People often think that a heart attack is the same thing as a cardiac arrest. However, there are differences you must know about. It is first vital to comprehend what occurs in both of these processes in order to distinguish between a heart attack and a cardiac arrest.

What is a heart attack?

One can get a heart attack when the blocked artery prevents oxygen-rich blood from reaching the various parts of the heart. If the blocked artery fails to reopen, then the part of the heart that is usually nourished by that artery tends to die. The longer a person goes without treatment, the greater the damage will be.

Symptoms of heart attack: If a person is having a heart attack, he or she will experience symptoms that are intense and immediate. You may experience chest pain, left arm pain, fatigue, dizziness, cold sweat, indigestion, nausea, discomfort, shortness of breath, or shoulder discomfort etc. Sometimes, the symptoms of heart attack start slowly and persist for hours, days, or weeks before the heart attack strikes in. You should be able to identify these symptoms and seek medical help.

What is cardiac arrest?

One can get cardiac arrest, also known as sudden cardiac arrest (SCA). It can be seen owing to the electrical malfunction in the heart as a result of irregular heartbeat (known as arrhythmia). When the heart’s pumping action gets disrupted, the heart is unable to pump enough blood to other parts of the body like the lungs and even the brain. One can even lose life due to a sudden cardiac arrest if he/she doesn’t get treatment on time. So, timely intervention is key in case of sudden cardiac arrest as the heart tends to beat faster.
