Sex-specific Prediction of Cardiogenic Shock After Acute Coronary Syndromes: The SEX-SHOCK Score.

BACKGROUND: and aims: Cardiogenic shock (CS) remains the primary cause of in-hospital death after acute coronary syndromes (ACS), with its plateauing mortality rates approaching 50%. To test novel interventions, personalized risk prediction is essential. The ORBI (Observatoire Régional Breton sur l'Infarctus) score represents the first-of-its-kind risk score to predict in-hospital CS in ACS patients undergoing percutaneous coronary intervention (PCI). However, its sex-specific performance remains unknown, and refined risk prediction strategies are warranted. METHODS: This multinational study included a total of 53 537 ACS patients without CS on admission undergoing PCI. Following sex-specific evaluation of ORBI, regression and machine-learning models were used for variable selection and risk prediction. By combining best-performing models with highest-ranked predictors, SEX-SHOCK was developed, and internally and externally validated. RESULTS: The ORBI score showed lower discriminative performance for the prediction of CS in females than males in Swiss (AUC [95% CI]: 0.78 [0.76-0.81] vs. 0.81 [0.79-0.83]; p=0.048) and French ACS patients (0.77 [0.74-0.81] vs. 0.84 [0.81-0.86]; p=0.002). The newly developed SEX-SHOCK score, now incorporating ST-segment elevation, creatinine, C-reactive protein, and left ventricular ejection fraction, outperformed ORBI in both sexes (females: 0.81 [0.78-0.83]; males: 0.83 [0.82-0.85]; p<0.001), which prevailed following internal and external validation in RICO (females: 0.82 [0.79-0.85]; males: 0.88 [0.86-0.89]; p<0.001) and SPUM-ACS (females: 0.83 [0.77-0.90], p=0.004; males: 0.83 [0.80-0.87], p=0.001). CONCLUSIONS: The ORBI score showed modest sex-specific performance. The novel SEX-SHOCK score provides superior performance in females and males across the entire spectrum of ACS, thus providing a basis for future interventional trials and contemporary ACS management.

Proenkephalin Improves Cardio-Renal Risk Prediction in Acute Coronary Syndromes: The KID-ACS Score.

BACKGROUND AND AIMS: Circulating proenkephalin (PENK) is a stable endogenous polypeptide with fast response to glomerular dysfunction and tubular damage. This study examined the predictive value of PENK for renal outcomes and mortality in patients with acute coronary syndromes (ACS). METHODS: Proenkephalin was measured in plasma in a prospective multicentre ACS cohort from Switzerland (n=4787) and in validation cohorts from the UK (n=1141), Czechia (n=927), and Germany (n=220). A biomarker-enhanced risk score (KID-ACS score) for simultaneous prediction of in-hospital acute kidney injury (AKI) and 30-day mortality was derived and externally validated. RESULTS: On multivariable adjustment for established risk factors, circulating PENK remained associated with in-hospital AKI (per log2 increase: adjusted odds ratio [OR] 1.53, 95% confidence interval [CI] 1.13-2.09, P=0.007) and 30-day mortality (adjusted hazard ratio [HR] 2.73, 95% CI 1.85-4.02, P<0.001). The KID-ACS score integrates PENK and showed an area under the receiver operating characteristic curve (AUC) of 0.72 (95% CI 0.68-0.76) for in-hospital AKI, and of 0.91 (95% CI 0.87-0.95) for 30-day mortality in the derivation cohort. Upon external validation, KID-ACS achieved similarly high performance for in-hospital AKI (Zurich: AUC 0.73, 95% CI 0.70-0.77; Czechia: AUC 0.75, 95% CI 0.68-0.81; Germany: AUC 0.71, 95% CI 0.55-0.87) and 30-day mortality (UK: AUC 0.87, 95% CI 0.83-0.91; Czechia: AUC 0.91, 95% CI 0.87-0.94; Germany: AUC 0.96, 95% CI 0.92-1.00) outperforming the CA-AKI score and the GRACE 2.0 score, respectively. CONCLUSIONS: Circulating PENK offers incremental value for predicting in-hospital AKI and mortality in ACS. The simple 6-item KID-ACS risk score integrates PENK and provides a novel tool for simultaneous assessment of renal and mortality risk in patients with ACS.

Long-term outcomes with biodegradable polymer sirolimus-eluting stents versus durable polymer everolimus-eluting stents in ST-segment elevation myocardial infarction: 5-year follow-up of the BIOSTEMI randomised superiority trial.

