From the Guidelines
Yes, antithrombotic medications are essential in the management of ST-elevation myocardial infarction (STEMI). The standard antithrombotic regimen for STEMI includes dual antiplatelet therapy (DAPT) with aspirin and a P2Y12 inhibitor, as recommended by the 2017 ESC guidelines for the management of acute myocardial infarction in patients presenting with ST-segment elevation 1.
Key Recommendations
- Antiplatelet therapy with low-dose aspirin (75–100 mg) is indicated 1, and DAPT in the form of aspirin plus ticagrelor or prasugrel (or clopidogrel if ticagrelor or prasugrel are not available or are contraindicated) is recommended for 12 months after PCI, unless there are contraindications such as excessive risk of bleeding 1.
- A P2Y12 inhibitor should also be started promptly, with options including clopidogrel, ticagrelor, or prasugrel, as part of DAPT 1.
- Anticoagulation may be indicated in patients with an indication for oral anticoagulation, in addition to antiplatelet therapy 1.
Considerations
- The use of ticagrelor or prasugrel is not recommended as part of triple antithrombotic therapy with aspirin and oral anticoagulation 1.
- In patients who are at high risk of severe bleeding complications, discontinuation of P2Y12 inhibitor therapy after 6 months should be considered 1.
- In STEMI patients with stent implantation and an indication for oral anticoagulation, triple therapy should be considered for 1–6 months, according to a balance between the estimated risk of recurrent coronary events and bleeding 1.
Quality of Life and Mortality Considerations
- The goal of antithrombotic therapy in STEMI is to reduce the risk of recurrent ischemic events, stent thrombosis, and mortality, while minimizing the risk of bleeding complications 1.
- The choice of antithrombotic regimen should be individualized based on the patient's risk factors, medical history, and potential contraindications 1.
From the FDA Drug Label
Prasugrel tablets are indicated to reduce the rate of thrombotic CV events (including stent thrombosis) in patients with acute coronary syndrome (ACS) who are to be managed with percutaneous coronary intervention (PCI) as follows: Patients with unstable angina (UA) or non-ST-elevation myocardial infarction (NSTEMI) Patients with ST-elevation myocardial infarction (STEMI) when managed with primary or delayed PCI.
Yes, an antithrombotic medication, specifically prasugrel, is used in the management of STEMI. It is indicated to reduce the rate of thrombotic cardiovascular events in patients with acute coronary syndrome, including those with STEMI, who are to be managed with percutaneous coronary intervention (PCI) 2.
From the Research
Antithrombotic Medication in STEMI Management
- Antithrombotic therapy, including antiplatelet and anticoagulant agents, is a crucial component in the management of ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PPCI) 3, 4.
- Dual antiplatelet therapy with aspirin and an oral P2Y12-receptor inhibitor is essential for the acute and long-term treatment of patients with STEMI undergoing PPCI 3, 4, 5.
- Intravenous anticoagulant drugs available for PPCI include unfractionated heparin, low-molecular-weight heparin, and the direct thrombin inhibitor bivalirudin 3, 6.
- Prasugrel and ticagrelor provide a more prompt, potent, and predictable antiplatelet effect compared with clopidogrel, making them the first-line treatment in PPCI 3, 4, 6.
Specific Antithrombotic Agents
- Bivalirudin is the optimized intravenous anticoagulant agent for patients with STEMI undergoing PCI at high risk of bleeding 5.
- Timely and potent ticagrelor and prasugrel with aspirin usage can increase the clinical benefit for patients without increasing the clinical bleeding risk 5.
- Rivaroxaban, a novel oral anticoagulant, has been shown to reduce cardiovascular mortality in patients with ACS, but its use in STEMI management is still being established 6.
Role of Antithrombotic Therapy
- Antithrombotic therapy is essential to optimize clinical outcomes in patients with STEMI undergoing PPCI 3, 4, 5.
- Finding a balance that minimizes both thrombotic and bleeding risk is crucial in the management of STEMI 4, 5.
- Further research is needed to determine the optimal antithrombotic management strategy for patients with STEMI, particularly those at high risk of bleeding 4, 5, 7.
