Cardiologist Soon Chao Yang said coronary atherosclerosis is a disease that leads to blockage of blood vessels of the heart.
"It is not uncommon as everybody eventually will develop it with ageing. Some will get it faster than others," said Dr Soon of Nobel Heart Centre, based at Mount Alvernia Hospital.
He added that there are generally no symptoms until the disease becomes severe.
"Unfortunately, the more severe cases sometimes end up in sudden attacks, such as in this case here," said Dr Soon.
He said factors that lead to this condition include elevated cholesterol, high blood pressure, obesity, smoking and diabetes.
"To keep all these factors in check, we have to lead a healthy lifestyle and screen for them regularly," he said.
But there are also factors beyond our control, such as gender, ethnicity and family history.
"It is more common in guys, and woman have lower risks until after menopause," he said.
Several social footballers in Singapore have died from heart attacks, but even professionals have not been spared.
