Common warning sign can appear 24 hours before a heart attack

The research, published in Lancet Global Health, analysed 1,672 individuals who had experienced sudden cardiac arrest.

Patients had similar symptoms the day before the attack that could have acted as warnings.

The results showed men were more likely to experience strong chest pain in the day before a heart attack.

They were also likely to sweat more and have shortness of breath, although this was less common than chest pain.

Women only experienced shortness of breath, known as dyspnoea.

Knowing the warning signs of this could help with the prevention of cardiac arrest.

Other studies into warning signs have produced similar results.

The recent research referenced a study that was carried out in Japan.

It found the three most common symptoms of a sudden cardiac arrest were caused by shortness of breath, chest pain and syncope, or fainting.

The results were based on the study of more than 1,000 people.

​One more study also found chest pain and shortness of breath to be the most common warning symptoms.

Many of the studies showed the same symptoms could present themselves before a heart attack.

While these symptoms could be an indicator of cardiac arrest, many people may notice them often.

Shortness of breath or chest pain could occur for a number of reasons.
