RESUMEN
BACKGROUND: The ONCO DVT study revealed superiority of 12-month relative to 3-month edoxaban treatment for the thrombotic risk in cancer-associated isolated distal deep vein thrombosis (DVT). However, it is unknown whether the superiority could be common in different modified Ottawa score subgroups. METHODS: In this post-hoc subgroup analysis of the ONCO DVT study, we stratified 601 patients into the low (≤-1, N=126), intermediate (0, N=323), and high (≥1, N=152) modified Ottawa score subgroups, and compared clinical outcomes between the 12-month and 3-month edoxaban treatment groups. RESULTS: The cumulative incidence of symptomatic recurrent venous thromboembolism (VTE) or VTE-related death was not different between the 12-month and 3-month edoxaban treatment groups in the low score subgroup (0.0% vs. 2.2%), whereas it was lower in the 12-month than in the 3-month edoxaban treatment group in the intermediate (0.8% vs. 7.6%) and high (3.1% vs. 15.6%) score subgroups. There were no significant differences in the cumulative incidences of the major bleeding between the 12-month and 3-month edoxaban treatment groups in the low (10.1% vs. 7.6%), intermediate (8.8% vs. 5.0%), and high (13.9% vs. 12.6%) score subgroups. CONCLUSIONS: A 12-month compared to 3-month edoxaban treatment showed a lower risk of thrombotic events in patients with cancer-associated isolated distal DVT in the intermediate and high modified Ottawa score subgroups, but not in the low score subgroup, suggesting a limited benefit of extended anticoagulation therapy beyond 3 months in patients with low modified Ottawa score.
RESUMEN
Background: A comprehensive cardiac rehabilitation (CR) program is recommended for coronary artery disease (CAD). However, many facilities do not have established programs for dietary guidance and patient education, resulting in an exercise-based CR program and limited efficacy for secondary prevention. Methods and Results: A pilot study will be conducted to develop an online Japanese-style intensive cardiac rehabilitation (J-ICR) program for Japanese patients with CAD and will examine adherence, safety, and efficacy. Twenty-four patients diagnosed with stable CAD will be randomly assigned in a 1 : 1 ratio to either an early or late-phase group. The program will comprise the following four parts: exercise sessions; dietary education centered on "the Japan diet"; mindfulness; and group support, with a frequency of 3 h per session, once a week for 12 weeks (a total of 36 h). The primary endpoint will be program feasibility, determined by examining its adherence. Physical examination and function, stress-coping skills, risk of classic CAD (e.g., lipid profile, glucose tolerance, and blood pressure), and dietary changes will be assessed as secondary endpoints. Conclusions: The online J-ICR program is designed as a comprehensive CR program for Japanese patients with CAD. If this program shows high adherence and an improvement in CAD risk factors, its secondary prevention effect should be verified with appropriately powered randomized trials at multiple centers.
RESUMEN
PURPOSE: While nirmatrelvir/ritonavir (NMV-r) has been positioned as a first-line treatment for mild to moderate COVID-19, it has multiple and significant drug-drug interactions (DDIs). The use of NMV-r in Japan has been limited compared to the United States. This study aimed to describe the distribution of DDIs with NMV-r and their management in patients with COVID-19 under the control of a management system for the appropriate use of NMV-r. METHODS: A retrospective observational study was conducted at a Japanese university hospital. The management system included a flowchart for selecting antivirals and a list for reviewing DDI management, based on the National Institutes of Health guidelines and the guidance of the Japanese Society of Pharmaceutical Health Care and Sciences. Patients with mild to moderate COVID-19 and prescribed NMV-r or molnupiravir (MOV) were included. The primary outcome was DDI management practices, including the selected COVID-19 medications. The secondary outcome included the distribution of DDI classification and the 30-day all-cause mortality. RESULTS: This study included 241 patients (median age of 60 years, 112 [46.5%] females), of whom 126 and 115 received NMV-r and MOV, respectively. Of the 241 patients, 145 (60.2%) received concomitant medications that have DDIs with NMV-r. All 30 patients with severe renal impairment or insufficient details on concomitant medications received MOV. Forty-nine patients with concomitant medications required alternative COVID-19 therapy consideration due to DDIs, of whom 42 (85.7%) patients received MOV. Eighty-one patients had concomitant medications requiring temporary adjustment, of whom 44 (54.3%) patients received NMV-r, and 42 of these patients temporarily adjusted these concomitant medications. Five patients with concomitant medications that can continued by monitoring the effects/adverse effects, of whom 4 (80.0%) patients received NMV-r. Seventy-six patients without concomitant medications requiring DDI management, of whom 71 (93.4%) patients received NMV-r. The 30-day all-cause mortality for eligible patients was 0.9% [95% confidence interval, 0.1-3.1]. CONCLUSIONS: Most patients received appropriate antivirals according to the classification of DDIs, and most patients with concomitant medications requiring temporary adjustment received the recommended DDI management. Our management system is effective in promoting the use of NMV-r in the appropriate patients and managing problematic DDIs.
