临床 SYNTAX 积分和 SYNTAX 积分预测复杂冠状动脉性心脏病 患者经皮冠状动脉介入治疗预后的对比研究

目的比较临床SYNTAX积分和SYNTAX积分对冠状动脉性心脏病(简称冠心病)3支病变和/或左主干病变患者经皮冠状动脉介入治疗(PCI)预后的预测作用。方法回顾性分析2007年1月至2008年12月北京安贞医院经造影证实3支病变和/或左主干病变并接受PCI治疗的患者。对每例患者进行SYNTAX积分和临床SYNTAX积分,通过门诊或电话随访患者主要不良心脑血管事件(MACCE),包括全因死亡、非致命性心肌梗死、再次血运重建、中风等。结果符合入选条件的患者总计190例,其中29例观察到MACCE,MACCE发生率18.5%。多因素分析结果显示,临床SYNTAX积分和SYNTAX积分均为MACCE的独立预测因子[临床SYNTAX积分,风险比(HR):2.07,95%可信区间(CI):1.25～3.44,P=0.005;SYNTAX积分,HR:1.86,95%CI:1.14～3.06,P=0.014]。受试者工作特征(ROC)曲线分析显示,SYNTAX积分曲线下面积(AUC)=0.667(95%CI:0.564～0.770,P=0.004),临床SYNTAX积分AUC=0.636(95%CI:0.519～0.753,P=0.020),两者均对MACCE有预测价值,加入了年龄肌酐射血分数(ACEF)积分的临床SYNTAX积分未能提高SYNTAX积分对MACCE的预测能力。结论临床SYNTAX积分和SYN-TAX积分均是预测复杂冠心病患者PCI预后的较理想工具,且临床SYNTAX积分并不优于SYNTAX积分。     

2型糖尿病长期治疗后合并冠心病及脑梗死的多因素分析

目的 研究2型糖尿病长期治疗后合并冠状动脉粥样硬化性心脏病(简称冠心病)、脑梗死病变的患病率及相关危险因素.方法 收集广西医科大学第二附属医院前后两次住院时间间隔4～12年的2型糖尿病患者185例.第一次住院185例为A组,前后两次住院时间间隔5年左右(4～7年)的85例为B组,前后两次住院时间间隔10年左右(8～12年)的100例为C组.收集所有研究对象前后两次住院的临床资料,包括血压、血糖、糖化血红蛋白(HBA1c)、血脂、心肌酶学、心电图、冠状动脉造影、头颅CT或MRI检查.比较冠心病及脑梗死的患病率,对冠心病及脑梗死与各危险因子做回归分析.结果 患者第一次住院与5～10年左右再次住院比较,收缩压(DBP)、空腹血糖(FBG)、餐后2h血糖(PBG2h)、总胆固醇(TC)、低密度脂蛋白胆固醇(LDL-C)均较第一次住院时有所下降,冠心病及脑梗死患病率随着病程延长而增高.10年左右后返回住院,冠心病患者中的脑梗死患病率比无冠心病患者中的脑梗死患病率显著增高(P＜0.05).分别以冠心病和脑梗死为因变量的Logistic回归分析显示,DBP和FBG是脑梗死的危险因素,年龄是冠心病的危险因素,HDL-C是冠心病的保护性因素.结论 2型糖尿病合并的冠心病和脑梗死患病率随着病程的延长而增高,治疗10年左右冠心病与脑梗死患病率呈现出显著相关性.     

Coronary stenting does not improve the long-term cardiovascular outcome of patients with mild to moderate renal insufficiency

Background Several studies have shown that coronary stenting reduces the frequency of clinical and angiographic restenosis in patients with mild to moderate renal insufficiency. However, less is known about the long-term benefits of stent use in this population. This study was aimed to determine the impact of coronary stenting on extended （5 years） long-term outcomes of patients with chronic renal insufficiency. Methods The study included 602 consecutive patients who underwent successful percutaneous coronary intervention with stenting. Renal insufficiency was defined as an estimated glomerular filtration rate 〈60 rrd.min-1-｜.73 m-2. The major adverse cardiac events were compared for patients with （n=160） and without （n=442） renal insufficiency. Results After the third year of follow-up, nonfatal myocardial infarction and revascularization rates were significantly increased in patients with renal insufficiency compared with those without renal dysfunction （16.9% vs 7.7%, P=0.001; 29.4% vs 15.8%, P 〈0.001）. In patients who had recurrent cardiovascular events, a significantly higher rate of de novo stenosis revascularization was found in patients with renal insufficiency than without renal insufficiency （57.7% vs 22.7%, P 〈0.001）, while there was no significant difference in target lesion revascularization between the groups （51.9% vs 43.6%, P=0.323）. Multivariate analysis demonstrated an independent impact of the presence of renal insufficiency on the major adverse cardiac events （hazard ratio： 1.488, 95% confidence interval： 1.051-2.106, P=0.025） and de novo stenosis （hazard ratio： 5.505, 95% confidence interval： 2.151-14.090, P 〈0.001）. Conclusions The late major adverse cardiac events, after successful coronary stenting, is increased in patients with an estimated glomerular filtration rate 〈60 ml.min-1.1.73m-2. This might be associated with increased risk of de novo stenosis in this population. Chin Med J 2009; 122（2）： 158-164     

Homocysteine and risk of cardiovascular disease among postmenopausal women.