BACKGROUND: Biodegradable polymer sirolimus-eluting stents improve early stent-related clinical outcomes compared to durable polymer everolimus-eluting stents in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention. The long-term advantages of biodegradable polymer sirolimus-eluting stents after complete degradation of its polymer coating in patients with STEMI remains however uncertain. METHODS: BIOSTEMI Extended Survival (BIOSTEMI ES) was an investigator-initiated, follow-up extension study of the BIOSTEMI prospective, multicentre, single-blind, randomised superiority trial that compared biodegradable polymer sirolimus-eluting stents with durable polymer everolimus-eluting stents in patients with STEMI undergoing primary percutaneous coronary intervention at ten hospitals in Switzerland. All individuals who had provided written informed consent for participation in the BIOSTEMI trial were eligible for this follow-up study. The primary endpoint was target lesion failure, defined as a composite of cardiac death, target vessel myocardial re-infarction, or clinically indicated target lesion revascularisation, at 5 years. Superiority of biodegradable polymer sirolimus-eluting stents over durable polymer everolimus-eluting stents was declared if the Bayesian posterior probability for a rate ratio (RR) of less than 1 was greater than 0·975. Analyses were performed according to the intention-to-treat principle. The study was registered with ClinicalTrials.gov, NCT05484310. FINDINGS: Between April 26, 2016, and March 9, 2018, 1300 patients with STEMI (1622 lesions) were randomly allocated in a 1:1 ratio to treatment with biodegradable polymer sirolimus-eluting stents (649 patients, 816 lesions) or durable polymer everolimus-eluting stents (651 patients, 806 lesions). At 5 years, the primary composite endpoint of target lesion failure occurred in 50 (8%) patients treated with biodegradable polymer sirolimus-eluting stents and in 72 (11%) patients treated with durable polymer everolimus-eluting stents (difference of -3%; RR 0·70, 95% Bayesian credible interval 0·51-0·95; Bayesian posterior probability for superiority 0·988). INTERPRETATION: In patients undergoing primary percutaneous coronary intervention for STEMI, biodegradable polymer sirolimus-eluting stents were superior to durable polymer everolimus-eluting stents with respect to target lesion failure at 5 years of follow-up. The difference was driven by a numerically lower risk for ischaemia-driven target lesion revascularisation. FUNDING: Biotronik.

Dual Antiplatelet Therapy after PCI in Patients at High Bleeding Risk.

BACKGROUND: The appropriate duration of dual antiplatelet therapy in patients at high risk for bleeding after the implantation of a drug-eluting coronary stent remains unclear. METHODS: One month after they had undergone implantation of a biodegradable-polymer sirolimus-eluting coronary stent, we randomly assigned patients at high bleeding risk to discontinue dual antiplatelet therapy immediately (abbreviated therapy) or to continue it for at least 2 additional months (standard therapy). The three ranked primary outcomes were net adverse clinical events (a composite of death from any cause, myocardial infarction, stroke, or major bleeding), major adverse cardiac or cerebral events (a composite of death from any cause, myocardial infarction, or stroke), and major or clinically relevant nonmajor bleeding; cumulative incidences were assessed at 335 days. The first two outcomes were assessed for noninferiority in the per-protocol population, and the third outcome for superiority in the intention-to-treat population. RESULTS: Among the 4434 patients in the per-protocol population, net adverse clinical events occurred in 165 patients (7.5%) in the abbreviated-therapy group and in 172 (7.7%) in the standard-therapy group (difference, -0.23 percentage points; 95% confidence interval [CI], -1.80 to 1.33; P<0.001 for noninferiority). A total of 133 patients (6.1%) in the abbreviated-therapy group and 132 patients (5.9%) in the standard-therapy group had a major adverse cardiac or cerebral event (difference, 0.11 percentage points; 95% CI, -1.29 to 1.51; P = 0.001 for noninferiority). Among the 4579 patients in the intention-to-treat population, major or clinically relevant nonmajor bleeding occurred in 148 patients (6.5%) in the abbreviated-therapy group and in 211 (9.4%) in the standard-therapy group (difference, -2.82 percentage points; 95% CI, -4.40 to -1.24; P<0.001 for superiority). CONCLUSIONS: One month of dual antiplatelet therapy was noninferior to the continuation of therapy for at least 2 additional months with regard to the occurrence of net adverse clinical events and major adverse cardiac or cerebral events; abbreviated therapy also resulted in a lower incidence of major or clinically relevant nonmajor bleeding.

Routine beta-blocker therapy after acute coronary syndromes: The end of an era?

