- Abstract
This study examined the contribution of biomedical and psychological variables in the report of anginal frequency at 6-week, 6- and 12-month follow-up in patients who received angioplasty with and without stent. Patients (N = 70) completed a battery of standardized questionnaries, including measures of depression, anxiety, and anger. Principal components analysis computed a single factor of negative emotion for use as a predictor in regression analyses. For the 6-week model, only baseline anginal frequency predicted anginal freqency. Negative emotion joined baseline anginal frequency in the prediction model for 6-month anginal frequency, and collectively accounted for 23% of the variance. For the 12-month model, baseline anginal frequency, female sex, and negative emotions remained in the model, accounting for 46% of the variance in anginal frequency. These results highlight the importance of biomedical and psychosocial variables in predicting anginal frequency with psychological variables sustaining predictive value over the course of recovery.
