"Strain and strain rate (SR) are measures of deformation that reflect left ventricular (LV) function. To our knowledge, no previous study described these indexes in a general population," investigators in Louvain, Belgium report (see also Cardiology).
"We therefore described peak-systolic strain and SR of the LV in the general population and derived diagnostic thresholds for these measurements in a healthy subgroup. In 480 subjects enrolled in a family-based population study (50.5% women; mean age, 50.5 years; 37.2% hypertensive), we measured: (i) end-systolic longitudinal strain and peak-systolic SR from the basal portion of the LV inferior and inferolateral free walls; (ii) radial deformation of the LV inferolateral wall. Longitudinal (mean, 22.9%) and radial (59.2%) strain and longitudinal (1.31 s(-1)) and radial (3.40 s(-1)) SR decreased with age (P
The researchers concluded: "Our current study resulted in the proposal for diagnostic thresholds for strain and SR, based on a healthy subgroup recruited via random sampling of the population."
Kuznetsova and colleagues published their study in European Heart Journal (Left ventricular strain and strain rate in a general population. European Heart Journal, 2008;29(16):2014-2023).
