ABSTRACT

Objective@#To observe the etiology, comorbidities, clinical features and treatment patterns of hospitalized patients with heart failure (HF) in China.@*Methods@#Data were collected prospectively on hospitalized patients with HF who were enrolled in China Heart Failure Center Registry Study from 169 participating hospitals from January 2017 to August 2018. In this cross-sectional study, patients were stratified by left ventricular ejection fraction (LVEF) category: heart failure with reduced ejection fraction (HFrEF, LVEF<40%); heart failure with mid-ranged ejection fraction (HFmrEF, 40%≤LVEF<50%) and heart failure with preserved ejection fraction (HFpEF, LVEF≥50%). The clinical data were collected, including demographic information, diagnosis, signs, electrocardiogram, echocardiography, laboratory tests, and treatment.@*Results@#A total of 31 356 hospitalized patients with HF were included, 19 072 (60.8%) were males and the average age was (67.9±13.6) years old. The common causes of HF were hypertension (57.2%), coronary heart disease (54.6%), dilated cardiomyopathy (14.7%), valvular heart disease (9.2%). The common complications were atrial fibrillation/atrial flutter (34.1%), diabetes (29.2%), and anemia (26.7%). 32.8% of patients had a history of hospitalization for HF within the previous 12 months. There were 11 034 (35.2%) patients with HFrEF, 6 825 (21.8%) patients with HFmrEF and 13 497 (43.0%) patients with HFpEF. Compared with patients with HFpEF, patients with HFrEF had a lower systolic blood pressure ((124.7±21.1)mmHg(1 mmHg=0.133 kPa) vs. (134.9±22.9)mmHg), faster heart rate ((85±19) beats/minutes vs. (81±19)beats/minutes), and higher percentage of New York Heart Association (NYHA) class Ⅳ, smoking, alcohol, left bundle branch block, and QRS time≥130 ms, and higher levels of blood uric acid, BNP, and NT-proBNP (all P<0.05). Compared with patients with HFmrEF and HFrEF, patients with HFpEF were older, more women, and higher comorbidity burden including hypertension, atrial fibrillation/atrial flutter, anemia and chronic obstructive pulmonary disease (all P<0.05). HFmrEF took a mid-position between HFrEF and HFpEF in age, gender, heart rate, systolic blood pressure, hypertension, atrial fibrillation/atrial flutter, anemia, and chronic obstructive pulmonary disease (all P<0.05). Patients with HFmrEF had the highest proportion of coronary heart disease, myocardial infarction and percutaneous coronary intervention (all P<0.05). During hospitalization, loop diuretics were used in 90.2% of patients, and intravenous inotropics were used in 20.4% of patients. The use of ACEI/ARB/ARNI, β blockers and aldosterone receptor antagonists at discharge were 71.8%, 79.1% and 83.6% in HFrEF and 69.9%, 75.5% and 72.4% in HFmrEF, respectively. The use of digoxin at discharge was 25.3% (HFrEF 36.7%, HFmrEF 23.1%, HFpEF 17.0%). The rates of cardiac resynchronization therapy and implantable cardioverter defibrillator in HFrEF were 2.7% and 2.1%.@*Conclusions@#Among the hospitalized patients with HF in China, coronary heart disease and hypertension are the mostly prevalent causes. HFpEF accounts for a large proportion of hospitalized patients with HF. HFrEF, HFmrEF and HFpEF have different etiology and clinical features. In real-world, there are still large gaps in the effective application of the guideline recommended therapies to HF patients, especially the non-pharmacological therapy option, which needs to be improved further in China.

