Abstract
Ticagrelor is a platelet P2Y12 receptor inhibitor approved for use in patients with acute coronary syndromes, coronary artery disease, and low-moderate risk acute ischemic stroke or high-risk transient ischemic attack. Clinical trials have evaluated the efficacy and safety of ticagrelor on ischemic and bleeding outcomes for different indications and with varying treatment approaches. As a result, there is a large body of clinical evidence demonstrating different degrees of net clinical benefit compared with other platelet inhibitor drugs based on indication, patient characteristics, clinical presentation, treatment duration, and other factors. We provide a review of the major trials of ticagrelor in the context of other randomized trials of clopidogrel and prasugrel to organize the volume of available information, elevate corroborating and conflicting data, and identify potential gaps as areas for further exploration of optimal antiplatelet treatment.

Abstract
The management of low-risk differentiated thyroid cancer (DTC) has evolved over time toward treatment de-escalation. However, overtreatment with supraphysiological dose of levothyroxine (LT4) continues to be observed despite current clinical guideline. This study aimed to assess the actual thyrotropin suppressive therapy for low-risk DTC patients at an endocrine center in Bangkok. This retrospective study included patients with low-risk DTC who were regularly follow-up for at least 18 months at Theptarin Hospital between 2016 and 2022. The serum thyroid stimulating hormone (TSH) levels were stratified as TSH < 0.1 mIU/L; TSH 0.1 to 0.5 mIU/L; TSH 0.5 to 2.0 mIU/L; and TSH > 2.0 mIU/L. The initial risk stratification (IRS) and dynamic risk stratification were determined at 12 months of follow-up after completing the initial treatment and at the last visit. The clinical factors associated with overtreatment with LT4 were analyzed. A total of 102 patients (83.3% female, age at diagnosis 41.8 ± 13.6 years, mean tumor size 1.6 ± 1.0 cm) were evaluated with a mean follow-up of 5.9 years. The IRS classified 92.2% of patients after the initial treatment and 93.1% of patients at the last follow-up visit into the excellent response category. The mean LT4 daily dosage at the last follow-up was 121.3 ± 44.8 µg/day. Serum TSH levels were in an appropriate target range according to IRS in only 8.8% (9/102) of the patients and then improved to 19.6% (20/102) at the last follow-up visit. Further analysis showed that treating physicians with ≥10 years of practice was associated with severe TSH suppression therapy (TSH < 0.1 mIU/L). Despite the current clinical guideline recommendations and scientific evidences, less than one-fifth of low-risk DTC patients achieved the appropriate serum TSH target. While the proportion of an optimum LT4 suppressive had improved during the study period, further efforts are needed to overcome this clinical inertia.

Abstract
OBJECTIVES To compare dual antiplatelet therapy (DAPT) de-escalation with five alternative DAPT strategies in patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI). DESIGN We conducted a systematic review and network meta-analysis (NMA). Parallel-arm randomised controlled trials (RCTs) comparing DAPT strategies were included and arms of interest were compared via NMA. Partial ranking of each identified arm and for each investigated endpoint was also performed. SETTING AND PARTICIPANTS Adult patients with ACS (≥18 years) undergoing PCI with indications for DAPT. SEARCH METHODS A comprehensive search covered several databases (PubMed, Embase, Cochrane Central, MEDLINE, Conference Proceeding Citation Index-Science) from inception to 15 October 2023. Medical subject headings and keywords related to ACS, PCI and DAPT interventions were used. Reference lists of included studies were screened. Clinical trials registers were searched for ongoing or unpublished trials. INTERVENTIONS Six strategies were assessed: T1 arm: acetylsalicylic acid (ASA) and prasugrel for 12 months; T2 arm: ASA and low-dose prasugrel for 12 months; T3 arm: ASA and ticagrelor for 12 months; T4 arm: DAPT de-escalation (ASA+P2Y12 inhibitor for 1-3 months, then single antiplatelet therapy with potent P2Y12 inhibitor or DAPT with clopidogrel); T5 arm: ASA and clopidogrel for 12 months; T6 arm: ASA and clopidogrel for 3-6 months. MAIN OUTCOME MEASURES Primary outcome: Cardiovascular mortality. SECONDARY OUTCOMES bleeding events (all, major, minor), stent thrombosis (ST), stroke, myocardial infarction (MI), all-cause mortality, major adverse cardiovascular events (MACE). RESULTS 23 RCTs (75 064 patients with ACS) were included. No differences in cardiovascular mortality, all-cause death, recurrent MI or MACE were found when the six strategies were compared, although with different levels of certainty of evidence. ASA and clopidogrel for 12 or 3-6 months may result in a large increase of ST risk versus ASA plus full-dose prasugrel (OR 2.00, 95% CI 1.14 to 3.12, and OR 3.42, 95% CI 1.33 to 7.26, respectively; low certainty evidence for both comparisons). DAPT de-escalation probably results in a reduced risk of all bleedings compared with ASA plus full-dose 12-month prasugrel (OR 0.49, 95% CI 0.26 to 0.81, moderate-certainty evidence) and ASA plus 12-month ticagrelor (OR 0.52, 95% CI 0.33 to 0.75), while it may not increase the risk of ST. ASA plus 12-month clopidogrel may reduce all bleedings versus ASA plus full-dose 12-month prasugrel (OR 0.66, 95% CI 0.42 to 0.94, low certainty) and ASA plus 12-month ticagrelor (OR 0.70, 95% CI 0.52 to 0.89). CONCLUSIONS DAPT de-escalation and ASA-clopidogrel regimens may reduce bleeding events compared with 12 months ASA and potent P2Y12 inhibitors. 3-6 months or 12-month aspirin-clopidogrel may increase ST risk compared with 12-month aspirin plus potent P2Y12 inhibitors, while DAPT de-escalation probably does not.

Eur J Clin Pharmacol 2024; 80:759-770.

