Introduction:

Segmental and longitudinal strains are excellent parameters for the quantification of myocardial contractility.

Objective:

To identify the values ​​of segmental and longitudinal strain in Cuban patients with sickle cell disease.

Material and Method:

A prospective descriptive study was conducted in 31 patients with sickle cell disease and 52 controls who attended the Institute of Cardiology and Cardiovascular Surgery between June 2017 and January 2018, to which segmental longitudinal strain was determined as study variable. The means between the two groups were compared using the Student's t-test; an analysis of variance (ANOVA) was performed with a posteriori Tukey test for p <0.05.

Results:

In the patients with sickle cell disease, the means of segmental strain were between -17,7±3,4% (p=0,0001*) and -28,6±4,1%(p=0,0005*) and -29,3±1,1%(p=<0,0002*) with all segments being homogeneous; in the control group they were between -19,3±2,9% (p=0,0001*) in general. Despite the means were the lowest in Cuban patients with sickle cell disease, they were within the normal range. The mean values ​​of global longitudinal strain ranged between -19.2 ± 3.3 and -25.2 ± 2.7, being more negative in the control group with respect to Cuban patients with sickle cell disease.

Conclusions:

The results obtained are the first of its type published in Cuba. The segmental and longitudinal strain in Cuban patients with sickle cell disease analyzed, which have significantly different results from those obtained in healthy individuals, but normal, coincide with those reported in the international literature.

Palabras clave : sickle cell disease; segmental strain; longitudinal strain.
