Plain-English summary
A group of 17 cats with hypertrophic cardiomyopathy (HCM), a heart condition that can cause breathing problems and lethargy, were studied to assess how well their left atrium (a part of the heart) was functioning compared to 20 healthy cats. Researchers used a special imaging technique called two-dimensional speckle tracking echocardiography to measure heart function. They found that the left atrial function was significantly lower in the HCM cats than in the healthy ones. This method proved to be reliable for evaluating heart function in cats with HCM, which could help veterinarians monitor and manage this condition more effectively.

Abstract
BACKGROUND: Left atrial (LA) function plays an important role in diastolic dysfunction in cats with hypertrophic cardiomyopathy (HCM). Two-dimensional speckle tracking echocardiography (2D-STE) is a technique for assessing LA function. This study aimed to evaluate the LA function in HCM cats compared to normal cats, using 2D-STE. RESULTS: Seventeen client-owned cats affected with HCM and twenty healthy control cats were studied. Conventional echocardiographic and 2D-STE variables were measured and compared between groups (control and HCM groups). Variability of the peak atrial longitudinal strain (PALS) displayed good reproducibility with 4.7% intra-observer and 14% inter-observer repeatability. The mean value of PALS in the HCM group (13.16 ± 8.64) was lower than that in the control group (28.54 ± 10.31) (P < 0.001). PALS was lowest in the LA roof region. The atrial longitudinal strains of septal and lateral regions were significantly lower in the HCM group than in the normal group. The PALS correlated with the percentage of the LA fractional shortening (LA-FS) (r = 0.538, P = 0.001), the percentage of the LA ejection fraction (LA-EF) (r = 0.797, P < 0.001), and the LA fractional area change (FAC) (r = 0.746, P < 0.001). CONCLUSIONS: PALS is a feasible and reproducible method to evaluate the LA function in cats affected with HCM.
