Difference Between Cardiac Arrest and Heart Attack

Cardiac Arrest vs Heart Attack: Key Differences & Warning Signs

Sudden cardiac arrest and heart attack are two different conditions. A sudden cardiac arrest happens due to a sudden stop of the cardiac rhythm. Whereas, a myocardial infarction or heart attack occurs when there is a blockage in the blood flow to its ventricles (lower chambers). Both conditions are severe and require immediate medical attention.

What is the Main Difference Between a Heart Attack and Cardiac Arrest?

In this table, we will discuss some major differences between a heart attack and cardiac arrest.

What is the Link Between Sudden Cardiac Arrest and Heart Attack?

These two severe heart conditions are linked to each other. It is common for a sudden cardiac arrest to occur after a heart attack. Particularly, heart attacks increase the risk of sudden cardiac arrest. Sometimes, heart attacks do not lead to sudden cardiac arrest, but in the case of sudden cardiac arrest, a heart attack is common.  

Other congenital heart diseases can lead to sudden cardiac arrest, including:

• Heart failure
• Cardiomyopathy
• Arrhythmias
• Infections
• Ventricular Fibrillation

Lifestyle Changes after a Heart Attack and Cardiac Arrest

Surviving a sudden cardiac arrest is the beginning of your recovery journey. However, after a cardiac arrest, some survivors experience physical, mental and emotional changes, but these changes are not permanent and can be overcome with time and lifestyle adjustments.

Let’s discuss some lifestyle changes the patient needs to follow after a cardiac arrest or heart attack:

1. Be aware of medical devices: After a sudden cardiac arrest, many survivors get an implanted defibrillator (ICD). Make sure you and your family are aware of this device and better understand how it works.
2. Follow the advice of the medical team: The survivors of sudden cardiac arrest would always worry about the possibility of another cardiac arrest. Although to prevent yourself from cardiac arrest, it would be best if you follow the advice of your healthcare professional.
3. Depression or anxiety: You may struggle with depression or anxiety after a cardiac arrest, but you don’t need to worry, as it's normal and can be managed. It is advisable to talk to your family and friends to feel better and regain confidence.
4. Be physically active: Sit less and move more. Engage in cardiovascular exercise as it can strengthen your heart, lower your blood pressure and help maintain a healthy body weight. However, be sure  to talk to your doctor to better understand which level of activity is appropriate for you.
    

Quitting Smoking: If you smoke, quit it because it is one of the most essential steps to prevent the risk of a heart attack. If you need help, consult your doctor about smoking cessation programs and medicines that can help you.

What are the Warning Signs of a Sudden Cardiac Arrest and a Heart Attack?
