RESUMO
Objective To investigate the expression of histone deacetylase(HDAC)isoforms in the frontal lobe,hippo-campus and liver of offspring rats delivered by rats with maternal immune activation and their correlation with the efficiency of prepulse inhibition(PPI%).Methods Ten pregnant Sprague-Dawley rats were randomly divided into the model group(n=5)and control group(n=5).The rats in the model group were injected with 10 mg·kg-1 polyinosinic-polycytidylic acid(Poly I:C)via the caudal vein on the 9th day of pregnancy,while rats in the control group were given the same volume of sterile physiological saline.After 3 h,blood was collected from the caudal vein,and the levels of interleukin(IL)-1 β,IL-6 and tumor necrosis factor-α(TNF-α)in the plasma of pregnant rats were detected by enzyme-linked immunosorbent assay to evaluate the immune activation status.The pregnant rats in the two groups were fed until natural delivery,the offspring rats were weaned on the 21st day after birth,and the male offspring rats were fed continuously.A prepulse inhibition test was performed at puberty(the 40th day after birth)to evaluate the spatial recognition memory and sensory gating function of the offspring rats.The expression levels of the HDAC gene family in the hippocampus,frontal lobe and liver of offspring rats were detected by real-time fluorescence quantitative polymerase chain reaction.Results The plasma IL-6,IL-1 β and TNF-α levels in the model group were significantly higher than those in the control group(P<0.05).When the prepulse stimulation was 75 dB,the PPI%of the offspring rats at puberty in the model group was significantly lower than that in the control group(P<0.05).When the prepulse stimulation was 80 and 85 dB,there was no significant difference in PPI%between the model group and the control group(P>0.05).In the frontal lobe,the expression levels of HDAC3,HDAC4,HDAC8,HDAC9,HDAC10 and Sirt mRNA in the offspring rats in the model group were significantly lower than those in the control group(P<0.05),while the expression level of HDAC5 mRNA was significantly higher than that in the control group(P<0.05);there were no significant differences in the expression levels of HDAC1,HDAC2,HDAC6,HDAC7 and HDAC11 mRNA between the model group and the control group(P>0.05).In the hippocampus,the offspring rats in the model group had significantly lower expression levels of HDAC1,HDAC8 and HDAC10 mRNA and significantly higher expression levels of HDAC2 and HDAC5 mRNA than those in the control group(P<0.05);there were no significant differences in the expression levels of HDAC3,HDAC4,HDAC6,HDAC7,HDAC9,HDAC11 and Sirt mRNA between the model group and control group(P>0.05).In the liver tissue,the expression levels of HDAC6 and HDAC10 mRNA of the offspring rats in the model group were significantly lower than those in the control group(P<0.05);there were no significant differences in the expression levels of HDAC1,HDAC2,HDAC3,HDAC4,HDAC5,HDAC7,HDAC8,HDAC9,HDAC11 and Sirt mRNA between the model group and the control group(P>0.05).The expression level of HDAC2 mRNA in the hippocampus of offspring rats in the two groups was negatively correlated with PPI%at 75 dB(r=-0.965,P<0.05),the expression levels of HDAC10 and Sirt mRNA in frontal lobe tissues were positively correlated with PPI%at 75dB(r=0.946,0.925;P<0.05).Conclusion Pregnancy Poly I:C infection has significant effects on the expression of HDAC family proteins in offspring rats,and which is related to the impairment of early sensory gating,this may provide new ideas for the research in pathogenesis and drug treatment of schizophrenia.
