From the Guidelines
The management of Acute Coronary Syndrome (ACS) should follow a systematic approach, prioritizing rapid assessment, diagnosis, and immediate interventions to restore blood flow and prevent complications, as outlined in the most recent guidelines 1. The approach to managing ACS can be broken down into several key steps:
- Initial assessment and diagnosis, including electrocardiogram (ECG) and biomarker evaluation
- Immediate interventions, such as administering aspirin, antiplatelet therapy, anticoagulation, and pain control with nitroglycerin and morphine if needed
- Oxygen therapy for patients with oxygen saturation below 90%
- For ST-elevation myocardial infarction (STEMI), immediate reperfusion therapy is crucial, preferably primary percutaneous coronary intervention (PCI) within 90 minutes of first medical contact, or fibrinolytic therapy if PCI is not available within 120 minutes
- For non-ST-elevation ACS (NSTEMI/unstable angina), an early invasive strategy with coronary angiography is recommended for high-risk patients Some key points to consider in the management of ACS include:
- The importance of rapid reperfusion in STEMI patients, as highlighted in the 2020 ESC guidelines 1
- The role of dual antiplatelet therapy, high-intensity statins, beta-blockers, and ACE inhibitors or ARBs in secondary prevention, as outlined in the 2025 ACC/AHA/ACEP/NAEMSP/SCAI guideline 1
- The need for risk factor modification, including smoking cessation, blood pressure and diabetes control, and cardiac rehabilitation, to improve long-term outcomes
- The use of evidence-based guidelines, such as those from the American College of Cardiology and the American Heart Association, to inform management decisions 1 Overall, the management of ACS requires a comprehensive and systematic approach, incorporating the latest evidence-based guidelines and prioritizing rapid assessment, diagnosis, and intervention to improve patient outcomes.

Management Flow of Acute Coronary Syndrome (ACS)
The management flow of ACS can be broken down into several key steps:
- Initial Assessment: Patients presenting with possible ACS should undergo immediate electrocardiography (within 10 minutes of presentation) to distinguish between ST-segment elevation myocardial infarction (STEMI) and non-ST-segment elevation ACS (NSTE-ACS) 2.
- Medical Therapy: Aspirin is recommended for all patients with suspected ACS, unless contraindicated, and a second antiplatelet agent (e.g., clopidogrel, ticagrelor, or prasugrel) should also be added for most patients 3.
- Reperfusion Therapy: For patients with STEMI, rapid reperfusion with primary percutaneous coronary intervention (PCI) within 120 minutes reduces mortality, and if PCI is not possible, fibrinolytic therapy should be administered 2, 3.
- Invasive Coronary Angiography: For high-risk patients with NSTE-ACS, prompt invasive coronary angiography and percutaneous or surgical revascularization within 24 to 48 hours are associated with a reduction in death 2, 4.
- Dual Antiplatelet Therapy (DAPT): DAPT, consisting of aspirin and a P2Y12 inhibitor, reduces cardiovascular event rates after ACS, and the duration of DAPT should be based on patient characteristics, including risk of bleeding and myocardial ischemia 5, 6.
- Other Medical Therapies: Other important management considerations include statin therapy, beta-blocker therapy, sodium-glucose cotransporter-2 inhibitor therapy, and oxygen and nitroglycerin to relieve chest pain 3, 4.
Key Considerations
- Timing of Intervention: The timing of intervention is critical, with rapid reperfusion and invasive coronary angiography associated with improved outcomes 2, 3.
- Risk Stratification: Patients should be risk-stratified to determine the optimal duration of DAPT and the need for invasive coronary angiography 5, 6.
- Bleeding Risk: The risk of bleeding should be carefully considered when selecting antiplatelet therapy and the duration of DAPT 5, 6.
