• W2783158698 abstract "Summary Purpose Reduced blood circulation is an important feature of heart failure, and Doppler stroke distance of the left ventricular outflow tract is a measure of forward stroke volume. Several echocardiographic parameters have known prognostic implications in heart failure, but the prognostic implications of stroke distance in relation to other parameters are insufficiently known. The aim was therefore to test the hypothesis that stroke distance is associated with five‐year all‐cause mortality, independently of other echocardiography variables, and that stroke distance has added long‐term prognostic value. Methods A cohort of 350 consecutive elderly patients, over 65 years of age and mean 79·9 ± 7·1 years, hospitalized due to heart failure was studied. Patients with available echocardiography were included and images evaluated. Stroke distance was measured by tracing the systolic velocity time integral ( VTI ) of the pulsed wave Doppler in the left ventricular outflow tract. Other parameters were also estimated, such as left ventricular ejection fraction ( LVEF ), left ventricular mass, left atrial volume, early diastolic mitral velocity ( E ), deceleration time and mitral annulus tissue Doppler diastolic velocity ( e ′) and pulmonary artery systolic pressure ( PASP ). Results Five‐year all‐cause mortality, assessed without missing data, was 67·7%. Multivariate analysis showed that stroke distance, E / e ′ and PASP were independently associated with mortality, but LVEF was not. Conclusions Stroke distance was associated with long‐term mortality, independently of other known echocardiographic prognostic factors in elderly patients hospitalized with heart failure. Only when stroke distance was excluded from analysis, LVEF became associated with mortality. Stroke distance had additive prognostic value." @default.
