Sympathetic activation in congestive heart failure: an updated overview
AbstractConclusive evidence demonstrates that the sympathetic nervous system activation is a hallmark of congestive heart failure. This has been shown via a variety of biochemical, neurophysiological, and neuroimaging approaches for studying human sympathetic neural function. The sympathetic activation appears to be an early phenomenon in the clinical course of the disease, closely related to its severity and potentiated by the concomitant presence of other comorbidities, such as obesity, diabetes mellitus, metabolic syndrome, hypertension, and renal failure. The adrenergic overdrive in heart failure is associated with other sympathetic abnormalities, such as the downregulation of beta-adrenergic adrenoreceptors at cardiac level, and exerts unfavorable consequences on the cardiovascular system. These include the endothelial dysfunction, the development of left ventricular hypertrophy, the atherosclerosis development, as well as the generation of atrial and ventricular arrhythmias, and, at very extreme levels of sympathetic activation, the occurrence of microscopic myocardial necrosis. Given the close direct independent relationships detected in heart failure between sympathetic activation and mortality, the adrenergic overdrive has become a target of neuromodulatory therapeutic interventions, which include non-pharmacological, pharmacological, and device-based interventions. For some of these approaches (specifically bilateral renal nerves ablation and carotid baroreceptor st...

Authors: Nyamu DG, Guantai AN, Osanjo GO, Godman B, Aklillu E Abstract Background: Patients' profiles affect the outcome with warfarin; however, this data, and its implications, is scarce in resource-poor countries such as Kenya without access to pharmacogenetics or regular INR testing.Objectives: To characterize the profiles of patients on long-term warfarin therapy and subsequently use the findings to guide future anticoagulation management.Methods: Cross-sectional study undertaken among 180 adult patients receiving warfarin therapy in anticoagulation clinics at a leading referral hospital in Kenya. Sociodemograp...
CONCLUSION: All these results indicate that SQC is an effective preventive and protective drug on skeletal muscle of diabetic macrovasculopathy, and could alleviate skeletal muscle tissue damage through affecting biological functions related to cell death and cell adhesion.

Authors: Wyssmüller I, Schaal K, Wolf S, Zinkernagel M Abstract BACKGROUND: It has previously been shown that the process of anti-vascular endothelial growth factor (VEGF) injections can lead to a significant increase of blood pressure. The aim of this study was to investigate whether this blood pressure increase was reproducible with repeated anti-VEGF injections. PATIENTS AND METHODS: Patients with a systolic blood pressure of ≥ 180 mmHg during previous injections who were scheduled for further injections were asked to participate in this study. Systolic as well as diastolic blood pressu...

In conclusion, chronic supplementation with 1% glycine did not have any significant detrimental side effects in our model. However, more studies are still necessary to evaluate the effect of 1% glycine supplementation in humans. PMID: 32091321 [PubMed - as supplied by publisher]
Authors: Boutou AK, Pitsiou G Abstract Introduction: Pulmonary arterial hypertension (PAH) is still a chronic disorder characterized by high morbidity and mortality. Chronic thromboembolic pulmonary hypertension (CTEPH) is another form of pulmonary hypertension (PH) for which pulmonary endarterectomy (PEA) is the treatment of choice. However, not all patients are operable, while PH is often recurrent or persistent. Thus, for both disorders novel treatment options are urgently needed.Areas covered: This review describes the mechanism of action of riociguat, a soluble guanylate cyclase (sGC) stimulator, with a dual m...
