Abstract
The older population represents a unique subset of patients due to a higher rate of comorbidities and risk factors, which can lead to a higher rate of ischemic and bleeding events. As a result, older adults are mainly underrepresented or excluded from randomized trials. Although the advancement in the percutaneous coronary intervention field with the development of new technologies, techniques, and potent antiplatelet therapy led to a reduction of ischemic risk, there is still a concern regarding bleeding hazards. Apart from the global utilization of less invasive trans-radial approach and proton pump inhibitors to reduce bleeding risk, proper tailoring of antiplatelet therapy in the older person is imperative. So far, several antiplatelet drugs have been introduced in different clinical scenarios, with dual antiplatelet therapy (combination of acetylsalicylic acid and P2Y12 inhibitor) recommended after percutaneous coronary intervention. The decision on the choice of antiplatelet drug and the DAPT duration is challenging and should be based on the relationship between ischemia and bleeding with the purpose of reducing ischemic events but not at the expense of increased bleeding complications. This is particularly important in the older population, where the evidence is obscure. The main objective of this review is to summarize the available evidence on contemporary antiplatelet therapy and different approaches of de-escalation strategies in older patients after percutaneous coronary intervention.

[PMID: 37511955 PMCID: PMC10381391 DOI: 10.3390/life13071580] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2023] [Revised: 07/05/2023] [Accepted: 07/12/2023] [Indexed: 07/30/2023] Open
Abstract
Dual antiplatelet therapy (DAPT) combines two antiplatelet agents to decrease the risk of thrombotic complications associated with atherosclerotic cardiovascular diseases. Emerging data about the duration of DAPT is being published continuously. New approaches are trying to balance the time, benefits, and risks for patients taking DAPT for established cardiovascular diseases. Short-term dual DAPT of 3-6 months, or even 1 month in high-bleeding risk patients, is equivalent in terms of efficacy and effectiveness compared to long-term DAPT for patients who experienced percutaneous coronary intervention in an acute coronary syndrome setting. Prolonged DAPT beyond 12 months reduces stent thrombosis, major adverse cardiovascular events, and myocardial infarction rates but increases bleeding risk. Extended DAPT does not significantly benefit stable coronary artery disease patients in reducing stroke, myocardial infarction, or cardiovascular death. Ticagrelor and aspirin reduce cardiovascular events in stable coronary artery disease with diabetes but carry a higher bleeding risk. Antiplatelet therapy duration in atrial fibrillation patients after percutaneous coronary intervention depends on individual characteristics and bleeding risk. Antiplatelet therapy is crucial for post-coronary artery bypass graft and transcatheter aortic valve implantation; Aspirin (ASA) monotherapy is preferred. Antiplatelet therapy duration in peripheral artery disease depends on the scenario. Adding vorapaxar and cilostazol may benefit secondary prevention and claudication, respectively. Carotid artery disease patients with transient ischemic attack or stroke benefit from antiplatelet therapy and combining ASA and clopidogrel is more effective than ASA alone. The optimal duration of DAPT after carotid artery stenting is uncertain. Resistance to ASA and clopidogrel poses an incremental risk of deleterious cardiovascular events and stroke. The selection and duration of antiplatelet therapy in patients with cardiovascular disease requires careful consideration of both efficacy and safety outcomes. The use of combination therapies may provide added benefits but should be weighed against the risk of bleeding. Further research and clinical trials are needed to optimize antiplatelet treatment in different patient populations and clinical scenarios.

