71-Year-Old Man Presenting With Postoperative Chest Tightness
A 71-year-old man with a medical history of acute myeloid leukemia in remission after chemotherapy and stem cell transplant, chronic graft-versus-host disease, type 2 diabetes mellitus on insulin, and high-grade invasive adenocarcinoma of the transverse colon presented for laparoscopic right colectomy. Preoperative evaluation revealed no cardiovascular abnormalities, with an electrocardiogram (ECG) showing only first-degree atrioventricular (AV) block and a transthoracic echocardiogram showing normal systolic function, with an ejection fraction of 67%, 6 months before his presentation.
