Objective: To investigate the effect of laughter and mental stress on arterial stiffness and central hemodynamics. Arterial stiffness and wave reflections are independent predictors of cardiovascular risk. Chronic psychological stress is an independent risk factor for cardiovascular events, whereas acute stress deteriorates vascular function. Methods: Eighteen healthy individuals were studied on three occasions, according to a randomized, single-blind, crossover, sham procedure-controlled… Expand

Impact of acute mental stress on segmental arterial stiffness
TLDR
The findings suggest that acute MS elicits an increase in arterial stiffness in various segments and this arterial stiffening is not uniform among the segments. Expand
Acute mental stress-caused arterial stiffening can be counteracted by brief aerobic exercise.
TLDR
The findings of the present study reveal that brief aerobic exercise counteracts arterial stiffening caused by acute MS. Expand
Psychological stress and arterial stiffness in Korean Americans.
TLDR
It is demonstrated that anxiety is a significant and independent determinant of arterial stiffness, and these findings suggest that arterIAL stiffness may be a pathway to explain the connection between anxiety and hypertension risk. Expand
Hemodynamic, catecholamine, vasomotor and vascular responses: Determinants of myocardial ischemia during mental stress.
TLDR
Ischemia during conventional stress testing and hemodynamic and vasoconstrictive responses to mental stress can help predict subjects with CAD at greater risk of developing MSIMI. Expand
Effect of mirthful laughter on vascular function.
TLDR
It is suggested that mirthful laughter elicited by comic movies induces beneficial impact on vascular function. Expand
Central hemodynamics and arterial stiffness during the finals of the world cup soccer championship 2010.
TLDR
The authors observed persistent changes in central hemodynamics 2h after emotional stress and prolonged elevation of central systolic blood and pulse pressure, which contribute to the understanding of the increased risk of cardiovascular events in emotional stress. Expand
Mental stress, arterial stiffness, central pressures, and cardiovascular risk.
TLDR
The authors eloquently present the pros and cons of laboratory tests that are used to provoke stress, highlight the importance of immediate response to stimuli, as well as of subsequent poststress recovery, and focus on published studies that present longitudinal data regarding CV risk of the subjects that were exposed to the stressor test.

Music decreases aortic stiffness and wave reflections.
TLDR
Music, both classical and rock, decreases aortic stiffness and wave reflections, which may have important implications, extending the spectrum of lifestyle modifications that can ameliorate arterial function. Expand
Impact of Mental and Physical Stress on Blood Pressure and Pulse Pressure under Normobaric versus Hypoxic Conditions
TLDR
Divergent cardiovascular reactions can be explained by applying the multidimensional aspects of the biopsychosocial concept. Expand

TLDR
All the vital parameters values like Pulse Rate, Systolic Blood Pressure and Diastolic Blood pressure were reduced after laughter therapy and were shown significant incidence. Expand

Acute Mental Stress Has a Prolonged Unfavorable Effect on Arterial Stiffness and Wave Reflections
TLDR
The results provide important mechanistic links between acute mental stress and increased cardiovascular risk and given the important pathophysiologic and prognostic role of these parameters, these parameters have been identified as independent markers and prognosisators of cardiovascular risk. Expand
Hemodynamics and Arterial Properties in Response to Mental Stress in Individuals with Mild Hypertension
TLDR
Hemodynamic and arterial responses to mental stress in individuals with normal BP and mild hypertension were similar; several parameters, however, were different in basal state. Expand
Acute Systemic Inflammation Increases Arterial Stiffness and Decreases Wave Reflections in Healthy Individuals
TLDR
This is the first study to show through a cause-and-effect relationship that acute systemic inflammation leads to deterioration of large-artery stiffness and to a decrease in wave reflections, given the importance of aortic stiffness for cardiovascular function and risk. Expand
Inhibition of cortisol production with metyrapone prevents mental stress-induced endothelial dysfunction and baroreflex impairment.
TLDR
Stress-related endothelial dysfunction and BRS impairment can be prevented by blocking cortisol production with metyrapone, demonstrating a direct or facilitative role for cortisol in these phenomena and suggesting mechanisms by which stress contributes to CHD and sudden cardiac death. Expand
Impact of cinematic viewing on endothelial function
TLDR
Because cinematic viewing evokes a range of negative and positive emotions, the present study was designed to compare the effect of mental stress versus laughter on endothelial function. Expand
Effect of chronic coffee consumption on aortic stiffness and wave reflections in hypertensive patients
TLDR
Coffee consumption is associated with increased wave reflections, but not aortic stiffness in never-treated hypertensive patients, and this finding may have important clinical implications for cardiovascular health in hypertensive subjects. Expand
Mental Stress Induces Transient Endothelial Dysfunction in Humans
TLDR
These findings suggest that brief episodes of mental stress, similar to those encountered in everyday life, may cause transient endothelial dysfunction in healthy young individuals and might represent a mechanistic link between mental stress and atherogenesis. Expand
Acute mental stress elicits delayed increases in circulating inflammatory cytokine levels.
TLDR
It is indicated that inflammatory cytokines respond to acute mental stress in humans with delayed increases, and suggest that individual differences in cytokine responses are associated with sympathetic reactivity. Expand
Endothelial Function Is Associated With Pulse Pressure, Pulse Wave Velocity, and Augmentation Index in Healthy Humans
TLDR
In healthy individuals, a decline in endothelial function is associated with increased large artery stiffness, wave reflections, and central pulse pressure, and inversely associated with aortic PWV and augmentation index. Expand
Sympathetic activation decreases medium-sized arterial compliance in humans.
TLDR
The results indicate that sympathetic activation is able to decrease radial arterial compliance in healthy subjects, and the reduction in arterial Compliance probably resulted from complex interactions between changes in distending blood pressure and changes in radial arterials smooth muscle tone.
