Microvascular and lymphatic dysfunction in HFpEF and its associated comorbidities

AbstractHeart failure with preserved ejection fraction (HFpEF) is a complex heterogeneous disease for which our pathophysiological understanding is still limited and specific prevention and treatment strategies are lacking. HFpEF is characterised by diastolic dysfunction and cardiac remodelling (fibrosis, inflammation, and hypertrophy). Recently, microvascular dysfunction and chronic low-grade inflammation have been proposed to participate in HFpEF development. Furthermore, several recent studies demonstrated the occurrence of generalized lymphatic dysfunction in experimental models of risk factors for HFpEF, including obesity, hypercholesterolaemia, type 2 diabetes mellitus (T2DM), hypertension, and aging. Here, we review the evidence for a combined role of coronary (micro)vascular dysfunction and lymphatic vessel alterations in mediating key pathological steps in HFpEF, including reduced cardiac perfusion, chronic low-grade inflammation, and myocardial oedema, and their impact on cardiac metabolic alterations (oxygen and nutrient supply/demand imbalance), fibrosis, and cardiomyocyte stiffness. We focus primarily on HFpEF caused by metabolic risk factors, such as obesity, T2DM, hypertension, and aging.

CONCLUSION: European guidelines suggest general screening for risk factors, including analysis of lipid profiles in the population of 40-year-old males and 50-year-old or postmenopausal women. Our study documents high prevalence and incidence of CV risk factors together with insufficient control of the risk factors in Czech patients of this age range. This finding suggests that preventive examinations should be undertaken earlier (e.g., in 30-year-old males and 40-year-old women). Exact timing of the preventive check-ups to yield the best cost-benefit ratio needs to be verified. PMID: 32592555 [PubMed - as supplied by publisher]

Abstract Multiple myeloma (MM) is a haematological malignancy arising from monoclonal proliferation of plasma cells in the bone marrow, resulting in the presence of paraproteins or M-protein in serum. The involvement of paraproteins produced by malignant plasma cells in the development of hyperlipidaemia and low-HDL cholesterol has been described, as has an association with MM and obesity, hypertension, and type 2 diabetes mellitus, and insulin resistance, that is, features of the metabolic syndrome (MS). There is an association between MS components, inflammatory cytokines, and the development of MM, and some dru...

We reported findings from the first 8-month pilot phase of the South African diabetes prevention program. The study was conducted across eight townships (four black and four mixed-ancestry communities) in Cape Town, South Africa, between August 2017 and March 2018. Participants were recruited using both random and self-selected sampling techniques because the former approach proved to be ineffective; <10% of randomly selected individuals consented to participate. Non-laboratory-based diabetes risk screening, using the African diabetes risk score, and based on targeted population specific cut-offs, identified potenti...

Authors: Kitazawa T, Park CH, Hiratani K, Choi JS, Yokozawa T Abstract Metabolic syndrome is a cluster of risk factors for cardiovascular disease and type 2 diabetes mellitus. The risk factors include hypertension, dyslipidemia, hyperglycemia, and central obesity. Various diagnostic criteria have been proposed by different organizations over the past decade. The utilization of traditional Chinese medicine to treat metabolic syndrome has received increasing attention due to its wide availability. In this paper, we report the case of a 68-year-old patient with hypertension, hypercholesterolemia, borderline diabetes, ...

This study aimed to investigate the irisin levels in elderly patients with hypertension, diabetes mellitus type 2, and overweight and obesity, to investigate the possible association between irisin levels and anthropometric and biochemical parameters, and also to assess the irisin levels associated with a risk of hypertension, diabetes mellitus type 2, and overweight and obesity.MethodsA nested case-control study was conducted, with hypertension, diabetes mellitus type 2, and overweight and obesity being set as the case group; 71 elderly patients from the cohort were enrolled in each case group, and 71 healthy elderly from...

This study presents the effects of berberine (BBR) on the aging process resulting in a promising extension of lifespan in model organisms. BBR extended the replicative lifespan, improved the morphology, and boosted rejuvenation markers of replicative senescence in human fetal lung diploid fibroblasts. BBR also rescued senescent cells with late population doubling (PD). Furthermore, the senescence-associated β-galactosidase (SA-β-gal)-positive cell rates of late PD cells grown in the BBR-containing medium were ~72% lower than those of control cells, and its morphology resembled that of young cells. Mechanistically...

Authors: Mühleck F, Laufs U Abstract Coronary artery disease (CAD) is the most frequent cause of morbidity and mortality worldwide. Lifestyle modifications and drug treatment of cardiovascular risk factors are able to effectively prevent CAD. The basis of prevention is the assessment of the individual cardiovascular risk, e.g. by using a validated risk score. Documented evidence for prevention of CAD is available for the control of hypertension using angiotensin-converting enzyme (ACE) inhibitors, angiotensin receptor blockers (ARB) and calcium antagonists, for the treatment of hypercholesterolemia using ...
