Which of the following is a common manifestation of an increase in systemic vascular resistance (SVR)?

An increase in systemic vascular resistance (SVR) results in higher resistance against which the heart must pump, leading to an elevation in blood pressure; thus, hypertension is a common manifestation of increased SVR. The body attempts to maintain adequate blood flow and pressure, and when SVR rises, the pressure within the arteries increases to overcome this resistance.

Understanding the relationship between SVR and blood pressure is crucial in cardiovascular physiology. Increased SVR can occur in various conditions, such as vasoconstriction or increased blood viscosity, elements that elevate the workload on the heart and lead ultimately to hypertension.

In contrast, hypotension would reflect a decrease in blood pressure, which is not aligned with increased SVR. Decreased heart rate, typically dependent on the body's feedback to maintain adequate perfusion, would not directly correlate with an increase in SVR. Increased cardiac output generally occurs when there is a need to elevate blood flow, often in situations of low SVR, rather than when SVR is high. Thus, hypertension emerges as the primary outcome of increased systemic vascular resistance.
