    • The diagnostic evaluation of acute chest pain has been augmented in recent years by advances in the sensitivity and precision of cardiac troponin assays, new biomarkers, improvements in imaging modalities, and release of new clinical decision algorithms. This progress has enabled physicians to diagnose or rule-out acute myocardial infarction earlier after the initial patient presentation, usually in emergency department settings, which may facilitate prompt initiation of evidence-based treatments, investigation of alternative diagnoses for chest pain, or discharge, and permit better utilization of healthcare resources. A non-trivial proportion of patients fall in an indeterminate category according to rule-out algorithms, and minimal evidence-based guidance exists for the optimal evaluation, monitoring, and treatment of these patients. The Cardiovascular Round Table of the ESC proposes approaches for the optimal application of early strategies in clinical practice to improve patient care following the review of recent advances in the early diagnosis of acute coronary syndrome. The following specific 'indeterminate' patient categories were considered: (i) patients with symptoms and high-sensitivity cardiac troponin <99th percentile; (ii) patients with symptoms and high-sensitivity troponin <99th percentile but above the limit of detection; (iii) patients with symptoms and high-sensitivity troponin >99th percentile but without dynamic change; and (iv) patients with symptoms and high-sensitivity troponin >99th percentile and dynamic change but without coronary plaque rupture/erosion/dissection. Definitive evidence is currently lacking to manage these patients whose early diagnosis is 'indeterminate' and these areas of uncertainty should be assigned a high priority for research.

  • Early invasive vs conservative treatment strategies in women and men with unstable angina and non-ST-segment elevation myocardial infarction : a meta-analysis
  • 2008

    • CONTEXT: Although an invasive strategy is frequently used in patients with non-ST-segment elevation acute coronary syndromes (NSTE ACS), data from some trials suggest that this strategy may not benefit women. OBJECTIVE: To conduct a meta-analysis of randomized trials to compare the effects of an invasive vs conservative strategy in women and men with NSTE ACS. DATA SOURCES: Trials were identified through a computerized literature search of the MEDLINE and Cochrane databases (1970-April 2008) using the search terms invasive strategy, conservative strategy, selective invasive strategy, acute coronary syndromes, non-ST-elevation myocardial infarction, and unstable angina. STUDY SELECTION: Randomized clinical trials comparing an invasive vs conservative treatment strategy in patients with NSTE ACS. DATA EXTRACTION: The principal investigators for each trial provided the sex-specific incidences of death, myocardial infarction (MI), and rehospitalization with ACS through 12 months of follow-up. DATA SYNTHESIS: Data were combined across 8 trials (3075 women and 7075 men). The odds ratio (OR) for the composite of death, MI, or ACS for invasive vs conservative strategy in women was 0.81 (95% confidence interval [CI], 0.65-1.01; 21.1% vs 25.0%) and in men was 0.73 (95% CI, 0.55-0.98; 21.2% vs 26.3%) without significant heterogeneity between sexes (P for interaction = .26). Among biomarker-positive women, an invasive strategy was associated with a 33% lower odds of death, MI, or ACS (OR, 0.67; 95% CI, 0.50-0.88) and a nonsignificant 23% lower odds of death or MI (OR, 0.77; 95% CI, 0.47-1.25). In contrast, an invasive strategy was not associated with a significant reduction in the triple composite end point in biomarker-negative women (OR, 0.94; 95% CI, 0.61-1.44; P for interaction = .36) and was associated with a nonsignificant 35% higher odds of death or MI (OR, 1.35; 95% CI, 0.78-2.35; P for interaction = .08). Among men, the OR for death, MI, or ACS was 0.56 (95% CI, 0.46-0.67) if biomarker-positive and 0.72 (95% CI, 0.51-1.01) if biomarker-negative (P for interaction = .09). CONCLUSIONS: In NSTE ACS, an invasive strategy has a comparable benefit in men and high-risk women for reducing the composite end point of death, MI, or rehospitalization with ACS. In contrast, our data provide evidence supporting the new guideline recommendation for a conservative strategy in low-risk women.

  • Dual-pathway inhibition for secondary and tertiary antithrombotic prevention in cardiovascular disease
  • 2020
  • Ingår i: Nature Reviews Cardiology. - : Springer Science and Business Media LLC. - 1759-5002 .- 1759-5010. ; 17:4, s. 242-257

    • Advances in antiplatelet therapies for patients with cardiovascular disease have improved patient outcomes over time, but the challenge of balancing the risks of ischaemia and bleeding remains substantial. Moreover, many patients with cardiovascular disease have a residual risk of ischaemic events despite receiving antiplatelet therapy. Therefore, novel strategies are needed to prevent clinical events through mechanisms beyond platelet inhibition and with an acceptable associated risk of bleeding. The advent of non-vitamin K antagonist oral anticoagulants, which attenuate fibrin formation by selective inhibition of factor Xa or thrombin, has renewed the interest in dual-pathway inhibition strategies that combine an antiplatelet agent with an anticoagulant drug. In this Review, we highlight the emerging pharmacological rationale and clinical development of dual-pathway inhibition strategies for the prevention of atherothrombotic events in patients with different manifestations of cardiovascular disease, such as coronary artery disease, cerebrovascular disease and peripheral artery disease. Many patients with cardiovascular disease have a residual risk of ischaemic events despite receiving antiplatelet therapy. In this Review, Angiolillo and colleagues discuss the pharmacological rationale and clinical development of dual-pathway inhibition strategies for the prevention of atherothrombotic events in patients with cardiovascular disease.
