From a lack of blood flow which is usually caused by some kind of blockage. If the muscle cells can't get blood, they can't get oxygen and they start to die. This is call necrosis. If the lack of blood last long enough a heart attack will occur.

How long can cardiac muscle be deprived of oxygen before the cardiac muscle cells start to die?
5 minutes
What cells make up the myocardium?
Most of the myocardium is composed of cardiac myocytes.
What are the properties of cardiac cells?
Cardiac muscle is a striated, involuntary muscle. Cardiac muscle cells usually contain 1 or 2 nuclei.
Which muscle cells commonly branch?
The muscle cells which commonly branch are the cardiac muscle cells. The other muscles do not have any branched cells.
Do smooth muscles have branched cells?
No, cardiac muscle cells are branched but skeletal muscle cells are linear and do not branch
Muscle tissue that has intercalated disks?
cardiac muscle cells are joined by intercalated disks.
Can New cardiac muscle cells replace cardiac muscle cells?
Cardiac myocytes (heart muscle cells) do not regenerate. They can get bigger (hypertrophy), but new cells are not made under normal circumstances. This means that when you have a heart attack or another injury to the heart and cardiac cells die, they are replaced by fibrous scar tissue which does not contract like normal heart tissue does.
What organ in the body has specialized cells that work together to form cardiac muscle tissue?
Answer for anyone looking is the fact that the cardiac muscle never stops, it cannot, otherwise you would die.
Which muscle cells can not regenerate?
Cardiac muscle cells do not have the ability to regenerate.
How do you describe the cardiac muscle?
Cardiac muscle is involuntary striated muscle. The cells of cardiac muscle have only one nucleus. The layer of the heart that contains cardiac muscle is called the myocardium.
What muscle is striated uninucleated cells?
cardiac muscle
Why is it important for cardiac muscle cells to be branched and interconnected with other cardiac muscle cells?
so electrical impulses can be carried freely between cells
