Figure 2. Mean Blood Pressure after 3-min standing in patients with and without orthostatic hypotension and with and without orthostatic symptoms.
Patients with symptoms had a significantly lower MBP standing than those with symptoms, regardless of the presence of OH (p<0.001). In the vast majority of patients, symptoms appeared when MBP<75 mmHg (denoted with a horizontal dashed line and shaded area). (60.1±10.5 mmHg vs. 89.5±12.3 mmHg in the 20/10 group; 58.4±10.1 mmHg vs. 90.3±11.1 mmHg in the 30/15 group).
