Coagulation activity before and after acute psychosocial stress increases with age.
OBJECTIVE To assess whether stress further increases hypercoagulation in older individuals. We investigated whether acute stress-induced changes in coagulation parameters differ with age. It is known that hypercoagulation occurs in response to acute stress and that a shift in hemostasis toward a hypercoagulability state occurs with age. However, it is not yet known whether acute stress further ...
متن کاملIndependent association between lower level of social support and higher coagulation activity before and after acute psychosocial stress.
OBJECTIVE To investigate the relationship between social support and coagulation parameter reactivity to mental stress in men and to determine if norepinephrine is involved. Lower social support is associated with higher basal coagulation activity and greater norepinephrine stress reactivity, which in turn, is linked with hypercoagulability. However, it is not known if low social support intera...
متن کاملHigher overcommitment to work is associated with lower norepinephrine secretion before and after acute psychosocial stress in men.
BACKGROUND Overcommitment (OC) is a pattern of excessive striving. In reaction to work stress, OC has been associated with higher sympathetic nervous system activation and cortisol release, but data on neuroendocrine reactivity to standardized stressors are scarce. We investigated whether OC is associated with differential levels of the stress hormones norepinephrine and cortisol in response to...
متن کاملCoronary vasoconstriction to endothelin-1 increases with age before and after ischaemia and reperfusion.
OBJECTIVE Ageing is known to be associated with changes within the heart. We investigated whether the coronary response to endothelin-1 (ET) and sarafotoxin S6c (S6c) is altered with increasing age, before and after cardioplegic arrest. METHODS Using an isolated rat heart model, increasing concentrations of ET and S6c were administered to rats of different ages (group I = one month; group II ...
متن کاملHPA Axis Activity under Psychosocial Stress in Patients with Acute and Remitted Panic Disorder
Background: Panic disorder (PD) has been linked to an altered activity of Hypothalamic-pituitary-adrenal (HPA) axis. To understand the elevated risk for future psychiatric episodes in PD it is of interest how remitted patients might differ from healthy controls in the activity of the HPA axis. Methods: Fourteen patients with PD and 14 healthy controls were exposed to the Trier Social Stress Tes...
