The use of coronary revascularization among patients with myocardial infarction varies by race/ethnicity and socioeconomic status. The objective of this study was to determine whether local availability of facilities might influence apparent racial disparities in revascularization and health outcomes. ⋯ Race and socioeconomic factors influence the likelihood of revascularization after myocardial infarction among residents of New York City. In addition, lack of availability of revascularization further reduces its use by residents of disadvantaged neighborhoods.

Aging is associated with increased production of catabolic cytokines, reduced circulating levels of insulin-like growth factor 1 (IGF-1), and acceleration of sarcopenia (loss of muscle with age). We hypothesized that these factors are independently linked to mortality in community-dwelling older persons. ⋯ Greater levels or production of the catabolic cytokines TNF-alpha and interleukin 6 are associated with increased mortality in community-dwelling elderly adults, whereas IGF-1 levels had the opposite effect.
