Abstract
- • Among 762 patients with LDL-C≥190 mg/dL without a history of ASCVD or heart failure, coronary artery calcification (CAC), and thoracic aortic calcification (TAC) scores were associated with increased rates of HF hospitalizations. However, only CAC demonstrated an independent association with HF hospitalizations. • EAT, and NAFLD are known cardiometabolic risk factors but were not associated with increased HF hospitalizations in this cohort. • Adding ordinal CAC score to traditional risk factors improved risk stratification for HF hospitalizations. • Given the number of non-cardiac chest CT scans performed in clinical practice, this could represent an opportunity to capitalize on risk information. Coronary artery calcium (CAC), thoracic aorta calcification (TAC), non-alcoholic fatty liver disease (NAFLD), and epicardial adipose tissue (EAT) are associated with atherosclerotic cardiovascular disease (ASCVD) and heart failure (HF). We aimed to determine whether these cardiometabolic and atherosclerotic risk factors identified by non-contrast chest computed tomography (CT) are associated with HF hospitalizations in patients with LDL-C≥ 190 mg/dL. We conducted a retrospective cohort analysis of patients with LDL-C ≥190 mg/dL, aged ≥40 years without established ASCVD or HF, who had a non-contrast chest CT within 3 years of LDL-C measurement. Ordinal CAC, ordinal TAC, EAT, and NAFLD were measured. Kaplan-Meier curves and multivariable Cox regression models were built to ascertain the association with HF hospitalization. We included 762 patients with median age 60 (53–68) years, 68% (n=520) female, and median LDL-C level of 203 (194–216) mg/dL. Patients were followed for 4.7 (interquartile range 2.75–6.16) years, and 107 (14%) had a HF hospitalization. Overall, 355 (47%) patients had CAC=0, 210 (28%) had TAC=0, 116 (15%) had NAFLD, and median EAT was 79 mL (49-114). Moderate-Severe CAC (log-rank p <0.001) and TAC (log-rank p=0.006) groups were associated with increased HF hospitalizations. This association persisted when considering myocardial infarction (MI) as a competing risk. NAFLD and EAT volume were not associated with HF. In patients without established ASCVD and LDL-C≥190 mg/dL, CAC was independently associated with increased HF hospitalizations while TAC, NAFLD, and EAT were not. Association of cardiometabolic and atherosclerotic markers on non-contrast Chest CT with Heart Failure Hospitalization in Patients with Severe Hypercholesterolemia. * Unadjusted Hazard Ratio for the moderate-to-severe category. ASCVD: atherosclerotic cardiovascular disease, CAC: coronary artery calcification. HF: heart failure, LDL-C: low-density lipoprotein cholesterol, NAFLD: non-alcoholic fatty liver disease, TAC: thoracic aorta calcification. [Display omitted] [ABSTRACT FROM AUTHOR]
