#1 What is a Silent Heart Attack?
First, it is necessary to note that a silent heart attack is a type of heart attack only, presenting itself differently.
So, what is a heart attack? A heart attack, also known as a myocardial infarction, occurs when your heart does not receive enough oxygen, harmful to your heart. A blood clot usually causes a heart attack by obstructing blood flow through one of your coronary arteries. A coronary artery spasm can also lead to reduced blood flow.
Now let us come back to the question of what is a silent heart attack?
Also known as silent myocardial infarction, a silent heart attack is one that has few if any, symptoms or symptoms that you do not recognize as symptoms of a heart attack. But it still causes heart damage, just like a recognized heart attack, making it a cause of concern.
According to the American Heart Association, 170,000 of the estimated 805,000 heart attacks in the United States each year are silent heart attacks. Silent heart attacks are also more common in women than men.
#2 What is a Silent Heart Attack?: Symptoms
A question that arises with the mention of any medical emergency is what are the symptoms? Here is the answer to that.
When suffering from a silent heart attack, people have symptoms that one would usually not associate with a heart attack or simply atypical symptoms. They might also have mild symptoms or no symptoms at all, making them oblivious to the fact that they have had a heart attack.
To understand what is a silent heart attack and its symptoms better, let us first take a look at the symptoms of a classic heart attack. The typical symptoms of a traditional heart attack include-
- Pain in the chest that lasts longer than a few minutes
- Shortness of breath
- Sweating cold sweats

- Experiencing discomfort in your upper body
- Tiredness that can last for several days with no apparent cause.
As discussed above, these symptoms might not appear when a silent heart attack occurs.
So, when you do have a silent heart attack, you may experience other subtle symptoms such as:
- Suffering from the flu
- Excessive fatigue or exhaustion
- Experiencing a tense muscle in your upper back or chest
- Feeling pain in your arms, jaw, or upper back
- Suffering from indigestion.
#3 Causes or Risk Factors for Silent Heart Attacks
Now that we have gotten the answers to what is a silent heart attack and what its symptoms are, it is time to move on to the next question.
What causes a silent heart attack?
What causes a silent heart attack is plaque containing cholesterol accumulates in your coronary arteries. When a blood clot forms on the plaque, it prevents oxygen-rich blood from reaching the heart muscle, thus leading to a heart attack.
However, there are also certain other health problems you might be suffering from, increasing your chances of a heart attack. These health problems include:

According to the Cleveland Clinic, aside from the health problems mentioned above, there are some other risk factors for a silent heart attack. However, these things are beyond your control, and there is nothing much you can do about them. These risk factors include-

#4 How to Diagnose a Silent Heart Attack?
While it is quite clear that you would not be able to determine whether or not you have suffered from a heart attack, your healthcare provider might be able to figure it out.
Your doctor may look for the following signs of a silent heart attack-

#5 Is it a Heart Attack or Just Chest Pain?
Because chest pain is one of the most common symptoms of all heart attack symptoms, you may believe you have one whenever you experience it. However, this is not always the case because various factors can cause chest pain.
Indigestion, shingles, reflux, strained chest muscle, and inflammation in the rib joints are all possible causes of chest pain. Such causes usually do not require you to go to the hospital, but if you are unsure of the cause, it is best to bring it to the notice of a medical professional as it might as well be a heart attack or angina.
Angina, also known as Ischemic Chest Pain, is a type of chest pain for those suffering from Ischemic Heart Disease. When people with this disease move around, they tend to experience chest pain, but the pain subsides after rest. However, if the pain does not go away, you may have a heart attack.
#6 What are the Effects of a Silent Heart Attack?

However, a silent heart attack increases your chances of having another heart attack, which could be fatal. A second heart attack also increases your chances of complications, such as heart failure.
Even during the first unrecognized heart attack, some people may experience abnormal heart rhythms or suffer from heart failure.
Therefore, it is advisable not to wait too long before seeking medical attention as it could have long-term consequences and cause severe damage to your heart.

They may also perform a coronary angioplasty to open up a clogged blood vessel. In some cases, a coronary artery bypass graft may be required to allow blood to bypass the clogged area. A stent can also be inserted into the blood vessel to open it and allow proper blood flow.
Such treatment is not a one-time thing, and you would have to take proper care of your heart and health once you are discharged from the hospital.