Abstract
OBJECTIVE This retrospective study aimed to investigate the potential impact of ticagrelor and clopidogrel treatment on cardiovascular outcomes in patients with anemia and acute coronary syndrome (ACS) and to provide insights into the optimal therapeutic approach for this vulnerable patient population. METHODS A retrospective research design was employed, involving patients diagnosed with ST-segment elevation myocardial infarction (STEMI) or non-ST-segment elevation myocardial infarction (NSTEMI) between 2014 and 2021. Inclusion criteria required a hemoglobin level below 12 mg/dL and a minimum 12-month P2Y12 inhibitor treatment. Comprehensive clinical, biochemical, and echocardiographic data were collected from the hospital's electronic repository. The primary efficacy endpoint was major adverse cardiovascular events (MACE), encompassing total mortality, cardiovascular mortality, reinfarction, ischemic stroke, and hemorrhagic stroke. Major hemorrhage was the primary safety endpoint. Secondary outcomes included total mortality, cardiovascular mortality, reinfarction, ischemic stroke, and hemorrhagic stroke, individually. RESULTS Patients treated with ticagrelor (n = 118) and clopidogrel (n = 538) were compared. No significant difference was observed in major adverse cardiovascular events (MACE) and major bleeding between ticagrelor and clopidogrel treatment groups (MACE: clopidogrel 10.0% vs. ticagrelor 11.0%, p = 0.75; major bleeding: clopidogrel 2.8%, ticagrelor 2.5%, p = 0.88). Patients with hemoglobin levels ≤ 8 mg/dL demonstrated significantly higher MACE and major bleeding rates in the ticagrelor group (p = 0.008 and p = 0.002, respectively). Among patients aged ≥ 75 years, ticagrelor treatment was associated with a higher risk of major bleeding (p = 0.04). CONCLUSIONS Ticagrelor and clopidogrel exhibited comparable efficacy and safety outcomes in anemic ACS patients over a one-year period. Although ticagrelor demonstrated superiority in reducing ischemic events, it is crucial to recognize the limitations of retrospective studies in informing clinical practice. This study offers valuable insights into tailoring antiplatelet therapy for anemic ACS patients and provides guidance for personalized treatment strategies, acknowledging the hypothesis-generating nature of retrospective analyses.

Abstract
Background Balancing the effects of dual antiplatelet therapy (DAPT) in the era of potent purinergic receptor type Y, subtype 12 (P2Y12) inhibitors remains a challenge in the management of acute coronary syndrome (ACS). Methods We conducted a systematic review and meta-analysis following a 2-stage process consisting of searching for systematic reviews published between 2019 and November 2022. We included randomized controlled trials (RCTs) of ACS patients treated with percutaneous coronary intervention comparing (i) ticagrelor- vs prasugrel-based DAPT and (ii) P2Y12 inhibitor de-escalation strategies. Outcomes of interest were major adverse cardiovascular events (MACE), all-cause death, stent thrombosis, and major bleeding. We estimated risk ratios (RRs) and 95% confidence intervals (CIs) using a random-effects model. Results Eight RCTs (n = 5571) compared ticagrelor to prasugrel. Ticagrelor was associated with an increased risk of MACE compared to prasugrel (RR 1.23, 95% CI 1.01-1.49, moderate certainty), without significant differences in death, stent thrombosis, or major bleeding. In 2 RCTs (n = 3343) comparing clopidogrel-based DAPT de-escalation after 1 month to potent P2Y12 inhibitor-based DAPT continuation, clopidogrel de-escalation did not significantly alter the incidence of MACE, death, or stent thrombosis, but reduced that of major bleeding (RR 0.51, 95% CI 0.28-0.92, high certainty). The effect of prasugrel dose de-escalation was inconclusive for all outcomes based on one trial. Conclusions Ticagrelor was associated with an increase in MACE compared with prasugrel, based on low-certainty evidence, whereas de-escalation to clopidogrel after 1 month of potent P2Y12 inhibitor was associated with a decrease in incidence of major bleeding without increasing thrombotic outcomes in ACS patients post-percutaneous coronary intervention.

Abstract
Dual antiplatelet therapy-the combination of aspirin and a P2Y12 inhibitor-remains the standard antiplatelet regimen recommended to prevent ischemic complications immediately after percutaneous coronary intervention. Nonetheless, recent advances in stent technologies, percutaneous coronary intervention techniques, adjunctive pharmacotherapy for secondary prevention, and the rising awareness of the prognostic impact of bleeding, which are inevitably associated with dual antiplatelet therapy, led to the investigation of alternative antiplatelet regimens related to fewer bleeding and a preserved ischemic protection. Thrombotic complications occur mostly in the first months after percutaneous coronary intervention, while the risk of bleeding remains stable over time; this observation laid the foundation of the concept of antiplatelet de-escalation, consisting of a more intense antiplatelet regimen early after percutaneous coronary intervention, followed by a less potent antiplatelet therapy thereafter. According to new definitions proposed by the Academic Research Consortium, de-escalation can be achieved by discontinuation of 1 antiplatelet agent, switching from a potent P2Y12 inhibitor to clopidogrel, or by reducing the dose of antiplatelet agents. This review discusses the rationale and the evidence supporting antiplatelet de-escalation, provides practical guidance to use these new regimens, and gives insights into future developments in the field.

