Temperature of 38°C after a myocardial infarction is most likely caused by what?

Fever after a myocardial infarction is typically due to the inflammatory response to damaged heart tissue. When heart muscle cells die, immune cells rush in and release cytokines such as IL-1, IL-6, and TNF-alpha. These cytokines act on the hypothalamus to raise the body's temperature set point, producing a fever around 38°C. This is a sterile inflammatory process, not an infection. Dehydration or a medication reaction are less likely explanations in this context, and an actual infection would usually bring additional signs or occur with a different timeline.
