Abstract
BACKGROUND Large-vessel ischemic stroke represents about 25-40% of all ischemic strokes. Few clinical trials compared ticagrelor versus clopidogrel in ischemic stroke patients; all these studies included only patients with a transient ischemic attack or minor stroke; moreover, none of these studies included patients from North Africa. OBJECTIVES We aimed to compare ticagrelor versus clopidogrel in the first-ever large-vessel occlusion (LVO) acute ischemic stroke in Egypt. METHODS Our trial involved 580 first-ever LVO ischemic stroke patients who were randomly assigned to administer loading and maintenance doses of ticagrelor or clopidogrel. Screening, randomization, and start of treatment occurred during the first 24 hours of the stroke. RESULTS 580 patients were included in the intention-to-treat analysis. Thirty patients in the ticagrelor group and 49 patients in the clopidogrel group experienced a new ischemic or hemorrhagic stroke at 90 days (hazard ratio [HR] 0.61; 95% confidence interval [CI] 0.38-0.98; p-value = 0.04), 36 patients in the ticagrelor group, and 57 in the clopidogrel group experienced composite of a new stroke, myocardial infarction, or death due to vascular insults (HR 0.56; 95% CI 0.37-0.87; p = 0.009). Patients who received ticagrelor had better clinical outcomes regarding National Institutes of Health Stroke Scale (NIHSS) reduction and a favorable modified Rankin scale (mRS) score. There were no differences between ticagrelor and clopidogrel regarding hemorrhagic and non-hemorrhagic complications. CONCLUSION Patients with acute large-vessel ischemic stroke who received ticagrelor within the first 24 hours after ischemic stroke had better clinical outcomes based on recurrent stroke rates, NIHSS reduction, and favorable mRS rates compared with those who received clopidogrel. There were no differences between ticagrelor and clopidogrel regarding hemorrhagic and non-hemorrhagic complications. TRIAL REGISTRATION Clinical trials.gov (NCT06120725).

Abstract
BACKGROUND Ticagrelor reduced major adverse cardiovascular events (MACE) and increased bleeding in patients with type 2 diabetes mellitus (T2DM) and coronary artery disease. Limb events including revascularization, acute limb ischemia (ALI), and amputation are major morbidities in patients with T2DM and atherosclerosis. OBJECTIVES This study sought to determine the effect of ticagrelor on limb events. METHODS Patients were randomized to ticagrelor or placebo on top of aspirin and followed for a median of 3 years. MACE (cardiovascular death, myocardial infarction, or stroke), limb events (ALI, amputation, revascularization), and bleeding were adjudicated by an independent and blinded clinical events committee. The presence of peripheral artery disease (PAD) was reported at baseline. RESULTS Of 19,220 patients randomized, 1,687 (8.8%) had PAD at baseline. In patients receiving placebo, PAD was associated with higher MACE (10.7% vs 7.3%; HR: 1.48; P < 0.001) and limb (9.5% vs 0.8%; HR: 10.67; P < 0.001) risk. Ticagrelor reduced limb events (1.6% vs 1.3%; HR: 0.77; 95% CI: 0.61-0.96; P = 0.022) with significant reductions for revascularization (HR: 0.79; 95% CI: 0.62-0.99; P = 0.044) and ALI (HR: 0.24; 95% CI: 0.08-0.70; P = 0.009). The benefit was consistent with or without PAD (HR: 0.80; 95% CI: 0.58-1.11; and HR: 0.76; 95% CI: 0.55-1.05, respectively; Pinteraction = 0.81). There was no effect modification of ticagrelor vs placebo based on PAD for MACE (Pinteraction = 0.40) or TIMI major bleeding (Pinteraction = 0.3239). CONCLUSIONS Patients with T2DM and atherosclerosis are at high risk of limb events. Ticagrelor decreased this risk, but increased bleeding. Future trials evaluating the combination of ticagrelor and aspirin would further elucidate the benefit/risk of such therapy in patients with PAD, including those without coronary artery disease.

Abstract
BACKGROUND An ABCD-GENE (age, body mass index, chronic kidney disease, diabetes, and CYP2C19 genetic variants) score ≥10 predicts reduced clopidogrel effectiveness, but its association with response to alternative therapy remains unclear. OBJECTIVES The aim of this study was to evaluate the association between ABCD-GENE score and the effectiveness of clopidogrel vs alternative P2Y12 inhibitor (prasugrel or ticagrelor) therapy after percutaneous coronary intervention (PCI). METHODS A total of 4,335 patients who underwent PCI, CYP2C19 genotyping, and P2Y12 inhibitor treatment were included. The primary outcome was major atherothrombotic events (MAE) within 1 year after PCI. Cox regression was performed to assess event risk in clopidogrel-treated (reference) vs alternatively treated patients, with stabilized inverse probability weights derived from exposure propensity scores after stratifying by ABCD-GENE score and further by CYP2C19 loss-of-function (LOF) genotype. RESULTS Among patients with scores <10 (n = 3,200), MAE was not different with alternative therapy vs clopidogrel (weighted HR: 0.89; 95% CI: 0.65-1.22; P = 0.475). The risk for MAE also did not significantly differ by treatment among patients with scores ≥10 (n = 1,135; weighted HR: 0.75; 95% CI: 0.51-1.11; P = 0.155). Among CYP2C19 LOF allele carriers, MAE risk appeared lower with alternative therapy in both the group with scores <10 (weighted HR: 0.50; 95% CI: 0.25-1.01; P = 0.052) and the group with scores ≥10 (weighted HR: 0.48; 95% CI: 0.29-0.80; P = 0.004), while there was no difference in the group with scores <10 and no LOF alleles (weighted HR: 1.03; 95% CI: 0.70-1.51; P = 0.885). CONCLUSIONS These data support the use of alternative therapy over clopidogrel in CYP2C19 LOF allele carriers after PCI, regardless of ABCD-GENE score, while clopidogrel is as effective as alternative therapy in non-LOF patients with scores <10.

Abstract
BACKGROUND Data on P2Y12 inhibitors responsiveness from the middle east is scarce. We sought to investigate patient responsiveness to P2Y12 inhibitors within a cohort of major races that characterize the UAE population. The secondary objective was to assess risk factors for hyper and hypo-responsiveness in this population. METHODS We conducted a cross-sectional study on adults who received either clopidogrel or ticagrelor treatments and had platelet responsiveness testing before undergoing neuro-endovascular interventions at our quaternary care hospital between March 2015 and April 2019. RESULTS During the study period, 249 subjects met the inclusion criteria. Overall, 17.3 % were hyper-responsive and 25.7 % were hypo-responsive to P2Y12 inhibitors. When comparing between the P2Y12 inhibitors, rates of hyper-responsiveness were significantly higher to ticagrelor when compared to clopidogrel (11 versus 6 %, p = 0.02 respectively). Contrarily, hypo-responsiveness rates were significantly higher in clopidogrel treated patients compared to their ticagrelor treated counterparts (23 versus 2 %, p < .001 respectively). Patients of Middle-Eastern origin showed a significantly higher rate of hypo-responsiveness to both clopidogrel and ticagrelor when compared to other races (41.1 % and 26.7 %, P < 0.001 respectively). Asians showed the highest rates of hyper-responsiveness for both agents. Multivariate logistic regression analysis showed that proton pump inhibitors and statin combination, (OR: 6.39, 95 %CI [1.60, 25.392]), and Middle East vs. Indian subcontinent patients (OR: 4.67, 95 %CI [1.79-12.14]) were independent predictors of hypo-responsiveness to both P2Y12 inhibitors. CONCLUSION This study demonstrated a high rate of hypo-responsiveness to P2Y12 inhibitors in a UAE cohort of patients undergoing neuro-endovascular procedures. In addition, therapeutic responsiveness to P2Y12 inhibitors varied markedly based on the racial background. Future larger studies are needed to evaluate genetic variations that may contribute to this rate of hypo-responsiveness in our population.

Abstract
Low-dose prasugrel demonstrated a similar effectiveness profile to clopidogrel in East Asian ACS patients, but its comparison with another new-generation potent P2Y12 inhibitor, ticagrelor, remains unclear. To compare the effectiveness and safety of low-dose prasugrel against those of standard-dose ticagrelor in East Asian patients with ACS. This retrospective cohort study used Taiwan's National Health and Welfare Database. This study included ACS patients who underwent percutaneous coronary intervention and, at discharge between January 1, 2018 and December 31, 2020, were prescribed with low-dose prasugrel plus aspirin or standard-dose ticagrelor plus aspirin. Stabilized inverse probability of treatment weighting was used to balance the covariates across these two groups. The primary effectiveness outcome was a composite of acute myocardial infarction, ischemic stroke, and cardiovascular death; the secondary effectiveness outcome was each of the individual components of the primary outcome, transient ischemic attack, and repeat revascularization. The primary safety outcome was a composite of intracranial hemorrhage and gastrointestinal bleeding, and the two secondary safety outcomes were intracranial hemorrhage and gastrointestinal bleeding. A total of 24,807 patients were included in this study. Among them, 1,493 were low-dose prasugrel users and 23,314 were standard-dose ticagrelor users. No significant differences were found in primary effectiveness [HR: 0.97 (0.74-1.28)] or primary safety outcomes [HR: 1.22 (0.73-2.01)] between the two study groups. For East Asian patients with ACS, low-dose prasugrel provides comparable effectiveness without increasing bleeding risk compared to standard-dose ticagrelor. Low-dose prasugrel may be an appropriate alternative for East Asian populations.

