• W2049798371 abstract "Objective Heart failure is associated with poor prognosis and the differentiation of patients on the basis of diastolic filling patterns helps to identify several groups of patients with incrementally higher risk. However, this is reliant on accurate definition of filling patterns. The aim of this study was to compare preload reduction with contrast-enhanced pulmonary venous Doppler recordings for the correct assessment of diastolic filling pattern. Methods In all, 20 patients with heart failure and 25 healthy volunteers were studied on 2 separate days. Preload reduction was achieved with the Valsalva maneuver (nonstandardized and standardized) and sublingual nitroglycerin. Responses were compared among the 3 methods and the filling patterns obtained on each day with the various methods compared. Results Although pulmonary venous Doppler improved the diastolic classification over mitral Doppler, preload reduction resulted in better classification and improved sensitivity, specificity, and positive and negative predictive values. No advantage was observed for either the standardized Valsalva or pharmacologic preload reduction. Conclusion Preload reduction is an essential part of the assessment of diastolic filling grade in patients with heart failure as it can identify pseudonormal filling (mildly increased filling pressures), reversible restrictive filling (high filling pressures), and nonreversible restrictive filling pattern (very high filling pressures).
