NURS 3664 Lecture Notes - Lecture 6: Thrombus, Angina Pectoris, Etiology
Document Summary
When there is any kind of blockage, the heart muscle is becoming hypoxic and happens within seconds. Stemi = full blown mi, sudden 100% blockage thrombus has cut off blood supply to the heart. Acute coronary syndrome - etiology and pathophysiology. Enzymes are cut off and more severe. Acs is caused by the decline of a once stable atherosclerotic plaque. The previously totally occluded by a thrombus (manifesting as stemi). systemic inflammation (described earlier) is thought to play a role. stable plaque ruptures, releasing substances into the vessel. This area may be partially occluded by a thrombus (manifesting as ua or nstemi) or. What causes a coronary plaque to suddenly become unstable is not well understood, but. Patients with suspected acs require immediate hospitalization. Partial occlusion of coronary artery: ua or nstemi. Non occulusive thrombus, non specific ecg, normal cardiac enzymes. Increase in frequency, duration, or with less effort.