RESUMO
Objective To analyze the composition and change of the disease spectrum of inpatients in a third-level women's and Children's Hospital in Foshan City,so as to provide evidence for the prevention and treatment of common diseases among local women and children and promote the development of maternal and child health work.Methods The primary diagno-sis and other medical data of home page of inpatients from 2013 to 2022 were collected and classified according to the Internation-al Classification of Diseases(ICD-10),and the changes of age,gender and disease spectrum of hospitalized patients in different discharge year groups were compared.Results The average increase rate of patients discharged from hospital in 2022 compared with 2013 is 9%.The majority of discharged patients were female adults,accounting for 65.2%.Adult female patients are mainly hospitalized for pregnancy,childbirth and puerperium,neoplasms,and genitourinary diseases,the composition of gynecological neoplasms and genitourinary diseases increased.Most of the hospitalized children were boys,with a sex ratio of 1.9 ∶1.Respirato-rydiseases and some conditions originating in the perinatal period in the decade from 2013 to 2022 were in the top two of the dis-ease spectrum of pediatric patients,and the ranking of Symptoms,signs and anomal clinical and laboratory findings,not else-where classified and neurological diseases increased rapidly.Conclusion Pregnancy,childbirth,puerperal and other special fe-male health conditions are still the main reasons for female hospitalization.It is necessary to continue to guarantee medical re-sources and strengthen the diagnosis and treatment ability of female tumor.Children's respiratory diseases and certain conditions originating in the perinatal period are still disciplines that need to be focused,while children's neurological diseases also need to continue to focus on due to their rapid growth.
RESUMO
Objective The aim of this study is to investigate the efficacy of using transcatheter aortic valve replacement(TAVR)with self-expanding valve(SEV)to treat patients with pure aortic regurgitation(PAR)and to understand the preliminary experience of such procedure.Methods A total of 20 PAR patients who underwent TAVR using the TaurusElite system at Wuhan Asia Heart Hospital and Wuhan Asia Heart Disease Hospital from April 2022 to May 2023 were included in the study.Patient baseline data,echocardiographic data,follow-up data during hospitalization and 30 days after the procedures were collected and analyzed.Results The mean age of the patients was(73.5±5.5)years,and the mean STS score was(8.7±3.6)%.16(16/20)cases had severe PAR before the procedure.After TAVR treatment,the success rate of the procedure was 20/20,with only 1 case of valve-in-valve(ⅥⅤ).The 30-day follow-up results showed that none of the 20 patients experienced death,disabling stroke,myocardial infarction,and conversion to surgery.The degree of residual PAR after the procedure was none or mild in all patients.The interventional outcome was ideal.Conclusions The preliminary experience shows that,with strict patient selection and standardized procedural steps,using TAVR with SEV to treat patients with PAR could have high feasibility and ideal early clinical outcomes and can potentially be popularized.Such experience will be further validated in future clinical trials.
RESUMO
Objective:To provide theoretical reference for the construction of effective prevention and control strategies. The study deeply investigates the impact of traumatic birth events on compassion fatigue and inner feelings of midwives.Methods:Fifteen midwives from five tertiary hospitals in Guangzhou were interviewed in depth by semi-structured interview method from April to June 2021. Colaizzi analysis and Nvivo12 plus software were used to analyze and integrate the data and extract themes.Results:Three main themes were extracted, including the characteristics of traumatic birth events (high incidence, sudden and dangerous, preventable and controllable); exacerbating compassion fatigue (reducing compassion satisfaction levels; exacerbating burnout; and aggravating traumatic stress responses); and exploring effective coping strategies (time required for adjustment, seeking stress release).Conclusions:As a strong stressor, traumatic birth events aggravate the symptoms of compassion fatigue in midwives. Managers should pay attention to the occupational exposure of traumatic childbirth events, actively guide midwives to make psychological adjustments. In addition, managers can increase social support and strengthen the ideological and political education of midwives, so that they have good stress tolerance and excellent professional psychological quality.
