Prediction of functional and psychological status after percutaneous transluminal coronary angioplasty.
OBJECTIVE
To examine symptom, functional status, and psychological status profiles after percutaneous transluminal coronary angioplasty (PTCA) and determine indicators of outcome.


METHODS
Descriptive and correlational with repeated measures.


METHODS
Hospital or home (2.1 days before PTCA) and home (3.9 and 10.2 months after discharge).


METHODS
Self-administered questionnaires (developed for study) for functional status (personal and instrumental activities of daily living), and cardiac symptoms (chest pain and shortness of breath at rest and on exertion). General Health Questionnaire(16) for psychological status.


METHODS
One hundred thirty with PTCA (mean age 57 years, 84% male, 15% with prior PTCA).


RESULTS
Chest pain and shortness of breath at rest and on exertion decreased and functional and psychological status improved 3.9 months after PTCA, with measures maintained at 10.2 months. At 3.9 months after PTCA, poorer psychological status was predicted by having had a longer duration of coronary artery disease before PTCA. Post-PTCA indicators of poor psychological status were continued chest pain and shortness of breath on exertion and not working. The presence of post-PTCA chest pain on exertion and not working were also correlated with reduced functional status.


CONCLUSIONS
Although pre-PTCA variables such as duration of coronary artery disease can predict post-PTCA outcome, the use of variables measured after PTCA may also provide clinicians with accurate estimates of functional and psychological status after PTCA.
