RESUMEN
Multivessel coronary artery disease (MVD) is a frequently encountered condition in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI) of the culprit vessel. Several studies have demonstrated the benefit of complete coronary revascularization compared with the treatment of the culprit lesion only in patients with STEMI. Based on this evidence, the current European guidelines recommend that in haemodynamically stable patients with STEMI and MVD, routine complete revascularization should be achieved either during the same procedure in concomitance with the treatment of the culprit lesion (immediate multivessel PCI) or with a subsequent intervention within 45 days from the index PCI of the culprit lesion (deferred multivessel PCI). However, the guidelines do not express a preference for immediate vs. delayed multivessel PCI. Therefore, the optimal timing of the treatment of non-culprit lesions in patients with STEMI and haemodynamic stability is still debated and has been evaluated in recent studies that showed the non-inferiority of immediate vs. delayed multivessel PCI. The article discusses the results and clinical implications of these studies on the timing of complete revascularization of non-culprit lesions in haemodynamically stable patients with STEMI.
RESUMEN
BACKGROUND: Frailty and comorbidity influence the therapeutic approach in everyday clinical practice. The DOACs genericization opens a reflection on their differences from a pharmacological and bioavailability point of view, particularly in elderly frail patients. The aim of this project was to create a national Delphi consensus on the topic of the use of DOACs for atrial fibrillation (AF) in such patients, in light of the genericization of the class. METHODS AND RESULTS: The consensus dealt with 3 main topics: a) efficacy and safety of DOACs in elderly and/or frail patients; b) therapeutic choice in specific frailty scenarios; c) DOACs genericization. 56 cardiologists, two internists and two neurologists from Italy expressed their level of agreement on each statement by using a 5-point Likert scale (1: strongly disagree, 2: disagree, 3: uncertain, 4: agree, 5: strongly agree). A positive consensus was reached if the percentage of agreement (vote 1-2, positive consensus) or disagreement (votes 4-5, negative consensus) was >66%; otherwise, no consensus was reached. Results are displayed accordingly. CONCLUSIONS: After 10 years of everyday clinical management of DOACs for AF, specific elements differentiating a molecule from another, either for efficacy or for safety, are consolidated. However, some uncertainties still exist in particular contexts, such as chronic kidney disease or cancer patients. Clinicians have an unsure attitude towards generic drugs, because clinical practice is lacking as well as a proper knowledge of the topic. Albeit being an alternative, the choice of the generic drug must remain the responsibility of the clinician.

INTRODUCTION: The potential benefit on long term outcomes of Percutaneous Coronary Intervention (PCI) on Unprotected Left Main (ULM) driven by IntraVascular UltraSound (IVUS) remains to be defined. METHODS: IMPACTUS LM-PCI is an observational, multicenter study that enrolled consecutive patients with ULM disease undergoing coronary angioplasty in 13 European high-volume centers from January 2002 to December 2015. Major Adverse Cardiovascular Events (MACEs) a composite of cardiovascular (CV) death, target vessel revascularization (TVR) and myocardial infarction (MI) were the primary endpoints, while its single components along with all cause death the secondary ones. RESULTS: 627 patients with ULM disease were enrolled, 213 patients (34%) underwent IVUS-guided PCI while 414 (66%) angioguided PCI. Patients in the two cohorts had similar prevalence of risk factors except for active smoking and clinical presentation. During a median follow-up of 7.5 years, 47 (22%) patients in the IVUS group and 211 (51%) in the angio-guided group underwent the primary endpoint (HR 0.42; 95% CI [0.31-0.58] p < 0.001). After multivariate adjustment, IVUS was significantly associated with a reduced incidence of the primary endpoint (adj HR 0.39; 95% CI [0.23-0.64], p < 0.001), mainly driven by a reduction of TVR (ad HR 0.30, 95% CI [0.15-0.62], p = 0.001) and of all-cause death (adj HR 0.47, 95% CI [0.28-0.82], p = 0.008). IVUS use, age, diabetes, side branch stenosis, DES and creatinine at admission were independent predictors of MACE. CONCLUSIONS: In patients undergoing ULM PCI, the use of IVUS was associated with a reduced risk at long-term follow-up of MACE, all-cause death and subsequent revascularization.

