Document Content and Description Below

Cardiac Alterations  Acute MI o Signs and symptoms  S/S in women- extreme fatigue, diaphoresis, abdominal discomfort, arm and shoulder pain, nausea/vomiting, indigestion, SOB, bradycardia, d... izziness, hypotension  Normal s/s- midsternal chest pain, Severe, crushing, and squeezing pressure may radiate, unrelieved with nitrates, pale and diaphoretic, dyspnea and tachypneic, syncope, nausea and vomiting, dysrhythmias o Diagnostic tests: based on s/s, analysis of 12 lead ECG, and cardiac enzymes  12-lead: ST elevation followed by Q wave formation (Q-wave myocardial infarction or STEMI) – This is the more severe type of AMI, requires immediate intervention send to Cath Lab. A STEMI occurs b/c of plaque rupture leading to complete occlusion of artery. 1 st thing you do  ST depression (non–Q-wave myocardial infarction or NSTEMI). NSTEMI results from a partially occluded coronary vessel> heparin, nitro> then will go to cath lab  Elevated cardiac enzymes- serial enzymes every 6 hours  CPK & CPK-MB  Serum troponin I: (0.05) most specific for cardiac muscle, will rise w/in after injury  Myoglobin  PTT ( ), INR 2-3, CBC, electrolytes  Stress test: exercise the heart while monitoring VS and ECG  Chest x-ray: can show fluid and a mass  Echocardiography: tells you fx of left ventricle, shows structures o Transthoracic echocardiography o Transesophageal echocardiography: better pictures  Cardiac catheterization may be performed o Ask about allergies to shellfish and contrast o If they have allergies block H1 w/ Benadryl and H2 with Pepcid o If they have a reaction during test stop give medication and support respiratory system  Diagnosis is confirmed w/ ST elevation [Show More]
