Short-term blood pressure changes have a more strong impact on stroke and its subtypes than long-term blood pressure changes.

ABSTRACT:

Background

Elevated blood pressure (BP) is closely related to stroke and its subtypes. However, different time periods changes in BP may result in differential risk of stroke.

Hypothesis

Short-term blood pressure changes have a more strong impact on stroke and its subtypes than long-term blood pressure changes.

Methods

We designed the study on the effects of short- (2008-2010) and long-term (2004-2010) BP changes on stroke events (2011-2017), including 22 842 and 28 456 subjects, respectively. The difference in β coefficients between short- and long-term BP changes on the effects of stroke were examined using the Fisher Z test.

Results

During a median 12.5-year follow-up period, 1014 and 1505 strokes occurred in short- and long-term groups. In short-term group,
