title: Deliberations on Diastolic Heart Failure.
abstract: Studies of left ventricular diastolic dysfunction and diastolic heart failure (DHF), published during the past 4 decades, include a prodigious number and wide variety of research efforts. This review report considers some of the historical literature and incorporates more recent information supporting the idea that patients with DHF constitute a subgroup of the heterogeneous population of patients with heart failure and a preserved ejection fraction. Clinical investigation, particularly therapeutic trials, should be directed at specific targets within the population of interest, not at the broad heart failure with preserved ejection fraction population. To accomplish this, it is important to stipulate criteria for the diagnosis of DHF and to limit our attention to specific subgroups or phenotypes.
