The Effect of Mineralocorticoid Receptor 3 Antagonists on Anti-Inflammatory and Anti-Fatty Acid Transport Profile in Patients with Heart Failure.

Epicardial fat thickness is associated with cardiovascular disease. Mineralocorticoid receptor antagonist (MRA), a pharmaceutical treatment for CVD, was found to have an effect on adipose tissue. Our aim was to analyse the main epicardial fat genesis and inflammation-involved cell markers and their regulation by risk factors and MRA.

Inflammatory and lipid regulation by cholinergic activity in epicardial stromal cells from patients who underwent open-heart surgery.

The modulation of acetylcholine (ACh) release by botulinum toxin injection into epicardial fat diminishes atrial fibrillation (AF) recurrence. These results suggest an interaction between autonomic imbalance and epicardial fat as risk factors of AF. Our aim was to study the inflammatory, lipidic and fibroblastic profile of epicardial stroma from patients who underwent open-heart surgery, their regulation by cholinergic activity and its association with AF.

Cholinergic activity regulates the secretome of epicardial adipose tissue: Association with atrial fibrillation.

Botulinum toxin injection on epicardial fat, which inhibits acetylcholine (ACh) release, reduced the presence of atrial fibrillation (AF) in patients after heart surgery. Thus, we wanted to study the profile of the released proteins of epicardial adipose tissue (EAT) under cholinergic activity (ACh treatment) and their value as AF predictors. Biopsies, explants, or primary cultures were obtained from the EAT of 85 patients that underwent open heart surgery.

Long-term results after concomitant mitral and aortic valve surgery: repair or replacement?

Objectives: The reported superiority of mitral valve (MV) repair for isolated MV regurgitation has not been confirmed in mitroaortic valve surgery. Our goals were to evaluate the feasibility of repair in patients undergoing mitral and aortic valve surgery and to identify factors predisposing to MV replacement, to compare long-term outcomes (survival and MV reoperation) of repair and replacement and to perform a subgroup analysis in patients with rheumatic MV disease.

Methods: From January 1992 through December 2016, 1122 consecutive patients were submitted to concomitant aortic and MV surgery in 2 different centres (Coimbra and Santiago).

The frailty syndrome and mortality among very old patients with symptomatic severe aortic stenosis under different treatments.

Background: The role of frailty as a prognostic factor in non-selected patients with symptomatic severe aortic stenosis (SAS) is still uncertain. This study aims to examine the association between the frailty syndrome and mortality among very old patients with symptomatic SAS, and to assess whether the association varies with the type of SAS treatment.

Methods And Results: Prospective study of 606 patients aged ≥75years with symptomatic SAS, recruited from February 2010 to January 2015, who were followed up through June 2015.

Post-introduction observation of transcatheter aortic valve implantation in Galicia (Spain).

Rationale, Aims And Objectives: Transcatheter aortic valve implantation constitutes an example of a technology introduced into the Galician Health Care System basket and subjected to a post-introduction observational study after coverage. This paper aims to describe the process and results of this experience, illustrating the main challenges and opportunities in using these studies for supporting decision making.

Methods: The study protocol was developed by a multidisciplinary team consisting of experts from the Galician HTA Agency (avalia-t), interventional cardiologists and cardiac surgeons.
