How common is microvascular angina?

It's hard to determine the exact number of people affected by microvascular angina, because it's a symptom that can be indicative of many underlying heart conditions. However, it's a relatively common condition. Microvascular angina is caused by a narrowing of small blood arteries to the heart. This can be caused by fatty deposits in the arteries that stick to the sides and restrict blood flow. It's more common among older people. People with high blood pressure, high cholesterol, diabetes, or obesity are also more commonly affected by microvascular angina than those without those risk factors.
