OBJECTIVE: The baroreceptor at the carotid body plays an important role in hemodynamic autoregulation. Manipulation of the baroreceptor during carotid endarterectomy (CEA) or radial force from carotid artery angioplasty and/or stenting (CAS) may cause both intraoperative and postoperative hemodynamic instability. The purpose of this study is to evaluate the long-term effects of CEA and CAS on blood pressure (BP), heart rate (HR), and subsequent changes on antihypertensive medications...

Cardiovascular (CV) events account for 8% to 13% of deaths after liver transplantation (LT) in adulthood. Although CV risk factors are present, little is known about the prevalence of subclinical CV target organ damage in children after LT. The aim of this prospective observational study was to assess the prevalence of subclinical CV target organ damage in children after LT and to identify risk factors contributing to CV damage as potential targets for clinical intervention. In this study, 104 children after LT (54% female, 46% male, aged 11...

Reliable assessment of small vessel blood flow in the thyroid, without using any contrast agents, can be challenging because of increased physiological motion resulting from its proximity to the pulsating carotid artery. In this study, we hypothesized that correction of tissue motion prior to singular value decomposition (SVD)-based clutter filtering can improve the coherency of the tissue components and, thus, may allow better clutter suppression and visualization of small vessels in the thyroid. We corroborated this hypothesis by conducting phantom and in vivo studies using a clinical ultrasound scanner implemented with compounded plane wave imaging...

BACKGROUND: Arterial stiffness has been associated with renal dysfunction and its progression, but the pathophysiological relation underlying this association has not been fully established, particularly among individuals without hypertension and diabetes. We investigated the cross-sectional associations between arterial stiffness and renal function in adults without cardiovascular disease, and whether this association remained among subjects without hypertension and diabetes. METHODS: All eligible participants from ELSA-Brasil (2008-2010), aged 35 to 74 years (N = 13,586) were included, of whom 7,979 were free from hypertension and diabetes...

Background: Visceral obesity is strongly associated with atherosclerosis. Even though waist circumference (WC) is the most common assessment method of total visceral adipose tissue and cardiometabolic risk, this method lacks direct measurement of adipose tissue and has better correlation to subcutaneous fat rather than visceral fat. We intended to investigate whether epicardial adipose tissue (EAT) is clinically superior to body mass index (BMI) and WC in predicting Framingham risk score (FRS) and carotid intima-media thickness (CIMT)...

The fetal myocardium is known to be sensitive to hemodynamic load, responding to systolic overload with cellular hypertrophy, proliferation and accelerated maturation. However, the fetal cardiac growth response to primary volume overload is unknown. We hypothesized that increased venous return would stimulate fetal cardiomyocyte proliferation and terminal differentiation, particularly in the right ventricle (RV). Sixteen late-gestation fetal sheep had vascular catheters and pulmonary artery flow probes implanted...

BACKGROUND: Obesity is a major health problem due to its high prevalence. The relationship between obesity and cardiovascular disease is unclear. Some studies agree that certain conditions associated with obesity, such as physical inactivity or cardiovascular risk factors, are responsible for cardiovascular risk excess among obese people. Carotid intima-media thickness and carotid plaques (CP) have been associated with cardiovascular adverse events in healthy populations, and recent data suggest a higher prevalence of subclinical carotid atherosclerosis in obese and metabolically unhealthy patients...

PURPOSE: Gender affirming hormone therapy (HT) in transgender men both improves and impairs several surrogate cardiovascular risk markers. However, few prospective works with long follow-up and control group are available. In this context, this work aimed to assess the changes in the metabolic and cardiovascular risk pattern after 12 months of HT in transgender men. Furthermore, we aimed to investigate early effects on target tissues that may reflect an initial vascular damage. METHODS: Prospective observational study, including 20 transgender men, attended in the Gender Identity Unit (UIG) of the Hospital Clinic from July 2013 to November 2015...