RESUMO
Objective:A case-control association analysis was performed to investigate if the single nucleotide polymorphisms (SNPs) of N-cadherin(CDH2) gene is implicated in schizophrenia in a Han Chinese population.Methods:A total of 528 patients with paranoid schizophrenia and 528 healthy controls were recruited from northern Henan province to analyze 25 SNPs located in CDH2 gene.The clinical symptoms of 267 first-episode schizophrenia patients were evaluated with positive and negative syndrome scale (PANSS), and the correlation between CDH2 gene and clinical symptoms was analyzed by SNPStats software online.Results:Allele frequencies of rs9951577 and rs1231268 were significantly correlated with schizophrenia( P<0.05), genotype frequency of rs1639387 was significantly correlated with schizophrenia( P=0.044). After gender classification, SNPs rs1789470 and rs28365328 were found to be significantly correlated with schizophrenia in female patients ( P=0.044, 0.019). In addition, the study found that CDH2 was correlated with the clinical characteristics of schizophrenia( P<0.05), and the negative factor score of patients between GG type rs1231268 and the other two genotypes (AG+ AA) ((21.12±8.41) vs (18.87±7.52)) was statistically significant ( P<0.05). Conclusion:CDH2 gene may be one of the susceptibility genes to SZ, and has definite correlation with clinical negative symptoms.
RESUMO
AIM: To assess the biosafety of a poly(acrylamide-co-sodium acrylate) hydrogel (PAH) as a 3D-printed intraocular lens (IOL) material. METHODS: The biosafety of PAH was first evaluated in vitro using human lens epithelial cells (LECs) and the ARPE19 cell line, and a cell counting kit-8 (CCK-8) assay was performed to investigate alterations in cell proliferation. A thin film of PAH and a conventional IOL were intraocularly implanted into the eyes of New Zealand white rabbits respectively, and a sham surgery served as control group. The anterior segment photographs, intraocular pressure (IOP), blood parameters and electroretinograms (ERG) were recorded. Inflammatory cytokines in the aqueous humor, such as TNFα and IL-8, were examined by ELISA. Cell apoptosis of the retina was investigated by TUNEL assay, and macroPAHge activation was detected by immunostaining. RESULTS: PAH did not slow cell proliferation when cocultured with human LECs or ARPE19 cells. The implantation of a thin film of a 3D-printed IOL composed of PAH did not affect the IOP, blood parameters, ERG or optical structure in any of the three experimental groups (n=3 for each). Both TNFα and IL-8 in the aqueous humor of PAH group were transiently elevated 1wk post-operation and recovered to normal levels at 1 and 3mo post-operation. Iba1+ macroPAHges in the anterior chamber angle in PAH group were increased markedly compared to those of the control group; however, there was no significant difference compared to those in the IOL group. CONCLUSION: PAH is a safe material for 3D printing of personal IOLs that hold great potential for future clinical applications.
RESUMO
Objective To evaluate the safety and effectiveness of drug-eluting stents (DES)implanted in the main branch(MB)of the coronary artery combined with drug-coated balloon(DCB)inflation in the side branch(SB)in patients with coronary bifurcation lesions.Methods A total of 68 patients with true coronary bifurcation lesions(Medina 1,1,1;1,0,1;0,1,1) admitted into our hospital from June 2017 to June 2018 were enrolled in this single center observation study.Patients were treated with DES MB implantation and DCB SB inflation,and were followed up and assessed with quantitative coronary angiography(CAG)at 6 months after PCI.The primary endpoints were late lumen loss(LLL)of MB and SB at 6 months after PCI.Results DES was implanted in MB in 68 patients.DCB was used in SB in 67 patients,and DES was implanted in SB in 1 patient due to TIMI 1 flow in SB after predilation.The rate of residual stenosis was (8.9 ± 5.6) % in MB and (19.7 ± 6.2)% in SB immediately after PCI.Of 68 patients,type A dissection occurred in 7 cases and type B dissection in 5 cases in MB immediately after PCI.Overall 64 patients were followed up and assessed with quantitative CAG at 6 months after PCI.The LLL of MB was (0.25±0.31)mm and the LLL of SB was-(0.12±0.38)mm.All patients' SB dissection disappeared,and 1 patient died due to cerebral hemorrhage at 2 months after PCI.The 30-day main adverse cardiac events(MACE)was 0,and 6-month MACE was 5.97%,in which 2 cases had angina pectoris at about 3 months after PCI,with CAG showing in-stent restenosis(ISR)in the left anterior descending coronary artery(LAD)and good SB.DCB was used to treat ISR.LAD was good when assessed with CAG at 6 months during follow-up.Myocardial infarction occurred in 2 cases at about 4 months after PCI,but not in the target-vessel.Conclusions DES MB implantation combined with DCB SB inflation is safe and effective in treating coronary bifurcations lesions.

