Heart attacks are caused by a lack of blood reaching the heart.
Without enough blood, the heart could become seriously damaged – and it may even be life-threatening.
A heart attack could also be a symptom of coronary heart disease, which is where fatty deposits build up in the arteries, which limits the amount of blood reaching the heart.
One of the key warning signs of a heart attack is developing unexplained indigestion, it’s been revealed.

“Heart attacks can mimic simple health conditions such as indigestion, panic attack, respiratory infection or sports injury,” said the Doctors Hospital of Laredo, Texas.
“Chronic or severe indigestion without burping, belching, heartburn, nausea or sour taste in the mouth [may be a sign].
“Not all of these warning signs occur in every attack.
“It’s important to know that any of these symptoms also can be present with a heart attack. Do not assume that you are just having indigestion or a panic attack. Get medical help right away.”
Most people have indigestion at some point in their lifetime, added the NHS.
You may have the condition if you develop heartburn after eating, or if you’re bringing up food in your mouth.
You don’t usually need to see a doctor if you have indigestion, and making a few diet swaps could stop the condition from coming back.
But, if you have persistent indigestion, or if you’re in severe pain, then you should speak to your GP.
Meanwhile, the most common heart attack signs include severe chest pain, having a radiating pain in your arm, and suddenly feeling very dizzy.
But you can lower your risk of a heart attack by making some small diet or lifestyle changes.
Eating a healthy, balanced diet will lower your chances of fatty deposits in your arteries.
If you think you, or someone you know, may be having a heart attack, it’s crucial that you dial 999 straight away.