BACKGROUND: Beta-blocker therapy, a treatment burdened by side effects including fatigue, erectile dysfunction and depression, was shown to reduce mortality and cardiovascular events after acute coronary syndromes (ACS) in the pre-coronary reperfusion era. Potential mechanisms include protection from ventricular arrhythmias, increased ischaemia threshold and prevention of left ventricular (LV) adverse remodelling. With the advent of early mechanical reperfusion and contemporary pharmacologic secondary prevention, the benefit of beta-blockers after ACS in the absence of LV dysfunction has been challenged. METHODS: The present narrative review discusses the contemporary evidence based on searching the PubMed database and references in identified articles. RESULTS: Recently, the REDUCE-AMI trial-the first adequately powered randomized trial in the reperfusion era to test beta-blocker therapy after myocardial infarction with preserved left ventricular ejection fraction (LVEF)-showed no benefit on the composite of all-cause death or myocardial infarction over a median 3.5-year follow-up. While the benefit of beta-blockers in patients with reduced LVEF remains undisputed, their value in post-ACS patients with mildly reduced systolic function (LVEF 41%-49%) has not been studied in contemporary randomized trials; in this setting, observational studies have suggested a reduction in cardiovascular events with these agents. The adequate duration of beta-blocker therapy remains unknown, but observational data suggests that any mortality benefit may be lost beyond 1-12 months after ACS in patients with LVEF >40%. CONCLUSION: We believe that there is sufficient evidence to abandon routine beta-blocker prescription in post-ACS patients with preserved LV systolic function.

Applicability of European Society of Cardiology guidelines according to gross national income.

AIMS: To assess the feasibility to comply with the recommended actions of ESC guidelines on general cardiology areas in 102 countries and assess how compliance relates to the country's income level. METHODS AND RESULTS: All recommendations from seven ESC guidelines on general cardiology areas were extracted and labelled on recommended actions. A survey was sent to all 102 ESC national and affiliated cardiac societies (NCSs). Respondents were asked to score recommended actions on their availability in clinical practice on a four-point Likert scale (fully available, mostly/often available, mostly/often unavailable, fully unavailable), and select the top three barriers perceived as being responsible for limiting their national availability. Applicability was assessed overall, per World Bank gross national income (GNI) level, and per guideline.A total of 875 guideline recommendations on general cardiology was extracted. Responses were received from 64 of 102 (62.7%) NCSs. On average, 71·6% [95% confidence interval (CI): 68.6-74.6] of the actions were fully available, 9.9% (95% CI: 8.7-11.1) mostly/often available, 6.7% (95% CI: 5.4-8.0) mostly/often unavailable, and 11·8% (95% CI: 9.5-14.1) fully unavailable. In low-income countries (LICs), substantially more actions were fully unavailable [29·4% (95% CI: 22.6-36.3)] compared with high-income countries [HICs, countries 2.4% (95% CI: 1.2-3.7); P < 0.05]. Nevertheless, a proportion of actions with the lowest availability scores were often fully or mostly unavailable independent of GNIs. Actions were most often not available due to lack of reimbursement and other financial barriers. CONCLUSION: Local implementation of ESC guidelines on general cardiology is high in HICs and low in LICs , being inversely correlated with country gross national incomes.

Dipeptidyl peptidase 3 plasma levels predict cardiogenic shock and mortality in acute coronary syndromes.

BACKGROUND AND AIMS: Dipeptidyl peptidase 3 (DPP3) is a protease involved in the degradation of angiotensin II which disturbs peripheral blood pressure regulation and compromises left ventricular function. This study examined the relationship of circulating DPP3 (cDPP3) with cardiogenic shock (CS) and mortality in patients presenting with acute coronary syndromes (ACS). METHODS: Plasma cDPP3 levels were assessed at baseline and 12-24 h after presentation in patients with ACS prospectively enrolled into the multi-centre SPUM-ACS study (n = 4787). RESULTS: Circulating DPP3 levels were associated with in-hospital CS when accounting for established risk factors including the ORBI risk score [per log-2 increase, hazard ratio (HR) 1.38, 95% confidence interval (CI) 1.05-1.82, P = .021]. High cDPP3 was an independent predictor of mortality at 30 days (HR 1.87, 95% CI 1.36-2.58, P < .001) and at one year (HR 1.61, 95% CI 1.28-2.02, P < .001) after adjustment for established risk factors and the GRACE 2.0 score. Compared to values within the normal range, persistently elevated cDPP3 levels at 12-24 h were associated with 13.4-fold increased 30-day mortality risk (HR 13.42, 95% CI 4.86-37.09, P < .001) and 5.8-fold increased 1-year mortality risk (HR 5.79, 95% CI 2.70-12.42, P < .001). Results were consistent across various patient subgroups. CONCLUSIONS: This study identifies cDPP3 as a novel marker of CS and increased mortality in patients with ACS. Circulating DPP3 offers prognostic information beyond established risk factors and improves early risk assessment.

