Review Question - QID 109227

A 50-year-old female comes to the emergency department with sudden onset left-sided calf pain starting 20 minutes ago. Her past medical history is notable for diabetes, hypertension, and chronic atrial fibrillation controlled on an anti-arrhythmic. Upon arrival to the emergency department, her blood pressure is 150/91 mmHg, pulse is 100/min, and respirations of 22/min. Examination of the leg reveals a pale left calf with diminished dorsalis pedis and posterior tibial pulses. Prompt intervention relieves the patient’s symptoms. Which of the following, if seen microscopically, would indicate that her calf myocytes are more likely to recover without permanent damage?
