  • Outcomes after planned invasive or conservative treatment strategy in patients with non-ST-elevation acute coronary syndrome and a normal value of high sensitivity troponin at randomisation : A Platelet Inhibition and Patient Outcomes (PLATO) trial biomarker substudy.
  • 2017
  • Ingår i: European Heart Journal. - : Oxford University Press (OUP). - 2048-8726 .- 2048-8734. ; 6:6, s. 500-510

    • AIMS: Current guidelines for patients with non-ST-elevation acute coronary syndrome (NSTE-ACS) recommend early invasive treatment in intermediate-to-high risk patients based on medical history, electrocardiogram (ECG) and elevated troponin. Patients with normal levels of cardiac troponin measured with a high-sensitivity method (cTnT-hs) might not benefit from early invasive procedures.METHODS AND RESULTS: In this Prospective Randomized Platelet Inhibition and Patient Outcomes (PLATO) blood-core substudy, 1232 patients presented with NSTE-ACS had a high sensitivity cardiac troponin T (cTnT-hs) level <99(th) percentile (<14 ng/l) at randomisation. The outcomes in relation to a planned invasive (n=473) vs planned conservative treatment (n=759), were evaluated by adjusted Cox proportional hazard analyses. In patients with a normal cTnT-hs at randomisation, regardless of randomised treatment, a planned invasive vs conservative treatment was associated with a 2.3-fold higher risk (7.3% vs 3.4%, p=0.0028) for cardiovascular (CV) death or myocardial infarction (MI), driven by higher rates of procedure-related MI (3.4% vs 0.1%), while there were no differences in rates of CV death (1.3% vs 1.3%, p=0.72) or spontaneous MI (3.0% vs 2.1%, p=0.28). There were significantly more major bleeds (hazard ratio (HR) 2.98, p<0.0001), mainly due to coronary artery bypass graft (CABG)-related (HR 4.05, p<0.0001) and non-CABG procedural-related major bleeding events (HR 5.31, p=0.0175), however there were no differences in non-procedure-related major bleeding (1.5% vs 1.9%, p=0.45). Findings were consistent for patients with a normal cTnI-hs at randomisation.CONCLUSIONS: In patients with NSTE-ACS and normal cTnT-hs, a planned early invasive treatment strategy was associated with increased rates of procedure-related MI and bleeding but no differences in long-term spontaneous MI, non-procedure-related bleeding or mortality.

  • Safety and efficacy of dual vs. triple antithrombotic therapy in patients with atrial fibrillation following percutaneous coronary intervention : a systematic review andmeta-analysis of randomized clinical trials
  • 2018
  • Ingår i: European Heart Journal. - : Oxford University Press (OUP). - 0195-668X .- 1522-9645. ; 39:19, s. 1726-
  • Forskningsöversikt (refereegranskat)abstract
    • 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.

