Implication

May aid classification of exercise intolerance; leaves open whether mechanism-specific therapies alter outcomes.

Key Points

To delineate the pathophysiology of primary diastolic failure and assess appropriate therapeutic strategies based on filling dynamics and relaxation mechanics.
Conceptual review synthesizing the pathophysiology of ventricular filling resistance, diastolic compliance, and systolic relaxation alterations.
Diastolic failure results from increased resistance to ventricular filling, causing an upward shift in the diastolic pressure-volume relation that drives exercise intolerance.
The syndrome is primarily caused by inappropriate tachycardia, decreased diastolic compliance, and impaired systolic relaxation distinct from delayed contraction.
Effective therapeutic management requires customized regimens including bradycardic, remodeling, and lusitropic pharmacological agents.

Brutsaert et al. (1993) conducted a review in Primary diastolic dysfunction or failure. Bradycardic, remodeling and lusitropic drugs was evaluated. Primary diastolic dysfunction results from increased resistance to ventricular filling, and optimal therapy depends on the disease type and phase, potentially including bradycardic, remodeling, and lusitropic drugs.
