Objective To investigate whether emergency percutaneous coronary intervention(PCI) could influence the BNP level in patients with ST-segment elevation myocardial infarction(STEMI).Methods We enrolled 193 patients who were admitted with STEMI.The BNP levels were measured at admission.All patients underwent routine clinical laboratory tests in the first day of hospitalization.Ninety-two patients underwent emergency PCI and the other 101 patients received conservative medicine treatment.The patients who had emergency PCI were divided into two subgroups according to the time between symptom onset and PCI started(ictus time 0-3 h,n=42;ictus time 3-6 h,n=50) for analysis.Results BNP levels were significantly lower in patients undergoing PCI when compared with conservative medicine treatment(261.0?410.9 ng/L vs 921.5?1126.7 ng/L,P

Objective To explore the effect of high-fat diet on IRS-1 and IRS-2 expressions of fatty liver in rat. Methods After the rats were fed a high-fat diet (n=7) and a standard chow(n=7) for 8 weeks, insulin sensitivity,lipid metabolism, TNF-α and hepatic mRNA and protein expressions of IRS-1 and IRS-2 were measured. Results Compared with the normal control, the high-fat diet group displayed the elevated levels of insulin resistance,FFA and TNF-α.Hepatic IRS-1 mRNA expression and IRS-1 protein content were reduced by 28% and 32%(P<0.01),respectively. Similarly, hepatic IRS-2 mRNA and IRS-2 protein content were also reduced by 30% and 27% (P<0.01), respectively. Conclusions High-fat diet results in a significant decrease in expressions of mRNA and protein of hepatic IRS-1 and IRS-2 in rats, which might be one of the molecular mechanisms of insulin resistance in liver steatosis induced by high-fat diet

BACKGROUND: Both pulse pressure (PP) and aortic stiffness are the predictors of coronary artery disease (CAD). The relationship between aortic PP and atherosclerosis may be bi-directional. Some investigations have tested the relationship between coronary arteriongraphy-diagnosed coronary heart disease and aorta pulse pressure (APP).OBJECTIVE: To observe the relationship between coronary atherosclerosis and APP in patients with primary hypertension.DESIGN: Case control observation.SETTING: Department of Cardiology, Xuanwu Hospital, Capital University of Medical SciencesPARTICIPANTS: A total of 300 patients with primary hypertension who received the treatment in the Department of Cardiology, Xuanwu Hospital, Capital University of Medical Science between July 2002 and January 2005. The patients were all untreated hypertensive patients who were referred for a first diagnostic coronary angiography. All of them met the diagnostic criteria of international hypertensive association. Secondary hypertension, myocardial disease, valvular disease of the heart (VDH), heart failure, liver and renal insufficiency and so on were excluded. The patients, 170 male and 130 female, were aged (61±11 )years. Informed consents were obtained from all the patients.METHODS: A total of 300 untreated hypertensive patients were recruited for a first diagnostic coronary angiography. According to whether having coronary artery disease (CAD), the patients were divided into CAD group (143 in total, 92 male, 64%) and non-CAD group (157 in total, 82 male, 52%). Informed consents were obtained from all the patients.The following data were collected: invasive intra-aortic systolic blood pressure (ASBP) and intra-aortic diastolic blood pressure (ADBP), extent of coronary artery disease, and basic clinical materials of the patients. All the observed index were expressed as Mean±SD. Independent sample t test was used in the comparison between two groups, and P < 0.05was set as significant difference.MAIN OUTCOME MEASURES: ASBP, ADBP and BP, ratio of stroke volume (SV), which reflects aortic stiffness, to aortic pulse pressure (APP); The number of branch and stegnotic extent of coronary artery disease (Cases with stegnotic extent < 50% were included in non-CAD group; Basic clinical indexes and routine biochemical indexes of patients after admission (including fasting blood glucose, serum creatinine, blood lipid and so on).RESULTS: The enrolled 300 patients with hypertension all participated in the result analysis. In the whole population, ASBP and PP were significantly higher in CAD group than non-CAD group [(150.3±26.5) vs. (145.6±23.3) mm Hg, P < 0.05;(77.1±22.7) vs. (70.4±19.3) mm Hg, P < 0.05)]. The ratio of APP to SV in CAD group was markedly higher than that in non-CAD group(1.20±0.44) vs. (0.96±0.33), P < 0.05]. Fasting blood glucose of patients in the CAD group was significantly higher than that in the non-CAD group [(1.38±0.27) vs. (1.08±0.28) mmol/L, P < 0.01]. Serum creatinine of patients in the CAD group was significantly higher than that of non-CAD group [(11.98±2.15) vs. (11.19±1.58) μ mol/L, P <0.01]. High-density lipoprotein cholesterol of patients in the CAD group was significantly lower than that in the non-CAD group [(0.54±0.13) vs. (0.62±0.18) mmol/L, P< 0.01].CONCLUSION: Atherosclerosis may further aggravate the aortic stiffness and then cause the increase of APP in patients with primary hypertension.

Objective Aim To investigate the effects of high-burden thrombus on outcomes of emergency percutaneous coronary intervention(PCI)in elderly patients with acute myocardial infarction.Methods Seventy-three elderly patients with ST elevated acute myocardial infarction(STEAMI)within 12 hours from onset received emergency PCI.They were divided into the high-burdern thrombus group(n=26)and the low-burden thrombus group(n=47)according to coronary artery angiography result.Mortality of 30 days,peak value of CK-MB,ejection fraction(EF)and TIMI flow after PCI were compared.Results The occurance of high-burden thrombus in infarct-related arteries was 35.6% which was more often common in right coronary artery.The rate of TIMI3 flow after PCI in high-burden thrombus group was lower than that of the low-burdn thrombus group.The 30-day-mortality and peak CM-MB level in the high-burden thrombus group was higher than that of the low-burden thrombus group.Conclusion High burden thrombus is an important factor of prognosis in elderly patients with acute myocardial infarction after emergency PCI.

Objective The aim of this study was to assess the distribution histogram of arm circumference (AC) in adult hypertensives in Beijing area, and to establish which size of cuffs is most appropriate in clinical practice. Methods We conducted a cross-sectional survey in a cohort of 424 (male 61.6%) consecutive hypertensives patients. Arm circumference was measured at the mid-point of the right upper arm. Subjects were stratified in three groups: group 1 with AC between 22-26 cm (small size), group 2 AC between 27-34 cm(medium size), and group 3 AC great than 34 cm (large size). Using AC of 32 cm as cutoff point, patients were subdivided as group A (AC

To evaluate the prevalence of impaired fasting glucose(TFG)in outpatients with essential hypertension and the influencing factors.Methods 1026 essential hypertensive outpatients aged 15-87 years[531 males and 495 females,mean age(51.6±12.5)years]who visited Xuanwu hospital between February 2004 and January 2007 were recruited in the study.Their medical history,blood pressure,height,weight,waist ircumferences(WC),hip circumference(HC),fasting plasma glucose(FPG),TC,TG,LDL-C,HDL-C were detected and analyzed.Results The abnormal rate of FPG in hypertensive outpatients was 38.5% and incidence of IFG was 30.5%.The differences of gender,systolic blood pressure,BMI,waist-to-hip ratio(WHR),TG,TC between the normal glucose group and the IFG group were significant Gender,family history of diabetes mellitus,TC and LDL-C enter into the logistic regression model(P<0.05).Conclusions The detection rate of IFG is high in hypertensive outpatients and it is related with gender,family history of diabetes mellitus and disorders of lipid metabolism.
