【摘要】 目的 探討血尿酸水平、頸動脈斑塊與冠心病之間的關系。 方法 收集2006年1月-2009年12月擬診為冠心病的住院患者280例,冠狀動脈造影檢查冠狀動脈狹窄程度gt;50%的194例為冠心病組,冠狀動脈無狹窄或狹窄程度lt;50%的86例為對照組;冠心病組又分為單支、雙支、多支病變亞組。分別測定冠心病組與對照組頸總動脈與頸動脈分叉處內膜中層厚度(IMT)、等級評分、Crouse積分、血尿酸濃度。結果 與對照組相比,冠心病組頸總動脈與頸動脈分叉處IMT、等級評分、Crouse積分、血尿酸濃度均高于對照組,差異有統計學意義。在冠心病組,隨病變分支的增多,頸動脈超聲檢查指標與血尿酸隨之升高(Plt;0.05或0.01)。 結論 頸動脈IMT、等級評分、Crouse積分、血尿酸濃度與冠心病相關,是冠心病的獨立危險因素。【Abstract】 Objective To investigate the relationships between serum uric acid levels, carotid artery plaque and coronary heart disease (CHD). Methods 194 patients with CHD and 86 nonCHD patients were selected through coronary angiography in patients with essential hypertension. CHD group was divided into three subgroups including a single branch, doublebranch and multivessel disease. Intimamedia thickness (IMT) of carotid artery and carotid bifurcation, grade score, Crouse score, serum uric acid concentrations were detected in patients with coronary heart disease and control group. Results IMT of carotid artery and carotid bifurcation, grade score,crouse score, serum uric acid concentrations were higher in CHD group than that in control group, and the difference was statistically significant. In the CHD group, ultrasound parameters of carotid artery and serum uric acid increased with the increase in branch lesions (Plt;005 or 001). Conclusions Carotid IMT, grade score, Crouse score, serum uric acid concentration relate to coronary heart disease, which is an independent risk factor for coronary heart disease, respectively.
Objective To compare the clinical early results of on-pump and off-pump coronary artery bypass grafting re-operations (re-CABG)and introduce our experience. Methods From April 2000 to June 2006, 21 cases with coronary artery diease of re-CABG were performed in this hospital. 10 patients received off-pump CABG (off-pump group), and 11 underwent CABG re-operations with cardiopulmonary bypass CABG(on-pump group). There were no significant difference regarding gender, age, weight, diabetes, hypertension, left ventricular end-diastolic dimension (LVEDD) and left ventricular ejection fraction (LVEF) between two groups before operation. On-pump CABG procedures were performed on hypothermia cardiopulmonary bypass. Standard methods were used to finish off-pump CABG. Flow meters were utilized to measure the flow of grafts in both groups. Results No one in off-pump group needed to conver to on-pump CABG. There was no operative or late mortality. The operation time, respiratory support time, the volume of chest tube drainage, blood transfusion and postoperative hospital stay were less in off-pump group than those in on-pump group after operation. Early death occurred in 1 patient in on-pump group. The number of distal anastomosis were more in on-pump group than that in off-pump group. Conclusions Both off-pump CABG and on-pump CABG can be applied to CABG re-operations and achieved similar completeness of revascularization, similar early surgical results.
Objective To evaluate the efficacy of normalization management on prognosis in elderly patients with coronary artery disease, in aspects of drug compliance, readmission rate and quality of life. Methods A total of 110 patients above 65 years old with coronary artery disease visiting West China Hospital from August 2010 to February 2011 were investigated. The patients were divided into two groups: the intensive management group (n=55) and the general management group (n=55). The measures such as regular follow-up, regular examination and medical education were conducted in the intensive management group, and the two groups were observed in aspects of drug compliance, readmission rate and quality of life. Results After 1-year follow-up, the percentages of patients taking aspirin/clopidogrel (98.18% vs. 67.27%, Plt;0.05), nitrate (85.45% vs. 40.00%, Plt;0.05), ACEI/ARB (56.36% vs. 18.18%, Plt;0.05), β receptor blocker (58.18% vs. 29.09%, Plt;0.05) and statin (94.55% vs. 32.73%, Plt;0.05) were higher in the intensive management group than those in the general management group. Also, the readmission rate was lower (12.73% vs. 41.42%, Plt;0.05) and the score of quality of life was higher in the intensive management group than that in the general management group. Conclusion The normalization management guided by evidence-based medicine for the elderly patients with coronary artery disease is helpful to improve the drug compliance, reduce the readmission rate, and improve the quality of life.
