GLP-1 analog liraglutide-induced cardiac dysfunction due to energetic starvation in heart failure with non-diabetic dilated cardiomyopathy

Glucagon-like peptide-1 (GLP-1) reduces cardiovascular events in diabetic patients; however, its counter-protective effects have also been suggested in patients with heart failure and the clear explanation for...

This study demonstrates for the first time that senescent cells secrete functional LTs, significantly contributing to the LTs pool known to cause or exacerbate idiopathic pulmonary fibrosis. Against Senolytics https://www.fightaging.org/archives/2019/11/against-senolytics/ There is no consensus in science that is so strong as to have no heretics. So here we have an interview with a naysayer on the matter of senolytic treatments, who argues that the loss of senescent cells in aged tissues will cause more harm to long-term health than the damage they will do by remaining. To be clear, I think this to be a ...

Abstract PURPOSE: The present study aimed to investigate the prevalence, characteristics, and clinical significance of concomitant specific cardiomyopathies in subjects with bicuspid aortic valves (BAVs). MATERIALS AND METHODS: A total of 1186 adults with BAV (850 males, mean age 56±14 years) at a single tertiary center were comprehensively reviewed. Left ventricular non-compaction, hypertrophic cardiomyopathy, and idiopathic dilated cardiomyopathy were confirmed when patients fulfilled current clinical and echocardiographic criteria. Clinical and echocardiographic characteristics, including comorbidit...

In conclusion, with study of the frailty syndrome still in its infancy, frailty analysis remains a major challenge. It is a challenge that needs to be overcome in order to shed light on the multiple mechanisms involved in the pathogenesis of this syndrome. Although several mechanisms contribute to frailty, immune system alteration seems to play a central role: this syndrome is characterized by increased levels of pro-inflammatory markers and the resulting pro-inflammatory status can have negative effects on various organs. Future studies should aim to better clarify the immune system alteration in frailty, and seek to esta...

ConclusionsJust under half of patients in this global trial had nonischemic HF with reduced ejection fraction, with idiopathic and hypertensive the most commonly ascribed etiologies. Adjusted outcomes were similar across etiologic categories, as was the benefit of sacubitril/valsartan over enalapril.

Conclusion: Mitofusin 2 promotes Parkin translocation and phosphorylation, leading to mitophagy to clear damaged mitochondria. However, the beneficial effects of MFN2 were reversed by autophagy inhibitors. Additionally, MFN2 participates in mitochondrial fusion to maintain mitochondrial quality. Thus, MFN2 participated in mitophagy and mitochondrial fusion against Ang II-induced cardiomyocyte injury. Introduction Ventricular remodeling is the core foundation for the development of heart failure (Hill and Olson, 2008). Pathological remodeling is typically due to a number of causes that result in increased pressure o...

Discussion Barth syndrome is characterized by a dilated cardiomyopathy, proximal skeletal muscle weakness, neutropenia and short stature that usually presents at birth or soon after. It is a rare X-linked recessive disease process caused by mutations in the TAZ gene. The TAZ gene codes for tafazzin which alters cardiolipin in mitochondria. Characteristic facies can be seen especially in infancy including a tall and broad forehead, prominent chin and full cheeks, larger ears, and deep-set eyes. Most patients present at birth or soon afterwards but some may not until later in life. Life expectancy is reduced with many childr...

Abstract Friedreich's ataxia (FRDA), which occurs in 1/50000 live births, is the most prevalent inherited neuromuscular disorder. Nearly all FRDA patients develop cardiomyopathy at some point in their lives. The clinical manifestations of FRDA include ataxia of the limbs and trunk, dysarthria, diabetes mellitus, and cardiac diseases. However, the broad clinical spectrum makes FRDA difficult to identify. The diagnosis of FRDA is based on the presence of suspicious clinical factors, the use of the Harding criteria and, more recently, the use of genetic testing for identifying the expansion of a triplet nucleotide se...

Conclusion: The findings of the study showed that NGAL associated with NT-proBNP was a stronger predictor of the primary endpoint than NGAL or NT-proBNP alone. The level of NGAL was rising in hypertension, ischemia, anemia, hypoalbuminemia, diabetes or arrhythmias.Kidney Blood Press Res 2018;43:1865 –1877