[Management of acute coronary syndromes 2023 European Society of Cardiology guidelines]. / Prise en charge du syndrome coronarien aigu. Recommandations 2023 de la Société européenne de cardiologie.

For the first time, the European Society of Cardiology has drafted guidelines which encompass the management of the entire spectrum of patients with acute coronary syndrome, ranging from cardiogenic shock or cardiac arrest to ST-segment as well as non-ST-segment elevation myocardial infarction, to unstable angina. Some of the modified, as well as new recommendations include cardiac arrest, cardiogenic shock, diagnostic workup, antithrombotic therapy, timing of invasive strategy, intravascular imaging and revascularization in multivessel coronary artery disease. In addition, and for the first time, one entire section is dedicated to the patient's perspective and shared decision.

Pour la première fois, la Société européenne de cardiologie a regroupé dans un seul document les recommandations concernant la totalité des syndromes coronariens aigus, englobant l'angor instable, l'infarctus du myocarde avec ou sans sus-décalage du segment ST à l'électrocardiogramme, le choc cardiogène ou l'arrêt cardiaque. Nous détaillons ici quelques modifications et nouvelles recommandations concernant le bilan diagnostique, le moment de la stratégie invasive, la revascularisation en cas de maladie coronarienne pluritronculaire, l'imagerie intravasculaire, l'arrêt cardiaque, le choc cardiogène et le traitement antithrombotique. De plus, pour la première fois, les perspectives des patients font partie intégrante du document, les impliquant notamment dans le processus décisionnel.

[False positive on macrotroponin]. / Faux positif lié à une macrotroponinémie élevée.

The determination of I and T subunits of cardiac troponin isoforms are the biochemical gold standard for the detection of myocardial distress. The advent of so-called highly sensitive measurements has optimized the diagnosis of acute coronary syndromes at the cost of making the diagnostic approach more complex and increasing sensitivity to analytical interference. This article presents a case of macrotroponinemia, characterized by circulating IgG-troponin T immunocomplexes, in order to raise prescribers' awareness of the critical interpretation of high and persistent cardiac troponin values.

Le dosage des sous-unités I et T des isoformes cardiaques de troponines est le gold-standard biochimique de la détection de la souffrance myocardique. L'avènement des mesures dites hautement sensibles a optimisé le diagnostic des syndromes coronariens aigus au prix d'une complexification de la démarche diagnostique et d'une sensibilité accrue aux interférences analytiques. Cet article présente un cas de macrotroponinémie, caractérisé par des immunocomplexes IgG-troponine T circulants, afin de sensibiliser les prescripteurs à l'interprétation critique des valeurs élevées et persistantes de troponines cardiaques (cTn).

[Vasospastic angina : an underdiagnosed pathology]. / Vasospasme coronarien : une pathologie sous-diagnostiquée.

Vasospastic angina (VSA) was first described in 1959 by Myron Prinzmetal as "the variant form of angina pectoris" on the sole basis of medical history and ECG. This condition is currently categorized as an endotype of myocardial infarction without coronary obstruction (Myocardial Infarction with Non-Obstructive Coronary Arteries (MINOCA)). Diagnostic criteria have been suggested by expert consensus. Provocative testing during coronary angiography is the gold standard test but is rarely used. The clinical presentation is often neglected, and the diagnosis is missed. However, VSA may lead to life-threatening arrhythmias. There are simple and effective therapies that are markedly different from those for the atherosclerotic coronary artery disease.

Le vasospasme coronarien (VC) a été décrit pour la première fois en 1959 par Myron Prinzmetal comme « la forme variante de l'angine de poitrine ¼ sur la seule base de l'anamnèse et de l'ECG. Le VC est actuellement classé comme un endotype de l'infarctus du myocarde sans obstruction coronaire (Myocardial Infarction with Non-Obstructive Coronary Arteries (MINOCA)). Des critères diagnostiques ont été proposés par des consensus d'experts. Le test de provocation lors de la coronarographie est l'examen de choix mais est rarement employé. La symptomatologie est souvent méconnue et le diagnostic n'est pas suffisamment évoqué. Pourtant, le VC peut conduire à des arythmies potentiellement fatales. Nous disposons de moyens thérapeutiques simples et efficaces, qui diffèrent sensiblement de ceux de la maladie coronarienne athérosclérotique.

Sex-specific evaluation and redevelopment of the GRACE score in non-ST-segment elevation acute coronary syndromes in populations from the UK and Switzerland: a multinational analysis with external cohort validation.

