Analysis of the invasive strategy decision in patients with acute coronary syndrome without ST-segment elevation in a real-world setting.

Observational studies have reported a marked discrepancy between the risk estimated by scores and the use of an invasive strategy in patients with acute coronary syndromes. The objective is to describe the criteria used to decide an early invasive strategy and to determine the differences between those criteria and the thrombolysis in myocardial infarction risk score (TRS). Patients entered to the Epi-Cardio registry with a diagnosis of non-ST-elevation acute coronary syndrome were analyzed.
