hospital cardiac arrest (OHCA) admitted alive in our cardiac arrest center over 20-years (2002-2022). The diagnosis of USCA was made when no etiology was found after thorough initial hospital investigations. We identified all the new diagnoses established during follow-up, and compared outcomes according to underlying heart diseases. RESULTS Out of the 2482 OHCA patients, 68 (2.7%) were initially classified as USCA and 30 (1.2%) with electrical heart disorders. Compared to other cardiac etiologies of OHCA, both USCA and electrical heart disorders patients were younger (mean age 48.5 and 43.5 year-old respectively, versus 62.5 year-old; p < 0.0001), with a higher rate of family history of SCA (17.6 and 23.3% respectively versus 9.2%; p = 0.003). Six patients in each group were lost to follow-up at discharge (6/68, 8.8% in the USCA group, 6/30 20% in the electrical heart disorders group). During a mean follow-up of 8.1 ± 6.3 years, a diagnosis was eventually established in 24.3% of USCA patients (9/35), most of them as electrical heart disorders (55.6%, 5/9). No post-discharge death occurred in both USCA and electrical heart disorders groups, with approximately 10% of appropriate therapy delivered by the implantable cardioverter defibrillator. CONCLUSION Our findings emphasized that approximately a quarter of patients who had been initially considered as having apparently USCA after index hospital stay actually reveal heart conditions, especially electrical heart disorders.

Abstract
Cardiovascular disease, including ischemic heart disease, is the leading cause of death worldwide, and percutaneous coronary interventions (PCIs) have been demonstrated to improve the prognosis of these patients on top of optimal medical therapy. PCIs have evolved from plain old balloon angioplasty to coronary stent implantation at the end of the last century. There has been a constant technical and scientific improvement in stent technology from bare metal stents to the era of drug-eluting stents (DESs) to overcome clinical challenges such as target lesion failure related to in-stent restenosis or stent thrombosis. A better understanding of the underlying mechanisms of these adverse events has led DESs to evolve from first-generation DESs to thinner and ultrathin third-generation DESs with improved polymer biocompatibility that seems to have reached a peak in efficiency. This review aims to provide a brief historical overview of the evolution of coronary DES platforms and an update on clinical studies and major characteristics of the most currently used DESs.

Abstract
BACKGROUND The optimal duration of dual antiplatelet therapy (DAPT) after percutaneous coronary intervention (PCI) in patients on long-term oral anticoagulation (OAC) therapy is still uncertain. OBJECTIVES The aim of this analysis was to assess the effects of 1- vs 3-month DAPT in patients with and those without concomitant OAC included in the XIENCE Short DAPT program. METHODS The XIENCE Short DAPT program enrolled patients with high bleeding risk who underwent successful PCI with a cobalt-chromium everolimus-eluting stent. DAPT was discontinued at 1 or 3 months in patients free from ischemic events and adherent to treatment. The effect of 1- vs 3-month DAPT was compared in patients with and those without OAC using propensity score stratification. The primary endpoint was all-cause death or any myocardial infarction (MI). The key secondary endpoint was Bleeding Academic Research Consortium (BARC) types 2 to 5 bleeding. Outcomes were assessed from 1 to 12 months after index PCI. RESULTS Among 3,364 event-free patients, 1,462 (43%) were on OAC. Among OAC patients, the risk for death or MI was similar between 1- and 3-month DAPT (7.4% vs 8.8%; adjusted HR: 0.74; 95% CI: 0.49-1.11; P = 0.139), whereas BARC types 2 to 5 bleeding was lower with 1-month DAPT (adjusted HR: 0.71; 95% CI: 0.51-0.99; P = 0.046). These effects were consistent in patients with and those without OAC (P for interaction = NS). CONCLUSIONS Between 1 and 12 months after PCI, 1-month compared with 3-month DAPT was associated with similar rates of all-cause death or MI and a reduced rate of BARC types 2 to 5 bleeding, irrespective of OAC treatment.

