发帖前你不检查一下？ question 2 and 5重复啦。
哪里的board question? step 3? CK? ABIM? ABMS for cardiology?:-)

发帖数: 182 | 9 非常谢谢前辈的答复。
第5题虽然感觉diabetic是个高危因素，但是考虑95% occlusion of left anterior
first diagonal coronary artery，说明stenosis developing slowly, and
collateral branches have been developed.
所以不知和C哪个更高危。
3我猜是C。刚看了EKG书，Unusually prominent QRS voltage in leads II, III and
aVF 我的理解是lead I upward, aVF downward, 这时，left axis deviation,所以
left ventricular hypertrophy duo to left hear failure。
再次多谢。 |

发帖数: 1220 | 10 3. Unusually prominent QRS voltage in leads II, III and aVF
A. High output heart failure
B. Diastolic heart failure
C. Left sided failure
D. Acute heart failure
E. Cor pulmonale
II III aVF leads refer to right coronary artery or right heart, so answer
should be
Cor pulmonale? |

angiography?
A. Contraindicated in the setting of acute MI (no)
B. Associated with 8-10% risk of coronary injury and catheter-associated
MI (I guess yes)
C. Does not require contrast material or radiation exposure (no)
D. Should be done within 6 hours of STeMI, if available (<90 min)
E. Not as effective as thrombolytic/fibrinolytic therapy (more effective)
I chose B |

A. Less likely than caucasians to have low-renin HTN
B. More likely than caucasians to have expanded intravascular volume
C. Less lkely than Cambodian Hmong to respond to diuretics
D. More likely than hispanics to respond to Milrinone
E. More likely than Norwegians to respond to Lutefisk
I chose B
blacks are more sensitive to salts/H2O, easy to have HTN, response well to
diuretics |

发帖数: 1220 | 13 5. Which patient faces the highest risk of acute coronary occlusion?
A. 18 year old high school student with heart murmur and history of
exertional syncope
B. 63yo diabetic with 95% occlusion of left anterior first diagonal
coronary artery
C. 52yo with 30% occlusion and unstable plaque, normal stress-thallium
test last week
D. 61yo male with past history acute MI and akinetic interventricular
septum
E. 85yo WM with irregular rhythm and harsh blowing systolic murmur
B
Odds do not favor A. 18YO or E. 85YO, too young to die or should be dead
already if having highest risk...C. 30% occlusion less likely to block?
between B and D, diabetic = previous MI, risk wise...63YO >61YO, 95%
occlusion is ticking bomb, akinetic septum (dead tissue?) has increased risk
of thromboembolism, but most likely systemic? |

发帖数: 1220 | 15 did some search:
myocardial troponin can also be released in the setting of increased
membrane permeability (4). With increased membrane permeability, smaller
troponin fragments could be released into the systemic circulation. In this
setting, myocyte damage may not be permanent and necrosis does not occur. |

D. Presence of lupus anticoagulant (yes)
E. Hypercoagulability (yes)

helpful, the one most likely to confirm the source of her headache is

wild guess A, this is the same one as No 3, right? |
