摘要

Background

Flash pulmonary edema is a medical emergency in which immediate recognition can be life-saving, especially when patients do not have typical clinical manifestations.

Case presentation

Herein, we report the case of a 56-year-old man who was admitted to the hospital due to paroxysmal palpitations for one week. His pro-B-type natriuretic peptide (BNP) level and left ventricular ejection fraction (LVEF) were normal, and he had no obvious symptoms of dyspnea. However, a CT scan of the chest indicated flash pulmonary edema. Through anti-heart failure treatment, the lung lesions improved.

Results

The patient was diagnosed with HFpEF caused by paroxysmal supraventricular tachycardia. The abnormal imaging manifestations in the lung were due to flash pulmonary edema, which was caused by acute heart failure.

Conclusion

Flash pulmonary edema is a medical emergency in which immediate recognition can be life-saving, especially when patients do not have typical clinical manifestations.
