Blood pressure variability and prognosis in acute XXXX on the rostral ventrolateral medulla (RVLM).

@entity1 @entity64 @entity101 @entity2850 @entity385
One of the known causes of @entity101 is vascular compression on the rostral ventrolateral medulla (RVLM). However, it remains unknown whether @entity2850 causes the significant variability in blood pressure observed during acute @entity385 . The purpose of this study was to evaluate differences in blood pressure variability and prognosis in acute @entity385 @entity1 based on the presence or absence of @entity2850 . We evaluated 56 @entity1 with acute @entity385 . Blood pressure was measured every 6 h for 72 h after admission and evaluated with successive variation (SV). The presence of @entity2850 was evaluated using time-of-flight 3D magnetic resonance imaging. Neurological severity was evaluated using the National Institutes of Health @entity64 Scale (NIHSS) at admission and 14 days after admission, and clinical improvement was determined by taking the difference in the NIHSS scores between admission and at 14 days. @entity1 clinical outcome was evaluated with the modified Rankin scale on discharge. Vascular compression of the RVLM was identified in 15 @entity1 (26.8%). The proportion of @entity1 showing clinical improvement was significantly higher in the non-compression group (odds ratio, 0.21 (95% CI = 0.06-0.78); P = 0.01). The SV value for systolic blood pressure was significantly higher in the compression group (P < 0.0001). We found that @entity1 with @entity2850 had a greater variability in blood pressure during the acute @entity385 phase, which may be related to poorer prognosis.
