A patient with active chest pain and/or signs and symptoms of acute injury on a 12-lead ECG will be taken to the cardiac cath lab as possible for possible intervention. If the patient has ST depression or dynamic T-wave inversion, suspect ischemia of the heart muscle. The treatment per ACLS guidelines is to monitor for arrhythmias and heart failure; treat chest pain; and give adjunctive treatments such as nitroglycerine, heparin, and beta blockers. If the patient shows ST segment elevation, suggesting current injury to heart muscle, the goal is reperfusion therapy within 90 minutes via cardiac catheterization (Nuemar et al., 2010).