RESUMEN
BACKGROUND AND AIMS: Previous studies have not found a consistent association between circulating proprotein convertase subtilisin/kexin type 9 (PCSK9) levels and the risk of cardiovascular events partly due to measurement methods that cannot distinguish between uncleaved and furin-cleaved forms of PCSK9. METHODS: This is a prespecified sub-study of the REAL-CAD study which is a prospective, multicenter, randomized trial to compare high- versus low-dose statin in patients with stable coronary artery disease (CAD). The primary endpoint was major adverse cerebrovascular and cardiovascular events (MACCE) defined as a composite of cardiovascular death, nonfatal myocardial infarction, nonfatal ischemic stroke, or unstable angina requiring emergency hospitalization. In this case-cohort study, serum mature (uncleaved) and furin-cleaved PCSK9 levels obtained at 6 months after randomization were measured among 426 participants who developed MACCE (cases) and 1,478 randomly selected participants (sub-cohort). RESULTS: From 1,478 patients in sub-cohort, the Cox proportional hazards models with a pseudolikelihood method for case-cohort design revealed that the risk of the primary endpoint in patients with the highest quartile of mature PCSK9 levels was similar to that in the lowest quartile (hazard ration [HR] 0.809; 95% confidence intervals [CI], 0.541-1.209). Similarly, the HR for the highest to lowest quartiles of furin-cleaved PCSK9 was 0.948 [95% CI, 0.645-1.392] (P = 0.784). Compared to the lowest quartile, neither serum mature nor furin-cleaved PCSK9 levels predicted MACCE. CONCLUSIONS: In a large-scale secondary prevention cohort, serum mature and furin-cleaved PCSK9 levels did not provide useful information for predicting future cardiovascular events in statin-treated patients with stable CAD.
RESUMEN
In May 2022, Hyogo Medical University Hospital introduced protocol-based pharmacotherapy management(PBPM), which is jointly planned by doctors and pharmacists, for certain cancer drug therapies. Colorectal cancer patients who underwent outpatient cancer chemotherapy in the Department of Lower Gastrointestinal Surgery from October to December 2021(before the introduction of PBPM)and from May to August 2022(after the introduction of PBPM)were retrospectively studied. The proportion of clinical examinations performed, number of prescription questions, and time taken by pharmacists to solve the prescription questions before and after the introduction of PBPM were compared. Additionally, the number of modifications made in the medical record by pharmacists on behalf of doctors in response to the prescription questions was assessed. The proportion of clinical examinations performed(clinical examinations actually performed/clinical examinations that should have been performed)improved from 93.2%(260/279)before to 98.8%(405/410)after the introduction of PBPM(p<0.001). The number of prescription questions decreased from an average of 64.7(±11.9)per month before to an average of 29.5(±3.4)per month after the introduction of PBPM. The average number of modifications made in the medical record by pharmacists on behalf of the doctors in response to the prescription questions was 25.8(±5.4)per month after the introduction of PBPM. There was no significant difference before and after the introduction of PBPM in regard to the median(interquartile range)time taken by pharmacists to solve the prescription questions (before PBPM: 1.88 minutes per case[1.70-2.28 minutes]; after PBPM: 1.71 minutes per case[1.61-2.06 minutes][p= 0.75]). The increased proportion of clinical examinations performed after the implementation of PBPM may have improved the safety of cancer drug management, and the decreased number of prescription questions is speculated to have led to a reduction in physician workload.