Extended, standard, or De-escalation antiplatelet therapy for patients with coronary artery disease undergoing percutaneous coronary intervention? A trial-sequential, bivariate, influential, and network meta-analysis. EUROPEAN HEART JOURNAL. CARDIOVASCULAR PHARMACOTHERAPY 2022; 8:717-727. [PMID: 35325105 DOI: 10.1093/ehjcvp/pvac020] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/03/2022] [Revised: 03/02/2022] [Accepted: 03/16/2022] [Indexed: 06/14/2023]
Abstract
AIMS The relative safety and efficacy of de-escalation, extended duration (ED) (>12-months), and standard dual antiplatelet therapy for 12-months (DAPT-12) in patients with coronary artery disease (CAD) undergoing percutaneous coronary intervention (PCI) remains controversial. METHODS AND RESULTS Online databases were queried to identify relevant randomized control trials (RCTs). ED-DAPT, high-potency (HP) DAPT, shorter duration (SD) DAPT, and low-dose (LD) DAPT were compared with DAPT-12. A trial sequential, bivariate, influential, and frequentist network meta-analysis (NMA) was performed to determine the pooled estimates. A total of 30 RCTs comprising 81 208 (40 839 experimental, 40 369 control arm) patients with CAD were included in the quantitative analysis. On NMA, compared with DAPT-12, all types of de-escalation, HP-DAPT-12, and ED-DAPT strategies had a statistically non-significant difference in the incidence of MACE at a median follow-up of 1-year. Similarly, there was no significant difference in the incidence of stroke, stent thrombosis, target lesion revascularization (TLR), target vessel revascularization (TVR), and all-cause mortality between DAPT-12 and all other strategies. The network estimates showed a significantly lower incidence of major bleeding with DAPT for 3-months followed by P2Y12-inhibitor monotherapy (RR 0.62, 95% CI 0.45-0.84), while a higher risk of bleeding with HP-DAPT for 12 months (RR 1.55, 95% CI 1.16-2.06). The net clinical benefit and rankograms also favoured DAPT-3 (P2Y12) and discouraged the use of HP-DAPT-12 and ED-DAPT. A subgroup analysis of 19 RCTs restricted to patients who presented with acute coronary syndrome (ACS) mirrored the findings of pooled analysis. A sensitivity analysis revealed no influence of any individual study or individual strategy on net ischemic estimates. The trial sequential analysis (TSA) illustrated a consistently non-significant difference at the interim analysis of trials, reaching the futility area for MACE, while the cumulative Z-values line surpassed the monitoring boundary as well as the required information size for major bleeding favouring de-escalation strategy. CONCLUSION DAPT for three months followed by ticagrelor-only and use of aspirin + clopidogrel after a short period of high potency DAPT appears to be a safe strategy for treating post-PCI patients. However, given the methodological limitations and inclusion of a small number of trials in novel de-escalation strategies, these findings need validation by future large scale RCTs.

Abstract
INTRODUCTION The decision to shorten the duration of DAPT following PCI in patients with ACS remains controversial because of the concern for increased ischemic events. METHODS We performed a comprehensive literature search in seven databases to explore the efficacy of 1 to 3 months of DAPT in patients who underwent PCI for ACS. Randomized controlled trials that compared 1 to 3 months with 6 to 12 months of DAPT after PCI for ACS were identified. Integrated hazard ratio (HR) and 95% confidence interval (CI) were calculated by random effects model for each prespecified outcome of interest. Meta-regression analyses were performed to examine the association of outcomes with select patient characteristics. RESULTS A total of 9 randomized controlled trials consisting of 25,907 patients were included. There was no difference in the hazard of NACE (HR 0.92, 95% CI 0.79-1.07) and MACE (HR 0.96, 95% CI 0.78-1.17) between 1 and 3 months of DAPT and 6 to 12 months of DAPT. However, implementing 1 to 3 months of DAPT was associated with lower hazard of both any bleeding (HR 0.55, 95% CI 0.46-0.66) and major bleeding (HR 0.47, 95% CI 0.36-0.62). Meta-regression revealed a nonsignificant but increasing trend of both NACE and MACE with greater proportion of left main and left anterior descending coronary artery lesions and greater proportion of STEMI included in the trials. CONCLUSION Our findings suggest that 1 to 3 months of DAPT has similar efficacy for preventing ischemic events with reduced bleeding risk compared with 6 to 12 months of DAPT.

