“Global Left Ventricular Myocardial Work Efficiency in Healthy Individuals and Patients with Cardiovascular Disease”
CME Information: 1 credit
Release date: September 2019 Valid through: September 2020
Introduction/Statement of Need:
Global left ventricular (LV) myocardial work efﬁciency, the ratio of constructive to wasted work in all LV segments, reﬂects the efﬁciency by which mechanical energy is expended during the cardiac cycle. Global LV myocardial work efﬁciency can be derived from LV pressure-strain loop analysis incorporating both noninvasively estimated blood pressure recordings and echocardiographic strain data. The aim of this study was to characterize global LV myocardial work efﬁciency in healthy individuals and patients with cardio-vascular (CV) risk factors or overt cardiac disease.
This activity is designed for all cardiac sonographers and cardiovascular physicians with a primary interest and knowledge base in the field of echocardiography; in addition, residents, researchers, clinicians, intensivists, and other medical professionals.
At the end of this article the reader will better be able to:
Consider the application of the noninvasive evaluation of myocardial work to the assessment of global LV function
Better appreciate the characteristics of global myocardial work efficiency in healthy individuals and those with heart disease
Describe methodology for the quantification of global LV myocardial work efficiency