Abstract
About 70% of out-of-hospital cardiac arrests are related to an ischaemic heart disease in Western countries. Percutaneous coronary intervention has been shown to improve the prognosis of survivors when an unstable coronary lesion is identified as the potential cause of the cardiac arrest. Acute complete coronary occlusion is often demonstrated among patients with ST-segment elevation on electrocardiogram after the return of spontaneous circulation. In patients without ST-segment elevation, routine coronary angiography has been shown to be not superior to conservative management. However, an electrocardiogram-based decision to perform immediate coronary angiography could be insufficient to identify unstable coronary lesions, which are frequently associated with intermediate coronary stenosis. Intracoronary imaging can be helpful to detect plaque rupture or erosion and intracoronary thrombus, but could also lead to better stent implantation, and help to reduce the risk of stent thrombosis. In patients with coronary lesions without the instability characteristic, conservative management should be the default strategy, and a search for another cause of the cardiac arrest should be systematic. In the present review, we sought to describe the potential benefit of intracoronary imaging in patients with out-of-hospital cardiac arrest.

Abstract
BACKGROUND The prevalence and significance of abnormal epicardial coronary vasomotor reactivity (ACVR) in patients with symptoms compatible with myocardial ischaemia remains ill-defined. Our diagnostic strategy is to perform a provocative test (PT) in every patient presenting with chest pain at rest, for whom coronary angiography does not reveal significant epicardial coronary artery disease (≥70% stenosis by visual assessment). AIM To evaluate such a strategy in terms of incidence of ACVR, PT safety and patient outcomes. METHODS The present study was a retrospective observational study with a median clinical follow-up of 5years. The primary outcome was incidence of ACVR in patients with PT. Risk factors for ACVR and clinical follow-up were obtained, and the rate of major adverse cardiovascular and cerebrovascular events (MACCE; death, cardiovascular mortality, myocardial infarction, stroke and coronary revascularization) was reported. RESULTS ACVR was documented in 294 (12.4%) of the 2379 patients with PT, out of the 13,654 patients undergoing angiography. Patients with ACVR were more often female (43.9% vs. 30.0%; P<0.0001), current smokers (37.4% vs. 8.7%; P<0.0001) and had a suspected acute coronary syndrome (36.7% vs. 29.1%; P=0.005) at admittance compared with patients without ACVR. During clinical follow-up, MACCE occurred more frequently in patients with (9.8%) than in those without (3.7%) ACVR (hazard ratio [HR] 4.15, 95% confidence interval [CI] 2.62-6.57; P<0.0001), including more myocardial infarctions (4.0% vs. 0.4%; HR 17.8, 95% CI 6.41-49.5; P<0.0001) and more myocardial revascularizations (6.1% vs. 1.1%; HR 9.36, 95% CI 4.67-18.74; P<0.0001) compared with patients with normal PT at baseline. CONCLUSIONS ACVR is frequent in patients with symptoms compatible with myocardial ischaemia at rest, with no significant coronary stenosis. PT is a safe strategy to identify a population at high risk of recurrent ischaemic events.

Abstract
BACKGROUND Recent guidelines have emphasized actively avoiding fever to improve outcomes in patients who are comatose following resuscitation from cardiac arrest (ie, out-of-hospital cardiac arrest). However, whether targeted temperature management between 32 °C and 36 °C (TTM32-36) can improve neurologic outcome in some patients remains debated. RESEARCH QUESTION Is there an association between the use of TTM32-36 and outcome according to severity assessed at ICU admission using a previously derived risk score? STUDY DESIGN AND METHODS Data prospectively collected in the Sudden Death Expertise Center (SDEC) registry (France) between May 2011 and December 2017 and in the Resuscitation Outcomes Consortium Continuous Chest Compressions (ROC-CCC) trial (United States and Canada) between June 2011 and May 2015 were used for this study. Severity at ICU admission was assessed through a modified version of the Cardiac Arrest Hospital Prognosis (mCAHP) score, divided into tertiles of severity. The study explored associations between TTM32-36 and favorable neurologic status at hospital discharge by using multiple logistic regression as well as in tertiles of severity for each data set. RESULTS A total of 2,723 patients were analyzed in the SDEC data set and 4,202 patients in the ROC-CCC data set. A favorable neurologic status at hospital discharge occurred in 728 (27%) patients in the French data set and in 1,239 (29%) patients in the North American data set. Among the French data set, TTM32-36 was independently associated with better neurologic outcome in the tertile of patients with low (adjusted OR, 1.63; 95% CI, 1.15-2.30; P = .006) and high (adjusted OR, 1.94; 95% CI, 1.06-3.54; P = .030) severity according to mCAHP at ICU admission. Similar results were observed in the North American data set (adjusted ORs of 1.36 [95% CI, 1.05-1.75; P = .020] and 2.42 [95% CI, 1.38-4.24; P = .002], respectively). No association was observed between TTM32-36 and outcome in the moderate groups of the two data sets. INTERPRETATION TTM32-36 was significantly associated with a better outcome in patients with low and high severity at ICU admission assessed according to the mCAHP score. Further studies are needed to evaluate individualized temperature control following out-of-hospital cardiac arrest.

