Objective To explore the diagnostic value of Holter monitoring for coronary heart disease (CHD) in diabetic and non-diabetic patients. Methods 188 patients with coronary heart disease were divided into diabetic group(n=65)and non-diabetic group(n=123). The diagnostic sensitivity, specificity, accuracy and other indices of Holter monitoring for CHD were compared between the two groups according to the results of angiography and Holter monitoring. Logistic regression analysis was applied to analyze the factors affecting holter ST-segment change. Results The sensitivity of Holter monitoring for diagnosing CHD in diabetic group was higher than that in non-diabetic group(P=0.046). There was an association between the positive ST-segment change and number of stenosal arteries, diffuse arterial lesion and complete vessel occlusion respectively (OR=2.36, 4.91, 3.90). Conclusion Although the sensitivity and specificity of Holter monitoring for diagnosing coronary heart disease were low, it remains some diagnostic value for coronary heart disease in diabetic patients.

Objective To demonstrate the effect on platelet aggregation rate (PAR) and clinical outcomes of tirofiban in patients undergoing emergency percutaneous coronary intervention (PCI) and to evaluate its safety. Methods Thirty patients presenting with STEMI and had received emergency PCI were enrolled into the tirofiban group. By means of matching, another 30 patients who received elective PCI during the same period from September 2005 to March 2006 were enrolled as the control in the 2nd Xiangya Hospital of Central South University. Patients in the tirofiban group received tirofiban infused at 10 ?g/kg within 3 minutes as bolus 10-30 minutes pre-operation followed by infusion at 0.15 ?g/(kg?min) for 36 hours. The control group received the same dosage of placebo. All patients received intravenous heparin and oral ADP receptor antagonist and aspirin. PAR, incidence of 7 and 30 days composite end point events (death, persistent myocardial ischemic, reinfarction and target vessel revascularization) and bleeding complications were observed in both groups. Results Compared with the control group, the tirofiban group showed a decrease in PAR (19?8)% vs (54?7)%, P

OBJECTIVE:
To retrospectively evaluate the efficacy of stent-delayed implantation in patients with acute myocardial infarction (AMI) with high thrombus burden after thrombus extraction was performed.
METHODS:
Of 186 consecutive AMI patients, 56 were included according to thrombus score(TS)>or=2, and then were divided into 2 groups based on the thrombus score after thrombus extraction was executed: the stent-direct implantation group (TS=0 or 1)and the stent-delayed implantation group (TS>or=2) even if 3 times thrombus extraction were given. Thrombolysis in myocardial infarction(TIMI)flow grade and TIMI myocardial perfusion (TMP) were used to assess the coronary artery flow and myocardial perfusion,respectively.
RESULTS:
TIMI score in the stent-direct implantation group was lower than that in the stent-delayed implantation group. There was no significant difference(P=0.07). TMP score in the stent-direct implantation group was significantly lower than that in the stent-delayed implantation group (P<0.05).
CONCLUSION
Stent-delayed implantation can remarkably improve myocardial perfusion in AMI patients with high thrombus burden after thrombus extraction and intensive anti-thrombosis therapy is administrated.

OBJECTIVE:
To explore the cause of cardiac perforation and tamponade during cardiac catheterization and intervention and to evaluate the effectiveness of the emergency treatment for tamponade in our hospital.
METHODS:
The clinical data from 23, 319 patients who received diagnostic catheterization or therapeutic procedures were analyzed retrospectively.
RESULTS:
Cardiac perforation and cardiac tamponade were observed in 22 of the 23, 319 patients during catheter procedures. It includes 1 in coronary artery angiography, 9 in percutaneous balloon mitral valvuloplasty, 3 in diagnosis, 2 in congenital heart disease intervention, 2 in pacemaker implantation, 2 in atrial fibrillation ablation and the other 3 in coronary revascularization. The occurrence of cardiac perforation in 11 patients was related to puncture of the interatrial septum and/or the procedure in the left atrial procedure and 2 were related to high pressure injection. Seventeen patients were found cardiac tamponade in the process of catheterization, and 5 were found at 2-14 h after operation. Pericardiocentesis and pericardial catheter drainage were performed in 20 patients and 11 of them succeeded. Among the other 11 patients, 7 were successfully saved by thoracotomy and 4 died.
CONCLUSION
Cardiac tamponade is a severe and fatal complication that may occur in different catheter procedures. Early prevention and diagnosis and performingperi cardiocentesis and drainage timely are critical to reduce the mortality.

Unroofed coronary sinus syndrome (UCSS), also named coronary sinus septal defect, is a rare type of atrial septal defect with the incidence less than 1% of the total number of atrial septal defects. It is caused by incomplete formation of left atrial venous folds during embryonic development. Here we reported a patient with UCSS, who was treated in the Second Xiangya Hospital of Central South University. The patient was 50 years old and the main clinical manifestations were fatigue and shortness of breath after repeated exercise. Color Doppler echocardiography showed coronary sinus dilatation (17 mm×14 mm), indicating the possibility of permanent left superior vena cava. Pulmonary angiography showed that the left ventricle and coronary sinus were developed at the same time while the atrial septum was intact after the development of the left atrium, followed by the right atrium and right ventricle, indicating a partial anomalous pulmonary venous drainage (intracardiac type). Finally, the cardiac computed tomograhic angiography showed that 4 pulmonary veins and permanent left superior vena cava (PLSVC) went into the left atrium and the coronary sinus, respectively, while the coronary sinus septum was absent and the PLSVC was connected with the left atrium. The patient was later treated with the correction of non-parietal sinus syndrome in the Cardiovascular Surgery Department of our hospital.