RESUMO
BACKGROUND: Previous Caucasian studies have described venous thromboembolism in pregnancy; however, little is known about its incidence during pregnancy and early postpartum period in the Chinese population. We investigated the risk of venous thromboembolism in a “real-world” cohort of pregnant Chinese women with no prior history of venous thromboembolism. METHODS: In this observational study, 15,325 pregnancies were identified in 14,162 Chinese women at Queen Mary Hospital, Hong Kong between January 2004 and September 2016. Demographic data, obstetric information, and laboratory and imaging data were retrieved and reviewed. RESULTS: The mean age at pregnancy was 32.4±5.3 years, and the median age was 33 years (interquartile range, 29–36 yr). Pre-existing or newly diagnosed diabetes mellitus was present in 627 women (4.1%); 359 (0.7%) women had pre-existing or newly detected hypertension. There was a small number of women with pre-existing heart disease and/or rheumatic conditions. Most deliveries (86.0%) were normal vaginal; the remaining were Cesarean section 2,146 (14.0%). The incidence of venous thromboembolism was 0.4 per 1,000 pregnancies, of which 83.3% were deep vein thrombosis and 16.7% were pulmonary embolism. In contrast to previous studies, 66.7% of venous thrombosis occurred in the first trimester. CONCLUSION: Chinese women had a substantially lower risk of venous thromboembolism during pregnancy and the postpartum period compared to that of Caucasians. The occurrence of pregnancy-related venous thromboembolism was largely confined to the early pregnancy period, probably related to the adoption of thromboprophylaxis, a lower rate of Cesarean section, and early mobilization.

<p><b>Background</b>Serum soluble ST2 (sST2) levels are elevated early after acute myocardial infarction and are related to adverse left ventricular (LV) remodeling and cardiovascular outcomes in ST-segment elevation myocardial infarction (STEMI). Beta-blockers (BB) have been shown to improve LV remodeling and survival. However, the relationship between sST2, final therapeutic BB dose, and cardiovascular outcomes in STEMI patients remains unknown.</p><p><b>Methods</b>A total of 186 STEMI patients were enrolled at the Wuhan Asia Heart Hospital between January 2015 and June 2015. All patients received standard treatment and were followed up for 1 year. Serum sST2 was measured at baseline. Patients were divided into four groups according to their baseline sST2 values (high >56 ng/ml vs. low ≤56 ng/ml) and final therapeutic BB dose (high ≥47.5 mg/d vs. low <47.5 mg/d). Cox regression analyses were performed to determine whether sST2 and BB were independent risk factors for cardiovascular events in STEMI.</p><p><b>Results</b>Baseline sST2 levels were positively correlated with heart rate (r = 0.327, P = 0.002), Killip class (r = 0.408, P = 0.000), lg N-terminal prohormone B-type natriuretic peptide (r = 0.467, P = 0.000), lg troponin I (r = 0.331, P = 0.000), and lg C-reactive protein (r = 0.307, P = 0.000) and negatively correlated to systolic blood pressure (r = -0.243, P = 0.009) and LV ejection fraction (r = -0.402, P = 0.000). Patients with higher baseline sST2 concentrations who were not titrated to high-dose BB therapy (P < 0.0001) had worse outcomes. Baseline high sST2 (hazard ratio [HR]: 2.653; 95% confidence interval [CI]: 1.201-8.929; P = 0.041) and final low BB dosage (HR: 1.904; 95% CI, 1.084-3.053; P = 0.035) were independent predictors of cardiovascular events in STEMI.</p><p><b>Conclusions</b>High baseline sST2 levels and final low BB dosage predicted cardiovascular events in STEMI. Hence, sST2 may be a useful biomarker in cardiac pathophysiology.</p>

