ABSTRACT
OBJECTIVE@#To analyze the factors related to pregnancy of endometriosis and whether Chinese herbal medicines (CHMs) can improve pregnancy outcomes in patients with endometriosis in long-term management.@*METHODS@#This multicenter cohort study retrospectively analyzed the clinical data of endometriosis patients with fertility needs from January 2019 to November 2019. A total of 252 patients with endometriosis from 5 level-III Grade A hospitals in Beijing were included in this study. Univariate and multivariate logistic regression analysis were performed for the relevant factors. The propensity score matching (PSM) function of SPSS software was used to match the CHMs group with the non-CHMs group. The pregnancy rate and live birth rate were analyzed.@*RESULTS@#The results of univariate analysis showed that age, disease course, presence of infertility, presence of adenomyosis, time after surgery or use of gonadotropin-releasing hormone agonist (GnRH-a), use of CHMs and follow-up time were influencing factors of pregnancy in endometriosis patients (P<0.05). The results of multivariate analysis showed that age, presence of adenomyosis, time after surgery or use of GnRH-a, use of CHMs and follow-up time were independent factors affecting pregnancy in endometriosis patients, among which, age ⩾35 years old, presence of adenomyosis and follow-up time >6 months were independent risk factors (OR=0.445, 0.348, 0.140, respectively, P<0.05), time after surgery or use of GnRH-a ⩽6 months and use of CHMs were independent protective factors (OR=3.839, 3.842, respectively, P<0.05). After PSM, 99 pairs of two groups were matched successfully. The pregnancy rate of the CHMs group was higher than that of the non-CHMs group [55.56% (55/99) vs. 36.36% (36/99), P<0.05]. The live birth rate of the CHMs group was higher than that of the non-CHMs group [49.49% (49/99) vs. 35.35% (35/99), P<0.05].@*CONCLUSION@#CHMs can effectively improve clinical pregnancy rate and live birth rate of patients with endometriosis in the chronic disease management.

Objective: To investigate the functional changes of key gut microbiota (GM) that produce lipopolysaccharide (LPS) in atrial fibrillation (AF) patients and to explore their potential role in the pathogenesis of AF. Methods: This was a prospective cross-sectional study. Patients with AF admitted to Beijing Chaoyang Hospital of Capital Medical University were enrolled from March 2016 to December 2018. Subjects with matched genetic backgrounds undergoing physical examination during the same period were selected as controls. Clinical baseline data and fecal samples were collected. Bacterial DNA was extracted and metagenomic sequencing was performed by using Illumina Novaseq. Based on metagenomic data, the relative abundances of KEGG Orthology (KO), enzymatic genes and species that harbored enzymatic genes were acquired. The key features were selected via the least absolute shrinkage and selection operator (LASSO) analysis. The role of GM-derived LPS biosynthetic feature in the development of AF was assessed by receiver operating characteristic (ROC) curve, partial least squares structural equation modeling (PLS-SEM) and logistic regression analysis. Results: Fifty nonvalvular AF patients (mean age: 66.0 (57.0, 71.3), 32 males(64%)) were enrolled as AF group. Fifty individuals (mean age 55.0 (50.5, 57.5), 41 males(82%)) were recruited as controls. Compared with the controls, AF patients showed a marked difference in the GM genes underlying LPS-biosynthesis, including 20 potential LPS-synthesis KO, 7 LPS-biosynthesis enzymatic genes and 89 species that were assigned as taxa harbored nine LPS-enzymatic genes. LASSO regression analysis showed that 5 KO, 3 enzymatic genes and 9 species could be selected to construct the KO, enzyme and species scoring system. Genes enriched in AF group included 2 KO (K02851 and K00972), 3 enzymatic genes (LpxH, LpxC and LpxK) and 7 species (Intestinibacter bartlettii、Ruminococcus sp. JC304、Coprococcus catus、uncultured Eubacterium sp.、Eubacterium sp. CAG:251、Anaerostipes hadrus、Dorea longicatena). ROC curve analysis revealed the predictive capacity of differential GM-derived LPS signatures to distinguish AF patients in terms of above KO, enzymatic and species scores: area under curve (AUC)=0.957, 95%CI: 0.918-0.995, AUC=0.940, 95%CI 0.889-0.991, AUC=0.972, 95%CI 0.948-0.997. PLS-SEM showed that changes in lipopolysaccharide-producing bacteria could be involved in the pathogenesis of AF. The key KO mediated 35.17% of the total effect of key bacteria on AF. After incorporating the clinical factors of AF, the KO score was positively associated with the significantly increased risk of AF (OR<0.001, 95%CI:<0.001-0.021, P<0.001). Conclusion: Microbes involved in LPS synthesis are enriched in the gut of AF patients, accompanied with up-regulated LPS synthesis function by encoding the LPS-enzymatic biosynthesis gene.

