title: Diastolic dysfunction in the presence of left ventricular systolic dysfunction: implications of beta-adrenergic blocking therapy.
abstract: The contribution of left ventricular diastolic dysfunction to the impairment in overall left ventricular performance in patients with systolic dysfunction is underappreciated. This article summarizes the available data on diastolic dysfunction in patients with congestive heart failure in which the predominant abnormality was thought to be left ventricular systolic dysfunction. The prevalence and identification of diastolic abnormalities and their clinical relevance are addressed, particularly the role of beta-adrenergic blocking therapy. The potential benefits of beta-adrenergic blocking therapy to diastolic performance are discussed from both a hemodynamic and clinical standpoint, with the implication that diastolic performance and its modulation should be considered in future investigations.
