The values were control group (t = 1.779,P = 0.087), and teprenone group (t = -0.891, P = 0.380).(6)Compared to control selleck inhibitor group, in the teprenone group had a lower incidence of gastric intestinal symptoms (P = 0.048). Patients in both groups had a negative result in fecal occult blood measure. Conclusion: (1) Teprenone can protect the gastric mucosa by increasing the production of PGI2 and ET-1. in patients But it doesn’t affect the blood level of TXA2. (2) Teprenone may have a effect of reduing the incidence of cardiovascular event in patients with coronary heart disease and don’t affect the anti-platelet effect of clopidogrel and aspirin. (3) Teprenone can reduce the incidence of gastric-intestinal symptoms

in these patients. The patients with low risk of gastric-intestinal haemorrhage have a low incidence of gastric-intestinal haemorrhage in the first month of dual anti-platelet therapy.

investigate the effect of chronic kidney disease on upper gastrointestinal bleeding (UGIB) in patients taking low-dose aspirin. Methods: 397 hospitalized patients with cardiovascular and/or cerebrovascular diseases taking LDA from May 2009 to April 2011 were retrospectively analyzed, the creatinine clearance (Ccr) was calculated followed the modified MDRD equation, and comparative analysis this website of the rate of UGIB in different stages of chronic kidney disease patients was performed. Results: A total of 397 patients taking the LDA

were rolled. there were 196 males and 201 females, with a average age of 68.7 ± 11.6years (age rang 24 to 96). 131 patients were <65years of age, and ≥65 years of age were 266 cases. Proportion of the stages of CKD 1 to 5 in male patients was 42.8%, 41.3%, 12.9%, 2.5%, 0.5%, while 45.9%, 40.8%, 11.2%, 1.5%, 0.5% in female patients, there was not significantly different stages of CKD between different the genders. Proportion of the stages of CKD 1 to 5 in patients <65years of age was 62.6%, 29.8%, 6.9%, 0.8%, 0%, while 35.3%, 46.6%, 14.0%, 2.6%, 0.8% in patients ≥65 years of age, Low-density-lipoprotein receptor kinase the proportion of CKD 3 to 5 in patients ≥65 years was significantly higher than patients <65 years of age (P = 0.019). Proportion of the stages of CKD 1 to 5 in 397 patients was 176 cases (44.3%), 163 cases(41.1%), 48 cases(12.1%),8cases(2.0%),2cases (0.5%). The rate of UGIB in CKD stage 1 was 2.3%, while 11.0% in CKD stage 2, 25.0% in CKD stage 3, 30% in CKD stage 4 and 5. The incidence of GI bleeding had positive correlation with the stage of CKD. The rate of UGIB in CKD stage 2, 3, 4–5 were significantly higher than patients in stage 1 (P < 0.05). Logistic regression analysis showed CKD stage 3–5 was an independent risk factor for LDA-related UGIB.
