In the post-operative acute stage, carperitide showed cardiorenal protective effects that prevented post-operative cardiac events and initiation of dialysis. Thus, perioperative infusion of low-dose carperitide may have a significant role in management of patients with renal dysfunction undergoing on-pump CABG. (Effectiveness of hANP for Cardiac Surgery in Patients With Moderate to Severe Preoperative Renal Dysfunction Without Dialysis [NU-HIT for CRF]; UMIN000001462).

Emergency surgery for octogenarians with acute aortic dissection showed acceptable mortality. However, families had to take responsibility for patients who experienced unconsciousness, had dementia, or became bedridden. It is important to have consensus between the family and surgeons about emergency surgical treatment for octogenarians.

The fibrosis of tissue associated with age is believed to be closely related to the occurrence of atrial fibrillation after coronary artery bypass grafting. This study suggests that the preoperative values of atrial natriuretic peptide, angiotensin II, the sialylated carbohydrate antigen KL-6, hyaluronic acid, and pyridinoline cross-linked telopeptide of type I collagen in the blood are useful as a new index for the occurrence of atrial fibrillation after coronary artery bypass grafting.
