In other words, increased afterload results in increased end-systolic volume and less blood leaving the heart, or decreased stroke volume.

换言之，后负荷增加会导致收缩末期容积增加，离开心脏的血液减少，或每博输出量减少。

A decreased stroke volume can occur when there is an increase in the resistance in the arteries leaving the heart.

当离开心脏的动脉阻力增加时，每博输出量就会减少。