Abstract
BACKGROUND Impaired endogenous fibrinolysis is adverse cardiovascular risk factor in acute coronary syndrome (ACS) patients. Addition of very low dose rivaroxaban (VLDR) to dual antiplatelet therapy (DAPT) reduces cardiovascular events but increases bleeding. OBJECTIVE We aimed to assess whether addition of VLDR to DAPT can enhance endogenous fibrinolysis. METHODS In a prospective, open-label trial, we assessed endogenous fibrinolysis in whole blood, in 549 patients with ACS using the Global Thrombosis Test (GTT) and Thromboelastography (TEG). Patients (n = 180) who demonstrated impaired endogenous fibrinolysis (lysis time [LT] >2000s with the GTT) were randomised 1:1:1 to (i) clopidogrel 75 mg daily; (ii) clopidogrel 75 mg daily plus rivaroxaban 2.5 mg twice daily; or (iii) ticagrelor 90 mg twice daily, for 30 days, in addition to aspirin. Fibrinolytic status was assessed at 0, 2, 4 and 8 weeks. The primary outcome was the change in LT from admission to week 4. We also measured thrombotic occlusion time (OT) at high shear, and rivaroxaban level. RESULTS There was no difference between the groups with respect to LT or clot lysis with TEG, and no change in these parameters compared to baseline during study drug allocation. In the rivaroxaban plus clopidogrel group, OT was prolonged compared to the other groups, although rivaroxaban levels were low, suggesting non-compliance. CONCLUSION Addition of rivaroxaban 2.5 mg twice daily to DAPT does not affect endogenous fibrinolysis of thrombus formed at either high or low shear. Further studies are needed to determine whether higher doses of rivaroxaban can favourably modulate fibrinolysis. CONDENSED ABSTRACT Impaired endogenous fibrinolysis is a strong risk factor in ACS. We aimed to assess whether adding very low dose rivaroxaban (VLDR) to DAPT can enhance fibrinolysis. Fibrin and clot lysis were assessed in whole blood. ACS patients with impaired fibrinolysis were randomised 1:1:1 to clopidogrel 75 mg daily; clopidogrel 75 mg plus VLDR; or ticagrelor 90 mg twice daily, in addition to aspirin. At 30-days, there was no difference in lysis time between the groups, nor change from baseline. VLDR does not improve fibrinolysis at high or low shear. Further studies are needed to determine whether alternative antithrombotic regimens can enhance endogenous fibrinolysis.

Abstract
BACKGROUND Antiplatelet therapy is pivotal in endovascular treatment for intracranial aneurysms. However, there is a lack of studies comparing ticagrelor to clopidogrel in patients with aneurysms undergoing endovascular therapy. Additionally, the existing literature lacks adequate sample size, significant subgrouping, and follow-up, making our study important to cover these gaps. METHODS We searched 5 databases to collect all relevant studies. Categorical outcomes were pooled as relative risk (R.R.) with a 95% confidence interval (CI). In the single-arm meta-analysis, outcomes were pooled as proportions and their corresponding 95% CI. RESULTS This comprehensive analysis of 18 studies involving 2,427 patients. For thromboembolic events, the pooled (R.R.) did not show significant differences, whether considering overall events. A similar pattern was observed for thromboembolic events stratified by aneurysmal rupture status, with no significant differences in overall events. Hemorrhagic events did not also exhibit significant differences in previously mentioned stratifications. Furthermore, there were no substantial differences in death and mRS (0-2) on discharge between Ticagrelor and Clopidogrel. Single-arm meta-analyses for Ticagrelor demonstrated low rates of thromboembolic events, hemorrhage, death, and favorable mRS scores, with associated confidence intervals (CIs). Main line of endovascular treatment did not significantly affect either thromboembolic or hemorrhagic outcomes with Ticagrelor and Clopidogrel. CONCLUSIONS We found no significant differences in key outcomes like thromboembolic events, hemorrhagic events, mortality rates, and favorable mRS (0-2) upon discharge in the studied patients between Ticagrelor and Clopidogrel. Moreover, the single-arm meta-analysis for Ticagrelor revealed low rates of thromboembolic events, hemorrhage, mortality, and high rates of favorable mRS scores.

Abstract
The optimal antiplatelet strategy after coronary artery bypass graft (CABG) surgery in patients with chronic coronary syndromes (CCS) is unclear. Adding the P2Y12 inhibitor, ticagrelor, to low-dose aspirin for 1 year is associated with a reduction in graft failure, particularly saphenous vein grafts, at the expense of an increased risk of clinically important bleeding. As the risk of thrombotic graft failure and ischaemic events is highest early after CABG surgery, a better risk-to-benefit profile may be attained with short-term dual antiplatelet therapy followed by single antiplatelet therapy. The One Month Dual Antiplatelet Therapy With Ticagrelor in Coronary Artery Bypass Graft Patients (ODIN) trial is a prospective, randomised, double-blind, placebo-controlled, international, multicentre study of 700 subjects that will evaluate the effect of short-term dual antiplatelet therapy with ticagrelor plus low-dose aspirin after CABG in patients with CCS. Patients will be randomised 1:1 to ticagrelor 90 mg twice daily or matching placebo, in addition to aspirin 75-150 mg once daily for 1 month; after the first month, antiplatelet therapy will be continued with aspirin alone. The primary endpoint is a hierarchical composite of all-cause death, stroke, myocardial infarction, revascularisation and graft failure at 1 year. The key secondary endpoint is a hierarchical composite of all-cause death, stroke, myocardial infarction, Bleeding Academic Research Consortium (BARC) type 3 bleeding, revascularisation and graft failure at 1 year (net clinical benefit). ODIN will report whether the addition of ticagrelor to low-dose aspirin for 1 month after CABG reduces ischaemic events and provides a net clinical benefit in patients with CCS.

Abstract
In brief Preterm birth is the leading cause of perinatal morbidity and mortality, and new therapies that delay preterm birth and improve neonatal outcomes are urgently needed. This study investigates whether ticagrelor inhibits uterine contractility and inflammation in preclinical in vitro, ex vivo (human) and in vivo (mouse) studies, to explore the potential of repurposing ticagrelor for the prevention of preterm birth. Abstract Preterm birth remains a significant global health challenge, affecting approximately 10% of pregnancies and resulting in one million deaths globally every year. Tocolytic agents, used to manage preterm labour, have considerable limitations including lack of efficacy, and adverse side effects, emphasising the urgent need for innovative solutions. Here, we explore repurposing an antiplatelet cardioprotective drug, ticagrelor, as a potential treatment to prevent preterm birth. Ticagrelor has demonstrated pleiotropic actions beyond platelet inhibition, including relaxant effects on smooth muscle cells and anti-inflammatory effects in models of diabetes and sepsis. As preterm birth is underscored by inflammatory processes triggering uterine contractions, these actions position ticagrelor as an attractive candidate for prevention or delay of preterm birth. Utilising primary human myometrial tissue, human myometrial cells, and a mouse model of preterm birth, we investigated ticagrelor's potential as a safe and effective therapy for preterm birth. We showed that ticagrelor did not reduce the frequency or strength of spontaneous muscle contractions of ex vivo myometrial tissue nor did it reduce in vitro inflammation-induced contractility in myometrial cells. Additionally, ticagrelor did not exhibit the anticipated anti-inflammatory effects in myometrial cell culture experiments. In our mouse model of preterm birth, ticagrelor neither improved the preterm birth rate or fetal survival outcomes. Gene expression of pro-inflammatory cytokines and contraction-associated proteins in postpartum mouse uteri were unaltered by ticagrelor. In conclusion, ticagrelor is not a strong candidate to continue investigations in clinical trial for the treatment of preterm labour and prevention of preterm birth.

Abstract
BACKGROUND To date, there are no data on switching to dual pathway inhibition (DPI) patients who have completed a guideline-recommended dual antiplatelet therapy (DAPT) regimen. OBJECTIVES To assess the feasibility of switching from DAPT to DPI and to compare the pharmacodynamic (PD) profiles of these treatments. METHODS This was a prospective, randomized, PD study conducted in 90 patients with chronic coronary syndrome (CCS) on DAPT with aspirin (81 mg/qd) plus a P2Y12 inhibitor (clopidogrel [75 mg/qd; n = 30], ticagrelor [90 mg/bid; n = 30], or prasugrel [10 mg/qd; n = 30]). Patients in each cohort were randomized to maintain DAPT or switch to DPI (aspirin 81 mg/qd plus rivaroxaban 2.5 mg/bid). PD assessments included: VerifyNow P2Y12 reaction units; light transmittance aggregometry following stimuli with adenosine diphosphate (ADP), tissue factor (TF), and a combination of collagen, ADP, and TF (maximum platelet aggregation %); thrombin generation (TG). Assays were performed at baseline and 30 days postrandomization. RESULTS Switching from DAPT to DPI occurred without major side effects. DAPT was associated with enhanced P2Y12 inhibition, while DPI with reduced TG. Platelet-mediated global thrombogenicity (primary endpoint) showed no differences between DAPT and DPI in the ticagrelor (14.5% [0.0-63.0] vs. 20.0% [0.0-70.0]; p = 0.477) and prasugrel (20.0% [0.0-66.0] vs. 4.0% [0.0-70.0]; p = 0.482), but not clopidogrel (27.0% [0.0-68.0] vs. 53.0% [0.0-81.0]; p = 0.011), cohorts. CONCLUSION In patients with CCS, switching from different DAPT regimens to DPI was feasible, showing enhanced P2Y12 inhibition with DAPT and reduced TG with DPI, with no differences in platelet-mediated global thrombogenicity between DPI and ticagrelor- and prasugrel-, but not clopidogrel-, based DAPT.

