Objective To investigate the difference between Asia-Pacific Colorectal Screening (APCS) scoring system and colorectal cancer sequential screening criteria issued by the Health Ministry of China (China sequential criteria) in the evaluation of high-risk colorectal neoplasm in patients undergoing coronary artery angiography (CAG) examination.Methods The data of 870 patients aged from 40 to 74 who underwent CAG examination were retrospectively analyzed.The measurement data were analyzed by t test and the count data were aralyzed by x2 test.Results There were 72 patients aged from 40 to 49 years old.Among them,eight patients were stratified as high-risk population according to the Chinese sequential criteria; however there was no high-risk population by APCS.There were 798 patients aged from 50 to 74 years old.There were 460 patients stratified as high-risk population by APCS.The percentage of CAG negative group (34.7％) was significantly lower than that of the coronary artery disease (CAD) group (68.0％,x2 =77.74,P＜0.01).According to the Chinese sequential criteria,and there were 134 patients stratified as high-risk population,and there was no significant difference between the CAG negative group (17.7 ％) and the CAD group (16.4％,P＞0.05).Among the patients aged from 50 to 74 years old without family history of colorectal cancer in first-degree relatives,72 cases (29.0％) of the CAG negative group and 316 cases (57.5％) of the CAD group were stratified as high-risk according to APCS,however not stratified as high-risk by the Chinese sequential criteria.About 90.5 ％ (351/388) of them were male smokers.According to APCS,30 cases (12.1％) of the CAG negative group and 32 cases (5.8％) of the CAD group were stratified as middle-risk population,however stratified as high-risk population by the Chinese sequential criteria.About 75.8％ (47/62) of them were female non-smokers.Conclusions The percentage of patients stratified as high-risk population by APCS was higher than that by the Chinese sequential criteria.In patients aged from over 50 to 74 years old and without family history of colorectal cancer in first-degree relative,APCS maybe overestimated the risk degree of colorectal neoplasm in male smokers and underestimated the risk degree in female non-smokers.

Objective To evaluate previous gastroscopy before percutaneous coronary intervention (PCI) for the risks and benefits of concomitant use of proton pump inhibitors (PPIs) after PCI in patients with non-acute coronary syndrome (non-ACS).Methods The data of 673 non-ACS patients who underwent PCI with stenting were retrospectively analyzed.They were divided into concomitant use of PPIs group and non-PPIs group,then subdivided into high-,moderate-and low-risk groups according to risk factors associated with adverse upper gastrointestinal (GI) events.The incidences of adverse cardiovascular events and adverse upper GI events were compared among groups.Findings of previous gastroscopy were also included.Results Only 82 patients (12.2％) underwent gastroscopy within 5 years before PCI,of whom,27 (32.9％) were diagnosed as having peptic ulcer,and 55.6％ (15/27) of whom were in concomitant use of PPIs.Compared with the non-PPIs group,the rate of adverse cardiovascular events in the concomitant use of PPIs group was significantly higher (22.6％ vs.8.9％,P ＜0.01),and the highest rate (41.7％) was in the high-risk group.However,the corresponding rate of adverse upper GI events was the lowest (4.2％).In the moderate-risk group,90.5 ％ (344/380) of patients were older than 65 years with concomitant use of NSAIDs.The rate of gastroscopy within 5 years before PCI in these patients was remarkably lower than that in patients who had the history of upper GI disease with concomitant use of NSAIDs (concomitant use of PPIs group 14.1％ vs.54.5％ ; non-PPIs group 7.5％ vs.28.0％ ; P ＜ 0.01).In the concomitant use of PPIs group,the rate of adverse cardiovascular events in the former was notably higher than that in the latter (20.5％ vs.9.1％,P ＜0.01),but the rate of adverse upper GI events within 1 year after PCI were similar (9.0％ vs.9.1％).Conclusion Previous gastroscopy before PCI could provide the baseline information of upper GI disease,which may be helpful for the evaluation of concomitant use of PPIs after PCI so as to decrease the incidence of adverse cardiovascular events.Special attention should be paid to those patients older than 65 years in the moderate-risk group and concomitant use of NSAIDs.
