myocardial work
Advanced echocardiographic parameter that assesses myocardial performance by incorporating afterload in strain analysis.
Full Definition
Myocardial work represents a novel non-invasive method for evaluating cardiac function that combines speckle tracking strain imaging with blood pressure measurements to estimate the work performed by the left ventricle. This technique provides four key parameters: global work index, global constructive work, global wasted work, and global work efficiency. By incorporating afterload into the analysis, myocardial work offers superior assessment of myocardial performance compared to strain alone, particularly useful in detecting subtle ischemia and monitoring treatment response.
Usage
Usage note: Requires simultaneous blood pressure measurement during strain imaging; specify which work parameters are being reported.
