All the complications from 535 patients undergoing selective coronary artery angiogram by using Judkins method have been documented during and after the procedures and compared with collected data from Chinese papers published before 1999.The main complications included death, acute myocardial infarction,acute heart failure, severe arrhythmia,and peripheral vessel complication.In 535 patients the main complication rate was 2 99%(16 of 535),in which ventricular fibrillation rate accounted for 0 37%(2 of 535),severe bradycardia for 1 31%(7 of 535),and peripheral vessel complications for 1 31%(7 of 535).There was no death,no AMI, no heart failure,no artery embolus,no aortic dissection.Compared with 3 01% (141 of 4679) of complications for collected data from domestic literature,there was no significant difference.The data suggested that with effective preventive measures,coronary artery angiogram is a reasonably safe proceduce,although there is still a possibility to have server complications.

Objective To study the significance of plasma brain natriuretic peptide(BNP)in differentiating patients with chronic cor pulmonale from those with hypertensive heart failure.Methods Thirty cases of cor pulmonale and 30 of hypertensive heart disease were recruited for the study.Heart rate and arterial partial oxygen pressure(PaO2)were measured for them,as well as plasma level of BNP Was measured by rapid immunofluorescence quantitative analysis.with 30 normal healthy persons as controls.ResultsAs compared with the control group.plasma level of BNP increased significantly in patients with chronic cor pulmonale and hypertensive heart failure(P＜0.05),and that in those with hypertensive heart failure[(597±68)ng/L]Was significantly higher than that in those with cot pulmonale[(179±34)ng/L,P＜0.05].Conclusion Plasma level of BNP can be used as an indicator to differentiate cor pulmonale from hypertensive heart failure both with dyspnea.

Objective To evaluate the clinical and coronary angiographic features of non-Q wave and Q wave myocardial infarction in the elderly. Methods The clinical history(including hypertension and diabetes), complication and in-hospital mortality, blood lipid, serum CK-Mb, LVEF, and the record of the coronary stenosis by angiography 3-4 weeks after infarction were investigated in non-Q wave and Q wave myocardial infarction patients. Results The clinical history and blood lipid did not differ significantly between the NQMI and QMI patients. NQMI patients had a significantly lower maximal peak 〔(68.7?18.6) mmol/L vs (108.6?17.3)mmol/L, P0.05), but occlusion rate of infarct-related vessels in NQMI patients were lower. Conclusions Prognosis of NQMI patients is better than that of QMI patients in acute-phase, and the occlusion rate of infarct-related vessels in NQMI patients were lower.

Objective To evaluate the role of intra-aortic balloon pumping(IABP) in high risk patients with acute myocardial(AMI).Methods The clinical data of all patients with acute myocardial infarction treated with IABP admitted into the first affiliated hospital to PLA General Hospital from January 2004 to May 2008 was collected.The efficacy of the IABP was evaluated. Results A total number of 23 patients with acute myocardial infarction were treated with IABP.17patients received revascularization therapy. Death rate was 30.4%.Conclusion IABP is safe in high risk patients with AMI who represented poor hemodynamic status or cardiogenic shock,and it can sufficiently stablieze the hemodynamic status,improve cardiac function and can decrease in-hospital mortality.

Objective To observe the characteristics of the two-dimensional global strain index in patients with different degrees heart failure with speckle tracking echocardiography. Methods Totally 35 myocardial infarction patients with heart failure and 28 healthy subjects (control group) were enrolled in the study. The patients were divided into mild (n=14), moderate (n=13), and severe heart failure subgroup (n=8) according to left ventricular ejection fraction (LVEF). The systolic longitudinal strain (LS), radial strain (RS) and circumferential strain (CS) were measured of left ventricular with two-dimensional speckle tracking technique. The average value of left ventricular 18 segmental LS, RS and CS was calculated as the global longitudinal strain (GLS), the global radial strain (GRS) and the global circumference strain (GCS), respectively. LVEF and left ventricular end diastolic volume (LVEDV) were also measured with conventional two-dimensional echocardiography. The global two-dimensional strain and heart function between two groups were compared. The change of GLS, GRS and GCS of different heart failure and the relationship between them and LVEF were analyzed. Results Compared with control group, GLS, GRS and GCS reduced in heart failure groups (P<0.01). In heart failure groups, GLS significantly decreased with the decrease of LVEF, the difference of GLS was significant (P<0.05). GCS in severe heart failure subgroup was lower significantly than that in mild and moderate heart failure subgroups (P<0.05). No significant difference was found in GCS between mild and moderate heart failure subgroups (P>0.05). There was no significant difference in GRS among heart failure subgroups (P>0.05). GLS was closely correlated to LVEF (r=-0.65, P<0.01), GCS was also correlated to LVEF (r=-0.55, P<0.01). Conclusion The changes of GLS, GRS and GCS is different in different degrees of heart failure. GLS is closely correlated to the change of LVEF. The change of GLS, GRS and GCS may reflect degrees of myocardial injury.
