Abstract

BACKGROUND: Liver damage is frequently observed in patients with cardiovascular disease but infrequently quantified. We hypothesized that in patients with cardiovascular disease undergoing cardiac magnetic resonance, liver T1-times indicate liver damage and are associated with cardiovascular outcome.

METHODS: We measured hepatic T1-times, displayed on standard cardiac T1-maps, in an all-comer cardiac magnetic resonance-cohort. At the time of cardiac magnetic resonance, we assessed validated general liver fibrosis scores. Kaplan-Meier estimates and Cox-regression models were used to investigate the association between hepatic T1-times and a composite endpoint of non-fatal myocardial infarction, heart failure hospitalization, and death.

RESULTS: One thousand seventy-five participants (58±18 year old, 47% female) were included (972 patients, 50 controls, 53 participants with transient elastography). Hepatic T1-times were 590±89 ms in patients and 574±45 ms in controls (P=0.052). They were significantly correlated with cardiac size and function, presence of atrial fibrillation, NT-pro-BNP levels, and gamma-glutamyl-transferase levels (P<0.001 for all). During follow-up (58±31 months), a total of 280 (29%) events occurred. On Cox-regression, high hepatic T1-times yielded a significantly higher risk for events (adjusted hazard ratio, 1.66 [95% CI, 1.45-1.89] per 100 ms increase; P<0.001), even when adjusted for age, sex, left and right ventricular ejection fraction, NT-proBNP (N-terminal prohormone of brain natriuretic peptide), and myocardial T1-time. On receiver operating characteristic analysis and restricted cubic splines, we found that a hepatic T1-time exceeding 610 ms was associated with excessive risk.

CONCLUSIONS: Hepatic T1-times on standard cardiac magnetic resonance scans were significantly associated with cardiac size and function, comorbidities, natriuretic peptides, and independently predicted cardiovascular mortality and morbidity. A hepatic T1-time >610 ms seems to indicate excessive risk.
