Heart attack Vs Sudden Cardiac Arrest :Understanding The Difference

Heart Attack Ranka Hospital
Understanding the difference between heart attack and sudden cardiac arrest could help save lives, One way to understand the difference between the two condition’s is this distinction : the heart attack victim is awake and the heart is beating. In contrast the sudden cardiac arrest victim is not awake and the heart is not beating. To survive sudden cardiac arrest, the victim needs immediate CPR and treatment with a defibrillator.

One person dies every 33 seconds owing to an heart attack in India, Deadly condition is making Indians its victims 10yrs head over the people in the west. Approximately 4280 out of every 1lakh people die every year from sudden cardiac arrest and about 2/3 of the time it occurs in the younger population due to electrical heart abnormalities.

Its a common misconception that heart attack and sudden cardiac arrest are the same thing. In reality, the two conditions are quite different

Heart attack or myocardial infarction ,occurs when part of the hearts blood supply is reduces or blocked,causing the heart muscle to become injured or die.victims may complain of various symptoms including:

  • Mild Intermittent chest discomfort that lasts a few minutes and comes and goes over a period of days
  • Pain or Discomfort in one or both arms that spreads to the shoulders, upper back neck or jaw Shortness of breath
  • Nausea, sweating, lightheadedness
  • A general sense of anxiety
  • A tendency to deny that anything serious is happening
  • Women sometimes experience additional symptoms including:
    1. Stomach or Abdominal pain
    2. Weakness and overwhelming fatigue
    3. Swelling of the ankles and lower legs.

When someone has heart attack, he or she is awake and the heart is beating,It’s important to act right away to maximize the odds of survival and minimize permanent damage to the heart.

While Heart attack is often described as a “plumbing problem”sudden cardiac arrest is more of an “electrical problem” that prevents the heart from functioning effectively.Heart attacks can lead to sudden cardiac arrest,but there are many other causes as well, Including Congenital and electrophysiological abnormalities,severe heart failure, electrocution,and drug overdose.

In contrast,when sudden cardiac arrest occurs , the heart stops beating altogether.As a result ,Blood is no longer pumped throughout the body,including the brain.The person suddenly passes out,loses consciousness,and appears lifeless- except for abnormal gasping,which may last several minutes.Sometimes Victims experience Seizure activity at the onset of the event.

The sudden cardiac arrest victim is not awake and the heart is not beating if no one provides immediate help,the victim will die with in minutes. When sudden cardiac arrest occurs it is critically important for bystanders to immediately call cardiac ambulance or to take the victim to the near by hospital where CPR and other interventions can be carried out this is life saving care that any one can provide.While it is best to be trained in CPR and the use of AEDs,even without formal training,Follow dispatcher instructions,Push hard and fast on the center of the victims chest ,and follow the directions of the AED while waiting for EMS to arrive.

Sometimes people hesitate to help because they are afraid they might do something wrong and hurt the victim.But since the cardiac arrest victim is clinically dead and cannot get any worse,By stander actions can only help.

RISK factors for Sudden cardiac arrest include:

  • A previous heart attack A previous episode of cardiac arrest
  • A low(<35 percent) ejection fraction (the heart’s ability to pump blood)
  • Underlying heart conditions such as coronary artery disease,congenital heart disease (e.g.,hypertrophic cardiomyopathy), electrophysiological abnormalities (e.g., long QT syndrome,Wolff-Parkinson-White disease, Brugada syndrome)
  • Severe Heart Failure
  • Marked changes in electrolytes in the blood
  • A tendency to faint
  • Hyperthyroidism
  • Electrocution
  • Drug Abuse
  • A family history of Heart disease or stroke ,Especially having relatives who died suddenly before age 50
  • If your loved ones have one or more of these risk factors,they maybe at risk for sudden cardiac arrest.if this is the case, they should see a cardiologist or heart rhythm specialist
    (electrophysiolgist) for an evaluation. The physician may recommend implantable cardioverter defibrillator therapy, Medications,or other measures to prevent sudden cardiac death.
    In Summary, heart attack victims are awake and typically experience discomfort or pain.While they do not need CPR or treatment with a defibrillator,it’s essential to call cardiac ambulance so they can be transported immediately to the hospital. In contrast sudden cardiac arrest victims are not awake and need immediate CPR ad treatment with a defibrillator.You can save a life by learning to recognize these conditions and being prepared to take appropriate action.
