Beyond mean blood pressure levels, blood pressure variability (BPV) and autonomic nervous system imbalance, reflected by heart rate variability (HRV), have emerged as important predictors of cardiovascular risk. This study aimed to examine trajectory-based associations between a structured acupressure intervention, blood pressure variability, and autonomic balance in patients with primary hypertension.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Participants received either structured acupressure (12 sessions over 4 weeks) plus usual care or usual care alone. Blood pressure variability was assessed using 24-hour ambulatory monitoring. Autonomic balance was measured via heart rate variability indices. Linear mixed-effects models estimated longitudinal trajectories. Mediation was tested using structural equation modelling.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Compared with controls, the intervention group showed greater reductions in systolic blood pressure variability (\n                      <jats:italic>\u03b2<\/jats:italic>\n                      \u2009=\u2009\u22121.92, 95% CI \u22122.78 to \u22121.06,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&amp;lt;\u2009.001).

Exploratory mediation analysis identified a significant indirect association, suggesting that changes in autonomic balance may partially account for the observed relationship.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Structured acupressure was associated with favorable longitudinal changes in blood pressure variability and autonomic function compared with usual care. Mediation analysis suggested that changes in autonomic balance may partially account for the observed association; however, these findings should be interpreted cautiously because the quasi-experimental design does not allow causal inference.
