ABSTRACT: To clarify the intestinal barrier function (IBF) state of patients with acute myocardial infarction-heart failure (AMI-HF), and to compare the therapeutic effects of rhubarb and Pantoprazole (proton pump inhibitor). Enrolled were 107 AMI patients from ICU, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology from May 2008 to April 2010. Of them, 47 AMI patients without HF were recruited as the control group, while 60 AMI-HF patients were randomly assigned to the rhubarb group (30 cases, treated by rhubarb + Pantoprazole) or the Pantoprazole group (30 cases, treated by Pantoprazole + routine treatment). All patients were treated till the 14th day of the onset. The fecal occult blood (FOB) test was performed daily. The occurrence of the digestive tract hemorrhage on the 14th day after onset was compared. The N-terminal pro-brain natriuretic peptide (NT-proBNP), serum D-lactic acid, plasma glutamine (Gln), endotoxin and cytokines [high sensitive C reaction protein (hsCRP), tumor necrosis factor-alpha (TNF-alpha), interleukin-10 (IL-10)], and heart function were compared among the three groups before and after treatment. There was no statistical difference in the case number of using aspirin, clopidogel, low molecular weight heparin, ACEI/ARB, statins, insulin, and antibiotics among the 3 groups. The case number of using beta-blocker was obviously lower in the two medication groups than in the control group (P < 0.05). The case number of using diuretics was obviously higher in the two medication groups than in the control group (P < 0.05). There was no statistical difference in the incidence of digestive tract hemorrhage (P = 0.413). Compared with the control group before treatment, Gin and ejection fraction (EF) were both lowered, NT-proBNP, D-lactic acid, endotoxin, hsCRP, TNF-alpha, and IL-10 increased in the two medication groups (P < 0.01). There was no statistical difference in each index between the two medication groups (P > 0.05). Compared with before treatment, NT-proBNP, D-lactic acid, endotoxin, hsCRP, TNF-alpha, and IL-10 decreased in the Pantoprazole group (P < 0.01), and no obvious change in Gin or EF was found (P > 0.05). Gin and EF increased in the rhubarb group after treatment, and they were higher than those of the control group. Blood NT-proBNP, D-lactic acid, endotoxin, hsCRP, TNF-alpha, and IL-10 decreased in the rhubarb group after treatment, showing statistical difference when compared with the control group (P < 0.01, P < 0.05). Impaired IBF and endotoxemia existed in AMI-HF patients. Rhubarb not only could prevent the digestive tract hemorrhage, but also could reduce endotoxemia, inhibit inflammatory reactions, and improve the heart function through ameliorating the IBF.