Abstract
BACKGROUND AND OBJECTIVE Recent research indicates a correlation between plasma concentration of P2Y12 inhibitors and clinical events, particularly bleeding, which significantly impeded their clinical therapeutic performance. It is therefore vital to delve into the factors that might affect the plasma concentration. The study aims to summarize population pharmacokinetics/pharmacodynamics (PopPKPD) models for commonly prescribed P2Y12 inhibitors (clopidogrel, prasugrel, and ticagrelor) and assess bleeding risk in specific individual groups. METHODS The PopPKPD models of P2Y12 inhibitors were collected and summarized based on predetermined inclusion and exclusion criteria. The collected models were replicated in simulations, which were used to assess factors affecting plasma concentrations of P2Y12 inhibitors. Simulation results for special populations were compared to therapeutic window based on reported exposure-effect relationships (PK/PD-related bleeding and thrombotic clinical outcomes) to predict bleeding risk in special populations with different dosing regimens and cumulative covariates. RESULT Finally, 12 studies were included for PK simulation, 7 of which that also included PD data were subjected to further analysis, with the majority being based on Phase I or II trials. Simulations showed that several covariates such as female gender, weight, elderly can significantly impact on exposure, with special populations reaching up to 179% of the general population. However, after dose adjustment, blood concentrations for special populations can reach approximately ±20% of general population exposure. Therefore, lowering the maintenance dose of ticagrelor from 90 to 60 mg bid was first recommended to reduce bleeding risk without significantly increasing ischemic risk, particularly in elderly, small-weight Asian females. CONCLUSION Lowering the maintenance dose of ticagrelor from 90 to 60 mg bid effectively reduces bleeding risk without increasing thrombotic infarction risk in elderly, small-weight Asian females.

CARDIOVASCULAR PHARMACOTHERAPY 2024; 10:158-169.

Abstract
AIMS Randomized controlled trials (RCTs) testing bleeding reduction strategies using antiplatelet treatment regimens (BRATs) in acute coronary syndromes (ACS) have shown promising results, but the generalizability of these findings may be significantly influenced by the ethnicity of the patients enrolled, given that East Asian (EA) patients show different ischaemic-bleeding risk profile compared to non-EA patients. METHODS AND RESULTS RCTs comparing a BRAT vs. standard 12-month dual antiplatelet therapy (DAPT) in patients with ACS undergoing percutaneous coronary intervention (PCI) were selected. The primary efficacy endpoint was major adverse cardiovascular events (MACE) as defined in each trial and the primary safety endpoint was minor or major bleeding. Twenty-six RCTs testing seven different BRATs were included. The only strategy associated with a trade-off in MACE was 'upfront unguided de-escalation' in the subgroup of non-EAs (risk ratio 1.16, 95% confidence interval 1.09-1.24). All but aspirin monotherapy-based strategies (i.e. 'short and very short DAPT followed by aspirin') were associated with reduced bleeding compared with standard DAPT in both EA and non-EA patients. There were no significant differences between subgroups, but the lack of RCTs in some of the included strategies and the difference in the certainty of evidence between EA and non-EA patients revealed that the evidence in support of different BRATs in ACS undergoing PCI is influenced by ethnicity. Moreover, absolute risk reduction estimation revealed that some BRATs might be more effective than others in reducing bleeding according to ethnicity. CONCLUSION The majority of BRATs are associated with reduced bleeding without any trade-off in hard ischaemic endpoints regardless of ethnicity. However, the supporting evidence and relative safety profiles of different BRATs might be significantly affected by ethnicity, which should be taken into account in clinical practice.

De-escalation of Antiplatelet Therapy After Percutaneous Coronary Intervention in East Asian Patients With Acute Coronary Syndrome. Clin Ther 2024; 46:114-121. [PMID: 38071131 DOI: 10.1016/j.clinthera.2023.08.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2022] [Revised: 04/26/2023] [Accepted: 08/04/2023] [Indexed: 02/27/2024]
Abstract
PURPOSE East Asian individuals have a lower risk of thromboembolic events while potentially carrying a higher risk of bleeding events compared with non-Asian individuals. The aim of the present analysis was to investigate the effectiveness and safety of the de-escalation of antiplatelet therapy compared with standard dual antiplatelet therapy (DAPT) in East Asian patients undergoing percutaneous coronary intervention (PCI). METHODS Randomized controlled trials comparing de-escalation with DAPT in patients with acute coronary syndrome (ACS) were retrieved from electronic databases from their inception until March 2022. Outcomes included major adverse cardiovascular events (MACE), ischemic events, major bleeding, minor bleeding, and any bleeding. Subgroup analyses based on treatment strategy were conducted. Statistical analysis was performed by using Review Manager version 5.4. FINDINGS Eight randomized controlled trials from 539 potentially relevant publications with a total of 15,744 East Asian patients were included. Pooled data from these studies found a significantly lower MACE (0.82; 95% CI, 0.69-0.98) and major bleeding event (0.62; 95% CI, 0.46-0.82) in de-escalation than standard-DAPT without heterogeneity. Subgroup analysis was divided into DAPT followed by P2Y12 inhibitor monotherapy and a reducing dose of P2Y12 inhibitors. DAPT followed by P2Y12 inhibitor monotherapy had a 48% lower incidence of major bleeding events than standard DAPT (0.52; 95% CI, 0.27-1.00); there was no significant difference in major bleeding (0.99; 95% CI, 0.55-1.76) between the reducing dose of P2Y12 inhibitors and standard DAPT. IMPLICATIONS De-escalation is a promising and potentially optimal antiplatelet therapy for patients from East Asia with PCI. DAPT followed by P2Y12 inhibitor monotherapy might be a safer and equally effective approach compared with standard DAPT in East Asian patients with PCI. PROSPERO identifier: CRD42022319983.

Abstract
The new guidelines of the European Society of Cardiology (ESC) on the management of acute coronary syndrome (ACS) in 2023 encompass updates for both the guidelines pertaining to ST elevation myocardial infarction (STEMI) and acute coronary syndrome without ST segment elevation (NSTE-ACS). The previously separated guidelines from 2017 and 2020 were therefore revised and summarized. These guidelines address various topics, including diagnostics, acute management, antithrombotic treatment, out-of-hospital cardiac arrest, cardiogenic shock, invasive strategies, and long-term treatment. The notable updates compared to earlier guidelines address the recommendation regarding the timing of invasive diagnostics in NSTE-ACS (Non-ST elevation acute coronary syndrome), the procedure of revascularization in multivessel coronary artery disease and alternative regimens for antithrombotic treatment in patients with a high risk of bleeding.

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.