ObjectiveNeNewly onset atrial fibrillation (AF) is a common complication of acute myocardial infarction (AMI), which is considered to be related to cardiovascular adverse events. This paper aims to discuss the relationship between atrial fibrillation and long-term cardiovascular adverse events after acute myocardial infarction.MethodsA retrospective analysis of 483 STEMI patients with multivessel disease, who underwent emergency percutaneous coronary intervention (PCI) in Beijing Chaoyang Hospital from January 2014 to May 2017, was conducted. Patients were divided into two groups: AF group: n=52(10.8%) and non-AF group: n=431(89.2%) according to including criteria. The primary endpoint event was long-term major adverse cardiovascular events, including cardiovascular death, acute heart failure or ischemia stroke. The secondary endpoint event was defined as 30-day cardiovascular death. Multivariate logistic regression analysis and Cox proportional hazards mode were performed to analyze the relationship between newly onset atrial fibrillation and cardiovascular adverse events, such as cardiovascular death. ResultsCompared with non-AF group, AF group had older age, higher levels of C-reactive protein, erythrocyte sedimentation rate, creatinine, troponin, SYNTAX score and GRACE score and lower levels of total cholesterol, low density lipoproteins and ejection fraction (P<0.01). In the multivariate logistic regression analysis model, newly onset atrial fibrillation, age, high-sensitivity C-reactive protein, erythrocyte sedimentation rate, admission creatinine level, fasting blood glucose, and coronary SYNTAX score were all independent risk factors associated with higher risks of 30-day cardiovascular death (OR=1.983, 95% CI=1.036-3.795, P=0.04). Using Cox proportional hazards mode, newly onset atrial fibrillation following primary PCI was associated with long-term clinical adverse cardiovascular event (HR=1.983, 95% CI=1.036-3.795, P=0.04) after adjusting all covariates. The area under the ROC curve for combined prediction mode with GRACE score and newly onset AF was comparable to the one for the model with GRACE score alone (0.788 vs 0.767,P=0.08).ConclusionNewly onset atrial fibrillation in STEMI patients with multivessel disease who underwent emergency PCI is associated with 30-day cardiovascular death and long-term clinical adverse cardiovascular events. However, newly onset atrial fibrillation does not increase the predictive value of GRACE score.
ABSTRACT
BACKGROUND@#Recent studies have reported circular RNA (circRNA) expression profiles in various tissue types; however, circRNA expression profile in human epicardial adipose tissue (EAT) remains undefined. This work aimed to compare circRNA expression patterns in EAT between the heart failure (HF) and non-HF groups.@*METHODS@#RNA-sequencing was carried out to compare circRNA expression patterns in EAT specimens from coronary artery disease cases between the HF and non-HF groups. Quantitative real-time polymerase chain reaction was performed for validation. Comparisons of patient characteristics between the two groups were using t test, Mann-Whitney U test, and Chi-squared test.@*RESULTS@#A total of 141 circRNAs substantially different between the HF and non-HF groups (P 2) were detected, including 56 up-regulated and 85 down-regulated. Among them, hsa_circ_0005565 stood out, for it had the highest fold change and was significantly increased in HF patients in quantitative real-time polymerase chain reaction validation. The top highly expressed EAT circRNAs corresponded to genes involved in cell proliferation and inflammatory response, including GSE1, RHOBTB3, HIPK3, UBXN7, PCMTD1, N4BP2L2, CFLAR, EPB41L2, FCHO2, FNDC3B, and SPECC1. The top enriched Gene Ontology term and Kyoto Encyclopedia of Genes and Genomes pathway were positive regulation of metabolic processes and insulin resistance, respectively.@*CONCLUSION@#These data indicate EAT circRNAs may contribute to the pathogenesis of metabolic disorders causing HF.

