A 59-yeаr-оld wоmаn is brоught to the emergency depаrtment by ambulance complaining of acute onset shortness of breath and a “racing pulse” that began after a 16-hour flight for a business trip. Her past medical history is significant for Type 2 diabetes mellitus and for a hospitalization 2 months ago for a myocardial infarction, during which she received low-molecular-weight heparin following cardiac catheterization. Her current medications include metformin, aspirin, propranolol, and atorvastatin. On arrival, her temperature is 99.1°F (37.3°C), blood pressure is 112/74 mmHg, pulse is 96/min, respirations are 22/min, and oxygen saturation is 88% on room air. A chest radiograph is normal and an EKG shows sinus tachycardia. Lab results are obtained with the following results:Serum:Hemoglobin: 14.0 g/dLLeukocyte count: 6,800Platelet count: 260,000After appropriate imaging is performed, intravenous unfractionated heparin is started for treatment of possible pulmonary embolus and the patient is admitted to the hospital overnight. The next morning, the patient reports she is feeling better. Vital signs: T: 98.9°F (37.1°C), BP: 118/73 mmHg, HR: 88/min, RR: 15/min, and oxygen saturation is 97% on room air. Repeat lab results are as follows:Serum:Hemoglobin: 13.5 g/dLLeukocyte count: 7,200Platelet count: 118,000Which of the following statements about this condition is correct?
