A higher BDI-II cognitive factor z-score was significantly associated with increased cardiac morbidity and mortality (adjusted HR 1.36; 95% CI 1.02-1.82; p=0.04).

Is the BDI-II cognitive factor associated with cardiac morbidity and mortality in patients after coronary artery bypass graft?
A cognitive depression factor marked by pessimism, past failure, self-criticalness and worthlessness is associated with increased cardiac morbidity and mortality after coronary artery bypass graft.
Hazard Ratio: 1.36 (95% CI 1.02–1.82)
p-value: p=.04
This study examined the Beck Depression Inventory-II (BDI-II) with Confirmatory Factor Analysis and followed up cardiac morbidity and mortality for a median of 4.9 years among 226 coronary artery bypass graft patients. Cardiac morbidity and mortality events (n = 65, 28.8%) were associated with BDI-II cognitive factor z-score (adjusted hazard ratio = 1.36, 95% confidence interval 1.02 - 1.82, p = .04), controlling for left ventricular impairment, age, respiratory disease, heart failure, renal disease and diabetes. A cognitive depression factor marked by pessimism, past failure, self-criticalness and worthlessness was consistently associated with cardiac morbidity and mortality, contrasting to other work.
Tully et al. (2011) conducted a cohort in Coronary artery bypass graft (n=226). BDI-II cognitive factor z-score was evaluated on Cardiac morbidity and mortality (adjusted HR 1.36, 95% CI 1.02 - 1.82, p=.04). A higher BDI-II cognitive factor z-score was significantly associated with increased cardiac morbidity and mortality (adjusted HR 1.36; 95% CI 1.02-1.82; p=0.04).
