Objective:To explore the feasibility of screening for major fetal heart disease by training sonographers in township or county level hospitals .Methods:Training of B ultrasound scan for congeni-tal heart defects was given to the sonographers from one county hospital , and thirteen township hospitals ( or the district hospitals ) , and training of fetal echocardiography was given to sonographers from four city/county hospitals.The trained sonographers who had passed the examinations and had obtained quali-fications after six months of independent practice began to screen fetal congenital heart defects .To evalu-ate the effectiveness , sensitivity and specificity of screening was calculated by using the diagnosis of ex-pert neonatal/fetal echocardiographers as the gold standard .Results: A total of 3 425 fetuses received one fetal B ultrasound screening , one fetal echocardiography and one neonatal echocardiography from April 1, 2004 to December 31, 2005.One hundred and sixty-five B ultrasound screening images (4.9%) from township hospitals and fifty-six fetal echocardiography images (1.7%) from county or city centers couldn ’ t be reviewed because of poor quality .The sensitivity of fetal B ultrasound screening in the township and county hospitals was 30%and 0, and the specificity 93.3%and 99.9%, respectively. Nine fetuses with a major congenital heart disease were eventually found by the trained sonographers , and two cases were misdiagnosed and two unnoticed .The total sensitivity and specificity of fetal echocardio-graphy were 81.8% and 99.9%, respectively.The sensitivity in the county and city hospitals was 66 .7% and 100%, respectively .The specificity in the county and city hospitals was 99 .9%and 100%, respectively .Conclusion: Under the current circumstances , township hospitals are unable to perform effective fetal cardiac screening .Screening on fetal congenital heart disease is suggested to be taken by trained sonographers in county and city level medical centers .

Objective To evaluate the effect of the percutaneous transluminal septal myocardial ablation(PTSMA)on the left ventricular function in patients with hypertrophic obstructive cardiomyopathy(HOCM).Methods All HOCM patients underwent echocardiogram measurements before and after the PTSMA procedure.The peak velocity of mitral annulus was measured at Doppler tissue pulsed wave mode.Doppler tissue imaging(DTI)was obtained at the 4- and 2-chamber apical view,and the peak systolic(Sa),early diastolic(Ea),and late diastolic(Aa)myocardial velocities of mitral annulus was measured at the long apical view.Results Compared with the velocity parameters before the PTSMA procedure,the peak Sa and Ea after the PTSMA were significantly lower while Aa was un-significantly lower.Conclusions In patients with HOCM,the diastolic and systolic function of the left ventricle decreased after the PTSMA procedure.

(0.05)). The sensitivity and the agreement rate were best at dose of Dob 10 ?g?kg~(-1)?min~(-1) with (86.5)% and (86.5)% (Kappa(0.71)), respectively. When Isoket combined with Dob 3,5 ?g?kg~(-1)?min~(-1), the sensitivities and the agreement rates were both significantly improved than either one used (both P

OBJECTIVETo evaluate the change of endothelin-1 (ET-1) in the mini-swine model of acute myocardial infarction (AMI) and reperfusion and the effect of Tongxinluo (TXL) on it, and to explore the possible mechanism of no-reflow.

METHODSForty mini-swines were randomized into 5 groups: the model group, the small,middle and large dose of TXL groups and the sham-operated group, 8 in each group. The AMI reperfusion model was established by coronary ligation for 3 hrs followed with relaxation for 1 hr. Plasma ET-1 content before and after AMI, and after reperfusion was determined respectively by radioimmunoassay. The ET-1 mRNA expression in myocardial tissue of normal, ischemic and no-reflow area were respectively quantified by reverse transcription-polymerase chain reaction.

RESULTS(1) Compared with before AMI, levels of plasma ET-1 at the time points of 5 min and 3 hrs after AMI, 5 min and 1 hrs after reperfusion in the model group were significantly raised, showing an increasing tendency (all P < 0.01). But the increment in the middle and large dose of TXL groups were all lower than that in the model group (P < 0.05). (2) In the model and the TXL groups, levels of ET-1 in myocardial tissue of ischemic and no-reflow area were significantly higher than those in the normal area, and the increment in no-reflow area was higher than that in ischemic area (all P < 0.01). Compared with the model group, significant lowering of ET-1 in ischemic area was only shown in the middle and large dose of TXL groups (P < 0.01). (3) In the model and the TXL groups, ET-1 mRNA expression in ischemic area was significantly higher (all P < 0.01), while it in no-reflow area was significantly lower than that in the normal area respectively (all P < 0.01). The raised ET-1 mRNA expression in the middle and large dose TXL groups was significantly lowered when compared with that in the model group (P < 0.01).

