In patients ≥ 60yrs with acute ST-elevation myocardial infarction randomised within 3 hours of onset of symptoms the efficacy and safety of a strategy of early fibrinolytic treatment with half-dose tenecteplase and additional antiplatelet therapy with a loading dose of 300 mg clopidogrel, aspirin and coupled with antithrombin therapy followed by catheterisation within 6-24 hours or rescue coronary intervention as required, will be compared to a strategy of primary PCI with a P2Y12 antagonist and antithrombin treatment according to local standards.

Procedure Coronary angiography

Coronary angiography followed by PCI or CABG if required, rescue PCI if required

Procedure Primary PCI

Primary PCI accoring to local standards

Drug Tenecteplase

Half dose Tenecteplase

  • Other names: TNKase, Metalyse

Drug Clopidogrel

300 mg p.o. initial loading dose. Maintenance dose of 75 mg p.o. once daily. The maintenance dose of Clopidogrel (75 mg p.o. per day) should be continued for 1 year.

Pharmaco-invasive strategy Experimental

Half-dose tenecteplase and additional antiplatelet therapy with a loading dose of 300 mg clopidogrel, aspirin and coupled with antithrombin therapy followed by coronary angiography within 6-24 hours or rescue coronary intervention as required.

Standard primary PCI Active Comparator

Primary PCI with a P2Y12 antagonist and antithrombin treatment according to local standards.

Criteria

Inclusion Criteria:

Age equal or greater than 60 years
Onset of symptoms < 3 hours prior to randomisation

12-lead ECG indicative of an acute STEMI (ST-elevation will be measured from the J point; scale: 1 mm per 0.1 mV):

≥ 2 mm ST-elevation across 2 contiguous precordial leads (V1-V6) or leads I and aVL for a minimum combined total of ≥ 4 mm ST-elevation or
≥ 2 mm ST-elevation in 2 contiguous inferior leads (II, III, aVF) for a minimum combined total of ≥ 4 mm ST-elevation
Informed consent received

Exclusion Criteria:

1. Expected performance of PCI < 60 minutes from diagnosis (qualifying ECG) or inability to arrive at the catheterisation laboratory within 3 hours
Previous CABG
Left bundle branch block or ventricular pacing
Patients with cardiogenic shock - Killip Class 4
Patients with a body weight < 55 kg (known or estimated)
Uncontrolled hypertension, defined as sustained blood pressure ≥ 180/110 mm Hg (systolic BP ≥ 180 mm Hg and/or diastolic BP ≥ 110 mm Hg) prior to randomisation
Known prior stroke or TIA
Recent administration of any i.v. or s.c. anticoagulation within 12 hours, including unfractionated heparin, enoxaparin, and/or bivalirudin or current use of oral anticoagulation (i.e. warfarin or a NOACs)
Active bleeding or known bleeding disorder/diathesis
Known history of central nervous system damage (i.e. neoplasm, aneurysm, intracranial or spinal surgery) or recent trauma to the head or cranium (i.e. < 3 months)
Major surgery, biopsy of a parenchymal organ, or significant trauma within the past 2 months (this includes any trauma associated with the current myocardial infarction)
Clinical diagnosis associated with increased risk of bleeding including known active peptic ulceration and/or neoplasm with increased bleeding risk
Prolonged cardiopulmonary resuscitation (> 2 minutes) within the past 2 weeks
Known acute pericarditis and/or subacute bacterial endocarditis
Known acute pancreatitis or known severe hepatic dysfunction, including hepatic failure, cirrhosis, portal hypertension (oesophageal varices) and active hepatitis
Dementia
Known severe renal insufficiency
Previous enrolment in this study or treatment with an investigational drug or device under another study protocol in the past 7 days
Known allergic reactions to tenecteplase, clopidogrel, enoxaparin and aspirin
Inability to follow the protocol and comply with follow-up requirements or any other reason that the investigator feels would place the patient at increased risk if the investigational therapy is initiated.