Objective To compare 12-month follow-up clinical outcome of an early to a delayed intervention in the management of high-risk non-ST elevation acute coronary syndrome (NSTE-ACS) patients. Methods 758 consecutive high-risk NSTE-ACS patients treated with percutaneous coronary artery intervention(PCI)were enrolled between Jauary 2015 and December 2015 in Wuhan Asia Heart Hospital. They were divided into 2 groups according to diff erent intervention time, the early PCI group(within 24 h after diagnosis,n=185)and the delayed group (more than 24 h after diagnosis, n=573).The baseline clinical data, angiographic features, data related to PCI, the 12-month follow-up major adverse cardiac events (MACE) were analyzed retrospectively. MACE were defi ned as all-cause death and recurrent nonfatal myocardial infarction. Results Primary endpoint status after 12-month follow-up were collected in 711 of 758 initially enrolled patients. Incidence of MACE was 14.5% in the early and 11.2% in the delayed PCI group(χ2=1.289,P=0.256). No signifi cant diff erences were found in the occurrence of the individual components of all-cause death and nonfatal myocardial infarction. Mean hospital stay were(7.6±3.1)d in the early and (10.7±3.8)d in the delayed PCI group(t=2.489,P=0.014). Mean medical expenses in RMB were(48.5±13.5) thousand yuan in the early and(52.8±16.4)thousand yuan in the delayed PCI group(t=2.132,P=0.038). Conclusions After 12-month follow-up,no diff erence in incidence of MACE was seen between early and delayed invasive strategy,but with shorter hospital stay and reduced medical expenses.
RESUMO
Objective To compare 5-year clinical outcomes of the safety and efficacy of zotarolimus-eluting stent(ZES)and everolimus-eluting stent(EES).Methods A total of 480 patients receiving either ZES(n=244)or EES(n=236)placement from January 2011 to December 2012 in Wuhan Asia Heart Hospital were included in this study.The primary end point of the study was 5-year all-cause mortality including acute myocardial infarction,and target vessel revascularization after the index EES/ZES placement.The secondary end points included subsequent in-stent restenosis and in-stent occlusion at 5 years.Results There were no significant differences in all-cause mortality and acute myocardial infarction outcomes between the ZES and the EES groups(P>0.05).Compared with patients receiving EES,patients receiving ZES had a significantly higher rate of 5-year target vessel revascularization(10.2%vs.5.1%,P=0.040),in-stent restenosis(11.5%vs.5.9%,P=0.036),and in-stent occlusion(6.1%vs.2.1%,P=0.038).Conclusions At 5 years,patients receiving EES generally had better or comparable long-term outcomes compared with patients receiving ZES.

Objective To study the effect of levosimendan on cardiomyocyte apoptosis after coronary microembolization (CME) in swine,Methods Fifteen healthy swines were randomly divided into sham operation group,CME group and levosimendan treatment group (5 in each group).Their cardiac function was assessed by echocardiography,their cardiomyocyte apoptosis was assyed with TUNEL staining,and Caspase-3 expression was detected by Western blot at 12 h after operation.Results The LVEF was lower,the left ventricular minor axis was shorter and the cardiac output volume was smaller while the LVEDD was longer in CME group than sham operation group (P<0.05).The cardiac function was significantly better in CME group than in sham operation group (P<0.05).The cardiomyocyte apoptosis rate and Caspase-3 expression level were significantly higher in CME group than in sham operation group (P<0.05).The cardiomyocyte apoptosis rate was significantly higher while the Caspase-3 expression level was significantly lower in levosimendan treatment group than in CME group (6.820%±-1.974 % vs 10.558%±2.425%,P<0.05).Conclusion Pretreatment with levosimendan can effecively reduce the cardiomyocyte apoptosis and improve the cardiac function after CME by inhibiting the Caspase-3 expression in cardiomyocytes.
