Chest pain Flashcards
When charting to rule out an MI, what is important to include in the chart
Pertinent negatives
What is acute coronary syndrome
umbrella for conditions from stable angina to AMI
What does it mean if nitroglycerin no longer has an effect on a person
- they have unstable angina
2. their nitroglycerin has lost efficacy from exposure to light and/or air
What are the main types of angina
Stable
Unstable
Prinzmetal/atypical
What is stable angina
anginal symptomatology that occurs with the same degree of exertion and resolves with the same degree of rest and/ or same dosage strength and frequency of NTG
What is unstable angina
angina that occurs with more frequent occurrence of anginal episodes, longer lived episodes or more easily provoked angina
What is Prinzmetal (atypical) angina
Angina that occurs at rest
Which characteristics are high risk for Acute Coronary Syndrome
Pressure or squeezing quality
Pain similar to prior AMI or angina
Radiation to neck, shoulders, or left arm
Associated dyspnea - esp diabetic or elderly
What do you do for a patient with unstable angina
Send them to the ER! If they are in the office, put them on oxygen, give them nitroglycerin (if BP systolic isn’t lower than 100), and aspirin (chewable).
Who is more likely to have atypical ACS symptoms
Women, drug users, diabetics, elderly
What Physical exam findings are of note in acute coronary syndrome
may see low BP, diaphoresis, skin color, bradycardia, unstable pulse ox
When is a family history of MI particularly significant
When it happened to first degree relative before the age of 60, with decreasing age making the history increasingly significant.
What is the signature of an evolving or completed MI
ST elevation (called STEMI) wide and deep by a box
What blood markers are used most commonly for AMI
creatine kinase-MB and troponin levels (most sensitive). troponin is normally run twice
What are the leads you see an anterior wall MI in
V1-6 you will see an ST elevation
