Long-term outcomes based on time-to-angioplasty in patients admitted with non-ST-segment elevation acute coronary syndromes.

Objective: We investigated the impact of the duration from hospital admission to coronary angiography on the outcome of patients admitted with non ST-segment elevation acute coronary syndromes (NSTE-ACS).

Background: Invasive risk stratification in patients with acute coronary syndromes (ACS) has been shown to improve outcome in contemporary studies. It is unclear whether early coronary angiography is better than initial medical therapy with later angiography.
