Background: Sepsis-induced cardiomyopathy (SICM) often occurs in the acute phase of sepsis and is associated with increased mortality due to cardiac dysfunction. The pathogenesis remains poorly understood, and no specific treatments are available. Although SICM is considered reversible, emerging evidence suggests potential long-term sequelae.

Chronic pain is a prevalent condition affecting a significant portion of the global population and is known to be associated with an increased risk of cardiovascular diseases. Despite the clinical relevance, the mechanisms underlying the link between chronic pain and myocardial ischemia-reperfusion (MI/R) injury remain poorly understood. This study aimed to investigate the role of the superior cervical ganglion (SCG) in mediating the effects of chronic pain on MI/R injury and to develop a novel therapeutic strategy.

The effect of epidural infusion of dexmedetomidine on haemodynamics is unclear. This study aimed to explore the effects of epidural or intravenous infusion of dexmedetomidine on haemodynamics during lower extremity varicose veins surgery (saphenectomy) under epidural anaesthesia. Ninety patients were randomly allocated to three groups: ED group (epidural: 0.

Spinal cord injuries (SCIs) can lead to severe neuropathic pain and increased risk of myocardial infarction and heart failure; therefore, the use of analgesics against SCI-induced pain should be minimized because of their adverse effects on the cardiovascular system. Ivabradine, a blocker of hyperpolarization-activated cyclic nucleotide-gated cation (HCN) channels, is used as a bradycardic agent, but recent studies focused on it as an analgesic agent for peripheral neuropathic pain. However, the analgesic effects of ivabradine on central neuropathic pain, such as SCI-induced pain, have not been examined.

This study aimed to investigate the effects of chronic sympathoinhibition on glucose uptake by the myocardium and by the skeletal muscle in an animal model of obesity associated with leptin signaling deficiency. 6 obese Zucker rats (OZR) and 6 control Lean Zucker rats (LZR) were studied during basal conditions, chronic clonidine administration (30 days, 300 µg/kg), and washout recovery period. Glucose uptake in the myocardium and in the skeletal muscle was measured using positron emission tomography (PET) and 2-[18F] fluoro-2-deoxy-D-glucose ([18F]FDG).