CONCLUSIONThe endothelium injury might be one of the important mechanisms for no-reflow phenomenon. TXL might reduce the no-reflow by protecting endothelium cells. was significantly higher (all P < 0.01), while it in no-reflow area was significantly lower than that in the normal area respectively (all P < 0.01). The raised ET-1 mRNA expression in the middle and large dose TXL groups was significantly lowered when compared with that in the model group (P < 0.01). Conclusion The endothelium injury might be one of the important mechanisms for no-reflow phenomenon. TXL might reduce the no-reflow by protecting endothelium cells.

Objective: To investigate the short-term outcome of patients with acute myocardial infarction complicating cardiogenic shock due to left main disease. Methods: A total of 24 patients with acute myocardial infarction complicating cardiogenic shock due to left main artery disease hospitalized in Fuwai hospital from June 2012 to May 2018 were included. The clinical data were analyzed,and the patients were divided into survivor group (11 cases) and death group (13 cases) according to survival status at 28 days post the diagnosis of shock. The patients were further divided into thrombolysis in myocardial infarction(TIMI) flow grade 0-2 group (11 cases) and TIMI flow grade 3 group (13 cases) according to TIMI flow grade after the procedure. The patients were then divided into non-three-vessel lesions group (14 cases) and three-vessel lesions group (10 cases) according to coronary angiography results. Results: Compared with survivor group, patients in death group presented with lower worst systolic blood pressure within 24 hours after admission (50(48, 70) mmHg (1 mmHg=0.133 kPa) vs. 73(70, 80) mmHg, P<0.01), lower worst diastolic blood pressure with in 24 hours after admission ((33.5±12.4) mmHg vs. (48.9±9.4) mmHg, P<0.01), higher respiratory rates ((27.3±2.5) times/min vs. (21.5±4.0) times/min, P<0.01), less 24 hours urine output ((422±266) ml vs. (1 680±863) ml, P<0.01), lower platelet counts ((161.9±81.9)×10⁹/L vs. (241.6±94.0)×10⁹/L, P=0.03), higher serum creatinine ((250.0±36.8) μmol/L vs. (132.7±34.2) μmol/L, P<0.01), higher alanine aminotransferase (288(76,846) IU/ml vs. 81(42, 109) IU/ml, P=0.04), lower artery pH (7.11±0.17 vs. 7.39±0.09, P<0.01), higher lactic acid ((10.29±3.62) mmol/L vs. (4.21±2.85) mmol/L, P<0.01), higher incidence of invasive ventilation (7/13 vs. 2/11, P=0.02), higher scores of acute physiology and chronic health evaluation (APACHE) Ⅱ (35.4±6.8 vs. 18.7±1.7, P<0.01) and simplified acute physiology score (SAPS) Ⅱ (73.5±17.4 vs. 47.0±4.3, P<0.01), and higher incidence of target vessel TIMI flow grade 0-2 (10/13 vs. 1/11, P<0.01). Kaplan-Meier survival curve analysis showed that survival rate at 28 days post the diagnosis of shock in TIMI flow grade 3 group was higher than that in TIMI flow grade 0-2 group (76.9% vs. 9.1%, log-rank test, P<0.01), and mortality rate was similar at 28 days post the diagnosis of shock between non-three-vessel lesions group and three-vessel lesions group (35.7% vs. 60.0%, log-rank test, P=0.14). Multivariate logistic regression analysis showed that compared with TIMI flow grade 0-2 group, the OR value of death at 28 days post the diagnosis of shock in TIMI flow grade 3 patients with acute myocardial infarction complicating cardiogenic shock due to left main disease was 0.030(95%CI 0.003-0.340, P<0.01). Conclusion Short-term outcomeof patients with acute myocardial infarction complicating cardiogenic shock due to left main disease remains poor, and final flow of TIMI grade 3 is confirmed as independent protective factor of death at 28 days post the diagnosis of shock in these patients.