Abstract
AIMS Data on sports-related sudden cardiac arrest (SrSCA) among young adults in the general population are scarce. We aimed to determine the overall SrSCA incidence, characteristics, and outcomes in young adults. METHODS AND RESULTS Prospective cohort study of all cases of SrSCA between 2012 and 2019 in Germany and Paris area, France, involving subjects aged 18-35 years. Detection of SrSCA was achieved via multiple sources, including emergency medical services (EMS) reporting and web-based screening of media releases. Cases and aetiologies were centrally adjudicated. Overall, a total of 147 SrSCA (mean age 28.1 ± 4.8 years, 95.2% males) occurred, with an overall burden of 4.77 [95% confidence interval (CI) 2.85-6.68] cases per million-year, including 12 (8.2%) cases in young competitive athletes. While bystander cardiopulmonary resuscitation (CPR) was initiated in 114 (82.6%), automated external defibrillator (AED) use by bystanders occurred only in a minority (7.5%). Public AED use prior to EMS arrival (odds ratio 6.25, 95% CI 1.48-43.20, P = 0.02) was the strongest independent predictor of survival at hospital discharge (38.1%). Among cases that benefited from both immediate bystander CPR and AED use, survival rate was 90.9%. Coronary artery disease was the most frequent aetiology (25.8%), mainly through acute coronary syndrome (86.9%). CONCLUSION Sports-related sudden cardiac arrest in the young occurs mainly in recreational male sports participants. Public AED use remains disappointingly low, although survival may reach 90% among those who benefit from both bystander CPR and early defibrillation. Coronary artery disease is the most prevalent cause of SrSCA in young adults.

Abstract
New-generation drug-eluting stents (DES) strongly reduce restenosis and repeat revascularization compared with bare-metal stents (BMS) for percutaneous coronary intervention. There is residual uncertainty as to whether other prognostically relevant outcomes are affected by DES versus BMS concerning initial presentation (chronic coronary syndrome [CCS] vs acute coronary syndrome [ACS]). We performed an individual patient data meta-analysis of randomized trials comparing new-generation DES versus BMS (CRD42017060520). The primary outcome was the composite of cardiac death or myocardial infarction (MI). Outcomes were examined at maximum follow-up and with a 1-year landmark. Risk estimates are expressed as hazard ratio (HR) with 95% confidence interval (CI). A total of 22,319 patients were included across 14 trials; 7,691 patients (34.5%) with CCS and 14,628 patients (65.5%) with ACS. We found evidence that new-generation DES versus BMS consistently reduced the risk of cardiac death or MI in both patients with CCS (HR 0.83, 95% CI 0.70 to 0.98, p <0.001) and ACS (HR 0.83, 95% CI 0.75 to 0.92, p <0.001) (p-interaction = 0.931). This benefit was mainly driven by a similar reduction in the risk of MI (p-interaction = 0.898) for both subsets (HRCCS 0.80, 95% CI 0.65 to 0.97; HRACS 0.79, 95% CI 0.70 to 0.89). In CCS and ACS, we found a time-dependent treatment effect, with the benefit from DES accumulating during 1-year follow-up, without offsetting effects after that. In conclusion, patients with CCS were slightly underrepresented in comparative clinical trials. Still, they benefited similarly to patients with ACS from new-generation DES instead of BMS with a sustained reduction of cardiac death or MI because of lower event rates within 1 year.