BACKGROUND@#The Chinese appropriate use criteria (AUC) for coronary revascularization was released in 2016 to improve the use of coronary revascularization. This study aimed to evaluate the association between the appropriateness of coronary revascularization based on the Chinese AUC and 1-year outcomes in stable coronary artery disease (CAD) patients.@*METHODS@#We conducted a prospective, multi-center cohort study of stable CAD patients with coronary lesion stenosis ≥50%. After the classification of appropriateness based on Chinese AUC, patients were categorized into the coronary revascularization group or the medical therapy group based on treatment received. The primary outcome was a composite of death, myocardial infarction, stroke, repeated revascularization, and ischemic symptoms with hospital admission.@*RESULTS@#From August 2016 to August 2017, 6085 patients were consecutively enrolled. Coronary revascularization was associated with a lower adjusted hazard of 1-year major adverse cardiovascular and cerebrovascular events (MACCEs; hazard ratio [HR]: 0.62; 95% confidence interval [CI]: 0.45-0.86; P = 0.004) than medical therapy in patients with appropriate indications (n = 1617). No significant benefit in 1-year MACCEs was found after revascularization compared to after medical therapy in patients with uncertain indications (n = 2658, HR: 0.81; 95% CI: 0.52-1.25; P = 0.338) and inappropriate indications (n = 1810, HR: 0.80; 95% CI: 0.51-1.23; P = 0.308).@*CONCLUSIONS@#In patients with appropriate indications according to Chinese AUC, coronary revascularization was associated with significantly lower risk of MACCEs at 1 year. No benefit was found in coronary revascularization in patients with inappropriate indications. Our findings provide evidence for using Chinese AUC to guide clinical decision-making.@*CLINICAL TRIAL REGISTRATION@#NCT02880605. https://www.clinicaltrials.gov.
ABSTRACT
BACKGROUND@#Resting heart rate (RHR) is considered as a strong predictor of total mortality and hospitalization due to heart failure in hypertension patients. Bisoprolol fumarate, a second-generation beta-adrenoreceptor blockers (β-blocker) is commonly prescribed drug to manage hypertension. The present study was to retrospectively evaluate changes in the average RHR and its association with cardiovascular outcomes in bisoprolol-treated coronary artery disease (CAD) patients from the CAD treated with bisoprolol (BISO-CAD) study who had comorbid hypertension.@*METHODS@#We performed ad-hoc analysis for hypertension sub-group of the BISO-CAD study (n = 866), which was a phase IV, multination, multi-center, single-arm, observational study carried out from October 2011 to July 2015 across China, South Korea, and Vietnam. Multivariate regression analysis was used to identify factors associated with incidence of composite cardiac clinical outcome (CCCO), the results were presented as adjusted odds ratio (OR) along with 95% confidence interval (CI) and adjusted P value.@*RESULTS@#A total of 681 patients (mean age: 64.77 ± 10.33 years) with hypertension from BISO-CAD study were included in the analysis. Bisoprolol improved CCCOs in CAD patients with comorbid hypertension, with RHR <65 and <70 beats/min compared with RHR ≥65 and ≥75 beats/min, respectively, in the efficacy analysis (EA) set. In addition, it lowered RHR in both intent-to-treat (ITT) and EA groups after 6, 12, and 18 months of treatment. Further, RHR 70 to 74 beats/min resulted in significantly higher risk of CCCOs EA set of patients (adjusted OR: 4.34; 95% CI: 1.19-15.89; P = 0.03). Also, events of hospitalization due to acute coronary syndrome were higher when RHR 69 to 74 beats/min compared to RHR <69 beats/min in ITT patients.@*CONCLUSION@#Bisoprolol can effectively reduce RHR in Asian CAD patients with comorbid hypertension and hence, improve CCCO without affecting their blood pressure.
