There are several well-recognized medical dictionaries and dictionaries of acronyms used in medical literature in the library's print and electronic book collections which will help you correctly interpret terms and acronyms. You can find a complete list in our online catalog by searching "medical dictionary". The resources cited below are eBooks which you can access via the library website from on or off campus.
According to Jablonski's dictionary of medical acronyms & abbreviations [electronic resource] (6th ed.) (2009), the acronym "LAD" can refer to:
"lactic acid dehydrogenase; laser-assisted drug delivery; left anterior descending [coronary artery]; left atrial defect; left axis deviation; leukocyte adhesion deficiency; leukocyte antibody detection assay; ligament augmentation device; linoleic acid depression; lipoamide dehydrogenase; lymphocyte-activating determinant"
The highlighted terminology would be most relevant to heart disease, particularly ischemia. If you scan the entries which begin "LAD" you will see several other related acronyms and terms.
This anatomical structure is also known in Latin as "ramus interventricularis anterior arteriae coronariae sinistrae" (Dorland's Illustrated Medical Dictionary (31st ed.) (2007).
In a related question, you inquire about "ICD criteria". Jablonski's defines ICD as, inter alia, "implantable cardioverter defibrillator."
Lastly, your questions reference "ejection fraction" assessment. The definition found in Webster's new world medical dictionary [electronic resource] (3rd ed.) (2008) is:
The percentage of blood that is pumped out of a filled ventricle as a result of a heartbeat. The heart does not eject all the blood in the ventricle. Only about two-thirds of the blood is normally pumped out with each beat, and that fraction is referred to as the ejection fraction. The ejection fraction is an indicator of the heart’s health. If the heart is diseased from a heart attack or another heart condition, the ejection fraction may decrease.
[See related LibAnswers question concerning "impaired LV systolic" for substantive application of these terms.]