BACKGROUND: Proton pump inhibitors (PPIs) reportedly reduce upper gastrointestinal bleeding (UGIB) in patients undergoing percutaneous coronary intervention (PCI). However, whether the benefits of PPIs differ in high-risk subgroups is unknown. METHODS AND RESULTS: Among 24,563 patients undergoing first PCI in the CREDO-Kyoto registry Cohort-2 and -3, we evaluated long-term effects of PPI for UGIB, defined as GUSTO moderate/severe bleeding, in several potential high-risk subgroups. In the study population, 45.6% of patients were prescribed PPIs. Over a median 5.6-year follow-up, PPIs were associated with lower adjusted risk of UGIB (hazard ratio [HR] 0.64; 95% confidence interval [CI] 0.50-0.80; P<0.001) and a non-significant but numerically lower risk of any gastrointestinal bleeding (HR 0.84; 95% CI 0.71-1.01; P=0.06). PPIs were not associated with a lower risk of GUSTO moderate/severe bleeding (HR 1.04; 95% CI 0.94-1.15; P=0.40) or a higher adjusted risk of myocardial infarction or ischemic stroke (HR 1.00; 95% CI 0.90-1.12; P=0.97), but were associated with higher adjusted mortality risk (HR 1.18; 95% CI 1.09-1.27; P<0.001). The effects of PPIs for UGIB, myocardial infarction or ischemic stroke, and all-cause death were consistent regardless of age, sex, acute coronary syndrome, high bleeding risk, oral anticoagulant use, and type of P2Y12inhibitor. CONCLUSIONS: PPIs were associated with a lower risk of UGIB and a neutral risk of ischemic events regardless of high-risk subgroup.
RESUMEN
Background: The prognostic implications of persistent low-grade inflammation in patients with chronic coronary syndrome (CCS) are underexplored. The REAL-CAD (Randomized Evaluation of Aggressive or Moderate Lipid Lowering Therapy with Pitavastatin in Coronary Artery Disease) study demonstrated the benefit of higher intensity pitavastatin in Japanese patients with CCS. Objectives: This prespecified subanalysis of the REAL-CAD study aimed to assess the prognostic effect of the persistent low-grade inflammation represented by high-sensitivity C-reactive protein (hs-CRP) in CCS patients. Methods: The present analysis involved patients without events until 6 months after randomization and whose hs-CRP levels were available at baseline and 6 months (n = 10,460). The primary endpoint was the composite of cardiovascular mortality, myocardial infarction, stroke, and unstable angina hospitalization. Landmark analyses evaluated the prognostic impact of continuous inflammation in 4 groups based on the median levels of hs-CRP (0.5 mg/L for both) at baseline and 6 months. The 4 groups included patient with persistently low, elevated (increased), reduced, and persistently high hs-CRP. Results: Adjusted Cox proportional hazard analyses demonstrated an increased risk of the primary endpoint in the group with persistently high hs-CRP when compared to the group with persistently low hs-CRP as a reference (adjusted HR: 1.48, 95% CI: 1.18-1.89; P = 0.001), but with a similar risk in the group with elevated (HR: 1.07, 95% CI: 0.77-1.49, P = 0.68) and reduced (HR: 0.92; 95% CI: 0.66-1.27; P = 0.60) hs-CRP. Conclusions: The study shows that persistent low-grade inflammation is associated with poor outcomes and underscores the need to address residual inflammatory risk in CCS patients.

RESUMEN
Background: There are few studies evaluating the prognostic prediction method in atrial fibrillation (AF) patients after bioprosthetic valve (BPV) replacement. The R2-CHA2DS2-VASc score is increasingly used for the prediction of cardiovascular (CV) events in patients with AF, device implantation, and acute coronary syndrome. We aimed to evaluate the predictive value of the R2-CHA2DS2-VASc score for future CV events in AF patients after BPV replacement. Methods and Results: The BPV-AF, an observational, multicenter, prospective registry, enrolled AF patients who underwent BPV replacement. The primary outcome measure was a composite of stroke, systemic embolism, CV events including heart failure requiring hospitalization, and cardiac death. A total of 766 patients was included in the analysis. The mean R2-CHA2DS2-VASc score was 5.7±1.8. Low (scores 0-1), moderate (scores 2-4), and high (scores 5-11) R2-CHA2DS2-VASc score groups consisted of 12 (1.6%), 178 (23.2%), and 576 (75.2%) patients, respectively. The median follow-up period was 491 (interquartile range 393-561) days. Kaplan-Meier analysis showed a higher incidence of the composite CV events in the high R2-CHA2DS2-VASc score group (log rank test; P<0.001). Multivariate Cox proportional hazards regression analysis revealed that the R2-CHA2DS2-VASc score as a continuous variable was an independent predictor of composite CV outcomes (hazard ratio 1.36; 95% confidence interval 1.18-1.55; P<0.001). Conclusions: The R2-CHA2DS2-VASc score is useful for CV risk stratification in AF patients after BPV replacement.

