Systolic blood pressure was strongly associated with incident stroke, increasing the risk by approximately 25% for each 10 mm Hg increase.
Cohort (n=37,655)
Does increased systolic and diastolic blood pressure increase the risk of incident stroke in an urban Chinese population?
Systolic blood pressure is a stronger risk factor for stroke than diastolic blood pressure, with a 25% increased risk per 10 mm Hg increase in systolic BP.
Effect estimate: 25% increase per 10 mm Hg
As part of a longitudinal study performed in urban China, 37,655 subjects were evaluated for stroke risk factors, including having their blood pressure measured in a standard fashion. The cohort was followed for 3.5 years during which time 427 subjects experienced incident strokes--221 ischemic, 203 hemorrhagic, and 3 undefined. Both systolic and diastolic blood pressure were significantly related to risk of stroke and stroke type. Associations were stronger for systolic than diastolic blood pressure. These results emphasize the importance of systolic blood pressure, as opposed to diastolic, as a risk factor for stroke. In this study, the risk of stroke is increased by about 25% with each 10 mm Hg increase in systolic blood pressure.
Fang et al. (Mon,) conducted a cohort in Stroke (n=37,655). Blood pressure was evaluated on Incident strokes (25% increase per 10 mm Hg). Systolic blood pressure was strongly associated with incident stroke, increasing the risk by approximately 25% for each 10 mm Hg increase.
