What is atypical angina?
A person with atypical angina does not have chest pain typical of classical angina, but has less common symptoms, such as weakness, faintness, sweating, and nausea. Atypical angina is more common in older individuals and in those with diabetes. Atypical angina has the same underlying cause as classical angina: narrowed coronary arteries, which reduce the supply of oxygen to the heart.
