BACKGROUND AND OBJECTIVE: We analyzed the diagnostic utility of a chest pain score in patients evaluated for chest pain of possible coronary origin.
PATIENTS AND METHOD: We studied 1,068 consecutive patients coming to the emergency room with acute chest pain of possible coronary origin without ST-segment elevation, using a chest pain unit protocol. Chest pain was quantified by validated score (0-20 points). The diagnostic value of the chest pain score was analyzed for the diagnosis of acute myocardial infarction (AMI), unstable angina (UA) and acute coronary syndrome (ACS; AMI or UA).
RESULTS: The diagnosis of ACS was established in 651 patients (61%), AMI in 439 (41%) and UA in 212 (20%). In the multivariate analysis a chest pain score > or = 10 was an independent predictor of ACS (odds ratio [OR] = 2.9; 95% confidence interval [CI] 2.1-4; p = 0.0001), along with an age older than 70 years (OR = 2.6; 95% CI,1.8-3.7; p = 0.0001), male gender (OR = 2; 95% CI, 1.4-2.8; p = 0.0001); insulin-dependent diabetes (OR = 2.3; 95% CI, 1.2-4.6; p = 0.016); previous myocardial infarction (OR = 1.6; 95% CI, 1.1-2.4; p = 0.022), ST depression (OR = 9.3; 95% CI, 5.2-16.7; p = 0.0001) and T wave inversion (OR = 2.5; 95% CI, 1.4-4.3; p = 0.0001). The chest pain score was associated with the diagnosis of both AMI (OR = 1.4; 95% CI, 1.1-1.9; p < 0.02) and UA (OR = 2.8; 95% CI, 1.8-4.2; p < 0.0001).
CONCLUSIONS: The chest pain score allows independent information for the early diagnosis of patients coming to the emergency department with acute chest pain of possible coronary origin.
