Here’s All What You Need To Know About The Difference Between Heart Attack And Sudden Cardiac Arrest!

Difference Between Heart Attack And Sudden Cardiac Arrest

Heart attack and sudden cardiac arrest (SCA), these two terms are often used by people as substitutes of one another, which is, of course, not true. Both Heart attack and SCA are about the state of malfunctioning of the human heart.

In the former, the flow of blood to the heart gets blocked, while the latter is about the unexpected stopping of heart beat, explains cardiac specialists at AMRI Hospitals. The hospital has a team of the best cardiologists in Kolkata. Let’s try to de-clutter this myth and understand how these two heart problems are different from each other.

Heart Attack

Heart attack is a problem in the circulatory system, in which an artery is blocked and prevents the flow of oxygen-rich blood to the heart, say experts at the best heart specialist hospital in Kolkata.

When the artery is not reopened on time, the heart begins to wither. One can observe symptoms of heart attack for a couple of days or weeks.

Cardiac Arrest

Sudden Cardiac Arrest is caused by an electrical crash in the heart of a person that causes arrhythmia. It is sudden and comes without any symptoms, giving a person no time to recover.

Since SCA disrupts the process of blood pumping, no body organ will be able to receive the red liquid. Within minutes, the person dies after losing consciousness.

In many cases, sudden cardiac arrest occurs just after a heart attack, say cardiac specialists at AMRI Hospitals. Heart attack is one of the reasons for cardiac arrest. A number of other heart health issues may also lead to cardiac arrest.

What Can One Do?

Since there is nothing much one can do in case of a sudden cardiac arrest, the best way to save oneself is to dial the emergency number (102 in India) instantly. Although, you get some time in heart attack, you should immediately call the emergency medical service number because every second matters.

Majority of deaths in the case of sudden cardiac arrest and heart attack are due to panick under the circumstances. It is advised not to put yourself under much nervousness and take help of your doctor and a heart specialist.
