How could hypertension affect cardiac output?

Two ways: It can cause the heart muscle to get thick and stiff so that it does not relax and fill up with blood properly. It could also cause the heart muscle to become weak so that it does not squeeze or contract as forcefully. These are called diastolic dysfunction (too thick) or systolic dysfunction (weak and flabby).

Increases workload: Hypertension causes the central aortic blood pressure to increase. Going back to physics: flow (cardiac output) = pressure gradient (pressure the heart generates-blood pressure) / resistance of the vessels. So if the blood pressure is higher the pressure gradient is lower. Also the resistance may be higher.
