Asymptomatic Left Ventricular Diastolic Dysfunction: Predicting Progression to Symptomatic Heart Failure

Asymptomatic left ventricular diastolic dysfunction (ALVDD) (diastolic abnormalities and normal ejection fraction in the absence of symptoms) is associated with incident heart failure (HF) and decreased survival. Abnormalities of diastolic function might therefore be included in the definition of stage B HF, which denotes individuals at risk for the development of HF. Imaging techniques, especially echocardiography, are necessary for the recognition of preclinical left ventricular (LV) diastolic disturbances, as well as further tracking of pathological changes and responses to treatment. The transition of ALVDD to symptomatic HF is underlain by multiple factors, including both cardiovascular and noncardiovascular determinants. The initiation of management strategies targeting cardiovascular and systemic comorbidities in patients identified as having ALVDD may delay symptomatic progression and improve prognosis.
