Are there different types of angina?
Stable angina is usually caused by physical exertion, as your heart works harder to move blood through narrow arteries to meet oxygen demand. Unstable angina is less predictable and less responsive to treatment, tends to occur more often in the elderly, and can be a sign that a heart attack is about to occur. Variant angina is a rare form of angina that mainly affects young people. It occurs during rest and results from spasms of the coronary artery.
