Why the study?
Does good control of hypertension reduce the incidence of stroke in treated hypertensive patients compared to fair or poor control?
Does good control of hypertension reduce the incidence of stroke in treated hypertensive patients compared to fair or poor control?
Adequate control of hypertension (diastolic BP < 100 mmHg) significantly reduces the incidence of stroke, independent of the initial severity of blood pressure elevation.
Good control associated with lower stroke incidence in this cohort; supports risk-reduction efforts but leaves causality and practice change open.
Summary The incidence of stroke in a group of 499 treated hypertensive patients was closely related to the adequacy of control of hypertension. This trend was independent of the level of diastolic blood pressure at presentation, and differed markedly from the incidence of myocardial infarction and angina pectoris which did not vary with adequacy of control.
