The correct choice highlights that the greatest risk associated with the side effects of hypertension occurs when there is an elevation in both systolic and diastolic blood pressure. Hypertension, or high blood pressure, is typically defined by two measurements: systolic pressure, which measures the pressure in arteries when the heart beats, and diastolic pressure, which measures the pressure when the heart is at rest between beats.

When both systolic and diastolic pressures are elevated, there is a significantly increased workload on the heart and arteries, contributing to an elevated risk for cardiovascular diseases, such as heart failure, stroke, and kidney damage. This combination can indicate more severe hypertension, leading to greater potential complications compared to isolated elevations in either pressure.

Other scenarios, such as when blood pressure is normal, only elevated diastolic pressure, or limited to young patients, do not represent the same level of risk associated with the more dangerous condition of having both elevated systolic and diastolic pressures. Thus, recognizing that both measurements play a crucial role in assessing hypertension and its associated risks is essential for understanding its implications on health.
