Management of chronic coronary syndrome

Published on 26 March 2025

This ACE Clinical Guideline (ACG) provides evidence-based recommendations for managing patients with chronic coronary syndrome (CCS), with a focus on antiplatelet therapy and non-pharmacological interventions, including physical activity, smoking cessation, and dietary advice. Additionally, principles for assessing patients with CCS presenting with acute exacerbation of chest pain are outlined.

The ACG includes links to two patient education aids on coronary heart disease (CHD), and myths and facts about antiplatelet medicines for chronic CHD.

ACG recommendations

1a.Use long-term low-dose aspirin monotherapy for secondary prevention of cardiovascular events.

1b.Consider long-term clopidogrel monotherapy as an alternative to aspirin.

2.Review patients following PCI to confirm that there is a specified treatment duration for their dual antiplatelet therapy and check with the referring cardiologist if treatment duration is unclear.

3a.For patients with new-onset AF with no recent stent (within the past 12 months), consider oral anticoagulant monotherapy based on modified CHA₂DS₂VASc score and patient factors such as comorbidities and bleeding risk. 

3b.For patients with new-onset AF and a stent within the past 12 months, consult a cardiologist to reassess and optimise the current antithrombotic therapy.

4.Optimise management of comorbid or associated conditions in patients with CCS to reduce overall cardiovascular risk and complications.

5.Encourage sustained lifestyle interventions, including regular physical activity tailored to the patient’s capabilities and preferences.

6.Schedule regular follow-up visits for all patients with CCS to monitor symptoms, assess medication adherence, and adjust treatment plans as needed.
