  • Derivation and validation of the predicting bleeding complications in patients undergoing stent implantation and subsequent dual antiplatelet therapy (PRECISE-DAPT) score : a pooled analysis of individual-patient datasets from clinical trials
  • 2017

    • Background: Dual antiplatelet therapy (DAPT) with aspirin plus a P2Y(12) inhibitor prevents ischaemic events after coronary stenting, but increases bleeding. Guidelines support weighting bleeding risk before the selection of treatment duration, but no standardised tool exists for this purpose.Methods: A total of 14 963 patients treated with DAPT after coronary stenting-largely consisting of aspirin and clopidogrel and without indication to oral anticoagulation-were pooled at a single-patient level from eight multicentre randomised clinical trials with independent adjudication of events. Using Cox proportional hazards regression, we identified predictors of out-of-hospital Thrombosis in Myocardial Infarction (TIMI) major or minor bleeding stratified by trial, and developed a numerical bleeding risk score. The predictive performance of the novel score was assessed in the derivation cohort and validated in patients treated with percutaneous coronary intervention from the PLATelet inhibition and patient Outcomes (PLATO) trial (n=8595) and BernPCI registry (n=6172). The novel score was assessed within patients randomised to different DAPT durations (n=10 081) to identify the effect on bleeding and ischaemia of a long (12-24 months) or short (3-6 months) treatment in relation to baseline bleeding risk.Findings: The PRECISE-DAPT score (age, creatinine clearance, haemoglobin, white-blood-cell count, and previous spontaneous bleeding) showed a c-index for out-of-hospital TIMI major or minor bleeding of 0.73 (95% CI 0.61-0.85) in the derivation cohort, and 0.70 (0.65-0.74) in the PLATO trial validation cohort and 0.66 (0.61-0.71) in the BernPCI registry validation cohort. A longer DAPT duration significantly increased bleeding in patients at high risk (score >= 25), but not in those with lower risk profiles (p(interaction)=0.007), and exerted a significant ischaemic benefit only in this latter group.Interpretation: The PRECISE-DAPT score is a simple five-item risk score, which provides a standardised tool for the prediction of out-of-hospital bleeding during DAPT. In the context of a comprehensive clinical evaluation process, this tool can support clinical decision making for treatment duration.

  • Dual Antiplatelet Therapy Duration Based on Ischemic and Bleeding Risks After Coronary Stenting
  • 2019
  • Ingår i: Journal of the American College of Cardiology. - : Elsevier BV. - 0735-1097 .- 1558-3597. ; 73:7, s. 741-754

    • BACKGROUNDComplex percutaneous coronary intervention (PCI) is associated with higher ischemic risk, which can be mitigated by long-term dual antiplatelet therapy (DAPT). However, concomitant high bleeding risk (HBR) may be present, making it unclear whether short-or long-term DAPT should be prioritized.OBJECTIVESThis study investigated the effects of ischemic (by PCI complexity) and bleeding (by PRECISE-DAPT [PREdicting bleeding Complications in patients undergoing stent Implantation and SubsequEnt Dual AntiPlatelet Therapy] score) risks on clinical outcomes and on the impact of DAPT duration after coronary stenting.METHODSComplex PCI was defined as $ 3 stents implanted and/or $ 3 lesions treated, bifurcation stenting and/or stent length > 60 mm, and/or chronic total occlusion revascularization. Ischemic and bleeding outcomes in high ($ 25) or nonhigh (< 25) PRECISE-DAPT strata were evaluated based on randomly allocated duration of DAPT.RESULTSAmong 14,963 patients from 8 randomized trials, 3,118 underwent complex PCI and experienced a higher rate of ischemic, but not bleeding, events. Long-term DAPT in non-HBR patients reduced ischemic events in both complex (absolute risk difference:-3.86%; 95% confidence interval:-7.71 to thorn0.06) and noncomplex PCI strata (absolute risk difference:-1.14%; 95% confidence interval:-2.26 to-0.02), but not among HBR patients, regardless of complex PCI features. The bleeding risk according to the Thrombolysis In Myocardial Infarction scale was increased by long-term DAPT only in HBR patients, regardless of PCI complexity.CONCLUSIONS Patients who underwent complex PCI had a higher risk of ischemic events, but benefitted from long-term DAPT only if HBR features were not present. These data suggested that when concordant, bleeding, more than ischemic risk, should inform decision-making on the duration of DAPT.

