摘要
Coronary heart disease (CHD) is a common comorbidity in intensive care unit (ICU) patients, particularly in the elderly. This particular population may have worse conditions during sepsis, and it presents an overwhelming challenge for clinical practice. Previous studies suggested that patients with CHD have an increased risk of cardiovascular events, and low albumin concentration worsens the prognosis of patients with stable CHD. Hypoalbuminemia in patients with sepsis is common due to nutritional disorders, excessive consumption, and leakage. Albumin is a fluid often used for resuscitation in patients with sepsis. However, albumin infusion in patients with sepsis and CHD has rarely been studied. The effects and safety of albumin infusion in patients with sepsis and CHD remain unclear. Therefore, we collected medical information from Mimic-III (Mimic-III) and compared the all-cause mortality and cardiovascular mortality at 28- or 90-day between the albumin and non-albumin groups in septic patients with CHD. A total of 2,027 patients with sepsis and CHD were included in our study, with 405 in the albumin group and 1,622 in the non-albumin group. After propensity score matching (PSM), 350 pairs were included in our study. Improved survival benefits were found in the albumin group at the 28-day all-cause mortality compared with the non-albumin group (hazard ratio [HR], 0.54; 95% CI: 0.38–0.78; p = 0.0009). However, no difference was detected in the 90-day survival benefits (HR, 0.80, 95% CI: 0.60–1.06, p = 0.1207). Albumin infusion did not reverse cardiovascular mortality neither at 28th day nor at 90th day (cardiovascular mortality: 28 days, HR, 0.52, 95% CI: 0.23–1.19, p = 0.1218; 90 days, HR, 0.66, 95% CI: 0.33–1.33, p = 0.2420).
