“Psychobiological factors of stress reactivity in essential hypertension”
Project leader: Petra Wirtz
Project duration: 2003 – 2005

Essential hypertension is considered one of the most important risk factors in the development of cardiovascular disease as well as the underlying process of arteriosclerosis. The mechanisms that cause hypertensive individuals to develop above-average levels of arteriosclerosis have not been fully uncovered.
The project investigated physiological stress reactivity in men with essential hypertension as well as control subjects with regular blood pressure. Besides stress hormones such as cortisol and catecholamine, we also recorded the clotting factor and blood lipids. A particular focus was placed on identifying psychological factors accompanying increased physiological stress reactivity. The results showed a general hyperreactivity of the examined physiological systems in subjects affected by essential hypertension. Besides reduced perceptions of social support and the poor regulation of emotions, psychological correlatives of increased physiological stress reactivity in hypertension also included adverse attributions of failure.