Abstract
This study aim to investigate if remote intensive coaching for the first 6 months post-AMI will improve adherence to the twice-a-day antiplatelet medication, ticagrelor. Between July 8, 2015, to March 29, 2019, AMI patients were randomly assigned to remote intensive management (RIM) or standard care (SC). RIM participants underwent 6 months of weekly then two-weekly consultations to review medication side effects and medication adherence coaching by a centralized nurse practitioner team, whereas SC participants received usual cardiologist face-to-face consultations. Adherence to ticagrelor were determined using pill counting and serial platelet reactivity measurements for 12 months. A total of 149 (49.5%) of participants were randomized to RIM and 152 (50.5%) to SC. Adherence to ticagrelor was similar between RIM and SC group at 1 month (94.4 ± 0.7% vs. 93.6±14.7%, p = 0.537), 6 months (91.0±14.6% vs. 90.6±14.8%, p = 0.832) and 12 months (87.4±17.0% vs. 89.8±12.5%, p = 0.688). There was also no significant difference in platelet reactivity between the RIM and SC groups at 1 month (251AU*min [212-328] vs. 267AU*min [208-351], p = 0.399), 6 months (239AU*min [165-308] vs. 235AU*min [171-346], p = 0.610) and 12 months (249AU*min [177-432] vs. 259AU*min [182-360], p = 0.678). Sensitivity analysis did not demonstrate any association of ticagrelor adherence with bleeding events and major adverse cardiovascular events. RIM, comprising 6 months of intensive coaching by nurse practitioners, did not improve adherence to the twice-a-day medication ticagrelor compared with SC among patients with AMI. A gradual decline in ticagrelor adherence over 12 months was observed despite 6 months of intensive coaching.

Abstract
BACKGROUND AND OBJECTIVE The relationship between hyperuricemia and mortality in patients with acute coronary syndrome (ACS) is considerably controversial. Additionally, the strategy of dual antiplatelet therapy (DAPT) has not been evaluated in patients with ACS with hyperuricemia. This study aims to evaluate the impact of hyperuricemia on the prognosis of ACS and explore the efficacy of ticagrelor compared with clopidogrel in patients with hyperuricemia. METHODS The study enrolled 4319 patients divided into hyperuricemia (HUA, n = 1060) and normouricemia (NUA, n = 3259) groups. The inverse probability of treatment weighting (IPTW)-adjusted Cox regression analysis was used to evaluate the impact of ticagrelor versus clopidogrel on all-cause and cardiovascular mortality. RESULTS Hyperuricemia significantly increased the risk of all-cause death compared with patients with NUA at 7 days [adjusted hazard ratio (HR): 4.292, 95% confidence interval (CI) 1.727-10.67]; P = 0.002), 14 days (adjusted HR: 2.871, 95% CI 1.326-6.219; P = 0.0074), 30 days (adjusted HR: 2.168, 95% CI 1.056-4.453; P = 0.035), 3 months (adjusted HR: 2.018, 95% CI 1.152-3.533; P = 0.0144) and 1 year (adjusted HR: 1.702, 95% CI 1.137-2.548; P = 0.009). No significant difference was found between ticagrelor and clopidogrel in 1-year all-cause mortality [7.0% versus 5.5%, adjusted HR: 1.114 (95% CI 0.609-2.037), P = 0.725] among patients with concomitant hyperuricemia. CONCLUSION Hyperuricemia was independently related to an increased risk of all-cause and cardiovascular death in patients with ACS undergoing PCI. At 1-year follow-up, there were no significant differences between ticagrelor and clopidogrel concerning all-cause and cardiovascular death in patients with hyperuricemia.

Abstract
INTRODUCTION Patients of acute coronary syndrome (ACS) at a high-bleeding risk (HBR) often require dual antiplatelet therapy (DAPT) to reduce the risk of recurrent cardiovascular events. Clopidogrel and ticagrelor are the most commonly used antiplatelet agents in DAPT regimens. However, the safety profiles of these drugs in ACS patients at HBR remain a subject of ongoing debate. AIM To investigate any difference between the safety of clopidogrel and ticagrelor used as a part of DAPT regimen in ACS patients at HBR. METHODS A systematic search on PubMed, Cochrane Library, and Google Scholar was conducted to identify experimental and observational studies published up to the knowledge cutoff date in September 2023. Studies comparing the safety of clopidogrel and ticagrelor in ACS patients at HBR were included for analysis. The primary outcomes assessed were major bleeding events, stroke, and myocardial infarction (MI), while secondary outcomes included all-cause mortality, major adverse cardiac and cerebrovascular events (MACCE), and net adverse clinical and cerebral events (NACCE). RESULTS We included a total of 8 observational studies in our meta-analysis. The pooled analysis revealed a statistically significant increase in the risk of MI (pooled RR = 1.43; 95% CI 1.12-1.83; P = 0.005) in the patients using clopidogrel. There were no statistically significant differences in major bleeding events (pooled RR = 0.94; 95% CI 0.82-1.09; P = 0.44), stroke (pooled RR = 1.36; 95% CI 0.86-2.14; P = 0.18), all-cause mortality (pooled RR = 1.17; 95% CI 0.97-1.41; P = 0.10), MACCE (pooled RR = 1.07; 95% CI 0.76-1.50; P = 0.69) and NACCE (pooled RR = 0.95; 95% CI 0.66-1.37; P = 0.78) between the two groups. Subgroup analyses based on region were performed. CONCLUSION Both drugs are generally safe for treating ACS patients with HBR at baseline, although a higher risk of MI was observed with the use of clopidogrel. Nevertheless, drug choice should factor in regional variations, patient-specific characteristics, cost, accessibility, and potential drug interactions.

Abstract
BACKGROUND AND OBJECTIVES The Ticagrelor or Clopidogrel with Aspirin in High-Risk Patients with Acute Nondisabling Cerebrovascular Events II (CHANCE-2) trial showed that among Chinese patients with minor ischemic stroke or transient ischemic attack (TIA) who were carriers of CYP2C19 loss-of-function alleles, dual-antiplatelet therapy with ticagrelor-aspirin reduced the 90-day risk of stroke without increased severe or moderate bleeding compared with clopidogrel-aspirin. However, whether dual-antiplatelet therapy with ticagrelor was superior to clopidogrel beyond the 90 days of follow-up remained unclear. In this study, we reported 1-year follow-up outcomes of the CHANCE-2 trial. METHODS The CHANCE-2 trial is a randomized, double-blind, placebo-controlled trial at 202 centers in China. Patients with a minor stroke or TIA who carried CYP2C19 loss-of-function alleles were randomized within 24 hours after symptom onset, in a 1:1 ratio, to receive ticagrelor and placebo clopidogrel or to receive clopidogrel and placebo ticagrelor for 90 days; both groups received aspirin for the first 21 days. After day 90, treatment was as per the choice of the clinician and the patient. RESULTS Among 6,412 patients, the proportion of patients on ticagrelor plus aspirin, clopidogrel plus aspirin, ticagrelor alone, clopidogrel alone, aspirin alone, other antiplatelet, and no antiplatelet beyond month 3 to 1 year was 0.09%, 1.56%, 0.13%, 2.66%, 73.65%, 0.78%, and 21.13% in the ticagrelor-aspirin group and 0.03%, 1.63%, 0.19%, 2.60%, 72.83%, 0.66%, and 22.06% in the clopidogrel-aspirin group, respectively. The primary outcome of new stroke occurred in 252 patients (7.91%) in the ticagrelor-aspirin group and 310 patients (9.73%) in the clopidogrel-aspirin group by 1 year of follow-up (hazard ratio 0.80; 95% CI 0.68-0.95; p = 0.007); new stroke beyond 3 months to 1 year occurred in 61 patients (2.07%) and 67 patients (2.32%) (p = 0.48), respectively. Primary safety outcome of severe or moderate bleeding occurred in 17 patients (0.53%) in the ticagrelor-aspirin group and 20 patients (0.63%) in the clopidogrel-aspirin group (p = 0.61). DISCUSSION For CYP2C19 loss-of-function allele carriers, early dual-antiplatelet therapy with ticagrelor is superior to clopidogrel at 1 year in reducing recurrent stroke. TRIAL REGISTRATION INFORMATION URL: clinicaltrials.gov. Unique identifier: NCT04078737. CLASSIFICATION OF EVIDENCE This study provides Class II evidence that for patients with minor stroke or TIA with TIACYP2C19 loss-of-function, ticagrelor plus aspirin for 21 days is superior to clopidogrel plus aspirin in reducing the 1-year risk of recurrent stroke.

