Cardiac damage: Hypertension, if not treated, leads to myocardial hypertrophy, accelerated atherosclerosis resulting in inadequate blood supply to heart muscle that leads to impaired heart function and decreased cardiac output/heart failure.

Hypertension: High blood pressure usually implies an increased peripheral vascular resistance for a time the heart can keep up with the resistance late in the course the heart begins to not be able to generate the stroke volume against the resistance and cardiac output may fall. If abnormal ventricular function is present, cardiac output may fall earlier.
