Key result
Family systems-based case management reduces MACE risk ~73% vs routine care in high-risk patients.
Why the study?
A case management plan for patients at high risk of sudden cardiac death based on family systems theory had not been developed or clinically evaluated.
Does a family systems theory-based case management plan improve disease cognition, psychological well-being, family function, and reduce MACE in patients at high risk of sudden cardiac death?

Does a family systems theory-based case management plan improve disease cognition, psychological well-being, family function, and reduce MACE in patients at high risk of sudden cardiac death?
A family systems theory-based case management program significantly improves psychological well-being, disease cognition, family functioning, and reduces adverse cardiac events in patients at high risk for sudden cardiac death.

Supports family systems case management for high-risk SCD patients; extends limited RCT evidence to MACE reduction.
Objective To develop a case management plan for patients at high risk of sudden cardiac death (SCD) from the perspective of family systems theory and evaluate its clinical practice effects. Methods By using the random sampling method, 100 patients at high risk of SCD who visited our hospital from March 2025 to June 2025 were selected as the research subjects. They were randomly divided into an experimental group ( n = 50) and a control group ( n = 50). The control group received routine care and follow-up, while the experimental group implemented a case management plan based on the family systems theory, with both interventions lasting for one year. Both groups were evaluated at baseline and endpoint using disease cognition assessments, the Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder-7 (GAD-7), Tampa Scale for Kinesiophobia Heart (TSK-SV Heart), General Self-Efficacy Scale (GSES), Family APGAR, and Major Adverse Cardiac Events (MACE). Results There were no statistically significant differences in baseline data between the two groups ( P > 0.05). After the intervention, the experimental group showed significantly better scores in disease cognition, PHQ-9, GAD-7, TSK-SV Heart, GSES, APGAR, and MACE compared to the control group ( P < 0.05). Conclusion The case management plan for high-risk SCD patients based on family systems theory is scientifically sound and feasible. It can effectively reduce anxiety and depression, alleviate kinesiophobia, improve disease cognition, and promote family care, thereby improving the patients’ quality of life and prognosis.

Liu et al. (2026) conducted an RCT in High risk of sudden cardiac death (SCD) (n=100). Case management plan based on family systems theory vs. Routine care and follow-up was evaluated on Major Adverse Cardiac Events (MACE) (OR 0.270, 95% CI 0.093-0.783, p=0.016). A case management plan based on family systems theory significantly reduced the risk of major adverse cardiac events compared to routine care in patients at high risk for sudden cardiac death (OR 0.270).
