Objective: To explore the changing features of plasma amino-terminal pro-B-type natriuretic peptide (NT-proBNP) level in patients with hypertrophic obstructive cardiomyopathy (HCM) after alcohol septal ablation (ASA). Methods: A total of 82 HCM patients treated by ASA in our hospital were studied. According to plasmalevel of NT-proBNP, the patients were divided into 2 groups: High NT-proBNP group and Low NT-proBNP group,n=41 in each group. Plasma NT-proBNP was examined by ELISA; ventricular septal thickness (VST), left ventricular posterior wall thickness (LVPWT), maximal ventricular wall thickness (MLVWT) and left atrial diameter (LAD) were measured by echocardiography. There were 50 patients ifnished 1 year clinical or in-hospital follow-up, their NT-proBNP level and echocardiography were detected at 2 days and 1 year post-operation.The relationship between echocardiography parameter and NT-proBNP level was assessed; NT-proBNP was compared between pre- and 2 days, 1 year post-operation. Results:①In all 82 patients: compared with Low NT-proBNP group, High NT-proBNP group had increased VST (23.66±6.46) mm vs (20.79±4.56) mm,P=0.035, LVPWT (12.79±2.99) mm vs (11.50±2.35) mm,P=0.048, MLVWT (28.03±5.66) mm vs (25.18±4.81) mm,P=0.027 and LAD (40.73±4.86) mm vs (38.08±6.17) mm,P=0.049.②In 50 patients who ifnished 1 year follow-up study: compared with pre-operation, NT-proBNP level was slightly increased at 2 days post-operation (1841.79±1310.88) fmol/ml vs (1552.15±951.57) fmol/ml,P=0.066, while decreased at 1 year post-operation (1038.46±714.03) fmol/ml vs (1552.15±951.57) fmol/ml,P=0.000. Conclusion: Plasma NT-proBNP level was affected by atrial size and ventricular thickness in HCM patients, it may obviously decrease during long-term follow-up period.

Objective To analyze the correlation between septal branch characteristics and the prognosis of alcohol septal ablation ( ASA ) in patients with hypertrophic obstructive cardiomyopathy . Methods The clinical , echocardiographic , angiographic and procedural characteristics were analyzed retrospectively in 55 patients.Good prognosis was defined as left ventricular outflow tract gradient decreased by 50%at long term follow-up.The characteristics of septal branch were analyzed in terms of QCA .Results There were no differences in the length of the ablated septal branch , sizes of the adjacent branches , distances between the septal branch and the ostia of the coronary arteries and the volume of alcoholo consumed ( all P>0.05).Compared with poor prognosis group (n =27), the diameter of the ablated septal branches were significantly larger in the good prognosis group ( n=28 ) [ ( 1.75 ±0.36 ) mm vs.( 1.48 ±0.41 ) mm, P=0.012].The distance between the ablated branch and its adjacent branch was farer in the good prognosis group [(18.80 ±10.20)mm vs.(13.04 ±6.65)mm, P=0.020].In multivariate analysis, the diameter of the ablated branch (OR 9.258,95%CI 1.427-60.069, P=0.020)and the distance between the ablated septal branch and its adjacent septal branch (OR 1.102,95% CI 1.002-1.213, P =0.046) were found to be independent risk factors for good prognosis of ASA .Conclusions The diameter of the ablated septal branch and the distance between its adjacent septal branch are associated with better prognosis of ASA .

Objective:To explore the relationship between big endothelin-1 (big ET-1) and cardiac remodeling in patients with hypertrophic obstructive cardiomyopathy (HOCM).
Methods:A total of 167 consecutive HOCM patients admitted in our hospital from 2015-01 to 2016-05 were enrolled. Blood levels of big ET-1 and NT-proBNP were measured;electrocardiogram(ECG), dynamicECG,echocardiography (UCG) and cardiovascular magnetic resonance (CMR) were examined for relevant statistical analysis.
Results:In all 167 HOCM patients, blood level of Big ET-1 was positively related to NT pro-BNP (r=0.35, P=0.000), left atrial (LA) diameter (r=0.169, P=0.019) and heart rate (r=0.141, P=0.037);negatively related to hemoglobin (r=-0.173, P=0.013) and the ratio of interventricular septum (IVS)/posterior wall of left ventricle (r=-0.165, P=0.017). Based on the finding of positive correlation between Big ET-1 and LA diameter, the patients were divided into 2 groups:Normal LA group, n=74 and Enlarged LA group, n=93. Compared with Normal LA group,Enlarged LA group had the higher blood level of Big ET-1 (P=0.001);increased left ventricular end-diastolic diameter (LVEDD) (P=0.024), thicker IVS (P=0.003), lower LVEF (P=0.001);enlarged LVED volume (P=0.002) and IVS (P=0.002);elevated ratio of atrial fibrillation(AF);more patients with moderate to severe mitral regurgitation (MR) and NYHA functional classIII/IV.
Conclusion: Blood level of Big ET-1 was positively related to NT pro-BNP and LA diameter in HOCM patients;the patients with enlarged LA had increased Big ET-1, more obvious cardiac remodeling and the higher incidence of AF occurrence which implied that Big ET-1 might play the role in cardiac remodeling in HOCM patients.

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,

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.
