Development and Validation of a Prediction Model and Score for Transthyretin Cardiac Amyloidosis Diagnosis: T-Amylo.

Background: Although transthyretin cardiac amyloidosis (ATTR-CA) is often underdiagnosed, clinical suspicion is essential for early diagnosis.

Objectives: The aim of this study was to develop and validate a feasible prediction model and score to facilitate the diagnosis of ATTR-CA.

Methods: This retrospective multicenter study enrolled consecutive patients who underwent Tc-DPD scintigraphy for suspected ATTR-CA.

Influence of Cardiovascular Risk in the Prediction and Timing of Cardiac Events After Exercise Echocardiogram Testing Without Ischemia.

Introduction And Objectives: There have been no analyses of the influence of cardiovascular risk as a predictor of events in patients with exercise echocardiography (EE) without ischemia. Our objective was to determine the predictors of cardiac events, paying special attention to cardiovascular risk.

Methods: This study included 1640 patients with EE without ischemia.
