Psychological Burden and Psychosocial Stress in Younger and Middle-Aged Women with Prior Myocardial Infarction.

Background and

Objectives

Younger and middle-aged women may continue to describe psychological and psychosocial burden years after myocardial infarction (MI), yet multicenter real-world data remain limited on what women retrospectively report during long-term follow-up. This study examined such reports in younger and middle-aged women with prior MI while explicitly accounting for delayed, heterogeneous follow-up timing and the non-standardized nature of symptom ascertainment. Materials and

Methods

We performed a cross-sectional analysis within a Croatian multicenter cohort of 957 women younger than 60 years hospitalized with STEMI or NSTEMI between 1 February 2020 and 28 February 2025. Psychological information was collected retrospectively during routine follow-up; the formal PHQ-4 instrument was not administered. A study-specific four-item summary informed by PHQ-4 content was described, and exploratory multivariable analyses modelled this summary as a continuous variable. Descriptive timing-stratified sensitivity analyses and a timing-restricted continuous-score sensitivity model were additionally performed.

Results

Prior psychiatric diagnosis was recorded in 16.0% of women, post-MI psychiatric diagnosis in 31.4%, and any psychosocial stressor in 73.2%. Among women with complete item responses, the four-item summary showed a broad distribution rather than a discrete threshold pattern. In continuous-score analyses, higher observed summary values were associated with younger age, prior psychiatric diagnosis, any psychosocial stressor, non-partnered status, non-employment, pregnancy complications/adverse pregnancy outcomes, and greater peri-menopausal symptom burden. Median summary values were only modestly higher in the small ≤ 1-year stratum and were otherwise similar across the later follow-up strata. Higher summary values were also associated with lower odds of self-reported regular current statin-based lipid-lowering use.

Conclusions

These findings are best interpreted as exploratory data on retrospectively reported and currently endorsed long-term psychological and psychosocial burden years after MI, not as contemporaneous measures of recovery-phase psychopathology. Prospective studies with predefined assessment windows and validated instruments are needed.
