Cuyco HFpEF Flashcards
Predominant pathophysiologic cause of HFpEF?
Abnormal diastolic function (relaxation and stiffness)
LVEF diagnostic criteria for HFpEF?
> 50%
LVEDVI diagnostic criteria for HFpEF?
<97 ml/m2
LVEDP diagnostic criteria for HFpEF
> 16 mmHg
PCWP of HFpEF patients?
E/E’?
12 mmHg
E/E’ >15 or >8 + NT-proBNP >220 pg/ml
This coresponds to the period beginning at the end of the ventricular ejection (closure of semilunar valves) extending to the closure of the AV valves?
Diastole or ventricular filling
Diastolic function is influenced by what factors?
Myocardial relaxation
ventricular filling
Ventricle’s passive elastic properties
Heart rate
Parameters of diastolic function
Ventricular relaxation
Myocardial chamber compliance
Filling pressure
Classification of diastolic filling abnormalities
Abnormal relaxation
Restrictive physiology
Pseudonormalisation
A transition from abnormal relaxation to restrictive physiology
Decreased LV compliance+ moderate increase in LA pressure + abnormal relaxation profile
Pseudonormalisation
Maneuver that can unmask abnormal relaxation by reducing LA pressure
Valsalva - adequate if 10% reduction in the maximal E velocity is achieved
An increase in the size of this chamber signifies chronic diastolic dysfunction?
Left atrium