Optimal anti-platelet therapy for older patients with acute coronary syndrome: a network meta-analysis of randomized trials comprising 59,284 older patients. J Thromb Thrombolysis 2024; 57:143-154. [PMID: 37548902 PMCID: PMC10830599 DOI: 10.1007/s11239-023-02875-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 07/20/2023] [Indexed: 08/08/2023]
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
BACKGROUND Contemporary dual antiplatelet therapy (DAPT) strategies, such as short-term DAPT or de-escalation of DAPT, have emerged as attractive strategies to treat patients with acute coronary syndrome (ACS). However, it remains uncertain whether they are suitable for elderly patients. METHODS PubMed, Embase, and Cochrane CENTRAL databases were searched in September 2022. Randomized controlled trials (RCTs) investigating DAPT strategies, including standard (12 months), short-term, uniform de-escalation, and guided-selection strategies for elderly patients with ACS (age ≥ 65 years) were identified, and a network meta-analysis was conducted. The primary endpoint was the net clinical benefit outcome, a composite of major adverse cardiovascular events (MACEs: cardiovascular death, myocardial infarction, or stroke) and clinically relevant bleeding (equivalent to bleeding of at least type 2 according to the Bleeding Academic Research Consortium). The secondary outcomes were MACE and major bleeding. RESULTS Sixteen RCTs with a combined total of 47,911 patients were included. The uniform de-escalation strategy was associated with an improved net clinical benefit compared with DAPT using potent P2Y12 inhibitors. The short-term DAPT strategy was associated with reduced risks of the primary outcome and major bleeding compared with DAPT using potent P2Y12 inhibitors, however, it was ranked as the least effective strategy for MACE compared with other DAPT strategies. CONCLUSIONS Uniform de-escalation and short-term DAPT strategies may be advantageous for elderly patients, but need to be tailored based on individual bleeding and ischemic risks. Further RCTs of contemporary DAPT strategies specifically designed for elderly patients are warranted to confirm the findings of the present study.

Abstract
PURPOSE OF REVIEW Review the clinical outcomes of different antithrombotic strategies in patients with high bleeding risk (HBR) after percutaneous coronary intervention (PCI). RECENT FINDINGS Patients with HBR after PCI include those with advanced age (e.g. >75 years of age), a prior history of major bleeding, anemia, chronic kidney disease, and those with indications for long-term anticoagulation. Strategies that successfully decrease bleeding risk in this population include shorter durations of dual antiplatelet therapy (DAPT; of 1-3 months) followed by single antiplatelet therapy with aspirin or a P2Y 12 inhibitor, or de-escalating from a more potent P2Y 12 inhibitor (prasugrel or ticagrelor) to less potent antiplatelet regimens (aspirin with clopidogrel or half-dose ticagrelor or half-dose prasugrel). Patients on DAPT, and a full dose anticoagulation for other indications, have a lower risk of major bleeding without an increase in 1-2-year adverse ischemic events, when rapidly switched from DAPT to a single antiplatelet therapy (within a week after PCI) with aspirin or clopidogrel. Longer term data on the benefits and risks of these strategies is lacking. SUMMARY In patients with HBR after PCI, shorter durations of DAPT (1-3 months) decrease the risk of major bleeding without increasing the risk of adverse ischemic events.

Abstract
BACKGROUND Various durations and de-escalation strategies of dual antiplatelet therapy (DAPT) after ST-elevation myocardial infarction (STEMI) or non-ST-elevation acute coronary syndromes (NSTE-ACS) have been tested in randomized controlled trials (RCT)s. However, evidence by specific ACS subtype is unknown. METHODS PubMed, EMBASE, and Cochrane CENTRAL were searched in February 2023. RCTs on DAPT strategies included STEMI or NSTE-ACS patients with standard DAPT (12 months) with clopidogrel or potent P2Y12 inhibitors, short-term DAPT (≤6 months) followed by potent P2Y12 inhibitors or aspirin, unguided de-escalation from potent P2Y12 inhibitors to low-dose potent P2Y12 inhibitors or clopidogrel at one month, and guided selection with genotype or platelet function tests were identified. The primary outcome was the net adverse clinical events (NACE) defined as a composite of major adverse cardiovascular events (MACE) and clinically relevant bleeding events. RESULTS Twenty RCTs with a combined total population of 24,745 STEMI and 37,891 NSTE-ACS patients were included. In STEMI patients, unguided de-escalation strategy was associated with a lower rate of NACE compared with standard DAPT using potent P2Y12 inhibitors (HR:0.57; 95% CI:0.34-0.96) without increased risk of MACE. In NSTE-ACS patients, unguided de-escalation strategy was associated with a lower rate of NACE compared with the guided selection strategy (HR:0.65; 95% CI:0.47-0.90), standard DAPT using potent P2Y12 inhibitors (HR:0.62; 95% CI:0.50-0.78) and standard DAPT using clopidogrel (HR:0.73; 95% CI:0.55-0.98) without increased risk of MACE. CONCLUSION Unguided de-escalation strategy was associated with a reduced risk of NACE and may be the most effective DAPT strategy for STEMI and NSTE-ACS.