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 Elevated homocysteine levels are associated with increased blood coagulation and platelet activity and may modulate the response to antiplatelet therapies. We aimed to investigate the effects of homocysteine levels on the efficacy and safety of ticagrelor-acetylsalicylic acid (ASA) versus clopidogrel-ASA among patients with minor stroke or transient ischemic attack who carried CYP2C19 loss-of-function alleles. METHODS We conducted a post hoc analysis of the CHANCE-2 (The Clopidogrel in High-risk Patients with Acute Nondisabling Cerebrovascular Events-II) trial. Participants were randomly assigned to treatment with ticagrelor-ASA or clopidogrel-ASA. We categorized participants into groups with elevated and non-elevated homocysteine levels, based on the median level. The primary efficacy outcome was recurrent stroke within 90-day follow-up. The primary safety outcome was severe or moderate bleeding within 90 days. RESULTS A total of 2740 participants were randomly assigned to receive ticagrelor-ASA and 2700 to receive clopidogrel-ASA. Use of ticagrelor-ASA was associated with a reduced risk of recurrent stroke among participants with elevated homocysteine levels (74 [5.3%] v. 119 [8.5%]; hazard ratio [HR] 0.60, 95% confidence interval [CI] 0.45-0.81), but not among those with non-elevated levels (86 [6.4%] v. 87 [6.7%]; HR 0.97, 95% CI 0.71-1.32; p = 0.04 for interaction). When analyzed as a continuous variable, the benefits of ticagrelor-ASA with regard to recurrent stroke increased as homocysteine levels increased (p = 0.04 for interaction). No significant interaction between homocysteine levels and treatment with regard to severe or moderate bleeding was observed (p = 0.7 for interaction). We found a significant interaction between homocysteine levels and therapy with regard to recurrent stroke in females (p = 0.04 for interaction) but not males. INTERPRETATION In comparison with clopidogrel-ASA, ticagrelor-ASA conferred more benefit to patients with elevated homocysteine levels, particularly to female patients, in this secondary analysis of a randomized controlled trial involving patients with minor ischemic stroke or TIA. TRIAL REGISTRATION ClinicalTrials.gov, no. NCT04078737.

Abstract
BACKGROUND Dual antiplatelet therapy (DAPT) is commonly employed for neuroendovascular stenting due to the significant risk of thromboembolism. Clopidogrel and aspirin are most often selected as initial DAPTs; however, there is limited literature available to support guidance of DAPT in this setting. The objective of this study was to evaluate safety and efficacy in patients whose final regimen included either DAPT with aspirin and clopidogrel (DAPT-C) or DAPT with aspirin and ticagrelor (DAPT-T). METHODS This was a multicenter, retrospective cohort of patients who underwent neuroendovascular stenting and received DAPT between July 1, 2017, and October 31, 2020. Study participants were allocated into groups based on discharge DAPT regimen. The primary outcome was incidence of stent thrombosis at 3-6 months on DAPT-C versus DAPT-T, as defined by the presence of thrombus on imaging or new onset stroke. Secondary outcomes included major and minor bleeding and death within 3-6 months after the procedure. RESULTS Five hundred and seventy patients were screened across 12 sites. Of those, 486 were included (DAPT-C n = 360, DAPT-T n = 126). There was no difference in the primary outcome of stent thrombosis between the DAPT-C and DAPT-T groups (8% vs. 8%, p = 0.97) and no difference in any of the secondary safety outcomes. CONCLUSIONS Using DAPT-C or DAPT-T regimens in a broad population of neuroendovascular stenting procedures appears to have similar safety and efficacy profiles. Further prospective evaluation is warranted to streamline the practice of DAPT selection and monitoring to determine the impact on clinical outcomes.

Abstract
AIMS The study aimed to estimate the cost-effectiveness of CYP2C19 genotype-guided antiplatelet therapy using cilostazol and ticagrelor as an alternative to clopidogrel, compared to conventional antiplatelet therapy with clopidogrel and aspirin. METHODS A 90-day decision tree and 30-year Markov model were employed to assess the costs and quality-adjusted life years (QALYs) of personalized antiplatelet therapy for patients with minor ischemic stroke and high-risk transient ischemic attack, compared to conventional antiplatelet therapy in the Chinese healthcare system. The primary outcome was the incremental cost-effectiveness ratio (ICER). The data sources included clinical trials, published literature, official documents and local prices. One-way sensitivity analysis and probabilistic sensitivity analysis were performed to confirm the robustness of the findings. RESULTS The base-case analysis indicated that the CYP2C19 genotype-guided antiplatelet strategy was cost-effective, and cilostazol group and ticagrelor group yielded an ICER of 3327.40 US dollars (USD)/QALY and 3426.92 USD/QALY, respectively, which were less than threshold. The one-way sensitivity analysis showed the results were robust, where the most sensitive parameter was the disability distribution in the modified Rankin scale 3-5. The probabilistic analysis showed that the CYP2C19 genotype-guided antiplatelet therapy with either cilostazol or ticagrelor was 100% cost-effective under the willingness-to-pay threshold. CONCLUSIONS CYP2C19 genotype-guided antiplatelet therapy using cilostazol and ticagrelor as an alternative to clopidogrel appeared to be more cost-effective than conventional antiplatelet therapy for acute minor ischemic stroke and high-risk transient ischemic attack patients over 30 years in China.

Abstract
BACKGROUND Identifying patients with the optimal risk:benefit for ticagrelor is challenging. The aim was to identify ticagrelor-responsive platelet transcripts as biomarkers of platelet function and cardiovascular risk. METHODS Healthy volunteers (n=58, discovery; n=49, validation) were exposed to 4 weeks of ticagrelor with platelet RNA data, platelet function, and self-reported bleeding measured pre-/post-ticagrelor. RNA sequencing was used to discover platelet genes affected by ticagrelor, and a subset of the most informative was summarized into a composite score and tested for validation. This score was further analyzed (1) in CD34+ megakaryocytes exposed to an P2Y12 inhibitor in vitro, (2) with baseline platelet function in healthy controls, (3) in peripheral artery disease patients (n=139) versus patient controls (n=30) without atherosclerosis, and (4) in patients with peripheral artery disease for correlation with atherosclerosis severity and risk of incident major adverse cardiovascular and limb events. RESULTS Ticagrelor exposure differentially expressed 3409 platelet transcripts. Of these, 111 were prioritized to calculate a Ticagrelor Exposure Signature score, which ticagrelor reproducibly increased in discovery and validation cohorts. Ticagrelor's effects on platelets transcripts positively correlated with effects of P2Y12 inhibition in primary megakaryocytes. In healthy controls, higher baseline scores correlated with lower baseline platelet function and with minor bleeding while receiving ticagrelor. In patients, lower scores independently associated with both the presence and extent of atherosclerosis and incident ischemic events. CONCLUSIONS Ticagrelor-responsive platelet transcripts are a biomarker for platelet function and cardiovascular risk and may have clinical utility for selecting patients with optimal risk:benefit for ticagrelor use.

Abstract
BACKGROUND Patients with minor ischemic stroke or transient ischemic attacks (TIAs) are often treated with dual antiplatelet therapy regimens as part of secondary stroke prevention. Clopidogrel, an antiplatelet used in these regimens, is metabolized into its active form by the CYP2C19 enzyme. Patients with loss of function (LOF) mutations in CYP2C19 are at risk for poorer secondary outcomes when prescribed clopidogrel. AIMS We aimed to determine the cost-effectiveness of three different treatment antiplatelet regimens in ischemic stroke populations with minor strokes or TIAs and how these treatment regimens are influenced by the LOF prevalence in the population. METHODS Markov models were developed to look at the cost-effectiveness of empiric treatment with aspirin and clopidogrel versus empiric treatment with aspirin and ticagrelor, versus genotype-guided therapy for either 21 or 30 days. Effect ratios were obtained from the literature, and incidence rates and costs were obtained from the national data published by the Singapore Ministry of Health. The primary endpoints were the incremental cost-effectiveness ratios (ICERs). RESULTS Empiric treatment with aspirin and ticagrelor was the most cost-effective treatment. Genotype-guided therapy was more cost-effective than empiric aspirin and clopidogrel if the LOF was above 48%. Empiric ticagrelor and aspirin was cost saving when compared to genotype-guided therapy. Results in models of dual antiplatelet therapy for 30 days were similar. CONCLUSION This study suggests that in patients with minor stroke and TIA planned for dual antiplatelet regimens, empiric ticagrelor and aspirin is the most cost-effective treatment regimen. If ticagrelor is not available, genotype-guided therapy is the most cost-effective treatment regimen if the LOF prevalence in the population is more than 48%.

