Left ventricular longitudinal strain is a major determinant of CT-derived three-dimensional maximum principal strain: comparison with two-dimensional speckle tracking echocardiography

This work reviews the reasons why the characteristics of left ventricular (LV) contractility, in particular, and 2D speckle echocardiography-based peak rates of global longitudinal strain (GLS), are not widely used in clinical practice. Authors present the analysis of new indicators proposed for the assessment ofLVcontractile function based on longitudinal strain taking into account the involvement of individual segments. The authors show that the assessment of myocardial work indicators characterizing the relationships between contractile and pump functions is a promising approach for the study ofLVcontractile function. The analysis of postsystolic strain index (PSI) is presented to illustrate its clinical implementation in the studies of viable myocardium in ischemic conditions and evaluating the effectiveness of cardiac resynchronization therapy (CRT).

Background: The purpose of the present study was to assess whether systemic arterial hypertension is associated with abnormal right ventricular (RV) structure and function as assessed by three-dimensional speckle tracking echocardiography and how those changes are related to left ventricular (LV) strain, left ventricular hypertrophy (LVH) and aortic (Ao) function. Methods: We examined 115 hypertensive (mean age, 65±16 years; 52% male) and 115 healthy adults (mean age, 68±13 years; 54% male). Patients were divided into two groups: patients with LVH (Group I, LVMI>115g/m 2 men, LVMI>95g/m 2 women) and patients without LVH (group II). LV longitudinal (LS), circumferential, radial and area (GAS) strains were calculated by three-dimensional speckle tracking echocardiography (3DSTE). RV free-wall longitudinal strain (LS) was determined by 3DSTE. Aortic (Ao) distensibility and stiffness index (SI) were calculated using accepted formulae. The corrected aortic strain (Ao-S) by two-dimensional speckle tracking echocardiography was calculated as the global aortic strain /pulse pressure. Data analysis was performed offline (GE EchoPAC). Results: Overall, Ao-SI was increased (r=0.74, p=0.003) and Ao-S was decreased (r=0.79, p=0.002) in hypertensive patients compared with controls. Ao-SI had a negative correlation with Ao-S (r=-0.76, p<0.001). Ao-S correlated with LV and RV longitudinal strain (r=0.62,p=0.02, and r=0.58,p<0.05, respectively) and LV and RV area strain (r=0.66,p=<0.01, and r=0.53,p<0.05, respectively). RV-LS and LV-GAS were lower in Group 1 patients compared to Group 2 (r=0.81, p<0.001), and lower in Group 2 patients compared to controls (r=0.59, p=0.02). There was a positive correlation between LV and RV LS (r=0.52, p<0.05). RV-LS was independently associated with Ao-S (β=0.37, p=0.01), LV-GAS (β=0.32, p=0.027) and LV-LS (β=0.26, p=0.034) in the whole hypertensive population. Conclusions: In systemic hypertension there is a complex interaction between LV strain, RV strain and Ao strain. Reduced RV strain can occur even in the absence of LV hypertrophy.
