Key result
Left ventricular end-diastolic pressure is influenced by multiple factors such as heart rate, preload, and afterload, which must be considered when using it to evaluate left ventricular function.

Review
Clinicians must interpret LVEDP cautiously accounting for heart rate and loading conditions; leaves open refined load-independent LV function metrics for research.
There are several factors that could affect the left ventricular end-diastolic pressure. These include heart rate, preload, afterload, pericardial or pleural pressure, diastolic properties of the ventricle, and the left ventricular inotropic state. Recognition of these factors appears important when considering the left ventricular end-diastolic pressure as an index of left ventricular function.
