- Abstract
Aims The exact role of portal hypertension in cirrhotic cardiomyopathy remains unclear, and it is uncertain whether cardiac abnormalities also occur in non-cirrhotic portal hypertension (NCPH). This magnetic resonance imaging (MRI) study aimed to evaluate the presence of subclinical myocardial dysfunction, oedema, and fibrosis in NCPH. Methods and results In this prospective study (2018–2022), participants underwent multiparametric abdominal and cardiac MRI including assessment of cardiac function, myocardial oedema, late gadolinium enhancement (LGE), and abdominal and cardiac mapping [T1 and T2 relaxation times, extracellular volume fraction (ECV)]. A total of 111 participants were included [44 participants with NCPH (48 ± 15 years; 23 women), 47 cirrhotic controls, and 20 healthy controls]. The cirrhotic group was dichotomized (Child A vs. Child B/C). NCPH participants demonstrated a more hyperdynamic circulation compared with healthy controls (cardiac index: 3.7 ± 0.6 vs. 3.2 ± 0.8 L/min/m², P = 0.004; global longitudinal strain: −27.3 ± 4.6 vs. −24.6 ± 3.5%, P = 0.022). The extent of abnormalities indicating myocardial fibrosis and oedema in NCPH was comparable with Child A cirrhosis (e.g. LGE presence: 32 vs. 33 vs. 69%, P = 0.004; combined T1 and T2 elevations: 46 vs. 27 vs. 69%, P = 0.017; NCPH vs. Child A vs. Child B/C). Correlations between splenic T1 and myocardial T1 values were found (r = 0.41; P = 0.007). Splenic T1 values were associated with the presence of LGE (odds ratio, 1.010; 95% CI: 1.002, 1.019; P = 0.013). Conclusion MRI parameters of myocardial fibrosis and oedema were altered in participants with NCPH to a similar extent as in compensated cirrhosis and were associated with splenic markers of portal hypertension, indicating specific portal hypertensive cardiomyopathy.