Abstract
BACKGROUND The optimal duration of dual antiplatelet therapy is a matter of ongoing research. Clinical studies are assessing the optimal duration with the most favourable risk to benefit ratio. The efficacy of P2Y12 receptor inhibitors comparable to aspirin in preventing recurrent ischaemic events in patients with coronary artery diseases. OBJECTIVES To investigate the outcomes of short-duration dual antiplatelet therapy after PCI with early discontinuation of aspirin while maintaining patients on P2Y12 inhibitor through systematic review and meta-analysis of available literature. METHODS We systematically searched PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), and ClinicalTrials.gov. We included randomized controlled studies that measured clinical outcomes of efficacy (mortality and ischaemic events) and safety (bleeding) of short and standard-duration dual antiplatelet therapy. The protocol of this study was registered in the international prospective register of systematic reviews PROSPERO registry (CRD42020171468). RESULTS Four randomized controlled trials were included; GLOBAL LEADERS, SMARTCHOICE, STOPDAPT-2, and TWILIGHT. The total number of patients was 29,089. The safety outcomes showed a significant reduction in major bleeding events with short-duration dual antiplatelet therapy; the risk ratio was 0.61 (95% CI 0.38-0.99; z=2,00, p=0.05). There was no difference between short and standard-duration dual antiplatelet therapy regarding efficacy outcomes (all- cause death, major adverse cardiovascular events, myocardial infarction, stroke, and stent thrombosis). CONCLUSION Short-duration dual antiplatelet therapy followed by P2Y12 inhibitor monotherapy after PCI is a feasible option and can be adopted, especially in patients with a high risk of bleeding.

Efficacy and Safety of Very Short-Term Dual Antiplatelet Therapy After Drug-Eluting Stents Implantation for Acute Coronary Syndrome: A Systematic Review and Meta-Analysis of Randomized Clinical Trials. Front Cardiovasc Med 2021; 8:660360. [PMID: 34557526 PMCID: PMC8452852 DOI: 10.3389/fcvm.2021.660360] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2021] [Accepted: 07/30/2021] [Indexed: 01/01/2023] Open
Abstract
Background and Objective: Dual antiplatelet therapy (DAPT) is the basis for preventing ischemic events after percutaneous coronary intervention (PCI), and DAPT for 12 months has been the standard strategy recommended by the guidelines. However, patients with acute coronary syndrome (ACS) have a higher risk of thrombosis, and the application of very short-term DAPT (1–3 months) in patients with ACS is consistently controversial. The purpose of this study is to explore the efficacy and safety of DAPT for 1–3 months in patients with ACS who were implanted with drug-eluting stents (DES). Methods: We conducted a systematic review and meta-analysis of randomized controlled trials that compared the very short-term (3 months or less) with long-term (12 months or more) DAPT in patients with ACS after PCI. The randomized controlled trials were included by searching PubMed, EMBASE, and Cochrane Library database. The relative risk (RR) and 95% CIs for endpoint events were calculated by the fixed effects model, and trial sequential analysis was applied to calculate the anticipated sample size and assess the results. Result: A total of eight randomized controlled trials with 16,492 patients who met the inclusion criteria were conducted. There were no significant statistic differences in myocardial infarction (RR 1.05, 0.82–1.35, P = 0.68), stents thrombosis (RR 1.32, 0.85–2.07, P = 0.22), all-cause death (RR 0.87, 0.66–1.13, P = 0.29), and target vessel revascularization (RR 0.93, 0.76–1.13, P = 0.47). However, there were significant differences in major bleeding (RR 0.60, 0.50–0.73, P < 0.00001) and the net adverse cardiac and cerebrovascular events (RR 0.84, 0.74–0.95, P = 0.007). Conclusions: The strategy of DAPT for 1–3 months not only has a significant effect in patients with ACS who were implanted with DES but also reduces the risk of major bleeding. The scheme of short-term DAPT followed by P2Y12 receptor inhibitor monotherapy is especially beneficial for patients with ACS. The results of this systematic review and meta-analysis are based on the application of new generation DES and new oral antiplatelet drugs in patients with ACS, which are difficult to use in the general population (Registered by PROSPERO, CRD 42020210520).