ABSTRACT
Objective: To compare the safety profile, angiographic and clinical outcomes between drug-coated balloon(DCB) only strategy versus drug eluting stent(DES) implantation in primary percutaneous coronary intervention(PCI) for acute myocardial infarction(AMI) patients. Methods: A total of 380 AMI patients who underwent primary PCI in Beijing Chaoyang Hospital from January 2016 to May 2019 were enrolled. They were allocated into DEB group(n=180) or DES group(n=200). The Primary endpoint was the major adverse cardiac events(MACE) in hospital and within 3 months after discharge, the composite event of cardiac death, non-fatal myocardial infarction(MI), target vessel revascularization(TVR) and in stent thrombosis. The secondary endpoints included: (1)TIMI blood flow grade and myocardial perfusion grade (TMP grade) of infarct-related vessels before and after PCI. (2)The degree of ST segment resolution(STR) between half hour and two hours after PCI, and STR was represented by percentage of summed ST-segment reduction between baseline and post-PCI. Using the most significant lead of ST segment elevation, calculating the rate of decline in the ST segment after treatment; or the most significant lead of the ST segment depression, to calculate the rate of recovery in the ST segment after treatment. STR<50% was defined as incomplete STR. (3)The occurrence of coronary artery dissection during operation. (4)The peak value of myocardial enzymes. (5)The incidence of bleeding in hospital and within 3 months after discharge. The inverse probability weighting method based on propensity score (IPTW) was used to compare the effects of the two treatments on MACE occurrence in the logistic regression model. Results: There was no significant difference in sex, age, risk factors of coronary heart disease, type and site of AMI, interventional therapy data(P>0.05) between the two groups. The ratio of bifurcation lesions in DCB group was significantly higher than that in DES group, and the diameter of the DCB was smaller while the length was longer than that of DES (all P<0.05). One death occurred in each group during hospitalization. Compared with the DES group, the incidence of MI [2.8%(5/180) vs. 0.5% (1/200), P=0.10] and TVR [2.8%(5/180) vs. 0.5%(1/200), P=0.10] in the DCB group during hospitalization showed an increasing trend, and were mostly associated with delayed coronary dissection. The incidence of MACE was similar between the two groups (3.3%(6/180) and 1.0%(2/200), P=0.15) during hospitalization. There was no MACE occurred in the two groups within 3 months after discharge. There was no significant difference between the two groups in TIMI grade, TMP grade, incomplete STR rate and peak value of myocardial enzyme (all P>0.05). The incidence of coronary artery dissection was significantly higher in DCB group than in DES group (8.3%(15/180) and 3.0%(6/200), P=0.02), but most of them were type B or A dissection and did not need special treatment. There was no significant difference in bleeding event between the two groups(P=0.91). Logistic regression analysis showed that there was no difference in the risk of MACE during hospitalization between DES and DCB groups for AMI patients receiving PCI (compared with DCB, OR=0.35, 95%CI 0.08-1.43, P=0.13). Conclusions: The initial safety and efficacy profiles of DCB are similar with those of DES for the AMI patients during PCI. The study highlights that the incidence of coronary dissection (type A or B) is higher post DCB treatment than post DES, but it does not affect blood flow. However, the incidence of in-hospital MI due to delayed coronary dissection trends to be higher post DCB. So we should pay close attention to the risk of delayed coronary dissection after DCB in AMI patients with de novo lesion.

Objective: To analyze the prognostic value of baseline serum free light chain (sFLC) in immunoglobulin light-chain cardiac amyloidosis (AL-CA) . Methods: Thirty patients diagnosed with AL-CA from January 2012 to December 2016 at Beijing Chaoyang Hospital were included in this study to retrospectively evaluate the clinical data. The cut-off value of dFLC (involved sFLC minus uninvolved sFLC) was determined according to the receiver operator characteristic curve (ROC) and grouped, the prognoses of both groups were evaluated. Results: The onset age of all AL-CA patients was 57 years old. It occurred more commonly in men (21 cases, 70%) and the light chains of immunoglobulin composed mainly of type λ (22 cases, 73.3%) . Renal involvements occurred in 17 cases (56.7%) . The median value of difference between involved and uninvolved serum immunoglobulin free light chain levels (dFLC) was 162.9 (57.9-401.6) mg/L. More subjects in the high dFLC group had higher BNP (P=0.005) , and shorter median survival than those in the low dFLC group (15 months vs 47 months, P<0.001) . Similar results of median survival were observed when the patients were redivided by a new cut-off value of 180 mg/L for dFLC (high dFLC group: 22 months, low dFLC group: 40 months, P=0.001) , or a κ/λ ratio in which patients with κ type sFLC-ratio<3.79 and λ type sFLC-ratio≥0.06 were grouped into the low sFLC-ratio (37 months) , and the reverse the high sFLC-ratio ones (25 months, P=0.021) . In multivariate analysis, dFLC and New York Heart Association (NYHA) classification of cardiac function were two risk factors associated with all-cause mortality in patients, of them the hazard ratio for higher dFLC was 12.13 (95%CI 2.98-49.30, P<0.001) . Conclusion: Measurement of the sFLC level could implicate the prognosis of AL-CA.

