What distinguishes a heart attack from heart failure.

a. a heart attack results from poor blood flow, while heart failure involves a total interruption of blood flow.

b. both heart attack and heart failure result in heart tissue death, but more tissue dies as a result of heart failure.

c. heart tissue dies during a heart attack, while heart failure results in systemic oxygen deficiency.

d. heart failure results in body tissues receiving such a high level of oxygen that it is toxic.

Both heart attack and heart failure are serious cardiovascular conditions.  A heart attack is blockage of blood flow to the heart and occurs when the blood flow that brings oxygen to the heart muscle is severely reduced or cut off completely. The heart attack is acute and sudden and causes a lot of chest pain . Heart failure on the other hand occurs when the heart cannot circulate blood through the body and is a chronic progressive process. According these explanations the following statement is true: Heart tissue dies during a heart attack, while heart failure results in systemic oxygen deficiency.  Correct C

C. Heart tissue dies during a heart attack, while heart failure results in systemic oxygen deficiency is the correct answer.

Explanation:

Heart tissue dies during a heart attack, while heart failure results in systemic oxygen deficiency distinguishes a heart attack from heart failure.

Heart failure and heart attack are kinds of heart disorders.

heat attack occurs suddenly when the blood flow to heart tissue get blocked and blood clot due to this heart muscle do not get oxygen to function properly because of lack of oxygen heart muscle starts to die.

heart failure occurs when the heart muscle gets weaker and the heart muscle is not able to pump the sufficient amount of blood is not properly pump to sustain the cell in the human body.