BACKGROUND: The Global Registry of Acute Coronary Events (GRACE) 2.0 score was developed and validated in predominantly male patient populations. We aimed to assess its sex-specific performance in non-ST-segment elevation acute coronary syndromes (NSTE-ACS) and to develop an improved score (GRACE 3.0) that accounts for sex differences in disease characteristics. METHODS: We evaluated the GRACE 2.0 score in 420 781 consecutive patients with NSTE-ACS in contemporary nationwide cohorts from the UK and Switzerland. Machine learning models to predict in-hospital mortality were informed by the GRACE variables and developed in sex-disaggregated data from 386 591 patients from England, Wales, and Northern Ireland (split into a training cohort of 309 083 [80·0%] patients and a validation cohort of 77 508 [20·0%] patients). External validation of the GRACE 3.0 score was done in 20 727 patients from Switzerland. FINDINGS: Between Jan 1, 2005, and Aug 27, 2020, 400 054 patients with NSTE-ACS in the UK and 20 727 patients with NSTE-ACS in Switzerland were included in the study. Discrimination of in-hospital death by the GRACE 2.0 score was good in male patients (area under the receiver operating characteristic curve [AUC] 0·86, 95% CI 0·86-0·86) and notably lower in female patients (0·82, 95% CI 0·81-0·82; p<0·0001). The GRACE 2.0 score underestimated in-hospital mortality risk in female patients, favouring their incorrect stratification to the low-to-intermediate risk group, for which the score does not indicate early invasive treatment. Accounting for sex differences, GRACE 3.0 showed superior discrimination and good calibration with an AUC of 0·91 (95% CI 0·89-0·92) in male patients and 0·87 (95% CI 0·84-0·89) in female patients in an external cohort validation. GRACE 3·0 led to a clinically relevant reclassification of female patients to the high-risk group. INTERPRETATION: The GRACE 2.0 score has limited discriminatory performance and underestimates in-hospital mortality in female patients with NSTE-ACS. The GRACE 3.0 score performs better in men and women and reduces sex inequalities in risk stratification.

Ultrathin-strut vs thin-strut drug-eluting stents for multi and single-stent lesions: A lesion-level subgroup analysis of 2 randomized trials.

BACKGROUND: Whether ultrathin-strut stents are particularly beneficial for lesions requiring implantation of more than 1 stent is unknown. METHODS: In a post-hoc lesion-level analysis of 2 randomized trials comparing ultrathin-strut biodegradable polymer Sirolimus-eluting stents (BP-SES) vs thin-strut durable polymer Everolimus-eluting stents (DP-EES), lesions were stratified into multistent lesions (MSL) vs single-stent lesions (SSL). The primary endpoint was target lesion failure (TLF), a composite of lesion-related unclear/cardiac death, myocardial infarction (MI), or revascularization, at 24 months. RESULTS: Among 5328 lesions in 3397 patients, 1492 (28%) were MSL (722 with BP-SES, 770 with DP-EES). At 2 years, TLF occurred in 63 lesions (8.9%) treated with BP-SES and 60 lesions (7.9%) treated with DP-EES in the MSL-group (subdistibution hazard ratio [SHR], 1.13; 95% CI, 0.77-1.64; P = .53), and in 121 (6.4%) and 136 (7.4%) lesions treated with BP-SES and DP-EES respectively (SHR, 0.86; 95% CI, 0.62-1.18; P = .35) in the SSL-group (P for interaction = .241). While the rates of lesion-related MI or revascularization were significantly lower in SSL treated with BP-SES as compared to DP-EES (3.5% vs 5.2%; SHR, 0.67; 95% CI 0.46-0.97; P = .036), no significant difference was observed in MSL (7.1% vs 5.4%; SHR, 1.31; 95% CI 0.85-2.03; P = .216) with significant interaction between groups (P for interaction = .014). CONCLUSIONS: Rates of TLF are similar between ultrathin-strut BP-SES and thin-strut DP-EES in MSL and SSL. The use of ultrathin-strut BP-SES vs thin-strut DP-EES did not prove to be particularly beneficial for the treatment of multistent lesions. TRIAL REGISTRATION: Post-hoc analysis from the BIOSCIENCE (NCT01443104) and BIOSTEMI (NCT02579031) trials.

Complementary evidence on the performance of coronary stents generated by a randomized controlled trial and a worldwide registry.

