The association between long-term blood pressure patterns in community-dwelling adults and risk of intracerebral hemorrhage and cerebral infarction is not well-characterized. This prospective study included 79,385 participants, free of stroke, myocardial infarction and cancer in or prior to 2010(baseline). Systolic blood pressure trajectories were identified using latent mixture modeling with data from 2006, 2008 and 2010. Incident cases of intracerebral hemorrhage and cerebral infarction occurred during 2010 to 2014, confirmed by review of medical records, by three physicians. We identified 5 distinct systolic blood pressure trajectories during 2006 to 2010. Each of the trajectories was labelled according to their blood pressure range and pattern over time: normotensive-stable(n=26,740), prehypertension-stable(n=35,674), stage 1 hypertension-increasing(n=8,215), stage 1 hypertension-decreasing(n=6,422), and stage 2 hypertension-stable(n=2,334). We documented 1,034 incident cases of cerebral infarction and 187 cases of intracerebral hemorrhage. Although the prehypertension-stable trajectory exhibited systolic blood pressure range within the “normal” range(120–140 mmHg) during 2006 to 2010, this group had higher stroke risk relative to the normotensive-stable group(<120 mmHg) (adjusted hazard ratio was 3.11 for intracerebral hemorrhage and 1.99 for cerebral infarction; P<0.001 for both), after adjusting for possible confounders. Individuals in the stage 2 hypertension-stable systolic blood pressure trajectory (175–179 mmHg) had the highest risk of intracerebral hemorrhage(adjusted hazard ratio was 12.4) and cerebral infarction (adjusted hazard ratio was 5.07), relative to the normotensive-stable group(P<0.001 for both). Blood pressure trajectories were associated with the risk of stroke and increasing blood pressure trajectories within the currently designated “normal” range may still increase the risk for stroke.
