title: [Assessment of the state of atrial myocardium by two-dimensional grey-scale deformation in patients with arterial hypertension and mild left ventricular hypertrophy].
abstract: Non-Doppler two-dimensional grey-scale deformation (TGD) is a novel method of assessment of deformation and velocity of deformation of myocardium. TGD allows to evaluate regional and global mechanical function of atria. Aim of our work was to study longitudinal deformation and deformation velocity of the left atrium (LA) and right atrium (RA) in patients with arterial hypertension (AH) and mild left ventricular hypertrophy (LVH). We carried out standard transthoracic echocardiography with subsequent analysis by the TGD method in 30 patients with 1st degree AH and mild LVH. The following measurements were done: maximal longitudinal deformation and maximal velocity of deformation during atrial contractile, reservoir, and conduit phases. We also measured global maximal deformation of LA during its contractile, and reservoir phases. Results of the study showed that changes of parameters of deformation of atrial myocardium developed in patients and mild LVH. Changes of parameters of deformation of LA myocardium were observed in reservoir and conduit phases manifesting as reduced deformation and deformation velocity. Patients with AH and mild LVH had no significant changes of parameters of deformation of atrial myocardium in their contraction phase. Further investigations are required for understanding changes of deformation occurring in myocardium of atria.
