Zhong Y, et al. - The proposition analyzed was that stroke distance was correlated with five-year all-cause mortality, independently of other echocardiography variables, and that stroke distance added long-term prognostic value. Eligible candidates included consecutive elderly patients, over 65 years of age and mean 79·9 ± 7·1 years, hospitalized due to heart failure. A connection was unveiled between stroke distance with long-term mortality, independently of other known echocardiographic prognostic factors in elderly patients hospitalized with heart failure. Left ventricular ejection fraction (LVEF) appeared to be related to mortality only when stroke distance was excluded from analysis. It was discovered that stroke distance had additive prognostic value.