RESUMO
Objective: To preliminarily investigate the relationship between the baseline level of serum soluble ST2 (sST2) and 30-day MACE occurrence rate in patients with ST-elevation myocardial infarction (STEMI). Methods: A total of 121 patients with confirmed diagnosis of STEMI in our hospital from 2015-05-01 to 2015-07-30 were consecutively enrolled. According to baseline sST2 level, the patients were divided into 2 groups:Low sST2 group, the patients with sST2≤56.68 ng/ml, n=61 and High sST2 group, the patients with sST2>56.68 ng/ml, n=60. Clinical condition and 30-day MACE (defined as death and new onset of congestive heart failure) occurrence rate were compared between 2 groups. Results: ① The systolic blood pressure (SBP), Killip class≥II grade, blood levels of cTNI, NT-proBNP, hs-CRP and LVEF were different between 2 groups, all P56.68 ng/ml was the risk factor for 30-day MACE occurrence (HR=1.152, 95%CI 1.078-1.231, P=0.000). Conclusion: Increased baseline level of sST2 implied the higher incidence of death and new onset of congestive heart failure in STEMI patients.
RESUMO
Objective To investigate the risk factors that may induce pneumothorax resulted from subclavian vein puncture during interventional therapy for arrhythmia.Methods The clinical data of 4 351 patients with heart disease,who were admitted to Wuhan Asia Heart Disease Hospital,China,during the period from January 2010 to January 2014 to receive subclavian vein puncture for the performance of radiofrequency catheter ablation or pacemaker implantation,were retrospectively analyzed.The gender,age,presence of chronic obstructive pulmonary disease (COPD) and the shape of clavicle of patients who developed pneumothorax were analyzed,and their relationships with the occurrence of pneumothorax were evaluated.Results Of the 4 351 patients,47 patients developed pneumothorax(1.08%),their age was 12-72 years old with a mean of (47.1±18.4) years old.Among the 47 patients,37 patients were females (78.7%).The angle between clavicle and sternum <60°(oblique clavicle) was seen in 27 patients,coexisting COPD was seen in 2 patients.The occurrence of pneumothorax was strikingly higher in females than that in males (OR=2.7,95% CI=1.4-5.2).In patients with oblique clavicle the risk of pneumothorax was obviously increased (OR=3.5,95% CI=1.6-7.9) and in patients with COPD the probability of pneumothorax was remarkably increased (OR=2.3,95%CI=1.2-4.7).No special treatment was employed in 5 pneumothorax patients,and the pneumothorax was absorbed by itself.In 19 patients,the pneumothorax was relieved through thoracic puncture and suction.Closed drainage of thoracic cavity was employed in 23 patients.All patients were discharged from hospital with complete rehabilitation.Conclusion Clinically,pneumothorax has been an important clinical problem in interventional therapy.In female patients and in patients who have oblique clavicle or coexisting COPD,pneumothorax is more likely to occur when they receive subclavian vein puncture.