  • Comparison of Dabigatran Plus a P2Y12 Inhibitor With Warfarin-Based Triple Therapy Across Body Mass Index in RE-DUAL PCI.
  • 2020
  • Ingår i: American Journal of Medicine. - : Elsevier BV. - 0002-9343 .- 1555-7162. ; 133:11, s. 1302-1312

    • BACKGROUND: Body mass index (BMI) affects drug levels of nonvitamin K antagonist oral anticoagulants. We sought to assess whether BMI affected outcomes in the RE-DUAL PCI trial.METHODS: RE-DUAL PCI (NCT02164864) evaluated the safety and efficacy of a dual-antithrombotic-therapy regimen using dabigatran (110 mg or 150 mg twice daily and a P2Y12 platelet antagonist) in comparison with triple therapy of warfarin, aspirin, and a P2Y12 platelet inhibitor in 2725 patients with atrial fibrillation who had undergone percutaneous coronary intervention (PCI). We compared the risk of first International Society on Thrombosis and Haemostasis (ISTH)-defined major or clinically relevant nonmajor bleeding events (primary endpoint) and the composite of death, myocardial infarction, stroke, systemic embolism, or unplanned revascularization (main efficacy endpoint) in relation to baseline BMI.RESULTS: Median (range) BMI was 28.1 (14-66) kg/m2. Dabigatran dual therapy versus warfarin triple therapy had relevantly and similarly lower rates of bleeding at both 110 mg and 150 mg twice-daily doses, irrespective of BMI. Thromboembolic event rates appeared consistent across categories of BMI, including those <25 and ≥35 kg/m2 (P for interaction: 0.806 and 0.279, respectively).CONCLUSIONS: The reduction in bleeding with dabigatran dual therapy compared with warfarin triple therapy in patients here evaluated appears consistent across BMI categories.

  • Ingår i: European heart journal. Cardiovascular pharmacotherapy. - : Oxford University Press (OUP). - 2055-6845 .- 2055-6837. ; 5:4, s. 200-206

    • In PEGASUS-TIMI 54, ticagrelor significantly reduced the risk of the composite of major adverse cardiovascular (CV) events by 15-16% in stable patients with a prior myocardial infarction (MI) 1-3 years earlier. We report the efficacy and safety in the subpopulation recommended for treatment in the European (EU) label, i.e. treatment with 60 mg b.i.d. initiated up to 2 years from the MI, or within 1 year after stopping previous adenosine diphosphate receptor inhibitor treatment.Of the 21 162 patients enrolled in PEGASUS-TIMI 54, 10 779 patients were included in the primary analysis for this study, randomized to ticagrelor 60 mg (n = 5388) or matching placebo (n = 5391). The cumulative proportions of patients with events at 36 months were calculated by the Kaplan-Meier (KM) method. The composite of CV death, MI, or stroke occurred less frequently in the ticagrelor group (7.9% KM rate vs. 9.6%), hazard ratio (HR) 0.80 [95% confidence interval (CI) 0.70-0.91; P = 0.001]. Ticagrelor also reduced the risk of all-cause mortality, HR 0.80 (0.67-0.96; P = 0.018). Thrombolysis in myocardial infarction major bleeding was more frequent in the ticagrelor group 2.5% vs. 1.1%; HR 2.36 (1.65-3.39; P < 0.001). The corresponding HR for fatal or intracranial bleeding was 1.17 (0.68-2.01; P = 0.58).In PEGASUS-TIMI 54, treatment with ticagrelor 60 mg as recommended in the EU label, was associated with a relative risk reduction of 20% in CV death, MI, or stroke. Thrombolysis in myocardial infarction major bleeding was increased, but fatal or intracranial bleeding was similar to placebo. There appears to be a favourable benefit-risk ratio for long-term ticagrelor 60 mg in this population.http://www.clinicaltrials.gov NCT01225562.

