INTRODUCTION: An ischemic stroke is an event that occurs due to cerebral vascular disease and is directly related to the degree of vascular damage. This process is associated with atherosclerosis progression and is influenced by the presence of cardiovascular risk factors. AIMS: One of the goals of our research was to examine whether specific medications used for treating hypertension are associated with the development of strokes. METHODS: In a retrospective study of patients who were hospitalized between the years 2003-2008 due to a cerebrovascular accident (CVA) or a transient ischemic attack (TIA), 916 cases of stroke patients were reviewed...

Effective regulation of central blood volume and arterial pressure is critical for optimal cardiovascular homeostasis. Inadequate regulation of mean arterial pressure has important pathophysiological implications including syncope, end organ damage, and stroke. Such regulation requires appropriate central integration of barosensory afferents and reflex autonomic control of the heart and blood vessels. The neural pathways involved with the baroreflex include brainstem nuclei that receive modulatory input from higher brain centres...

Previous studies have suggested that the risk of ischemic stroke increases immediately after drinking coffee. Indeed, drinking coffee, that is, caffeine, acutely increases arterial stiffness as well as blood pressure and peripheral vascular resistance. On the other hand, it has been reported that arterial stiffening is associated with elevation in the pulsatility index (PI) of cerebral blood flow (CBF), which increases the risk of brain disease. However, the effect of drinking coffee on the PI of the CBF and its interaction with arterial stiffness remain unknown...

BACKGROUND AND PURPOSE: The standard for stroke risk stratification is the Framingham Stroke Risk Function (FSRF), an equation requiring an examination for blood pressure assessment, venipuncture for glucose assessment, and ECG to determine atrial fibrillation and heart disease. We assess a self-reported stroke risk function (SRSRF) to stratify stroke risk in comparison to the FSRF. METHODS: Participants from the REGARDS study (Reasons for Geographic and Racial Differences in Stroke) were evaluated at baseline and followed for incident stroke...

Carotid plaque is a good surrogate endpoint for assessing arterial atherosclerosis, and atherosclerosis is a reliable predictor of cardiovascular diseases. However, the effect of body mass index on carotid plaque is unknown. Therefore, we aimed to explore the association between body mass index and carotid plaque in a low-income Chinese population. Residents aged ≥45 years and free of stroke and cardiovascular diseases were enrolled and divided into four groups based on body mass index. B-mode ultrasonography was performed to measure carotid plaque...

BACKGROUND: Current guidelines suggest treating blood pressure above 180/105 mm Hg during the first 24 hours in patients with acute ischemic stroke undergoing any form of recanalization therapy. Currently, no studies exist to guide blood pressure management in patients with stroke treated specifically with mechanical thrombectomy. We aimed to determine the association between blood pressure parameters within the first 24 hours after mechanical thrombectomy and patient outcomes. METHODS AND RESULTS: We retrospectively studied a consecutive sample of adult patients who underwent mechanical thrombectomy for acute ischemic stroke of the anterior cerebral circulation at 3 institutions from March 2015 to October 2016...

Valvulo-arterial impedance (Zva) has been shown to predict worse outcome in medically managed aortic stenosis (AS) patients. We aimed to investigate the association between Zva and left ventricular (LV) adaptation and to explore the predictive value of Zva for cardiac functional recovery and outcome after transcatheter aortic valve replacement (TAVR). We prospectively enrolled 128 patients with AS who underwent TAVR. Zva was calculated as: (systolic blood pressure + mean transaortic gradient)/stroke volume index)...

BACKGROUND AND AIMS: Combined spinal-epidural (CSE) analgesia for labour and delivery is occasionally associated with foetal bradycardia. Decreases in cardiac index (CI) and/or uterine hypertonia are implicated as possible aetiological factors. No study has evaluated CI changes following combined spinal analgesia for labour and delivery. This prospective, double-blind, randomised controlled trial evaluates haemodynamic trends during CSE and epidural analgesia for labour. METHODS: Twenty-six parturients at term requesting labour analgesia were randomised to receive either epidural (E) or CSE analgesia...

Background -It is currently unknown whether intensive blood pressure (BP) lowering beyond that recommended would lead to more lowering of the risk of Left ventricular hypertrophy (LVH) in patients with hypertension, and whether reducing the risk of LVH explains the reported cardiovascular disease (CVD) benefits of intensive BP lowering in this population. Methods -This analysis included 8,164 participants (mean age 67.9 years, 35.3% women, 31.2% blacks) with hypertension but no diabetes from the Systolic Blood Pressure Intervention (SPRINT) Trial; 4,086 randomly assigned to intensive BP lowering (target systolic BP<120mmHg) and 4,078 assigned to standard BP lowering (target systolic BP <140mmHg)...

Dietary nitrate is mainly obtained from vegetables, especially green leafy vegetables and beetroot. As a result of early research, dietary nitrate is currently viewed as a contaminant linked to increased risks of stomach cancer and methaemoglobinaemia. Consequently, nitrate levels are restricted in certain vegetables and in water supplies to ensure exposure levels remain below an acceptable daily intake of 3·7 mg/kg per d. The average nitrate intake in the UK is approximately 70 mg/d, although some population groups, such as vegetarians, may consume three times that amount...
