Association between CMR-derived hepatic T1-time, tricuspid regurgitation and survival.
Background: Cardiac magnetic resonance (CMR) derived hepatic T1-time is associated with outcome. However, the interplay between tricuspid regurgitation (TR), which can cause congestive hepatopathy and liver T1-time is unclear.
Methods: We measured hepatic T1-time in CMR all-comers, who underwent echocardiography within 3 weeks of CMR. Kaplan-Meier estimates and Cox regression models were used to investigate the association between hepatic T1-time, TR severity and a composite endpoint of heart failure hospitalisation and all-cause death.
Results: 1029 participants (67 ± 17 y/o, 44% female) had a mean hepatic T1-time of 605 ± 79 ms. Overall, 41% (417) presented with non/trace, 38% (391) with mild, 13% (135) with moderate and 8% (85) with severe/massive/torrential TR. Liver T1-time was significantly associated with TR severity (no/trace: 586 ± 72 ms; mild: 601 ± 74 ms; moderate: 634 ± 84 ms; severe/massive/torrential: 665 ± 83 ms; β = 25.4 ms, [95% CI:19.7-31.2, p < .001]). After adjustment for serum NT-proBNP and right ventricular function in a linear regression model, TR severity remained significantly associated with hepatic T1-time (p < .001). During follow-up (mean 53 ± 36 months) 326 (32%) events occurred. Hepatic T1-time (adj.HR 1.69 [95% CI: 1.49-1.92] per 100 ms increase, p < .001) and TR (adj.HR 1.66 [95% CI: 1.49-1.84], p < .001) were both associated with outcome. Even after adjustment for serum NT-proBNP, cardiac structure and function, age, sex and TR severity, hepatic T1-time remained significantly associated with event-free survival (adj.HR 1.42 [95% CI: 1.20-1.68] per 100 ms increase, p < .001).
Conclusion: TR exerts a notable influence on hepatic T1-time. Nevertheless, after adjustment for serum NTproBNP, cardiac function and TR severity, hepatic T1-time still independently predicts outcomes. This underscores the importance of hepatic T1-time both as a marker of TR and prognosis.
期刊介绍：
EJCI considers any original contribution from the most sophisticated basic molecular sciences to applied clinical and translational research and evidence-based medicine across a broad range of subspecialties. The EJCI publishes reports of high-quality research that pertain to the genetic, molecular, cellular, or physiological basis of human biology and disease, as well as research that addresses prevalence, diagnosis, course, treatment, and prevention of disease. We are primarily interested in studies directly pertinent to humans, but submission of robust in vitro and animal work is also encouraged. Interdisciplinary work and research using innovative methods and combinations of laboratory, clinical, and epidemiological methodologies and techniques is of great interest to the journal. Several categories of manuscripts (for detailed description see below) are considered: editorials, original articles (also including randomized clinical trials, systematic reviews and meta-analyses), reviews (narrative reviews), opinion articles (including debates, perspectives and commentaries); and letters to the Editor.
