Final answer:
Sudden Cardiac Death is known as Cardiac Arrest, which is different from a heart attack, though one can lead to the other. Heart attack (or myocardial infarction) results from blockage in coronary arteries, while cardiac arrest is when the heart’s pumping action is halted.
The correct answer is options 1.
Step-by-step explanation:
Sudden Cardiac Death is also known as Cardiac Arrest. Cardiac arrest occurs when the heart can no longer effectively pump blood, which is a dire medical emergency that requires immediate intervention. A heart attack, or myocardial infarction, is a complete blockage of the coronary arteries leading to death of cardiac muscle tissue. While heart attacks can lead to cardiac arrest, they are not the same; heart attacks are caused by blockages in the blood supply to the heart, whereas cardiac arrest is an electrical problem that stops the heart's function.
Atherosclerosis of arteries that supply the heart muscle is known as coronary heart disease and can lead to heart attacks. Symptoms of a heart attack may include chest pain and breathlessness, whereas cardiac arrest typically results in a sudden loss of consciousness and no pulse due to the heart’s inability to pump blood effectively. Coronary artery disease can lead to heart attacks, arrhythmias, heart failure, and cardiac arrest, and it remains the leading cause of death in the United States.