BACKGROUND: Large-scale registries can provide valuable complementary data to randomized controlled trials (RCT) for the postmarketing evaluation of coronary stents, but their scientific relevance remains debated. METHODS: We sought to compare the evidence on the performance of a single coronary stent platform generated by the RCT for its regulatory approval and a well-conducted international registry. Patients treated with the Ultimaster coronary stent in the CENTURY II (CII-UM) trial (n = 551) were compared to patients in the real-world e-ULTIMASTER (e-UM) registry (n = 35,389). All major events were adjudicated by an independent clinical event committee in both studies. Propensity weighted analysis was used to balance baseline and procedural differences between the 2 populations. RESULTS: Coronary artery disease was more complex in e-UM compared to CII-UM, including more acute coronary syndromes, multivessel disease, left main, arterial, or venous grafts, and chronic total occlusions (P < .005 for all). At one-year follow-up and after excluding periprocedural myocardial infarction (MI) there was no statistically significant difference between CII-UM and e-UM regarding all-cause death (hazard ratio [HR] 0.55, 95% confidence interval [CI] 0.26-1.20, P = .14), cardiac death (HR 0.71, 95% CI 0.29-1.72, P = .45), target lesion failure (HR 1.18, 95% CI 0.78-1.78, P = .44), and target vessel MI (HR 0.76, 95% CI 0.24-2.38, P = .63). However, target vessel revascularization rate was significantly higher in CII-UM than in e-UM, HR 1.78, 95% CI 1.23-2.56, P = .002. CONCLUSIONS: A well-conducted large-scale registry can provide valuable complementary evidence to RCTs on the postmarket performance of new coronary stents, across a wider range of uses and various geographic areas.

Complex primary percutaneous coronary intervention with ultrathin-strut biodegradable versus thin-strut durable polymer drug-eluting stents in patients with ST-segment elevation myocardial infarction: A subgroup analysis from the BIOSTEMI randomized trial.

BACKGROUND: Ultrathin-strut biodegradable polymer sirolimus-eluting stents (BP-SES) are superior to thin-strut durable polymer everolimus-eluting stents (DP-EES) with respect to target lesion failure (TLF) at 2 years among patients with ST-segment elevation myocardial infarction (STEMI). We sought to determine the impact of primary percutaneous coronary intervention (pPCI) complexity on long-term clinical outcomes with BP-SES versus DP-EES in STEMI patients. METHODS: We performed a post hoc subgroup analysis from the BIOSTEMI (NCT02579031) randomized trial, which included individual data from 407 STEMI patients enrolled in the BIOSCIENCE trial (NCT01443104). STEMI patients were randomly assigned to treatment with ultrathin-strut BP-SES or thin-strut DP-EES, and further categorized into those undergoing complex versus noncomplex pPCI. Complex pPCI was defined by the presence of ≥1 of the following criteria: 3 vessel treatment, ≥3 stents implanted, ≥3 lesions treated, bifurcation lesion with ≥2 stents implanted, total stent length ≥60 mm, and/or chronic total occlusion treatment. The primary endpoint was TLF, a composite of cardiac death, target-vessel myocardial reinfarction, or clinically indicated target lesion revascularization, within 2 years. RESULTS: Among a total of 1707 STEMI patients, 421 (24.7%) underwent complex pPCI. Baseline characteristics were similar between groups. At 2 years, TLF occurred in 14 patients (7.1%) treated with BP-SES and 25 patients (11.6%) treated with DP-EES (hazard ratio [HR]: 0.62; 95% confidence interval [CI]: 0.32-1.19; p = 0.15) in the complex pPCI group, and in 28 patients (4.4%) treated with BP-SES and 49 patients (8.2%) treated with DP-EES (HR: 0.54; 95% CI: 0.34-0.86; p = 0.008; p for interaction = 0.74) in the noncomplex pPCI group. Individual TLF components and stent thrombosis rates did not significantly differ between groups. CONCLUSION: In a post hoc subgroup analysis from the BIOSTEMI randomized trial, ultrathin-strut BP-SES were superior to thin-strut DP-EES with respect to TLF at 2 years among STEMI patients undergoing both complex and noncomplex pPCI.

[Challenges of coronary revascularization in diabetic patients in 2023]. / Défis de la revascularisation coronarienne du patient diabétique en 2023.

Diabetic patients remain at increased risk for major adverse cardiovascular events, compared to their non-diabetic counterparts. Coronary artery bypass grafting remains superior to percutaneous coronary intervention (PCI) among diabetic patients with chronic coronary syndrome and multivessel coronary artery disease. PCI represents an alternative in diabetic patient with low coronary anatomy complexity. The revascularization strategy should be discussed by a multidisciplinary Heart Team. Despite advances in DES technology, PCI in diabetic patients remains associated with a higher risk of adverse outcomes than in non-diabetic patients, but the long-term outcome results from recently published and ongoing large-scale randomized studies investigating novel DES designs may reshape the landscape of coronary revascularization for diabetic patient.

