  • European practice patterns for antiplatelet management in NSTE-ACS patients : Results from the REal-world ADoption survey focus on Acute antiPlatelet Treatment (READAPT) survey
  • 2023
  • Ingår i: International Journal of Cardiology. - 0167-5273. ; 386, s. 8-16
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: The 2020 European Society of Cardiology (ESC) guidelines for the diagnosis and management of patients with non-ST elevation-acute coronary syndrome (NSTE-ACS) recommend early invasive coronary angiography in high-risk patients and no routine pre-treatment with oral P2Y12 receptor inhibitor in NSTE-ACS patients prior to defining coronary anatomy. Objective: To assess the implementation of this recommendation in the real-life setting. Methods: A web-survey in 17 European countries collected physician profiles and their perceptions of the diagnosis, medical and invasive management of NSTE-ACS patients at their hospital. A sample size of at least 1100 responders permitted the estimation of proportions with a precision of at least ±3.0%. Results: Among the 3024 targeted participants, 1154 provided valid feedback defined as a 50% response rate of answers to the survey questions. Overall, >60% of the participants declared full implementation of the guidelines at their institution. The time delay from admission to coronary angiography and PCI was reported to be <24 h in over 75% of the hospitals while pre-treatment was intended in >50% of NSTE-ACS patients. Ad-hoc percutaneous coronary intervention (PCI) was performed in >70% of the cases while intravenous platelet inhibition was rarely used (<10%). Between countries differences in practice patterns for antiplatelet management for NSTE-ACS were observed, suggesting heterogeneous implementation of the guidelines. Conclusions: This survey indicates that the implementation of 2020 NSTE-ACS guidelines on early invasive management and pre-treatment is heterogeneous, potentially due by local logistical constraints.

  • Temporal biomarker profiling reveals longitudinal changes in risk of death or myocardial infarction in Non-ST-segment elevation acute coronary syndrome
  • 2017
  • Ingår i: Clinical Chemistry. - : Oxford University Press (OUP). - 0009-9147 .- 1530-8561. ; 63:7, s. 1214-1226
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: There are conflicting data on whether changes in N-terminal pro-B-type natriuretic peptide (NT-proBNP) and high-sensitivity C-reactive protein (hs-CRP) concentrations between time points (delta NT-proBNP and hs-CRP) are associated with a change in prognosis. METHODS: We measured NT-proBNP and hs-CRP at 3 time points in 1665 patients with non-ST-segment elevation acute coronary syndrome (NSTEACS). Cox proportional hazards was applied to the delta between temporal measurements to determine the continuous association with cardiovascular events. Effect estimates for delta NT-proBNP and hs-CRP are presented per 40% increase as the basic unit of temporal change. RESULTS: Median NT-proBNP was 370.0 (25th, 75th percentiles, 130.0, 996.0), 340.0 (135.0, 875.0), and 267.0 (111.0, 684.0) ng/L; and median hs-CRP was 4.6 (1.7, 13.1), 1.9 (0.8, 4.5), and 1.8 (0.8, 4.4) mg/L at baseline, 30 days, and 6 months, respectively. The deltas between baseline and 6 months were the most prognostically informative. Every 40% increase of delta NTproBNP (baseline to 6 months) was associated with a 14% greater risk of cardiovascular death (adjusted hazard ratio (HR) 1.14, 95% CI, 1.03-1.27) and with a 14% greater risk of all-cause death (adjusted HR 1.14, 95% CI, 1.04 -1.26), while every 40% increase of delta hs- CRP (baseline to 6 months) was associated with a 9% greater risk of the composite end point (adjusted HR 1.09, 95% CI, 1.02-1.17) and a 10% greater risk of myocardial infarction (adjusted HR 1.10, 95%, CI 1.00 -1.20). CONCLUSIONS: Temporal changes in NT-proBNP and hs-CRP are quantitatively associated with future cardiovascular events, supporting their role in dynamic risk stratification of NSTEACS.

