We performed a study on 25 common carotid arteries (CCA) affected by atherosclerotic plaques, comparing them to 25 normal CCA. We researched the presence and localisation of atrial natriuretic factor (ANF) and oxytocin (OX) by immunohistochemistry. We found ANF abundantly expressed in plaques, mainly localising in intima and subintima layers; by contrast normal vessels were scarcely positive or negative; finally, OX resulted negative or weakly positive in both atherosclerotic and normal vessels. Our results show for the first time ANF presence in atherosclerotic plaques of CCA and are in agreement with other studies, mainly performed in vitro, that hypothesise the involvement of this molecule in the modulation of atherosclerotic inflammatory lesions and its use as anti-inflammatory agent.

Background: Erectile dysfunction is a condition with a rapidly increasing prevalence globally with a strong correlation to the increase in obesity and cardiovascular disease rates.
Aim: The aim of the current study is to investigate the potential role of tubacin, a histone deacetylase 6 (HDAC6) inhibitor, in restoring erectile function in a hypercholesterolemia-induced endothelial dysfunction model.
Methods: Thirty-nine male C57Bl/6 J mice were divided into 3 groups.

Background: The prevalence of very high-risk atherosclerotic cardiovascular disease (ASCVD) is significant in China, with suboptimal rates of low-density lipoprotein cholesterol (LDL-C) compliance exacerbating plaque instability and causing a higher incidence of major adverse cardiac events (MACEs). Proprotein convertase subtilisin/kexin type 9 inhibitors (PCSK9i) are effective in reducing LDL-C levels, increase the stability of vulnerable plaque, and influence the progression of atherosclerosis through multiple mechanisms as demonstrated in animal studies. However, there is currently a lack of evidence regarding the efficacy and safety of high-intensity statin therapy combined with PCSK9i in the secondary prevention of ASCVD in the Chinese population.

The carotid and vertebral arteries are principal conduits for cerebral blood supply and are common sites for atherosclerotic plaque formation. To date, there has been extensive clinical and hemodynamic reporting on carotid arteries; however, studies focusing on the hemodynamic characteristics of the vertebral artery (VA) are notably scarce. This article presents a systematic analysis of the impact of VA diameter and the angle of divergence from the subclavian artery (SA) on hemodynamic properties, facilitated by the construction of an idealized VA geometric model.

Background: Diabetes mellitus is an established cardiovascular risk factor. We assessed the impact of diabetes mellitus on quantitative plaque and long-term outcomes in patients with and without diabetes mellitus in the Scottish COmputed Tomography of the HEART (SCOT-HEART) trial.
Methods: Coronary artery calcium (CAC) was assessed on non-contrast computed tomography (CT).

IgG4-related disease (IgG4-RD) is an immune-mediated fibroinflammatory disorder that can affect multiple organs throughout the body, predominantly in middle-aged and elderly males, with a male-to-female ratio of 2꞉1 to 3꞉1. IgG4-related retroperitoneal fibrosis (IgG4-RPF), a rare subtype of IgG4-RD, has an unclear etiology, and its comorbidity with type 2 diabetes mellitus is also uncommon. A lack of awareness of this condition in clinical practice can easily lead to misdiagnosis.
