Abstract

OBJECTIVE
To determine the time period and factors inhibiting recovery of orthostatic hypotension during head up tilt with ischemic stroke patients. METHOD: Fourty two ischemic stroke patients with orthostatic hypotension were included. Blood pressure and heart rate were taken after resting in the supine position for 10 minutes and again after standing for one minute every week. Age, gender, body mass index, laboratory findings, diabetes mellitus, anti-hypertensive use, side of involved hemisphere and K-MBI were obtained.
RESULTS
The numbers of orthostatic hypotension patients were significantly decreased at 3rd week. Non recovering group until 3rd week were older in age and had higher plasma creatinine level. On the other hand, body mass index and K-MBI were lower than the group without orthostatic hypotention. Multivariate analysis revealed that age, body mass index, anti-hypertensive medication were independently associated factors for resistant orthostatic hypotension during head up tilt.
CONCLUSION
For 7 weeks, especially at 3rd week, the numbers of orthostatic hypotension patients significantly decreased. Age, BMI, and antihypertensive medication were inhibitiing factors for recovery of orthostatic hypotension.