ABSTRACT

Objective To investigate the intervention effect of CD147 on learning and memory ability in rat model of Alzheimer's disease. Methods A total of 60 healthy Sprague-Dawley rats were randomly divided into sham operation group, model group and CD147 group, 20 rats in each group. All of the rats were anesthetized with intraperitoneal injection of 10%chloral hydrate (0.3 g/kg). The rats in the model group and the CD147 group were injected with Aβ1-40 (10μg) in the bilateral hippocampal CA1 regions, while the rats in the sham operation group were injected with the same amount of saline at the same sites. After 48 h, the rats in CD147 group were injected with CD147 cDNA in the bilateral ventricles, while the rats in model group and sham operation group were injected the same amount of saline at the same sites. Morris water maze test was used to detect the ability of learning and memory of rats. The expressions ofβamyloid protein (Aβ) andγ-secretase were detected by Western blot assay. Results The escape latency was significantly longer in model group than that of sham operation group, while which was significantly lower in CD147 group than that of model group (P<0.05). The number of times across the platform and the time of staying on platform were significantly lower in model group than those of sham operation group, while which was significantly higher in the CD147 group than that of model group (P<0.05). The expressions of Aβandγ-secretase were increased significantly in model group compared to those of sham operation group, while which were significantly decreased in CD147 group compared with those of model group (P<0.05). Conclusion Exogenous CD147 can significantly improve the learning and memory ability of AD rats, and its specific mechanism may be related to regulating the activity ofγ-secretase and down regulating the expression of Aβ.

ABSTRACT

Acute myocardial infarction (AMI) has a high mortality rate and poor prognosis for patients. The primary causes of death are arrhythmia and heart failure. For patients admitted because of myocardial infarction, various risk evaluations are initiated to foresee possible complications. The thrombolysis in myocardial infarction (TIMI) risk score, which can be used to predict the prognosis and the need for revascularisation, is the most convenient and commonly used system, but is inadequate for AMI patients on admittance. Fragmented QRS (fQRS) has been shown to be a valuable electrocardiographic (ECG) index for predicting the prognosis of patients with coronary heart disease. Also, fQRS is considered to predict an increased likelihood of a poor outcome and mortality in patients with coronary artery disease (CAD), even for some successfully revascularized AMI patients. So what would happen if fQRS and the TIMI risk score were combined? This study focused on the investigation of the short-term prognostic value of fQRS combined with the TIMI risk score for patients with AMI.

ABSTRACT

Objective@#To evaluate the difference of plasma myeloperoxidase (MPO) level in different types of acute coronary syndrome (ACS) patients, and the value of baseline MPO level in predicting short-term and long-term outcomes in patients with ACS.@*Methods@#The study cohort was derived from "the 12th Five-Year" National Science and Technology Support Program Project "Study on Comprehensive Intervention and Prognosis of Acute Coronary Syndrome" . We enrolled all hospitalized ACS patients who were enrolled in "the 12th Five-Year" cohort from January 1, 2011 to December 31, 2013. A total of 630 patients from 20 centers were enrolled. According to the diagnosis, the patients were divided into two groups: ST-segment elevation myocardial infarction (STEMI) group and non-ST-elevation acute coronary syndrome (NSTE-ACS) group. Plasma levels of MPO were measured by ELISA method. Cardiovascular events in the hospital were recorded. All patients were followed-up by telephone, follow-up ended December 31, 2015. The occurrence of major adverse cardiovascular events (MACE, defined as cardiac death, recurrent myocardial infarction, unscheduled coronary revascularization procedure and stroke) and all-cause death were recorded. Logistic regression analysis and Cox regression analysis were used to evaluate the predictive value of baseline MPO levels obtained during hospitalization and the long-term outcomes of ACS patients.@*Results@#A total of 597 ACS patients were enrolled in final analysis. Level of plasma MPO in STEMI patients was significantly higher than that of NSTE-ACS patients (34.02(19.31, 67.87) μg/L vs. 27.25(16.69, 52.92) μg/L, P=0.028) . MPO was not related to the in-hospital cardiovascular events (OR=0.797, 95%CI 0.366-1.737, P=0.569). Follow up was completed in 476 patients, median follow-up time was 796 (32, 1 816) days. There were 23 all-cause deaths and 51 MACE. Plasma MPO level was not an independent predictor for all-cause death (HR=1.434, 95%CI 0.502-4.100, P=0.501) and MACE (HR=1.271, 95%CI 0.662-2.442, P=0.471).@*Conclusion@#In hospitalized ACS patients, level of plasma MPO was significantly higher in STEMI patients than in NSTE-ACS patients, but MPO could not predict the short-term or long-term outcomes in patients with ACS.