BACKGROUND@#Cardiac rupture (CR) is a major lethal complication of acute myocardial infarction (AMI). However, no valid risk score model was found to predict CR after AMI in previous researches. This study aimed to establish a simple model to assess risk of CR after AMI, which could be easily used in a clinical environment.@*METHODS@#This was a retrospective case-control study that included 53 consecutive patients with CR after AMI during a period from January 1, 2010 to December 31, 2017. The controls included 524 patients who were selected randomly from 7932 AMI patients without CR at a 1:10 ratio. Risk factors for CR were identified using univariate analysis and multivariate logistic regression. Risk score model was developed based on multiple regression coefficients. Performance of risk model was evaluated using receiver-operating characteristic (ROC) curves and internal validity was explored using bootstrap analysis.@*RESULTS@#Among all 7985 AMI patients, 53 (0.67%) had CR (free wall rupture, n = 39; ventricular septal rupture, n = 14). Hospital mortalities were 92.5% and 4.01% in patients with and without CR (P < 0.001). Independent variables associated with CR included: older age, female gender, higher heart rate at admission, body mass index (BMI) <25 kg/m, lower left ventricular ejection fraction (LVEF) and no primary percutaneous coronary intervention (pPCI) treatment. In ROC analysis, our CR risk assess model demonstrated a very good discriminate power (area under the curve [AUC] = 0.895, 95% confidence interval: 0.845-0.944, optimism-corrected AUC = 0.821, P < 0.001).@*CONCLUSION@#This study developed a novel risk score model to help predict CR after AMI, which had high accuracy and was very simple to use.

BACKGROUND@#Depression and anxiety have been correlated with elevated risks for quality-of-life (QOL), adverse outcomes, and medical expenditure in patients with acute coronary syndrome (ACS). However, the relevant data are lacking for Chinese ACS populations, especially regarding different effects of major depression, anxiety, and comorbidity. The objective of this study was to evaluate the dynamic changes of depression and/or anxiety over 12 months and examine the effects of depression, anxiety, and comorbidity on QOL, adverse outcomes, and medical expenditure in Chinese patients with ACS.@*METHODS@#For this prospective longitudinal study, a total of 647 patients with ACS were recruited from North China between January 2013 and June 2015. Among them, 531 patients (82.1%) completed 12-month follow-ups. Logistic regression model was utilized for analyzing the association of baseline major depression, anxiety, and comorbidity with 12-month all-cause mortality, cardiovascular events, QOL, and health expenditure.@*RESULTS@#During a follow-up period of 12 months, 7.3% experienced non-fatal myocardial infarction (MI) and 35.8% cardiac re-hospitalization. Baseline comorbidity, rather than major depression/anxiety, strongly predicted poor 12-month QOL as measured by short-form health survey-12 (odds ratio [OR]: 1.77, 95% confidence interval [CI]: 1.22-2.52, P = 0.003). Regarding 12-month non-fatal MI and cardiac re-hospitalization, baseline anxiety (OR: 2.83, 95% CI: 1.33-5.89, P < 0.01; OR: 4.47, 95% CI: 1.50-13.00, P < 0.01), major depression (OR: 2.58, 95% CI: 1.02-6.15, P < 0.05; OR: 5.22, 95% CI: 1.42-17.57, P < 0.03), and comorbidity (OR: 6.33, 95% CI: 2.96-13.79, P < 0.0001, OR: 14.08, 95% CI: 4.99-41.66, P < 0.0001) were all independent predictors, and comorbidity had the highest predictive value. Number of re-hospitalization stay, admission frequency within 12 months and medical expenditure within 2 months were the highest in patients with ACS with comorbidity.@*CONCLUSIONS@#Major depression and anxiety may predict 12-month non-fatal MI and cardiac re-hospitalization. However, comorbidity has the highest predictive value with greater medical expenditure and worse QOL in Chinese patients with ACS. And depression with comorbid anxiety may be a new target of mood status in patients with ACS.

