A Multivariate Model for Prediction of Obstructive Coronary Disease in Patients with Acute Chest Pain: Development and Validation.

Background:: Currently, there is no validated multivariate model to predict probability of obstructive coronary disease in patients with acute chest pain.

Objective:: To develop and validate a multivariate model to predict coronary artery disease (CAD) based on variables assessed at admission to the coronary care unit (CCU) due to acute chest pain.

Methods:: A total of 470 patients were studied, 370 utilized as the derivation sample and the subsequent 100 patients as the validation sample.
