These Are the Key Differences Between Sudden Cardiac Arrest, Heart Attack And Stroke

Most often people confuse the differences between heart attack, stroke and cardiac arrest. These are different conditions but equally serious, and can affect almost anyone. You must learn about their symptoms, causes and risk factors so that early treatment or preventative action can be taken.

Heart Attack

Heart attack is caused due to the blocking of blood supply to the heart.

  • It can happen when there is blockage of blood flow to the heart and some parts of the organ no longer receive supply of oxygen.
  • Artery blockage is one of the causes in which case the inner walls of arteries get blocked due to deposition of cholesterol or plaque. The blockage could also be caused due to a blood clot that prevents blood supply to the heart.


Symptoms of Heart Attack

Some of the main symptoms of heart attack include:

  • Sensation of pressure in the chest
  • Sensation of constriction in the chest
  • Nausea
  • Uneasiness
  • Cold sweats
  • Breathlessness
  • Pain in the arms, shoulders, jaws and upper back (especially in the left side)

In some cases, women may suffer from no symptoms or very mild symptoms.

Risk Factors for Heart Attack

The main risk factors for heart attack are:

  • Stress
  • Hereditary
  • Hypertension
  • Gender
  • Age
  • Being overweight
  • Lacking activity
  • Suffering from diabetes
  • Unhealthy food habits

If anyone experiences heart attack they must be provided instant medical care. Fast treatment can help prevent serious damage to the heart. The heart continues beating during a heart attack.

Cardiac Arrest

Cardiac arrest is related to the electrical system of the heart.

  • In this case your heart stops without any warning because it is no longer capable of functioning.
  • This is caused due to the failure of the heart’s electrical system. Due to some problem the rhythm of beating gets affected, which could lead to total stopping of heart’s function – pumping blood.
  • Anyone who suffers from sudden cardiac arrest must receive instant treatment. Failing proper and timely treatment, the patient can die in minutes. During a cardiac arrest, the hearts starts beating in a way that it is trembling and doesn’t pump blood. This leads to drastic shortfall in oxygen supply to the brain and other organs. This initiates death at the cellular level.
Symptoms of Cardiac Arrest

The following are the common symptoms of someone experiencing from cardiac arrest:

  • Out of breath
  • Entire lack of breath
  • Becoming unresponsive
Risk Factors for Cardiac Arrest

Some of the main risk factors associated with cardiac arrest include:

  • Hereditary cases
  • Coronary heart disease
  • Age
  • Smoking
  • Drug abuse
  • Alcohol
  • Gender
  • Arrhythmias

Surveys show that over 360,000 Americans die due to sudden cardiac arrest before they are able to get medical attention.


Stroke is caused when there is serious decline in the supply of blood to the brain.

  • It happens when an area of the brain is not getting sufficient oxygen because of serious decline or blockage of blood supply.
  • It will normally occur because of a blood clot in a blood vessel connected to the brain.
  • It can also occur when a blood vessel bursts because of blockage. In this case, it is known as hemorrhagic stroke.
Symptoms of Stroke

The main symptoms associated with stroke include:

  • Lack of sensation on the face
  • Feeling weak on the face
  • Weakness or lack of sensation on one side of body
  • Problems with speaking
  • Lack of coordination and problem with body movement
  • Feeling confused
  • Abrupt and extreme headache

If someone is suffering from stroke, it should be treated immediately. Immediate medical attention can help save the person’s life and also prevent further damage and problems like paralysis.

Risk Factors for Stroke

The main risk factors for stroke include:

  • Hypertension
  • Hereditary
  • Gender
  • Age
  • Ethnicity
  • Being overweight
  • Earlier history of stroke
  • Earlier history of temporary ischemic attack
  • Diabetes
  • Alcohol or smoking
  • Blood problems

Stroke is considered as the main cause behind long-term paralysis or disability in Americans.
