Abstract
Cardiovascular surgery is highly invasive, with a risk of postoperative coagulopathy due to various factors such as bleeding. Coagulopathy can progress to disseminated intravascular coagulation (DIC), which complicates various clinical conditions. However, no study to date has reported on DIC associated with cardiovascular surgery. Therefore, we investigated retrospectively the incidence, outcome, and risk factors of cardiovascular surgery-associated DIC in our institute. All patients who underwent cardiovascular surgery and were admitted to our intensive care unit between January 2016 and December 2017 were included in this study. The Japanese Association for Acute Medicine (JAAM) DIC score was calculated using our institute's database at the following time points: preoperatively, postoperative day 1 (POD1), POD3, and POD7. Data regarding surgery, 90-day mortality, and risk factors of DIC were also collected and analyzed by multiple regression. In total, 553 patients were considered eligible for analysis. Median age of eligible patients was 72 years, with a 90-day mortality rate of 1.4%. Patients with DIC at POD7 had higher Sequential Organ Failure Assessment (SOFA) score, preoperative JAAM DIC scores, and a longer anesthesia time than those without DIC. Female sex, preoperative DIC score, and anesthesia time were found to be risk factors for DIC.
