A further study was carried out on the relationship between coronary artery geometry and atherosclerotic involvement. The results show that: a) the coronary artery geometry may expose an individual at an early age to an increased risk for developing atherosclerotic lesions; b) the presence, in the coronary arterial bed of vessels with large diameters (greater than 2 mm) and the succession of numerous branching points also appeared as atherogenic conditions; c) the type of atherosclerotic lesion (proliferative, insudative, necrotic, lipid-rich) was, in our material strongly influenced by the geometry of branch sites.

The aim of this study was to explore whether 24-h ambulatory central (aortic) blood pressure (BP) has an advantage over office central aortic BP in screening for hypertension-mediated target organ damage (HMOD). A total of 714 inpatients with primary hypertension and the presence of several cardiovascular risk factors or complications involving clinical HMOD were enrolled. Twenty-four hour central aortic BP was measured by means of a noninvasive automated oscillometric device (Mobil-O-Graph).

Background And Aims: Several systemic autoimmune diseases predispose to the enhancement of Atherosclerotic Cardiovascular Disease (ASCVD). These findings underline the role of inflammation in atherogenesis. Dermatomyositis (DM) and polymyositis (PM) are polygenic autoimmune disorders involving mainly skeletal muscles.

CHI3L1 is strongly associated with atherosclerosis, but its role in macrophages remains unknown. In this study, we observed a significant up-regulation of CHI3L1 in both carotid plaques and serum of symptomatic patients, and demonstrated that CHI3L1 impairs the efferocytosis of macrophages by down-regulating crucial efferocytic mediator MFGE8 through inhibiting ATF2, which binds directly to the enhancer of MFGE8. In human plaques, we observed a negative correlation between CHI3L1 expression and both ATF2 and MFGE8 levels, further proved their involvement in plaque destabilization.

Intracranial atherosclerotic stenosis (ICAS) and intracranial aneurysms are prevalent conditions in the cerebrovascular system. ICAS causes a narrowing of the arterial lumen, thereby restricting blood flow, while aneurysms involve the ballooning of blood vessels. Both conditions can lead to severe outcomes, such as stroke or vessel rupture, which can be fatal.

Transaortic endarterectomy (TE) is an effective and durable method of restoring patency in the aorta afflicted with atherosclerotic disease, which most commonly affects the infrarenal aorta and common iliac artery. When the suprarenal aorta is involved, the disease is usually confined to the orifices of the visceral vessels without obstruction of the aortic lumen. In rare cases, dense, calcified, exophytic, and amorphous lesions causing severe luminal obstruction, termed coral reef atherosclerosis (CRA) of the suprarenal aorta, may occur.
