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

Percutaneous transluminal coronary angioplasty (PTCA) was done successfully in 33 patients,6 of them were associated with 8 acute coronary events. Radioimmunoassay was used for the determination of plasmaET,AII and CGRP levels. The samples were drawn successively from femoral artery just before PTCA and 0min, 15min,1h,3h,24h after the final balloon inflation. The results showed that the levels of plasma AII were higher in the complication group than those of noncomplication group before PTCA and 0min, 24h after PTCA. The differences in plasma ET levels before and after PTCA between the complication group and the non-complication group were not significant. The level of plasma CGRP was decreased at 15min and returned to basal level at 1h after PTCA in the complication group.In the patients without complication,there were no significant differences in their plasma CGRP levels before and after PTCA. All + ET/CGRP in the complication group raised more rapidly,recovered later and the peak appeared earlier than that of non-complication group. For a better understanding pathophysiologic meaning of the above changes,further studies are needed.

There were no data concerning restenosis rate after percutaneous transluminal coronary angio-plasty available in China so far. Our study was focused on clinical and angiographic follow-up and tried to reveal the predictive value for angiographic restenosis using noninvasive tests among 592 patients whose 841 coronary arteries were dilated in our department from Dec. 1987 to Dec. 1994.This patient group consisted of 503 males and 89 females had average age of 58. 4 ? 9. 1. The overall success rate was 93. 3% and acute vessel complications was 4. 1%. After successful procedures of PTCA,the patients were followed up with recurrence of angina, Holler ECG, submaximal excercise ECG and 99mTc-MIBI exercise scintigraphy regularly. 62 of these patients underwent coronary angiographic follow-up from 4-24 months (average time: 10. 4 ? 7. 6 months) after PTCA. We found 35 patients with angiographic restenosis and 27 patients without. Thus, we divided the patients into restenosis group and non-restenosis group according to the angiographic results. Subsequently, we oberserved whether the symptom and noninvasive tests were valuable in prediction of restenosis. The result showed that recurrence of angina, Holter ECG, submaximal exercise ECG and 99mTc-MIBI scintigraphy were useful in detecting restenosis with their specificity and sensitivity 75.7% and 72.0%, 71. 4% and 86. 7%, 66. 7% and 73. 1% ,76. 5% and 83. 3 %, respectively. Moreover, If any two of above four ischemic indexes were combined together to detect restenosis,the specificity and sensitivity were significantly enhanced (85. 2% and 92. 9%). It is concluded that recurrence of angina and the noninvasive tests were valuable in predicting restenosis. The combination of these ischemic indexes would greatly improve their predictive value.
