Nuclear Cardiology Sample Questions:

Question 1

A 75-year-old male with a history of coronary artery disease status posts stenting of the LAD presents with new onset chest pain ongoing for the last two months. Pain is exertional in nature, improving with rest and nitroglycerin. He states having been compliant with his medication. A pharmacological nuclear stress test is ordered. Findings are most consistent with:

A) Normal
B) Single vessel LAD disease
C) Single vessel LCX disease
D) Single vessel RCA disease
E) Multivessel disease

Answer
E) Multivessel disease


Explanation
Answer: (E) Multivessel disease. Explanation: There is a global decrease in intensity in the stress images as opposed to the rest images. Transient ischemic dilatation is also present. Finally, there is a large perfusion defect in the left circumflex distribution. Taken together these findings point towards multivessel disease. This patient required bypass surgery following repeat angiography demonstrating multivessel proximal disease.


Question 2

A 35-year old man presents with progressive shortness of breath of 2 months duration. His history is significant for severe alcohol abuse remotely and a family history of a brother who died at age 28 of "heart problems." He was physically active until about 2 years ago. He can now walk less than 1 block on the level and is in NYHA class 3 symptomatically. He denies any changes in medications, travel, exposures, or substance abuse in the prior 2 years. His transthoracic echocardiogram demonstrates an LVEF of 15% but was limited due to poor windows. His pharmacological stress test is shown below. Pertinent parameters from the test include an EDV of 200 mL, ESV of 180 mL, and TID ratio of 1.00. The most likely cause of his dyspnea is:

A) Ischemic cardiomyopathy
B) Dilated cardiomyopathy
C) Pulmonary hypertension
D) 12.5mg hydrochlorothiazide tablet
E) Non-cardiac in origin

Answer
B) Dilated cardiomyopathy


Explanation
Answer: (B) Dilated cardiomyopathy. Explanation: The perfusion scan shows a large heart with normal perfusion. The absence of perfusion defects makes the diagnosis of ischemic cardiomyopathy highly unlikely, except in the very rare case of balanced ischemia. This would be rare in a 35 year old, though not unheard of. In pulmonary hypertension, the left ventricular size would be normal, but there would be prominent uptake of tracer in the right ventricle and this structure would demonstrate significant tracer uptake. The stem mentions that the patient's brother died at a young age of "heart problems" making a non-cardiac cause also highly unlikely. The EDV of 200 mL is beyond the upper limit of normal for EDV and the normal perfusion make a dilated cardiomyopathy the most likely diagnosis.
