In patients with major cerebral artery disease, lower blood pressure might reduce blood flow in the collateral pathways, thereby impairing the growth of cerebral collaterals, inhibiting hemodynamic improvement. We evaluated the hemodynamic status twice using positron emission tomography and (15)O-gas, over time, in 89 medically treated patients with atherosclerotic internal carotid artery or middle cerebral artery disease that had no ischemic episodes during follow-up (mean, 28 ± 23 months). Changes in the mean hemispheric values of hemodynamic parameters in the territory of the diseased artery at follow-up were correlated with the mean blood pressure values at the baseline and follow-up examinations...

Contemporary medical therapy consists of identification and treatment of all patient-modifiable vascular risk factors. Specific atherosclerotic disease therapies are designed to reduce the risk of thrombosis, and the disease progression in order to reduce the risk of future cardiovascular events. Contemporary medical management emphasizes the need to support the patient in achieving lifestyle modifications and to adjust medication to achieve individualized target values for specific quantifiable risk factors...

The pathophysiology and natural history of atherosclerotic carotid disease is predicated on a more extensive knowledge of lesion progression gained in the studies conducted in the coronary arteries, and these will be reviewed. While the precise sequence of lesion progression leading to carotid plaque vulnerability and cerebrovascular events remain less well understood, specific early and more advanced progressive lesion morphologies associated with stroke risk have been characterized. Of late, there has been a conscious effort for stroke prevention in symptomatic and asymptomatic patients to move beyond luminal stenosis as the only guidance to predict future cerebrovascular events...

Risk factors for coronary artery disease are relatively common among patients with urolithiasis. Increased risk of myocardial infarction and carotid atherosclerosis in young adults have been noted. The authors of this article on vascular disease and kidney stones make the case for using routine imaging studies to screen for patients with cardiovascular risk factors.

Proprotein convertase subtilisin/kexin type 9 (PCSK9) is an important circulating serine protease in low-density lipoprotein cholesterol (LDL-C) metabolism. Increased plasma PCSK9 levels lead to increased plasma levels of LDL-C and an increased risk of cardiovascular disease (CVD). LDL-C is positively correlated with arterial stiffness, a surrogate endpoint of CVD. However, whether plasma levels of PCSK9 could influence arterial stiffness is still unclear. Our study examined the relationship between plasma levels of PCSK9 and arterial stiffness (carotid-femoral pulse wave velocity (cf-PWV)) in a community-based population...

BACKGROUND: Hemodynamic changes frequently occur after carotid artery stenting (CAS), and in some patients these changes, particularly hypotension, may be prolonged. There are discrepant results for predicting patients at high risk for these prolonged hemodynamic changes and identifying the effect on clinical outcome. In this study, we aimed to determine the frequency, predictors and consequences associated with prolonged hypotension (PH) after CAS in our center. METHODS: We retrospectively analyzed the demographics, risk factors, nature of carotid disease, degree of stenosis of both internal carotid arteries, stent diameter and site of dilatation during stenting in 137 CAS procedures...

A novel hypothesis proposes that "cardio-cephalic neural crest (NC) syndrome," i.e. cephalic NC including cardiac NC, contributes to the concurrent occurrence of vascular diseases in the cardio- and cerebrovascular regions. NC is a transient structure present in early embryogenesis. Cephalic NC provides mesenchymal cells to the vascular media in these regions. Concurrent cardio- and cerebrovascular lesions have been reported in PHACE syndrome, ACTA2 mutation syndrome, and less frequently in the spontaneous occlusion of the circle of Willis (so-called moyamoya disease)...

Homocysteine (Hcy) is an important and independent risk factor for atherosclerotic diseases, such as coronary artery disease and ischemic cerebrovascular disease. Increased carotid artery intima-media thickness (IMT) is a non-invasive marker of systemic atherosclerosis. Allicin treatment may decrease serum Hcy levels and improve impaired endothelial function in rats with hyperhomocysteinemia (HHcy). The present study hypothesized that allicin has an anti-atherosclerotic effect in coronary heart disease and tested the effects of allicin treatment on carotid artery IMT and plasma Hcy levels in coronary heart disease patients with HHcy...

Although cerebrovascular diseases have been considered as risk factors for cognitive decline and dementia, the associations between atherosclerosis and Alzheimer's disease (AD) have not been fully examined and remain controversial. The aim of this three-year prospective study was to investigate whether arotid artery atherosclerosis accelerates cognitive impairment in AD patients. The association of carotid intimal medial thickness (IMT) with prospective trajectories of cognitive function was assessed among 521 patients with light to moderate AD, and 437 AD patients were followed up annually for 3 years...

Increasing evidence supports the importance of socioeconomic factors in the development of atherosclerotic cardiovascular disease. However, the association of childhood socioeconomic status (SES) with arterial stiffness in adulthood has not been reported. Our aim was to determine whether higher childhood family-level SES is associated with lower arterial stiffness in adulthood. The analyses were performed using data gathered within the longitudinal Young Finns Study. The sample comprised 2566 participants who had data concerning family SES at ages 3 to 18 years in 1980 and arterial pulse wave velocity and carotid artery distensibility measured 21 or 27 years later in adulthood...

Familial hypercholesterolemia (FH) is an autosomal dominant disorder characterized by impaired clearance of low-density lipoprotein cholesterol. Given limitations in pharmacologic therapy and the significant morbidity and mortality associated with this disease, liver transplantation may be offered to select homozygous FH patients in childhood in an effort to slow progression of atherosclerotic cardiovascular disease. In rare cases, domino liver transplantation can be performed, transplanting the livers of patients with various metabolic disorders into elderly recipients whose projected survival precludes prolonged waiting on the transplant list...

BACKGROUND: Subjects with higher carotid-femoral pulse wave velocity (cfPWV) will be at an increased risk for cardiovascular (CV) events in future. Resistin is an inflammatory mediator and a biomarker of CV diseases. We evaluated the association between serum resistin and aortic stiffness in patients with coronary artery disease (CAD). METHODS: A total of 104 patients with CAD were enrolled in this study. cfPWV was measured using the SphygmoCor system. Patients with cfPWV >10 m/s were defined as the high aortic stiffness group...

Osteogenesis imperfecta (OI) is a heterogeneous group of inherited disorders that occur owing to the abnormalities in type 1 collagen, and is characterized by increased bone fragility and other extraskeletal manifestations. OI may be associated with vascular complications such as aortic and cervical artery dissection, carotid cavernous fistula, and coronary artery aneurysms but unlike other connective tissue diseases, the cerebrovascular system is less frequently involved. We report rare case of 50 year female patient who was diagnosed with OI following right frontal haemorrhage secondary to a ruptured middle cerebral artery mirror aneurysm...