Abstract
INTRODUCTION AND OBJECTIVES Prior studies have not determined whether the effect of dual antiplatelet therapy (DAPT) cessation on the subsequent risk of major adverse cardiac events (MACE) varies by the choice of P2Y12-inhibitor after acute coronary syndrome (ACS). METHODS We performed a prespecified subanalysis of a multicenter, prospective registry of ACS patients discharged on ticagrelor or clopidogrel between 2015 and2019. Nonadherence to DAPT was categorized as physician-guided discontinuation and disruption due to adverse effects, nonadherence, or bleeding. The association between DAPT cessation and 1-year MACE was analyzed using multivariate time-updated Cox models with inverse probability of censoring weighted estimators. RESULTS Out of 2180 patients, 174 (8.3%) prematurely discontinued DAPT (physician-guided, n=126; disruption, n=48). Nonadherent patients were older and had more comorbidities than those on DAPT. Compared with physician-guided discontinuation, disruption occurred earlier after discharge and was more frequent with ticagrelor than with clopidogrel. In time-varying analysis, DAPT cessation was associated with an increased risk of MACE (adjusted HR, 1.32, 95%CI, 1.10-1.76), largely driven by disruption (adjusted HR, 1.47, 95%CI, 1.22-1.73). There was an exponential increase in MACE risk after DAPT cessation within 90 days after ACS, especially after disruption of ticagrelor compared with clopidogrel (Pinteraction<.001). After adjustment for DAPT duration, this interaction was not statistically significant on the additive scale (relative excess risk due to interaction 0.12, 95%CI,-0.99-1.24). CONCLUSIONS In this all-comers registry, 1 in 12 patients prematurely discontinued DAPT within 1 year after ACS. Compared with physician-recommended discontinuation, disruption resulted in a significantly higher risk of MACE. After adjustment for DAPT duration, this association was not moderated by the choice of P2Y12-inhibitor. Clinical trial registered at ClinicalTrials.gov (Identifier: NCT02500290).

Abstract
Importance In patients with acute myocardial infarction (AMI) who have high ischemic risk, data on the efficacy and safety of the de-escalation strategy of switching from ticagrelor to clopidogrel are lacking. Objective To evaluate the outcomes of the de-escalation strategy compared with dual antiplatelet therapy (DAPT) with ticagrelor in stabilized patients with AMI and high ischemic risk following percutaneous coronary intervention (PCI). Design, Setting, and Participants This was a post hoc analysis of the Ticagrelor vs Clopidogrel in Stabilized Patients With Acute Myocardial Infarction (TALOS-AMI) trial, an open-label, assessor-blinded, multicenter, randomized clinical trial. Patients with AMI who had no event during 1 month of ticagrelor-based DAPT after PCI were included. High ischemic risk was defined as having a history of diabetes or chronic kidney disease, multivessel PCI, at least 3 lesions treated, total stent length greater than 60 mm, at least 3 stents implanted, left main PCI, or bifurcation PCI with at least 2 stents. Data were collected from February 14, 2014, to January 21, 2021, and analyzed from December 1, 2021, to June 30, 2022. Intervention Patients were randomly assigned to either de-escalation from ticagrelor to clopidogrel or ticagrelor-based DAPT. Main Outcomes and Measures Ischemic outcomes (composite of cardiovascular death, myocardial infarction, ischemic stroke, ischemia-driven revascularization, or stent thrombosis) and bleeding outcomes (Bleeding Academic Research Consortium type 2, 3, or 5 bleeding) were evaluated. Results Of 2697 patients with AMI (mean [SD] age, 60.0 [11.4] years; 454 [16.8%] female), 1371 (50.8%; 684 assigned to de-escalation and 687 assigned to ticagrelor-based DAPT) had high ischemic risk features and a significantly higher risk of ischemic outcomes than those without high ischemic risk (1326 patients [49.2%], including 665 assigned to de-escalation and 661 assigned to ticagrelor-based DAPT) (hazard ratio [HR], 1.74; 95% CI, 1.15-2.63; P = .01). De-escalation to clopidogrel, compared with ticagrelor-based DAPT, showed no significant difference in ischemic risk across the high ischemic risk group (HR, 0.88; 95% CI, 0.54-1.45; P = .62) and the non-high ischemic risk group (HR, 0.65; 95% CI, 0.33-1.28; P = .21), without heterogeneity (P for interaction = .47). The bleeding risk of the de-escalation group was consistent in both the high ischemic risk group (HR, 0.64; 95% CI, 0.37-1.11; P = .11) and the non-high ischemic risk group (HR, 0.42; 95% CI, 0.24-0.75; P = .003), without heterogeneity (P for interaction = .32). Conclusions and Relevance In stabilized patients with AMI, the ischemic and bleeding outcomes of an unguided de-escalation strategy with clopidogrel compared with a ticagrelor-based DAPT strategy were consistent without significant interaction, regardless of the presence of high ischemic risk.

Abstract
BACKGROUND Patients treated with drug-coated balloons (DCB) have the theoretical advantage of adopting a low-intensity antiplatelet regimen due to the absence of struts and polymers. Nevertheless, the optimal antiplatelet strategy for patients undergoing DCB-only treatment remains a topic of debate and has not been investigated in randomized trials. METHODS The REC-CAGEFREE II is an investigator-initiated, prospective, open-label, multi-center, randomized, non-inferiority trial aimed to enroll 1908 patients from ≥ 40 interventional cardiology centers in China to evaluate the non-inferiority of an antiplatelet regimen consisting of Aspirin plus Ticagrelor for one month, followed by five months Ticagrelor monotherapy, and then Aspirin monotherapy for six months (Experimental group) compared to the conventional treatment of Aspirin plus Ticagrelor for 12 months (Reference group) in patients with acute coronary syndrome (ACS) who have undergone percutaneous coronary intervention (PCI) using paclitaxel-coated balloons (DCB) exclusively. Participants will be randomly assigned to the Experimental or Reference group in a 1:1 ratio. The randomization will be stratified based on the center and the type of lesion being treated (De novo or in-stent restenosis). The primary endpoint is net adverse clinical events (NACE) within 12 months of PCI, which includes the composite of all-cause death, any stroke, any myocardial infarction, any revascularization and Bleeding Academic Research Consortium (BARC) defined type 3 or 5 bleeding. The secondary endpoint, any ischemic and bleeding event, which includes all-cause death, any stroke, MI, BARC-defined type 3 bleeding, any revascularization, and BARC-defined type 2 bleeding events, will be treated as having hierarchical clinical importance in the above order and analyzed using the win ratio method. DISCUSSION The ongoing REC-CAGEFREE II trial aims to assess the efficacy and safety of a low-intensity antiplatelet approach among ACS patients with DCB. If non-inferiority is shown, the novel antiplatelet approach could provide an alternative treatment for ACS patients with DCB. TRIAL REGISTRATION ClinicalTrials.gov identifier: NCT04971356.

Abstract
BACKGROUND There are dated and conflicting data about the optimal timing of initiation of P2Y12 inhibitors in elective percutaneous coronary intervention (PCI). Peri-PCI myocardial necrosis is associated with poor outcomes. We aimed to assess the impact of the P2Y12 inhibitor loading time on periprocedural myocardial necrosis in the population of the randomized Assessment of Loading With the P2Y12 Inhibitor Ticagrelor or Clopidogrel to Halt Ischemic Events in Patients Undergoing Elective Coronary Stenting (ALPHEUS) trial, which compared ticagrelor with clopidogrel in high-risk patients who received elective PCI. METHODS The ALPHEUS trial divided 1809 patients into quartiles of loading time. The ALPHEUS primary outcome was used (type 4 [a or b] myocardial infarction or major myocardial injury) as well as the main secondary outcome (type 4 [a or b] myocardial infarction or any type of myocardial injury). RESULTS Patients in the first quartile group (Q1) presented higher rates of the primary outcome (P = 0.01). When compared with Q1, incidences of the primary outcome decreased in patients with longer loading times (adjusted odds ratio [adjOR], 0.70 [0.52.-0.95]; P = 0.02 for Q2; adjOR 0.65 [0.48-0.88]; P < 0.01 for Q3; adjOR 0.66 [0.49-0.89]; P < 0.01 for Q4). Concordant results were found for the main secondary outcome. There was no interaction with the study drug allocated by randomization (clopidogrel or ticagrelor). Bleeding complications (any bleeding ranging between 4.9% and 7.3% and only 1 major bleeding at 48 hours) and clinical ischemic events were rare and did not differ among groups. CONCLUSIONS In elective PCI, administration of the oral P2Y12 inhibitor at the time of PCI could be associated with more frequent periprocedural myocardial necrosis than an earlier administration. The long-term clinical consequences remain unknown.