  • Platelet Function During Extended Prasugrel and Clopidogrel Therapy for Patients With ACS Treated Without Revascularization The TRILOGY ACS Platelet Function Substudy
  • 2012
  • Ingår i: JAMA: The Journal of the American Medical Association. - : American Medical Association (AMA). - 1538-3598. ; 308:17, s. 1785-1794
  • Tidskriftsartikel (refereegranskat)abstract
    • Context The relationship of platelet function testing measurements with outcomes in patients with acute coronary syndromes (ACS) initially managed medically without revascularization is unknown. Objective To characterize the differences and evaluate clinical outcomes associated with platelet reactivity among patients with ACS treated with clopidogrel or prasugrel. Design, Setting, and Patients Patients with medically managed unstable angina or non-ST-segment elevation myocardial infarction were enrolled in the TRILOGY ACS trial (2008 to 2011) comparing clopidogrel vs prasugrel. Of 9326 participants, 27.5% were included in a platelet function substudy: 1286 treated with prasugrel and 1278 treated with clopidogrel. Interventions Aspirin with either prasugrel (10 or 5 mg/d) or clopidogrel (75 mg/d); those 75 years or older and younger than 75 years but who weighed less than 60 kg received a 5-mg prasugrel maintenance dose. Main Outcome Measures Platelet reactivity, measured in P2Y(12) reaction units (PRUs), was performed at baseline, at 2 hours, and at 1, 3, 6, 12, 18, 24, and 30 months after randomization. The primary efficacy end point was a composite of cardiovascular death, myocardial infarction, or stroke through 30 months. Results Among participants younger than 75 years and weighing 60 kg or more, the median PRU values at 30 days were 64 (interquartile range [IQR], 33-128) in the prasugrel group vs 200 (IQR, 141-260) in the clopidogrel group (P<.001), a difference that persisted through all subsequent time points. For participants younger than 75 years and weighing less than 60 kg, the median 30-day PRU values were 139 (IQR, 86-203) for the prasugrel group vs 209 (IQR, 148-283) for the clopidogrel group (P<.001), and for participants 75 years or older, the median PRU values were 164 (IQR, 105-216) for the prasugrel group vs 222 (IQR, 148-268) for the clopidogrel group (P<.001). At 30 months the rate of the primary efficacy end point was 17.2% (160 events) in the prasugrel group vs 18.9% (180 events) in the clopidogrel group (P=.29). There were no significant differences in the continuous distributions of 30-day PRU values for participants with a primary efficacy end point event after 30 days (n=214) compared with participants without an event (n=1794; P=.07) and no significant relationship between the occurence of the primary efficacy end point and continuous PRU values (adjusted hazard ratio [HR] for increase of 60 PRUs, 1.03; 95% CI, 0.96-1.11; P=.44). Similar findings were observed with 30-day PRU cut points used to define high on-treatment platelet reactivity-PRU more than 208 (adjusted HR, 1.16; 95% CI, 0.89-1.52, P=.28) and PRU more than 230 (adjusted HR, 1.20; 95% CI, 0.90-1.61; P=.21). Conclusions Among patients with ACS without ST-segment elevation and initially managed without revascularization, prasugrel was associated with lower platelet reactivity than clopidogrel, irrespective of age, weight, and dose. Among those in the platelet substudy, no significant differences existed between prasugrel vs clopidogrel in the occurence of the primary efficacy end point through 30 months and no significant association existed between platelet reactivity and occurrence of ischemic outcomes.

  • Translational platelet research in patients with coronary artery disease: hat are the rnalor knowledge gaps?
  • 2012
  • Ingår i: Thrombosis and Haemostasis. - 0340-6245. ; 108:1, s. 12-20
  • Forskningsöversikt (refereegranskat)abstract
    • Translational platelet function investigations performed in the percutaneous coronary intervention (PCI)-treated population receiving clopidogrel have identified high platelet reactivity to ADP (HPR) as a major risk factor for both acute as well as long-term ischaemic event occurrence, including stent thrombosis. Recent studies have highlighted the relation of single nucleotide polymorphisms of genes involved in clopidogrel absorption and metabolism to reduced pharmacokinetic and pharmacodynamic responses to clopidogrel. CYP2C19 loss-of-function (LoF) allele carriage has been associated with increased thrombotic risk in the PCI population. However, there is no information regarding the utility of platelet function testing to predict outcomes in patients with stable coronary artery disease and in medically managed patients with acute coronary syndromes. Additionally, few studies have included longitudinal assessment of platelet function to assess a potential time-dependent relation to ischaemic event occurrence and no phase-III antiplatelet-therapy trial has included a large enough platelet function sub-study to examine the relation between on-treatment platelet reactivity, bleeding, and ischaemic event occurrence. Therefore, futher studies are needed to delineate the role of platelet function testing across the spectrum of symptomatic coronary artery disease.

