Tissue Doppler Imaging as an Independent Prognosticator of Mortality: Insights from Copenhagen Study

This presentation discusses the findings of the Fourth Copenhagen City Heart Study (2002-2007), illustrating the prognostic significance of echocardiographic tissue Doppler imaging in predicting overall mortality within the general population. It reveals that low values of systolic and diastolic parameters provide valuable insights, even when conventional echocardiographic results appear normal. The study indicates that tissue Doppler imaging enhances prognostic accuracy, emphasizing its potential role in clinical practice for early heart failure detection and management.
