ABSTRACT
Objective To observe the relationship between CYP2C19 gene polymorphisms and major adverse cardiovascular events in the patients of acute coronary syndrome (ACS) who accepted percutaneous coronary intervention (PCI) in Han population from Dalian. Methods A total 809 cases with ACS who had undergone PCI in the cardiology department of Dalian Municipal Central Hospital from Janurary 2012 to Janurary 2014 were selected,Among 809 cases of ACS,there were 178 cases of acute ST segment elevation myocardial infarction (STEMI),105 cases of acute non ST segment elevation myocardial infarction (NSTEMI) and 526 cases of unstable angina. The patients were divided into three groups according to their CYP2C19 genotype.CYP2C19 genotype (*1/*1) were classified as extensive metabolizers (EM group), CYP2C19 genotype (*1/*2、*1/*3) were classified as intermediate metabolizers (IM group) and CYP2C19 genotype (*2/*2、*3/*3、*2/*3) were classified as poor metabolizers (PM group). The occurrence of major adverse cardiovascular events at least 24 months was observed. Results Seven hundred and ninety patients finished the follow-up at least 24 months, 19 patients lost in follow-up, 350 cases (43.2%) were CYP2C19 (*1/*1),318 cases (39.3%) were CYP2C19(*1/*2), 42 cases(5.2%) were CYP2C19 (*1/*3),77 cases (9.5%) were CYP2C19 (*2/*2), 21 case(2.2%)were CYP2C19 (*2/*3), and 1 case (0.1%) was CYP2C19(*3/*3), 350 cases (43.2%) were classified as EM group, 360 cases (44.5%) were classified as IM group, and 99 cases(12.2%)were classified as PM group. No significant difference in age, gender, hypertention, diabetes mellitus, smoking was shown among three groups (P > 0.05). The rate of MACE were 3.3% , 8 cases had target lesion revascularization(EM group 3 cases, IM group 3 cases, PM group 2 cases), 2 cases had non-fatal myocardial infarction (IM group 1 case, PM group 1 case), 15 cases were died(EM group 6 cases, IM group 7 cases, PM group 2 cases), 1 case had subacute stent thrombosis in IM group. The rates of MACE were higher in PM group (5.1%) than those in EM group(2.65%) and IM group (3.41%) , but there was no significant difference in three groups (P>0.05). There was no significant difference in the rate of target lesion revascularization , thrombus in stent, non- fatal myocardial infarction and death among three groups(P > 0.05). Conclusions There is no significant correlation between CYP2C19 gene polymorphism and long-term prognosis in patients with ACS who accepte PCI treatment in Han population from Dalian.
ABSTRACT
OBJECTIVED: To explore the prevalence and risk factors of type 2 diabetes mellitus (T2DM) and impaired glucose regulation (IGR) in Zhangzi Island of Dalian, additionally to provide a better understanding of further intervention. METHODS: A cross-sectional study was performed in 907 residents aged over 18 years from Zhangzi Island of Dalian. The questionnaire, physical measurement, food intake frequency and previously dietary investigation were used in the analysis. Simultaneously, a series of biochemistrical and immune index was measured, including blood uric acid, blood sugar, total cholesterol, triacylglycerol, as well as serum insulin.RESULTS: The recovery rate of questionnaire was 95.9%, which demonstrated that the prevalence rates of T2DM and IGR in Zhangzi Island were 11.36% and 37.38%, there was no significant differences between males and females (P > 0.05). Only 29.13% of the people with T2DM were aware of the condition. The prevalence of DM and IGR were increased significantly with age (P < 0.01). The results of the logistic regression showed that age, education, alcohol drinking and hypercholesteremia were the risk factors of IGR. In addition, age, education, hypercholesteremia, hypertriglyceridemia, body mass index and hypertension were the important risk factors for the development of DM. CONCLUSION: The prevalence rates of T2DM and IGR in Zhangzi Island of Dalian are high with a low awareness. Health promotion on lifestyle changes may help to increase the public awareness and reduce the prevalence.
