Implication
May aid early cardiomyopathy detection; leaves open prospective trials validating outcome benefit over conventional echocardiography.
Structured PICO
Does left ventricular strain and strain rate imaging improve the detection of subtle perturbations in contractility in patients with cardiomyopathy compared to conventional echocardiography?
P
Population
Patients with cardiomyopathy (CM)
I
Intervention
Left ventricular (LV) strain and strain rate (SR) imaging
C
Comparator
Conventional echocardiographic measures of ventricular function
O
Outcome
Detection of subtle perturbations in contractility and characterization of myocardial mechanicssurrogate
Strain and strain rate imaging provide a more precise characterization of myocardial mechanics than conventional echocardiography, aiding in the early diagnosis and management of cardiomyopathy.
