Study Summary
The current study is designed to have broad generalizability and inform a potential shift toward greater utilization of stress echocardiography with UCA. This will be accomplished by comparing UCA stress echocardiography with myocardial SPECT among hospitalized patients presenting with atraumatic chest pain. This study seeks to demonstrate: clinical comparability of the 2 modalities (based on non-diagnostic test rates), improved care efficiency (based on length of stay), lower costs, improved provider satisfaction, and a presumed improved safety profile through the elimination of radiation exposure. Primary Hypothesis: A strategy of routine UCA (Optison™) enhanced stress echocardiography will result in a clinically non-diagnostic test rate comparable to myocardial SPECT among patients hospitalized (inpatient or hospital observation status) with atraumatic chest pain.
Primary Outcome
Non-diagnostic test rates will be the principal outcome of interest and are defined as those studies that do not allow a clinical decision for patient disposition (alternative non-invasive modality ordered, imaging inadequate to exclude ischemia, target heart rate not achieved, adverse side effects and test was terminated, discharge, further invasive testing such as coronary angiography) or require cardiology consultation for further evaluation.
Interventions
- OTHER UCA stress echocardiography or myocardial SPECT
