188 - The Clot Thickens: Key Updates from the 2025 Acute Coronary Syndromes Guidelines

In this episode, we review the new 2025 ACC/AHA Acute Coronary Syndrome (ACS) guidelines, with a particular focus on guideline recommendations for analgesics, P2Y12 inhibitors, parenteral anticoagulation, and lipid management.

Key Concepts

1. Nitrates and opioids are recommended for symptomatic relief of chest pain. Some patients may not be appropriate for nitrates (e.g. recent PDE-5 inhibitor use, hypotension, or right ventricular infarction). Opioids are used for nitrate-refractory angina but have a theoretical risk of delaying the effect of oral antiplatelet medications.
2. Prasugrel and ticagrelor are preferred P2Y12 inhibitors over clopidogrel in most patients. Patient-specific factors, including the use of PCI, play a role in P2Y12 inhibitor selection.
3. Anticoagulation with heparin is recommended in nearly all acute coronary syndrome (ACS) scenarios. Alternative anticoagulants may be used depending on whether PCI/CABG is planned and whether the anticoagulant is used prior to PCI/CABG (“upstream”) or during the PCI procedure itself.
4. LDL goals after ACS have changed again. All ACS patients should have an LDL goal < 70 with a consideration of an LDL goal of 55-69. A variety of non-statin therapies may be added to a high intensity statin regimen if LDL is not at goal.
