Women develop coronary atherosclerosis and experience ACS later in life compared with men [1-3]. It remains unclear whether coronary plaque development has a later onset in women, whether the magnitudes of risk are similar between sexes and whether treatment should be different in women vs. men. Atherosclerotic assessment with coronary computed tomography angiography (CCTA) can be used to determine the ‘atherosclerotic plaque burden’, and determine intensity of treatment.

Aim of the study

The authors examined sex- and age-specific interaction in atherosclerotic onset and risk for MACE in stable patients undergoing a CCTA.



In this study, 24950 patients from the CONFIRM (COronary CT Angiography EvaluatioN For Clinical Outcomes: an InteRnational Multicenter) registry were included. The CONFIRM registry consisted of a large, multi-center, international, observational cohort, of which prospectivelydata were collected from patients who underwent clinically indicated CCTA [4]. In this study, patients with known CAD were excluded. The Leiden CCTA score, which integrates coronary plaque presence, extent, severity, composition and location into a single score, was calculated. A total of 11678 women and 13272 men were followed for a median period of 3.7 years.


The primary outcome was the difference in CCTA score between women and men for similar age. Secondary outcomes were differences in MACE, defined as all-cause mortality and MI.

Main results

Leiden CCTA risk score

CAD and atherosclerotic plaque characteristics


In this large registry with patients undergoing a CCTA, coronary atherosclerosis developed 12 years later in women compared with men. A lower Leiden CCTA score was detected in women vs. men across all age categories. The Leiden CCTA score was associated with MACE in both sexes, but the risk for all-cause mortality and MI was higher in post-menopausal women with a Leiden CCTA score >20 compared with men. “[This] may have therapeutic implications for initiation of the most intensive preventive medical therapies even in the absence of prior coronary events [in this patient group]”, said the authors.
