Quantifying and predicting recovery after heart surgery.
The validity of the biopsychosocial approach to the study of health and illness is reaffirmed by the prospective findings of the Recovery Study. This is a multidisciplinary examination, conducted in four teaching hospitals, of the predictors of symptoms of cardiac illness in 463 patients 6 months after coronary artery bypass or cardiac valve surgery. We found that the following preoperative measures predict freedom from cardiac symptoms 6 months after surgery: low levels of all of the following: angina pain, shortness of breath, fatigue and sleep problems, lifetime cigarette usage, and preoperative hospitalization for cardiac treatment; low levels of anxiety, depression, and hostility, and few life change events; high levels of all of the following: self-esteem, well-being, vigor; prevalence of activities and hobbies, social participation, and social support. The six variables in bold print contributed independently in a multiple regression equation that accounted for 21% of the variance of the symptoms score and was associated with an estimated 45% difference in success of recovery. The statistical strength and general nature of many of the predictors indicate that the predictors may also be important in recovery from other health crises. Psychosocial and biomedical factors correlate across time (predictively), as well as cross-sectionally, indicating that psychological, social, and biological mechanisms may be parts of a single general multifaceted process influencing recovery of health. A clinical trial could determine if psychological, social, or behavioral interventions will hasten and improve recovery from physical illness or trauma.