Abstract
Background and Objective: The optimum duration of dual antiplatelet therapy (DAPT) remains uncertain in patients with acute coronary syndrome treated with new generation stents. This meta-analysis was performed to investigate ischemia and bleeding outcomes with different DAPT strategies. Methods: PubMed, Embase, Cochrane and Web of science from inception to May 27, 2020, were systematically searched. Randomized controlled trials were included to compare short-term (6 months or less) with standard (12 months) DAPT in patients with acute coronary syndrome treated with new generation stents. The primary endpoints were myocardial infarction, definite or probable stent thrombosis and major bleeding. The secondary endpoints included all-cause death, cardiovascular death, stroke, target vessel revascularization and net adverse clinical events. Random effect model and fixed effect model were used to calculate the odds ratio (OR) and 95% confidence interval (CI) of each endpoint. Results: Four randomized controlled trials and seven subgroup analyses of larger randomized controlled trials, including a total of 21,344 patients with acute coronary syndrome, met our inclusion criteria. The shorter DAPT was associated with significantly lower major bleeding compared with the standard DAPT (OR 0.71, 95% CI 0.56–0.90, P = 0.005, I2 = 25%), while without increasing the risk of myocardial infarction (OR 1.18, 0.88–1.58, P = 0.28, I2 = 20%), definite or probable stent thrombosis (OR 1.60, 0.98–2.59, P = 0.06, I2 = 0%). No significantly difference was observed in the risk of all-cause death (OR 0.96, 0.72–1.27, P = 0.76, I2 = 2%), cardiovascular death (OR 0.91, 0.62–1.33, P = 0.62, I2 = 0%), stroke (OR 0.84, 0.54–1.30, P = 0.43, I2 = 0%), target vessel revascularization (OR 1.14, 0.84–1.55, P = 0.41, I2 = 8%), and net adverse clinical events (OR 0.93, 0.80–1.07, P = 0.3, I2 = 18%) between the two groups. Conclusions: In patients with acute coronary syndrome treated with new generation stents, the shorter DAPT leads to a marked reduction in the risk of major bleeding compared with the standard DAPT. This benefit is achieved without increasing the risk of mortality or ischemic outcomes. The study protocol was registered in PROSPERO (CRD42020189871).

Absence of coronary angioscopy-derived in-stent thrombi is associated with major bleeding events in acute myocardial infarction. Atherosclerosis 2021; 319:62-71. [PMID: 33486352 DOI: 10.1016/j.atherosclerosis.2021.01.010] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/16/2020] [Revised: 12/23/2020] [Accepted: 01/07/2021] [Indexed: 01/23/2023]
Abstract
BACKGROUND AND AIMS The optimal duration of dual antiplatelet therapy for acute myocardial infarction is controversial because the bleeding risk outweighs the thromboembolic risk. We hypothesized that an in-stent thrombus (IS-thrombus) detected by coronary angioscopy (CAS) after stent implantation would be associated with high bleeding risk. METHODS This study included 208 patients who underwent CAS at 2 weeks after stent implantation for an acute myocardial infarction. The study was approved by the ethics committee at the Nihon University Itabashi Hospital (reference number RK-200714-10). RESULTS In 84 patients, in whom no IS-thrombus was identified in the culprit vessel using CAS, the major bleeding event rate was significantly higher than that in patients with IS-thrombi (n = 124). However, no difference was detected in major adverse cardiovascular events (MACE; stroke, hospitalization for a non-fatal myocardial infarction/unstable angina, target lesion revascularization, and cardiovascular death). After adjustments by the propensity score based on patient characteristics, the absence of IS-thrombi remained an independent predictor of major bleeding events (hazard ratio 4.73, 95% confidence interval 2.04-11.00, p < 0.001). CONCLUSIONS The absence of CAS-detected IS-thrombi in the subacute phase was independently associated with future major bleeding events, but not with MACE. These findings may help optimize the duration of dual antiplatelet therapy.