Background: There are limited data to assess pharmacodynamic (PD) profiles of patients with STEMI undergoing primary percutaneous coronary intervention (PCI) and receiving cangrelor after pretreatment with ticagrelor. Methods: The PharmacOdynaMic effects of cangrelor in PatiEnts wIth acute or chronIc coronary syndrome undergoing percutaneous coronary intervention (POMPEII) registry (NCT04790032) is a prospective study conducted at Federico II University of Naples enrolling all patients undergoing PCI receiving cangrelor at operator's discretion. PD assessments were performed with 3 assays: (1) the gold standard light transmittance aggregometry (LTA) (20- and 5-µM adenosine diphosphate [ADP] stimuli); (2) VerifyNow P2Y12-test; (3) Multiplate electrode aggregometry (MEA), ADP-test. Results: We analyzed 13 STEMI patients pretreated with ticagrelor within 1 h at the time they underwent primary PCI receiving cangrelor. All patients showed low maximal platelet aggregation at 30-minute during cangrelor infusion, as well as at 3 h and 4-6 h (corresponding to 1 h and 2-4 h after stopping cangrelor infusion) with no cases of high residual platelet reactivity. These results were consistent with all assays. Conclusions: PD data show that in contemporary real-world STEMI patients pretreated within 1 h with ticagrelor undergoing primary PCI, adding cangrelor resulted in fast and potent platelet inhibition, thus suggesting that cangrelor may bridge the gap until ticagrelor reaches its effect.
RESUMEN
BACKGROUND: Whether P2Y12 inhibitor monotherapy (P2Y12-I) is superior to aspirin following DAPT discontinuation post-PCI remains to be established. METHODS: We updated our prior network meta-analysis where P2Y12-I and aspirin had been compared with DAPT or directly with each other. The focus is specifically on the available direct evidence, now consisting of the three head-to-head comparisons of P2Y12-I and aspirin in event-free PCI patients after DAPT. We include a Trial Sequential Analysis of the direct evidence based on meta-analytical literature. RESULTS: The main finding reveals a 39% significantly lower risk of myocardial infarction with P2Y12-I (RR 0.61, 95% CI 0.47-0.78, p = 0.0001, I2 = 0%) with no difference in bleeding. Trial Sequential Analysis demonstrates clinically meaningful evidence for a reduction in the incidence of myocardial infarction with P2Y12-I that is also supported by statistical significance. CONCLUSIONS: Accruing data highlight that P2Y12-I following DAPT discontinuation after PCI is associated with lower risk for MI and a similar risk for bleeding as compared with ASA. In light of potential limitations to the widespread adoption of life-long P2Y12-I treatment, clinicians should consider identifying selected patients who are expected to derive the highest benefit.

Dual antiplatelet therapy (DAPT) with aspirin and a platelet P2Y12 receptor inhibitor is the standard antithrombotic treatment after percutaneous coronary interventions (PCI). Several trials have challenged guideline-recommended DAPT after PCI by testing the relative clinical effect of an aspirin-free antiplatelet approach-consisting of P2Y12 inhibitor monotherapy after a short course (mostly 1-3 months) of DAPT-among patients undergoing PCI without a concomitant indication for oral anticoagulation (OAC). Overall, these studies have shown P2Y12 inhibitor monotherapy after short DAPT to be associated with a significant reduction in the risk of bleeding without an increase in thrombotic or ischaemic events compared with continued DAPT. Moreover, the effects of the P2Y12 inhibitor monotherapy without prior DAPT or following a very short course of DAPT after PCI are being investigated in emerging studies, of which one has recently reported unfavourable efficacy results associated with the aspirin-free approach compared with conventional DAPT. Finally, P2Y12 inhibitor alone has been compared with aspirin alone as chronic therapy after DAPT discontinuation, thus challenging the historical role of aspirin as a standard of care for secondary prevention following PCI. A thorough understanding of study designs, populations, treatments, results, and limitations of trials testing P2Y12 inhibitor monotherapy vs. DAPT or vs. aspirin is required to consider adopting this treatment in clinical practice. This review addresses the use of aspirin-free antiplatelet strategies among patients undergoing PCI without a concomitant indication for OAC, providing an overview of clinical evidence, guideline indications, practical implications, ongoing issues, and future perspectives.

