Concomitant Hepatorenal Dysfunction and Malnutrition in Valvular Heart Surgery: Long-Term Prognostic Implications for Death and Heart Failure.

ABSTRACT: Background Strategies to improve long-term prediction of heart failure and death in valvular surgery are urgently needed because of an increasing number of procedures globally. This study sought to report the prevalence, changes, and prognostic implications of concomitant hepatorenal dysfunction and malnutrition in valvular surgery. Methods and Results In 909 patients undergoing valvular surgery, 3 groups were defined based on hepatorenal function (the modified model for end-stage liver disease excluding international normalized ratio score) and nutritional status (Controlling Nutritional Status score): normal hepatorenal function and nutrition (normal), hepatorenal dysfunction or malnutrition alone (mild), and concomitant hepatorenal dysfunction and malnutrition (severe). Overall, 32%, 46%, and 19% of patients were classified into normal, mild, and severe groups, respectively. Over a 4.1-year median follow-up, mild and severe groups incurred a higher risk of mortality (hazard ratio [HR], 3.17 [95% CI, 1.40-7.17] and HR, 9.30 [95% CI, 4.09-21.16], respectively), cardiovascular death (subdistribution HR, 3.29 [95% CI, 1.14-9.52] and subdistribution HR, 9.29 [95% CI, 3.09-27.99]), heart failure hospitalization (subdistribution HR, 2.11 [95% CI, 1.25-3.55] and subdistribution HR, 3.55 [95% CI, 2.04-6.16]), and adverse outcomes (HR, 2.11 [95% CI, 1.25-3.55] and HR, 3.55 [95% CI, 2.04-6.16]). Modified model for end-stage liver disease excluding international normalized ratio and controlling nutritional status scores improved the predictive ability of European System for Cardiac Operative Risk Evaluation (area under the curve: 0.80 versus 0.73, P<0.001) and Society of Thoracic Surgeons score (area under the curve: 0.79 versus 0.72, P=0.004) for all-cause mortality. One year following surgery (n=707), patients with persistent concomitant hepatorenal dysfunction and malnutrition (severe) experienced worse outcomes than those without. Conclusions Concomitant hepatorenal dysfunction and malnutrition was frequent and strongly linked to heart failure and mortality in valvular surgery.

Project description:AimsThis study aimed to evaluate the prognostic significance of nutritional status in post-discharge Asians with heart failure with preserved ejection fraction (HFpEF).Methods and resultsWe examined the prognostic implications of body mass index (BMI) and nutritional markers among consecutive patients hospitalized for HFpEF. Nutritional metrics were estimated by serum albumin (SA), prognostic nutritional index (PNI), Controlling Nutritional Status (CONUT) score, and geriatric nutritional risk index. Among 1120 patients (mean age: 77.2 ± 12.6 years, 39.4% men), mean SA levels, PNI, CONUT scores, and geriatric nutritional risk index were 3.3 ± 0.6 g/dL, 40.2 ± 8.7, 5.5 ± 2.1, and 95.9 ± 14.5, respectively. Lean body size, higher white blood cell counts and C-reactive protein levels, anaemia, and lack of angiotensin blocker use were independently associated with malnutrition (defined by SA < 3.5 g/dL). Higher SA levels [hazard ratio (HR): 0.67 (95% confidence interval, CI: 0.53-0.85)], higher PNI [HR: 0.97 (95% CI: 0.95-0.99)], and higher geriatric nutritional risk index [HR: 0.98 (95% CI: 0.97-0.99)] (all P < 0.05) were all associated with longer survival, with higher CONUT score [HR: 1.08 (95% CI: 1.02-1.13)] exhibited higher mortality in Cox regression models and with higher SA levels/PNI but not BMI further contributing to the reduced rate of re-hospitalization (both P < 0.05). Categorizing BMI (25 kg/m2 as cut-off) and nutritional status showed significantly higher mortality rates among patients with lower BMI/malnutrition than among those with BMI/better nutrition (SA level, PNI, and CONUT score, all P < 0.01). Restricted cubic spline regression revealed a marked survival benefit of better nutrition with increasing BMI (adjusted Pinteraction for both SA level and PNI: <0.001; adjusted Pinteraction for CONUT score: 0.046).ConclusionsMalnutrition was frequently and strongly associated with systemic inflammation in Asian patients hospitalized for acute HFpEF. Our findings also indicate that nutrition may play a pivotal role in metabolic protection in this population.

