ABSTRACT Aims Metabolic dysfunction-associated steatotic liver disease (MASLD) is associated with heart failure (HF), independent of shared risk factors. Our aim was to describe the incidence of HF in patients with biopsy-proven MASLD. Methods and results We followed patients with biopsy-proven MASLD from the prospective Duke NAFLD Biorepository and Clinical Database from liver biopsy (2007–2013) until death or 5 January 2023. Clinical and echocardiographic data were abstracted via manual chart review. Incident HF was defined as one of the following: (1) hospitalization for HF, (2) medical record diagnosis of HF, (3) ≥1 sign/symptom of HF and elevated natriuretic peptide, or (4) diastolic dysfunction on transthoracic echocardiography with ≥1 sign/symptom of HF. Univariable and multivariable logistic regression models were evaluated. Overall, 570 patients with biopsy-proven MASLD were included. The mean age was 49.5 years, 42.5% were male and 87.0% were non-Hispanic White. Ten patients (1.8%) had baseline HF, leaving 560 patients to assess for incident HF. Over a median follow up of 4009 days (11.0 years) (interquartile range 2270–4672 days), 100 (17.9%) patients developed incident HF while 268 (47.9%) met criteria for HF suspicion. In a multivariable model, increasing age (odds ratio [OR] 1.05, 95% confidence interval [CI] 1.02–1.08, p < 0.001) and female sex (OR 1.85, 95% CI 1.12–3.04, p = 0.02) were associated with incident HF. Conclusions We found a high incidence of HF in patients with biopsy-proven MASLD. Despite nearly half of patients having suspected HF, very few carried a chart diagnosis. Screening for HF in high-risk patients and establishment of formal care pathways to address early HF may reduce morbidity and mortality.

Abstract Aims Left ventricular (LV) subclinical impairment has been described in heart failure with preserved ejection fraction (HFpEF). We assessed the relationship between LV myocardial deformation by strain imaging and recurrent hospitalization for heart failure (HF) or cardiovascular death in a large international HFpEF population. Methods and results We assessed two-dimensional speckle-tracking based global longitudinal strain (GLS) in 790 patients (mean age 74 ± 8 years, 54% female) with adequate image quality enrolled in the PARAGON-HF echocardiography study. We examined the relationship of GLS with total HF hospitalizations and cardiovascular death (the primary composite outcome) after accounting for clinical confounders. Approximately 47% of the population had evidence of LV subclinical dysfunction, defined as absolute GLS <16%. Impaired GLS was significantly associated with higher values of circulating baseline N-terminal pro-B-type-natriuretic peptide. After a median follow-up of 3.0 years, there were 407 total HF hospitalizations and cardiovascular deaths. After multivariable adjustment, worse GLS was associated with a greater risk for the primary composite outcome (adjusted hazard ratio per 1% decrease: 1.06; 95% confidence interval 1.02–1.11; p = 0.008). GLS did not modify the treatment effect of sacubitril/valsartan compared with valsartan for the composite outcome (p for interaction >0.1). Conclusions In a large HFpEF population, impaired LV function was observed even among patients with preserved ejection fraction, and was associated with an increased risk of total HF hospitalizations or cardiovascular death, accounting for clinical confounders. These findings highlight the key role of subtle LV systolic impairment in the pathophysiology of HFpEF.
