A 63-year-old man presents to the Emergency Department after a fall, and he is found to have a broken hip. He undergoes surgical correction and recovers in the hospital. Before being discharged, he mentions to you that prior to the accident, he had not been able to exercise like before. For the past few months, he has experienced occasional chest pain with exertion that forces him to stop and rest. The pain goes away within 5 minutes of resting.

What should be performed before the patient is discharged from the hospital?

a. Pharmacologic stress test
b. Exercise stress test
c. Echocardiogram
d. Coronary angiography


Question 7#Print Question

A 59-year-old woman presents to your office with chest discomfort, jaw pain, and nausea. The symptoms occurred suddenly 2 hours ago and are getting worse. She has a history of poorly controlled hypertension, and she has a 30 pack-year smoking history. You decide to send her to the Emergency Department and order some initial tests, which are shown below.

  • Sodium 137 mEq/L
  • Potassium 4.9 mEq/L
  • Chloride 105 mEq/L
  • Bicarbonate 22 mEq/L
  • Blood urea nitrogen 21 mg/dL
  • Creatinine 1.3 mg/dL
  • Glucose 110 mg/dL
  • Troponin-I Positive

An ECG shows multiple T wave inversions and ST depressions in contiguous leads.

Which of the following is the most likely diagnosis? 

a. Stable angina
b. Unstable angina
c. Non-ST elevation myocardial infarction
d. ST elevation myocardial infarction


Question 8#Print Question

A patient suffers a myocardial infarction and undergoes percutaneous coronary intervention (PCI) with placement of a stent in the left anterior descending coronary artery. Later in the day, the patient develops blue discoloration of several toes on both of his feet. The following day his creatinine increases from 1.2 to 1.8.

Which of the following best represents the mechanism in this situation?

a. Plaque disruption in the aorta
b. Plaque rupture and thrombosis in distal arteries of the legs
c. Emboli from vegetations present on a cardiac valve
d. Antibodies developed against myocardial antigens released during infarction
e. Consumption of platelets and small vessel hemorrhage in the extremities


Question 9#Print Question

A 33-year-old homeless man is brought into the Emergency Department by police after they found him barely arousable on the street next to an empty bottle of vodka.

Which of the following is the most likely diagnosis?

a. Sinus tachycardia
b. Second-degree heart block
c. Atrial fibrillation
d. Wolff–Parkinson–White
e. Polymorphic ventricular tachycardia


Question 10#Print Question

A 68-year-old man is brought in by ambulance after losing consciousness. The patient’s wife was with him when he developed crushing chest pain while lying in bed. His wife went to get him some medication for the pain, but when she returned the patient was unconscious. Paramedics were called, and an ECG showed ST elevations in the anterolateral leads. His blood pressure is extremely low, and his extremities are cool. Which of the following best represents the hemodynamics in this type of shock? (Note: CO is cardiac output, JVP is jugular venous pressure, SVR is systemic vascular resistance, and SvO2 is mixed venous oxygen saturation.)