Optimizing Monotherapy Selection, Aspirin Versus P2Y12 Inhibitors, Following Percutaneous Coronary Intervention. Am J Cardiol 2020; 135:154-165.

Abstract
Dual antiplatelet therapy (DAPT) reduces ischemic and thrombotic events after percutaneous coronary intervention (PCI). Initial reports of higher myocardial infarction and mortality rates prompted guideline committees to choose 12-month duration of DAPT after PCI. However, higher bleeding rates with DAPT remain a major concern. Since these guidelines were published, there have been improvements in stent design, deployment techniques, and antiplatelet therapies, which have reduced ischemic events. To address bleeding concerns, trials were performed to evaluate the effectiveness of short-duration DAPT. Two main strategies were employed: (1) aspirin monotherapy after a short-duration DAPT, and (2) P2Y12 inhibitor monotherapy after a short-duration DAPT. In this review, we outline all the major trials on short-duration DAPT that have examined the previously mentioned strategies and propose a new individualized treatment algorithm for which monotherapy to choose or remove after PCI. In conclusion, while removing the P2Y12 inhibitor after a short DAPT appears to be safe in the low-risk population, removing aspirin and continuing the P2Y12 inhibitor as monotherapy would be the preferred strategy in intermediate- to high-risk patients to mitigate the bleeding risk.

Abstract
Percutaneous coronary intervention has become a mainstay in the management of coronary artery disease. While initially advanced age was considered a relative contraindication to invasive management of coronary artery disease, current cardiovascular practice stands solidly on an early invasive approach for elderly patients, typically based on radial access and drug-eluting stent implantation. Since the advent of coronary stents, oral antiplatelet therapy has proved crucial to maximize the benefits and minimize the risks of stenting, and this holds even truer in older patients rather than in younger ones. Indeed, the elderly is typically at higher risk of thrombotic events as well as bleeding complications, and thus careful decision making must be exercised to prescribe the most appropriate antiplatelet regimen. We thus conducted an umbrella review with scoping purposes on oral antiplatelet therapy in elderly patients undergoing percutaneous coronary intervention, retrieving 8 pertinent systematic reviews. We found that, while several drugs are available, ranging from aspirin to cilostazol, clopidogrel, dipyridamole, prasugrel, ticagrelor, and ticlopidine, most commonly a dual antiplatelet therapy comprising aspirin and a P2Y12 inhibitor is recommended, with subtle adjustments for pretreatment, loading, dose, duration, escalation or de-escalation, with the potential adjunct in selected patients of novel oral anticoagulants. Indeed, a flexible and individualized approach to oral antiplatelet therapy in elderly patients undergoing percutaneous coronary intervention is paramount, factoring patient features (exploiting thrombotic, bleeding and frailty scores), triage (including when appropriate non-invasive assessment of anatomic and functional significance of coronary artery disease), angiographic and other invasive imaging features, interventional technique, stent choice, rehabilitation, and secondary prevention.

Abstract
PURPOSE OF REVIEW Perioperative management of antiplatelet agents (APAs) in the setting of noncardiac surgery is a controversial topic of balancing bleeding versus thrombotic risks. RECENT FINDINGS Recent data do not support a clear association between continuation or discontinuation of APAs and rates of ischemic events, bleeding complications, and mortality up to 6 months after surgery. Clinical factors, such as indication and urgency of the operation, time since stent placement, invasiveness of the procedure, preoperative cardiac optimization, underlying functional status, as well as perioperative control of supply-demand mismatch and bleeding may be more responsible for adverse outcome than antiplatelet management. SUMMARY Perioperative management of antiplatelet therapy (APT) should be individually tailored based on consensus among the anesthesiologist, cardiologist, surgeon, and patient to minimize both ischemic/thrombotic and bleeding risks. Where possible, surgery should be delayed for a minimum of 1 month but ideally for 3-6 months from the index cardiac event. If bleeding risk is acceptable, dual APT (DAPT) should be continued perioperatively; otherwise P2Y12 inhibitor therapy should be discontinued for the minimum amount of time possible and aspirin monotherapy continued. If bleeding risk is prohibitive, both aspirin and P2Y12 inhibitor therapy should be interrupted and bridging therapy may be considered in patients with high thrombotic risk.

