A heart attack is a serious medical emergency whereby the supply of blood to the heart is suddenly blocked, usually by fatty substances in the coronary arteries. Coronary heart disease is the term that describes this destructive process. There are many mechanisms that cause the supply of blood to the heart to be blocked.

How did Dr Gill and her team gather their findings?

The scientists analysed the genes of more than 400,000 British people and calculated that every ten-unit increase in blood pressure levels before the age of 55 raised the risk of a heart attack in later life by 43 percent.

The damage, they found, was permanent. For example, if somebody had the issue in their 40s, but it was controlled in their 60s, the harm would already be done.

Study leader Dr Dipender Gill, from Imperial College London, said: “Everybody knows that high blood pressure is bad for your heart. But nobody worries about it when they are young.

“They think, “I will think about this when I’m 60, when I’m 70”. But this evidence shows that the damage is cumulative, it is lifelong. So it is something that we should be thinking about when we are in our 30s, 40s and 50s – not putting off.”

Dr Gill added: “We found even a small change in blood pressure has a cumulative effect on heart disease risk.”

Maureen Talbot, head of clinical support at the British Heart Foundation, which funded the research, said: “Controlling blood pressure is extremely important, as it will lower your risk of serious illnesses such as coronary heart disease, heart attack and stroke.

“If you have high blood pressure when you’re middle-aged, taking proactive steps to reduce it could save your life.”

How to lower your blood pressure

One immediate step you can take is to reduce your salt intake because salt raises your blood pressure.

The NHS says to eat less than six grams (0.2oz) of salt a day, which is about a teaspoonful.

“Eating a low-fat diet that includes lots of fibre, such as wholegrain rice, bread and pasta, and plenty of fruit and vegetables also helps lower blood pressure,” adds the health body.

Heart attack symptoms – what to look for

Symptoms of a heart attack can include:

  • Chest pain – a sensation of pressure, tightness or squeezing in the centre of your chest
  • Pain in other parts of the body – it can feel as if the pain is travelling from your chest to your arms (usually the left arm is affected, but it can affect both arms), jaw, neck, back and tummy (abdomen)
  • Feeling lightheaded or dizzy
  • Sweating
  • Shortness of breath
  • Feeling sick (nausea) or being sick (vomiting)
  • An overwhelming sense of anxiety (similar to having a panic attack)
  • coughing or wheezing.

“Although the chest pain is often severe, some people may only experience minor pain, similar to indigestion,” adds the NHS.
