If you just went through a few diagnostic tests and the doctor told you that you had a heart attack and not a cardiac arrest, how would you interpret it? Should you be a bit relieved or more worried?
As you can see, medical definitions can be confusing, so you need to understand the key differences between these two cardiac emergencies.
Heart attacks often occur because of coronary heart diseases, which means that the heart is not getting enough oxygen-rich blood and it’s slowly dying. It might happen because of your age, diet, habits, or because of other medical complications.
On the other hand, cardiac arrest occurs when your heart’s electrical system breaks down or malfunctions. It generally happens because of arrhythmias that interfere with the electrical pulses of the heart, causing irregular heartbeats.
In this article, you will learn the difference between heart attack and cardiac arrest, including the difference between their symptoms, risk factors, diagnosis, and treatment methods.
Heart Attack vs. Cardiac Arrest: The Fundamental Difference
A heart attack, also known as myocardial infarction, is when the blood flow to the heart is cut off for some reason. As the heart is unable to get enough oxygen-rich blood, it causes damage to the heart itself, and the heart muscles start dying.
On the other hand, cardiac arrest is a condition where the heart suddenly stops beating. It’s an extremely serious medical issue as it can result in permanent disability or near-immediate death.
Comparing the Symptoms of Heart Attack and Cardiac Arrest
Whether it’s a heart attack or cardiac arrest, both are emergency medical conditions that can threaten your life. That’s why it would be wise to learn more about the symptoms of each of them.
Heart Attack Symptoms
Most of the time, heart attacks can start with sudden chest pain. However, the symptoms can also involve slow and mild chest pains that continuously come and go over a few hours.
The point is that heart attack symptoms can greatly vary. And if you have already suffered from a heart attack once, a different kind of symptom may show up until you suddenly suffer from another attack.
The symptoms of heart attack can be different for men and women. Still, chest pain is one of the most common indicators of heart attack that appears in both sexes.
Please remember that women often suffer from a wider variety of symptoms than men, which includes nausea, vomiting, shortness of breath, back pain, jaw pain, etc.
Symptoms of Cardiac Arrest
Before people suffer from cardiac arrest, they often don’t even know that they have a problem related to the heart. When people experience cardiac arrest, they might suddenly collapse or lose consciousness. They can even experience difficulty in breathing or stop breathing entirely.

Heart Attack vs. Cardiac Arrest: The Causes and Risk Factors
The risk factors and the reasons for heart attack and cardiac arrest are quite different from each other. In the case of a heart attack, many people already have a prior idea that they might have a problem related to the heart and that they are at risk of suffering from a sudden heart attack.
In the case of cardiac arrest, however, many people are actually clueless about the condition of their heart, making them ignore the risk factors.
Causes of Heart Attack
Coronary heart disease is often the main culprit behind heart attacks, which happen because of the lack of oxygen supply to the heart tissues. So, the people who are already being treated for such heart disease already know that they may suffer from heart attacks.
Here’s a list of risk factors that are responsible for heart attacks:
- Lack of exercise
- High cholesterol
- Unhealthy diet
- Smoking
- Being overweight
- High blood pressure
- High blood sugar level
Causes of Cardiac Arrest
Several health factors and heart conditions, including heart diseases like coronary heart disease, may become the final trigger of cardiac arrest. Here’s a list of factors that might put of at risk of this cardiac emergency:
- Congenital disease
- Enlarged heart
- Irregularly-shaped valves of the heart
- Smoking
- Previous heart attacks
- Problems related to electrical impulse
- A long-term family history of heart diseases
- Substance abuse
How Do Experts Diagnose Heart Attack and Cardiac Arrest?
Doctors and medical experts can find out the difference between heart attack and cardiac arrest after running a few specific tests.
So, if you’re suffering from some kind of heart problem or suspect that you have heart-related medical complications, you need to go through a thorough diagnosis. You should contact expert diagnostics like Agilus Diagnostics to conduct such tests.
Heart Attack Diagnosis
Experts often perform a few sets of physical exams or perform an electrocardiogram and check your heart’s activity to diagnose the signs of a heart attack.
The doctors might even put you through an electrocardiogram or cardiac catheterization to check the strength and vitality of your heart. People in diagnostics centers or hospitals might also take a few samples of your blood to check if there are any signs of heart tissue damage.
Cardiac Arrest Diagnosis
When people suffer from cardiac arrest, it means that their heart has literally stopped beating. And without immediate CPR, it’ll be a fatal situation.
Once a doctor or anyone successfully restarts your heart, you will have to go through multiple diagnostic tests to find out the reason behind the cardiac arrest. Such tests might include blood tests, electrocardiograms, and even X-rays of your chest.
Treatment Options for Heart Attack and Cardiac Arrest
The treatment option for these two heart diseases depends on several factors, such as:
- Your medical condition and the types of medicine you’re currently taking.
- The seriousness of heart diseases.
- Your overall health and vitality. Doctors need to ensure that your body is healthy enough to withstand surgery or other medical procedures.
Now, let’s see the types of medical treatments that can be used to treat heart attacks and cardiac arrests.
Treating Heart Attack
If you have already suffered from a heart attack once, medical experts may go through several procedures or medications, depending on the gravity of the situation, to prevent another heart attack. They may also perform several medical procedures to make the pain related to your previous heart attack go away.
Some of these treatments are:
- Angioplasty
- Heart valve surgery
- A stent
- Heart bypass surgery
- Pacemaker insertion
- And in extreme cases, a heart transplant surgery
Doctors can also prescribe several medicines like beta-blockers, pain relievers, and nitroglycerin to relieve pain and prevent another heart attack.

Treating Cardiac Arrest
CPR and a defibrillator are almost always the first methods used to treat a patient who has suffered from cardiac arrest. If the patient survives, the doctors will proceed with the other treatment methods, which may include,
- Surgery
- Medications
- Giving proper instructions to help the patient live an active life.
Wrapping It Up
While it’s easy to become confused between heart attacks and cardiac arrests, you must remember that both of them are some of the most serious and fatal medical conditions. If you suspect that you’re experiencing any heart-related problems or see several symptoms of heart attack and cardiac arrest, contact a doctor immediately.
The doctors and their teams can check the symptoms and run several diagnostic tests to evaluate your condition and start appropriate treatments. In most cases, the chances of your survival are directly related to how quickly you seek medical attention.
