Can myocardial infarction cause stress hyperglycemia

Acute myocardial infarction may cause stress hyperglycemia.

Stress hyperglycemia is a response to a stressful situation such as severe illness or trauma. When the body feels stressed, it releases hormones such as adrenaline and glucocorticoids, which cause blood sugar levels to rise. Myocardial infarction itself is a severe stressful situation because it involves heart surgery and physical trauma. Pain, blood loss, anesthesia, etc. during surgery can all trigger stress reactions that lead to high blood sugar. In addition, some patients may need insulin therapy or other medications after MI, which may also affect blood sugar levels.
