“It may feel like pressure, squeezing or heaviness in your chest,” notes the health site.
The pain may also spread to your left or right arm or may spread to your neck, jaw, back or stomach, it adds.
It’s important to know that not everyone experiences severe chest pain.
This is particularly the case with many women, notes the NHS.
“The pain can often be mild and mistaken for indigestion,” explains the health site.
In fact, it’s the combination of symptoms that’s important in determining whether a person is having a heart attack and not the severity of chest pain, it adds.
How to prevent a heart attack
Making healthy lifestyle decisions, such as eating a healthy, balanced diet and exercising regularly is a surefire way to reduce your risk of a heart attack.
There are also lesser-known risk factors to be aware of.
Research shows that getting too much or too little sleep can raise your risk.
A study in the Journal of the American College of Cardiology found that among people ages 40 to 69, those who slept fewer than six hours per night had a 20 percent higher risk of having a first heart attack compared with those who slept six to nine hours.
However, those who slept more than nine hours had a 34 percent higher risk.
It is also important to lower your stress levels.
Harvard Health explains: “Chronic stress can increase inflammation in your body, which in turn can raise high blood pressure and lower “good” HDL cholesterol.”
HDL cholesterol lowers your risk of heart disease.
