What explains difference in heart rate recovery among those of varying levels of socioeconomic status?

Harvard Pop Center Director Lisa Berkman and colleagues, including recent visiting scientist Cathal McCrory, are authors on a paper published in The Journals of Gerontology Series A that links higher levels of educational attainment with better heart rate recovery, which is an important biomarker of cardiovascular health and predictor of mortality. Lifetime smoking was found to play a significant role in explaining some of the differences between the educational levels.