ABSTRACT
<p><b>INTRODUCTION</b>Acute myocardial infarction (AMI) due to unprotected left main coronary artery (ULMCA) disease is clinically catastrophic although it has a low incidence. Studies on the long-term prognosis of these patients are rare.</p><p><b>METHODS</b>From January 1999 to September 2013, 55 patients whose infarct-related artery was the ULMCA were enrolled. Clinical, angiographic and interventional data was collected. Short-term and long-term clinical follow-up results as well as prognostic determinants during hospitalisation and follow-up were analysed.</p><p><b>RESULTS</b>Cardiogenic shock (CS) occurred in 30 (54.5%) patients. During hospitalisation, 22 (40.0%) patients died. Multivariate logistic regression analysis showed that CS (odds ratio [OR] 5.86; p = 0.03), collateral circulation of Grade 2 or 3 (OR 0.14; p = 0.02) and final flow of thrombolysis in myocardial infarction (TIMI) Grade 3 (OR 0.05; p = 0.03) correlated with death during hospitalisation. 33 patients survived to discharge; another seven patients died during the follow-up period of 44.6 ± 31.3 (median 60, range 0.67-117.00) months. The overall mortality rate was 52.7% (n = 29). Kaplan-Meier analysis showed that the total cumulative survival rate was 30.7%. Cox multivariate regression analysis showed that CS during hospitalisation was the only predictor of overall mortality (hazard ratio 4.07, 95% confidence interval 1.40-11.83; p = 0.01).</p><p><b>CONCLUSION</b>AMI caused by ULMCA lesions is complicated by high incidence of CS and mortality. CS, poor collateral blood flow and failure to restore final flow of TIMI Grade 3 correlated with death during hospitalisation. CS is the only predictor of long-term overall mortality.</p>

<p><b>BACKGROUND</b>Cardiovascular disease (CVD) is the leading cause of death in patients with end-stage renal disease (ESRD). We explored the relationship between CVD, plasma brain natriuretic peptide (BNP) and copeptin in non-dialysis patients with chronic kidney disease (CKD).</p><p><b>METHODS</b>BNP and copeptin were measured using ELISA in 86 non-dialysis patients with different degrees of CKD and in 20 control patients. The effects of BNP, copeptin levels and other biochemical indices on carotid ultrasound echocardiography and CVD history were determined using correlation analysis.</p><p><b>RESULTS</b>BNP and copeptin levels were significantly higher in the CKD group than in the control group. Both indices increased progressively, in parallel with the decline in glomerular filtration rate (GFR). BNP levels were (184.25 ± 65.18) ng/L in early phase CKD, (975.245 ± 354.09) ng/L in middle phase CKD, and (1463.51 ± 614.92) ng/ml in end phase CKD compared with levels of (101.56 ± 42.76) ng/L in the control group (all P < 0.01). Copeptin levels in the middle phase ((20.36 ± 9.47) pmol/L) and end phase groups ((54.26 ± 18.23) pmol/L were significantly higher than in the control group ((9.21 ± 2.64) pmol/L; both P < 0.01). There was no difference in copeptin levels between early phase CKD ((10.09 ± 5.23) pmol/L) and control patients. Stepwise multiple regression analysis identified GFR, intima-media thickness (IMT), left ventricular hypertrophy (LVH), and previous history of CVD as independent risk factors for elevated BNP and copeptin levels.</p><p><b>CONCLUSION</b>BNP and copeptin appear to provide sensitive biological markers for the evaluation of atherosclerosis in non-dialysis patients with CKD.</p>

<p><b>OBJECTIVE</b>To investigate the low-density lipoprotein cholesterol (LDL-C) levels in outpatients with coronary heart disease (CHD) visiting cardiology outpatient clinics of 8 hospitals in Beijing.</p><p><b>METHODS</b>A total of 903 outpatients with CHD were enrolled from 4 three-tier hospitals and 4 two-tier hospitals in Beijing. All patients were asked to finish the questionnaire including demographic data, CHD history, the knowledge on cholesterol, and the use of statins. Blood lipid was examined and the LDL-C control rate and related factors were then analyzed.</p><p><b>RESULTS</b>Questionnaire was obtained from 876 patients [619 male: 70.7%, mean age: (64.9 ± 10.7) years old] and blood lipid data were available in 709 patients. The general LDL-C control rate was 36.9% (262/709) and was 13.5% (27/173) in very high risk CHD patients, and lower in patients treated in two-tier hospitals than patients treated in three-tier hospitals[31.3% (121/386) vs. 43.7% (141/323), P < 0.01], in female patients than in male patients [27.1% (60/261) vs. 41.3% (201/496), P < 0.01] and in diabetic patients than in non-diabetic patients [13.5% (27/200) vs. 44.7% (197/441), P < 0.01]. The LDL-C control rate was lower in patients less than 60 years old and patients over 80 years old than that in 60-70 years old patients and 70 - 80 years old patients (P < 0.05). LDL-C control rate was not affected by the history of hypertension, percutaneous coronary intervention or coronary artery bypass grafting, smoking, lipid examination frequency, knowledge on goal level of LDL-C, diet control and regularly physical exercising (all P > 0.05). There were 18.2% (129/709) patients not taking statins or not aware if they were taking statin or not. The main reason for not taking statin [47.9% (23/48)] was statin was no prescribed by doctors, followed by withdrawal by patients due to various reasons [27.1% (13/48)].