What is the risk of having a heart attack?
The risk of suffering a heart attack is fundamentally increased with angina pectoris complaints, as both diseases are based on the same vascular changes. The best way to assess the risk is to divide the disease into stable and unstable angina pectoris. In stable angina pectoris, the disease does not progress, so the risk of suffering a heart attack is comparatively low.
Within five years, about 25% of those affected suffer a heart attack. In unstable angina pectoris, the disease becomes increasingly severe, so that a heart attack is much more likely, if not inevitable, if the symptoms and progression of the disease cannot be contained.
