Implication
Normal LV volumes typify most DHF; extends pathophysiological synthesis for clinicians while leaving open targeted trials on coupling and deformation.
Key Points
- To review the pathophysiology and cardiac functional characteristics of diastolic heart failure, focusing on systolic properties, ventricular-arterial coupling, and diastolic performance.
- Synthesized findings from clinical studies evaluating left ventricular morphology, conductance catheter hemodynamic data, and advanced imaging modalities.
- Evaluated diagnostic criteria established by the European Society of Cardiology alongside studies investigating myocardial deformation, twist mechanics, and contractile reserve.
- Left ventricular dimensions and end-diastolic volumes are normal in approximately 90% of patients with diastolic heart failure, while wall thickness and mass are typically increased.
- Diagnostic criteria require an ejection fraction >45%, a left ventricular end-diastolic volume index <97 mL/m², signs and symptoms of heart failure, and verified diastolic abnormalities.
- Pathophysiological impairment in diastolic heart failure encompasses abnormal relaxation and filling dynamics, impaired ventricular-arterial coupling, and subtle alterations in deformation mechanics.