</p><p><b>CONCLUSIONS</b>LDL-C control rate was low in patients with CHD visiting cardiology outpatient clinics in Beijing. The CHD patients and cardiologists should be encouraged to achieve better LDL-C control by following lipid lowering guidelines and it is also important to improve the drug compliance among CHD patients.</p>

<p><b>OBJECTIVE</b>To analyze the cause of in-hospital death among acute myocardial infarction patients undergoing primary percutaneous coronary intervention (PPCI) in Beijing area to evoke better individualized preventive approach.</p><p><b>METHODS</b>In-hospital mortality and causes were analyzed based on database from Beijing percutaneous coronary intervention registry study (BJPCI Registry) in 2010.</p><p><b>RESULTS</b>A total of 4660 PPCI patients from 48 hospitals were included. In-hospital mortality was 2.4% (n = 110). Cardiogenic shock (39.1%, 43/110), mechanical complications (28.2%, 31/110) and intervention-related complications [28.2%, 31/110: procedure related (n = 28), drug related (n = 3)] were the leading causes of in-hospital death. Five deaths was attributed to comorbidity related reason (4.5%, 5/110). The in-hospital mortality had no significant difference among hospitals of different grade or total annual PCI (all P > 0.05). In-hospital mortality was slightly higher in hospital with annual PPCI < 300 than in hospitals with annual PPCI ≥ 300 (2.9% vs. 1.8%, P < 0.05).</p><p><b>CONCLUSION</b>Cardiogenic shock, mechanical complications and intervention-related complications are the main causes of in-hospital death among acute myocardial infarction patients receiving PPCI.</p>

<p><b>OBJECTIVE</b>We identify ionizing radiation-induced mitochondrial DNA (mtDNA) deletions in human lymphocytes and their distribution in normal populations.</p><p><b>METHODS</b>Long-range polymerase chain reactions (PCR) using two pairs of primers specific for the human mitochondrial genome were used to analyze the lymphoblastoid cell line following exposure to 10 Gy (60)Co γ-rays. Limited-condition PCR, cloning and sequencing techniques were applied to verify the mtDNA deletions detected with long-range PCR. Human peripheral blood samples were irradiated with 0, 2 and 6 Gy (60)Co γ-rays, and real-time PCR analysis was performed to validate the mtDNA deletions. In order to know the distribution of mtDNA deletions in normal population, 222 healthy Chinese adults were also investigated.</p><p><b>RESULTS</b>Two mtDNA deletions, a 7455-bp deletion (nt475-nt7929 in heavy strand) and a 9225-bp deletion (nt7714 -nt369 in heavy strand), occurring between two 8-bp direct repeats, were identified in lymphoblastoid cells using long-range PCR, limited-condition PCR and sequencing. These results were also observed for (60)Co γ-rays irradiated human peripheral blood cells.</p><p><b>CONCLUSION</b>Two novel mtDNA deletions, a 7455-bp deletion and a 9225-bp deletion, were induced by ionizing radiation. The rate of the mtDNA deletions within a normal population was related to the donors' age, but was independent of gender.</p>

<p><b>OBJECTIVE</b>To explore the clinical effect of primary percutaneous coronary intervention (PCI) in patients with acute myocardial infarction (AMI) induced by left main artery total or subtotal occlusion.</p><p><b>METHODS</b>Between January 1995 and June 2010, there were 28 AMI patients [24 males, mean age (61.5 ± 2.3) years, 15 patients complicated with cardiac shock] with left main occlusion or severe stenosis who were treated with PCI in our center. The clinical features were compared between death group and survival group. All survival cases were prospectively followed up for the occurrence of major adverse cardiac events.</p><p><b>RESULTS</b>Totally 25 patients received stent implantation, 2 received balloon dilation followed by coronary artery bypass graft, and 1 patient died during PCI. Total in-hospital mortality was 35.7% (10/28), and mortality was 53.3% (8/15) in cardiac shock patients. Compared with survival group, ratio of cardiac shock [80.0% (8/10) vs.38.9% (7/18), P < 0.05] and poor collateral circulation flow [100% (10/10) vs. 33.3% (6/18), P < 0.01] were higher in death group, and there was no significant difference in TIMI 3 grade of forward flow post procedure (P > 0.05). Hospital stay was (22.1 ± 2.6) days and the cumulative survival was 64.3% during 3 months follow up for survival group.</p><p><b>CONCLUSIONS</b>Short-term clinical outcome is favorable for survived AMI patients with left main disease who underwent PCI. The ratio of cardiac shock and poor collateral circulation flow are risk factors for in-hospital death in AMI patients with left main disease who underwent PCI.</p>

