Background. Heart failure with preserved ejection fraction (HFpEF) has a complex pathophysiology that encompasses systemic proinflammatory state and dysregulated levels of cardiometabolic and oxidative stress biomarkers. The prevalence of both HFpEF and atrial fibrillation (AF) is continuously rising, especially in the elderly. The aim of our study was to explore if there were any differences in biomarker levels and vascular function in the elderly patients with HFpEF with and without AF and to assess interconnections between clinically relevant biomarkers and cardiac and vascular function. Methods. This was a cross-sectional study of years with HFpEF who were divided into 2 groups based on the presence or absence of AF. We have sonographically assessed echocardiographic parameters of left ventricular systolic and diastolic function and the peripheral vascular function parameters, namely, pulse wave velocity (PWV) and flow-mediated dilation (FMD). NT-proBNP, irisin, leptin, adiponectin, insulin-like growth factor 1 (IGF-1), and malondialdehyde (MDA) blood levels were determined. Results. Fifty-two patients (mean age years, 67% females) were included. Patients with HFpEF and AF had significantly lower levels of irisin (median 4.75 vs. 13.5 ng/mL, ), leptin (median 9.5 vs. 15.0 ng/L, ), and MDA (median 293 vs. 450 ng/mL, ) and significantly higher values of NT-proBNP (median 2365 vs. 529 ng/L, ) but not vascular function parameters, as compared to HFpEF patients without AF. MDA was significantly correlated with diastolic function ( , ) and FMD ( , ), while adiponectin was inversely associated with FMD ( , ) and left ventricular ejection fraction (
(1) Background: Aquatic exercise training is a relatively understudied exercise modality in patients with CAD; with the present study, we sought to compare the impact of short-term 14-day water- and land-based exercise training on heart rate variability (HRV). (2) Methods: We randomized 90 patients after a recent CAD event (myocardial infarction and/or revascularization within 2 months prior to inclusion) to either (i) water-based or (ii) land-based exercise training (14 days, two 30 min sessions daily), or (iii) controls. Before and after the intervention period, all participants underwent 20 min 12-channel high-resolution ECG recordings with off-line HRV analysis, including conventional linear time- and frequency-domain analysis (using the Welch method for fast-Fourier transformation), and preselected non-linear analysis (Poincaré plot-derived parameters, sample entropy, and the short-term scaling exponent α1 obtained by detrended fluctuation analysis). (3) Results: Eighty-nine patients completed the study (mean age 60 ± 8 years; 20 % women). We did not detect significant differences in baseline- or age-adjusted end-of-study HRV parameters, but aquatic exercise training was associated with a significant increase in the linear LF/HF parameter (from 2.6 [1.2–4.0] to 3.0 [2.1–5.5], p = 0.046) and the non-linear α1 parameter (from 1.2 [1.1–1.4] to 1.3 [1.2–1.5], p = 0.043). (4) Conclusions: Our results have shown that a short-term 14-day aquatic exercise training program improves selected HRV parameters, suggesting this mode of exercise is safe and may be beneficial in patients with CAD.
Summary: The new guidelines for the management of peripheral arterial and aortic diseases (PAAD) from the European Society of Cardiology and endorsed by the European Society of Vascular Medicine (ESVM), emphasize on a comprehensive and multidisciplinary approach focusing on prevention, diagnosis, treatment, and follow-up of patients with a wide range of PAAD, including lower extremity peripheral arterial disease (PAD). The aim of this summary, focusing on PAD and coordinated by the Young Academy of ESVM, is to provide young angiologists with the fundamental principles of these guidelines and to assist them in navigating their everyday clinical practice. PAD diagnosis relies on objective evaluation of flow/oxygen reduction at rest, with arterial ultrasound as the first imaging modality to confirm the presence of arterial lesions. The main goals of PAD management are not only to improve functioning and prevent the occurrence of adverse events at the lower limb level, but also to reduce the overall atherosclerotic burden and achieve the general well-being of patients. To this end, traditional and nontraditional cardiovascular risk factors need to be properly addressed through lifestyle changes and tailored drug therapies. For patients with exertional limb symptoms, supervised exercise training is recommended. Interventional treatment is indicated for limb salvage in patients with chronic limb threatening ischemia and may also be discussed in a multidisciplinary setting in less severe patients with persisting symptoms and reduced quality of life after a minimum period of optimal medical treatment including exercise therapy. For trainees or young specialists in Angiology/Vascular Medicine, these guidelines provide essential elements to improve patient management, encourage interdisciplinary collaboration, and ensure an integrated approach to vascular diseases.

Despite potent antiretroviral therapy, HIV still causes brain damage. Better penetration into the CNS and efficient elimination of monocyte/macrophages reservoirs are two main characteristics of an antiretroviral drug that could prevent brain damage. The aim of our study was to assess efficacy of three antiretroviral drug scores to predict brain atrophy in HIV-infected patients. A cross sectional study consisting of 56 HIV-infected patients with controlled viremia, who had no clinically evident neurocognitive impairment. All patients had MRI of the head. A typical T2 transversal slice was analyzed and ventricles-brain ratio (VBr) as an overall brain atrophy index was calculated. Three antiretroviral drug scores were used and correlated with VBr: 2008 and 2010 CNS penetration effectiveness scores (ΣCPE2008 and ΣCPE2010) and the recently established monocyte efficacy (ΣME) score. A p-value <0.05 was considered significant. ΣCPE2010 was significantly associated with VBr in both univariate (r=-0.285, p=0.033) and multivariate (β=-0.299, p=0.016) regression models, while ΣCPE2008 was not (r=-0.141, p=0.300 and β=-0.156, p=0.214). ΣME was associated with VBr in multivariate model only (r=-0.297, p=0.111 and β=-0.406, p=0.029). Age and reported duration of HIV infection were also significant predictors of overall brain atrophy in multivariate regression models. Although based on similar type of research, ΣCPE2010 is a superior drug score compared to ΣCPE2008. ΣME is an efficient drug score in determining brain damage. Both ΣCPE2010 and ΣME scores should be taken into account in preventive strategies of brain atrophy and neurocognitive impairment in HIV-infected patients.
