What disease can lead to ischemia due to small arterial obstructions?

Infarction refers to the localized death of tissue due to a lack of blood supply, which often results from obstruction of blood vessels. When small arteries become blocked, typically through a process related to the build-up of fatty deposits, thrombosis, or embolism, the supply of oxygen and nutrients is diminished to the tissue that the artery supplies. This lack of blood flow is what causes ischemia, which can lead to cell damage or death in that area.

For instance, in cases of myocardial infarction, a blockage in the coronary arteries can lead to ischemic damage to heart tissue, emphasizing the direct relationship between obstruction of small arteries and ischemic conditions. Thus, infarction is directly connected to the concept of ischemia arising from arterial obstructions.

The other options may involve aspects of vascular disease but do not directly cause ischemia through small arterial obstructions in the same manner. For example, fibrosarcoma is a type of cancer that can cause problems in the surrounding tissue but isn't specifically linked to ischemic events through arterial blockage. Myocarditis is an inflammation of the heart muscle that can affect heart function but isn't primarily about small artery obstructions. Aneurysms involve the dilation of blood vessels but do not inherently cause ischem