BACKGROUND AND AIMS: There was no previous trial comparing aspirin monotherapy with a P2Y12 inhibitor monotherapy following short dual antiplatelet therapy (DAPT) after percutaneous coronary intervention (PCI) with drug-eluting stents (DES). METHODS: In the STOPDAPT-3, patients with acute coronary syndrome (ACS) or high bleeding risk (HBR) were randomly assigned to either 1-month DAPT with aspirin and prasugrel followed by aspirin monotherapy (aspirin group) or 1-month prasugrel monotherapy followed by clopidogrel monotherapy (clopidogrel group). This secondary analysis compared aspirin monotherapy with clopidogrel monotherapy by the 30-day landmark analysis. The co-primary endpoints were the cardiovascular endpoint defined as a composite of cardiovascular death, myocardial infarction, definite stent thrombosis, or ischaemic stroke, and the bleeding endpoint defined as Bleeding Academic Research Consortium 3 or 5. RESULTS: Of 6002 assigned patients, 5833 patients (aspirin group: N = 2920 and clopidogrel group: N = 2913) were included in the 30-day landmark analysis. Median age was 73 (interquartile range 64-80) years, women 23.4%, ACS 74.6%, and HBR 54.1%. The assigned monotherapy was continued at 1 year in 87.5% and 87.2% in the aspirin and clopidogrel groups, respectively. The incidence rates beyond 30 days and up to 1 year were similar between the aspirin and clopidogrel groups for both cardiovascular endpoint (4.5 and 4.5 per 100 person-year, hazard ratio [HR] 1.00 [95% confidence interval (CI) 0.77-1.30], P = .97), and bleeding endpoint (2.0 and 1.9, HR 1.02 [95% CI 0.69-1.52], P = .92). CONCLUSIONS: Aspirin monotherapy compared to clopidogrel monotherapy was associated with similar cardiovascular and bleeding outcomes beyond 1 month and up to 1 year after PCI with DES.
RESUMEN
BACKGROUND: Ultimate Frisbee (Ultimate) has gained significant popularity. However, a comprehensive understanding of injury characteristics, including sex differences in injury location and onset, remains unclear. This study aimed to investigate the injury profile of male and female athletes using data from the Japanese University Athletic Association survey. METHODS: Data were collected through a web-based survey conducted between June and October 2022, focusing on injuries sustained within the past year. Athletes provided detailed information, including injury location, severity, and onset pattern. This study utilized data collected through the UNIVAS survey, offering insights into the injury landscape among female Ultimate athletes. The study examined factors influencing lower limb injuries, including training days and the nature of contact during play. RESULTS: A total of 116 athletes participated in the survey with 57 (49.1%) reporting injuries, of which 42 injuries involved the lower limbs. Lower-extremity injuries exhibited a higher likelihood of occurrence in female compared to male athletes (p = 0.05, φ = 0.18). Athletes with lower limb injuries demonstrated significantly more training days (p = 0.01, Cohen's d = 0.76). Non-contact injuries were more prevalent than contact injuries (p < 0.01, φ = 0.53), with non-contact injuries often causing prolonged interruptions in competition. CONCLUSIONS: Female Ultimate athletes experienced a high frequency of severe lower extremity injuries, particularly those stemming from non-contact incidents. More training days were an independent factor associated with these outcomes.