ABSTRACT

AIM:To elucidate the association between chronic kidney injury and interleukin-33 (IL-33;an alarmin)/suppression of tumorigencity 2 (ST2) in patients with systemic lupus erythematosus (SLE).METHODS:Serum levels of IL-33 and soluble ST2 (sST2) were assessed by ELISA in 50 SLE patients and 30 healthy controls (HC).RESULTS:The levels of IL-33 and sST2,and IL-33/sST2 ratio were significantly higher in SLE patients than those in the HC.The IL-33 and sST2 levels were positively associated with SLE disease activity index (SLEDAI),erythrocyte sedimentation rate (ESR),proteinuria and triglyceride,but negatively associated with complement C3.IL-33/sST2 ratio was positively associated with SLEDAI and estimated glomerular filtration rate (eGFR).Independent explanatory variables associated with high IL-33/sST2 included chronic kidney disease (CKD) staging and albumin (R2 =0.442),especially CKD staging.CONCLUSION:Elevated serum sST2 and IL-33 levels in SLE patients are correlated with disease activity and risk factors of kidney injury.IL-33/sST2 ratio may serve as a potential biomarker for chronic kidney injury in SLE patients.

ABSTRACT

Objective@#The aim of this study was to investigate the association of both peripheral and central systolic blood pressure (pSBP and cSBP) with urinary albumin-to-creatinine ratio (UACR) in a community-based population in Beijing.@*Methods@#A total of 3 479 Chinese subjects with questionnaire, UACR, pSBP, and cSBP data available were included from an atherosclerosis cohort of Peking University First Hospital in Shijingshan District, Beijing followed up from April to July in 2014. Multivariate linear regression analyses were used to examine the effect of pSBP and cSBP on lnUACR, and further tests for interactions were performed according to associated covariates.@*Results@#Subjects were (59.0±8.6) years old, 36.2% (n=1 260) were male, 46.0% (n=1 595) had hypertension, and 20.2% (n=700) had diabetes. The pSBP and cSBP was (126.9 ± 16.4) mmHg (1 mmHg=0.133 kPa), and (136.3 ± 16.7) mmHg, respectively. P50 (P25-P75) of UACR was 6.2 (4.2-11.1) mg/g. Both pSBP and cSBP were linearly associated with lnUACR adjusted for age, sex, body mass index, smoking status, drinking status, triglyceride, HDL-C, LDL-C, fasting glucose, creatinine, history of cardiovascular disease, antihypertensive and hypoglycemic agents (every 10 mmHg increase for pSBP: β=0.12, 95%CI: 0.10-0.15, P<0.001; for cSBP: β=0.11, 95%CI: 0.09-0.14, P< 0.001). The relationships were remained in subgroups such as non-hypertension group, non-diabetes group, normal UACR group, and 3-combination group (every 10 mmHg increase for pSBP: β=0.09, 95%CI: 0.05-0.13; β=0.12, 95%CI: 0.10-0.15; β=0.07, 95%CI: 0.06-0.09; β=0.08, 95%CI: 0.05-0.12. for cSBP: β=0.07, 95%CI: 0.04-0.11; β=0.11, 95%CI: 0.08-0.13; β=0.07, 95%CI: 0.05-0.08; β=0.06, 95%CI: 0.03-0.09, all P<0.001). Furthermore, analyses for interaction found that both pSBP and cSBP were more strongly associated with lnUACR in males, current smokers and subjects with high serum creatinine level (≥87 µmol/L) when compared with females, non-current smokers and subjects with low serum creatinine level (<87 µmol/L), respectively (all P for interaction<0.05).@*Conclusion@#The results showed that both pSBP and cSBP were independently associated with UACR in this Chinese community-based population even in low risk population suggesting well-controlled both peripheral and central blood pressure may reduce urinary albumin. Males, current smokers and subjects with higher serum creatinine should pay more attention to the impacts of pSBP and cSBP on UACR.

