Relation of life events to blood pressure control in the SHEP pilot trial

The Systolic Hypertension in the Elderly (SHEP) pilot trial was a five-center study in which 551 persons aged 60 years or older with isolated systolic hypertension were given antihypertensive drugs or placebos in order to determine the effects on blood pressure control and possible side effects of therapy. A life events inventory was administered to the cohort one year into the study. Results of this inventory were then compared to blood pressure and changes in blood pressure in the placebo and active therapy groups. One or more of the life events assessed were present in about 65% of the population. Although the sample was too small to detect very subtle effects, there was no evidence in this study that either individual or groups of life events play a major role in blood pressure regulation of persons with isolated systolic hypertension.