Abstract
This study aimed to identify the correlation of contradiction between DAPT score and PRECISE-DAPT score with the severity of coronary lesion in acute coronary syndromes (ACS).In total, 458 patients with ACS after a percutaneous coronary intervention (PCI) who had tolerated 1-year uneventful dual antiplatelet therapy (DAPT) were enrolled and divided into groups based on the Gensini score, number of stenosed vessels, and left main (LM) disease. Both DAPT score and PRECISE-DAPT score were calculated and the proportion of patients receiving conflicting recommendations from each score was compared among the groups.DAPT score as well as the proportion of patients with DAPT score ≥2 were associated with the Gensini score and the number of stenosed vessels. Similarly, PRECISE-DAPT score as well as the proportion of patients with PRECISE-DAPT score ≥25 were associated with the Gensini score and the number of stenosed vessels. The proportion of patients with DAPT score ≥2 along with PRECISE-DAPT score ≥25 were associated with Gensini score, but they had no significant association with the number of stenosed vessels (P = .006 and P = .075, respectively). None of those aforementioned items were associated with LM disease.The inconsistencies of DAPT scores and PRECISE-DAPT scores are frequent and associated with the severity of coronary disease, represented by the Gensini score. Appropriate clinical decisions should be individualized.

Abstract
Percutaneous coronary intervention (PCI) has become a standard-of-care procedure in the setting of angina or acute coronary syndrome. Antithrombotic therapy is the cornerstone of pharmacological treatment aimed at preventing ischemic events following PCI. Dual antiplatelet therapy as the combination of aspirin and P2Y12 inhibitor has been proven to decrease stent-related thrombotic risks. However, the optimal duration of dual antiplatelet therapy, an appropriate P2Y12 inhibitor, and the choice of aspirin versus P2Y12 inhibitor as single antiplatelet therapy remain controversial. Furthermore, the combined use of oral anticoagulation in addition to antiplatelet therapy is a complex issue in clinical practice, such as in patients with atrial fibrillation. The key challenge concerning the optimal antithrombotic regimen is ensuring a balance between protection against thrombotic events and against excessive increases in bleeding risk. In this review article, we summarize the current evidence concerning antithrombotic therapy in patients with coronary artery disease undergoing PCI.

Abstract
BACKGROUND Patients who undergo percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS) are at increased risk for subsequent ischemic events. HYPOTHESIS Short-term dual antiplatelet therapy (DAPT) (≤6 months) is inferior to standard or long-term DAPT in patients who undergo PCI for ACS events. METHODS We conducted a systematic review and meta-analysis of randomized controlled trials that compared short-term (≤6 months) to long-term (≥12 months) DAPT after PCI for ACS. We searched MEDLINE, EMBASE, SCOPUS, and the Cochrane Central Register of Controlled Trials database. RESULTS Ten randomized controlled trials, including a total of 12 696 patients, met our inclusion criteria. For short-term DAPT, duration of therapy ranged from 3 to 6 months, while long-term DAPT ranged from 12 to 24 months. The majority of studies used clopidogrel and second-generation drug-eluting stents. No statistically significant difference was found between short-term and long-term DAPT with regard to myocardial infarction (odds ratio 1.21; 95% confidence interval 0.94-1.57; P = 0.14), stent thrombosis (odds ratio 1.54; 95% confidence interval 1.00-2.38; P = 0.052), or major bleeding events (odds ratio 0.74; 95% confidence interval 0.49-1.11; P = 0.14). There was no significant difference in all-cause mortality, cardiac death, or net adverse cardiac and cerebrovascular events. CONCLUSIONS Our meta-analysis demonstrated that short-term DAPT (<6 months) after PCI for ACS was not associated with increased risk of myocardial infarction or stent thrombosis when compared to long-term DAPT.
