“Coronary heart disease is the term that describes what happens when your heart’s blood supply is blocked or interrupted by a build-up of fatty substances in the coronary arteries,” the NHS says.
“Over time, the walls of your arteries can become furred up with fatty deposits.
“This process is known as atherosclerosis and the fatty deposits are called atheroma.”
People who are most at risk of developing heart disease include heavy drinkers as well as those with high cholesterol, high blood pressure or diabetes.
