In the left ventricle, the blood flow decreases during systole, and most of the perfusion occurs during diastole. In the right ventricle, the flow is relatively smooth. Also during systole, the endocardium is compressed more than epicardium. This tends to decrease blood flow over there, but more blood vessels and more fall in resistance during diastole compensate for this negative impact. So overall blood flow in the inner half of the wall is almost equal to that in the outer half. Lack of oxygen or its increased demand increases the formation of adenosine, which in turn increases the blood flow. Nervous control mechanisms are there, but they are not so important, because local factors mostly predominate over them. So this was all about the coronary circulation.
