Myo means muscle and Cardial relates to heart. My educated guess would be that it is a damage in one of the cells in your heart muscle.
Stretching a myocardial cell allows more Ca+2 into the cell and increases the force of contraction (the longer the muscle fiber when it begins to contract, the greater the force of contraction).

The cell membrane is the barrier between the cell and the outside environment.
Series of pathologic changes due to excessive stress when adaptations are not possible.

Actin
Neurones in the CNS and cardiac/myocardial cells.
myosin?
It means "something" to do with the heart's muscle.

I believe you are referring to STEMI (ST segment elevation myocardial infarction) and non-STEMI. These are two different forms of myocardial infarction - STEMI results in transmural (all the way through the cardiac muscle wall) injury, which results in elevation of the ST segment on EKG. Non-STEMI (NSTEMI), which used to be called a Non-Q-wave MI, is usually a subendocardial injury, which results in cardiac injury, but not as severe as STEMI. NSTEMIs do not have any elevation of the ST segment on EKG. These only have elevation of cardiac biomarkers on blood work.
AMI means Acute Myocardial Infarction
Acute Myocardial Infarction (AMI).