Abstract
BACKGROUND AND PURPOSE Ticagrelor is labelled as a reversible, direct-acting platelet P2Y12 receptor (P2Y12 R) antagonist that is indicated clinically for the prevention of thrombotic events in patients with acute coronary syndrome (ACS). As with many antiplatelet drugs, ticagrelor therapy increases bleeding risk in patients, which may require platelet transfusion in emergency situations. The aim of this study was to further examine the reversibility of ticagrelor at the P2Y12 R. EXPERIMENTAL APPROACH Studies were performed in human platelets, with P2Y12 R-stimulated GTPase activity and platelet aggregation assessed. Cell-based bioluminescence resonance energy transfer (BRET) assays were undertaken to assess G protein-subunit activation downstream of P2Y12 R activation. KEY RESULTS Initial studies revealed that a range of P2Y12 R ligands, including ticagrelor, displayed inverse agonist activity at P2Y12 R. Only ticagrelor was resistant to washout and, in human platelet and cell-based assays, washing failed to reverse ticagrelor-dependent inhibition of ADP-stimulated P2Y12 R function. The P2Y12 R agonist 2MeSADP, which was also resistant to washout, was able to effectively compete with ticagrelor. In silico docking revealed that ticagrelor and 2MeSADP penetrated more deeply into the orthosteric binding pocket of the P2Y12 R than other P2Y12 R ligands. CONCLUSION AND IMPLICATIONS Ticagrelor binding to P2Y12 R is prolonged and more akin to that of an irreversible antagonist, especially versus the endogenous P2Y12 R agonist ADP. This study highlights the potential clinical need for novel ticagrelor reversal strategies in patients with spontaneous major bleeding, and for bleeding associated with urgent invasive procedures.

Abstract
The aim of this study was to identify the optimal anti-platelet therapy in older acute coronary syndrome (ACS) patients with a mean age ≥ 60 years by comparing the efficacy and safety of different anti-platelet therapies. The selection of antiplatelet therapy in older patients with ACS is a clinical challenge. Numerous evidences indicate that the de-escalation of dual anti-platelet therapy (DAPT) or P2Y12 inhibitor monotherapy may reduce bleeding risk without increasing thrombotic events. However, there is a lack of systematic reviews and optimal strategy analysis regarding older ACS patients. Randomized controlled trials (RCTs) of anti-platelet therapy in older ACS patients were identified. Major adverse cardiovascular events (MACE) were the primary outcome. Secondary outcomes included all death, cardiovascular death, myocardial infarction, stroke, stent thrombosis, and trial-defined major bleeding. Frequentist and Bayesian network meta-analyses were conducted. Treatments were ranked on posterior probability. Summary odds ratios (ORs) were estimated using Bayesian network meta-analysis. A total of 12 RCTs including 59,284 older ACS patients treated with five anti-platelet strategies were included. Ticagrelor monotherapy after 3 months DAPT was comparable to the other strategies (OR 0.73; 95% CI 0.32-1.6) in terms of MACE risk. Additionally, P score analysis and SUCRA Bayesian analysis showed that it was the most beneficial treatment for all deaths, cardiovascular death and revascularization. For safety, although there was no significant difference in direct comparisons, both SUCRA Bayesian (0.806) and P score (0.519) analysis suggested that ticagrelor monotherapy was the safest strategy. The current evidence demonstrated that ticagrelor monotherapy after 3 months DAPT may be a promising approach for achieving a more favorable balance between risk and benefit for older ACS patients, with a relatively low bleeding risk and without an increased risk of MACE events. Moreover, it remains the preferred option for clinical outcomes such as all death, CV death and revascularization. Further high-quality and long-term studies are required to validate anti-platelet therapies among older ACS patients.

Abstract
PURPOSE P2Y12 inhibitors (P2Y12i) reduce cardiac events after acute coronary syndromes (ACS). However, suboptimal P2Y12i adherence persists. We aimed to examine P2Y12i non-adherence using group-based trajectory methods and to identify adherence predictors. METHODS We conducted a population-based, retrospective cohort study using administrative data in Ontario, Canada of patients ≥65 years admitted for ACS between April 2014 and March 2018 with a P2Y12i dispensed within 7 days of discharge. We used group-based trajectory models to characterize longitudinal 1-year adherence patterns. Predictors associated with each adherence trajectory were identified by multinomial logistic regression. RESULTS We included 11 917 patients using clopidogrel and 9763 using ticagrelor, aged [mean ± SD]: 77.33 ± 8.31/73.59 ± 6.79 years; men: 56.2%/65.4%, respectively. We identified 3 longitudinal adherence trajectories, that differed by agent: 75% of clopidogrel and 68% of ticagrelor patients showed a consistently adherent trajectory, while 13%/17% were gradually, and 12%/15% were rapidly non-adherent, respectively (p < 0.001). Differing baseline characteristics in each cohort were associated with observed adherence trajectories. Concomitant atrial fibrillation and prior bleeding history were associated with non-adherence among clopidogrel users. Among ticagrelor users, women and older persons were more likely to be rapidly non-adherent, adherence declining steeply starting 1 month post-ACS. CONCLUSIONS We identified distinct adherence trajectories for clopidogrel and ticagrelor post-ACS, with 3 out of 4 clopidogrel patients but only 2 out of 3 ticagrelor patients in the consistently adherent trajectory. Intensive interventions targeted to the period of steep adherence decline post-ACS, particularly for women and older persons initiating ticagrelor, and patients with atrial fibrillation on clopidogrel should be considered and investigated further.

Abstract
Current guidelines recommend individualizing the choice and duration of P2Y12 inhibitor therapy based on the trade-off between bleeding and ischemic risk. However, whether a potent P2Y12 inhibitor (ticagrelor) or a less potent one (clopidogrel) is more appropriate in patients with acute coronary syndrome (ACS) in the setting of high bleeding or ischemic risk is not clear. The study aimed to compare the clinical outcomes of clopidogrel and ticagrelor in patients with ACS at high bleeding or ischemic risk. A total of 5,713 patients with ACS were included in this retrospective study. The Cox proportional hazard regression model was adjusted by applying the inverse probability weighted approach to reduce treatment selection bias. The primary clinical outcome was all-cause death. Secondary outcomes included in-hospital death, ACS, target vessel revascularization, stent thrombosis, stroke, or clinically significant or major bleeding. The median follow-up duration was 53.6 months. After multivariable Cox model using an inverse probability weighted approach, all-cause death in the overall population and subgroups of patients at high bleeding risk, and/or at high ischemic risk were not significantly different between clopidogrel and ticagrelor. Rates for secondary outcomes were also similar between the groups. In conclusion, ticagrelor and clopidogrel are associated with comparable clinical outcomes in patients with ACS irrespective of bleeding and ischemic risk.

Abstract
Background Dual antiplatelet therapy with a P2Y12 inhibitor (e.g., clopidogrel and ticagrelor) and aspirin is recommended for at least one year after percutaneous coronary intervention (PCI) to prevent further myocardial infarction and stent thrombosis as the major adverse effects of PCI. Methods This randomized clinical trial was conducted from October 2022 to March 2023. Patients who had undergone elective PCI were included in the study. Patients were randomized into two different groups. One group took ASA 80 mg and clopidogrel 75 mg once daily, while the other took ASA 80 mg once daily and ticagrelor 90 mg twice daily. After six months of close follow-up, patients were asked to score their dyspnea on a 10-point Likert scale. They were also asked about dyspnea on exertion, paroxysmal nocturnal dyspnea (PND), bleeding, and the occurrence of major adverse cardiovascular events (MACEs). Results 223 patients were allocated to the clopidogrel group and 214 to the ticagrelor group. In the ticagrelor group, 95 patients (44.3%) reported dyspnea at rest, compared with only 44 patients (19.7%) in the clopidogrel group (P < 0.001). MACEs occurred in 7 patients (2.8%) in the ticagrelor group, compared with 16 (7.6%) in the clopidogrel group (P = 0.031). Eight patients (3.8%) reported bleeding with ticagrelor, as did seven (3.2%) with clopidogrel (P = 0.799). Conclusions New-onset dyspnea was recorded more frequently with ticagrelor than clopidogrel, yet fewer MACEs occurred with ticagrelor (ClinicalTrials.gov number: NCT05858918).

Abstract
OBJECTIVE To compare the effects of ticagrelor and prasugrel on absolute coronary blood flow (Q) and microvascular resistance (R) in patients with stable coronary artery disease (CAD) treated with elective percutaneous coronary intervention (PCI) (NCT05643586). Besides being at least as effective as prasugrel in inhibiting platelet aggregation, ticagrelor has been shown to have additional properties potentially affecting coronary microcirculation. METHODS We randomly assigned 50 patients to ticagrelor (180 mg) or prasugrel (60 mg) at least 12 hours before intervention. Continuous thermodilution was used to measure Q and R before and after PCI. Platelet reactivity was measured before PCI. Troponin I was measured before, 8 and 24 hours after PCI. RESULTS At baseline, fractional flow reserve, Q and R were similar in two study groups. Patients in the ticagrelor group showed higher post-PCI Q (242±49 vs 205±53 mL/min, p=0.015) and lower R values (311 (263, 366) vs 362 (319, 382) mm Hg/L/min, p=0.032). Platelet reactivity showed a negative correlation with periprocedural variation of Q values (r=-0.582, p<0.001) and a positive correlation with periprocedural variation of R values (r=0.645, p<0.001). The periprocedural increase in high-sensitivity troponin I was significantly lower in the ticagrelor compared with the prasugrel group (5 (4, 9) ng/mL vs 14 (10, 24) ng/mL, p<0.001). CONCLUSIONS In patients with stable CAD undergoing PCI, pretreatment with a loading dose of ticagrelor compared with prasugrel improves post-procedural coronary flow and microvascular function and seems to reduce the related myocardial injury.