ABSTRACT

<p><b>BACKGROUND</b>The primary cause of ischemic heart failure (HF) is myocardial infarction (MI) resulting in left ventricle (LV) wall motion abnormality secondary to ventricular remodeling. A prospective, nonrandomized study conducted in China was designed to assess safety and efficacy of the percutaneous ventricular restoration therapy using Parachute device (CardioKinetix, Inc., CA, USA) in ischemic HF patients as a result of LV remodeling after anterior wall MI.</p><p><b>METHODS</b>Thirty-one patients with New York Heart Association (NYHA) Class II, III ischemic HF, ejection fraction between 15% and 40%, and dilated akinetic or dyskinetic anterior-apical wall without the need to be revascularized were enrolled from seven sites in China from October to December 2014. The Parachute device was implanted through femoral artery. All patients received low-dose aspirin and anticoagulation with warfarin for at least 12 months postdevice implantation. The primary end-point was the assessment of efficacy as measured by the reduction in LV end-systolic volume index (LVESVI) against baseline LVESVI at 3 months postdevice implantation, determined by the echocardiography and measured by echocardiography core laboratory. Quality of life was assessed using EQ-5D and visual analog scale (VAS). For quantitative data comparison, paired t-test (normality data) and signed-rank test (abnormality data) were used; application of signed-rank test was for the ranked data comparison.</p><p><b>RESULTS</b>A change in LVESVI as measured by echocardiography from the preimplant baseline to 3-month postdevice implantation revealed a statistically significant reduction from 77.5 ± 20.0 ml/m2 to 53.1 ± 17.0 ml/m2 (P < 0.0001). The trial met its primary end-point. Of the 31 patients, the procedural success was 96.8%. Overall, NYHA HF class assessment results showed an improvement of more than half a class at 3 months (P < 0.001). Quality of life assessed by the VAS value increased 11.5 points (P < 0.01), demonstrating improvement at 3 months.</p><p><b>CONCLUSION</b>The favorable outcomes observed in the high-risk patients provide reassuring safety and efficacy data to support adoption of this technology as a therapeutic option for ischemic HF patients.</p><p><b>TRIAL REGISTRATION</b>ClinicalTrials.gov, NCT02240940; https://clinicaltrials.gov/ct2/show/NCT02240940.</p>

ABSTRACT

Objective: To analyze the current status of anticoagulant therapy for in-hospital patients with acute coronary syndromes (ACS) at county hospitals of China and to explore the relationship between anticoagulant therapy and clinical outcomes in real medical environment. Methods: 99 county hospitals from15 provinces of China were selected for this prospective registry study and 12373 eligible ACS patients without interventional therapy admitted from 2011-09 to 2014-06 were enrolled. The basic condition, previous history, initial assessment, anticoagulants (unfractionated heparin/low molecular weight heparin) application, severe bleeding events and in-hospital mortality were collected in all patients. Multiple logistic regression analysis was conducted to explore the relationship between anticoagulant therapy and clinical outcomes including in-hospital mortality, severe bleeding events and combined endpoints; meanwhile, possible confounders were adjusted. Results: A total of 9985/12373 ACS patients received anticoagulant therapy and 2388 did not. Anticoagulant therapy was conducted in 92.7% (4237/4570) patients with ST-segment elevation myocardial infarction (STEMI), 90.8% (1639/1805) with non-ST-segment elevation myocardial infarction (NSTEMI) and 68.5% (4109/5998) with unstable angina (UA); there were differences by regions and genders,P0.05. Meanwhile, it did not increase the risk of severe bleeding events in ACS patients,P>0.05. Conclusion: Anticoagulant therapy has been widely used in STEMI and NSTEMI patients at county hospitals of China and obviously decreased the in-hospital mortality; while the application rate was relatively low in UA patients. The general safety of anticoagulant therapy has been good in ACS patients.

