Higher admission blood pressure (BP) among patients with a transient ischemic attack (TIA) is associated with improved in-hospital, 30-day, and 90-day post-discharge outcomes, a new study found. Patients in the US national Get With the Guidelines-Stroke registry with a TIA were included. Post-discharge 30-day and 90-day outcomes of interest were mortality, readmission for stroke, and readmission for major cardiovascular event (MACE). Among the details:
- Among the 218,803 patients with TIA, lower admission systolic blood pressure (SBP) was associated with worse in-hospital outcomes.
- Compared with patients with SBP of 150 mm Hg, a lower SBP of 120 mm Hg was associated with higher risk of in-hospital death, not being discharged home, or inability to ambulate independently at discharge.
- Similarly, among the 64,352 patients in the CMS-linked cohort, an inverse association between SBP and post-discharge mortality and MACE was observed to 30- and 90-days post-discharge.
