How is ESR affected by myocardial infarction?

Answer 1

The ESR (or sedimentation rate) is a marker for acute inflammation. In the case of a myocardial infarction it is typically elevated within 3 days of the infarction and may remain elevated for weeks after.

Answer 2

In an MI, heart muscle dies. When they die, they release enzymes etc. leading to an inflammatory cascade developing, white blood cells being attracted to the area etc. They also release inflammatory proteins that stick to the RBCs, causing them to stick as they fall in the ESR tube and slowing their descent, hence prolonging the ESR time.

Answer 3

ESr is an indicator of inflammation somewhere in the system. Miocardial infractions can lead to damage of the heart muscle and as a result the immune system would be activated as a result of the tissue damage so in time it would be reasonable to assume that the ESR would rise until the situation was brought back under control