  • Net Clinical Benefit of Non-Vitamin K Antagonist vs Vitamin K Antagonist Anticoagulants in Elderly Patients with Atrial Fibrillation
  • 2019
  • Ingår i: American Journal of Medicine. - : Elsevier BV. - 0002-9343. ; 132:6, s. 5-757
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: The risks of thromboembolic and hemorrhagic events in patients with atrial fibrillation both increase with age; therefore, net clinical benefit analyses of anticoagulant treatments in the elderly population are crucial to guide treatment. We evaluated the 1-year clinical outcomes with non-vitamin-K antagonist and vitamin K antagonist oral anticoagulants (NOACs vs VKAs) in elderly (≥75 years) patients with atrial fibrillation in a prospective registry setting. Methods: Data on 3825 elderly patients were pooled from the PREFER in AF and PREFER in AF PROLONGATION registries. The primary outcome was the incidence of the net composite endpoint, including major bleeding and ischemic cardiovascular events on NOACs (n = 1556) compared with VKAs (n = 2269). Results: The rates of the net composite endpoint were 6.6%/year with NOACs vs 9.1%/year with VKAs (odds ratio [OR] 0.71; 95% confidence interval [CI], 0.51-0.99; P =.042). NOAC therapy was associated with a lower rate of major bleeding compared with VKA use (OR 0.58; 95% CI, 0.38-0.90; P =.013). Ischemic events were nominally reduced too (OR 0.71; 95% CI, 0.51-1.00; P =.050). Major bleeding with NOACs was numerically lower in higher-risk patients with low body mass index (BMI; OR 0.50; 95% CI, 0.22-1.12; P =.07) or with age ≥85 years (OR 0.44; 95% CI, 0.13-1.49; P =.17). Conclusions: Our real-world data indicate that, compared with VKAs, NOAC use is associated with a better net clinical benefit in elderly patients with atrial fibrillation, primarily due to lower rates of major bleeding. Major bleeding with NOACs was numerically lower also in higher-risk patients with low BMI or age ≥85 years.

  • Thromboembolic and bleeding risk in obese patients with atrial fibrillation according to different anticoagulation strategies
  • 2020
  • Ingår i: International Journal of Cardiology. - : Elsevier BV. - 0167-5273. ; 318, s. 67-73
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Data on the relationship between body mass index (BMI), thromboembolic events (TEE) and bleeding in patients with atrial fibrillation (AF) are controversial, and further evidence on the risk of such events in obese patients with AF receiving different anticoagulant therapies (OAC) is needed. Methods and results: We divided a total of 9330 participants from the prospective PREFER in AF and PREFER in AF PROLONGATION registries into BMI quartiles at baseline. Outcome measures were TEE and major bleeding complications at the 1-year follow-up. Without OAC, there was a ≥6-fold increase of TEE in the 4th vs other BMI quartiles (P =.019). OAC equalized the rates of TEE across different BMI strata. The occurrence of major bleeding was highest in patients with BMI in the 1st as well as in the 4th BMI quartile [OR 1.69, 95% CI 1.03–2.78, P =.039 and OR 1.86, 95% CI 1.13–3.04, P =.014 vs those in the 3rd quartile, respectively]. At propensity score-adjusted analysis, the incidence of TEE and major bleeding in obese patients receiving non-vitamin K antagonist oral anticoagulants (NOACs) or vitamin K-antagonist anticoagulants (VKAs) was similar (P ≥.34). Conclusions: Our real-world data suggest no obesity paradox for TEE in patients with AF. Obese patients are at higher risk of TEE, and here OAC dramatically reduces the risk of events. We here found a comparable clinical outcome with NOACs and VKAs in obese patients. Low body weight and obesity were also associated with bleeding, and therefore OAC with the best safety profile should be considered in this setting.
