Health experts are urging people to do a simple stair test to see if they are at risk of heart disease.
It has been suggested one of the UK's deadliest killers can be detected by walking up the stairs, BirminghamLive reports.
Heart and circulatory diseases cause a quarter of all deaths in the UK, that's more than 160,000 deaths each year – or one death every three minutes, according to the British Heart Foundation.
To perform the test, try and walk up four flights of stairs.
If you are able to trek up the flights without trouble, you're not a risk, a study says.
Experts and researchers from the University Hospital A Coruna in Spain believe those who can manage the feat in less than a minute have better heart function.
Lead author Dr Jesus Peteiro, a cardiologist at University Hospital A Coruna, Spain, said: "The stairs test is an easy way to check your heart health.
"If it takes you more than one-and-a-half minutes to ascend four flights of stairs, your health is suboptimal, and it would be a good idea to consult a doctor."
The main symptoms of coronary heart disease are: chest pain, shortness of breath and pain throughout the body, as well as feeling faint and also feeling sick (nausea).
Last week, it was revealed in a study during a follow-up of almost 16 years of adults with hearts disease that continued low physical activity was linked to 19 per cent lower risk of dying from any cause.
And sustained high physical activity was linked to a 36 per cent lower risk of death compared to those who are inactive, the Nord-Trondelag Health Study found.
There are about 7.6million people living with heart and circulatory diseases in the UK, according to the British Heart Foundation.
Speak to your GP if you think you could be at risk for heart disease.
You can expect to be asked about your medical history, have your blood pressure checked and have a blood test done.
