Please explain the high glucose level and high fbs in patients with myocardial infarction?

Stress: Hi. High glucose and high FBS may, repeat MAY, be seen with acute MI, but is not an absolute finding by any means. Many people have had diabetes (which actually contributes to them having an MI) but it doesn't get diagnosed until they're in the hospital for the MI. MI is a serious stress to the body, and two principle stress hormones, epinephrine and cortisol, raise blood sugar. Control diabetes!