  • Growth Differentiation Factor 15 Predicts All-Cause Morbidity and Mortality in Stable Coronary Heart Disease
  • 2017
  • Ingår i: Clinical Chemistry. - : Oxford University Press (OUP). - 0009-9147 .- 1530-8561. ; 63:1, s. 325-333
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Higher growth differentiation factor 15 (GDF-15) concentrations are associated with cardiovascular (CV) and non-CV morbidity and mortality. However, information on associations between GDF-15 and the risk of specific CV and non-CV events in stable coronary heart disease (CHD) patients is limited.METHODS: In 14 577 patients with stable CHD participating in the Stabilization of Atherosclerotic Plaque by Initiation of Darapladib Therapy Trial (STABILITY), GDF-15 and other prognostic biomarkers (N-terminal pro-B-type natriuretic peptide, high-sensitivity troponin T, cystatin C, and high-sensitivity C-reactive protein) were measured. In adjusted Cox regression models, the associations between GDF-15 and the composite CV end point [CV death, myocardial infarction (MI), and stroke], as well as other CV and non-CV events, were assessed.RESULTS: The median concentration (interquartile range) of GDF-15 at baseline was 1253 (915-1827) ng/L. The hazard ratio for the composite end point for the highest compared to the lowest quartile of GDF-15 was 1.8 (95% CI, 1.5-2.2); for CV death, 2.63 (1.9-3.6); for sudden death, 3.06 (1.9-4.8); for heart failure (HF) death, 4.3 (1.3-14); for cancer death, 2.5 (1.3-4.7); for hospitalization for HF, 5.8 (3.2-10); for MI 1.4 (95% CI, 1.1-1.9); and for stroke, 1.8 (95% CI, 1.1-2.8). After adjustment for other prognostic biomarkers, GDF-15 remained significantly associated with all outcomes except for MI.CONCLUSIONS: In stable CHD, GDF-15 was independently associated with CV, non-CV, and cancer mortality, as well as with MI and stroke. When also adjusting for other prognostic biomarkers, the associations to all fatal and nonfatal events were maintained except for MI. Information on GDF-15, therefore, might be helpful when assessing the risk of adverse outcomes in patients with stable CHD. ClinicalTrials.gov Identifier: NCT00799903.

    • BackgroundEvaluation of cardiovascular prognosis in patients with stable coronary heart disease is based on clinical characteristics and biomarkers indicating dysglycemia, dyslipidemia, renal dysfunction, and possibly cardiac dysfunction. Inflammation plays a key role in atherosclerosis, but the association between inflammatory biomarkers and clinical outcomes is less studied in this population.Methods and ResultsOverall, 15 828 patients with coronary heart disease in the STABILITY (Stabilization of Atherosclerotic Plaque by Initiation of Darapladib Therapy) trial werer and randomized to treatment with darapladib or placebo and observed for a median of 3.7 years. In 14 611 patients, levels of interleukin-6 (IL-6) and high-sensitivity C-reactive protein were measured in plasma samples: median levels were2.1 (interquartile range, 1.4-3.2) ng/Land1.3 (interquartile range, 0.6-3.1) mg/L, respectively. Associations between continuous levels or quartile groups and adjudicated outcomes were evaluated by spline graphs and Cox regression adjusted for clinical factors and cardiovascular biomarkers. IL-6 was associated with increased risk of major adverse cardiovascular events (quartile 4 versus quartile 1 hazard ratio [HR], 1.60; 95% confidence interval [CI], 1.30-1.97; P< 0.0001); cardiovascular death (HR, 2.15; 95% CI, 1.53-3.04; P< 0.0001); myocardial infarction (HR, 1.53; 95% CI, 1.14-2.04; P< 0.05); all-cause mortality (HR, 2.11; 95% CI, 1.62-2.76; P< 0.0001); and risk of hospitalization for heart failure (HR, 2.28; 95% CI, 1.34-3.89; P< 0.001). Cancer death was doubled in the highest IL-6 quartile group (HR, 2.34; 95% CI, 1.20-4.53; P< 0.05). High-sensitivity C-reactive protein was associated with both cardiovascular and non-cardiovascular events in the unadjusted model, but these did not remain after multivariable adjustments.ConclusionsIL-6, an upstream inflammatory marker, was independently associated with the risk of major adverse cardiovascular events, cardiovascular and all-cause mortality, myocardial infarction, heart failure, and cancer mortality in patients with stable coronary heart disease. IL-6 might reflect a pathophysiological process involved in the development of these events.