ABSTRACT

Objective: To understand the gender disparity and influencing factors for in-hospital mortality in patients with ST-segment elevation myocardial infarction (STEMI) at secondary hospitals in China. Methods: A total of 5525 in-hospital STEMI patients from 99 secondary hospitals of 15 provinces or autonomous regions between 2011-09 to 2014-06 were recruited including 1649 female and 3876 male. The in-hospital mortalities were compared between 2 genders and the relevant inlfuencing factors were studied by multiple Logistic regression analysis. Results: There were about 29.8% female and 70.2% male STEMI patients were studied. The in-hospital mortalities in female and male were 13.2% and 5.9%,P<0.01; gender disparity was obviously existing regardless of age, history of MI, hypertension and diabetes mellitus. The mortality in female was higher than male even without diseases history and cardiovascular risk factors. Compared with male gender, female patients were usually having elder age and likely complicated with cardiovascular risk factors; they were with lower incidence to receive ECG, drug therapy and thrombolysis within 10 minutes of admission. With adjusted confounding factors, multiple regression analysis presented that female STEMI patients had the higher mortality than male (OR:1.7, 95% CI:1.4-2.0). Conclusion: The in-hospital mortality for STEMI patients was higher in female than male at secondary hospitals in China. Female patients were usually having elder age, complicated with more cardiovascular risk factors, while with less chances to receive ECG, drug therapy and thrombolysis within 10 minutes of admission.

ABSTRACT

Objective To investigate the differences in visceral fat area measured by bioelectrical impedance analysis in different sex and age groups, and explore the relationship between visceral fat area and other metabolic risk factors. Methods This study enrolled 72 in-patients in the department of cardiology in Peking University First Hospital between August, 2014 and October, 2014. The visceral fat area and the subcutaneous fat area were measured by DUALSCAN HDS-2000 in all patients. Results were compared between different sex and age groups and the relationship between visceral fat area and metabolic risk factors were analyzed. Resu1ts Male had larger visceral fat area than female [ ( 114. 04 ± 38. 27 ) cm2 vs. (92. 09 ±30. 57)cm2, P=0. 019], while female had larger subcutaneous fat areas than male [(223. 92 ± 73. 58)cm2 vs. (270. 35 ± 82. 13) cm2, P =0. 019] . Subcutaneous fat area and visceral fat area were positively correlated in both male ( r=0. 777, P﹤0. 001) and female ( r=0. 601, P=0. 002). There were no significant differences in visceral fat area among different age groups (P=0. 582). And visceral fat area had a positive correlation with body mass index (r=0. 748, P﹤0. 001), waist-hip ratio (r=0. 577, P﹤0. 001), abdominal circumference (r =0. 752, P ﹤0. 001) and HbA1c levels (r =0. 413, P =0. 001). Conc1usions There are sex differences in visceral fat area and subcutaneous fat area. The visceral fat area max be related to blood glucose levels and presence of diabetes.

