Stress and hypertension

Abstract

In susceptible persons emotional stress results in immediate sympathetic stimulation, with a vasomotor response that results in a high-output state and elevated blood pressure; the vasopressor response seems to be transient. There seems to be no longitudinal epidemiologic validation of the attractive hypothesis that transiently elevated blood pressures are the prelude to fixed hypertension, however. The acquisition of hypertension by populations abandoning their traditional mode of living has been attributed to the sociocultural stress inherent in westernization, but these studies usually have not taken into account concomitants of this type of acculturation, such as dietary changes and increased body weight. The inverse relationship of blood pressure levels to education could explain the development of hypertension when aspiration to upward mobility is thwarted. The severity of perceived occupational stress relates inversely to blood pressure, suggesting that familiarity with a job renders the demands made by the work environment more predictable and less threatening in terms of vasopressor response.
