Abstract

MORA, Guillermo et al. Clinical and electrocardiographic characteristics of patients admitted to a thoracic pain unit in the context of a new definition of acute myocardial infarction. Rev. Col. Cardiol. [online]. 2005, vol.11, n.7, pp.333-343. ISSN 0120-5633.

In our environment we do ignore the clinical and paraclinical characteristics from patients who come to a thoracic pain unit and more so with the new definition of acute myocardial infarction (AMI). Material and methods: 398 patients admitted to a thoracic pain unit were prospectively evaluated as to the pain characteristics, its risk factors, clinical examination findings, electrocardiographic findings and the troponin T behaviour. Results: 29.4% of the patients had a diagnosis of AMI, 29.9% of unstable angina and 40.7% of non-ischemic thoracic pain. Retrosternal pain, irradiation to the neck, presence of diaphoresis, nausea or vomit are related with a higher probability to the diagnosis of AMI. Male sex and the presence of risk factors such as diabetes or dislipidemia increase the probability of the diagnosis. In the electrocardiogram, only the presence of a lesion, especially subepicardical favors the diagnosis. Unstable angina and in general acute coronary syndrome have a similar although not equal clinical behaviour.

Keywords : thoracic pain; acute myocardial infarction; unstable angina.
