Why the study?
Does low perceived social support increase the risk of death or recurrent MI in post-MI patients, and does psychosocial intervention improve these outcomes?

Key result
Baseline low perceived social support in post-MI patients was associated with a higher risk of death or nonfatal MI compared to patients without LPSS (23% vs 10%; HR 1.74-2.39).

LPSS identifies higher-risk post-MI patients; leaves open whether baseline-stratified psychosocial interventions improve outcomes.

Does low perceived social support increase the risk of death or recurrent MI in post-MI patients, and does psychosocial intervention improve these outcomes?
Effect estimate: HR 1.74-2.39
Absolute Event Rate: 23% vs 10%
Baseline low perceived social support is an independent predictor of death and recurrent MI in post-MI patients, and psychosocial intervention effects may depend on baseline support levels.
Burg et al. (2005) conducted a cohort in Post-myocardial infarction (n=1,911). Low perceived social support (LPSS) / Psychosocial intervention vs. No LPSS or depression (MI comparison group) was evaluated on Combined end point of death or nonfatal MI (HR 1.74-2.39). Baseline low perceived social support in post-MI patients was associated with a higher risk of death or nonfatal MI compared to patients without LPSS (23% vs 10%; HR 1.74-2.39).
