Prognostic Accuracy of the GRACE Score in Octogenarians and Nonagenarians with Acute Coronary Syndromes.

Background: The GRACE Score was derived and validated from a cohort in which octogenarians and nonagenarians were poorly represented.

Objective: To test the accuracy of the GRACE score in predicting in-hospital mortality of very elderly individuals with acute coronary syndromes (ACS).

Methods: Prospective observational study conducted in the intensive coronary care unit of a tertiary center from September 2011 to August 2016.

Accuracy of gestalt perception of acute chest pain in predicting coronary artery disease.

Aim: To test accuracy and reproducibility of gestalt to predict obstructive coronary artery disease (CAD) in patients with acute chest pain.

Methods: We studied individuals who were consecutively admitted to our Chest Pain Unit. At admission, investigators performed a standardized interview and recorded 14 chest pain features.
