CHD generally affects more men than women, although from the age of 50 the chances of developing the condition are similar for both genders. • As well as angina (chest pain), the main symptoms of CHD are heart attacks and heart failure.

If heart pains last longer than 15 minutes, it may be the start of a heart attack. • Unlike angina, the symptoms of a heart attack aren’t usually relieved using a nitrate tablet or spray. • In some cases, a heart attack can occur without any symptoms. This is known as a silent myocardial infarction and is more common in people with diabetes
