Key result
Poststroke diastolic blood pressure of 80-84 mm Hg was associated with a lower stroke recurrence rate (3.8% per patient-year) compared to lower (9.2%, P<0.05) and higher (11.4%, P<0.01) pressures.

Does poststroke blood pressure level affect stroke recurrence in hypertensive stroke patients?
Absolute Event Rate: 3.8% vs 9.2%
p-value: p=<0.05
Poststroke diastolic blood pressure exhibits a J-curve relationship with stroke recurrence, with the lowest recurrence rate observed at 80-84 mm Hg.
Irie et al. (1993) conducted a cohort in Stroke with a history of hypertension (n=368). Poststroke diastolic blood pressure 80-84 mm Hg vs. Lower and higher poststroke diastolic blood pressure was evaluated on Stroke recurrence rate (p=<0.05). Poststroke diastolic blood pressure of 80-84 mm Hg was associated with a lower stroke recurrence rate (3.8% per patient-year) compared to lower (9.2%, P<0.05) and higher (11.4%, P<0.01) pressures.
