Q

5 differences between STEMI and NSTEMI

A

STEMI - full thickness damage, ST elevation, pathological Q waves, more elevated markers (troponin, CK-MB), PCI to treat, Thrombolysis.
NSTEMI - partial thickness damage, markers only mildly elevated, ST depression, no Q waves, T wave inversion, PCI/CABG, thrombolysis can be harmful
