Preventive Effects of Transcutaneous Electrical Acustimulation on Ischemic Stroke-Induced Constipation Mediated via the Autonomic Pathway.
CONCLUSION: Ischemic stroke patients are predisposed to autonomic function imbalance. TEA was effective in the prevention of stroke-induced constipation, and the effect was possibly mediated via the autonomic function. PMID: 29746169 [PubMed - as supplied by publisher]

Heart Rate Variability During Early Mobilization in Patients with Acute Ischemic Stroke
Autonomic dysfunction is one of the predictors of poor outcome in patients with acute ischemic stroke. We compared the heart rate variability (HRV) during early mobilization in patients with or without neurological deterioration (ND). We enrolled 7 acute ischemic patients with ND and 14 without ND and measured their HRV in the rest and mobilization by electrocardiography. There was a significant difference in sympathetic nervous activity during mobilization between the 2 groups. However, no significant differences in blood pressure, heart rate, and parasympathetic nerve activity were observed. In patients with acute ischem...

A Simple Gain-Based Evaluation of the Video Head Impulse Test Reliably Detects Normal Vestibulo-Ocular Reflex Indicative of Stroke in Patients With Acute Vestibular Syndrome
Conclusion: A simple, automated, gain-based evaluation of the vHIT reliably detects normal/central VOR and may be a feasible and effective tool to screen AVS patients for potentially underlying stroke in the emergency setting.

Brain-heart axis - Review Article.
Authors: Manea MM, Comsa M, Minca A, Dragos D, Popa C Abstract UNLABELLED: There has been a large confirmation over the last decades that stroke may produce cardiac changes (echocardiographic, electrocardiographic, enzymatic). In ischemic stroke, systolic dysfunction is associated with a high risk of mortality during hospitalization. A recent study demonstrated that cardiac diastolic dysfunction could also accompany acute stroke besides the systolic dysfunction already pointed out by previous studies, being a predictive marker of acute cerebrovascular events. Increased sympathetic activity is contributory, inducing...

Sickle Cell Disease Subjects Have a Distinct Abnormal Autonomic Phenotype Characterized by Peripheral Vasoconstriction With Blunted Cardiac Response to Head-Up Tilt
Conclusion We have shown that SCD subjects are much more likely than non-SCD subjects to have impaired cardiac, but intact peripheral responses to orthostatic stress induced by HUT. These abnormal responses are associated with low baseline cardiac parasympathetic activity, independent of hemoglobin level. The classification of autonomic phenotypes based on HUT response may have potential use for predicting disease severity, guiding and targeting treatments/interventions to alleviate the risk of adverse outcomes in SCD. Ethics Statement All experiments were conducted at Children’s Hospital Los Angeles (CHLA). The ...

Blood pressure in professional male football players in Norway
Conclusion: Although the prevalence of high BP in professional football players was low, our data indicate a novel association between elevated BP and reduced arterial compliance, increased left ventricle mass and left atrium volume even in young athletes. This emphasizes closer focus on BP measurements and standardized follow-up after preparticipation screening of athletes.

The risk of resting heart rate on vascular events and mortality in vascular patients
Conclusions: Elevated RHR is associated with increased risk for mortality but not for myocardial infarction or stroke in patients with manifest vascular diseases irrespective of location of vascular disease.

Analysis of cardiorespiratory phase coupling and cardiovascular autonomic responses during food ingestion
Publication date: 15 May 2016 Source:Physiology & Behavior, Volume 159 Author(s): Kyuichi Niizeki, Tadashi Saitoh The present study analyzed whether the phase coherency (λ) of respiratory sinus arrhythmia (RSA) is altered by food ingestion in healthy young subjects. After 5min of resting control, 13 healthy volunteers were asked to eat a solid meal with access to water at their own pace, followed by 5min of the postprandial state. The R-R interval (RRI), beat-to-beat blood pressure (BP), and respiratory activity were recorded using electrocardiography, a Finapres device, and inductance plethysmography, respect...

Acute Right Middle Cerebral Artery Occlusion Resulting in Acute Systolic Heart Failure, Cerebral T-Waves, and QTc Prolongation: A Case Report
Conclusions: Acute ischemic infarcts, particularly to the right insular cortex, can result in ECG abnormalities, such as QT prolongation and T-wave inversion, as well as acute systolic heart failure; all of which may be reversible after the acute phase of the stroke.

Autonomic cardiovascular dysregulation at rest and during stress in chronically low blood pressure.
Chronic low blood pressure (hypotension) is accompanied by symptoms such as fatigue, reduced drive, faintness, dizziness, cold limbs, and concentration difficulties. The study explored the involvement of aberrances in autonomic cardiovascular control in the origin of this condition. In 40 hypotensive and 40 normotensive subjects, impedance cardiography, electrocardiography, and continuous blood pressure recordings were performed at rest and during stress induced by mental calculation. Parameters of cardiac sympathetic control (i.e., stroke volume, cardiac output, pre-ejection period, total peripheral resistance), parasympa...

Electrocardiographic abnormalities and cardiac arrhythmias in structural brain lesions
Abstract: Cardiac arrhythmias and electrocardiographic abnormalities are frequently observed after acute cerebrovascular events. The precise mechanism that leads to the development of these arrhythmias is still uncertain, though increasing evidence suggests that it is mainly due to autonomic nervous system dysregulation.In massive brain lesions sympathetic predominance and parasympathetic withdrawal during the first 72h are associated with the occurrence of severe secondary complications in the first week. Right insular cortex lesions are also related with sympathetic overactivation and with a higher incidence of electroca...

A Novel Noninvasive Device to Assess Sympathetic Nervous System Function in Patients With Heart Failure
Discussion: Although the VU-AMS version 5fs system detected anticipated hemodynamic and sympathetic nervous system changes to postural shift in participants (n = 10), the elimination of 64% (n = 18) of the sample because of scoring difficulties limits the use of this impedance cardiography device using standard scoring algorithms in persons with heart failure with reduced ejection fraction.

Effect of acupuncture on the hemodynamic system. Correlation between heart rate, cardiac output and blood pressure
Acupuncture stimulation can induce reduction of the heart rate via a somato-autonomic reflex. However, it is unknown whether acupuncture influences also other hemodynamics parameters. The present study was designed to investigate comprehensively the changes of cardiovascular responses during acupuncture stimulation. Twelve healthy volunteers (mean age: 22 ±1 years) participated in the study. Heart rate, stroke volume, cardiac output and blood pressure were measured in the subjects in supine position by means of the electrocardiogram, transthoracic impedance cardiogram and continuous non-invasive finger blood pressure.

Systemic Complications Following Aneurysmal Subarachnoid Hemorrhage
AbstractMany systemic complications follow aneurysmal subarachnoid hemorrhage and are primarily due to sympathetic nervous system activation. These complications play an important role in the overall outcome of patients. The purpose of this review is to provide an update on the diagnosis, pathophysiology, and management of systemic complications specifically associated with aneurysmal subarachnoid hemorrhage. Special focus has been made on systemic complications that occur more frequently in patients with aneurysmal subarachnoid hemorrhage compared to other stroke subtypes and in the neurocritical care patient population. ...