Abstract
BACKGROUND Short-term (≤6 months) dual antiplatelet therapy (DAPT) and DAPT de-escalation become attractive for patients with acute coronary syndrome. METHODS A systemic search identified randomized controlled trials that included patients with acute coronary syndrome treated using (1) standard DAPT (12 months) with clopidogrel, prasugrel (standard/low dose), or ticagrelor; (2) extended DAPT (≥18 months); (3) short-term DAPT (≤6 months) followed by P2Y12 inhibitor or aspirin; (4) 12-month DAPT with unguided de-escalation from potent P2Y12 inhibitors to low-dose potent P2Y12 inhibitor or clopidogrel at 1 month; and (5) guided selection DAPT with genotype or platelet function tests. The primary efficacy outcome (major adverse cardiovascular events) was a composite of cardiovascular death, myocardial infarction, or stroke. The primary safety outcome was major or minor bleeding. RESULTS This meta-analysis included 32 randomized controlled trials with 103 497 patients. While there were no differences in efficacy between short, unguided de-escalation and guided selection strategies, unguided de-escalation was associated with reduced risk of major adverse cardiovascular events compared with standard DAPT with clopidogrel or ticagrelor (hazard ratio [95% CI], 0.67 [0.49-0.93] and 0.68 [0.50-0.93]). Both short DAPT followed by P2Y12 inhibitor and unguided de-escalation were associated with reduced risks in safety compared with other strategies, including guided selection (hazard ratio [95% CI], 0.66 [0.47-0.93] and 0.48 [0.33-0.71]). Short DAPT followed by a P2Y12 inhibitor was associated with reduced risk of major bleeding and all-cause death compared with standard, extended DAPT (eg, versus DAPT with clopidogrel; hazard ratio [95% CI], 0.64 [0.42-0.97] and 0.60 [0.44-0.82]). By rankogram, unguided de-escalation strategy was the safest and most effective strategy in reducing major adverse cardiovascular events and major or minor bleeding while short DAPT followed by P2Y12 inhibitor was ranked the best for major bleeding and all-cause death. CONCLUSIONS In patients with acute coronary syndrome, unguided de-escalation was associated with the lowest risk of major adverse cardiovascular events and major or minor bleeding outcomes, while short DAPT followed by P2Y12 inhibitor was associated with the lowest risk of major bleeding and all-cause death.

Abstract
INTRODUCTION Dual antiplatelet therapy (DAPT), referred to as the combination of aspirin and P2Y12 receptor antagonist (clopidogrel or ticagrelor), potentially improves patency of saphenous vein grafts (SVG) after coronary artery bypass grafting (CABG), while it is further proposed that DAPT potentially increases bleeding risk. Compared with DAPT, de-escalated DAPT (De-DAPT) is an effective antiplatelet strategy for acute coronary syndrome treatment, which significantly reduces the risk of bleeding without increasing the incidence of major adverse cardiovascular events. However, insufficient evidence is available to determine the timing of DAPT after CABG. METHODS AND ANALYSIS ETHICS AND DISSEMINATION: The Ethics Committee in Fuwai hospital approved this study (2022-1774). Fifteen centres agreed to participate the TOP-CABG trial, and the study has been approved in these 15 centres by whose ethics committee. The results of the trial will be submitted for publication in a peer-reviewed journal. TRIAL REGISTRATION NUMBER NCT05380063.

Abstract
The thrombosis-related diseases are one of the leading causes of illness and death in the general population, and despite significant improvements in long-term survival due to remarkable advances in pharmacologic therapy, they continue to pose a tremendous burden on healthcare systems. The oxidative stress plays a role of pivotal importance in thrombosis pathophysiology. The anticoagulant and antiplatelet drugs commonly used in the management of thrombosis-related diseases show several pleiotropic effects, beyond the antithrombotic effects. The present review aims to describe the current evidence about the antioxidant effects of the oral antithrombotic therapies in patients with atherosclerotic disease and atrial fibrillation.

Abstract
Background Metabolic abnormalities are associated with the occurrence, severity, and poor prognosis of coronary artery disease (CAD), some of which affect the antiplatelet efficacy of clopidogrel. Free fatty acids (FFAs) is a biomarker for metabolic abnormalities, and elevated FFAs is observed among CAD patients. Whether FFAs enhances residual platelet reactivity induced by adenosine diphosphate (ADP) while using clopidogrel was unknown. The purpose of our study is exploring the issue. Method Current study included 1,277 CAD patients using clopidogrel and used logistic regression to detect whether the higher level of FFAs is associated with high residual platelet reactivity (HRPR). We additionally performed subgroup and sensitivity analyses to evaluate the stability of the results. We defined HRPR as ADP-induced platelet inhibition rate (ADPi) < 50% plus ADP-induced maximum amplitude (MAADP) > 47 mm. Results 486 patients (38.1%) showed HRPR. The proportion of HRPR among patients with higher FFAs (>0.445 mmol/L) is greater than among patients with lower FFAs (46.4% vs. 32.6%, P < 0.001). Multivariate logistic regression demonstrated that higher FFAs (>0.445 mmol/L) is independently associated with HRPR (adjusted OR = 1.745, 95% CI, 1.352-2.254). After subgroup and sensitivity analyses, the results remained robust. Conclusion The higher level of FFAs enhances residual platelet reactivity induced by ADP and is independently associated with clopidogrel HRPR.

Abstract
Background Bleeding events are frequently applied as safety end points for randomized controlled trials (RCTs) investigating the effect of antithrombotic agents in patients with coronary artery disease. However, whether a bleeding event is a valid surrogate for death remain uncertain. Objectives This study aimed to assess the correlation between the treatment effect on bleeding events and mortality. Methods Multiple databases were searched to identify RCTs studying antithrombotic agents for patients with coronary artery disease through August 2022. Major and minor bleeding events were defined in included trials, mostly defined with BARC (Bleeding Academic Research Consortium) or TIMI (Thrombolysis In Myocardial Infarction) criteria. Trial-level correlations between nonfatal bleeding events and mortality were assessed. We performed subgroup analyses by the definitions of bleeding (BARC vs TIMI criteria), study year, and follow-up duration. We used a cutoff with a lower limit of 95% confidence interval of R2 >0.72 as a strong correlation and with an upper limit of 95% confidence interval of R2 <0.50 as a weak correlation. Results A total of 48 RCTs with 181,951 participants were analyzed. Overall, trial-level R2 for major and minor bleeding were 0.09 (95% CI: 0.00-0.26) and 0.09 (95% CI: 0.00-0.27) for all-cause or cardiovascular death, respectively. When confined to major bleeding, R2 were 0.03 (95% CI: 0.00-0.13) and 0.01 (95% CI: 0.00-0.05), respectively. All of the subgroup analyses did not show any significant correlations. Conclusions We demonstrated a trial-defined bleeding event may not be a valid surrogate for mortality in RCTs investigating the effect of antithrombotic agents for coronary artery disease.

