Q

Stable Angina

Lab findings

A

neg troponin/CK-MB

23
Q

Stable Angina

EKG findings

A

  • EKG during pain: ST depression, T wave flat or inverted (reverses when pain is gone)
24
Q

Stable Angina

tests to evaluate perfusion

2

A
  • Stress test (w/ or w/out imaging)
  • Cardiac CTA
25
Q

Stable Angina

what to do if stress test is pos?

A

heart cath

26
Q

Stable Angina

First Line Treatments

1

A
  1. beta blocker
  2. ASA (81mg PO QD) or clopidogrel (75mg PO QD)
27
Q

Stable Angina

beta blockers are the only meds which actually do what?

A

prolong life

28
Q

Stable Angina

Which secondary meds can be used?

3

A
  • long acting nitrates
  • ranolazine
  • calcium channel blockers
29
Q

Unstable Angina

sx

A
  • new or worsening sx of myocardial ischemia (pain/squeezing/tightness)
  • unstable angina may come on during rest or with minimal exerction
  • can last > 30 min in duration
30
Q

Unstable Angina

lab findings

A

troponin neg

31
Q

Unstable Angina

EKG findings

A

usually ST depression

32
Q

NSTEMI

sx

A

new or worsening sx of myocardial ischemia

33
Q

NSTEMI

lab findings?

A

troponin pos

34
Q

NSTEMI

EKG findings

A

no ST elevation

35
Q

Unstable Angina/NSTEMI

Treatment in hosp

A
  • MONA-BAS
  • CCB if cocaine induced
  • Fibrinolytics have been found to be harmful
36
Q

Unstable Angina/NSTEMI

what is MONA-BAS?

A
  • M: morphine
  • O: oxygen
  • N: nitroglycerides
  • A: aspirin
  • B: beta blocker
  • A: anti-platelet
  • S: statin
37
Q

meds prescribed upon discharge?

A
  • beta blocker

  • Statin
  • cardiac rehab
38
Q

STEMI

pathophys

A

acute episode of chest discomfort that results from an occlusive coronary thrombus at the site of a pre-existing atherosclerotic plaque

39
Q

STEMI

sx

A
  • depend on severity
  • chest pain
  • can cause sudden death and arrhythmias
40
Q

STEMI

lab findings?

A

pos troponin I/T or CK-MB

41
Q

STEMI

why is it important to trend cardiac enzymes?

A

they elevate at different times. If pt comes in early after pain onset, may not be pos yet. Trending will let you repeat 3/6 hrs later and see changes

STEMI

EKG findings

STEMI

what is indicative of STEMI until proven otherwise?

NOT ST ELEVATION BUT YES THAT TOO

A

New LBBB

in which leads will you best see lateral wall MI?

A

I, aVL, V5, V6
