Abstract Background Chronic heart failure (CHF) is one of the most common causes of mortality in industrialized countries despite regular therapeutic advances. Numerous factors influence mortality in CHF patients, including nutritional status. It is known that malnutrition is a risk factor for mortality, whereas obesity may play a protective role, a phenomenon dubbed the “obesity paradox”. However, the effect of the obesity-malnutrition association on mortality has not been previously studied for CHF. Our aim was to study the effect of nutritional status on overall mortality in CHF patients. Methods This retrospective, multicenter study was based on a French nationwide database (PMSI). We included all CHF patients aged ≥18 years admitted to all public and private hospitals between 2012 and 2016 and performed a survival analysis over 1 to 4 years of follow-up. Results Malnutrition led to a significant decrease in life expectancy in CHF patients when compared with normal nutritional status (aHR=1.16 [1.14-1.18] at one year and aHR=1.04 [1.004-1.08] at four years), obese, and obese-malnutrition groups. In contrast, obesity led to a significant increase in life expectancy compared with normal nutritional status (aHR=0.75 [0.73-0.78] at one year and aHR=0.85 [0.81-0.90] at four years), malnutrition, and obese-malnutrition groups. The mortality rate was similar in patients presenting both malnutrition and obesity and patients with normal nutritional status. Conclusions Our results indicate that the protective effect on mortality observed in obese CHF patients seems to be linked to fat massincrease. Furthermore, malnourished obese and normal nutritional status patients had similar mortality rates. Further studies should be conducted to confirm our results and to explore the physiopathological mechanisms behind these effects.

Cardiac pathologies are among the leading causes of mortality and morbidity in industrialized countries, with myocardial infarction (MI) representing one of the major conditions leading to heart failure (HF). Hitherto, the development of consistent, stable, and reproducible models of closed-chest MI in large animals, meeting the clinical realism of a patient with HF subsequent to chronic ischemic necrosis, has not been successful. We hereby report the design and ensuing application of a novel porcine experimental model of closed-chest chronic ischemia suitable for biomedical research, mimicking post-MI HF. We also emphasize the key procedural steps involved in replicating this unprecedented model, from femoral artery and vein catheterization to MI induction by permanent occlusion of the left anterior descending coronary artery through superselective deployment of platinum-nylon coils, as well as endomyocardial biopsy sampling for histologic analysis and cell harvesting. Our model could indeed represent a valuable contribution and tool for translational research, providing precious insights to understand and overcome the many hurdles concerning, and currently quenching, the preclinical steps mandatory for the clinical translation of new cardiovascular technologies for personalized HF treatments.

AbstractOn December 3rd, 2020, the cumulative number of U.S. Covid-19 deaths tallied by Johns Hopkins University (JHU) online dashboard reached 275,000, surpassing the number at which life table calculations show Covid-19 mortality will lower the U.S. life expectancy at birth (LEB) for 2020 by one full year. Such an impact on the U.S. LEB is unprecedented since the end of World War II. With additional deaths by the year end, the reduction in 2020 LEB induced by Covid-19 deaths will inexorably exceed one year. Factoring the expected continuation of secular gains against other causes of mortality, the U.S. LEB should still drop by more than a full year between 2019 and 2020. By comparison, the opioid-overdose crisis led to a decline in U.S. LEB averaging .1 year annually, from 78.9 years in 2014 to 78.6 years in 2017. At its peak, the HIV epidemic reduced the U.S. LEB by .3 year in a single year, from 75.8 years in 1992 to 75.5 years in 1993. As of now, the US LEB is expected to fall back to the level it first reached in 2010. In other words, the impact of Covid-19 on U.S. mortality can be expected to cancel a decade of gains against all other causes of mortality combined.

Abstract Background Mitral regurgitation (MR) is the most common heart valve disorder worldwide. The contrast between the large burden of MR and the overall low number of performed mitral valve surgery suggest a marked undertreatment of MR patients. Large and comprehensive contemporary data assessing the management and outcome of patients with MR as well as the societal burden of the disease at the Nationwide level are currently lacking. Methods Based on a French mandatory administrative hospital-discharge database, we collected all admissions in France both in public and private hospitals in 2014 and 2015 with MR as primary or secondary code. Patients with infective endocarditis, congenital or rheumatic disease were excluded. Cost were calculated for patients admitted in public hospitals. Results In 2014–2015, 107,412 patients with MR were admitted in France in 1238 public and private hospitals; 74,098 patients (69%) presented with primary MR (PMR) and 33,314 patients (31%) with secondary MR (SMR). Overall 8,676 patients (8%) were operated on (81% PMR) within 1 year and 98,736 (92%) were conservatively managed and constituted our study population. Mean age was 77±15 years (50% were ≥80 years and 12% ≥90 years) and 53% were female. Most of the patients presented with comorbidities and Charlson Index was ≥2 in 53% of the population. In-hospital and one-year mortality were 4.1% and 14.3% respectively. Readmission were very common and one-year mortality/readmission all cause, and one-year mortality / CHF readmission rates were 67% and 34% respectively and increased with age, Charlson Index, CHF at presentation and SMR etiology but events rate remained notably high in the PMR subset (64% and 28% respectively). The total annual cost in public hospitals (initial hospitalisation and readmissions) was 325,716,311 euros. When only readmissions for heart failure were considered (43% of all readmissions), total annual cost was 202,904,869 euros. Conclusion In this large administrative contemporary nationwide database, 1) MR was a common reason for admission and affected an elderly population with frequent comorbidities, 2) less than 10% of patients were offered any intervention, 3) MR was associated with high mortality and readmissions rates in all subsets; 4) MR represented a major societal burden with an extrapolated annual cost between 250 and 400 million euros. These finding highlight the critical need to develop strategies to improve the overall management and outcomes of patients with both primary and secondary MR.

The Difference

Abstract Although the US has one of the highest per-capita health expenditures in the world, it noticeably lags behind a number of other industrialized countries in terms of life expectancy (LE). These disparities remain unexplained by individual demographic, socioeconomic, and healthcare factors. Analysis of death certificates for 1999-2016 revealed that diseases contributed most to LE variability are myocardial infarction (explained 12.9% of the difference in mortality), heart failure (10.6%), stroke (8.2%), lung cancer (7.5%) and COPD (7.2%). Analysis of histories of diseased patients in Medicare records showed that septicemia (15.7%), low weight (13.8%), renal disease (13.3%), disorders of electrolyte and fluid balance (9.0%) and heart failure (7.3%) contributed most to the disparities. Diseases that substantially contribute to disparities in LE in the US include both common and less-often-discussed diseases. Future studies of variations in treatment patterns, access-to and quality-of medical care for these diseases could provide important insight in observed patterns.

Abstract Recently, we have read with great interest the article published by Ibarrola et al. (Clin. Sci. (Lond.) (2018) 132, 1471–1485), which used proteomics and immunodetection methods to show that Galectin-3 (Gal-3) down-regulated the antioxidant peroxiredoxin-4 (Prx-4) in cardiac fibroblasts. Authors concluded that ‘antioxidant activity of Prx-4 had been identified as a protein down-regulated by Gal-3. Moreover, Gal-3 induced a decrease in total antioxidant capacity which resulted in a consequent increase in peroxide levels and oxidative stress markers in cardiac fibroblasts.’ We would like to point out some results stated in the article that need further investigation and more detailed discussion to clarify certain factors involved in the protective role of Prx-4 in heart failure.