<p><b>BACKGROUND</b>Primary percutaneous coronary intervention (PCI) is the best treatment of choice for acute ST segment elevation myocardial infarction (STEMI). This study aimed to determine the clinical outcomes of tirofiban combined with the low molecular weight heparin (LMWH), dalteparin, in primary PCI patients with acute STEMI.</p><p><b>METHODS</b>From February 2006 to July 2006, a total of 120 patients with STEMI treated with primary PCI were randomised to 2 groups: unfractionated heparin (UFH) with tirofiban (group I: 60 patients, (61.2 ± 9.5) years), and dalteparin with tirofiban (group II: 60 patients, (60.5 ± 10.1) years). Major adverse cardiac events (MACE) during hospitalization and at 4 years after PCI were examined. Bleeding complications during hospitalization were also examined.</p><p><b>RESULTS</b>There were no significant differences in sex, mean age, risk factors, past history, inflammatory marker, or echocardiography between the 2 groups. In terms of the target vessel and vascular complexity, there were no significant differences between the 2 groups. During the first 7 days, emergent revascularization occurred only in 1 patient (1.7%) in group I. Acute myocardial infarction (AMI) occurred in 1 (1.7%) patient in group I and in 1 (1.7%) in group II. Three (5.0%) patients in group I and 1 (1.7%) in group II died. Total in-hospital MACE during the first 7 days was 4 (6.7%) in group I and 2 (3.3%) in group II. Bleeding complications were observed in 10 patients (16.7%) in group I and in 4 patients (6.7%) in group II, however, the difference was not statistically significant. No significant intracranial bleeding was observed in either group. Four years after PCI, death occurred in 5 (8.3%) patients in group I and in 4 (6.7%) in group II. MACE occurred in 12 (20.0%) patients in group I and in 10 (16.7%) patients in group II.</p><p><b>CONCLUSIONS</b>Dalteparin was effective and safe in primary PCI of STEMI patients and combined dalteparin with tirofiban was effective and safe without significant bleeding complications compared with UFH. Although there was no statistically significant difference, LMWH decreased the bleeding complications compared with UFH.</p>

<p><b>OBJECTIVE</b>To study the differential microRNAs expression between patients with essential hypertension and healthy controls.</p><p><b>METHODS</b>Whole blood from 15 hypertensive patients and 5 controls healthies were separated into plasma at 3000 rpm for 10 minutes. MicroRNAs were harvested using kit, and stored at -80°C. MicroRNAs profiling were performed using Exiqon microRCURY(TM) LNA microRNAs array, and were quantitative RT-PCR for the differential microRNAs expression. In addition, we used a set of plasma samples from 24 hypertensive patients and 22 healthy donors to independently validate the expression of these signature microRNAs.</p><p><b>RESULTS</b>MicroRNAs expression profile was found to be differentially in the essential hypertensive patients compared with the healthy donors. Of 1700 microRNAs detected on the microarray, 46 microRNAs were found to be differentially expressed in the essential hypertensive patient, 27 microRNAs were collected in Sanger microRNAs data-bank, the function of remaining 19 microRNAs were unknown. In the 27 microRNAs, 9 microRNAs were up-regulated in the hypertension patient samples, while 18 known microRNAs were down-regulated. MiR-296-5p (Fold change 0.47, P = 0.013) and miR-133b (Fold change 0.57, P = 0.033) were consistently down-regulated in the patient plasma, whereas let-7e (Fold change 1.62, P = 0.009) and hcmv-miR-UL112 (Fold change 2.72, P = 0.004), one human cytomegalovirus encoded microRNAs, were up-regulated in the patient samples. The microRNAs expression was independently validated using another sample. We showed that MHC class I polypeptide-related chain B (MHC class I polypeptide-related chain B, MICB) and Interferon regulatory factor 1 (Interferon regulatory factor 1, IRF1) were functional targets of hcmv-miR-UL112 by fluorescent reporter assays.</p><p><b>CONCLUSIONS</b>The hypertensive patients have distinct microRNAs expression Profile. Hcmv-miR-UL112 may have important implications toward pathogenesis of essential hypertension.</p>
