ALB and myocardial infarction: One of the early studies was performed in patients serially followed after acute myocardial infarction; a sustained and prolonged decrease of total T3 and fT3 was described, while total T4 but not fT4 showed a transient decrease; thyroxine binding globulin (TBG) levels remained unchanged, while thyroxine-binding pre-albumin (TBPA) and albumin exhibited a prolonged fall.