Abstract
PURPOSE Asians often face the problems of clopidogrel resistance and East Asian paradox. This study aimed to evaluate the effects of P2Y12 inhibitors, including low-dose prasugrel 2.5 mg, on the P2Y12 reaction unit (PRU) in the chronic phase after percutaneous coronary intervention (PCI). METHODS A total of 348 patients were studied. PRU was measured 6-12 months after PCI and subsequently, 6 months later using a P2Y12 assay, respectively. This study evaluated the proportion of bleeding risk (PRU ≤ 85) and ischemic risk (PRU ≥ 239) as primary endpoints, and the prediction of bleeding risk and ischemic risk using multivariable logistic regression analysis. RESULTS At baseline, 136 patients (39%) received prasugrel 3.75 mg, 48 patients (14%) received prasugrel 2.5 mg, and 164 patients (47%) received clopidogrel 75 mg. Clopidogrel 75 mg had a significantly higher proportion of ischemic risk within one year after PCI than the other groups, and was an independent predictor for ischemic risk with reference of prasugrel 3.75 mg. In addition, switching from clopidogrel 75 mg to prasugrel 2.5 mg significantly lowered and aggregated the PRU value. Whereas, dose reduction of prasugrel had a significantly lower proportion of bleeding risk over one year after PCI than the continuation of prasugrel 3.75 mg, and was an independent predictor for bleeding risk with reference of continuation of prasugrel 3.75 mg. CONCLUSIONS Prasugrel 2.5 mg has a lower ischemic risk and a more stable PRU value compared with clopidogrel treatment. Prasugrel also contributes to a decline in bleeding risk with concomitant dose reduction.

Abstract
BACKGROUND Guideline-recommended dual antiplatelet therapy (DAPT; aspirin plus prasugrel/ticagrelor) for 12 months in acute coronary syndrome (ACS) patients increases bleeding, with East Asians (EAs) exhibiting higher bleeding and lower ischemic risk, compared with non-East Asians (nEAs). We sought to compare DAPT "de-escalation" strategies in EA and nEA populations. METHODS A systematic review and meta-analysis of randomized controlled trials assessing reduction of DAPT intensity or duration in ACS patients undergoing percutaneous coronary intervention, in EA and nEA, was performed using a random-effects model. RESULTS Twenty-three trials assessed reduction of DAPT intensity (n = 12) or duration (n = 11). Overall, reduced DAPT intensity attenuated major bleeding (odds ratio [OR]: 0.78, 95% confidence interval [CI]: 0.65-0.94, p = 0.009), without impacting net adverse cardiovascular events (NACE) or major adverse cardiovascular events (MACE). In nEA, this increased MACE (OR: 1.20, 95% CI: 1.09-1.31, p < 0.0001) without impacting NACE or bleeding; while in EA, it reduced major bleeding (OR: 0.71, 95% CI: 0.53-0.95, p = 0.02) without affecting NACE or MACE. Overall, abbreviation of DAPT duration reduced NACE (OR: 0.90, 95% CI: 0.82-0.99, p = 0.03) due to major bleeding (OR: 0.69, 95% CI: 0.53-0.99, p = 0.006), without impacting MACE. In nEA, this strategy did not impact NACE, MACE, or major bleeding; while in EA, it reduced major bleeding (OR: 0.60, 95% CI: 0.4-0.91, p = 0.02) without impacting NACE or MACE. CONCLUSION In EA, reduction of DAPT intensity or duration can minimize bleeding, without safety concerns. In nEA, reduction of DAPT intensity may incur an ischemic penalty, while DAPT abbreviation has no overall benefit.

Abstract
Dual antiplatelet therapy with aspirin and the oral P2Y12 inhibitor clopidogrel as the cornerstone of treatment for patients with an acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI) was firstly established in 2001. Soon thereafter, the newer-generation P2Y12 inhibitors prasugrel and ticagrelor became commercially available. The clinical management of ACS patients undergoing PCI has evolved significantly in the last 2 decades, with a shift toward more rapid invasive management, broader use of drug-eluting stents, and the increasing recognition that major bleeding due to antiplatelet therapy is detrimental. In this ever-changing scenario, numerous studies have addressed 4 main questions regarding P2Y12 inhibition in ACS patients undergoing PCI: timing, selection, modulation, and duration. This paper reviews the latest evidence surrounding these topical questions, with a focus on efficacy and safety data, practice guidelines, and residual areas of uncertainty.

Abstract
BACKGROUND Antiplatelet therapy deescalation has been suggested as an alternative to standard treatment with potent dual antiplatelet therapy (DAPT) for 1 year in low bleeding risk patients with acute coronary syndromes undergoing percutaneous coronary intervention to mitigate the increased risk of bleeding. Whether this strategy preserves the ischemic and survival benefits of potent DAPT is uncertain. METHODS We performed a pairwise meta-analysis in patients with acute coronary syndrome undergoing percutaneous coronary intervention treated with either 1-year standard potent DAPT versus deescalation therapy (potent DAPT for 1-3 months followed by either reduced potency DAPT or ticagrelor monotherapy for up to 1 year). Randomized trials comparing standard DAPT versus deescalation therapy in patients with acute coronary syndrome undergoing percutaneous coronary intervention were searched through MEDLINE, EMBASE, Cochrane databases, and proceedings of international meetings. The primary end point was 1-year all-cause mortality. RESULTS The meta-analysis included 6 trials in which 20 837 patients were randomized to potent DAPT for 1 to 3 months followed by deescalation therapy for up to 1 year (n=10 392) or standard potent DAPT for 1 year (n=10 445). Deescalation therapy was associated with lower 1-year rates of all-cause mortality compared with standard therapy (odds ratio, 0.75 [95% CI, 0.59-0.95]; P=0.02). Deescalation therapy was also associated with lower rates of major bleeding (odds ratio, 0.59 [95% CI, 0.48-0.72]; P<0.0001), with no significant difference in major adverse cardiac events (major adverse cardiovascular events; odds ratio, 0.89 [95% CI, 0.77-1.04]; P=0.14). CONCLUSIONS In low bleeding risk patients with acute coronary syndrome undergoing percutaneous coronary intervention, compared with 1-year of potent DAPT, antiplatelet therapy deescalation therapy after 1 to 3 months was associated with decreased mortality and major bleeding with similar rates of major adverse cardiovascular events.

