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.

Incremental Prognostic Value of the Incorporation of Clinical Data Into Coronary Anatomy Data in Acute Coronary Syndromes: SYNTAX-GRACE Score.

Background: When performing coronary angiography in patients with acute coronary syndrome (ACS), the anatomical extent of coronary disease usually prevails in the prognostic reasoning. It has not yet been proven if clinical data should be accounted for in risk stratification together with anatomical data.

Objective: To test the hypothesis that clinical data increment the prognostic value of anatomical data in patients with ACS.

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.
