polymorphonuclear leukocytes, microabscesses, and multinucleated giant cells may be presen
Treatment options for thromboangiitis obliterans? ...Answer Is...smoking cessation most important!
cilostazol (PDE 3 inhibitor) has vasodilator properties (alleviated symptoms)
if raynauds also present, CCB (nifedipine)
what heart failure treatment provides a benefit of reduction in morbidity and mortality? ...Answer
Is...ACE inhibitors
beta blockers can also reduce M&M
diuretics have no reduction in mortality
how would you manage a patient with a MI in the setting of cocaine use? ...Answer Is...benzodiazepine
early
no beta blockers
If PCI cannot be done for a STEMI patient within 120 minutes, what should be done? ...Answer
Is...fibrolytic therapy

fibrolytic therapy can be used up to 12 hours of symptoms
If you suspect an acute limb ischemia due to arterial embolism, what imaging should you get? ...Answer
Is...catheter-based arteriography (digital subtraction arteriography) provides the most useful
information. can also help with treatment
can help distinguish between thrombosis and embolus
where are arterial emboli often found? ...Answer Is...lower extremities more common than upper
extremities
The common femoral, common iliac, and popliteal artery bifurcations are frequent locations
majority originate in the heart
fun fact: Compared with thromboemboli, atheroemboli are less likely to produce symptoms of acute
limb ischemia
how would you work up a patient with treatment resistant hypertension that you suspect a secondary
cause? ...Answer Is...24-hour ambulatory monitoring (to ensure not white coat)
medical hx (assess adherence to meds, other meds)
physical exam (look for abominal/renal bruits)
labs (electrolytes, glucose, creatinine, UA)

how should you educate a patient with AAA on exercise? ...Answer Is...Patients should be counseled that
moderate physical activity such as running, biking, swimming, hiking, or sexual activity and activities
such as gardening, golfing, and horseback riding do not precipitate AAA rupture
Moderate physical therapy may also limit aneurysm expansion. In experimental aneurysms, increased
aortic blood flow appears to inhibit AAA expansion
However, heavy lifting, especially while holding the breath, and other activities that lead to Valsalva
transiently induce significant increases in blood pressure and should be avoided
gold standard for dx renal artery stenosis? what can be used to monitor disease progression? ...Answer
Is...renal arteriography
But really a spiral CT angiography is very useful and probably more likely done first
duplex doppler US can be used to monitor disease progression