Abstract
Background Inflammation increases the risk of thrombosis in coronary artery disease (CAD) patients and affects the antiplatelet efficacy of clopidogrel. C1q interacts with platelets to activate platelets and induce thrombosis by participating in and regulating the inflammatory response. Whether C1q affects adenosine diphosphate (ADP)-induced platelet reactivity during clopidogrel therapy was unclear and our study aimed to explore the issue. Method We enrolled 1,334 CAD patients receiving clopidogrel therapy and evaluated the association between C1q level and high residual platelet reactivity (HRPR) using logistic regression and restricted cubic spline (RCS). HRPR was defined as ADP-induced maximum amplitude (MAADP) > 47 mm plus ADP-induced platelet aggregation (ADPi) < 50%. Results A total of 516 patients (38.7%) performed HRPR. The frequency of HRPR increases with the increase in C1q level (26.3%, 38.4%, 43.2%, and 46.7% for the 1st to 4th quartile of C1q). The result of multivariate logistic regression demonstrated elevated C1q as an independent predictor for HRPR (2nd quartile: OR = 1.722, 95% CI 1.215–2.440; 3rd quartile: OR = 2.015, 95% CI 1.413–2.874; 4th quartile: OR = 2.362, 95% CI 1.631–3.421, compared to the 1st quartile). RCS depicted the nonlinear relationship between C1q and HRPR risk (p for non-linear < 0.05). Conclusion The current research is the first to explore the association of C1q and ADP-induced platelet reactivity and to demonstrate elevated C1q as an independent risk factor for HRPR in CAD patients during clopidogrel therapy.

Abstract
Acute myocardial infarction (AMI) is still a huge danger to human health. Sensitive markers are necessary for the prediction of the risk of AMI and would be beneficial for managing the incidence rate. N6-methyladenosine (m6A) RNA methylation regulators have been confirmed to be involved in the development of various diseases. However, their function in AMI has not been fully elucidated. The purpose of this study was to determine the expression of m6A RNA methylation regulators in AMI as well as their possible functions and prognostic values. The GEO database was used to get the gene expression profiles of patients with and without AMI, and bioinformatics assays of genes with differently expressed expression were performed. We establish two separate m6A subtypes, and relationships between subtypes and immunity were studied. In this study, we identified IGF2BP1, FTO, RBM15, METTL3, YTHDC2, FMR1, and HNRNPA2B1 as the seven major m6A regulators. A nomogram model was developed and confirmed. The consensus clustering algorithm was conducted to categorize AMI patients into two m6A subtypes from the identified m6A regulators. Patients who have activated T-cell activities were found to be in clusterA; they may have a better prognosis as a result. Importantly, we found that patients with high METTL3 expressions had an increased level of Activated.CD4.T.cell and Type.2.T.helper.cell, while having a decreased level of CD56bright.natural.killer.cell, Macrophage, Monocyte, Natural.killer.cell, and Type.17.T.helper.cell. Overall, a diagnostic model of AMI was established based on the genes of IGF2BP1, FTO, RBM15, METTL3, YTHDC2, FMR1, and HNRNPA2B1. Our investigation of m6A subtypes may prove useful in the developments of therapy approaches for AMI.

Abstract
BACKGROUND The benefit of dual antiplatelet therapy (DAPT) for reducing ischemic events is greatest in the early period of acute coronary syndrome, and recent randomized controlled trials have investigated the unguided de-escalation strategy of changing potent P2Y12 inhibitors to less potent or reduced-dose P2Y12 inhibitors 1 month after acute coronary syndrome. However, it remains unclear which strategy is more effective and safer: the uniform unguided de-escalation strategy versus the personalized guided selection of DAPT with genotype or platelet function tests. METHODS PubMed, EMBASE, and Cochrane Central were searched for articles published from database inception to September 10, 2021. Randomized controlled trials investigating DAPT using clopidogrel, low-dose prasugrel, standard-dose prasugrel, ticagrelor, unguided de-escalation strategy, and guided selection strategy for patients with acute coronary syndrome were included. Hazard ratios and relative risk estimates were extracted from each study. The estimates were pooled using a random-effects network meta-analysis. The primary efficacy outcome was major adverse cardiovascular events, defined as a composite of cardiovascular death, myocardial infarction, or stroke. The primary safety outcome was major or minor bleeding. Secondary outcomes were all-cause death, cardiovascular death, myocardial infarction, stroke, stent thrombosis, and major bleeding. RESULTS This study included 19 randomized controlled trials with 69 746 patients. Compared with guided selection of DAPT, unguided de-escalation of DAPT was associated with a decreased risk of the primary safety outcome (hazard ratio, 0.48 [95% CI, 0.33-0.72]) without increased risks of major adverse cardiovascular events (hazard ratio, 0.82 [95% CI, 0.53-1.28]) or any secondary outcomes. The results were similar when the guided selection strategy was divided into platelet function-guided and genotype-guided strategies. CONCLUSIONS Compared with guided selection of DAPT, unguided de-escalation of DAPT decreased bleeding without increasing ischemic events in patients after acute coronary syndrome. If a strategy of de-escalation is chosen, these findings do not support the routine use of personalized guiding tests.

