Final answer:
True, You should call 911 immediately if someone is having a heart attack. A heart attack is when blood flow to the heart is blocked, and it differs from cardiac arrest, where the heart stops effective pumping.
Step-by-step explanation:
True, you should call 911 immediately if a patient is having a heart attack. A heart attack occurs when blood flow to the heart muscle is blocked, leading to the death of cardiac muscle fibers if not treated promptly.
Two cardiovascular diseases that can be caused by atherosclerosis are coronary artery disease and cerebrovascular disease. Atherosclerosis contributes to these diseases by causing the arteries to narrow due to the buildup of plaque, which can lead to blockages that cause heart attacks or strokes.
It is false to say that a heart attack is the same as cardiac arrest. While a heart attack refers to the blockage of blood flow to heart muscle tissues, cardiac arrest occurs when the heart stops pumping blood effectively. In cases of cardiac arrest, an automated external defibrillator (AED) can be vital to saving the person's life by correcting an abnormal heart rhythm.