  • Renal Function and Outcomes With Dabigatran Dual Antithrombotic Therapy in Atrial Fibrillation Patients After PCI
  • 2019
  • Ingår i: JACC. - : ELSEVIER SCIENCE INC. - 1936-8798 .- 1876-7605. ; 12:16, s. 1553-1561
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVES: The study sought to evaluate the effect of dabigatran dual therapy versus warfarin triple therapy across categories of renal function in the RE-DUAL PCI (Randomized Evaluation of Dual Antithrombotic Therapy with Dabigatran versus Triple Therapy with Warfarin in Patients with Nonvalvular Atrial Fibrillation Undergoing Percutaneous Coronary Intervention) trial.BACKGROUND: The RE-DUAL PCI (NCT02164864) trial of patients with atrial fibrillation undergoing percutaneous coronary intervention reported that dabigatran dual therapy (110 or 150 mg twice daily, plus clopidogrel or ticagrelor) reduced the primary endpoint of major bleeding events (MBE) or clinically relevant nonmajor bleeding events (CRNMBE) compared with warfarin triple therapy, with noninferiority in overall thromboembolic events.METHODS: Risk of a first MBE or CRNMBE and the composite of death or thromboembolic event (DTE) or unplanned revascularization were evaluated in 2,725 patients according to baseline creatinine clearance (CrCl) categories: 30 to <50, 50 to <80, and >= 80 ml/min.RESULTS: Compared with warfarin, dabigatran 110 mg dual therapy reduced risk of MBE or CRNMBE across all categories of CrCl (p for interaction = 0.19). Dabigatran 150 mg dual therapy reduced risk of MBE or CRNMBE regardless of the CrCl category (p for interaction = 0.31). Risk of DTE or unplanned revascularization was similar to warfarin triple therapy for dabigatran 110 mg dual therapy across all CrCl categories. Dabigatran 150 mg dual therapy versus warfarin triple therapy had similar risk for DTE or unplanned revascularization in patients with CrCl 30 to <80 ml/min and lower risk at CrCl >= 80 ml/min (p for interaction = 0.02).CONCLUSIONS: In the RE-DUAL PCI trial, dabigatran dual therapy reduced bleeding events versus warfarin triple therapy irrespective of renal function, with overall similar risks of thromboembolic events but lower risks with dabigatran 150 mg in patients with normal CrCl.

  • Relationship of stroke and bleeding risk profiles to efficacy and safety of dabigatran dual therapy versus warfarin triple therapy in atrial fibrillation after percutaneous coronary intervention : An ancillary analysis from the RE-DUAL PCI trial
  • 2019
  • Ingår i: American Heart Journal. - : MOSBY-ELSEVIER. - 0002-8703 .- 1097-6744. ; 212, s. 13-22
  • Tidskriftsartikel (refereegranskat)abstract
    • Background In the RE-DUAL PCI trial of patients with atrial fibrillation (AF) who underwent percutaneous coronary intervention (PCI), dabigatran dual therapy (110 or 150 mg bid, plus clopidogrel or ticagrelor) reduced International Society on Thrombosis and Haemostasis bleeding events compared with warfarin triple therapy, with noninferiority in overall thromboembolic events. This analysis assessed outcomes in relation to patient bleeding and stroke risk profiles, based on the modified HAS-BLED and CHA(2)DS(2)-VASc scores. Methods The primary endpoint, major bleeding event (MBE) or clinically relevant nonmajor bleeding event (CRNMBE), was compared across study arms in patients categorized by modified HAS-BLED score 0-2 or >= 3. The composite endpoint of death, thromboembolic event, and unplanned revascularization rates was compared in patients categorized by CHA(2)DS(2)-VASc score 0-1, 2, or >= 3. Results Risk of MBE or CRNMBE was lower with dabigatran dual therapy (both doses) versus warfarin triple therapy, irrespective of modified HAS-BLED category (treatment-by-subgroup interaction P-value 0.584 and 0.273 for dabigatran 110 and 150 mg dual therapy, respectively, vs warfarin). Risk of the composite thromboembolic endpoint was similar across CHA(2)DS(2)-VASc categories and consistent with overall study results (interaction P-value 0.739 and 0.075 for dabigatran 110 and 150 mg dual therapy, respectively, vs warfarin). Higher HAS-BLED scores were associated with higher risks of bleeding in AF patients after PCI in a treatment-independent analysis. Conclusion Dabigatran dual therapy reduced bleeding events irrespective of bleeding risk category and demonstrated similar efficacy regardless of stroke risk category when compared with warfarin triple therapy.