Objective: To investigate the association between APOB gene R532W polymorphism and the risk of coronary heart disease (CHD) in patients without lipid-lowering treatment and to analyze the interactions between the variation of R532W and different risk factors of CHD. Methods: CHD and non-CHD were diagnosed according to coronary artery angiography (CAG) and/or coronary computed tomography angiogram (CTA) results, as well as clinical features. Blood samples from 771 CHD patients and 772 age- and sex-matched non-CHD controls, who never accepted any lipid-lowering treatments, were collected. R532W was genotyped by HumanExome BeadChip at BGI and strict quality control was made. Firstly, the association between R532W polymorphism and the risk of CHD in 3 genetic models (GA+ AA vs.GG, AA vs. GG+ GA, AA vs. GA vs. GG) after adjusting confounding factors was explored. Then, the interactions between the variation of this loci and risk factors related to CHD were investigated. Results: (1) Total cholesterol (TC) levels were significantly lower in AA genotype than in GA genotype in the total cohort and non-CHD controls, but was similar among the 3 genotypes in CHD patients. (2) R532W GG, GA and AA distribution was 80.7%, 18.2% and 1.2% in CHD patients, and 74.6%, 23.8% and 1.6% in non-CHD controls (P<0.05). (3) R532 polymorphism was related to the incidence of CHD in the dominant model, and A-allele carriers were related to about 35% reduced risk of CHD (OR=0.653, 95% CI 0.502-0.849, P=0.001) after adjusting for confounding factors. (4) R532W polymorphism had positive interactions with hypertension (1.452) and smoke (1.077), while negative interaction with diabetes (0.553) in the occurrence of CHD. Conclusions APOB gene R532W polymorphism is related to TC levels in Chinese north Han population. A-allele carries of R532W loci is linked with reduced risk of CHD in the absence of lipid-lowering treatment. R532W polymorphism has a positive additive interaction with hypertension and smoke, while a negative additive interaction with diabetes mellitus in the occurrence of CHD.

Objective: To investigate the efficacy of bare metal stent for treating focal coronary artery aneurysm complicating with severe stenosisin single coronary artery. Methods: This retrospective analysis was performed in 7 patients who were diagnosed as local coronary artery aneurysm complicating with severe stenosis(≥70%) in single coronary artery and treated with bare metal stent during the period from December 2012 to June 2015 in Fuwai Hospital. All 7 patients were male with age of (62±11) years old. During the interventional operation, the narrow parts were pre-expanded,and all patients received bare metal stents implantation to cover aneurysms.The clinical and imaging data of patients immediately post procedure and at postoperative follow-up were collected to evaluate the clinical efficacy. Results: There were 5 cases of left anterior descending aneurysms and 2 cases of right coronary artery aneurysms. The diameter of aneurysm was (5.21±1.28)mm, and the length was (13.71±3.88)mm. There was intracranial vortex in coronary arteriography immediately after intervention.Proximalstenosis of coronary artery aneurysm was disappeared,and the distal blood flow was TIMI class 3.There were no signs of aortic dissection and thrombus formation.During 6(6 16) months follow-up, the aneurysms were disappeared,and there were no major adverse cardiovascular events which including myocardial ischemia, acute myocardial infarction, revascularization,bleeding,and death for all patients. Conclusion Initial experience shows that double-layer bare metal stents implantation for patients with localized coronary artery aneurysm complicating with severe stenosis in single vessel is safe and effective.

