Abstract 11711: Quantification of Atherosclerotic Coronary Artery Disease in the Pre/Peri-Menopausal Female Using Cardiac CTA

Abstract

Introduction: Coronary Artery Disease (CAD) occurs equally in males and females and is the most common cause of death in both genders worldwide. The pre/peri-menopausal female is believed to have minimal coronary atherosclerosis based primarily on non-invasive techniques, with limited coronary angiography data. Cardiac computed tomography angiography (CCTA) is a more sensitive, non-invasive anatomical diagnostic tool for quantifying coronary atherosclerosis, but pre/peri-menopausal women have been underrepresented and underdiagnosed. The goal of this study was to quantify coronary atherosclerosis in this population. Methods: We conducted a retrospective chart review on 510 females aged 35-60 presenting with atypical chest pain and shortness of breath. These were consecutive admissions in which CCTA was performed from January 2014 to December 2019. The degree of coronary atherosclerosis was quantified using the CAD-RADS scoring system. Results: Analysis showed 68.82% of patients had no evidence of coronary atherosclerosis. 4.31% had minimal CAD, 18.24% had mild CAD, 6.47% had moderate CAD and 2.16% were found to have severe CAD. Each category of stenosis typically had multiple vessels involved. Over 65% of patients were Non-Hispanic White, 27% Hispanic, 8% African American and 4% Asian. Less than 5% of patients were discharged with statin therapy. Conclusions: This is the first study to quantify coronary atherosclerosis in the pre/peri-menopausal female. Quantification was based on coronary angiograms obtained by CCTA, currently the most sensitive diagnostic imaging technique. Despite the perceived protective nature of the premenopausal state in women, 30% of patients had detectable CAD by CCTA. 10% had greater than 50% stenosis (moderate to severe CAD), suggesting the potential for future ischemic heart disease. So few patients were discharged on statin therapy, showing the paucity of guideline therapy used in this population. These results suggest targeting preventative therapy, even late in the pre or peri-menopausal stage, such as favorable lifestyle changes and reducing known modifiable cardiac risk factors, should significantly prevent the progression of coronary atherosclerosis and its subsequent sequelae in menopause.
