A 76-year-old male with a medical history significant for heart failure with reduced ejection fraction (HFrEF) of 30% to 35%, COPD, and iron deficiency anemia is admitted for acute dyspnea on exertion with wheezing. CBC reveals a hemoglobin of 6.2 g/dL and hematocrit of 20%. A packed red blood cell transfusion is initiated. Seven hours later, the patient developed worsening dyspnea with an oxygen saturation of 72% on room air. The temperature is 99.2 °F (37.3 °C). Lung sounds show rales bilaterally. The neck veins are distended, and the patient develops hypertension. CBC shows a WBC of 10,100 and a platelet count of 237,000. What is the most likely diagnosis?

A 42-year-old woman presents to the emergency department with complaints of recurrent shortness of breath for the past 2 weeks. She reports shortness of breath whenever she goes on her morning run.
