ESC 2023 ACS guidelines: the '10 commandments' summary (2024)

Who it applies to

Adults presenting with suspected or confirmed acute coronary syndrome, including both ST-elevation and non-ST-elevation presentations, in emergency and cardiology settings.

Key recommendations

• ACS is managed as a single entity along a continuum, with STEMI and NSTE-ACS pathways unified under shared diagnostic and triage principles rather than fully separate guidelines.
• Rapid diagnosis relies on a 0h/1h (or 0h/2h) high-sensitivity troponin algorithm to efficiently rule in or rule out myocardial infarction.
• Primary PCI remains the preferred reperfusion strategy for STEMI when it can be delivered within guideline-recommended time targets from diagnosis.
• In NSTE-ACS, an early invasive strategy is favored for high-risk patients, with timing individualized according to risk rather than a fixed universal cutoff for all patients.
• Complete revascularization is generally preferred over culprit-lesion-only treatment in patients with multivessel disease, including consideration of staged procedures.
• Routine use of a radial-first approach is recommended for coronary angiography and PCI to reduce vascular and bleeding complications.
• Dual antiplatelet therapy duration and intensity should be individualized based on ischemic and bleeding risk, with shortened DAPT courses considered acceptable in selected high-bleeding-risk patients.
• Routine oxygen supplementation is not recommended in patients without hypoxemia.
• Cardiac rehabilitation, structured secondary prevention, and attention to lipid-lowering, blood pressure, and lifestyle measures are emphasized as essential components of post-ACS care.
• Patient-centered communication, shared decision-making, and psychological support are highlighted as integral to comprehensive ACS management, not just the procedural and pharmacological aspects.

What is new in this edition

• Unification of STEMI and NSTE-ACS into a single combined guideline/management framework rather than two separate documents.
• Greater emphasis on individualized, risk-based timing for invasive strategy in NSTE-ACS rather than rigid time-based categories.
• Stronger endorsement of radial access as the default arterial access route.

Practice points for students

• Think of ACS as one spectrum of disease: the same high-sensitivity troponin rule-in/rule-out pathway applies regardless of ECG findings at presentation.
• Reperfusion time targets for STEMI are measured from diagnosis, not just from first medical contact, so rapid ECG acquisition and interpretation matter.
• Not all NSTE-ACS patients need an immediate invasive strategy; risk stratification determines urgency.
• Routine oxygen in ACS without hypoxemia is not indicated and may be harmful.
• Secondary prevention and patient communication are treated as core guideline content, not an afterthought.
