The term ischemia refers to abnormal heart sounds.
a. true
b. false

The answer is b. False

Explanation:

Ischemia refers to the detention or decrease in the blood flow through the arteries to a determined area. When this happens, cells located in that area are unable to receive enough oxygen and nutrients, therefore they are susceptible to suffer damage. Depending on the level and duration of the ischemia, the damage can be minor or extremely severe.

Whenever we are in presence of heart ischemia, the heart muscle cells suffer deprivation of oxygen and nutrients, and in consequence the cellular function is altered. Due to this fact, the heart beat and the heart sounds might be affected. Heart ischemia is usually caused by blockage of the coronary arteries. This event is referred as a myocardial ischemic infarction.
