Does coronary bypass surgery have a different incidence of psychiatric complications compared to cardiac valvular surgery?
Does coronary bypass surgery have a different incidence of psychiatric complications compared to cardiac valvular surgery?
Psychiatric complications are significantly less common following coronary bypass surgery compared to cardiac valvular surgery.
Psychiatric symptoms less common after bypass than valvular surgery; observational data leave open causal effects versus selection bias.
Previous studies of psychiatric complications following open heart surgery have included few if any patients who had coronary bypass surgery. This experiment reports the relative incidence of psychiatric complications in a sample of 97 open heart surgery patients of whom 51 patients (53 per cent) had coronary bypass surgery. The results suggest that the incidence of psychiatric symptoms following coronary bypass surgery is significantly lower (16 per cent) than that following cardiac valvular surgery (41 per cent). Several possible reasons for this large discrepancy in incidence of psychiatric complications are considered.
