[|AI|]  Hello. I have gone through your query. Thanks for using Chat Doctor. Basically heart attack and Myocardial infarction are synonymous. It is a condition where there is total blockage of one of the three coronaries supplying blood to heart. There is total cut off of blood supply to particular segment of myocardium which results into necrosis that is death of tissue. Congestive cardiac failure is term to denote failing function of ventricles. Mainly when right ventricle fails, and it produces edema, ascites,neck vein engorgement and hepatomegaly. This is known as CCF. My best wishes Chat Doctor.