Objective: To compare predictive value of the current 7 scoring systems and CADILLAC-plus scoring system for risk of short-term deathin patients with acute myocardial infarction complicating cardiogenic shock. Methods: A total of 126 acute myocardial infarction patients complicating cardiogenic shock hospitalized in Fuwai hospital from June 2014 to January 2018 were enrolled in this study, the clinical data were retrospectively analyzed. The patients were divided into survival group(49 cases) and death group(77 cases) according to survival or not at 28 days after diagnosis of cardiogenic shock.The scores of APACHE Ⅱ,APACHE Ⅲ,SAPS Ⅱ,PAMI, TIMI-STEMI,TIMI-NSTEMI,and CADILLAC were calculated within 24 hours in coronary care unit (CCU),and scores of CADILLAC-plus, which is an improved score derived from CADILLAC, was also calculated. The predictive value of the different scoring systems for 28 day smortality of acute myocardial infarction patients complicating cardiogenic shock were compared in this patient cohort. Results: Scores of APACHEⅡ,APACHEⅢ,SAPSⅡ,PAMI,TIMI-STEMI, TIMI-NSTEMI,CADILLAC,and CADILLAC-plus were all significantly higher in death group than in survival group: (28.9±10.2 vs. 21.8±8.3,94.0 (57.0,114.0) vs. 57.0 (45.4,81.5) ,62.0 (46.0,81.0) vs. 47.0 (41.5,60.5) ,7.0 (6.0,9.0) vs. 6.0 (6.0,7.5) ,10.0 (9.0,11.0) vs. 9.0 (8.0,10.0) ,4.0 (3.0,5.0) vs. 3.0 (3.0,4.0) ,10.0 (7.0,12.0) vs. 7.0 (5.0,9.0) ,and 10.0 (8.0,14.0) vs. 7.0 (5.0,10.0) , respectively, all P<0.01).The area under the curve(AUC) of receiver operating characteristic(ROC) curve for predicting 28 days death of APACHE Ⅱ,APACHE Ⅲ,SAPS Ⅱ,PAMI, TIMI-STEMI,TIMI-NSTEMI,and CADILLAC scoring systems were 0.820,0.797,0.785,0.667,0.657,0.711,and 0.821,respectively and cut-off value was 27.5,79.5,66.0,8.5,10.5,3.5,and 8.5, respectively and the sensitivity was 0.766,0.844,0.649,0.494,0.494,0.740,and 0.753, respectively and specificity was 0.816,0.755,0.837,0.204,0.796,0.571,and 0.755,respectively.The AUC of ROC of CADILLAC-plus scoring system was 0.885,cut-off value was 9.5, sensitivity was 0.896,and specificity was 0.735. The predicting efficacy of CADILLAC-plus scoring system was superior to other scoring systems. Conclusion The 7 current scoring systems are all suitable for predicting theshort-term death in acute myocardial infarction patients complicating cardiogenic shock, and the predicting efficacy of the improved CADILLAC-plus score is superior to other scoring systems in this patient cohort.

OBJECTIVEThe clinical features of patients with mediastinal and/or neck hematoma after transradial cardiac catheterization were reviewed and analyzed to help the clinicians to recognize this complication, and try their best to avoid the complication and treat the complication properly.

METHODSA total of 8 patients with mediastinal and/or neck hematoma after right transradial cardiac catheterization in Fuwai hospital from January 1, 2005 to the end of 2012 were included in this study. Among these 8 patients, 1 patient underwent coronary angiography, 7 patients underwent percutaneous coronary intervention and drug eluting stents were successfully implanted in 6 patients. The clinical data of these patients were analyzed retrospectively.

RESULTSSuper slide hydrophilic guild-wire was used in all patients. These patients felt chest pain, dyspnea and neck pain and neck or throat tightness after the procedure. CT scan was performed in all 8 patients and reviewed mediastinal hematoma, 4 patients complicated with neck hematoma, and suspicious laceration on the right subclavian artery or branch of innominate artery were found in 2 patients. Post procedure hemoglobin decrease was evidenced in all 8 patients. Anti-platelet therapy was discontinued until discharge in 2 patients, dual anti-platelet drugs were transiently discontinued or underwent dosage reduction in 4 patients, protamine was administered in 2 patients to neutralize heparin. Blood transfusion was not required, there was no stent thrombosis, and surgery was not indicated for all 8 patients. No complication was reported during follow up.

CONCLUSIONSMediastinal and/or neck hematoma is a rare complication post transradial catheterization approach. This complication is caused by super slide guild-wire or catheter's injury of small vessels near the aortic arch or subclavian artery, especially with rough manipulation. Neck and mediastinal CT scan should be performed as early as possible for patients with suspect hematoma and prognosis is usually fine with suitable therapy.