RESUMEN
BACKGROUND: Early arrhythmia recurrences commonly occur after atrial fibrillation (AF) ablation because of irritability and inflammation of left atrium. We hypothesized that short-term use of Saireito would be effective in reducing frequent atrial tachyarrhythmias in the early-phase post-ablation. METHODS: One hundred patients undergoing catheter ablation for symptomatic AF were randomly assigned to either a 30-day use of Saireito or control group. The primary endpoint was total number of episodes of frequent atrial tachyarrhythmias including definite recurrent AF and frequent premature atrial contractions during the 30-day treatment period post-ablation. RESULTS: Three (6.0%) out of 50 patients treated with Saireito discontinued the drug because of adverse symptoms. The Saireito group was associated with a numerically lower number of episodes of frequent atrial tachyarrhythmias than the control group (3.1 versus 5.2 times, P = 0.17). The mean daily episodes of frequent atrial tachyarrhythmias were significantly fewer in the Saireito group during Day-6 to Day-10 (0.12/day versus 0.27/day, P = 0.03), and during Day-11 to Day-15 (0.08/day versus 0.24/day, P = 0.001). The prevalence of adverse symptoms during the 30-day treatment period was significantly higher in the Saireito group (18.0% versus 2.0%, P = 0.005). CONCLUSIONS: Thirty-day use of Saireito following AF ablation was associated with a tendency toward reduced number of episodes of frequent atrial tachyarrhythmias during the treatment period, with more pronounced effect in the first two weeks.

The current guidelines for acute coronary syndrome (ACS) discourage the use of anticoagulation after percutaneous coronary intervention (PCI) without specific indications, although the recommendation is not well supported by evidence. In this post hoc analysis of the ShorT and OPtimal Duration of Dual AntiPlatelet Therapy-3 (STOPDAPT-3) trial, 30-day outcomes were compared between the 2 groups with and without post-PCI heparin administration among patients with ACS who did not receive mechanical support devices. The co-primary end points were the bleeding end point, defined as the Bleeding Academic Research Consortium type 3 or 5 bleeding, and the cardiovascular end point, defined as a composite of cardiovascular death, myocardial infarction, definite stent thrombosis, or ischemic stroke. Among 4,088 patients with ACS, 2,339 patients (57.2%) received post-PCI heparin. The proportion of patients receiving post-PCI heparin was higher among those with ST-elevation myocardial infarction compared with others (72.3% and 38.8%, p <0.001), and among patients with intraprocedural adverse angiographic findings compared with those without (67.6% and 47.5%, p <0.001). Post-PCI heparin compared with no post-PCI heparin was associated with a significantly increased risk of the bleeding end point (4.75% and 2.52%, adjusted hazard ratio 1.69, 95% confidence interval 1.15 to 2.46, p = 0.007) and a numerically increased risk of the cardiovascular end point (3.16% and 1.72%, adjusted hazard ratio 1.56, 95% confidence interval 0.98 to 2.46, p = 0.06). Higher hourly dose or total doses of heparin were also associated with higher incidence of both bleeding and cardiovascular events within 30 days. In conclusion, post-PCI anticoagulation with unfractionated heparin was frequently implemented in patients with ACS. Post-PCI heparin use was associated with harm in terms of increased bleeding without the benefit of reducing cardiovascular events. Trial identifier: STOPDAPT-3 ClinicalTrials.gov number, NCT04609111.

Unsymmetric boron (III) subphthalocyanines with a triselenole ring or a diselenete ring and eight fluoro groups were prepared by the reaction of 5,6-dicyano-4,7-diethylbenzo-[1,2,3]triselenole and tetrafluorophthalonitrile with trichloroborane in xylene. The reaction was accompanied by a contraction of the triselenole ring to the diselenete ring. The substrate, dicyanobenzo[1,2,3]triselenole, was prepared by a new procedure via a photolytic demethylenation reaction of 3,7-diethyl[1,3]diselenolophthalonitrile using a 10â W white LED light. While triselenolosubphthalocyanine was treated by triphenylphosphine to give the diselenete derivative, the reaction of diselenetosubphthalocyanine with Woolion's reagent produced the expanded triselenole ring. The diselenete derivative reacted with tetrakis(triphenylphosphine)platinum to yield the corresponding platinum complex with Se-Pt bonds. Q-band absorption for the products appeared at around λmax=590â nm in the UV-vis spectrum and weak emission was observed at about λe=620â nm. When diselenetosubphthalocyanine was treated with pentachloro antimonate in dichloromethane or sodium metal in hexane/tetrahydrofuran, the solution showed strong ESR signals. The structures of model compounds were optimized using the DFT method with the Gaussian 09 program at the B3LYP/6-31G (d, p) level.