BACKGROUND: The risks of prefrail and frail women undergoing transcatheter aortic valve replacement (TAVR) have not been fully examined. The aim of the analysis was to assess the prognostic impact of prefrailty and frailty in women undergoing TAVR. METHODS: Women at intermediate or high surgical risk with severe aortic stenosis undergoing TAVR from the prospective multicentre WIN-TAVI (Women's International Transcatheter Aortic Valve Implantation) registry were stratified based on the number of Fried frailty criteria (weight loss, exhaustion, low physical activity, slow gait, weakness) met: nonfrail (no criteria), prefrail (1 or 2 criteria), or frail (3 or more criteria). The primary outcome at 1 year was the Valve Academic Research Consortium 2 (VARC-2) efficacy end point, a composite of mortality, stroke, myocardial infarction, hospitalisation for valve-related symptoms or heart failure, and valve-related dysfunction; secondary outcomes included the composite of VARC-2 life-threatening or major bleeding. RESULTS: Out of 1019 women, 297 (29.1%) met at least 1 frailty criterion: 264 (25.9%) had prefrailty and 33 (3.2%) frailty. The 1-year risk of the primary outcome was significantly higher in prefrail and frail (20.2%) than in nonfrail (14.9%) women (adjusted hazard ratio [aHR] 1.51, 95% confidence interval [CI] 1.07-2.12). The risk of VARC-2 life-threatening or major bleeding was higher in prefrail or frail (19.9%) than in nonfrail (10.0%) women (aHR 2.06, 95% CI 1.42-2.97). These risks were consistently increased in the prefrail and frail groups assessed separately. CONCLUSIONS: In women undergoing TAVR, the presence of prefrailty or frailty conferred an increased risk of the VARC-2 efficacy end point and of VARC-2 life-threatening or major bleeding.

Aims: Cangrelor is the only intravenous P2Y12 inhibitor available. Safety, efficacy, and transitioning from cangrelor to oral P2Y12 inhibitors were recorded in patients with acute coronary syndrome (ACS). The ARCANGELO study aims to assess the safety of cangrelor on bleeding and the effects of the transition to oral P2Y12 inhibitors in a real-world setting according to the European Medical Agency's requirement. Methods and results: Adult patients with ACS undergoing percutaneous coronary intervention (PCI) receiving cangrelor were included in the study. Patients were followed for 30 days. Incidence of bleeding events, major adverse cardiac events, and transition strategy to oral P2Y12 were recorded. Among 1004 ACS patients undergoing PCI, 995 (99.1%) were eligible for the analysis; 597 (60.0%) of them had ST-segment elevation myocardial infarction. A total of 925 (93.1%) patients underwent PCI by radial catheter access, and 972 (97.2%) received drug-eluting stents. All eligible patients received bolus and cangrelor infusion between 2 and 4â h in 95% of the cases. A total of 730 patients (73.4%) received ticagrelor, 127 (12.8%) prasugrel, and 138 (13.9%) clopidogrel as transition therapy. Bleeding, according to Bleeding Academic Research Consortium (BARC) criteria, within 30 days post-PCI occurred in 5.2% of patients (95% confidence interval: 3.9-6.8%); 0.5% experienced a moderate (BARC 3), and all others mild (BARC 1-2) bleeding events. Major adverse cardiac events occurred in 14 (1.4%) patients, principally all-cause mortality (n = 6 patients) and myocardial infarction (n = 7 patients). Conclusion: The use of cangrelor in ACS patients undergoing PCI and the transition strategy to P2Y12 inhibitors are confirmed as safe and effective in daily practice.
RESUMEN
Antiplatelet therapy is the mainstay of pharmacologic treatment to prevent thrombotic or ischemic events in patients with coronary artery disease treated with percutaneous coronary intervention and those treated medically for an acute coronary syndrome. The use of antiplatelet therapy comes at the expense of an increased risk of bleeding complications. Defining the optimal intensity of platelet inhibition according to the clinical presentation of atherosclerotic cardiovascular disease and individual patient factors is a clinical challenge. Modulation of antiplatelet therapy is a medical action that is frequently performed to balance the risk of thrombotic or ischemic events and the risk of bleeding. This aim may be achieved by reducing (ie, de-escalation) or increasing (ie, escalation) the intensity of platelet inhibition by changing the type, dose, or number of antiplatelet drugs. Because de-escalation or escalation can be achieved in different ways, with a number of emerging approaches, confusion arises with terminologies that are often used interchangeably. To address this issue, this Academic Research Consortium collaboration provides an overview and definitions of different strategies of antiplatelet therapy modulation for patients with coronary artery disease, including but not limited to those undergoing percutaneous coronary intervention, and consensus statements on standardized definitions.

