Preliminary discussion that the endothelin changed before and after percufaneous coronary intervention operation of coronary heart disease

Objective Observe the relation between endothelin and coronary heart disease around percufaneous coronary intervention (PCI) operation. Methods In hospital the coronary heart disease patients collected blood from the vein in 3 days before PCI operation, the same day, postoperative half an hour or 1 days or 3 days, observe the change of endothelin in plasma. Results There are obvious differences between the endothelin which in the normal control group and 3 days before operative or the same day, having nothing difference with the half an hour postoperative group, the endothelin which in 3 days or 1 day postoperative is obviously higher than the normal control group, the endothelin of half an hour postoperative is obviously lower than foreoporation, having statistics meaning, but 1 or 3 days postoporative is no difference with foreoporative. Conclusions The endothelin is closely with coronary heart disease, but if it could be as judging the index of the PCI postoperative taking a favorable turn and prognosis also needs the further discussion.
