1

In pt with suspected Stemi, what is initial treatment

Cath lab, percutaneous intervention...angioplasty vs stent

2

Mitral stenosis physiologic needs

Slow heart rate. Preload.

3

Is the PAP in mitral stenosis falsely estimating the left ventricle end diastolic pressure to high or too low

Falsely estimates it too hi. Real value is lower

4

Mitral stenosis vasopressor.

Phenylephrine

5

how long does ck and ckmb last in a MI patient

2 days

6

how long does troponin last in a MI patient

10 days

7

what is pulsus paradoxus

an exaggerated decrease in sbp on inspiration

8

what cardiac conditions cause pulsus paradox

tamponade, constrictive pericarditis, heart failure

9

what lung problems can cause pulsus paradox

emphysema, asthma, pneumothorax

10

what misc caues for pulsus paradox

obesity, PE

11

does pna cause pulsus

no

12

what is associated with arterial line occlusion

prolong line, non teflon, size of radial arter, ratio of cath to radial artery, increased attempts, hematoma formation

13

when is an radial artery considered a thromboocclusion

it is considered time after the cath has been removed and a thrombus forms

14

what is the time frame for thromboocclusion of radial artery s/p cath

occurs within 48 hours after decannulation

15

does transfixtion aka through and through methoid increase arterial aa occlusion

no

16

when has heparinization of cathethers been proven useful to prevent thromboocclusion of radial aa

it is beneficial in arterial lines kept in longer than 24 hours

17

following cardiothoracic surgery, how many patients develop afib

30 to 60%

18

what are electrolyte causes for afib in ct surg patients

hypokalemia and hypomag

19

besided elelctrolyte abnorm, what other risk factors for afib s/p ct surg

male, age above 60, preop tachycardia, reduced post op card output, post op increase in b naturetic peptide

20

What is the ACC and AHA recommened about pt who just got drug-eluting stents

wait for 1 year after placement for elective surgeries

21

how much risk reduction do we see with delaying elective surgerys s/p placement of drug eluting stents

50% reduction…from 6.4 to 3.3% of cardiac injury

22

what is the risk of having surgery after having a stent placed

the antithrombotic will be stopped and pt is at increased risk of thrombosing the stent

23

what is the moa of rethrombosing the stent

lack of time for re-endothilization, procoagulant state induced by stress of surgery, rebound of procoagulant state after stopping dual antithrombotic drugs

24

what drugs are used in dual antiplatelet therapy for stented patients

aspirin and clopidogrel

25

how long should dual antiplatelet therapy be used for metal stents

1 month

26

how long should dual antiplatelet therapy be used for drug-eluting stents

12 months

27

what if the surgery is an emergency and pt has a stent…what should be done to the antiplatlete drugs

continuation of asa and stop the clopidogrel

28

what if the surgery is urgent…how should the antiplatelet drugs be dealt with

continue of asa and stop the clopidogrel 5 days prior to surgery

29

in mitral prolapse, what can help you see if a normal ef is really normal

a decrease in cardiac output can tell you how severe the regurge is

30

is tachy or brady bad for mitral regurge

brady is bad because the heart spends more time in systole
