Analogy tests and psychopathology at follow-up after open heart surgery.
A study of 100 coronary bypass and cardiac valvular surgery patients investigated whether preoperative brain damage, as measured by the Conceptual Level Analogy Test (CLAT), is a major risk factor for postoperative psychiatric symptoms and mortality. Three cognitive psychological tests, including the CLAT, and psychatric interviews were given preoperatively, postoperatively, and at 18-month follow-up. ⋯ However, long-term outcome was unrelated to medical diagnosis and only weakly related to surgical procedure, but highly significantly related to preoperative analogy scores. The CLAT was a more consistent predictor of both short- and long-term outcome than any of the other ten variables considered (medical and surgical variables, inhospital outcome, demographic measures, other psychological tests).
