Breast arterial calcification: a potential novel imaging marker for HFpEF

Abstract Background Breast arterial calcification (BAC) on mammography has been shown to associate with cardiovascular disease, however the association with heart failure (HF) remains largely uncharacterised. BAC is a medial arterial calcification process, which is a marker of vascular stiffness, a key contributor to diastolic dysfunction (DD) and HFpEF. We sought to evaluate the association between BAC and HFpEF. Purpose This study aims to assess the relationship between BAC status and HFpEF. Methods This retrospective cross-sectional study included 100 consecutive patients with clinically indicated mammography and echocardiography within 6 months of each other. BAC was visually assessed to determine presence or absence. HFpEF was diagnosed based on combined clinical and echocardiographic assessment. DD was defined by Mitter et. al’s(1) criteria after review of echocardiograms. Logistic regression analysis with Odds Ratio (OR) and (95% confidence intervals) are reported for association with any HF, HFpEF, or DD adjusting for modifiable (body mass index, hypertension, hyperlipidaemia, current smoking, diabetes mellitus) and non-modifiable (age, past smoking breast cancer, past ischaemic heart disease (IHD), atrial fibrillation (AF), chronic kidney disease (CKD)) risk factors. Results The prevalence of BAC was 27% and 13% had HFpEF and 55.8% had DD. Patients with BAC were older (mean age 73±13 vs 57±13, p
