Why the study?
Do depressive symptoms and social support influence the risk of sudden cardiac death in post-MI patients after controlling for fatigue?
Do depressive symptoms and social support influence the risk of sudden cardiac death in post-MI patients after controlling for fatigue?
The association between depression and sudden cardiac death after myocardial infarction is partially confounded by cardiac-related fatigue, though cognitive-affective depressive symptoms and social participation still contribute to mortality risk.
No takes yet. Share an insight, caveat, or question.
Fatigue may confound the depression-SCD link post-MI; leaves open distinct roles for fatigue versus residual depressive symptoms in risk stratification.
Irvine et al. (1999) studied this question.
