One last topic in this topic, of kind of cell injury and mechanisms there of is Ischemia and Reperfusion.

00:11

So, in the typical clinical setting where this occurs, a patient comes in there having crushing substernal chest pain.

00:18

They’re having a heart attack.

00:20

We know that most commonly this is due to a plaque rupture in the coronary artery with a blood clot on top of it.

00:27

So we rushed them into the angiography suite, and we inject tissue plasminogen activator, a clot buster, and we break up the clot.

00:35

Except that the heart has been ischemic for a certain period of time.

00:39

Now we’re restoring blood flow into tissues that have had partial injury.

00:45

So when that happens, we have a high concentration of extra cellular calcium that’s coming into a potentially compromise cell.

00:54

We already talked about cells.

00:56

If they see a spike of calcium, we’ll start down that calpain activation pathway, and we’ll end up with some cell death.

01:03

So that’s one part of ischemia reperfusion.

01:07

When we reperfuse ischemic tissue, we also get increased recruitment of inflammatory cells.

01:13

And recall the inflammatory cells have a rich resource of for generating reactive oxygen species.

01:21

So as a result of that, we will get more damage because we recruit more inflammatory cells into this area of reperfusion.

01:30

The damage mitochondria in that tissue.
