Final answer:
The term 'heart stoppage' is another term for cardiac arrest. Conversely, a heart attack, also known as a myocardial infarction, involves the blockage of blood flow leading to the death of heart muscle cells. Heart failure and heart blockage are related conditions but not synonymous with cardiac arrest.
Step-by-step explanation:
Another term for cardiac arrest is heart stoppage. Cardiac arrest occurs when the heart stops pumping blood adequately, which can lead to the cessation of vital organ functions due to lack of oxygen. This is a serious medical emergency that requires immediate attention. In contrast, a heart attack, or myocardial infarction (MI), happens when blood flow to a part of the heart is blocked, causing death of myocardial cells. A heart attack may cause irreversible damage to the heart muscle and is a result of blockage, commonly due to atherosclerotic plaque, blood clots, or the rupture of plaque in the coronary arteries. Heart failure is a condition where the heart is unable to pump blood effectively to meet the body's needs, but it is not synonymous with cardiac arrest. Similarly, heart blockage refers to the obstruction of blood flow, which can lead to a heart attack, but is not another term for cardiac arrest.
