Abstract

Accurate identification of the presence of acute myocardial infarction in adult patients who present to the emergency department with anterior chest pain remains elusive. The artificial neural network is a powerful nonlinear statistical paradigm for the recognition of complex patterns, with the ability to maintain accuracy when some data required for network function are missing. Earlier studies revealed that the artificial neural network is able to accurately identify acute myocardial infarction in patients experiencing chest pain. However, these studies did not measure network performance in real time, when a significant amount of data required for network function may not be available. They also did not use chemical cardiac marker data. Two thousand two hundred four adult patients presenting to the ED with anterior chest pain were used to train an artificial neural network to recognize the presence of acute myocardial infarction. Only data available at the time of initial patient evaluation were used to replicate the conditions of real-time patient evaluation. Forty variables from patient histories, physical examinations, ECG results, and chemical cardiac marker determinations were used to train and then test the network. Th...Continue Reading