  • Balance of benefit and risk of ticagrelor in patients with diabetes and stable coronary artery disease according to bleeding risk assessment with the CRUSADE score : Data from THEMIS and THEMIS PCI
  • 2022
  • Ingår i: American Heart Journal. - : Elsevier BV. - 0002-8703 .- 1097-6744. ; 249, s. 23-33
  • Tidskriftsartikel (refereegranskat)abstract
    • Background The THEMIS trial demonstrated that in high-risk patients with stable coronary artery disease and diabetes without previous myocardial infarction or stroke, ticagrelor, in addition to aspirin, reduced the incidence of ischemic events but increased major bleeding. Identification of patients who could derive the greatest net benefit from the addition of ticagrelor appears important. We used the CRUSADE bleeding risk score to risk stratify the THEMIS population. Methods The population was divided into tertiles: score <= 22, 23 to 33, and >= 34. In each tertile, primary efficacy (composite of cardiovascular death, myocardial infarction, or stroke) and safety (TIMI major bleeding) outcomes were analyzed. NACE (net adverse clinical events) was defined as the irreversible harm composite, in which all-cause death, myocardial infarction, stroke, amputations, fatal bleeds, and intracranial hemorrhage were counted. Results Patients in the lower risk tertile experienced fewer ischemic events with ticagrelor than placebo, whereas there was no significant benefit from ticagrelor in the other tertiles (P-interaction = .008). Bleeding rates were consistently increased with ticagrelor across all tertiles (P-interaction = .79). Ticagrelor reduced NACE in the first tertile (HR = 0.74, 95% CI = 0.61-0.90) but not in the others (HR = 1.03, 95% CI = 0.86-1.23 and HR = 1.05, 95% CI = 0.91-1.22, respectively; P-interaction = .012). Conclusions In patients with stable coronary artery disease and diabetes without a history of myocardial infarction or stroke, only those at the lower end of the bleeding risk spectrum according to the CRUSADE score derived net benefit from ticagrelor.

  • The effect of sex on the efficacy and safety of dual antithrombotic therapy with dabigatran versus triple therapy with warfarin after PCI in patients with atrial fibrillation (a RE-DUAL PCI subgroup analysis and comparison to other dual antithrombotic therapy trials)
  • 2021
  • Ingår i: Clinical Cardiology. - : Wiley. - 0160-9289 .- 1932-8737. ; 44:7, s. 1002-1010
  • Tidskriftsartikel (refereegranskat)abstract
    • BackgroundThe RE-DUAL PCI trial demonstrated that in patients with nonvalvular atrial fibrillation (AF) undergoing percutaneous coronary intervention (PCI), dual therapy with dabigatran and a P2Y12 inhibitor, either clopidogrel or ticagrelor, reduced the risk of bleeding without an increased risk of thromboembolic events as compared to triple therapy with warfarin in addition to a P2Y12 inhibitor and aspirin. What remains unclear is whether this effect is consistent between males and females undergoing PCI.HypothesisThe reduction in risk of bleeding without increased risk of thromboembolic events with dual therapy with dabigatran and a P2Y12 inhibitor in comparison to triple therapy with warfarin, a P2Y12 inhibitor and aspirin is consistent in females and males.MethodsThe primary safety endpoint was the first International Society on Thrombosis and Hemostasis (ISTH) major bleeding event (MBE) or clinically relevant non-major bleeding event (CRNMBE). The efficacy endpoint was the composite of death, thromboembolic event (stroke, myocardial infarction, and systemic embolism) or unplanned revascularization. Cox proportional hazard regression analyses were applied to calculate corresponding hazard ratios and interaction p values for each endpoint.ResultsA total of 655 women and 2070 men were enrolled. The risk of major or CRNM bleeding was lower with both dabigatran 110 mg dual therapy and dabigatran 150 mg dual therapy compared with warfarin triple therapy in female and male patients (for 110 mg: females: HR 0.69, 95% CI 0.47–1.01, males: HR 0.46, 95% CI 0.37–0.59, interaction p value: 0.084 and for 150 mg: females HR 0.74, 95% CI 0.48–1.16, males HR 0.71, 95% CI 0.56–0.90, interaction p value: 0.83). There was also no detectable difference in the composite efficacy endpoint of death, thromboembolic events or unplanned revascularization between dabigatran dual therapy and warfarin triple therapy, with no statistically significant interaction between sex and treatment (interaction p values: 0.73 and 0.72, respectively).ConclusionsConsistent with the overall study results, the risk of bleeding was lower with dabigatran 110 mg and 150 mg dual therapy compared with warfarin triple therapy, and risk of thromboembolic events was comparable with warfarin triple therapy independent of the patient's sex.

