AIM: Studies investigating the relationship between pulse pressure (PP) and prognosis in acute ischemic stroke remain limited. Thus, in this study, we aim to determine whether changes in PP in the early phase of ischemic stroke are associated with neurological deterioration or stroke recurrence.
METHODS: Patients who participated in the Acute Aspirin Plus Cilostazol Dual Therapy for Non-cardiogenic Stroke Patients Within 48 Hours of Symptom Onset (ADS) trial were included in this study. We then divided the patients into four groups (low-low, low-high, high-low, high-high) according to low or high PP both on admission and 24 h after admission. The threshold PP calculated by receiver operating characteristic curve analysis of PP on admission for neurological deterioration within 14 days and recurrent ischemic stroke/transient ischemic attack (TIA) within 3 months was 69 mmHg.
RESULTS: Neurological deterioration within 14 days was observed in 118 patients (10.6%), whereas recurrent ischemic stroke/TIA within 3 months was noted in 34 patients (3.2%). Among these four groups, both neurological deterioration within 14 days (odds ratio [OR] 2.09, 95% confidence interval [CI] 1.12-3.91; p=0.0209) and recurrent ischemic stroke/TIA within 3 months (OR 4.80; 95% CI 1.62-14.86; p=0.0064) were significantly more frequent in the high-high group than in the low-low group as per the results of our multivariate analysis. In addition, neurological deterioration within 14 days was significantly higher in the high-low group than that in the low-low group (OR 2.70; 95% CI 1.44-5.05; p=0.0019).
CONCLUSIONS: High PP during the acute phase of ischemic stroke appears to be associated with ischemic stroke recurrence and neurological deterioration, particularly if PP is elevated both on admission and 24 h later after admission.
