Obesity Is Associated with Driveline Infection of Left Ventricular Assist Devices

In patients with left ventricular assist devices (LVADs), the association of driveline infection (DLI) and body mass index (BMI) remains controversial. The aim of this study was to explore a potential correlation between BMI and DLI in the LVAD patient population. A retrospective, single-center study evaluated patients who underwent LVAD implantation between May 2012 and July 2016. Driveline infection was evaluated per Interagency Registry for Mechanically Assisted Circulatory Support established criteria. Of 222 included patients, 80% were male, the average age was 55 years, and the main underlying heart failure diagnosis was nonischemic cardiomyopathy (56%). The majority of patients (65%) received LVAD as destination therapy and 35% as a bridge to transplantation. Average time-to-first DLI was 296 days after LVAD implantation. In comparison to non-DLI group (80%, N = 177), patients in DLI group (20%, N = 45) had a higher BMI (33.5 ± 8.3 kg/m2 in DLI group vs. 28.8 ± 7.5 kg/m2 in non-DLI group, p = 0.0003) and were younger (51 ± 12 years in DLI group vs. 56 ± 12 years in non-DLI group, p = 0.013). There was a significant correlation between BMI and DLI (p

CONCLUSION: ECMO is an important life support method for patients before and after heart transplantation surgery. Obesity, poor preoperative cardiac function, and considerable intraoperative red blood cell transfusion may influence prognosis. Extracardiac compression before ECMO is an independent risk factor for prognosis. PMID: 31410515 [PubMed - as supplied by publisher]

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...

Conclusions Malnutrition is associated with increased mortality and other unfavorable echocardiographic and clinical outcomes compared with those of NB. The same effect of obesity on survival was not observed. Further studies are needed investigating the long-term impact of abnormal anthropometric measurements on outcomes in pediatric DCM.

Abstract Heart failure due to severe obesity is a complex disease due to multiple mechanisms, including increased body mass, inflammation, and impaired cardiac metabolism that is complicated by obesity-associated co-morbidities, such as type 2 diabetes and obstructive sleep apnea. Bariatric surgery significantly improves cardiac geometry, function, and symptoms related to obesity cardiomyopathy. There is a consistently positive impact of bariatric surgery on diastolic function with the potential to significantly improve systolic function as measured by ejection fraction in patients with advanced heart failure. For...

Abstract Heart failure with preserved ejection fraction (HFpEF) is now an emerging cardiovascular epidemic, being identified as the main phenotype observed in clinical practice. It is more associated with female gender, advanced age and comorbidities such as hypertension, diabetes, obesity and chronic kidney disease. Amyloidosis is a clinical disorder characterized by the deposition of aggregates of insoluble fibrils originating from proteins that exhibit anomalous folding. Recently, pictures of senile amyloidosis have been described in patients with HFpEF, demonstrating the need for clinical cardiologists to investigate t...

Authors: Rodriguez Flores M, Aguilar Salinas C, Piché ME, Auclair A, Poirier P Abstract INTRODUCTION: Obesity increases the risk of heart failure (HF), which continues to be a significant proportion of all cardiovascular diseases and affects increasingly younger populations. The cross-talk between adipose and the heart involves insulin resistance, adipokine signaling and inflammation, with the capacity of adipose tissue to mediate hemodynamic signals, promoting progressive cardiomyopathy. Areas covered: From a therapeutic perspective, there is not yet a single obesity-related pathway that when addressed, can...