RESUMEN
BACKGROUND: Current guidelines recommend direct oral anticoagulants (DOACs) and warfarin for patients with atrial fibrillation (AF) who have a bioprosthetic valve (BPV). However, the data related to elderly patients (aged ≥80 years) with BPV replacement and AF are limited. METHODS: This post-hoc subgroup analysis of a BPV-AF Registry enrolled 752 patients with BPV replacement and AF. The primary net outcome was a composite of cardiac death, stroke, systemic embolism, major bleeding, and cardiovascular events. RESULTS: Among 752 patients, 429 (57%) patients were ≥ 80 and 323 (43%) were < 80 years old. The higher risk in patients aged ≥80 than <80 years was significant for the net outcome (hazard ratio [HR], 2.04; 95% confidence interval [CI], 1.31-3.17; P = 0.001). After adjustment for confounders, there was no statistically significant difference between warfarin (reference) and DOAC users in the risk of net outcomes (adjusted HR, 1.26; 95% CI, 0.71-2.24; P = 0.44), stroke and systemic embolism (adjusted HR, 2.01; 95% CI, 0.48-8.38; P = 0.34), and major bleeding (adjusted HR, 0.73; 95% CI, 0.11-4.98; P = 0.75) in patients aged ≥80 years old as well as those aged <80 years. Among 489 warfarin users, the cumulative incidence of net outcomes tended to be higher in patients aged ≥80 than <80 years (12.2% vs. 5.7% at 1 year, log-rank P = 0.002). Among 263 DOAC users, however, it was similar between patients aged ≥80 and < 80 years. CONCLUSIONS: The present study demonstrated that DOAC showed similar efficacy and safety compared with warfarin even in elderly patients aged ≥80 years with BPV replacement and AF.

BACKGROUND: Initial hemodynamic status in patients with acute pulmonary embolism (PE) concerns their acute clinical outcomes. Nevertheless, the characteristics of initial hemodynamic dysfunction and acute mortality in PE patients with active cancer is still controversial. METHODS: We analyzed the data of 1715 PE patients in the COMMAND VTE Registry to compare initial hemodynamic dysfunction, management strategies, and mortality outcomes at 30 days after PE diagnosis between patients with and without active cancer (N = 393 and N = 1322). RESULTS: The patients with active cancer showed lower prevalence of right ventricular dysfunction (35.4% vs. 49.5%, P < 0.001), shock (6.4% vs. 11.6%, P = 0.003), and cardiac arrest (1.8% vs. 5.5%, P = 0.002) at PE diagnosis, compared with those without. The patients with active cancer less frequently received systemic thrombolysis (4.1% vs. 12.6%, P < 0.001) than those without. There was no significant difference in the cumulative 30-day incidence of PE-related death between patients with and without active cancer (4.1% vs. 4.2%, P = 0.89). The cumulative 30-day incidence of all-cause death was significantly higher in patients with active cancer than in those without (11.5% vs. 4.9%, P < 0.001). CONCLUSIONS: PE patients with active cancer less frequently present with initial hemodynamic dysfunction at PE diagnosis, compared with those without. Nevertheless, PE patients with active cancer still show a similar risk of PE-related death and a higher risk of all-cause death at 30 days after PE diagnosis, suggesting the importance of prudent management for this patient population even if their initial hemodynamic status are not compromised.

Methods: The Health, Clinic, and Education Information Evaluation Institute and Real World Data Co., Ltd. began developing the Real World Database in 2015. This is an electronic medical record database linked to claims data and discharge abstract data from medical institutions in Japan. The institutions agreed to collect data from 218 medical institutions as of June 2021. Results: In 2019, 82 medical institutions provided data, which showed that 2,184,666 patients received treatment at medical institutions. There were also 334,437 inpatients with at least one hospital stay and 2,011,628 outpatients with at least one visit. More than 200 laboratory test results were available. Discussion: This database is a potential data source for producing descriptive studies, comparative effectiveness studies, studies of adverse effects, and prediction studies. Conclusions: The Real World Database provides an opportunity and strategy to produce real-world evidence for Japan.
