BackgroundIncreased myocardial triglyceride (TG) content has been recognized as a risk factor for cardiovascular disease. However, its relation with cardiac function in patients on recovery from acute heart failure (HF) remains unclear. In this cross-sectional study, we sought to investigate the association between myocardial TG content measured on magnetic resonance spectroscopy (1H-MRS) and left ventricular (LV) function assessed on cardiovascular magnetic resonance (CMR) in patients who were hospitalized with HF.MethodsA total of 50 patients who were discharged after hospitalization for acute HF and 21 age- and sex-matched controls were included in the study. Myocardial TG content and LV parameters (function and mass) were measured on a 3.0 T MR scanner. Fatty acid (FA) and unsaturated fatty acid (UFA) content was normalized against water (W) using the LC-Model algorithm. The patient population was dichotomized according to the left ventricular ejection fraction (LVEF, <50 % or ≥ 50 %).ResultsH-MRS data were available for 48 patients and 21 controls. Of the 48 patients, 25 had a LVEF <50 % (mean, 31.2 %), whereas the remaining 23 had a normal LVEF (mean, 60.2 %). Myocardial UFA/W ratio was found to differ significantly in patients with low LVEF, normal LVEF, and controls (0.79 % vs. 0.21 % vs. 0.14 %, respectively, p = 0.02). The myocardial UFA/TG ratio was associated with LV mass (r = 0.39, p < 0.001) and modestly related to LV end-diastolic volume (LVEDV; r = 0.24, p = 0.039). We also identified negative correlations of the myocardial FA/TG ratio with both LV mass (r = -0.39, p < 0.001) and LVEDV (r = -0.24, p = 0.039).ConclusionsAs compared with controls, patients who were discharged after hospitalization for acute HF had increased myocardial UFA content; furthermore, UFA was inversely related with LVEF, LV mass and, to a lesser extent, LVEDV. Our study may stimulate further research on the measure of myocardial UFA content by 1H-MRS for outcome prediction.Trial registrationClinicalTrial.gov: NCT02378402.

Background: This prospective study was designed to investigate whether myocardial triglyceride (TG) content from proton magnetic resonance spectroscopy (MRS) and left ventricular (LV) function parameters from cardiovascular magnetic resonance imaging (CMR) can serve as imaging biomarkers in predicting future major cardiovascular adverse events (MACE) and readmission in patients who had been hospitalized for acute heart failure (HF). Methods: Patients who were discharged after hospitalization for acute HF were prospectively enrolled. On a 3.0 T MR scanner, myocardial TG contents were measured using MRS, and LV parameters (function and mass) were evaluated using cine. The occurrence of MACE and the HF-related readmission served as the endpoints. Independent predictors were identified using univariate and multivariable Cox proportional hazard regression analyses. Results: A total of 133 patients (mean age, 52.4 years) were enrolled. The mean duration of follow-up in surviving patients was 775 days. Baseline LV functional parameters—including ejection fraction, LV end-diastolic volume, LV end-diastolic volume index (LVEDVI), and LV end-systolic volume (p < 0.0001 for all), and myocardial mass (p = 0.010)—were significantly associated with MACE. Multivariable analysis revealed that LVEDVI was the independent predictor for MACE, while myocardial mass was the independent predictor for 3- and 12-month readmission. Myocardial TG content (lipid resonances δ 1.6 ppm) was significantly associated with readmission in patients with ischemic heart disease. Conclusions: LVEDVI and myocardial mass are potential imaging biomarkers that independently predict MACE and readmission, respectively, in patients discharged after hospitalization for acute HF. Myocardial TG predicts readmission in patients with a history of ischemic heart disease.

BackgroundSorafenib is an oral tyrosine kinase inhibitor that is indicated for advanced hepatocellular carcinoma (HCC). The aim of the present study was to determine the clinical outcomes of HCC patients receiving sorafenib in real-life clinical setting in comparison with formal clinical trials.MethodsPatients diagnosed with advanced HCC between 2007 and 2015 at single institute were retrospectively enrolled and evaluated for survival and tolerability following sorafenib treatment. Overall survival (OS) and duration of treatment (TTP) were examined by different stratifications including age, gender, etiology, liver functions, and severities.ResultsA total of 67 advanced HCC patients were enrolled for analysis. Of the 67 eligible patients, 66 patients (99%) were diagnosed as Barcelona Clinic Liver Cancer stage C and 45 (67%) were Child-Pugh A. Chronic hepatitis B virus infection was the main etiology (67%), followed by hepatitis C virus infection (12%) and alcohol liver disease (8%). The median duration of treatment was 3.0 months (95% CI 2.6–3.4 months) and median OS was 8.0 months (95% CI 5.0–11.0 months). By multivariate analysis, female gender (HR =2.462, 95% CI 1.126–5.387, P=0.024), Child-Pugh C (HR =3.913, 95% CI 1.063–14.410, P=0.04), extrahepatic spread (HR =2.123, 95% CI 1.122–4.015, P=0.021), and combined other therapies (HR =0.410, 95% CI 0.117–0.949, P=0.037) were the independent predictors of OS.ConclusionOS of advanced HCC patients treated with sorafenib was longer than that reported in the Asia-Pacific trial study. Impaired hepatic functions are associated with the shorter survival in real-life setting.