Abstract
Importance Although an emergency coronary angiogram (CAG) is recommended for patients who experience an out-of-hospital cardiac arrest (OHCA) with ST-segment elevation on the postresuscitation electrocardiogram (ECG), this strategy is still debated in patients without ST-segment elevation. Objective To assess the 180-day survival rate with Cerebral Performance Category (CPC) 1 or 2 of patients who experience an OHCA without ST-segment elevation on ECG and undergo emergency CAG vs delayed CAG. Design, Setting, and Participants The Emergency vs Delayed Coronary Angiogram in Survivors of Out-of-Hospital Cardiac Arrest (EMERGE) trial randomly assigned survivors of an OHCA without ST-segment elevation on ECG to either emergency or delayed (48 to 96 hours) CAG in 22 French centers. The trial took place from January 19, 2017, to November 23, 2020. Data were analyzed from November 24, 2020, to July 30, 2021. Main Outcomes and Measures The primary outcome was the 180-day survival rate with CPC of 2 or less. The secondary end points were occurrence of shock, ventricular tachycardia, and/or fibrillation within 48 hours, change in left ventricular ejection fraction between baseline and 180 days, CPC scale at intensive care unit discharge and day 90, survival rate, and hospital length of stay. Results A total of 279 patients (mean [SD] age, 64.7 [14.6] years; 195 men [69.9%]) were enrolled, with 141 (50.5%) in the emergency CAG group and 138 (49.5%) in the delayed CAG group. The study was underpowered. The mean (SD) time delay between randomization and CAG was 0.6 (3.7) hours in the emergency CAG group and 55.1 (37.2) hours in the delayed CAG group. The 180-day survival rates among patients with a CPC of 2 or less were 34.1% (47 of 141) in the emergency CAG group and 30.7% (42 of 138) in the delayed CAG group (hazard ratio [HR], 0.87; 95% CI, 0.65-1.15; P = .32). There was no difference in the overall survival rate at 180 days (emergency CAG, 36.2% [51 of 141] vs delayed CAG, 33.3% [46 of 138]; HR, 0.86; 95% CI, 0.64-1.15; P = .31) and in secondary outcomes between the 2 groups. Conclusions and Relevance In this randomized clinical trial, for patients who experience an OHCA without ST-segment elevation on ECG, a strategy of emergency CAG was not better than a strategy of delayed CAG with respect to 180-day survival rate and minimal neurologic sequelae.

Abstract
BACKGROUND Since majority of sudden cardiac arrest (SCA) victims die in the intensive care unit (ICU), early etiologic investigations may improve understanding of SCA and targeted prevention. METHODS In this prospective, population-based registry all SCA admitted alive across the 48 hospitals of the Paris area were enrolled. We investigated the extent of early etiologic work-up among young SCD cases (<45 years) eventually dying within the ICU. RESULTS From May 2011 to May 2018, 4,314 SCA patients were admitted alive. Among them, 3,044 died in ICU, including 484 (15.9%) young patients. SCA etiology was established in 233 (48.1%) and remained unexplained in 251 (51.9%). Among unexplained (compared to explained) cases, coronary angiography (17.9 vs. 49.4%, P<0.001), computed tomography scan (24.7 vs. 46.8%, P<0.001) and trans-thoracic echocardiography (31.1 vs. 56.7%, P<0.001) were less frequently performed. Only 22 (8.8%) patients with unexplained SCD underwent all three investigations. SCDs with unexplained status decreased significantly over the 7 years of the study period (from 62.9 to 35.2%, P=0.005). While specialized TTE and CT scan performances have increased significantly, performance of early coronary angiography did not change. Autopsy, genetic analysis and family screening were performed in only 48 (9.9%), 5 (1.0%) and 14 cases (2.9%) respectively. CONCLUSIONS More than half of young SCD dying in ICU remained etiologically unexplained; this was associated with a lack of early investigations. Improving early diagnosis may enhance both SCA understanding and prevention, including for relatives.

Abstract
BACKGROUND In patients with ST-segment elevation myocardial infarction (STEMI) who have multivessel disease, the FLOWER-MI trial found no significant clinical benefit to fractional flow reserve (FFR)-guided percutaneous coronary intervention (PCI) compared to angiography-guided PCI. AIMS Our aim was to estimate the cost-effectiveness and cost-utility of FFR-guided PCI, the secondary endpoint of the FLOWER-MI trial. METHODS Costs, major adverse cardiovascular events (composite of all-cause death, non-fatal myocardial infarction [MI], and unplanned hospitalisation leading to urgent revascularisation), and quality-adjusted life years were calculated in both groups. The incremental cost-effectiveness and cost-utility ratios were estimated. Uncertainty was explored by probabilistic bootstrapping. The analysis was conducted from the perspective of the health care provider with a time horizon of one year. RESULTS At one year, the average cost per patient was 7,560€ (±2,218) in the FFR-guided group and 7,089€ (±1,991) in the angiography-guided group (p-value<0.01). The point estimates for the incremental cost-effectiveness and cost-utility ratios found that the angiography-guided strategy was cost saving and improved outcomes, with a probabilistic sensitivity analysis confirming dominance. CONCLUSIONS The FFR-guided strategy at one year is unlikely to be cost effective compared to the angiography-guided strategy on both clinical and quality of life outcomes.
