Patients with HF and reduced LVEF who were re-evaluated after 1 year, had significant improvement in their LVEF and had a more favourable prognosis than HF with preserved and reduced ejection fraction.

Background: Hyperadiponectinemia is an indicator of worse outcomes in advanced heart failure (HF), its role in de novo HF is less clear.Objective: Because this protein is a hormone with starvation properties, we wanted to know its association with nutritional state and its regulator factors in de novo HF.Methods: Adiponectin circulating levels were determined by ELISA at discharge in patients admitted for de novo HF (n=74). Nutritional status was determined by CONUT score. Univariate and multivariate Cox regression analyses were employed to calculate the estimated hazard ratio (HR) with 95% confidence interval (CI) for death or all-cause readmission. Stromal vascular cells (SVC) of EAT and subcutaneous adipose tissue (SAT) from patients (n=5) underwent heart surgery were induced to adipogenesis for 18 days. Then, cells were cultured with complete or starved medium for 8 hours. At the end, adiponectin expression levels were analysed by real time polymerase chain reaction.Results: Patients were grouped regarding nutritional status. There was a strong association between high adiponectin levels and failing nutritional status. Those patients with worse nutritional state had the highest adiponectin and proBNP levels at discharge (p<0.01). Both proteins were slightly correlated (p<0.05). However, only high adiponectin levels were independently associated with death or all-cause readmission. Nutrients starvation upregulated adiponectin expression levels in adipogenesis-induced SVC from EAT or SAT.Conclusions: Worse nutritional state in de novo HF patients is associated with higher adiponectin plasma levels. Their levels were upregulated in adipose cells after being nutrients-starved. These results may help us to understand the adiponectin paradox in HF.

Se presenta un caso de insuficiencia cardíaca refractaria a tratamiento médico en paciente pluripatológico con insuficiencia mitral grave por pseudocleft en el que se decide un manejo intervencionista con implante de MitraClip. Este caso destaca la importancia del manejo multidisciplinar de la insuficiencia cardíaca integrando distintas áreas de la cardiología como la clínica, la imagen avanzada y el intervencionismo percutáneo.
