In brief: About 4%
About 4% of the cardiac output goes to the heart muscle itself.
That is the same either at rest or with exercise.

In brief: Cardiac output
The major organs get about 80% of the total co.
The percent each gets varies depending on the dynamics going on. As the heart can vary its resistance markedly coronary blood flow can vary by a factor of 5 depending on heart rate and resistance so it isn't a constant percent of co.
