To assess the prognostic value of minor myocardial damage in patients presenting with chest pain without myocardial infarction. ⋯ Troponin T was the only marker that predicted future events, but a documented history of coronary artery disease was the best predictor in patients in whom an acute myocardial infarction had been ruled out.

Randomized Controlled Trial Clinical Trial
Early continuous ST segment monitoring in unstable angina: prognostic value additional to the clinical characteristics and the admission electrocardiogram.
In unstable angina, clinical characteristics, resting electrocardiography, and early continuous ST segment monitoring have been individually reported to identify subgroups at increased risk of adverse outcome. It is not known, however, whether continuous ST monitoring provides additional prognostic information in such a setting. ⋯ Patients with unstable angina and a normal admission ECG have a good prognosis, while ST segment depression predicts an adverse outcome. Transient myocardial ischaemia detected by continuous ST segment monitoring in such patients receiving optimal medical treatment provides prognostic information additional to that gleaned from the clinical characteristics or the admission ECG.

Comparative Study
Usefulness of transthoracic and transoesophageal echocardiography in recognition and management of cardiovascular injuries after blunt chest trauma.
To assess the diagnostic potential of transthoracic and transoesophageal echocardiography for the detection of traumatic cardiovascular injuries in patients suffering from severe blunt chest trauma. ⋯ Transthoracic echocardiography has low diagnostic yield in severe blunt chest trauma, while transoesophageal echocardiography provides accurate diagnosis in a short time at the bedside, is inexpensive, minimally invasive, and does not interfere with other diagnostic or therapeutic procedures.
