Clinical Trial Summary

Study aims and hypotheses are as follows: Primary Hypotheses: Compared to the neutral condition, the anger recall task will acutely induce endothelial dysfunction by impairing endothelium-dependent arterial vasodilation (Hypothesis 1a); increasing circulating levels of EC-derived microparticles (EMPs), a marker of EC injury (Hypothesis 1b); and reducing circulating levels of bone marrow-derived endothelial progenitor cells (EPCs), a marker of EC reparative capacity (Hypothesis 1c). Secondary Hypotheses: Compared to the neutral condition, the depressed mood and separately the anxiety recall tasks will acutely impair endothelium-dependent arterial vasodilation, increase circulating levels of EMPs, and reduce circulating levels of bone marrow-derived EPCs. There will be a relation of the level of self-reported anger, depressed mood, and anxiety with endothelial dysfunction.

Intervention

Other:
Anger Induction
The participant is asked to recall an incident in the recent past during which they became moderately to extremely angry, or is asked to read statements out loud evoking moderate to extreme feelings of anger. The participant is asked to take a few moments to bring the details of the incident to mind and, when ready, to describe the incident in great detail to the experimenter. Participants are asked to describe key elements, such as any dialogue that transpired during the incident, along with other details of the incident, particularly regarding the feelings of that particular emotion experienced at the time. In so doing, the experimenter works to re-elicit the emotions that accompanied the original incident. The duration of the negative emotion induction task is 8 minutes.
Depressed Mood Induction
The participant will be asked to undergo a validated depression/sadness induction task.
Anxiety Induction
The participant will be asked to undergo a validated anxiety induction task.
Neutral emotion task
This is a neutral control task that each of the negation emotion induction tasks will be compared to.
