Abstract 3154: Interacton of Left Ventricular Geometry and Cardiovascular Hemodynamics in 57,307 Patients wth Preserved Ejection Fraction
We and others have demonstrated the prognostic impact of LV geometry on subsequent survival in patients with preserved ejection. The purpose of this investigation was to describe parameters of cardiovascular hemodynamics and energetics associated with normal and abnormal LV geometry, including concentric remodeling (CR), eccentric hypertrophy (EH), and concentric hypertrophy (CH) fraction in patients who were referred for routine echocardiographic evaluation. Measures were obtained using standard non-invasive methods previously reported. Survival was obtained by the National Death Index after a mean follow-up of 2.8 years.
Conclusion: Changes in LV geometry are associated with significant abnormalities in cardiac and vascular hemodynamics and energetics that in general progress from CR to frank hypertrophy. Intervention directed towards modifying these parameters are needed in order to evaluate the potential for improving clinical outcomes.