Abstract
BACKGROUND The benefits of de-escalation of P2Y12 inhibition after percutaneous coronary intervention (PCI) may differ by high bleeding risk (HBR) status. AIMS We investigated the efficacy and safety of de-escalation from ticagrelor to clopidogrel after PCI by HBR status. METHODS This is a non-prespecified post hoc analysis of the TicAgrelor Versus CLOpidogrel in Stabilized Patients with Acute Myocardial Infarction (TALOS-AMI) trial. Net adverse clinical events (a composite of cardiovascular death, myocardial infarction, stroke, or Bleeding Academic Research Consortium [BARC] bleeding type 2, 3, or 5) at 1 year post-PCI were compared between the de-escalation (clopidogrel plus aspirin) and the active control (ticagrelor plus aspirin) groups by HBR status, as defined by the modification of the Academic Research Consortium (ARC) criteria. RESULTS A total of 2,625 patients in the TALOS-AMI trial were analysed. Of these, 589 (22.4%) met the modified ARC-HBR criteria. The de-escalation group had lower primary endpoint rates than the control group in both HBR (hazard ratio [HR] 0.47, 95% confidence interval [CI]: 0.26-0.84) and non-HBR (HR 0.59, 95% CI: 0.41-0.84) patients. There were no differences in treatment effect for the primary endpoint regardless of HBR status (p for interaction=0.904). BARC bleeding type 3 or 5 was less common in the de-escalation than the control group among HBR patients only (HR 0.24, 95% CI: 0.07-0.84). CONCLUSIONS In stabilised acute myocardial infarction patients, unguided de-escalation from ticagrelor to clopidogrel was associated with a lower rate of net adverse clinical outcomes irrespective of HBR status. The effect of de-escalation of P2Y12 inhibition on reducing haemorrhagic events was greater in patients with HBR.

Abstract
BACKGROUND A systematic review and network meta-analysis (NMA) were conducted to explore the efficacy and safety of different antiplatelet or anticoagulation drugs in chronic coronary syndromes patients. METHODS Electronic databases (Pubmed, Embase and Cochrane databases) were systematically searched to identify randomized controlled trials evaluating different antiplatelet or anticoagulation drugs (aspirin, aspirin + clopidogrel, aspirin + clopidogrel + cilostazol, clopidogrel/prasugrel + aspirin, aspirin + rivaoxaban 2.5 mg, aspirin + ticagrelor 60 mg, aspirin + ticagrelor 90 mg, clopidogrel or rivroxaban 5 mg) versus placebo for treatment chronic coronary syndromes patients. Outcomes included major adverse cardiovascular events, all cause death, major bleeding and myocardial infarction. A random-effect Bayesian NMA was conducted for outcomes of interest, and results were presented as odds ratios (ORs) and 95% credible intervals. The NMA was performed using R Software with a GeMTC package. A Bayesian NMA was performed and relative ranking of agents was assessed using surface under the cumulative ranking probabilities. RESULTS Ten randomized controlled trials met criteria for inclusion and finally included in this NMA. In head-to-head comparison, no significant difference was observed between all antithrombotic treatment strategies with respect to primary endpoint of major adverse cardiovascular events. In head-to-head comparison, no significant difference was observed between all antithrombotic treatment strategies with respect to all cause death. Clopidogrel/prasugrel + aspirin (OR = 3.8, 95% credible intervals [CrI]: 1.3-12.0, P < .05) and aspirin + rivaroxaban 2.5 mg (OR = 3.1, 95%CrI: 1.1-9.5, P < .05) was associated with an increase of the major bleeding. Compared with aspirin alone, aspirin + clopidogrel (OR = 0.42, 95%CrI: 0.22-0.76, P < .05) and aspirin + ticagrelor 90 mg (OR = 0.42, 95%CrI: 0.17-0.95, P < .05) was associated with a decrease of the myocardial infarction. CONCLUSIONS Myocardial infarction was significantly lower when adding clopidogrel or ticagrelor 90 mg to aspirin than those in the aspirin alone group. However, clopidogrel/prasugrel and rivaroxaban 2.5 mg was associated with an increase of the major bleeding than aspirin alone.

Abstract
Repeat coronary revascularization is a common adverse event after successful percutaneous coronary intervention. This analysis aimed to assess the effects of ticagrelor monotherapy on repeat clinically driven revascularization (CDR). In the TWILIGHT (Ticagrelor With Aspirin or Alone in High-Risk Patients after Coronary Intervention) trial, after 3 months of ticagrelor plus aspirin, high-risk patients were maintained on ticagrelor and randomly allocated to aspirin or placebo for 1 year. The primary end point of this analysis was CDR within 12 months after randomization. The key secondary end points were major adverse cardiovascular and cerebrovascular events (MACCEs), a composite of all-cause death, myocardial infarction, stroke, or CDR, and net adverse clinical events (NACEs), including the individual components of MACCEs and clinically relevant bleeding. The analysis was performed in the per-protocol population. CDR occurred in 473 of 7,039 patients and was associated with a significantly higher risk of subsequent all-cause death, myocardial infarction, or stroke (adjusted hazard ratios [HRs] 2.92, 95% confidence interval [CI] 1.82 to 4.67). Ticagrelor monotherapy was associated with a similar 12-month risk of CDR (7.1% vs 6.6%; HR 1.09, 95% CI 0.90 to 1.30, p = 0.363) and MACCEs (8.9% vs 8.6%; HR 1.04, 95% CI 0.89 to 1.22, p = 0.619), and a lower risk of NACEs (12.2% vs 14.6%; HR 0.83 95% CI 0.73 to 0.94, p = 0.004) than ticagrelor plus aspirin. In conclusion, among high-risk patients who underwent percutaneous coronary intervention, ticagrelor monotherapy after 3 months of ticagrelor-based dual antiplatelet therapy was associated with a similar risk of CDR and MACCEs and a decrease of NACEs (TWILIGHT: NCT02270242).

Abstract
Identifying the most appropriate antiplatelet therapy for each patient to prevent ischemic events while minimizing the risk of bleeding is an integral part of the short- and long-term management of patients with coronary artery disease (CAD). This review aims to summarize the available evidence on the contemporary use of P2Y12 inhibitors in CAD patients, focusing on strategies aimed at providing adequate ischemic protection while preventing bleeding risk through dual antiplatelet therapy (DAPT) modulation. Randomized trials and observational studies have been reviewed to determine the most appropriate antiplatelet treatment for CAD patients with different risk profiles. Both ischemic and bleeding events have a significant prognostic impact and should be carefully considered in clinical decision-making. Current guidelines recommend the use of third-generation PY2Y12 inhibitors (prasugrel or ticagrelor) over clopidogrel, as a part of DAPT, in patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention. Newer P2Y12 inhibitors have a more rapid onset of action and less interindividual variability in platelet inhibition than clopidogrel but are associated with an increased risk of bleeding that may limit their benefit. Importantly, the anti-ischemic benefit of ticagrelor and prasugrel is mainly observed in the first weeks after ACS, whereas clopidogrel seems to provide the best balance between ischemic protection and bleeding as long-term maintenance therapy. These concepts support DAPT modulation after the acute phase, by de-escalating from full-dose to low-dose newer P2Y12 inhibitors, by switching to clopidogrel, or by early withdrawing aspirin to maximize both the efficacy and safety of antiplatelet therapy in patients with CAD.

Abstract
Choosing optimal P2Y12 inhibitor in frail older adults is challenging because they are at increased risk of both ischemic and bleeding events. We conducted a retrospective cohort study of Medicare Advantage Plan beneficiaries who were prescribed clopidogrel, prasugrel, or ticagrelor after percutaneous coronary intervention-treated ST-elevation myocardial infarction from January 1, 2010 to December 31, 2020. Frailty was defined using claims-based frailty index ≥0.25. We conducted multivariable logistic regression to identify factors associated with using potent P2Y12 inhibitors and multivariable-adjusted competing risk analyses to compare the rate of discontinuation of potent P2Y12 inhibitors in frail versus non-frail patients. There were 11,239 patients (mean age 74 years, 39% women). The prevalence of cardiovascular and geriatric co-morbidities was as follows: 32% chronic kidney disease, 28% heart failure, 10% previous myocardial infarction, 6% dementia, 20% anemia, and 12% frailty. The proportion of patients receiving clopidogrel decreased from 78.3% in 2010 to 2013 to 42.1% in 2018 to 2020, with a concurrent increase in those receiving potent P2Y12 inhibitors (mostly ticagrelor) from 21.7% to 57.9%. Frailty was independently associated with reduced odds of initiation (odds ratio 0.78, 95% confidence interval 0.67 to 0.90) but not with discontinuation of potent P2Y12 inhibitors (subdistribution hazard ratio 1.09, 95% confidence interval 0.98 to 1.22). In conclusion, frail older adults are less likely to receive potent P2Y12 inhibitors after percutaneous coronary intervention-treated ST-elevation myocardial infarction, but they are as likely as non-frail patients to continue with the prescribed P2Y12 inhibitor.

