Abstract |
Objective To determine risk factors of orthostatic hypotension in ischemic stroke patients. Method In 98 ischemic stroke patients, blood pressure and heart rate were measured after resting in the supine position for 10 minutes and again after standing for one minute. Presence of orthostatic hypotension was correlated with age, gender, body mass index, laboratory findings, diabetes mellitus, anti-hypertensive use, side of involved hemisphere, smoking and K-MBI (Korean Modified Barthel Index). Results 30 out of 98 patients had orthostatic hypotension. Those patients with orthostatic hypotension were older in age and had a higher average blood pressure, heart rate and plasma creatinine. On the other hand, body mass index, K-MBI and serum sodium levels were lower in the orthostatic hypotension group. Multivariate analysis revealed that age, body mass index, anti-hypertensive use and smoking were independently associated with orthostatic hypotension. Conclusion Old age, low BMI, anti-hypertensive use, smoking were risk factors of orthostatic hypotension in the ischemic stroke patients. Patients in the higher risk categories should receive regular monitoring of blood pressure in order to detect orthostatic hypotension and prevent its complications.
