简要总结
The purpose of this study is to determine whether Coronary Computed Tomographic Angiography (CCTA) will increase patient safety by decreasing the rate of missed ACS and adverse events in patients who receive standard care plus CCTA versus standard care alone. Additional goals of the study are to determine whether CCTA can safely reduce the duration of ED visits and the number and duration of hospital admissions.
详细描述
Justification:
Acute coronary syndrome (ACS) is the clinical manifestation of acute myocardial ischemia induced by coronary artery disease (CAD). Although most patients presenting with chest pain to the Emergency Department (ED) can be stratified into "high risk" or "low risk" chest pain algorithms, patients at "intermediate risk" are more difficult to manage. This translates into lengthy waits in the ED and repetitive investigations while 5.3% of cases of ACS are still missed and too many patients are admitted to the CCU (false positive rate of 14%). CCTA is a novel, non-invasive method for evaluating coronary artery stenosis and occlusion.
The ability to accurately diagnose or exclude ACS in patients in a rapid, non-invasive fashion has been previously lacking. If CCTA is shown to be clinically useful in risk stratification of this patient population, there is great potential for increasing patient safety, reducing ED admission times and decreasing the number and duration of CCU admission.
Objectives:
ED admission and discharge times, CCU consult and decision times and duration of CCU admission, cardiac risk factors, vital signs, laboratory results, ED disposition plan, CCTA results, coronary calcium score, index hospitalization diagnosis, investigations, revascularization rates as well as 30-day diagnosis, death, adverse event rate and subsequent investigations.
