Patient-Oriented Evidence That Matters
Tighter Blood Pressure Control Does Not Increase the Likelihood of Orthostatic Hypotension
Am Fam Physician. 2021 Aug ;104(2):208.
Are lower blood pressure goals associated with a higher likelihood of orthostatic hypotension?
Orthostatic hypotension, a drop of 20 mm Hg systolic or 10 mm Hg diastolic after moving from sitting to standing, was not associated with more intensive treatment of blood pressure and may be less likely to occur with intensive treatment. (Level of Evidence = 1a)
The authors assembled randomized trials from three databases, including Cochrane CENTRAL, that compared intensive goals with less intensive goals for blood pressure treatment. They included studies written in any language. Two investigators independently abstracted the articles and evaluated them for quality. All studies were open label, and there was a risk of detection bias because investigators were aware of the patients' treatments. The studies enrolled 18,466 patients. Intensive blood pressure treatment was associated with a lower risk for orthostatic hypotension, but not by much (odds ratio = 0.93; 95% CI, 0.86 to 0.99). The likelihood of orthostatic hypotension was not different with active treatment compared with placebo. The effect did not differ if the patient had (or did not have) orthostatic hypotension before randomization. The original studies did not evaluate for rates of lightheadedness, syncope, or falls.
