Old female with chest pai...

A 60-year-old female presented with chest pain followed by dyspnea. In the emergency department, she was drowsy and hypotensive, exhibiting acute pulmonary edema and LBBB on the ECG. She subsequently arrested in asystole but achieved return of spontaneous circulation (ROSC) after 5 minutes and was taken to the cath lab. Non-obstructive coronary artery disease (CAD) was found, with negative cardiac troponin T (cTnT). Given this clinical scenario, would you recommend drainage based on the echocardiogram findings?
