Myocardial structural and functional changes in cardiac amyloidosis: insights from a prospective observational patient registry.

Aims: The pathophysiological hallmark of cardiac amyloidosis (CA) is the deposition of amyloid within the myocardium. Consequently, extracellular volume (ECV) of affected patients increases. However, studies on ECV progression over time are lacking.

Cardiac amyloidosis: a significant blind spot of the H2FPEF score.

Background: Cardiac amyloidosis (CA) often mimics heart failure with preserved ejection fraction (HFpEF). Due to very different treatment strategies, an exact diagnosis and differentiation between pure HFpEF and CA-related heart failure (HF) is important. In the present study, we assessed the recently published H2FPEF score in patients with pure HFpEF, transthyretin (ATTR), as well as light chain (AL) amyloidosis-related HFpEF and tested whether it differentiates between these entities.

Riociguat in pulmonary hypertension and heart failure with preserved ejection fraction: the haemoDYNAMIC trial.

Aims: The presence of pulmonary hypertension (PH) severely aggravates the clinical course of heart failure with preserved ejection fraction (HFpEF). To date, neither established heart failure therapies nor pulmonary vasodilators proved beneficial. This study investigated the efficacy of chronic treatment with the oral soluble guanylate cyclase stimulator riociguat in patients with PH-HFpEF.

Cardiac remodeling in ambitious endurance-trained amateur athletes older than 50 years-an observational study.

Background: Data on cardiac remodeling in veteran athletes are conflicting but of clinical importance.

Methods: Sixty-nine clinically stable and healthy individuals >50 years were identified (median 55 (IQR 52-64), 26% female). Echocardiographic features were identified in individuals, who have performed endurance sports at 70% of their maximum heart rate for at least 1 hour 3 times/ week over the previous 5 years.

Renin Feedback Is an Independent Predictor of Outcome in HFpEF.

Drugs which interact with the renin angiotensin aldosterone system (RAAS) aim to reduce the negative effects of angiotensin (Ang) II. Treatment with these drugs anticipate a compensatory up-regulation of renin; however, it has been shown that there is a large variability in circulating plasma renin (PRA), even in patients with optimal medical therapy in patients with heart failure (HF) with reduced ejection fraction (HFrEF). Our aim was to measure plasma renin activity (PRA-S), its response to RAAS inhibitor (RAASi) therapies and its effects on outcome in patients with HF with preserved ejection fraction (HFpEF).

Prognostic implications of pericardial and pleural effusion in patients with cardiac amyloidosis.

Background: Pericardial and pleural effusion are common findings in patients with cardiac amyloidosis (CA). It is not known, whether effusions correlate with right ventricular (RV) function in these patients. Furthermore, data on the prognostic significance of pleural and pericardial effusion in CA is scarce.

Low serum potassium levels and diabetes - An unfavorable combination in patients with heart failure and preserved ejection fraction.

Background: Heart failure with preserved ejection fraction (HFpEF) is among the most common forms of heart failure (HF). We aimed to investigate the prognostic significance of serum potassium levels and its interaction with type-2 diabetes mellitus in patients with HFpEF.

Methods: Consecutive HFpEF patients were prospectively included in a registry study.

Prognostic implications of psoas muscle area in patients undergoing transcatheter aortic valve implantation.

Objectives: This study sought to assess the incremental prognostic value of the psoas muscle area in patients scheduled for transcatheter aortic valve implantation (TAVI).

Methods: A total of 1076 consecutive patients undergoing TAVI at 2 centres between 2010 and 2017 were prospectively included in this study. Computed tomography-derived cross-sectional area of the psoas muscle was measured at the superior border of the third (L3) and fourth (L4) lumbar vertebra and indexed to body surface area (PMAi) as well as stratified into tertiles.
