Key result
The 2024 ESC guidelines introduced a risk factor-weighted clinical likelihood model that tripled the number of individuals classified as having a very low likelihood (≤5%) of obstructive CAD.
The 2024 ESC guidelines introduce a risk factor-weighted clinical likelihood model that significantly improves the ability to rule out obstructive CAD in suspected CCS patients.

May increase safe deferral of testing in suspected CCS; leaves open need for outcome validation before guideline adoption.
Ischaemic Heart DiseaseThe 2024 European Society of Cardiology (ESC) congress introduced key advancements in the management of chronic coronary syndrome (CCS).Updated guidelines incorporated new evidence in the diagnosis and treatment of CCS, and few Late-breaking Clinical Trials dealt with CCS. 1 New Recommendations from 2024 European Society of Cardiology Guidelines Definition and Diagnostic ApproachThe task force provided a more comprehensive definition of CCS, encompassing all clinical conditions characterised by transient, reversible imbalances between myocardial oxygen demand and blood supply, leading to myocardial ischaemia.A four-step, stepwise diagnostic approach is recommended for individuals with suspected CCS.The task force endorses the use of the risk factorweighted clinical likelihood model to estimate the pretest likelihood of obstructive epicardial coronary artery disease (CAD).This scoring system incorporates several variables, including sex, age, angina symptoms and cardiovascular (CV) risk factors, with adjustments based on individual specific features (e.g.peripheral artery disease, resting ECG, echocardiography or vascular calcifications). 2 This tailored approach tripled the number of individuals classified as having a very low likelihood (≤5%) of obstructive CAD, which should defer further diagnostic testing, while enhancing the precision of estimated annualised event rates of MI and mortality.1 What is New from the 2024

Gurgoglione et al. (2024) conducted a review in Chronic coronary syndrome (CCS). 2024 ESC Guidelines was evaluated. The 2024 ESC guidelines introduced a risk factor-weighted clinical likelihood model that tripled the number of individuals classified as having a very low likelihood (≤5%) of obstructive CAD.
