[Risk stratification in atherosclerotic coronary disease]. / Estratificación de riesgo en la enfermedad coronaria aterosclerosa.

In this article we present some concepts expressed at the lecture on Risk Stratification in Coronary Artery Disease, presented during the course offered by the National Institute of Cardiology "Ignacio Chávez" in October 5-7, 2000, under the name of Cardiology 2000. This paper deals mainly with the importance of coronary risk factors and how to evaluate risks in patients with stable or unstable angina and in myocardial infarction.

[Myocardial infarction related to the association of physical exertion and the ingestion of cold drinks]. / Infarto del miocardio relacionado a la asociación de esfuerzo y la ingesta de bebida fría.

We describe 3 young individuals with acute myocardial infarction that developed after extenous stress followed by the intake of cold fluids. The patients had retrosternal chest pain and EKG changes suggestive of posterior-inferior myocardial infarction. Coronartiography demonstrated 40% and 50% narrowing of the right coronary artery. The remaining case had normal coronary arteries.

[Myocardial infarct secondary to a non-penetrating chest injury. Presentation of a case and review of the literature]. / Infarto miocárdico secundario a traumatismo no penetrante del tórax. Presentación de un caso y revisión de la literatura.

We describe a 21 year old male who had a myocardial infarction as a result of a horse kick in the chest. EKG Showed changes compatible with anterolateral infarction. Thallium scan demonstrated diffuse decreased uptake. Angiographic studied showed normal coronary arteries and abnormal movements of the posterior wall.
