New diagnostic perspectives on heart failure with preserved ejection fraction: systolic function beyond ejection fraction
Todaro MC, Khandheria BK, Longobardo L, et al. New diagnostic perspectives on heart failure with preserved ejection fraction: systolic function beyond ejection fraction. J Cardiovasc Med. 2014 Dec 2. [epub ahead of print].
Although preserved ejection fraction is found in more than 50% of patients with heart failure, its acceptance as a specific clinical entity is limited. More understanding of the physiopathology, early diagnosis and medical management is needed. With no existing systematic information in the literature, the aim of this review is to provide a comprehensive overview of the new imaging techniques for diagnosing heart failure with preserved ejection fraction, particularly in the early stages of the disease, underlying the pivotal role of new technologies such as two-dimensional speckle tracking echocardiography and vascular stiffness.
