Objective: This study investigates the mechanisms behind exercise capacity in adults with type 2 diabetes mellitus (T2DM), focusing on central and peripheral components, as described by the Fick equation.
Methods: A cross-sectional study of 141 adults with T2DM was conducted, using cardiopulmonary exercise testing, near-infrared spectroscopy (NIRS) and exercise echocardiography. Participants with sufficient-quality NIRS data were stratified into tertiles based on percentage predicted VO₂peak.

Background: Atrial functional mitral regurgitation (AFMR) is prevalent among patients with heart failure with preserved ejection fraction (HFpEF) and associated with adverse outcome, yet this bidirectional association remains underexplored.
Objectives: The purpose of this study was to elucidate the pathophysiological and prognostic significance of AFMR in HFpEF, both at rest and during exercise.
Methods: In this multicenter cohort study, consecutive patients with HFpEF underwent cardiopulmonary exercise testing with echocardiography, with a particular focus on mitral regurgitation (MR) severity assessment in rest and during exercise.

Aims: Obesity is commonly hypothesized to lead to the development of heart failure (HF) in part due to increases in blood volume (BV) and left ventricular (LV) remodelling. Whether adiposity and obesity severity are associated with BV expansion and subsequent LV remodelling in middle-aged individuals at increased risk (IR) prior to the onset of HF is unknown.
Methods And Results: We analysed data from 96 middle-aged (40-64 years) non-obese (25.

Background: Cardiac biomarkers are important components for diagnosing perioperative myocardial infarction (MI). Efforts to detect MI by biomarker-release only faced heavy criticism, because cardiac biomarker-release has also been observed in situations that are not always related to cell death (e.g.

Background: Pulmonary hypertension is associated with cardiovascular events, but when assessed at rest, it has limited sensitivity. Pulmonary vascular reserve can be assessed noninvasively using exercise echocardiography, but this has not been studied in adults with coarctation of aorta (COA). We hypothesized that adults with COA had worse pulmonary vascular reserve compared to controls, and that impaired pulmonary vascular reserve was associated with clinical indices of disease severity independent right ventricular (RV) indices at rest.