  • Antithrombotic agents for secondary prevention after acute coronary syndromes : A systematic review and network meta-analysis
  • 2017
  • Ingår i: International Journal of Cardiology. - : ELSEVIER IRELAND LTD. - 0167-5273 .- 1874-1754. ; 241, s. 87-96

    • Background: Nine oral antithrombotic medications currently available in the United States and Europe have been studied in clinical trials for secondary prevention of cardiac events following acute coronary syndrome (ACS). Few combinations of these medications have been directly compared, and studies have used multiple different comparator regimens.Methods: We performed a systematic review and network meta-analysis of randomized controlled trials evaluating one or more available oral antithrombotic therapies in patients with ACS or prior myocardial infarction (MI). Co-primary outcomes were all-cause and cardiovascular mortality compared with imputed placebo and aspirin monotherapy.Results: Forty-seven studies (196,057 subjects) met inclusion criteria and were included in the systematic review. Almost all studies tested either aspirin monotherapy compared with placebo or a combination of antithrombotic agents that included aspirin. Nearly all regimens reduced all-cause and cardiovascular mortality compared with imputed placebo. However, compared with imputed aspirin monotherapy, only combination therapy with aspirin plus ticagrelor was associated with lower cardiovascular mortality (OR 0.80, 95% CI 0.68-0.93), and triple therapy with aspirin, clopidogrel, and very low dose rivaroxaban was associated with lower all-cause mortality (OR 0.67, 95% CI 0.49-0.90). Major bleeding was increased 45-95% with dual antithrombotic therapy, and 2-6-fold with triple therapy.Conclusion: Few combinations of antithrombotic therapy were associated with a reduction inmortality compared with aspirin monotherapy, highlighting the difficulty in clinical interpretation of composite ischemic endpoints. Future studies may need to focus on limiting the number of antithrombotic therapies tested in combination to best balance ischemic event reduction and bleeding.

    • It is unclear whether coronary artery bypass grafting (CABG) improves survival compared with medical therapy (MT) in patients with stable coronary artery disease (CAD). The aim of this analysis was to perform an individual-patient data-pooled meta-analysis of contemporary randomized controlled trials that compared CABG and MT in patients with stable CAD.A systematic search was performed in January 2021 to identify randomized controlled trials enrolling adult patients with stable CAD, randomized to CABG or MT. Only trials using at least aspirin, beta-blockers, and statins in the MT arm were included. Individual patient data were obtained from all eligible studies and pooled. The primary outcome was all-cause mortality.Four trials involving 2523 patients (1261 CABG; 1262 MT) were included with a median follow-up of 5.6 (4.0-9.2) years. CABG was associated with increased risk of all-cause mortality within 30 days (hazard ratio [HR], 4.81; 95% confidence interval [CI], 1.95-11.83) but subsequent reduction in the long-term risk of death (HR, 0.79; 95% CI, 0.69-0.89). As such, the cumulative 10-year mortality rate was lower in patients treated with CABG compared with MT (45.1% vs 51.7%, respectively; odds ratio, 0.70; 95% CI, 0.58-0.85). Age and race were significant treatment effect modifier (interaction P = .003 for both).In patients with stable CAD, initial allocation to CABG was associated with greater periprocedural risk of death but improved long-term survival compared with MT. The survival advantage for CABG became significant after the fourth postoperative year and was particularly pronounced in younger and non-White patients.

    • Aims: Of patients with atrial fibrillation (AF), approximately 10% undergo percutaneous coronary intervention (PCI). We studied the safety and efficacy of dual vs. triple antithrombotic therapy (DAT vs. TAT) in this population.Methods and results: A systematic review and meta-analysis was conducted using PubMed, Embase, EBSCO, Cochrane database of systematic reviews, Web of Science, and relevant meeting abstracts for Phase 3, randomized trials that compared DAT vs. TAT in patients with AF following PCI. Four trials including 5317 patients were included, of whom 3039 (57%) received DAT. Compared with the TAT arm, Thrombolysis in Myocardial Infarction (TIMI) major or minor bleeding showed a reduction by 47% in the DAT arm [4.3% vs. 9.0%; hazard ratio (HR) 0.53, 95% credible interval (CrI) 0.36–0.85, I2 = 42.9%]. In addition, there was no difference in the trial-defined major adverse cardiac events (MACE) (10.4% vs. 10.0%, HR 0.85, 95% CrI 0.48–1.29, I2 = 58.4%), or in individual outcomes of all-cause mortality, cardiac death, myocardial infarction, stent thrombosis, or stroke between the two arms.Conclusion: Compared with TAT, DAT shows a reduction in TIMI major or minor bleeding by 47% with comparable outcomes of MACE. Our findings support the concept that DAT may be a better option than TAT in many patients with AF following PCI.