In the last decades, advances in percutaneous coronary intervention (PCI) strategies have significantly reduced the risk of procedural complications and in-hospital mortality of patients with acute coronary syndromes (ACS), thus increasing the population of stable post-ACS patients. This novel epidemiological scenario emphasizes the importance of implementing secondary preventive and follow-up strategies. The follow-up of patients after ACS or elective PCI should be based on common pathways and on the close collaboration between hospital cardiologists and primary care physicians. However, the follow-up strategies of these patients are still poorly standardized. This SICI-GISE/SICOA consensus document was conceived as a proposal for the long-term management of post-ACS or post-PCI patients based on their individual residual risk of cardiovascular adverse events. We defined five patient risk classes and five follow-up strategies including medical visits and examinations according to a specific time schedule. We also provided a short guidance for the selection of the appropriate imaging technique for the assessment of left ventricular ejection fraction and of non-invasive anatomical or functional tests for the detection of obstructive coronary artery disease. Physical and pharmacological stress echocardiography was identified as the first-line imaging technique in most of cases, while cardiovascular magnetic resonance should be preferred when an accurate evaluation of left ventricular ejection fraction is needed. The standardization of the follow-up pathways of patients with a history of ACS or elective PCI, shared between hospital doctors and primary care physicians, could result in a more cost-effective use of resources and potentially improve patient's long-term outcome.

Despite the increasing proportion of female medical and nursing students, there is still a significant under-representation of women working as healthcare providers in interventional cardiology, with very few of them reaching senior leadership, academic positions, or acting principal investigators, as well as actively involved in company advisory boards. In this position paper, we will describe the current status of women working in interventional cardiology across Europe. We will also provide an overview of the most relevant determinants of the under-representation of women at each stage of the interventional cardiology career path and offer practical suggestions for overcoming these challenges.

Single antiplatelet therapy represents the cornerstone of thrombosis prevention in atherosclerotic cardiovascular disease. Dual antiplatelet therapy (DAPT), consisting of aspirin plus a P2Y 12 inhibitor, is the standard of care for patients with acute coronary syndrome or undergoing both coronary and peripheral percutaneous interventions. Recent data suggest the efficacy of DAPT also after minor stroke. In this setting, a large body of evidence has documented that genetic and acquired patients' characteristics may affect the magnitude of platelet inhibition induced by antiplatelet agents. The implementation of tools allowing the identification and prediction of platelet inhibition has recently been shown to improve outcomes, leading to an optimal balance between antithrombotic efficacy and bleeding risk. We are therefore clearly moving towards tailored antiplatelet therapy. The aim of this paper is to summarize the available evidence on the evaluation of platelet inhibition in patients with coronary, peripheral, or cerebrovascular atherosclerosis. We will here focus on antiplatelet therapy based on both aspirin and P2Y 12 inhibitors. In addition, we provide practical insights into the clinical settings in which it appears reasonable to implement antiplatelet therapy monitoring.

