Abstract Background Patients with HIV are more likely to present with cardiovascular disease when compared to the general population. Objective This was a case-control study that aimed to assess which factors were associated with a reduction in the carotid intima-media thickness (IMT) and an increase in the brachial artery flow-mediated dilation (FMD) in HIV patients who received atorvastatin + aspirin during a period of 6 months. Methods A secondary analysis of a clinical trial was conducted, which included people living […]

The endothelium is considered an active and dynamic tissue with important properties such as maintenance of blood circulation, regulation of vascular tone, microvascular permeability, signaling, and vascular angiogenesis and inflammatory response. The endothelium allows the connection among components of the circulation and body systems. Endothelial cells produce and, depending on the stimulus received, release factors that lead to vascular smooth muscle cells contraction or relaxation. Vascular tone control by the endothelium is modulated by the production and release of mediators […]

Abstract Background: Individuals with a family history of systemic arterial hypertension (FHSAH) and / or prehypertension have a higher risk of developing this pathology. Objective: To evaluate the autonomic and vascular functions of prehypertensive patients with FHSAH. Methods: Twenty-five young volunteers with FHSAH, 14 normotensive and 11 prehypertensive subjects were submitted to vascular function evaluation by forearm vascular conductance(VC) during resting and reactive hyperemia (Hokanson®) and cardiac and peripheral autonomic modulation, quantified, respectively, by spectral analysis of heart rate (ECG) […]