  • Platelet-related biomarkers and their response to inhibition with aspirin and p2y12-receptor antagonists in patients with acute coronary syndrome
  • 2017
  • Ingår i: Journal of Thrombosis and Thrombolysis. - : Springer Science and Business Media LLC. - 0929-5305 .- 1573-742X. ; 44:2, s. 145-153

    • The PLATelet inhibition and patient Outcomes (PLATO) trial showed that treatment with ticagrelor reduced the rate of death due to vascular causes, myocardial infarction and stroke when compared to clopidogrel in patients with ST-elevation or non-ST-elevation acute coronary syndrome (ACS). While the comparative benefit of ticagrelor over clopidogrel increased over time, event rates accrued in both groups during the study period. The purpose of our biomarker-based exploratory analysis was to determine whether long-term platelet inhibition may be associated with platelet adaptation. A sample of 4000 participants from the PLATO trial also consented to participate in a prospectively designed biomarker substudy. Blood samples were procured at baseline, immediately prior to hospital discharge and at 1 and 6 months. Markers of platelet activity, including platelet count, serum CD40-ligand and soluble P-selectin were analyzed. Mean levels were compared at discharge, 1 and 6 months following study drug initiation-first for all patients and subsequently stratified by treatment group. A linear mixed model was used to estimate the short-term change rate (baseline to 1 month) and long-term change rate (1-6 months) for each biomarker. A Cox proportional hazards model was used to calculate hazard ratios for each change in biomarker over the two time periods examined: baseline to 1 month and 1 to 6 months. Prior to randomized treatment (baseline), sCD40 ligand and sP-selectin levels were elevated above the normal range of the assay (0.39 and 33.5 A μg/L, respectively). The mean level of each biomarker was significantly different at 1 month compared to baseline (p < 0.0001). When stratified by treatment group, at 1 month patients treated with ticagrelor had a larger increase in platelet count compared to those treated with clopidogrel (p < 0.0001). Similarly, when comparing biomarker levels for all patients at 6 months with those at 1 month, each differed significantly (p < 0.05). There was no significant difference between treatment groups during this time period. The rate of change for both platelet count and sP-selectin were significantly different between baseline and 1 month when compared to the 1 to 6-month time period (p < 0.0001). When comparing treatment groups, the rate of increase in platelets from baseline to 1 month was greater for patients treated with ticagrelor (p < 0.0001). This was no longer observed in the 1 to 6-month interval. Using a Cox proportional hazard model, the increase in platelet count from 1 to 6 months was associated with ischemic-thrombotic events, while sCD40 ligand decrease from 1 to 6 months was associated with hemorrhagic events. There were no differences between treatment groups for the associations with clinical endpoints. Dynamic changes in platelet count, sCD-40 ligand and sP-selectin occur over time among patients with ACS. Platelet-directed therapy with a P2Y12 receptor inhibitor in combination with aspirin modestly impacts the expression of these biomarkers. Platelet count and sCD40 ligand may offer modest overall predictive value for future ischemic-thrombotic or hemorrhagic clinical events, respectively. The existence of a platelet adaptome and its overall clinical significance among patients at risk for thrombotic events will require a more in-depth and platelet-biology specific investigation.

