In 21th century, percutaneous coronary intervention (PCI) technique enters in rapid development stage in China. From 2009, quality control system of PCI runs in national scale. Since then, the national quality control center estab?lished cooperative relationship with the provincial quality control centers. Official website and quality control tools were im?proved. PCI data were collected and analyzed annually, and then reported to the regulatory body and published to the public. Audit was run irregularly. Quality control centers were also involved in some other related affairs such as training course and admission. The quality control system lead PCI in China to an improved daily practice and control PCI application all overthe country in terms of data. In the future, the quality control techniques and teamwork will be further improved. And quality evaluation system and management team will be perfected gradually. Quality control will be extended from PCI to coronary heart disease and combined with audit of coronary heart disease. According to the quality control data, the quality and its rank of medical centers will be published in certain range. So that we can provide better care to the coronary heart disease pa?tients.

Objective:To investigate the association of renal insufficiency and clinical outcomes in patients with acute coronary syndrome(ACS). Methods: The study was a multi-centre register study including 3 589 ACS patients coming from 39 centers across China who had received percutaneous coronary intervention(PCI) prior to 1st February, 2007. Estimated glomerular filtration rate (eGFR) was calculated for all patients using the 4-variable MDRD equation with the serum creatinine obtained before angiography. The association between renal insufficiency and clinical outcomes and the presence of in-hospital death and bleeding was studied by Fisher’s exact test. Multi-variable analysis on the risk factors of in-hospital bleeding was done by logistic regression test. Results: The mean age of the study population was (61.74?11.37) years (ranging from 23 years to 92 years)and 76.5% (2 746/3 589) of the population was male. Only 90 patients (2.51%) were known to have chronic kidney disease at the time of admission and 144 patients(4.01%) had serum creatintine levels above 133 ?mol/L. However, after the evaluation of renal status by the MDRD equation, 2 250 patients (63.1%)showed a reduction in eGFR of less than 90 mL/min, of whom, 472 (13.1%) even reached the level of moderate renal insufficiency (eGFR

Objective To evaluate the effectiveness and safety of a new designed balloon catheter, the Minirail balloon catheter in coronary intervention Methods Twenty two consecutive patients with coronary artery disease (male 16, female 6, mean age 58 77?8 69 years) were enrolled the study Selective angioplasty was performed for 24 target lesions (17 in LAD, 2 in LCX, and 5 in RCA) Among these target lesions were 5 type C, 14 type B 2, and 5 type B 1 lesions The average extent of narrowing before procedure was 91 18%?5 95% Target lesions were dilated with Minirail balloon catheters Results All of the target lesions were successfully dilated with Minirail balloon catheters The average residual stenosis was 33 18%?25 14% after balloon angioplasty Significant dissection was seen in 3 of the cases, and slow reflow in another one Twenty four stents were implanted in 19 cases The final residual stenosis was 1 82%?5 01% at the end of procedure No death or Q wave myocardial infarction happened No emergency bypass surgery needed Conclusion Minirail balloon catheter is safe, effective, and easy to be used in coronary intervention

Objective To study the clinical significance of molecular markers and routine coagulation tests in patients with cerebral infarction and to set up a serial programs of laboratory diagnosis,monitoring and treatment of cerebral infarction.Methods Prothrombin fragment 1+2(F1+2),thrombin antithrombin III complex(TAT), D-dimer(D-D),Von willebrand Factor(vWF),antithrombin(AT), protein C(PC),prothrombin time(PT),activated partial thromboplastin time(APTT) and thrombin time (TT) were determined in 90 patients with cerebral infarction and 60 normal control subjects.Results The levels of F1+2,TAT,D-D,vWF were significantly higher in patients with cerebral infarction than that in control subjects. But the levels of PC,AT,PT,APTT,TT in patients with cerebral infarction were no different from that in control subjects.Conclusion There were hypercoagulable states in patients with cerebral infarction.The activity of prothrombin is higher, thrombin is generated more, the activity of fibrinolysis is higher too, but anticoagulation system is not sufficiently activated .Meanwhile, perhaps endothelial lesion would be the main role of coagulation system activating and pathogenesis.Molecular markers such as F1+2,TAT,D-D,VWF can be as diagnositic signs but routine coagulable tests can not display the hypercoagulable states in patients with cerebral infarction.
