Abstract 20047: Validation of the Simple Acute Coronary Syndrome (SACS) Score for Identifying Obstructive Coronary Artery Disease
Background: Each year, up to 136,000 individuals suffering from acute coronary syndrome (ACS) are misdiagnosed and discharged from our nations’ emergency departments. We developed the Simple Acute Coronary Syndrome (SACS) score that tabulates a patient’s symptoms, ECG findings, risk factors, and cardiac markers (Figure 1). Our aim was to validate this novel scoring tool in its ability to identify the presence of obstructive coronary artery disease (CAD).
Methods: A single-center retrospective chart review was performed after institutional review board approval. The charts of 42 consecutive patients who presented with ACS and who were treated with an invasive strategy were reviewed. Scores were calculated for each patient using the SACS tool as well as the Modified Thrombolysis in Myocardial Infarction (TIMI) ACS calculator. The study endpoint was the presence of at least one vessel obstructive CAD at cardiac catheterization. Descriptive statistics were employed.
Results: The stratification of SACS and Modified TIMI scores for each of the 42 ACS patients is shown in Figure 2. In patients with a SACS score that was less than 3, none of these patients were found to have obstructive CAD at cardiac catheterization. For patients with a SACS score of 4 or higher, 100% of these patients were shown to have obstructive CAD. For patients with Modified TIMI scores of 1 and 2, 3/11 (27%) were found to have obstructive CAD.
Conclusions: The novel SACS scoring system identifies ACS patients who will have obstructive CAD more reliably than more traditional scoring systems. The SACS scoring tool needs to be validated in larger scale studies.