  • Genetically predicted longer telomere length is associated with increased risk of B-cell lymphoma subtypes
  • 2016
  • Ingår i: Human Molecular Genetics. - : Oxford University Press (OUP). - 0964-6906 .- 1460-2083. ; 25:8, s. 1663-1676
  • Tidskriftsartikel (refereegranskat)abstract
    • Evidence from a small number of studies suggests that longer telomere length measured in peripheral leukocytes is associated with an increased risk of non-Hodgkin lymphoma (NHL). However, these studies may be biased by reverse causation, confounded by unmeasured environmental exposures and might miss time points for which prospective telomere measurement would best reveal a relationship between telomere length and NHL risk. We performed an analysis of genetically inferred telomere length and NHL risk in a study of 10 102 NHL cases of the four most common B-cell histologic types and 9562 controls using a genetic risk score (GRS) comprising nine telomere length-associated single-nucleotide polymorphisms. This approach uses existing genotype data and estimates telomere length by weighing the number of telomere length-associated variant alleles an individual carries with the published change in kb of telomere length. The analysis of the telomere length GRS resulted in an association between longer telomere length and increased NHL risk [four B-cell histologic types combined; odds ratio (OR) = 1.49, 95% CI 1.22-1.82, P-value = 8.5 x 10(-5)]. Subtype-specific analyses indicated that chronic lymphocytic leukemia or small lymphocytic lymphoma (CLL/SLL) was the principal NHL subtype contributing to this association (OR = 2.60, 95% CI 1.93-3.51, P-value = 4.0 x 10(-10)). Significant interactions were observed across strata of sex for CLL/SLL and marginal zone lymphoma subtypes as well as age for the follicular lymphoma subtype. Our results indicate that a genetic background that favors longer telomere length may increase NHL risk, particularly risk of CLL/SLL, and are consistent with earlier studies relating longer telomere length with increased NHL risk.

  • Dabigatran Dual Therapy Versus Warfarin Triple Therapy Post-PCI in Patients With Atrial Fibrillation and Diabetes
  • 2019
  • Ingår i: JACC. - : ELSEVIER SCIENCE INC. - 1936-8798 .- 1876-7605. ; 12:23, s. 2346-2355
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVES: The aim of this study was to evaluate dabigatran dual therapy versus warfarin triple therapy in patients with or without diabetes mellitus in the RE-DUAL PCI (Randomized Evaluation of Dual Antithrombotic Therapy With Dabigatran Versus Triple Therapy With Warfarin in Patients With Nonvalvular Atrial Fibrillation Undergoing Percutaneous Coronary Intervention) trial.BACKGROUND: It is unclear whether dual therapy is as safe and efficacious as triple therapy in patients with atrial fibrillation with diabetes following percutaneous coronary intervention.METHODS: In RE-DUAL PCI, 2,725 patients with atrial fibrillation (993 with diabetes) who had undergone PCI were assigned to warfarin triple therapy (warfarin, clopidogrel or ticagrelor, and aspirin) or dabigatran dual therapy (dabigatran 110 mg or 150 mg twice daily and clopidogrel or ticagrelor). Median follow-up was 13 months. The primary outcome was the composite of major bleeding or clinically relevant nonmajor bleeding, and the main efficacy outcome was the composite of death, thromboembolic events, or unplanned revascularization.RESULTS: Among patients with diabetes, the incidence of major bleeding or clinically relevant nonmajor bleeding was 15.2% in the dabigatran 110 mg dual therapy group versus 27.5% in the warfarin triple therapy group (hazard ratio [HR]: 0.48; 95% confidence interval [CI] 0.35 to 0.67) and 23.8% in the dabigatran 150 mg dual therapy group versus 25.1% in the warfarin triple therapy group (HR: 0.87; 95% CI: 0.62 to 1.22). Risk for major bleeding or clinically relevant nonmajor bleeding was also reduced with both dabigatran doses among patients without diabetes (dabigatran 110 mg dual therapy: HR: 0.54; 95% CI: 0.42 to 0.70; dabigatran 150 mg dual therapy: HR: 0.63; 95% CI: 0.48 to 0.83). Risk for the efficacy endpoint was comparable between treatment groups for both patients with and those without diabetes. No interaction between treatment and diabetes subgroup could be observed, either for bleeding or for composite efficacy endpoints.CONCLUSIONS: In this subgroup analysis, dabigatran dual therapy had a lower risk for bleeding and a comparable rate of the efficacy endpoint compared with warfarin triple therapy in patients with atrial fibrillation with or without diabetes following percutaneous coronary intervention.
