Myocardial Infarction Flashcards
Name 3 causes of MI
Atherosclerosis, Coronary artery spasm, coronary embolism, coronary artery dissection.
Name 4 diagnostics used to diagnose MI
12-lead ECG, Enzymes, Echo, Clinical Symptoms
ST elevation in leads two three and AVF signal what kind of MI
Inferior
ST elevation in leads V2 through V6 indicate what type of MI?
Anterior
ST elevation in leads 1 AVL, V5-6 indicate what kind of MI?
Lateral
How long should bed rest last for a patient with a stable MI?
24 hours
List the primary pharmacologic treatment for MI
Oxygen, aspirin, nitrates, morphine, fibrinolytic therapy.
Name one contraindication for the use of morphine in acute MI.
Systolic blood pressure less than 90
Name absolute contraindications for Fibrinolytic therapy
Previous intracerebral hemorrhage, structural cerebral vascular lesion, malignant intracranial neoplasm, ischemic stroke within three months, suspected aortic dissection, severe closed head injury of facial trauma within three months.
What is the relationship between an MI and carcinogenic shock?
Acute MI causes damage to heart muscle. Damaged heart muscle = impaired pumping.
What respiratory symptom is commonly associated with an Anterior MI?
Pulmonary edema related to impared LV function.
A right inferior MI is most likely to cause:
a: Bradycardia
b: Pulmonary edema
c: Hypotension
d: Tachyarhythmias
e: all of the above
f: a and c
g: b and c
f: Bradycardia and Hypotension
Name four possible contraindications for cardiac cath.
Allergy to seafood, Reaction to contrast, Current use of sildenafil or other phosphodiesterase inhibitor, or pregnancy.
Name two possible risks associated with Cardiac Cath
Hypotension, contrast reaction, Stroke (Cholesterol emboli), and Trauma r/t hematoma or coronary dissection.
Name the indications for PCI vs Fibrinolytic therapy.
Onset of ACS>3 hours, Fibrinolytic contraindicated, High risk for Heart Failure, STEMI diagnosis is not absolute.