Abstract
OBJECTIVES To investigate outcome with selective, clopidogrel-based therapies vs conventional treatment in patients undergoing percutaneous coronary intervention (PCI), especially for acute coronary syndrome. BACKGROUND Safety and efficacy of alternative, selective, clopidogrel-based therapies after PCI are not robustly established. METHODS We performed a study-level meta-analysis on six randomized trials investigating selective clopidogrel-based therapies (three on unguided de-escalation, N=3,473; three on guided clopidogrel therapy, N=7,533). Control groups received ticagrelor or prasugrel treatment. Main endpoints were major bleeding, any bleeding, major adverse cardiovascular events (MACE) and net clinical endpoint. RESULTS The incidence of major bleeding and MACE was similar in the selective, clopidogrel-based therapy vs conventional treatment arm (OR 0·72, 95% CI 0·51-1·01, p=0·06; OR 0·93, 0·72-1·20, p=0·58; respectively). The rates of any bleeding were lower in the selective, clopidogrel-based therapy vs conventional treatment group (OR 0·57, 0·40-0·80, p=0·001); this greater safety was significant for unguided de-escalation (OR 0·43, 0·32-0·58, p=0·00001) and non-significant for guided clopidogrel therapy (OR 0·72, 0·51-1·02, p=0·07; p for interaction 0·03). The incidence of the net clinical endpoint was fewer in the selective, clopidogrel-based therapy vs conventional treatment arm (OR 0·59, 0·41-0·85, p=0·004); this benefit was significant for unguided de-escalation (OR 0·50, 0·39-0·64, p<0·00001) and non-significant for guided clopidogrel therapy (OR 0·85, 0·62-1·16, p=0·30; p for interaction 0·01). CONCLUSIONS As compared with prasugrel/ticagrelor treatment, alternative, selective, clopidogrel-based approaches provide a similar protection from cardiovascular events, reduce the risk of any bleeding and are associated with a greater net benefit. These beneficial effects were prevalent with unguided de-escalation to clopidogrel.

Abstract
Platelets are at the forefront of human health and disease following the advances in their research presented in past decades. Platelet activation, their most crucial function, although beneficial in the case of vascular injury, may represent the initial step for thrombotic complications characterizing various pathologic states, primarily atherosclerotic cardiovascular diseases. In this review, we initially summarize the structural and functional characteristics of platelets. Next, we focus on the process of platelet activation and its associated factors, indicating the potential molecular mechanisms involving inflammation, endothelial dysfunction, and miRs. Finally, an overview of the available antiplatelet agents is being portrayed, together with agents possessing off-set platelet-inhibitory actions, while an extensive presentation of drugs under investigation is being given.

Short Duration of DAPT Versus De-Escalation After Percutaneous Coronary Intervention for Acute Coronary Syndromes. JACC Cardiovasc Interv 2022; 15:268-277. [PMID: 35144783 DOI: 10.1016/j.jcin.2021.11.028] [Citation(s) in RCA: 60] [Impact Index Per Article: 30.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/03/2021] [Revised: 11/24/2021] [Accepted: 11/24/2021] [Indexed: 12/27/2022]
Abstract
OBJECTIVES The aim of this study was to compare short dual antiplatelet therapy (DAPT) and de-escalation in a network meta-analysis using standard DAPT as common comparator. BACKGROUND In patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI), shortening DAPT and de-escalating to a lower potency regimen mitigate bleeding risk. These strategies have never been randomly compared. METHODS Randomized trials of DAPT modulation strategies in patients with ACS undergoing PCI were identified. All-cause death was the primary outcome. Secondary outcomes included net adverse cardiovascular events (NACE), major adverse cardiovascular events, and their components. Frequentist and Bayesian network meta-analyses were conducted. Treatments were ranked on the basis of posterior probability. Sensitivity analyses were performed to explore sources of heterogeneity. RESULTS Twenty-nine studies encompassing 50,602 patients were included. The transitivity assumption was fulfilled. In the frequentist indirect comparison, the risk ratio (RR) for all-cause death was 0.98 (95% CI: 0.68-1.43). De-escalation reduced the risk for NACE (RR: 0.87; 95% CI: 0.70-0.94) and increased major bleeding (RR: 1.54; 95% CI: 1.07-2.21). These results were consistent in the Bayesian meta-analysis. De-escalation displayed a >95% probability to rank first for NACE, myocardial infarction, stroke, stent thrombosis, and minor bleeding, while short DAPT ranked first for major bleeding. These findings were consistent in node-split and multiple sensitivity analyses. CONCLUSIONS In patients with ACS undergoing PCI, there was no difference in all-cause death between short DAPT and de-escalation. De-escalation reduced the risk for NACE, while short DAPT decreased major bleeding. These data characterize 2 contemporary strategies to personalize DAPT on the basis of treatment objectives and risk profile.

Abstract
AIM Optimal dual antiplatelet therapy (DAPT) in patients undergoing percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS) intends to balance ischemic and bleeding risks. Various DAPT de-escalation strategies, defined as switching from a full-dose potent to a reduced dose or less potent P2Y12 inhibitor, have been evaluated in several ACS-PCI trials. We aimed to compare DAPT de-escalation to standard DAPT with full dose potent P2Y12 inhibitors in ACS patients who underwent PCI. METHODS & RESULTS PubMed, Google Scholar and Cochrane Central Register of Controlled Trials were searched for eligible randomised controlled trials. Aspirin monotherapy trials were excluded. Five randomised trials (n = 10,779 patients) that assigned DAPT de-escalation (genetically guided to clopidogrel n = 1,242; platelet function guided to clopidogrel n = 1,304; unguided to clopidogrel n = 1,672; unguided to lower dose n = 1,170) versus standard DAPT (control group n = 5,391) were included in this analysis. DAPT de-escalation was associated with a significant reduction in Bleeding Academic Research Consortium ≥ 2 bleeding (HR 0.57, 95% CI 0.42-0.78; I2 = 77%) as well as major adverse cardiac events, represented in most trials by the composite of cardiovascular mortality, myocardial infarction, stent thrombosis and stroke (HR 0.77, 95% CI 0.62-0.96; I2 = 0%). Notwithstanding the limited power, consistency was noted across various de-escalation strategies. CONCLUSION De-escalation of DAPT after PCI for ACS, both unguided and guided by genetic or platelet function testing, was associated with lower rates of clinically relevant bleeding and ischemic events as compared to standard DAPT with potent P2Y12 inhibitors based on five open-label RCTs reviewed.
