Introduction: Clopidogrel is an anticoagulant commonly used in the prehospital environment for the management of ST-elevation myocardial infarction (STEMI). Some ambulance services have incorporated this into their treatment regimens; however, others hold a variety of alternative pharmacological interventions. Aims: The purpose of this study is to examine and determine the pharmacological efficacy and safety of clopidogrel in the management of patients with STEMI and assess whether ambulance services should use the drug as part of standard practice. Methods: A literature review was conducted to identify articles relating to the administration of clopidogrel in the prehospital setting. Fourteen peer-reviewed journal articles and eight clinical practice guidelines from international ambulance services were included in this review. Results: According to this literature review, clopidogrel has been deemed safe, effective and practical for widespread use in the prehospital environment for the management of STEMI. However, some disagreement has arisen over whether clopidogrel is a more favourable anticoagulant than ticagrelor and prasugrel. Conclusion: Anticoagulants such as clopidogrel should be strongly considered as a standard treatment regimen in the prehospital management of STEMI across international jurisdictions.

IntroductionThe unfavourable influence of morphine on the pharmacokinetics of ticagrelor resulting in weaker and retarded antiplatelet effect in patients with acute coronary syndrome (ACS) has been previously shown. Replacing morphine with methoxyflurane, a potent, non-opioid analgesic agent, that does not weaken or delay the effect of antiplatelet agents may improve the clinical efficacy of treatment of patients with ACS.MethodsThe ANEMON-SIRIO 3 study was designed as a multicentre, open-label, phase II, randomised clinical trial aimed to test the analgesic efficacy and safety of methoxyflurane in patients with ACS. The study population will comprise patients with ST-elevation myocardial infarction or non-ST-elevation ACS admitted to the study centres with typical chest pain requiring analgesic treatment. Before percutaneous coronary intervention (PCI) for the patients with index ACS will be randomly assigned in 1:1 ratio to receive methoxyflurane administered by inhalation, or to obtain morphine administered intravenously. Analgesic treatment will be followed by 300 mg loading dose of aspirin and 180 mg loading dose of ticagrelor. Patients will be assessed with regard to pain intensity according to the Numeric Pain Rating Scale at baseline, 3 min after study drug administration and immediately after PCI. Moreover, patients will be actively monitored with regard to the occurrence of side effects of evaluated therapies, as well as adverse events that may be related to insufficient platelet inhibition (no-reflow phenomenon assessed immediately after PCI, administration of GPIIb/IIIa inhibitors during PCI, acute stent thrombosis).Ethics and disseminationThe study will be conducted in six Polish clinical centres from the beginning of in accordance with the ethical standards of the institutional research committee and with the 1964 Helsinki declaration and its later amendments or comparable ethical standards.Trial registration detailsClinicalTrials.gov, NCT04476173.

<b><i>Background:</i></b> In patients with ST-elevation myocardial infarction (STEMI), C-reactive protein (CRP) levels are associated with larger infarct size, transmural extent, and poor function of left ventricle and independently predict 30-day mortality. CRP-apheresis following STEMI showed to be feasible, safe, and has significant beneficial effect both on myocardial infarction size and wall motion. To the best of our knowledge, this is only the second published clinical evaluation of the efficacy and safety of selective CRP-apheresis in the STEMI treatment using Spectra-Optia and Pentrasorb CRP-adsorber systems. <b><i>Case Report:</i></b> A 53-year-old female was referred with anterior STEMI. After percutaneous coronary intervention, patient received standard post-STEMI therapy according to current guidelines. Selective therapeutic plasma exchange (TPE) was performed using Spectra-Optia (Terumo BCT; USA) and Pentrasorb CRP-adsorber (Pentracor GmbH; Germany) systems. Antecubital veins were used for vascular access and acid-citrate-dextrose solution (ACD formula A; total volume = 1,026 mL) was utilized as anticoagulant. The volume of processed blood was 15,600 mL. The removed “natural” plasma (total volume = 8,329 mL) was replaced with CRP-depleted autologous plasma (total volume = 8,085 mL). This intensive TPE-treatment was well tolerated, without adverse effects, or complications. The CRP plasma levels were: initial = 4.2 mg/L 6 h after acute myocardial infarction (AMI), pre-apheresis = 16.4 mg/L, and post-apheresis = 4.59 mg/L (CRP-depletion = 72%). There were neither significant changes observed in biochemistry nor any alterations in plasma hemostatic activity investigated before and after CRP-adsorption performed. <b><i>Conclusion:</i></b> Early performed CRP-apheresis is a promising innovative therapeutic approach for STEMI treatment that could provide a reduced size of infarction zone – with inferior occurrence of heart failure after AMI. However, precise and complete evaluation of the efficacy and safety of this treatment requires further multicenter randomized and larger clinical studies.

Acute myocardial infarction during pregnancy or the postpartum period is rare. We report a case of a 39-year-old postpartum woman who developed non-ST-elevation myocardial infarction due to severe diffuse coronary vasospasm. To our knowledge, this is the first case of angiographically evidenced coronary vasospasm, in a postpartum woman, with resistance to intracoronary nitroglycerin.