【摘要】 目的 通過建立活體大鼠心肌缺血再灌注模型,模擬人類冠心病,研究聚合血紅蛋白(PolyHb)在心肌缺血再灌注中的保護作用,探究PolyHb在冠心病領域中的保護和治療作用。 方法 將45只Sprague-Dawley(SD)大鼠隨機分成3組:實驗組(15只)、對照組(15只)、假手術組(15只),建立大鼠心肌缺血模型。實驗組建立動物模型后,結扎冠狀動脈35 min,并于結扎后5 min,通過SD大鼠尾靜脈按1 mL/min的速度注射1 mL(100 g/L)的PolyHb溶液。缺血完成后開放灌注120 min。對照組建立動物模型,結扎冠狀動脈35 min,并于結扎后5 min,通過SD大鼠尾靜脈按1 mL/min的速度注射1 mL生理鹽水。缺血完成后開放灌注120 min。假手術組僅建立動物模型,但不結扎冠狀動脈,也不再灌注。比較3組SD大鼠的血流動力學參數左室內壓最大上升和下降速率、心肌酶(血清肌酸激酶、乳酸脫氫酶)及病理學檢查(梗死心肌占總心肌面積的百分比),來衡量PolyHb的作用。 結果 與對照組比較,用PolyHb處理的實驗組可增強再灌注時左室內壓最大上升和下降速率(Plt;0.05),減少血液中血清肌酸激酶和乳酸脫氫酶的含量(Plt;0.05),并明顯減少心肌梗死面積百分比(Plt;0.05)。 結論 在心肌缺血的SD大鼠中,PolyHb可以有效的降低缺血再灌注損傷,從而達到心肌保護作用。【Abstract】 Objective To investigate the protective effect of polymerized hemoglobin (PolyHb) for myocardial ischemia-reperfusion and explore the field of polymerized hemoglobin in the protection and treatment of human coronary heart disease, by simulating human coronary heart disease and establishing myocardial ischemia-reperfusion model in living rats. Methods Forty-five Sprague-Dawley (SD) rats were randomly divided into 3 groups: experimental group (n=15), control group (n=15), and sham operation (SHAM) group (n=15). Rat models of myocardial ischemia-reperfusion were established. For the rats in the experimental group, we ligated their left coronary artery for 35 minutes, and injected 1 mL (100 g/L) PolyHb solution into their body at a speed of 1 mL/min 5 minutes later. After ischemia was completed, reperfusion was performed for 120 minutes. The procedures carried out for the rats in the control group were exactly the same except that the PolyHB solution was replaced by 1 mL saline solution. Ligation of the artery and reperfusion were not performed on the rats in the SHAM group. Hemodynamic parameters (maximal rising and falling rates of left ventricular pressure), enzymes (serum creatine kinase, lactate dehydrogenase) and results of histopathologic examinations (percentage of myocardial infarction area over the total myocardial area) were measured and compared among the three groups to evaluate the function of PolyHb. Results Compared with the control group, the experimental group treated with PolyHb had higher maximum rising and falling rates of left ventricular pressure (Plt;0.05), lower blood levels of creatine kinase and lactate dehydrogenase (Plt;0.05), and lower percentage of myocardial infarction area over the total myocardial area (Plt;0.05). Conclusion Polymerized hemoglobin can effectively reduce the ischemia-reperfusion injury and achieve myocardial protection in SD rats with myocardial ischemia.
Objective To assess the quality of randomised controlled trials on traditional Chinese medicine (TCM) for coronary heart disease (CHD) angina published from 1977 to 2002. Method We did electronic search in Medline, Embase and hand searched 83 journals of traditional Chinese medicine (the earliest published in 1977 and the latest in June 2002). We assessed the quality of obstained studies. Results Four hundred and forty articles met the criteria,of which 33 (7.5%) described randomization. None of them mentioned allocation concealment; 94.77% (417 studies) mentioned diagnosis criteria; only one mentioned the calculation basement of sample size; 84.09% (370 studies) mentioned comparability of baseline. Fifty three studies (12.05%) noted double-blind; 28 studies used single blind. Twenty-five studies used double-blind. Drop-outs were described in 7 cases without intention-to-treat (ITT); 159 studies applied statistical methods properly, while 4 did not. Ten studies never mentioned statistical methods; 73.18% (322 studies) used forms to express their results. Conclusions Till now, the quantity and quality of RCTs of traditional Chinese medicine for coronary heart disease angina were inadequate. Some well designed scientific methods were not adequately applied.

Methods:We analyzed eGFR in the patients with coronary artery disease confirmed by coronary angiography and the control, and compared the proportion of patients with reduced renal function in the different groups. Results: A total 116 cases were included in each group. Among these patients, normal renal function, mildly and severe reduced renal function was documented in 82, 29 and 5 in coronary artery disease group, and in 98, 13 and 5 in the control group, respectively. In comparison to the control, more patients with reduced eGFR were found in coronary artery disease group (χ2 value 7.517,P=0.023), although no significant difference was observed between both groups(Pgt;0.05). Conclusion: Reduced eGFR, even if mildly, could be regarded as the risk factor of coronary artery disease.
