Difference Between Cardiac Arrest And Heart Attack in Hindi
May 11, 2022
The heart is a muscle, and all muscles require oxygen-rich blood to function properly. A heart attack occurs when there is a blockage of the coronary arteries. It is not the same as a cardiac arrest. A cardiac arrest occurs when the heart stops beating, whereas a heart attack occurs when the heart continues to beat despite disruption in the blood flow to the heart.
Sudden cardiac arrest is much worse than a heart attack. It is a condition in which the victim's heartbeat stops abruptly and unexpectedly due to an abnormal heart rate or arrhythmia. A sudden cardiac arrest victim will have little or no fore-warning, will lose consciousness and collapse.
Heart Attack and Sudden Cardiac Arrest Differences
People often use these terms interchangeably, but they are not synonyms. A heart attack is when blood flow to the heart is blocked, and sudden cardiac arrest is when the heart malfunctions and suddenly stops beating unexpectedly. A heart attack is a “circulation” problem and sudden cardiac arrest is an “electrical” problem.
What is a heart attack?
A heart attack occurs when a blocked artery prevents oxygen-rich blood from reaching a section of the heart. If the blocked artery is not reopened quickly, the part of the heart normally nourished by that artery begins to die. The longer a person goes without treatment, the greater the damage.
Symptoms of a heart attack may be immediate and intense. More often, though, symptoms start slowly and persist for hours, days or weeks before a heart attack. Unlike with sudden cardiac arrest, the heart usually does not stop beating during a heart attack. The heart attack symptoms in women can be different than men.
What is a cardiac arrest?
Sudden cardiac arrest occurs suddenly and often without warning. It is triggered by an electrical malfunction in the heart that causes an irregular heartbeat (arrhythmia). With its pumping action disrupted, the heart cannot pump blood to the brain, lungs and other organs. Seconds later, a person loses consciousness and has no pulse. Death occurs within minutes if the victim does not receive treatment.
What is the link in Heart attack & Cardiac arrest?
These two distinct heart conditions are linked. Sudden cardiac arrest can occur after a heart attack, or during recovery. Heart attacks increase the risk for sudden cardiac arrest. Most heart attacks do not lead to sudden cardiac arrest. But when sudden cardiac arrest occurs, heart attack is a common cause. Other heart conditions may also disrupt the heart’s rhythm and lead to sudden cardiac arrest. These include a thickened heart muscle (cardiomyopathy), heart failure, arrhythmias, particularly ventricular fibrillation, and long Q-T syndrome.

What to do: Heart Attack
Even if you're not sure it's a heart attack, call your emergency response number. Every minute matters! It’s best to call EMS (Emergency medical services) to get to the emergency room right away. Emergency medical services staff can begin treatment when they arrive — up to an hour sooner than if someone gets to the hospital by car. EMS staff are also trained to revive someone whose heart has stopped. Patients with chest pain who arrive by ambulance usually receive faster treatment at the hospital, too.
What to do: Sudden Cardiac Arrest
Cardiac arrest is reversible in most victims if it's treated within a few minutes. First, call for emergency medical services. Then get an automated external defibrillator if one is available and use it as soon as it arrives. Begin CPR immediately and continue until professional emergency medical services arrive. If two people are available to help, one should begin CPR immediately while the other calls emergency and finds an AED. By performing Hands-Only CPR to the beat of the classic disco song “Stayin’ Alive,” you can double or even triple a victim’s chance of survival.
Sudden cardiac arrest is a leading cause of death – over 320,000 out-of-hospital cardiac arrests occur annually in the United States. By performing Hands-Only CPR to the beat of the classic disco song “Stayin’ Alive,” you can double or even triple a victim’s chance of survival.To summarize
5 differences between a heart attack and a cardiac arrest
- A heart attack is not the same as a cardiac arrest.
- A heart attack is when one of the coronary arteries becomes blocked. The heart muscle is robbed of its vital blood supply and, if left untreated, will begin to die because it is not getting enough oxygen.
- A cardiac arrest is when a person’s heart stops pumping blood around their body and they stop breathing normally.
- Many cardiac arrests in adults happen because of a heart attack. This is because a person who is having a heart attack may develop a dangerous heart rhythm, which can cause a cardiac arrest.
- A heart attack and a cardiac arrest are both emergency situations. Call emergency straight away.
