An experimental investigation into cardiovascular, haemodynamic and salivary alpha amylase reactivity to acute stress in Type D individuals.

An experimental investigation into cardiovascular, haemodynamic and salivary alpha amylase reactivity to acute stress in Type D individuals. Stress. 2019 Mar 11;:1-8 Authors: Allen SF, Wetherell MA, Smith MA Abstract Type D personality is characterized by increased social inhibition and negative affectivity. Research demonstrates associations between Type D and poor physical health. Maladaptive sympathetic arousal is suggested as a potential mechanism, however, findings are inconsistent and studies mainly focus on basic cardiovascular parameters. The current study examines cardiovascular and haemodynamic parameters in addition to salivary alpha amylase (sAA) as markers of sympathetic stress reactivity in Type D individuals. Healthy adults (N = 75; 33 Type D; aged 18-42; 64% female) completed a multitasking stressor while continuous beat-to-beat cardiovascular function was measured. Saliva samples were obtained at baseline, pre-task, post-task, +10 min and +20 min post-task. Type Ds exhibited dysfunctional cardiovascular reactivity, characterized by blunted total peripheral resistance, slower stroke volume recovery and potentially unhealthy changes in haemodynamic profile. Alpha amylase reactivity was evident, but group differences were not significant. Findings indicate dysregulated sympathetic reactivity in Type D individuals, exemplified by a maladaptive haemodynamic profile. PMID: 30856045 [PubMed - as supplied by publis...

Publication date: Available online 19 March 2019Source: Anaesthesia &Intensive Care MedicineAuthor(s): Carla Gould, Jon HopperAbstractMaintaining an equilibrium between oxygen supply and demand is a principal function of the cardiovascular system. In times of altered metabolic demand mechanisms exist to maintain the balance between supply and demand. Exercise, haemorrhage and pregnancy all lead to changes in oxygen demand and subsequently modification of cardiac output. During isotonic exercise, metabolic demands of muscle are greatly increased. Sympathetic stimulation and inhibition of the parasympathetic system lead ...

Abstract Obstructive sleep apnea (OSA) is associated with adverse physiologic and biochemical sequelae including systemic inflammation, oxidative stress, increased chemoreceptor reflex activity, sympathetic nervous system activation, and endothelial dysfunction. In addition, compelling data strongly implicate OSA in the development of cardiovascular disease (CVD) including myocardial infarction and stroke. Yet in clinical trials, CPAP therapy alone did not reduce cardiovascular events in intention to treat analyses. Thus, opportunity arises for adjunctive therapy, independent of treating comorbid conditions, to ta...

We aimed to correlate beat-to-beat blood pressure variability (BPV) and heart rate variability (HRV) with Ewing’s test classification. We enrolled patients with acute ischemic stroke. Autonomic function was assessed by Ewing battery and dichotomized into minor or significant group. Beat-to-beat blood pressure and heart rate were monitored for calculating the frequency componen...

Background: Reflex sympathetic dystrophy (RSD) is the common complication among stroke and cerebral injury patients, which is lack of safe and effective treatment. Electroacupuncture (EA) may potentially be a reliably therapy, but the evidence is insufficiency. Methods: Cochrane Library, MEDLINE, Embase, Chinese National Knowledge Infrastructure, Wan Fang Data, the Chinese Biology Medicine disc, etc., were searched, until July 20, 2018. We included random control trials that contrast EA with conventional rehabilitation therapy for the treatment of RSD.

Abstract Early detection and management of elevated blood pressure is crucial in reducing the burden of cardiovascular disease (CVD). The importance of an absolute risk assessment and patient risk stratification has been highlighted in the European hypertension guidelines since 2003. Amongst numerous risk factors influencing patient prognosis, elevated heart rate (HR) has been indicated as important predictor of future risk of hypertension, coronary heart disease, sudden cardiac death, heart failure, CVD, stroke, total cancer and mortality. Given that resting HR can be easily determined in clinical practice and mo...

Clinical Applications of the Polyvagal Theory is another work in the Norton series on interpersonal neurobiology. I have come to believe that at least three theories are indispensable in learning and understanding how and why we behave the way we do — attribution theory, attachment theory, and our underlying physiology of safety, called the polyvagal theory. The polyvagal theory was developed by Stephen Porges and presented to the Society for Psychophysiological Research in 1994. The theory takes into account how our autonomic nervous system is constantly working to keep us safe. Very simply, the components are our ...

CONCLUSION: Based on these findings, it is difficult to reconcile the functional topography of the central autonomic system in term newborns with that currently proposed for the normal mature brain. Further investigation is clearly needed. PMID: 30712058 [PubMed - as supplied by publisher]