Project description:IntroductionUltrasonography is widely used as the first tool to evaluate fatty liver disease, and the hepatorenal index is a semi-quantitative method that improves its performance. Fibrosis can co-exist with steatosis or even replace it during disease progression. This study aimed to evaluate the influence of fibrosis on the measurement of steatosis using the hepatorenal index.Materials and methodsThis cross-sectional study included 89 patients with nonalcoholic fatty liver disease and in whom liver fibrosis was determined by ultrasound elastography. The Pearson's correlation coefficient was used to compare between the results of the sonographic hepatorenal index and the quantification of steatosis using magnetic resonance spectroscopy as well the accuracy of detecting moderate to severe steatosis using sonography in two groups of patients: (A) without advanced fibrosis and (B) with advanced fibrosis. Advanced fibrosis was defined as a shear wave speed ≥ 1.78 m/s on ultrasound elastography. We calculated the area under the curve (AUC-ROC) to detect the ability of the hepatorenal index to differentiate light from moderate to severe steatosis in both groups. Moderate to severe steatosis was defined as a fat fraction > 15% on the magnetic resonance spectroscopy. The intra-observer variability was assessed using the Bland-Altman plot.ResultsAmong patients, the mean age was 54.6 years and 59.6% were women, 50.6% had a body mass index ≥ 30 kg/m2, 29.2% had moderate to severe steatosis, and 27.2% had advanced fibrosis. There was a correlation between steatosis grading by ultrasonography and magnetic resonance in group A (0.73; P < 0.001), but not in Group B (0.33; P = 0.058). The AUC-ROC for detecting a steatosis fraction ≥ 15% was 0.90 and 0.74 in group A and group B, respectively. The intra-observer variability for the hepatorenal index measurements was not significant (-0.036; P = 0.242).ConclusionThe hepatorenal index is not appropriate for estimating steatosis in livers with advanced fibrosis.

Project description:BackgroundCancer survivors face elevated risks of heart failure (HF) and death, with cardiac dysfunction being a significant concern. Current evaluations often emphasize systolic function while insufficiently addressing diastolic function. This study aims to investigate the prevalence of diastolic dysfunction and assess its prognostic implications in long-term cancer survivors.MethodsWe analyzed participants from the Atherosclerosis Risk in Communities (ARIC) Study with complete echocardiographic assessments and documented cancer histories. Diastolic function was classified by guideline criteria: normal (≤ 1 abnormal parameter), indeterminate (2 abnormal parameters), and dysfunction (≥ 3 abnormal parameters). The primary outcomes were incident HF and all-cause death. Diastolic dysfunction prevalence was compared between cancer survivors and non-cancer participants after propensity score matching. Cox regression, Kaplan-Meier, and restricted cubic spline (RCS) analyses were used to assess associated risks.ResultsA total of 5322 participants were included, with 18.4% (N = 979) being cancer survivors. The mean age of cancer survivors at echocardiography was 76.3 (5.10) years, with a median of 12.17 years since diagnosis. There were no significant differences in diastolic dysfunction prevalence (12.26% vs 10.73%, P = 0.29) after matching. Cox regression revealed a graded association between diastolic dysfunction and risks of HF and death. Fully adjusted hazard ratios were 2.59 (95% CI: 1.59-4.20, P < 0.001) for indeterminate diastolic function and 4.41 (95% CI: 2.40-8.12, P < 0.001) for diastolic dysfunction in HF; and 1.68 (95% CI: 1.26-2.25, P < 0.001) for indeterminate and 2.21 (95% CI: 1.51-3.22, P < 0.001) for diastolic dysfunction in all-cause death. These results were consistent across subgroup and sensitivity analyses and supported by Kaplan-Meier curves. RCS analyses demonstrated dose-response relationships between individual diastolic parameters and outcomes.ConclusionsDiastolic dysfunction is prevalent among long-term cancer survivors and is stepwise associated with adverse outcomes. These findings underscore the essential need for ongoing monitoring of diastolic function in this population.
