Platelet-activating factor, also known as PAF, PAF-acether or AGEPC (acetyl-glyceryl-ether-phosphorylcholine), is a potent phospholipid activator and mediator of many leukocyte functions, platelet aggregation and degranulation, inflammation, and anaphylaxis.
Heart failure with preserved ejection fraction (HFpEF) is a form of heart failure in which the ejection fraction – the percentage of the volume of blood ejected from the left ventricle with each heartbeat divided by the volume of blood when the left ventricle is maximally filled – is normal, defined as greater than 50%; [1] this may be measured by echocardiography or cardiac catheterization.
Lipoprotein-associated phospholipase A 2 (Lp-PLA 2) also known as platelet-activating factor acetylhydrolase (PAF-AH) is a phospholipase A 2 enzyme that in humans is encoded by the PLA2G7 gene. [5] [6] Lp-PLA 2 is a 45-kDa protein of 441 amino acids. [7] It is one of several PAF acetylhydrolases.
The platelet-activating factor receptor (PAF-R) is a G-protein coupled receptor which binds platelet-activating factor. [ 5 ] [ 6 ] It is encoded in the human by the PTAFR gene . The PAF receptor shows structural characteristics of the rhodopsin (MIM 180380) gene family and binds platelet-activating factor (PAF).

Pronunciation follows convention outside the medical field, in which acronyms are generally pronounced as if they were a word (JAMA, SIDS), initialisms are generally pronounced as individual letters (DNA, SSRI), and abbreviations generally use the expansion (soln. = "solution", sup. = "superior").
This is a list of abbreviations used in medical prescriptions, including hospital orders (the patient-directed part of which is referred to as sig codes).This list does not include abbreviations for pharmaceuticals or drug name suffixes such as CD, CR, ER, XT (See Time release technology § List of abbreviations for those).