Les patients diabétiques présentent plus d'événements cardiovasculaires (CV) majeurs que les non diabétiques. Le pontage aortocoronarien reste supérieur à l'angioplastie chez les patients diabétiques avec une maladie coronarienne pluritronculaire stable. L'angioplastie coronarienne percutanée constitue une alternative en cas d'anatomie coronarienne peu complexe. La revascularisation chez ces patients doit être discutée en équipe multidisciplinaire. Malgré les progrès des stents à élution médicamenteuse (DES) de dernière génération, l'angioplastie percutanée reste associée à plus d'événements CV chez les patients diabétiques, mais les résultats du suivi à long terme d'essais randomisés, récemment publiés ou en cours, évaluant de nouvelles technologies de DES, pourraient modifier le panorama de la revascularisation du patient diabétique.

Abbreviated Antiplatelet Therapy in Patients at High Bleeding Risk With or Without Oral Anticoagulant Therapy After Coronary Stenting: An Open-Label, Randomized, Controlled Trial.

BACKGROUND: The optimal duration of antiplatelet therapy (APT) in patients at high bleeding risk with or without oral anticoagulation (OAC) after coronary stenting remains unclear. METHODS: In the investigator-initiated, randomize, open-label MASTER DAPT trial (Management of High Bleeding Risk Patients Post Bioresorbable Polymer Coated Stent Implantation With an Abbreviated Versus Standard DAPT Regimen), 4579 patients at high bleeding risk were randomized after 1-month dual APT to abbreviated or nonabbreviated APT strategies. Randomization was stratified by concomitant OAC indication. In this subgroup analysis, we report outcomes of populations with or without an OAC indication. In the population with an OAC indication, patients changed immediately to single APT for 5 months (abbreviated regimen) or continued ≥2 months of dual APT and single APT thereafter (nonabbreviated regimen). Patients without an OAC indication changed to single APT for 11 months (abbreviated regimen) or continued ≥5 months of dual APT and single APT thereafter (nonabbreviated regimen). Coprimary outcomes at 335 days after randomization were net adverse clinical outcomes (composite of all-cause death, myocardial infarction, stroke, and Bleeding Academic Research Consortium 3 or 5 bleeding events); major adverse cardiac and cerebral events (all-cause death, myocardial infarction, and stroke); and type 2, 3, or 5 Bleeding Academic Research Consortium bleeding. RESULTS: Net adverse clinical outcomes or major adverse cardiac and cerebral events did not differ with abbreviated versus nonabbreviated APT regimens in patients with OAC indication (n=1666; hazard ratio [HR], 0.83 [95% CI, 0.60-1.15]; and HR, 0.88 [95% CI, 0.60-1.30], respectively) or without OAC indication (n=2913; HR, 1.01 [95% CI, 0.77-1.33]; or HR, 1.06 [95% CI, 0.79-1.44]; Pinteraction=0.35 and 0.45, respectively). Bleeding Academic Research Consortium 2, 3, or 5 bleeding did not significantly differ in patients with OAC indication (HR, 0.83 [95% CI, 0.62-1.12]) but was lower with abbreviated APT in patients without OAC indication (HR, 0.55 [95% CI, 0.41-0.74]; Pinteraction=0.057). The difference in bleeding in patients without OAC indication was driven mainly by a reduction in Bleeding Academic Research Consortium 2 bleedings (HR, 0.48 [95% CI, 0.33-0.69]; Pinteraction=0.021). CONCLUSIONS: Rates of net adverse clinical outcomes and major adverse cardiac and cerebral events did not differ with abbreviated APT in patients with high bleeding risk with or without an OAC indication and resulted in lower bleeding rates in patients without an OAC indication.

Antithrombotic therapies in aortic and peripheral arterial diseases in 2021: a consensus document from the ESC working group on aorta and peripheral vascular diseases, the ESC working group on thrombosis, and the ESC working group on cardiovascular pharmacotherapy.

