Figure 3

Panel A shows the phase and corresponding residual blood flow velocity (BFVR) values at baseline, BFVR minimum and BFVR maximum for the right MCA for the normotensive -- and - -- hypertensive groups and for - O- the non-stroke side MCA in the stroke group. Panel B shows the phase and corresponding BFVR values for the left MCA in the normotensive and hypertensive groups and for the stroke side MCA in the stroke group. BFVR phase was significantly greater in the stroke and hypertensive groups compared to the normotensive group for BFVR minimum and maximum in both MCAs (between groups phase comparisons *** p < 0.005, ** p < 0.01). Panel C shows the phase and corresponding residual blood pressure (BPR) values for the BPR minimum and maximum (between groups BPR values comparisons +++ p < 0.001, mean ± SE).
