Q

Why is there no obstruction of blood flow with Monckeberg arteriolosclerosis?

Q

Markedly unequal BP in arms is associated with which cardiac pathology?

A

Aortic dissection

19
Q

Difference between Stanford A and Stanford B type Aortic dissection?

A

Stanford A - more proximal, asc aorta –> aortic arch
Tx/surgery
Stanford B - more distal, aortic arch –> desc aorta
Tx/BB, VD

20
Q

What differentiates unstable angina vs NSTEMI?

A

No rise in cardiac biomarker elevation

21
Q

What is Coronary steal syndrome?

A

Giving vasodilators in a patient with coronary stenosis will cause the dilation of normal vessels and reduces the flow to area distal to the stenosis. This is the principal behind cardiac stress test.

22
Q

ECG signs of transmural vs subdendocardial MI?

A

transmural - ST elevation (STEMI), Q waves

subendocardial - NSTEMI = ST depressions

23
Q

1 cause of sudden cardiac death?

A

lethal arrhythmia (VTACH, VFIB)

24
Q

Diseases associated with sudden cardiac death

A

CAD, cardiomyopathy, heriditary ion channelopathies (long QT syndrome, Brugada syndrome)

25
Q

wavy fibers appear how soon after an MI?

A

4-24 hrs

26
Q

Biggest complication 1-3d post MI?

A

Postinfarction fibrinous pericarditis

27
Q

If one sees macrophages and mariginal granulation tissue, how many days post MI?

A

3-14d

28
Q

Major complications 3-14 days post MI?

A

free wall rupture –> tamponade
papillary muscle rupture –> mitral regurge,
IV septum rupture
LV pseudoaneurysm

29
Q

Most likely complication in the first 24hrs after an MI?

A

Arrythmia, HF, Cardiogenic shock

30
Q

What changes are seen in heart tissue in the first 4 hours post MI?

A

none

31
Q

First cardiac biomarker to rise post MI?

A

myoglobin

32
Q

Most specific cardiac biomarker post MI?

A

Cardiac troponin I

33
Q

Which cardiac biomarker is useful to determine if there was a re-infaction?

A

CK-MB, normally falls after 48hrs, so if high after that, sign of re-infarction

34
Q

Most common cause of death post MI?

A

Arrythmia

35
Q

V1 - V2 leads MI = which area of heart? artery?

A

anterior, over the septum - LAD

36
Q

V3- V4 leads MI = which area of heart? artery?

A

anterior side to the apex - distal LAD

37
Q

V5 - V6 leads MI = which area of heart? artery?

A

anterior side to lateral heart - LAD or L circumflex

38
Q

Leads I, aVL = which area of heart? artery?

A

lateral side - L circumflex

39
Q

Leads II, III, avF = area of heart? artery?

A

inferior heart - R circumflex

40
Q

What is Dressler syndrome?

A

Autoimmune, leads to fibrinous pericarditis

41
Q

When would a postinfarction fibrinous pericarditis occur post MI?

A

1-3 d post MI

42
Q

Which two complications of an MI can occur up to 14 days post MI?

A

Ventric free wall rupture, ventricular pseudoaneurysm formation (contained free wall rupture)

43
Q

Which complication can appear 2 weeks to months post MI?

A

True ventricular aneurysm

44
Q

When is the greatest risk for VSD post MI?

A

3-14 days post MI
