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

Figure 2 Medication adherence (8-item Morisky Medication Adherence Scale) by psychological disorder subtype. Bar chart comparing mean 8-item Morisky Medication Adherence Scale scores across patient groups stratified by psychological disorder subtype (n = 330). Patients without psychological disorders demonstrated the highest medication adherence scores (mean 6.4 ± 1.4), while those with comorbid depression and anxiety showed the lowest (mean 4.5 ± 1.1). Other subgroups, including depression only, anxiety only, and adjustment disorder, exhibited intermediate adherence levels. Values represent mean ± SD. Psychological disorders were classified based on standardized assessments within 6 months after percutaneous coronary intervention. MMAS-8: 8-item Morisky Medication Adherence Scale.