ABSTRACT

<p><b>OBJECTIVE</b>To analyze the status of beta blockers (BBs) prescription in Chinese patients with stable angina pectoris. To determine the gap between clinical practice and treatment guidelines and factors influencing the use of BBs in Chinese patients.</p><p><b>METHOD</b>A questionnaire survey was conducted in patients diagnosed with chronic stable angina pectoris in 2011. A total of 298 Chinese hospitals attended the survey. The questionnaire collected patient demographic information, clinical and medication information. In the analysis, patients were divided into two groups according to whether they were on BBs at the time of the interview. Hospital characteristics, patient demographic information, cardiovascular risk factors, diagnostic method of coronary heart disease, past history of coronary revascularization and use of secondary prevention medications were compared between the two groups. Binary logistic regression analysis was used to identify factors related to BBs use. Patients were followed-up for 3 months. Patients who were on BBs at baseline were divided into two groups according to whether they were still on BBs after 3 months. Comparison of the clinical information previously mentioned was made between the two groups, and binary logistic regression analysis was used to identify factors related to BBs adherence.</p><p><b>RESULTS</b>Of the 5 011 questionnaires, 2 859 cases were male, mean age was (67.6 ± 11.5) years old, 3 060 (61.1%) patients were on BBs at baseline. Binary logistic regression analysis showed that when adjusted for other factors, old age (OR = 0.895, 95% CI 0.849-0.944, P<0.001) was related to no BBs use, while comorbidity with hypertension (OR = 1.255, 95% CI 1.103-1.427, P = 0.001) or hyperlipidemia (OR = 1.456, 95% CI 1.287-1.648, P<0.001), diagnosed with coronary disease by imaging (OR = 1.250, 95% CI 1.070-1.461, P = 0.005) and past history of coronary revascularization (OR = 1.490, 95% CI 1.220-1.820, P<0.001) were related to higher percentage of BBs use. A total of 2 533 cases (82.8%) were still taking BBs 3 months after baseline interview. Binary logistic regression analysis showed that, when adjusted for other factors, treated at traditional Chinese medical hospitals (OR = 1.612, 95% CI 1.154-2.251, P = 0.005), low levels of education (OR = 1.316, 95% CI 1.151-1.504, P<0.001), hypertension (OR = 1.345, 95% CI 1.096-1.651, P = 0.005), high baseline heart rate (OR = 1.020, 95% CI 1.010-1.030, P<0.001) and diagnosed with coronary disease by imaging (OR = 1.342, 95% CI 1.095-1.644, P = 0.005) were factors related to higher BBs adherence, while low baseline CCS class (OR = 0.794, 95% CI 0.704-0.896, P<0.001) was related to lower BBs adherence.</p><p><b>CONCLUSIONS</b>In Chinese patients with clinically diagnosed chronic stable angina, BBs use was not sufficient. Old age, comorbidity with hypertension or hyperlipidemia, past history of coronary revascularization were independently related to higher percentage of BBs use. Treated at traditional Chinese medical hospitals, low levels of education, hypertension, high baseline heart rate and diagnosed with coronary disease by imaging were independent factors related to higher BBs adherence, while low baseline CCS class was related to lower adherence.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the correlation between smoking status and carotid plaque in rural population residing in Eastern part of China.</p><p><b>METHODS</b>Between July and September of 2013, an epidemiological survey was carried out in residents aged 40 or above men who were enrolled randomly in rural areas of Anqing, Anhui province and Lianyungang, Jiangsu province. The data on epidemiological characteristics including smoking status, physical examination were collected using standardized protocol, and carotid ultrasonography was applied to examine the incidence of carotid plaque among never smokers, former smokers and current smokers. Logistic regress analysis was performed to determine the effect of smoking on carotid plaque.</p><p><b>RESULTS</b>In the study, a total of 625 male participants were included in the study. 51.4% (321 cases) were current smokers, 21.3% (133 cases) were former smokers, and 27.4% (171 cases) were never smokers. 32.0% (200/625) had carotid plaque. The incidence of carotid plaques was significantly higher in current smokers (35.2%, 113/321) than that in never smokers(23.4%,40/171) (χ(2) = 7.26, P = 0.007) and the incidence in former smokers (35.3%, 47/133) was also higher than that in never smokers (23.4%, 40/171) (χ(2) = 5.23, P = 0.022). Multiple logistic regression analysis showed that current cigarette smoking is significantly associated with the increased risk of carotid plaque (OR = 1.84, 95% CI: 1.13-2.98, P = 0.014) in comparison with never smokers, and there was an interaction between current smoking and age in association with carotid plaque. Compared with the young (≤60 years old) and never smoking group (8%, 3/40), prevalence of carotid plaque among the elderly (>70 years old) and smoking group (55%, 31/56) was significantly higher (OR = 8.06, 95% CI: 2.07-31.45) after adjusting for age, systolic blood pressure, diastolic blood pressure, blood glucose, total cholesterol, triglyceride high-density lipoprotein, body mass index, drinking and regional differences.</p><p><b>CONCLUSION</b>It found that cigarette smoking was associated with increased risk of carotid plaque in rural elderly population residing in Eastern part of China.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To compare the efficacy and safety of 5 mg perindopril arginine salt and 4 mg perindopril tert-butylamine salt for patients with mild to moderate essential hypertension.</p><p><b>METHODS</b>The study was designed as multicenter, randomized, double-blind, active controlled trial with two parallel groups enrolling 524 participants with mild to moderate essential hypertension. After 2-week run-in period, 186 patients were enrolled and randomly treated with 5 mg perindopril arginine salt and 183 patients were enrolled and randomly treated with 4 mg perindopril tert-butylamine salt. The random sequence was generated by the I.R.I.S., and a balance was made in each center. After double-blind treatment for 8 weeks, the dose could be doubled for patients with uncontrolled BP ((SBP) ≥ 140 mmHg (1 mmHg = 0.133 kPa) or diastolic blood pressure (DBP) ≥ 90 mmHg) and patients were treated for another 4 weeks.</p><p><b>RESULTS</b>The sitting SBP was similarly decreased by (19.9 ± 17.2) mmHg in perindopril arginine group and (18.5 ± 14.7) mmHg (P = 0.000 5) in perindopril tert-butylamine group post 8 weeks treatment. Dose was doubled in 109 patients (59.9%) in perindopril arginine group and 116 patients (63.7%) in perindopril tert-butylamine group. At 12 weeks post therapy, the sitting SBP decreased by (19.8 ± 16.2) and (19.6 ± 16.3) mmHg respectively in the 2 groups. The decrease of sitting DBP was also similar in both groups (-12.0 ± 10.0) mmHg and (-11.0 ± 8.9) mmHg (P < 0.000 1), respectively. The control rate or response rate was also similar between the two groups (control rate over 8 weeks was 38.5% vs. 31.3%, 95% CI (-2.6-16.9), control rate over 12 weeks was 36.3% vs. 35.7%, 95% CI (-9.3-10.4), response rate over 8 weeks was 64.3% vs. 63.2%, 95% CI (-8.8-11.0), response rate over 12 weeks was 65.9% vs. 64.8%, 95% CI (-8.7-10.9)). Incidence of adverse events was low and similar in both therapy groups.</p><p><b>CONCLUSIONS</b>The results show that perindopril arginine salt 5 mg is as efficient as perindopril tert-butylamine 4 mg on lowering BP for patients with mild to moderate essential hypertension. Both drugs have good safety profile and are well tolerated by patients in this cohort.</p>

