Controllability and hemodynamic reaction patterns during mental stress

Hemodynamic parameters during a perioperative vancomycin reaction.

Hemodynamic and sympathoadrenal responses to mental stress during nitric oxide synthesis inhibition.

Cardiovascular and sympathoadrenal responses to a reproducible mental stress test were investigated in eight healthy young men before and during intravenous infusion of the nitric oxide (NO) synthesis inhibitor N-monomethyl-L-arginine (L-NMMA). Before L-NMMA, stress responses included significant increases in heart rate, mean arterial pressure, and cardiac output (CO) and decreases in systemic ...

Socioeconomic status and hemodynamic recovery from mental stress.

We assessed the changes in cardiac index and total peripheral resistance underlying blood pressure reactions and recovery from acute mental stress, in relation to socioeconomic status. A sample of 200 men and women aged 47-59 years was divided on the basis of occupation into higher, intermediate, and lower socioeconomic status groups. Blood pressure was monitored using the Portapres, and hemody...

Vestibulosympathetic reflex during mental stress.

Increases in sympathetic neural activity occur independently with either vestibular or mental stimulation, but it is unknown whether sympathetic activation is additive or inhibitive when both stressors are combined. The purpose of the present study was to investigate the combined effects of vestibular and mental stimulation on sympathetic neural activation and arterial pressure in humans. Muscl...

Evaluation of mental health and posttraumatic stress disorder in Iranian medical students during outbreak COVID-19
