We report a patient with autonomic dysfunction following acute SARS-CoV-2 infection, presenting progressively worsening severe orthostatic hypotension to the point where she could no longer sit or stand. The experienced delay in diagnosis after an initial misdiagnosis of functional neurological disorder. Persistent symptoms prompted us re-examine and explore other diagnostic tools, which ultimately allowed identify treat immune-mediated (OH). identified autoantibodies (AAB) targeting nervous...
Background Arterial hypertension is characterized by microvasculature changes and reduced tissue perfusion. It unknown whether a sexual dimorphism of renal microcirculation present in patients with arterial hypertension. We aimed to compare the cortical women men evaluate their response sympathetic stimulation cold pressor test (CPT). Methods The perfusion index (PI) measured contrast‐enhanced ultrasonography was used as proxy microcirculation. PI at rest during 2‐minute CPT linear...
Microvascular structural alteration and dysfunction is a hallmark of arterial hypertension. So far, the visualization quantification renal microcirculation in humans has been hampered by lack non-nephrotoxic non-invasive radiologic techniques. Contrast-enhanced ultrasonography (CEUS) an appealing method to investigate not investigated this setting. We aimed compare normotensive (NT) hypertensive (HT) participants using CEUS at rest during sympathetic stress test.
May Measurement Month (MMM) is an international screening campaign for arterial hypertension (HT) organised by the International Society of Hypertension and World League. It aims at raising awareness elevated blood pressure (BP) in population. The goal this analysis was to assess results obtained Swiss pharmacies during a 3-year campaign.Swiss data from MMM17 MMM19 campaigns were extracted global MMM database. conducted specifically on measures taken pharmacies. BP questionnaire including...
Background: Accurate blood pressure (BP) measurement is essential for the correct diagnosis and management of hypertension (HTN) especially in elderly population. As with all BP devices, accuracy cuffless devices must be verified. This study (NCT04027777) aimed to evaluate performance a wrist optical device an population cohort different body positions auscultation as reference measurement.
Objective: Dark chocolate (DC) is rich in calories but also cocoa, a substance with anti-oxidative and antihypertensive properties. Acute intake of DC vasodilates coronary arteries, the effect on blood pressure renal hemodynamics poorly understood. The aim this randomized, placebo controlled study was to investigate whether induces changes perfusion as assessed Doppler ultrasound, both at rest during sympathetic stimulation, compared cocoa-free white (WC). Design method: Seventeen healthy...
Objective: Arterial hypertension is associated with alterations in the morphology and function of microvascular structure. Whether these changes are sex-specific kidney hypertensive patients unknown. Contrast-enhanced ultrasonography (CEUS) enables quantification renal microcirculation. The objective this study was to compare cortical microcirculation (HT) women versus HT men, assess response a cold pressure test (CPT). Design method: This prospective observational study. Hypertensive...
Abstract Context The Swiss Federal Food Safety and Veterinary Office (FSVO) commissioned in 2021 the second National Survey on Salt Consumption general adult population, namely Study 2 (SSS2), with a design similar to SSS1 (2010‐2011) for comparability. Methods This survey, conducted 2022‐2023 includes random sample of 863 permanent residents Switzerland (450 men 413 women) covering three main linguistic regions (French, German, Italian) Switzerland. Dietary salt (NaCl), potassium (K),...
Objective: It remains unclear whether non-occlusive blood pressure (BP) monitoring devices yield equivalent performance across different age categories. We sought to compare the of BP measurements conducted by Aktiia cuffless monitor in adult and elderly populations, body positions. Design method: Two cohorts patients (adult, 21-65 years; elderly, 65-85 years) were recruited for a prospective clinical study (NCT04027777, Lausanne University Hospital, Switzerland, August/2019–March/2022)....
An increased sympathetic tone is associated with the initiation and maintenance of most forms arterial hypertension. Background activity a core network neurons in brain brainstem supposed to be important for long-term blood pressure control. Imaging techniques such as oxygen level dependant magnetic resonance imaging (BOLD MRI) are now capable detecting changes oxygenation within using levels. So far, BOLD fMRI signal intensity provoked by cold pressor test (CPT) have not been compared...