ABSTRACT

In 21th century, percutaneous coronary intervention (PCI) technique enters in rapid development stage in China. From 2009, quality control system of PCI runs in national scale. Since then, the national quality control center estab?lished cooperative relationship with the provincial quality control centers. Official website and quality control tools were im?proved. PCI data were collected and analyzed annually, and then reported to the regulatory body and published to the public. Audit was run irregularly. Quality control centers were also involved in some other related affairs such as training course and admission. The quality control system lead PCI in China to an improved daily practice and control PCI application all overthe country in terms of data. In the future, the quality control techniques and teamwork will be further improved. And quality evaluation system and management team will be perfected gradually. Quality control will be extended from PCI to coronary heart disease and combined with audit of coronary heart disease. According to the quality control data, the quality and its rank of medical centers will be published in certain range. So that we can provide better care to the coronary heart disease pa?tients.

ABSTRACT

Objective To investigate the correlation between the levels of placenta growth factor (PLGF),soluble angiopoietin receptor-2 (sTie-2) and critical coronary artery plaque imaging morphology of coronary borderline lesions in patients with coronary heart disease (CHD).Methods In three consecutive years from April 2007 to September 2009,a cohort of 719 patients with borderline coronary lesions with stenosis in three main vessels with lumen diameter reduction varied all the way from more than 20% to less than 70% and with greater than 2.25 mm of the inner diameter were selected in this study from 4 teaching hospitals of tertiary class A in Beijing.These patients fell into three categories:unstable angina pectoris (UAP,n =292),stable angina pectoris (SAP,n =219) and coronary arteriosclerosis (AS,n =208).The vessels involved were analyzed using quantitative coronary angiography (QCA).Plasma levels of PLGF and sTie-2 were measured by using protein chip.The relationship between plasma levels of vascular factors,sTie-2,PLGF and coronary artery plaque imaging morphology among three groups were analyzed.Results (1) Plasma level of PLGF was 80.33 ng/L in the UAP group,which was significantly higher than 54.29 ng/L in the SAP group and 45.16 ng/L in AS group (both P <0.05).Plasma level of sTie-2 was 1353.06 ng/L in the UAP group,which was significantly higher than 1308.28 ng/L in the AS group (P =0.008).(2) There was significantly statistical differences in QCA between the SAP group and the UAP group as well as the AS group (both P < 0.05) in terms of the minimal lumen diameter,diameter stenosis rate,minimal lumen cross-sectional area and cross-sectional area of stenosis.The plaque area in the UAP group was larger than that in the AS group (P =0.013).(3) The relationship between vascular factors and plaque imaging morphology was analyzed.There was significantly statistical difference in the involved lesions among the three groups (P < 0.01).(4) There was a positive correlation between plasma level of PLGF and minimal lumen cross-sectional area (r =0.493,P =0.009).Conclusions The plasma levels of PLGF and sTie-2 reflect the level of neo-vascularization in the plaque,and could be taken as predictive factors for potential pathogenesis of coronary plaque.

