Impact of extracardiac vascular disease on acute prognosis in patients who undergo percutaneous coronary interventions (data from the Blue Cross & Blue Shield of Michigan Cardiovascular Consortium [BMC2]).

Extracardiac vascular disease is associated with an increased risk of in-hospital mortality and other complications after coronary interventions, independent from other co-morbidities and baseline characteristics. The underlying cause of this significant association is unclear, but it warrants further investigation in an attempt to improve outcome in this high-risk cohort.
