Eligibility Criteria
Inclusion
- Aged over 18 years
- Admitted to hospital with non-ST-elevation ACS and plan for either coronary angiography with a view to PCI if appropriate or PCI following coronary angiography at a referring hospital
- Current treatment with aspirin and ticagrelor or, if ticagrelor is not tolerated, prasugrel (DAPT)
- Ability to give informed consent
Exclusion
- Treatment with antiplatelet medication apart from aspirin, ticagrelor, prasugrel or clopidogrel in the last 10 days (e.g. dipyridamole, abciximab, tirofiban).
- Planned use of a glycoprotein IIb/IIIa antagonist for the PCI procedure.
- Patients with haemodynamic instability, shock or angiographic evidence of intracoronary thrombus.
- Current use of an oral anticoagulant (e.g. warfarin, dabigatran, rivaroxaban, apixaban).
- Clinically significant liver disease.
- Contraindication or allergy to unfractionated heparin.
- Receiving immunosuppressant medication (eg. cyclosporin, tacrolimus, mycophenolate, azathioprine).
- Administration of doses of low molecular weight heparin or fondaparinux in the 12 hours preceding PCI.
- Known severe left ventricular dysfunction (ejection fraction \<30%).
- Culprit lesion in left main coronary artery.
- Women of childbearing potential unless pregnancy has been excluded during the index hospital admission.
- Known serum creatinine above upper limit of local reference range.
- Subjects with known active chronic inflammatory disease, e.g. systemic lupus erythematosus, rheumatoid arthritis, seropositive arthropathies and known seropositivity to HIV, Hepatitis B or Hepatitis C.
- Severely diseased, excessively tortuous or calcified coronary vessels that increase the risk of snaring the LBS.
- Culprit lesion in a coronary vessel with a reference diameter of less than 2.5 mm.
- Need to cross a region of coronary vessel that contains a stent.
- Evidence of ongoing sepsis.
- Receiving a non-steroidal anti-inflammatory drug (NSAID) apart from aspirin, including selective COX2 inhibitors ('coxibs') and including regular or intermittent/as required use.
- Receiving a strong inhibitor of CYP3A4 (eg, ketoconazole, itraconazole, voriconazole, telithromycin, clarithromycin \[but not erythromycin or azithromycin\], nefazadone, ritonavir, saquinavir, nelfinavir, indinavir, atanazavir, or over 1 litre daily of grapefruit juice).
- Receiving simvastatin or lovastatin at doses higher than 40 mg daily.
- Receiving a CYP3A substrate with a narrow therapeutic index (e.g. cyclosporine or quinidine).
- Receiving a strong inducer of CYP3A (e.g. rifampin/rifampicin, rifabutin, phenytoin, carbamazepine, phenobarbital).
- Current or recent (within 30 days) participation in a clinical trial of a drug or device or any other clinical study that might influence the results or safety of the study.
- Any factor precluding ability to comply with follow-up.
- Any other factor judged by the investigator or treating physician to preclude enrolment in the study.
