Capacity for direct attention in patients undergoing percutaneous coronary intervention: the effects of psychological...

Emphasis is placed on educating coronary heart disease patients about lifestyle choices to reduce the risk of further cardiovascular events, but little attention has been paid to the impact of attentional capacity on patients' learning. The purpose of this study is to identify and compare the capacity for direct attention and the effect of psychological distress during hospitalization and 6 weeks after percutaneous coronary intervention. Forty subjects, mean age of 63 years, 27 men and 13 women, completed components of the Wechsler Memory Test to measure direct attention, and the Profile of Mood States. There were significant differences in the Digit Span Test-backward, a measure of working memory (t=-2.79; p<0.009), and the Profile of Mood States total score, a measure of psychological distress (t=3.183; p<0.003), from hospitalization to 6 weeks post-percutaneous coronary intervention. Data demonstrate psychological distress and reduced capacity for direct attention during hospitalization indicating that hospital environments are suboptimal for learning.