The aim of this collaborative document is to provide an update for clinicians on best antithrombotic strategies in patients with aortic and/or peripheral arterial diseases. Antithrombotic therapy is a pillar of optimal medical treatment for these patients at very high cardiovascular risk. While the number of trials on antithrombotic therapies in patients with aortic or peripheral arterial diseases is substantially smaller than for those with coronary artery disease, recent evidence deserves to be incorporated into clinical practice. In the absence of specific indications for chronic oral anticoagulation due to concomitant cardiovascular disease, a single antiplatelet agent is the basis for long-term antithrombotic treatment in patients with aortic or peripheral arterial diseases. Its association with another antiplatelet agent or low-dose anticoagulants will be discussed, based on patient's ischaemic and bleeding risk as well therapeutic paths (e.g. endovascular therapy). This consensus document aims to provide a guidance for antithrombotic therapy according to arterial disease localizations and clinical presentation. However, it cannot substitute multidisciplinary team discussions, which are particularly important in patients with uncertain ischaemic/bleeding balance. Importantly, since this balance evolves over time in an individual patient, a regular reassessment of the antithrombotic therapy is of paramount importance.

Interdisciplinary management of acute ischaemic stroke: Current evidence training requirements for endovascular stroke treatment. Position Paper from the ESC Council on Stroke and the European Association for Percutaneous Cardiovascular Interventions with the support of the European Board of Neurointervention.

This ESC Council on Stroke/EAPCI/EBNI position paper summarizes recommendations for training of cardiologists in endovascular treatment of acute ischaemic stroke. Interventional cardiologists adequately trained to perform endovascular stroke interventions could complement stroke teams to provide the 24/7 on call duty and thus to increase timely access of stroke patients to endovascular treatment. The training requirements for interventional cardiologists to perform endovascular therapy are described in details and should be based on two main principles: (i) patient safety cannot be compromised, (ii) proper training of interventional cardiologists should be under supervision of and guaranteed by a qualified neurointerventionist and within the setting of a stroke team. Interdisciplinary cooperation based on common standards and professional consensus is the key to the quality improvement in stroke treatment.

[Cardiac surgery in the time of COVID19 - A narrative of three very unusual cases and lessons learned]. / Chirurgie cardiaque au temps du Covid-19 - Récit de trois cas très inhabituels et leçons retenues.

COVID19 altered and impacted medical and surgical practice around the world. Standard of care and routine procedures are disrupted. Majors shift in personnel, and ad hoc new team as well as delocalization and working with new infrastructures are further challenges to be dealt with. This review of three very unusual scenarios illustrates pitfalls and dangers harbored in the re-shaped landscape of COVID19 exemplifying the narrow path bridging from the medical and surgical comfort zone to uncharted territory and eventually leading to collateral damage.

Le Covid-19 a profondément modifié et sévèrement impacté les pratiques médicales et chirurgicales à long terme. Les standards de prise en charge et les procédures de routine sont altérés, voire perturbés. Des mutations majeures au niveau du personnel et des équipes de même que la délocalisation ou le travail avec de nouvelles infrastructures sont autant de défis à relever, encore aujourd'hui. Trois scénarios inhabituels illustrent les pièges et les dangers qui se cachent dans le paysage marqué par le Covid-19. Ces exemples démontrent la marge étroite entre la zone de confort médicale et chirurgicale classique et l'appréhension d'une situation inhabituelle qui risque d'entraîner des dommages collatéraux pour les patients.

Temporal trends in cardiovascular risk factors' prevalence in patients with myocardial infarction.

INTRODUCTION AND OBJECTIVES: Little is known about changes in cardiovascular risk factors (CVRF) profile over time in patients presenting with acute myocardial infarction (AMI). METHODS: We assessed changes in age and CVRF profile in consecutive AMI patients enrolled in the Swiss nationwide AMIS Plus registry between 1 January 1997 and 31 December 2018. RESULTS: A total of 57 995 AMI patients were included in the analysis. Mean age at presentation was 71.5 ± 11.3 years for women and 63.9 ± 12.8 years for men and did not change over time. Overall, the mean (standard deviation) number of CVRF increased from 1.76 (1.07) in 1997/98 to 2.26 (1.10) in 2017/18 in men (Ptrend  < .001), while the corresponding rates in females were 1.83 (1.11) and 2.24 (1.08) (Ptrend  < .001). In terms of active smoking, no significant trend was detected for males, while there was a significant increase in females (P < .001). As a result, the gap in smoking rates between men and women presenting with AMI decreased from 19.9% (45.3% vs 25.4%) in 1997/98 to 7.9% (41.2% vs 33.3%) in 2017/18. Reassuring was the stability in terms of diabetes prevalence for both genders. Obesity was more prevalent over time in men, while the prevalence of hypertension and dyslipidemia increased in both genders. CONCLUSION: Among patients with AMI in Switzerland over two decades, age at presentation remained stable, while the mean number of CVRF increased in both men and women. Striking was the increase in the prevalence of smoking in women, leading to a reduction of the gender gap over time.
