Global longitudinal strain was lower than the 5th percentile in 44% of the subjects with any rheumatic heart disease (p=0.002 versus controls) and 57% of the subjects with definite rheumatic heart disease (p=0.03). The mean absolute strain values were significantly lower when comparing subjects with any rheumatic heart disease with controls (20.4\u00b13.95 versus 22.4\u00b14.35, p=0.025) and subjects with definite rheumatic heart disease with controls (19.9\u00b14.25 versus 22.4\u00b14.35, p=0.033).<\/jats:p><\/jats:sec><jats:sec id=\"S1047951116002778_abs5\" sec-type=\"conclusion\"><jats:title>Conclusion<\/jats:title><jats:p>Global longitudinal strain is decreased in subjects with rheumatic heart disease in the absence of abnormal systolic function.