Early menopause is associated with an increased risk of cardiovascular diseases, including aortic stenosis (AS). We sought to investigate the prevalence and impact of early menopause on clinical outcomes in patients who underwent transcatheter aortic valve implantation (TAVI) for severe symptomatic AS. Women's International TAVI is a multinational, prospective, observational registry of women who underwent TAVI for severe symptomatic AS (n = 1,019). Patients were divided into 2 groups based on age of menopause: early menopause (age ≤45 years) and regular menopause (age >45 years). The primary outcome of interest was Valve Academic Research Consortium 2 efficacy end point, a composite of mortality, stroke, myocardial infarction, hospitalization for valve-related symptoms, or heart failure or valve-related dysfunction at 1-year follow-up. Of 732 patients with available data on menopause age, 173 (23.6%) were classified as having early menopause. These patients presented for TAVI at a younger age (81.6 ± 6.9 vs 82.7 ± 5.9, p = 0.05) and had a significantly lower Society of Thoracic Surgeons score (6.6 ± 4.8 vs 8.2 ± 7.1, p = 0.03) than those with regular menopause. However, the total valve calcium volume was smaller among patients with early versus regular menopause (731.8 ± 850.9 mm3 vs 807.6 ± 633.8 mm3, p = 0.002). Other co-morbidities were similar between the 2 groups. At 1-year follow-up, there were no significant differences in clinical outcomes between patients with early versus regular menopause (hazard ratio 1.00, 95% confidence interval 0.61 to 1.63, p = 1.00). In conclusion, despite presenting for TAVI at a younger age, patients with early menopause had a similar risk of adverse events as patients with regular menopause at 1 year after TAVI.

BACKGROUND: Transcatheter aortic valve implantation (TAVI) has become an accepted treatment for patients with severe aortic stenosis (AS). Predicting which patients are at risk for adverse clinical outcomes after TAVI remains difficult, especially in women. AIM: To identify predictors of adverse events in the WIN-TAVI cohort. METHODS: The WIN-TAVI study is an observational registry of 1019 women undergoing TAVI for severe symptomatic AS. Follow-up was 1 year. The primary outcome was defined according to VARC-2: a composite of mortality, stroke, myocardial infarction or hospitalization for valve-related symptoms or heart failure. The secondary outcome was a composite of cardiovascular mortality or hospitalization for valve-related symptoms or heart failure. RESULTS: We included 1019 women with severe AS (mean age of 82.5 ± 6.3 years). At 1 year, 16.4% of the patients experienced the primary endpoint and 12.6% the secondary endpoint. The use of oral anticoagulants (OAC) was the strongest independent predictor of the primary outcome (adjusted hazard ratio [aHR] 1.51, 95% confidence interval [CI] 1.079-2.106, p = 0.016). Independent predictors of the secondary endpoint were age (aHR 1.04 per year, 95% CI 1.01-1.074, p = 0.016) and use of OAC (aHR: 1.79, 95% CI 1.24-2.60, p = 0.002). OAC use was not associated with higher bleeding risk. CONCLUSION: Pre-procedural use of OAC was the strongest predictor of adverse outcomes during 1-year follow-up, likely reflecting a combination of high-risk factors and comorbidities, but was not related to increased bleeding risk.

