Usefulness of strain rate imaging in detecting ischemic myocardium during dobutamine stress

Tissue Doppler echocardiography in ischemic heart disease - the diagnostic potential for predicting the ischemic substrate and myocardial viability

“…Nárůst SR vykazuje bifázický průběh podle dávky dobutaminu. (16) Redukované jsou i hodnoty εs, ale vzhledem k objevení se εps se celkově u ischemických segmentů εmax zřetelně nesnižuje. (17) Pouhé měření absolutních vrcholových hodnot ε a SR se ale zatím nezdá být velkým přínosem v detekci ischemie při dobutaminové echokardiografii.…”

Quality Assurance of Segmental Strain Values Provided by Commercial 2-D Speckle Tracking Echocardiography Using in Silico Models: A Report from the EACVI-ASE Strain Standardization Task Force

“…Since, several thousand articles have been published about speckle tracking echocardiography (STE), with increasing impact on clinical management of patients in cardiology. In these studies, typical patterns of differing segmental strain curves in the left ventricle have been described for the assessment of acute and chronic ischemic heart disease (Stoylen, et al 2000, Hanekom, et al 2005, Miyasaka, et al 2005, Grenne, et al 2010, different forms of ventricular hypertrophy (Cikes, et al 2010), storage diseases (Phelan, et al 2012), cardiomyopathies (Haugaa, et al 2012), transplant rejection (Marciniak, et al 2007), cardiac dyssynchrony (Parsai, et al 2009) congenital heart disease (Friedberg and Mertens 2009) and risk evaluation for cardiac arrhythmias (Haugaa, et al 2012) to name a few. At present, two-dimensional (2D) STE is implemented on most ultrasound systems and has become the most frequently used tool for non-invasive assessment of regional myocardial function.…”
