This is a secondary data analysis of an existing dataset generated from The Healthy Behavior Trial, an NHLBI-funded randomized controlled trial that enrolled 660 post-coronary angioplasty patients between October 1999 and March 2001. This study employed a behavioral intervention to motivate PCI patients to adopt health behaviors in order to reduce major cardiac and neurologic morbidity and mortality. Patients in the experimental arm were told their estimated biologic age (calculated from the health risk assessment) and risk factors were presented in terms of "biologic age reduction" that could be achieved if a change was made in each health behavior area. Those in the control arm were provided with risk factors (also obtained from the health risk assessment) and told that changing each health behavior could "increase your lifespan."
