Add to that, the nurse may inform the patient that people experiencing heart attacks may also feel shortness of breath, along with sweating, weakness, nausea, and fatigue. It is important to inform the patient about these symptoms so that he/she will be aware that these are common for people with myocardial infarction and that immediate medical attention is a must.