RESUMEN
For almost two decades, 12-month dual antiplatelet therapy (DAPT) in acute coronary syndrome (ACS) has been the only class I recommendation on DAPT in American and European guidelines, which has resulted in 12-month durations of DAPT therapy being the most frequently implemented in ACS patients undergoing percutaneous coronary intervention (PCI) across the globe. Twelve-month DAPT was initially grounded in the results of the CURE (Clopidogrel in Unstable Angina to Prevent Recurrent Events) trial, which, by design, studied DAPT versus no DAPT rather than the optimal DAPT duration. The average DAPT duration in this study was 9 months, not 12 months. Subsequent ACS studies, which were not designed to assess DAPT duration, rather its composition (aspirin with prasugrel or ticagrelor compared with clopidogrel) were further interpreted as supportive evidence for 12-month DAPT duration. In these studies, the median DAPT duration was 9 or 15 months for ticagrelor and prasugrel, respectively. Several subsequent studies questioned the 12-month regimen and suggested that DAPT duration should either be fewer than 12 months in patients at high bleeding risk or more than 12 months in patients at high ischemic risk who can safely tolerate the treatment. Bleeding, rather than ischemic risk assessment, has emerged as a treatment modifier for maximizing the net clinical benefit of DAPT, due to excessive bleeding and no clear benefit of prolonged treatment regimens in high bleeding risk patients. Multiple DAPT de-escalation treatment strategies, including switching from prasugrel or ticagrelor to clopidogrel, reducing the dose of prasugrel or ticagrelor, and shortening DAPT duration while maintaining monotherapy with ticagrelor, have been consistently shown to reduce bleeding without increasing fatal or nonfatal cardiovascular or cerebral ischemic risks compared with 12-month DAPT. However, 12-month DAPT remains the only class-I DAPT recommendation for patients with ACS despite the lack of prospectively established evidence, leading to unnecessary and potentially harmful overtreatment in many patients. It is time for clinical practice and guideline recommendations to be updated to reflect the totality of the evidence regarding the optimal DAPT duration in ACS.

BACKGROUND: The effects of aspirin-free strategy on bleeding and cardiovascular events in patients undergoing percutaneous coronary intervention with oral anticoagulation (OAC) have not been fully elucidated. METHODS AND RESULTS: We conducted the prespecified subgroup analysis based on the use of OAC, including vitamin K antagonist and direct oral anticoagulants, within 7 days before percutaneous coronary intervention in the STOPDAPT-3 (Short and Optimal Duration of Dual Antiplatelet Therapy-3) trial, which randomly compared prasugrel monotherapy (2984 patients) to dual antiplatelet therapy (DAPT) with prasugrel and aspirin (2982 patients) in patients with acute coronary syndrome or high bleeding risk. The coprimary end points were major bleeding events (Bleeding Academic Research Consortium types 3 or 5) and cardiovascular events (a composite of cardiovascular death, myocardial infarction, definite stent thrombosis, or ischemic stroke) at 1 month. Among 5966 study patients, there were 530 patients (8.9%) with OAC (no aspirin: N=248, and DAPT: N=282) and 5436 patients (91.1%) without OAC (no aspirin: N=2736, and DAPT: N=2700). Regardless of the use of OAC, the effects of no aspirin compared with DAPT were not significant for the bleeding end point (OAC: 4.45% and 4.27%, hazard ratio [HR], 1.04 [95% CI, 0.46-2.35]; no-OAC: 4.47% and 4.75%, HR, 0.94 [95% CI, 0.73-1.20]; P for interaction=0.82), and for the cardiovascular end point (OAC: 4.84% and 3.20%, HR, 1.53 [95% CI, 0.64-3.62]; no-OAC: 4.06% and 3.74%, HR, 1.09 [95% CI 0.83-1.42]; P for interaction =0.46). CONCLUSIONS: The no-aspirin strategy compared with the DAPT strategy failed to reduce major bleeding events irrespective of the use of OAC. There was a numerical excess risk of the no-aspirin strategy relative to the DAPT strategy for cardiovascular events in patients with OAC.
