In fact, some patients may have small myocardial infarction (non transmural) or scattered subendocardial myocardial infarction, but it can not be reflected in ECG. Sudden death can also occur. However, some patients with stable angina pectoris for many years can show progressive increase of angina pectoris in a stage, and then gradually return to stability.
