Final answer:
Arterial necrosis is the term that refers to the tissue death of an artery or arteries, often resulting from atherosclerosis. Conditions such as myocardial infarction (heart attack) and stroke are consequences of this arterial damage.
Step-by-step explanation:
The term that means the tissue death of an artery or arteries is 'arterial necrosis'. However, related to the specific context given here, this usually refers to the condition atherosclerosis, which is where plaque builds up in the arterial walls leading to tissue death. Conditions like myocardial infarction (also known as a heart attack) and stroke are often the results of atherosclerosis.
A myocardial infarction occurs when there is a complete blockage of the coronary arteries, which leads to the death of cardiac muscle tissue. This blockage is frequently caused by the accumulation of atherosclerotic plaque. Similarly, a stroke can occur due to the obstruction of blood flow to parts of the brain, resulting in brain cell death. Coronary artery disease, characterized by the build-up of plaque within the walls of the arteries, is the leading cause of death worldwide and can lead to these serious conditions if untreated.
