- Objective: An excessive cardiovascular response to acute stress is a probable risk factor for cardiovascular (CV) disease. Such reactivity is usually assessed from the CV response to laboratory stressors. However, if it is a risk factor, correlated responses must occur in real life. Design: In the present study, we investigated the relationship between the heart rate (HR) response to five laboratory stressors and HR reactivity in the field. Measures: HR variation, the response to a real life stressor (public speaking), and the increase in HR with periods of self-reported tense arousal. Ambulatory HR, activity and posture were measured continuously over a 7-hr period. Results: The HR increase to laboratory stressors did not relate to HR variation consistently, but it did relate to the other two field measures. Conclusion: The results suggested that a tendency to increased HR reactivity may be a risk factor for cardiovascular disease when combined with exposure to stress.
