Tissue Doppler imaging reveals that LV strain and strain rate decrease with age and obesity, allowing for the establishment of diagnostic thresholds in a healthy population.
We explored the early signs of LV systolic dysfunction in a general population, using tissue Doppler imaging technique. LV strain and SR decrease with age, body weight, central obesity, and RWT. 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 et al. (Thu,) studied this question.
