The blockage causes less blood to flow through the heart. This reduced blood flow means that the heart cells do not receive enough oxygen, which is essential for their survival.

Answer
With less oxygen available, heart cells are unable to perform respiration efficiently. This leads to less energy being produced, resulting in cell death if the oxygen supply is not restored.
