ABSTRACT
It is unclear whether activated partial thromboplastin time (APTT) is predictive of survival in acute pancreatitis(AP) patients. Our study aimed to investigate the relationship between APTT and short-term prognosis in AP. From the Medical Information Mart for Intensive Care (MIMIC)-IV database, a total of 844 patients with AP were randomly divided into the training cohort (n=591) and the validation cohort (n=253) at a ratio of 7:3. Based on their APTT values, the patients were divided into the normal and high groups. The primary outcome of this study was 30- and 60-day survival. Kaplan-Meier survival analysis and Cox regression models were used to analyze associations between groups and outcomes. The training and validation cohort matched well on all parameters(P > 0.05). In terms of 30- and 60-day survival, Kaplan-Meier survival curves from both training and validation cohorts demonstrated a lower survival probability for patients in the high APTT group than the normal group(Log-rank P <0.05). In the training cohort, patients in the high APTT group had a statistically significantly higher risk of death than those in the normal group after controlling for possible confounders in Cox regression(P < 0.05). For the high APTT group, the hazard ratios (95% CI) were 1.63(1.10, 2.61) (P=0.035) and 1.49(1.01, 2.38) (P=0.041), respectively. APTT performed as well as BISAP, Ranson, APACHE II models in predicting 30- and 60-day survival in patients with AP. The results above have been verified in the validation cohort. Prolonged APTT in patients with AP may increase the risk of short-term death.
