Abstract
OBJECTIVES
To identify the factors associated with early cardiac catheterization in patients with a non ST-segment elevation acute coronary syndrome.
METHODS
We analyzed data collected by retrospective chart review for 208 patients presenting at seven French hospitals with an acute coronary syndrome (chest pain at rest within 24 h prior to presentation with positive cardiac markers and/or electrocardiographic changes) between January and March 2005.
RESULTS
Eighty-seven patients (42%) were first admitted to hospitals with cardiac catheterization facilities. One hundred ten patients (53%, 95% confidence interval [95% CI], 46-60) underwent early cardiac catheterization less than 48 h following presentation. In addition to presentation at hospitals with catheterization facilities, factors independently associated with early catheterization included positive cardiac markers in patients first admitted to hospitals without catheterization facilities (adjusted odds ratio [aOR] 34.5, 95% CI, 4.4-268.0) and diabetes mellitus (aOR, 0.4, 95%CI, 0.2-0.9). With the exception of positive cardiac markers, no risk factors comprising the TIMI risk score were associated with increased odds of early cardiac catheterization. During the index hospital stay, six patients (3%) died, seven patients (3%) had pulmonary edema, three patients (1%) had major or minor bleeding, and none had ST segment elevation myocardial infarction.
CONCLUSION
Despite the dissemination of international guidelines, the use of early cardiac catheterization remains related to initial presentation at hospitals with catheterization facilities rather than risk assessment in patients with a non ST-segment elevation acute coronary syndrome.