ABSTRACT

<p><b>OBJECTIVE</b>To analyze the relationship between normal high blood pressure and carotid artery atherosclerosis.</p><p><b>METHODS</b>This epidemiological survey was performed in two communities of Shijingshan District of Beijing from 2007 to 2008. A total of 3 324 people were enrolled in the study and 2 895 people with carotid ultrasound survey results were analyzed. Blood lipids, blood pressure, hs-CRP, body mass index (BMI) and other cardiovascular risk factors were obtained. Carotid mean intima-media thickness (IMT) , maximum carotid IMT and carotid plaque were measured by ultrasound. A multiple logistic regression model was used to evaluate the relationship between normal high blood pressure and carotid artery atherosclerosis.</p><p><b>RESULTS</b>The carotid mean IMT, maximum IMT, incidence of carotid artery plaque increased in proportion to blood pressure level (all P < 0.01) . After adjusting for diabetes, hypercholesterolemia, hypertriglyceridemia, increased hs-CRP, smoking, sex, age, overweight and obesity, multiple logistic regression analysis showed that the OR values of carotid mean IMT and maximum IMT thickening, carotid plaque in high normal blood pressure group were 4.50 (95% CI: 1.04-19.49, P < 0.05), 1.73 (95% CI: 1.35-2.22, P < 0.01), 1.64 (95% CI:1.26-2.13, P < 0.01) compared to normal blood pressure group.</p><p><b>CONCLUSION</b>High normal blood pressure is related with higher risk of carotid artery atherosclerosis in this cohort.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To study the changes of adenosine diphosphate (ADP)-induced platelet aggregation rate, and evaluate the effects of Maixuekang Capsule (, MKC) on platelet aggregation rate and long-term prognosis of patients with acute coronary syndrome after percutaneous coronary intervention (PCI).</p><p><b>METHODS</b>A total of 236 patients with acute coronary syndrome, who received successful PCI, were randomly assigned to a trial group (116 cases) and a control group (120 cases) according to random numbers; treatment allocation occurred when the participants met the inclusion criteria and signed the informed consent forms. In the trial group, the patients were treated with MKC combined with routine medication, and in the control group the patients were treated with routine medication. The therapeutic course for the two groups was 12 months and the follow-up was 12 months. The levels of ADP-induced platelet aggregation rate and serum high-sensitive C-reactive protein (hs-CRP) were determined before PCI, 12 h and 30 days after PCI. In the meantime, the incidence of cardio-/cerebrovascular events was recorded during the 12-month follow-up.</p><p><b>RESULTS</b>Compared with before PCI, the levels of ADP-induced platelet aggregation rate and serum hs-CRP were significantly higher at 12 h after PCI (P<0.05). They were significantly reduced after 30-day-treatment of MKC, showing statistical differences when compared with those in the control group (P<0.05). During the 12-month follow-up, the incidence of cardio-/cerebrovascular events was significantly lower in the trial group than in the control group (6.9% vs. 12.5%, P<0.01).</p><p><b>CONCLUSIONS</b>ADP-induced platelet aggregation function was significantly elevated after PCI. MKC improved the prognosis of patients with acute coronary syndrome, possibly through inhibiting the platelet aggregation, fighting against inflammation, and protecting the vascular endothelial function.</p>