RESUMO
A multi-functional microfluidic chip with multi-orifice flow fractionation ( MOFF) and magnetic capture technique was developed to specifically separate and capture the HepG2 cells in artificial samples. The chip contained a glass substrate and a polydimethylsiloxane ( PDMS) microchannel cover plate. The PDMS cover plate consisted of 3 injection channels of 10-mm-long, a MOFF separation zone and a hexagonal cavity cell enrichment-detection zone. Among which, the MOFF separation zone had a total length of 20 mm and was consisted of 80 semi-rhombic shrinkage / expansion units with a length of 0. 18 mm, a depth of 50 μm, a shrinkage area width of 0. 06 mm, and an expansion area of 0. 20 mm. The angle between each group of shrinkage / expansion units was 103. 0°. In this experiment, HepG2-blood cell suspension was used as the sample. Based on the principle that the magnetic bead surface-modified c-Met antibody could specifically bind to HepG2 cells, an immunomagnetic bead ( Anti-MNCs) suspension at a concentration of 50 μg / mL was prepared by surface carboxylated beads, EDC (1 mg / mL), NHS (1 mg / mL) and c-Met antibody. Under the optimized flow rate (50 μL/ min), a few HepG2 in suspension samples were efficiently captured at the detection zone of chip via a magnetic field; the carbon quantum dots were prepared by microwave heating with citric acid and thiourea to label HepG2 cells which achieved in-situ fluorescence visualization of captured HepG2. Cells captured in the chip detection area were counted by microscope. The capture rate of HepG2 cells was 88. 5% ±6. 7% (106 blood cells and 10 HepG2 cells per 500 μL). The results demonstrated that the developed multifunctional microfluidic chip may serve as a promising tool for separation and capture of tumour cells.
RESUMO
Objective To observe high residual platelet reactivity in patients with acute coronary syndrome and diabetes mellitus receiving dual antiplatelet therapy with clopidogrel or ticagrelor and its influence on prognosis. Methods A total of 175 patients with acute coronary syndrome and diabetes mellitus in Wuhan Asia Heart Hospital were included in this retrospective study, and all patients were divided into two groups : ticagrelor group ( n = 22 ) and clopidogrel group ( n = 153 ) . The platelet aggregation function was tested by light transmission platelet aggregation (LTA). The high residual platelet reactivity was defined as maximum platelet aggregation rate ﹥46. 0%. The differences of high residual platelet reactivity and the effect of high residual platelet reactivity on cardiovascular events were compared between the two groups. Results The number of patients with high residual platelet reactivity in the clopidogrel group were 99 patients (64. 7%), and 8 patients(36. 4%) in the ticagrelor group (P=0. 011) . For stent thrombosis developed in three months, 3 patients were from the high residual platelet reaction group ( n=107 ) , none from the normal residual platelet reaction group ( n =68 ) ( P =0. 016 ) . For bleeding events at 3 months, there were 2 patients (1. 9%, 2/107) from the high residual platelet reaction group and 2 patients (2. 9%, 2/68) were from the normal residual platelet reaction group (P=0. 631). Conclusions Ticagrelor significantly decreases high residual platelet reactivity than clopidogrel. High residual platelet reactivity increases stent thrombosis risk for ACS and type 2 diabetes mellitus.
RESUMO
Objective: To study clinical characteristics and anatomical distributions of pulmonary embolism (PE) in suspicious PE patients and to explore if CT coronary angiography (CTCA) may simultaneously exclude PE. Methods: A total of 403 consecutive patients with suspicious PE admitted to cardiology department of our hospital from 2013-01 to 2014-10 were retrospectively studied. According to embolus distribution by CT pulmonary angiography (CTPA) and CTCA, the patients were divided into 2 groups: PE group,n=261 and Non-PE group,n=142. The clinical symptoms and imaging characteristics were analyzed and compared between 2 groups. Results: The overall prevalence of PE was 64.8% (261/403), suspicious PE patients were all with chest distress, palpitation, chest pain and syncope. Compared with Non-PE group, the patients in PE group were with more female gender and palpitation, while less chest pain,P0.05. In PE group, the sign of emboli were found in 245/261 patients (93.9%) at CTCA scanning area, the rest 16 patients (6.1%) had the small area of PE, and the emboli were only located at both upper pulmonary arteries. Conclusion: In patients with dififculty of breath, palpitation, chest pain and syncope, coronary artery disease (CAD) and PE should be simultaneously considered for accurate diagnosis. CTCA may meanwhile ifnd PE during CAD diagnosis.