Abstract
Limited data comparing prasugrel and ticagrelor in acute coronary syndrome are available. Online databases, including MEDLINE and Cochrane Central, were queried to compare these drugs. The primary outcomes of this meta-analysis are myocardial infarction (MI), all-cause mortality, cardiovascular mortality, noncardiovascular mortality, stent thrombosis, and stroke. The secondary outcome is major bleeding. A total of 9 studies, including 94,590 patients (prasugrel group = 32,759; ticagrelor group = 61,831), were included in this meta-analysis. The overall mean age was 62.73 years, whereas the mean age for the ticagrelor and prasugrel groups was 63.80 and 61.65 years, respectively. Prasugrel is equally effective as compared with ticagrelor in preventing MI. There was no difference between the 2 groups regarding all-cause mortality, stent thrombosis, stroke, or major bleeding. In patients with acute coronary syndrome, prasugrel is equally effective when compared with ticagrelor in preventing MI.

Abstract
It is unknown whether there are age- and gender-related differences in the safety and efficacy of potent P2Y12 inhibitors in East Asian populations with a different bleeding or ischemic propensity. Using data from the TICAKOREA (Ticagrelor Versus Clopidogrel in Asian/Korean Patients with ACS Intended for Invasive Management) trial comparing ticagrelor versus clopidogrel for 800 Korean patients with acute coronary syndrome, the safety and efficacy outcomes were compared according to age (<75 vs ≥75 years) and gender (men vs women). The primary bleeding end point was clinically significant bleeding, and the primary ischemic end point was a major adverse cardiovascular event (MACE) at 12 months. The incidences of clinically significant bleeding were significantly higher after ticagrelor than after clopidogrel in patients aged <75 years (adjusted hazard ratio [HR] 2.56, 95% confidence interval [CI] 1.40 to 4.67) but not in patients aged ≥75 years (adjusted HR 1.1, 95% CI 0.40 to 3.38). The incidences of MACEs were significantly higher after ticagrelor than after clopidogrel in patients aged ≥75 years (adjusted HR 6.14, 95% CI 1.40 to 26.90) but not in patients aged <75 years (adjusted HR 0.93, 95% CI 0.50 to 1.73). The incidences of clinically significant bleeding were significantly higher after ticagrelor than after clopidogrel in men (adjusted HR 2.69, 95% CI 1.38 to 5.24) but not in women (adjusted HR 1.49, 95% CI 0.64 to 3.46). The adjusted risks of MACEs after ticagrelor or clopidogrel were not significantly different between men and women. In conclusion, there were substantial age- and gender-related differences in bleeding and ischemic outcomes after ticagrelor or clopidogrel in Korean patients with acute coronary syndrome.

Abstract
Background This study aimed to investigate the efficacy and safety of ticagrelor-aspirin versus clopidogrel-aspirin in Chinese patients by the presence and clinical presentation of intracranial artery stenosis (ICAS) using randomized trial data from the CHANCE-2 (Clopidogrel in High-Risk Patients With Acute Nondisabling Cerebrovascular Events-II) trial. Methods and Results A total of 6412 patients with minor stroke or transient ischemic attack who carried CYP2C19 loss-of-function alleles were randomized to either the ticagrelor-aspirin or clopidogrel-aspirin group. Patients without imaging of the intracranial artery were excluded from the nonprespecified subgroup analysis of CHANCE-2. All patients included were classified into the following groups: without ICAS, symptomatic ICAS, or asymptomatic ICAS. The primary efficacy outcome was new strokes within 90 days. There were 5893 patients (median age, 64.8 years; 33.9% women) included, and 172 (4.9%), 171 (10.5%), and 57 (7.7%) cases of new strokes occurred within 90 days in the without ICAS, with symptomatic ICAS, and with asymptomatic ICAS groups, respectively. Ticagrelor-aspirin was associated with reduced risk of new stroke in patients without ICAS (62 [3.5%] versus 110 [6.3%]; hazard ratio [HR], 0.57 [95% CI, 0.41-0.78]) but not in those with symptomatic ICAS (HR, 0.77 [95% CI, 0.56-1.05]) or in those with asymptomatic ICAS (HR, 0.77 [95% CI, 0.43-1.38]) compared with clopidogrel-aspirin (P for interaction=0.14). There were no significant differences in the proportion of severe or moderate bleeding events among different ICAS groups. Conclusions Patients without ICAS received a significantly greater benefit from ticagrelor-aspirin than clopidogrel-aspirin after minor ischemic stroke or transient ischemic attack, and there was no statistically significant difference between treatments in patients with symptomatic ICAS or asymptomatic ICAS.

Abstract
INTRO SARS-CoV-2 (COVID-19) infection is associated with acute ischemic stroke (AIS), which may be due to a prothrombotic state. Early reports have suggested high rates of reocclusion following mechanical thrombectomy (MT) with poor radiographic and clinical outcomes. We report our early experience using intra-procedural antithrombotics to address SARS-CoV-2 reocclusion. METHODS We identified 6 patients that experienced early reocclusion after MT for COVID-19-associated AIS through retrospective chart review abstracting their basic demographics, COVID-19 status, and stroke management. All these patients were treated after reocclusion with aspirin and cangrelor intra-procedurally, the latter of which was converted to ticagrelor post-procedurally. Some patients additionally received argatroban infusion intraprocedurally. RESULTS Mean age was 54. There were 3 post-procedural and 3 intra-procedural re-occlusions. After repeat thrombectomy and treatment with aspirin and cangrelor, those with post-procedure reocclusion did not show further reocclusion, while those with intra-procedural reocclusion showed radiographic improvement with intraprocedural cangrelor administration. Outcomes for these patients were poor, with a median mRS of 4. Two patients developed petechial hemorrhage of their stroke which was managed conservatively, and one developed a retroperitoneal hemorrhage from femoral access requiring transfusion. There were no patients who developed new parenchymal hematomas. CONCLUSION COVID-19 AIS may be associated with a hypercoagulable state which risks malignant reocclusion complicating MT. We found antithrombotic treatment periprocedural cangrelor with or without argatroban transitioned to oral aspirin with ticagrelor to be a viable method for management of these patients.

PATIENTS AND METHODS A total of 80 STEMI patients admitted to our hospital from February 2020 to March 2023 were selected and included in the retrospective study, all receiving PCI treatment. They were randomly and retrospectively divided into a control group (40 cases) and an observation group (40 cases), and treated with clopidogrel and ticagrelor, respectively. The clinical effects were compared. RESULTS The starting perfusion time of the contrast agent in the myocardial infarction area in the observation group was 2.22±0.27 s, and the peak perfusion time was 2.62±0.27 s, which was lower than those in the control group (2.51±0.29 s and 3.21±0.39 s, t=4.629, 7.867, p=0.000). The ratio of peak perfusion intensity between the two groups was significantly different (t=2.363, p=0.021). Left ventricular ejection fraction, stroke volume index, and cardiac index in the observation group were higher than those in the control group (55.03±6.03 vs. 52.33±5.13; 57.39±6.81 vs. 51.11±6.31 L/min·m-2; 3.49±0.45 vs. 3.12±0.38 mL/m2, t=2.157, 4.278, 3.973, p<0.05). The observation group had lower levels of brain natriuretic peptide and C-reactive protein compared to the control group (425.35±55.71 vs. 589.36±70.24 pg/mL; 15.13±1.03 vs. 21.64±2.74 mg/L; t=11.570, 14.066, p=0.000). There was no statistical significance in the incidence of adverse cardiovascular events between the two groups (2.50% vs. 7.50%, χ2=1.920, p=0.166). CONCLUSIONS The use of ticagrelor can regulate myocardial microcirculation and improve cardiac function in STEMI patients undergoing PCI.

Abstract
As a part of dual antiplatelet therapy (DAPT), prasugrel or ticagrelor is prescribed along with aspirin to patients of acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI). We aimed to assess if the PRECISE-DAPT score, which provides prediction of bleeding during DAPT, could be used to choose between prasugrel and ticagrelor for DAPT initiation. 181 patients out of which 71 received prasugrel and 110 received ticagrelor were enrolled in this prospective cohort study. PRECISE-DAPT score was calculated for everyone and was used to dichotomize patients into two subgroups (score <25 and ≥25). After balancing potential confounders in baseline characteristics of the subgroups using propensity scores, comparison of a composite outcome of 4-point major adverse cardiovascular events (4P-MACE) (i.e., cardiovascular death, non-fatal myocardial infarction, non-fatal stroke, or coronary revascularization due to stent thrombosis) and bleeding (any type as defined by the Bleeding Academic Research Consortium) within 1-year post-PCI was performed among the subgroups using Cox proportional hazards regression. Prasugrel was associated with lower and comparatively higher 4P-MACE events in subgroups with score ≥25 (HR: 0.17; 95% CI, 0.04-0.77) and score <25 (HR: 3.58; 95% CI, 0.62-20.70) respectively. For bleeding outcome, prasugrel trended towards more clinical benefit for scores ≥25 (HR: 0.44; 95% CI, 0.10-1.93) than <25 (HR: 0.93; 95% CI, 0.13-6.58). Therefore, prasugrel was associated with better clinical effectiveness and trended towards a lower bleeding risk compared to ticagrelor within 1-year post-PCI for those with a high PRECISE-DAPT score (≥25). This finding requires validation through larger studies.
