X-ray examination of the lumbar spine of 268 Greenlanders and a corresponding number of Danes were reviewed in order to diagnose arteriosclerotic lesions of the abdominal aorta. In 10.4% of the Greenlanders and 11.6% of the Danes major calcifications were found. The two groups did not differ in distribution of age and sex of patients with arteriosclerotic lesions. It is known that arteriosclerotic complications occur less frequently in Greenlanders than in Danes. The study seems to indicate that this cannot be explained by a rarer occurrence of generalized arteriosclerosis.

The accumulation of uric acid in arteriosclerotic plaques has recently attracted attention. Because the interaction between hyperuricemia and atherosclerosis is complex, the details remain obscure. We aimed to elucidate the clinical effect of monosodium urate monohydrate (MSU) deposition on carotid plaques.

The renin-angiotensin system (RAS), composed mainly of renin, angiotensin, and aldosterone, is a key endocrine pathway involved in cardiovascular activity regulation. Under physiological conditions, the RAS plays a vital role in water and salt metabolism, blood pressure regulation, and electrolyte balance. Angiotensin II (Ang II) is the most important active component of the RAS, and its receptors are concentrated in vascular, pulmonary, cardiac, and renal tissues in vivo.

Background: Intravascular ultrasound-determined plaque protrusion (PP) during carotid artery stenting (CAS) using conventional stents is reported in 7.6% to 12% of cases and is associated with periprocedural cerebral embolism. The Casper/Roadsaver stent (CRS) is a dual-layer micromesh stent designed to reduce the risk of PP, with a mesh cell diameter 4-fold smaller size than that of conventional stents.

Atherosclerosis is a progressive inflammatory disease within the large and medium arteries. SUCNR1(Succinate receptor 1) has been reported to regulate the inflammatory response in cardiovascular diseases, but how it works in atherosclerosis remains unclear. In this study, we observed that SUCNR1 is upregulated in endothelial cells within human atherosclerotic lesions.
