Cards Flashcards
GI disorders assc with chest pain
- duodenitis
- cholelithiasis
- ulcers
- gastritis
Worst risk factor for CAD? Most common?
Worst- DM
MC- HTN
Age assc with CAD in men vs women?
45 men 55 women
this is why lipids at 35 and 45
Most dangerous portion of lipid profile
high LDL (more impactful than obesity itself)
When is fam hx CAD relevant?
FIRST DEGREE, EARLY MI (65 woman, 55 male)
“Tako Tsubo”/ Broken heart syndrome pathogenesis and key findings
catechol surg; ballooning of LV
Which lifestyle change has the most immediate effect on CAD risk
smoking cessation
What pains are abnormal for ACS?
sharp/stabbing/ knifelike
Chest pain worst when lying flat is ___? How to dx?
Pericarditis
EKG (Diffuse STE, PRD)
Epigastric pain worst BETTER WITH FOOD
duodenal ulcer
Chest pain with fever =
PE or PNA
Max heart rate
220- age patient
Appearance of CAD on nuclear scan?
decreased thallium uptake
Reversible ischemia present on stress NBS
angiography –> plasty/ surgery
*NOTE YOU CAN DO NOTHING ABOUT FIXED LESIONS!
Options for stress tests
1) Exercise + EKG
2) Exercise + Thallium or Echo (for abnl EKG)
3) Diypridamole + Thallium or Dobutamine + echo (for intability to exercise)
To correct stenosis must be at least ____%
70%
Medications for stable CAD?
BBer * ASA* ACEi Statin NG PRN
*lower mortality
ASA should be used in all stable CAD/angina…
When should second antiplatelet agent (ie clopidogrel) be added?
- Acute ACS
- Recent Stenting
- In place of ASA if intolerant
When should ACEi be used?
- Low EF/Systolic Dysfunction
- Valvular Regurg
When to use statins?
All CAD patients on statins, get LDL at least below 100
Also use for CAD equivalents (Stroke, carotid disease, PAD, DM, aortic disease)
Also use for hyperlidipemia
ADRs of statins + which is MC?
- # 1: transamintitis
- myositis
- CPK ^
- rhabdo
Why is statin therapy superior to others?
largest mortality decrease, antioxidant effect on endothelial lining of arteries
Niacin ADRs
flushing, glucose/uric acid ^^
Fibrate ADRs
increased risk myositis when added to statins
Colestyramine ADRs
- flatulence/bloating
- can decrease absorption of other meds
Ezetimibe ADRs
actually well tolerated but doesn’t work worth a shit
Effect of CCBs on mortality in CAD?
actually increases due to reflex tachycardia so do not routinely use
ADRs of CCBs
edema
constipation
heart block
Indications for CABG
- 3 vessel disease
- 2 vessel disease +DM
- Left Main occlusion
- Persistent symptoms despite max therapy
Which veins are used for bypass? how long do they last?
IMA- 10 years
Saphenous- 5 years
Why is S4 heard in ACS?
Ischemia –> noncompliant left ventricle
MI location with highest mortality rate?
anterior wall (V2-4)
Increased JVD on inhalation is _____ sign?
When is it seen?
Kussmal
Constrictive pericarditis
Triphasic scratchy sound is _____ assc with ____
friction rub, pericarditis
A decrease in BP more than 10mg on inspiration is _____ assc with _____.
pulsus paradoxus; tamponade
Drug that is most important to give immediately in ACS to lower mortality (while activating cath lab)
ASA
Which management should always be “NBS” in ACS?
whatever lowers mortality
How long from MI does it take for troponin to rise?
4- 6 hours
Appropriate door to balloon time? Door to needle? (thrombolytics)
90 mins; 30 mins
What best prevents restenosis following angioplasty?
drug eluting stent
Contraindications to thrombolytics?
What to do if pt has these?
CNS/GI bleed, surg last two weeks, stroke last 6months, BP 180/110
*Transfer for angioplasty even if will be more than 90 mins
When are GPIIB/IIIA inhibitors used?
abciximab, tirofiban, eptifibatide
stenting; NSTEMI not STEMI
When is heparin used in ACS?
NSTEMI
Drugs given in case of NSTEMI
1-2) ASA, antiplatelet
3) BBer
4) Nitrate, morphine, O2
5-6) Heparin, GPIIBIIIAI
Drugs given in case of STEMI
1) ASA, Statin
2) BBer
3) Thrombolytics –> heparin or stenting
4) statin
5) morphine, nitrates, o2
Clue to right ventricular infarct?
Inferior MI’s (leads II,III,avf)
Clear lungs
STE in RV4
Special treatment for RVI
no nitro
extra fluids
How does 3AV block assc with MI present?
cannon A waves
symptomatic bradycardia
Presentation of tamponade/wall rupture post MI
sudden loss of pulse, JVD
several days after the original MI
Presentation of valve or septal rupture post MI?
How to dx?
new onset murmur
pulm congestion
need echo
Purpose of intraaortic balloon pump
bridges to surg in anatomic lesion… 24-48 hours
Management of post MI mural thrombus
heparin –> warfarin
