Which of the following is a consequence of ischemia?

Ischemia refers to a condition where there is insufficient blood supply to a tissue, leading to a lack of oxygen and nutrients necessary for cellular metabolism. This reduction in blood supply is a direct consequence of ischemia and can lead to tissue damage and impaired function.

When blood flow is compromised, tissues do not receive adequate oxygen, resulting in a shift to anaerobic metabolism, accumulation of metabolic waste, and ultimately cell injury or death if the ischemic state persists. This is why decreased blood supply is the most direct and accurate consequence of ischemia.

In contrast, increased tissue oxygenation, improved cardiac output, and stabilized heart rate do not occur in the context of ischemia; rather, they might be seen as parameters that could be affected negatively due to the inadequate blood supply.