Background: In the ENVISAGE-TAVI AF (Edoxaban vs Standard of Care and Their Effects on Clinical Outcomes in Patients Having Undergone Transcatheter Aortic Valve Implantation-Atrial Fibrillation) trial, edoxaban was noninferior to vitamin K antagonists (VKA) for a composite outcome of ischemic and bleeding complications but increased major bleeding in patients with atrial fibrillation after successful transcatheter aortic valve replacement. Women are at higher risk of bleeding and stroke than men after transcatheter aortic valve replacement. It is unclear whether the effect of edoxaban on these complications varies in relation to sex. Objectives: This study was to assess the effect of edoxaban vs VKA according to sex in the ENVISAGE-TAVI AF trial. Methods: The primary outcomes were net adverse cardiovascular events (NACE) and major bleeding, assessed considering the effective time on study medication (safety analysis). Results: Out of 1,377 patients, 658 (47.8%) were women. Risks for ischemic and major bleeding outcomes were similar between women and men. Edoxaban compared to VKA was associated with a similar risk of NACE in women (HR: 1.16; 95% CI: 0.81-1.65) and men (HR: 1.08; 95% CI: 0.76-1.53; P for interaction = 0.820) and a higher risk of major bleeding in both sexes (P for interaction = 0.170). The risk increase of major bleeding was attenuated in women (HR: 1.11; 95% CI: 0.69-1.79) as compared to men (HR: 1.75; 95% CI: 1.07-2.85). There were no treatment-related differences for ischemic complications in both sexes. Conclusions: Edoxaban compared to VKA was associated with a similar risk of NACE and higher risk of major bleeding in both sexes. The increase in bleeding complications with edoxaban was attenuated in women.
RESUMEN
BACKGROUND: It is still unknown which antiplatelet monotherapy should be continued after a period of dual antiplatelet therapy (DAPT) in patients undergoing percutaneous coronary intervention (PCI). OBJECTIVES: The aim of this study was to compare aspirin vs P2Y12 inhibitor (P2Y12-I) monotherapy after dual antiplatelet therapy (DAPT) discontinuation in patients undergoing percutaneous coronary intervention (PCI). METHODS: Randomized studies enrolling patients undergoing PCI with second-generation drug-eluting stents and comparing aspirin or P2Y12-I monotherapy after DAPT discontinuation vs prolonged DAPT or aspirin vs P2Y12-I monotherapy after DAPT were included. Primary efficacy and safety endpoints were myocardial infarction (MI) and major bleeding (MB), respectively. Point estimates for dichotomous outcomes were pooled using frequentist and Bayesian frameworks. Sensitivity analyses and treatment hierarchy were performed. RESULTS: Nineteen studies encompassing 73,126 patients were included. The transitivity assumption was met. Under the frequentist framework, patients receiving aspirin had a significantly higher risk for MI compared with P2Y12-I monotherapy (risk ratio: 1.32; 95% CI: 1.08-1.62). Compared with DAPT, both monotherapies reduced MB, but only P2Y12-I showed equivalent efficacy in preventing MI. No significant differences in MB, death, and other thrombotic outcomes were observed. However, point estimates for the risk for stent thrombosis and stroke favored P2Y12-I monotherapy. Consistent results were found in a fixed-effects model and the Bayesian framework, with all models having adequate convergence. P2Y12-I vs aspirin monotherapy had the highest probability of being ranked first for reduction of all assessed outcomes. CONCLUSIONS: P2Y12-I monotherapy following DAPT discontinuation after PCI is associated with a significantly lower risk for MI and similar risk for MB, suggesting a potentially relevant net clinical benefit vs aspirin monotherapy. These findings strengthen the rationale for further studies directly comparing the 2 monotherapies after DAPT in PCI patients.

