Abstract

Objectives This study sought to assess the extent and composition of atherosclerosis contributing to acute coronary syndrome events in women compared with men. Background Pathological studies suggest that plaque composition and burden may differ by sex. It is unclear whether sex impacts the extent, characteristics, and potential vulnerability of coronary plaques. Methods A total of 697 patients (24% women) with acute coronary syndromes were enrolled in the prospective, multicenter PROSPECT (Providing Regional Observations to Study Predictors of Events in the Coronary Tree) study. Three-vessel multimodality intracoronary imaging (quantitative coronary angiography, grayscale, and radiofrequency intravascular ultrasound [IVUS]) was performed after treatment of the culprit lesion(s). Events during a median 3.4-year follow-up were ascribed to recurrent culprit versus untreated nonculprit lesions. The authors performed a post hoc, sex-based subgroup analysis. Results Women were older and had more comorbid disease than men. By angiography, women had a similar number of angiographic culprit (p = 0.53) but fewer nonculprit (p = 0.05) lesions, and fewer vessels with nonculprit lesions (p = 0.048) compared with men even after multivariable adjustment (p = 0.002). By IVUS, women had fewer nonculprit lesions (p = 0.002), but similar plaque burden (PB) per lesion (55.6% vs. 55.3%; p = 0.35), and female sex was not predictive of severe (> 70%) PB (p = 0.052). Plaque rupture was less common in women (6.6% vs. 16.3%; p = 0.002) even after adjusting for comorbidities (p = 0.004), as was the total necrotic core volume (p < 0.0001). The frequency of other plaque phenotypes was similar for men and women including pathological intimal thickening, thin-cap fibroatheromas (TCFA), and thick-cap fibroatheromas. Rates of major adverse cardiovascular events attributed to culprit and nonculprit lesions at 1-, 2-, and 3-year follow-up were not significantly different between men and women, although women were rehospitalized more frequently due to culprit lesion-related angina. For men, nonculprit lesion minimal lumen area ≤ 4.0 mm(2), PB ≥70%, and TCFA predicted nonculprit MACE at 3 years, whereas for women, only TCFA and PB were predictive. Conclusions The PROSPECT study validates that despite having more comorbid risk factors than men, women have less extensive coronary artery disease by both angiographic and IVUS measures, and that lesions in women compared with men have less plaque rupture, less necrotic core and calcium, similar plaque burden, and smaller lumens. TCFA may also be a stronger marker of plaque vulnerability in women than men.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
