Heart attacks are a medical emergency that require immediate treatment, according to the NHS.
The condition, which is also known as a myocardial infarction, is a symptom of coronary heart disease - one of the biggest killers in the UK and around the world.
Diet changes could help to lower the risk of developing both heart disease and heart attacks.
Garlic has been recognised as a preventative to a number of cardiovascular diseases, including heart disease, a nutritionist has revealed.
The vegetable works by helping to get rid of plaque in arteries.
Plaque build-up could lead to a blockage in the blood supply to the heart, which can cause a heart attack.
“Eating garlic regularly is not only good for us; it has been linked to reducing or even helping to prevent four of the major causes of death worldwide, including heart disease, stroke, cancer and infections,” said Dr Josh Axe.
“Probably the most amazing characteristic of garlic is that it’s been shown to help reverse early heart disease by removing plaque buildup in arteries.”
A 2016 US study revealed the aged garlic extract could help to reduce the amount of plaque in arteries.
One of the lead researchers, Dr Matthew Budoff, said: “This study is another demonstration of the benefits of this supplement in reducing the accumulation of soft plaque and preventing the formation of new plaque in the arteries, which can cause heart disease.
“We have completed four randomised studies, and they have led us to conclude that aged garlic extract can help slow the progression of atherosclerosis and reverse the early stages of heart disease.”
Eating more berries could also help to prevent a heart attack, according to Harvard University scientists.
Berries are a great source of vitamin C that protects cells from oxidative stress.
“Berries are excellent sources of plant chemicals known as anthocyanins, which seem to lower blood pressure and make blood vessels more flexible,” they said.
An unhealthy diet, that’s high in fat, could cause atherosclerosis - a hardening of the arteries.
It’s also important to maintain a normal blood pressure. High blood pressure puts extra stress of blood vessels and vital organs.
Lower blood pressure by exercising regularly, and by cutting back on alcohol.
In the UK, there are almost 200,000 hospital visits for heart attacks every year.
About 915,000 people in the UK are alive today that have survived a heart attack.
