Age, left ventricular fractional shortening
, left ventricular end diastolic volume, longer symptoms time, hypertension and medications like ACE inhibitors or ARBs were associated with AKI occurrence.
Phillips & Harkin (2003) diagnosed hypothyroidism and cardiac failure in two dogs, whose echocardiographic findings were similar to those documented in subjects diagnosed with dilated cardiomyopathy, including diminished fractional shortening
and augmented left ventricular internal diameters in systole and diastole.
An enlarged left atrium and/or right ventricle, declining left ventricle fractional shortening
rate and an elevated amount of brain natriuretic peptides were all associated with the occurrence of PAH.
Left ventricular systolic function was taken as LVEF and fractional shortening
HF--heart failure, LVEF--left ventricular ejection fraction, LVFS--left ventricular fractional shortening
, NT-proBNP--N terminal-probrain natriuretic peptide, TNF-[alpha]--tumor necrosis factor-alpha Table 2.
Left ventricular fractional shortening
was calculated by the following formula: [left ventricular-end diastolic diameter (LVDD)--left ventricular-end systolic diameter x 100]/LVDD.
Additionally, left ventricular percentage fractional shortening
was calculated as a synthetic index of left ventricular systolic function .
On baseline or diagnostic echo, left ventricular ejection fraction and fractional shortening
were statistically significant predictors of clinical outcome (p<0.
(FS) and ejection fraction (EF) (by Teichholz>s formula) were also calculated.

One use of echocardiography is calculating the fractional shortening
index of the heart that is used in veterinary and there is a standard model for the estimation of it [3,4,8,22].