Dual antiplatelet therapy (DAPT) is the recommended treatment after percutaneous coronary intervention (PCI). The introduction into clinical practice of new drug-eluting stents (DESs) with significantly improved safety profiles has made it possible to shorten the DAPT. Randomized studies have established the superiority of DES over bare metal stents in high-bleeding risk (HBR) patients treated with antiplatelet monotherapy after 1 month of DAPT from PCI. This regimen has been adopted in randomized trials comparing different DES in patients with HBR. Furthermore, antiplatelet monotherapy after 1 month of DAPT from PCI has been shown to reduce bleeding risk without increasing ischaemic events compared with a conventional DAPT regimen (3-12 months) in a recent randomized study that included HBR patients treated with DES. Parallel to the trend of shortening DAPT, there is growing debate about which antiplatelet monotherapy is optimal after discontinuation of DAPT, with some recent studies exploring the paradigm shift from aspirin monotherapy to P2Y12 inhibitor monotherapy. Finally, future studies are underway to evaluate the clinical effect of monotherapy with ticagrelor or prasugrel directly after implantation of DES thus eliminating DAPT.
RESUMEN
Gender-based differences in outcomes after successful transcatheter aortic valve implantation (TAVI) in patients without an indication for oral anticoagulation have not been well studied. We aim to evaluate gender-based differences in clinical outcomes after TAVI. In the present analysis of the GALILEO (Global study comparing a rivaroxaban-based antithrombotic strategy to an antiplatelet-based strategy after transcatheter aortic valve replacement to optimize clinical outcomes) trial, patients with symptomatic severe aortic stenosis and who underwent successful TAVI were stratified by gender. The primary outcome was major adverse cardiac and cerebrovascular events (MACCEs), a composite of all-cause mortality or thromboembolic events (including any stroke, myocardial infarction, symptomatic valve thrombosis, systemic embolism, deep-vein thrombosis, or pulmonary embolism). Major bleeding was defined as a composite of major, life-threatening, or disabling Valve Academic Research Consortium-2 bleeding. Of 1,644 patients, 813 were female, and 831 were male. At baseline, female patients were older and at higher surgical risk (Society of Thoracic Surgeons risk score: 4.7 ± 3.6 versus 3.6 ± 3.0, p <0.0001) than male patients. After adjustment for differences in baseline clinical and procedural parameters, female patients had lower rates of MACCE (hazard ratio [HR] 0.69, 95% confidence interval [CI] 0.49 to 0.96), all-cause mortality (HR 0.54, 95% CI 0.34 to 0.87), and noncardiovascular mortality (HR 0.33, 95% CI 0.15 to 0.75) at a median of 17 months of follow-up. By landmark analyses, these differences appeared to emerge with a longer follow-up time. No significant differences in major, life-threatening, or disabling bleeding, cardiovascular mortality, and stroke were noted. In conclusion, compared with male patients, female patients with severe symptomatic aortic stenosis had a lower risk of MACCE and mortality but a similar risk of bleeding events after TAVI.

BACKGROUND: The itAlian pRospective Study on CANGrELOr (ARCANGELO) was aimed to assess the safety of using cangrelor during percutaneous coronary intervention (PCI) in patients with acute coronary syndromes (ACS) in the daily practice. HYPOTHESIS: The safety of cangrelor after the transition to oral P2Y12 inhibitors was evaluated as the incidence of bleeding outcomes in the 30 days following PCI according to postauthorization safety study guidelines. METHODS: Adults with ACS who were treated with cangrelor in one of the 28 centers involved in the study. Patients who consented to participate were followed in the 30 days following their PCI. Bleedings (Bleeding Academic Research Consortium [BARC] classification), major adverse cardiac events (MACEs), and adverse events were recorded. The interim results at two-thirds of the enrollment period are presented. RESULTS: A total of 17 bleedings were observed in the 320 patients who completed the study at this stage. All bleedings were classified as BARC Type 1-2, except for one case of Type 3a (vessel puncture site hematoma). Four patients experienced MACEs (2 acute myocardial infarctions, 1 sudden cardiac death, 1 noncardiovascular death due to respiratory distress, and multiorgan failure). None of the bleedings was rated as related to cangrelor. CONCLUSIONS: The interim results of the ARCANGELO study provide a preliminary confirmation that the use of cangrelor on patients with ACS undergoing PCI is not associated with severe bleedings.
