“…A patient with new chest pain and a normal or notdiagnostic ECG had a probability of 6.6% Table III for AMI, comparable to the 10% for the gen eral population. The high specificity of pathological ECG tracings suggesting the presence of AMI, re peatedly reported [5,12,13,32,33], was stressed again in our study, with a 97.4% confirmation of the diagnosis in such cases.…”

“…The sensitivity of serial ECG recordings in diag nosis AMI among hospitalized patients var ies from 63% [12] to 82% [31] with an aver age of 73% [8]. The value of the emergency room ECG as a decision-making tool has been evaluated elsewhere [5]: only 63% of their AMI patients had pathological ECGs with signs of either infarction or ischemia when first seen, and their percentage of AMI patients with normal (7%), or with 'nonspe cific' T-wave changes (6%) was similar to ours. Furthermore, in a more recent study [17], only 60% of patients with AMI had emergency room ECG tracings interpreted as showing 'probable AMI'.…”

The Importance of Creatine Kinase Determination in Identifying Acute Myocardial Infarction among Patients Complaining of Chest Pain in an Emergency Room

et al. 1987

The contribution of serum creatine kinase (CK) levels to the diagnosis of acute myocardial infarction (AMI) in an emergency room was studied in 252 patients presenting with chest pain. Thirty percent were ultimately diagnosed as having AMI. The electrocardiogram (ECG) identified 66% of patients with AMI who were evaluated within 4 h of onset of symptoms; while CK serum levels were elevated in only 9%. Among patients evaluated more than 4 h after the onset of symptoms, the ECG was helpful in diagnosing AMI in only 36.6%, while serum CK levels were high in 63.4%. CK testing added significantly to the diagnosis of AMI in patients already studied by ECG. We suggest that determination of serum CK levels in the emergency room is of value in the evaluation of patients complaining of chest pain 4 or more hours after the onset of symptoms.
