Question 116#Print Question

A 66-year-old man hospitalized for an NSTEMI was successfully treated with DES for a subtotal lesion of the proximal LAD.

What is the recommended minimal duration of dual antiplatelet therapy according to the 2011 American College of Cardiology (ACC)/American Heart Association (AHA) guidelines on PCI?

a. 1 month
b. 3 months
c. 6 months
d. 12 months
e. 24 months


Question 117#Print Question

A 54-year-old man known for smoking and hypertension is admitted to the emergency department with an NSTEMI. Echocardiography reveals abnormalities in the acute lateral wall motion. The angiogram (Fig. below)

shows

a. Severe LCX stenosis
b. Severe left main trunk stenosis
c. Severe LAD stenosis
d. Severe RCA stenosis
e. No significant coronary artery stenosis


Question 118#Print Question

A 75-year-old man has been treated 1 month ago with a DES in the proximal LAD for ACS. At that time he did not mention that he was supposed to require surgery for debilitating knee arthritis.

Which of the following statements is correct?

a. The recent implantation of a DES is not problematic as long as aspirin can be continued during surgery
b. The recent implantation of DES is not problematic as long as clopidogrel can be continued during surgery
c. The recent implantation of DES is not problematic as long as aspirin and clopidogrel can be continued during surgery
d. Discontinuation of dual antiplatelet therapy followed by noncardiac surgery in the first few weeks following stent implantation is associated with increased ischemic cardiac events with both DES and BMS
e. Discontinuation of dual antiplatelet therapy followed by surgery in the first few weeks following stent implantation is problematic with DES but not BMS


Question 119#Print Question

A 66-year-old woman had a second-generation DES implantation after an acute MI. What is the correct statement?

a. To prevent DES late thrombosis, dual antiplatelet therapy with aspirin and clopidogrel is recommended for 3 years
b. Based on the results of the CHARISMA (Clopidogrel for High Atherothrombotic Risk and Ischemic Stabilization Management, and Avoidance) trial, aspirin and clopidogrel should be administered for at least 2 years in patients with an acute coronary event, independently of the implantation of a DES
c. At 1 year, clopidogrel may be discontinued but if the patient is on lowdose aspirin, the dose of aspirin has to be increased to 325 mg/day
d. In patients who have already suffered a stent thrombosis dual antiplatelet therapy may be extended long term, although currently there are no data to support this strategy
e. Following DES implantation, aspirin should be discontinued at 12 months and clopidogrel administered indefinitely


Question 120#Print Question

A 60-year-old man known for current smoking is admitted to the emergency department for prolonged typical chest pain. The 12-lead ECG is shown in Figure below.

What is the most likely finding at the coronary angiography?

a. Occlusion of the first marginal branch of the left circumflex coronary artery
b. Occlusion of the proximal left anterior descending coronary artery
c. Occlusion of the dominant RCA
d. Occlusion of the left main trunk
e. Occlusion of the first diagonal branch
