Prodromal fatigue
The prodromal stage of a disease is an early stage with unspecific signs and symptoms as the disease slowly develops. Myocardial infarction does not usually develop slowly. It is rather abrupt and without notice. However, some patients may have a prodromal stage characterized by fatigue and general malaise for a few days. They may also feel some chest discomfort, especially if they suffer from angina pectoris.
