Post-percutaneous coronary intervention psychological disorders predict poor adherence and cardiovascular events in elderly heart failure patients

Figure 3 Correlation between psychological symptom severity and medication adherence (8-item Morisky Medication Adherence Scale score). A: Scatterplot showing the relationship between depression severity, measured by Patient Health Questionnaire-9 score, and 8-item Morisky Medication Adherence Scale (MMAS-8 score) among patients with psychological disorders (n = 132). A significant inverse correlation was observed (r = -0.43, P < 0.001), indicating that higher depressive symptom burden was associated with poorer adherence; B: Scatterplot showing the relationship between anxiety severity, measured by Generalized Anxiety Disorder-7 score, and medication adherence (MMAS-8 score) in the same cohort. A similar negative correlation was found (r = -0.39, P < 0.001), supporting the impact of anxiety symptoms on treatment adherence behavior. Both correlations were estimated using Pearson’s correlation method. Patients were included only if psychological disorder was confirmed within 6 months post- percutaneous coronary intervention. MMAS-8: 8-item Morisky Medication Adherence Scale; PHQ-9: Patient Health Questionnaire-9; GAD-7: Generalized Anxiety Disorder-7.