CONTEXT: Individuals with elevated levels of homocysteine tend to have higher prevalence of cardiovascular disease. However, prospective studies of homocysteine are inconsistent and data among women are limited. OBJECTIVE: To determine whether elevated homocysteine levels in healthy postmenopausal women predict risk of developing cardiovascular disease. DESIGN: Prospective, nested case-control study with a mean 3-year follow-up. SETTING: The Women's Health Study, an ongoing US primary prevention trial initiated in 1993. PARTICIPANTS: From a total cohort of 28,263 postmenopausal women with no history of cardiovascular disease or cancer at baseline, 122 women who subsequently experienced cardiovascular events were defined as cases, and 244 age- and smoking status-matched women who remained free of disease during follow-up were defined as controls. MAIN OUTCOME MEASURES: Incidence of death due to cardiovascular disease, nonfatal myocardial infarction (MI), stroke, percutaneous transluminal coronary angioplasty, or coronary artery bypass graft by baseline homocysteine level. RESULTS: Of the 122 cases, there were 85 events of MI or stroke and 37 coronary revascularizations. Case subjects had significantly higher baseline homocysteine levels than controls (14.1 vs 12.4 micromol/L; P = .02). Subjects with homocysteine levels in the highest quartile had a 2-fold increase in risk of any cardiovascular event (relative risk [RR], 2.0; 95% confidence interval [CI], 1.1-3.8). This effect was largely due to an excess of cases with high levels of homocysteine; the RR for those with homocysteine levels at or higher than the 95th percentile (20.7 micromol/L) was 2.6 (95% CI, 1.1-5.7). Risk estimates were independent of traditional risk factors and were greatest for the end points of MI and stroke (RR for those with baseline homocysteine levels in the top quartile, 2.2; 95% CI, 1.1-4.6). Self-reported multivitamin supplement use at study entry was associated with significantly reduced levels of homocysteine (P<.001). However, the association between increasing quartile of homocysteine level and risk of MI or stroke remained significant in analyses controlling for baseline multivitamin supplement use (P = .003 for trend), and subgroup analyses limited to women who were (P = .02 for trend) or were not (P = .04 for trend) taking multivitamin supplements. CONCLUSIONS: Among healthy postmenopausal US women, elevated levels of homocysteine moderately increased the risk of future cardiovascular disease. Whether lowering the homocysteine level reduces risk of cardiovascular events requires testing in randomized controlled trials.     

A prospective study of egg consumption and risk of cardiovascular disease in men and women

CONTEXT: Reduction in egg consumption has been widely recommended to lower blood cholesterol levels and prevent coronary heart disease (CHD). Epidemiologic studies on egg consumption and risk of CHD are sparse. OBJECTIVE: To examine the association between egg consumption and risk of CHD and stroke in men and women. DESIGN AND SETTING: Two prospective cohort studies, the Health Professionals Follow-up Study (1986-1994) and the Nurses' Health Study (1980-1994). PARTICIPANTS: A total of 37851 men aged 40 to 75 years at study outset and 80082 women aged 34 to 59 years at study outset, free of cardiovascular disease, diabetes, hypercholesterolemia, or cancer. MAIN OUTCOME MEASURES: Incident nonfatal myocardial infarction, fatal CHD, and stroke corresponding to daily egg consumption as determined by a food-frequency questionnaire. RESULTS: We documented 866 incident cases of CHD and 258 incident cases of stroke in men during 8 years of follow-up and 939 incident cases of CHD and 563 incident cases of stroke in women during 14 years of follow-up. After adjustment for age, smoking, and other potential CHD risk factors, we found no evidence of an overall significant association between egg consumption and risk of CHD or stroke in either men or women. The relative risks (RRs) of CHD across categories of intake were less than 1 per week (1.0), 1 per week (1.06), 2 to 4 per week (1.12), 5 to 6 per week (0.90), and > or =1 per day (1.08) (P for trend = .75) for men; and less than 1 per week (1.0), 1 per week (0.82), 2 to 4 per week (0.99), 5 to 6 per week (0.95), and > or =1 per day (0.82) (P for trend = .95) for women. In subgroup analyses, higher egg consumption appeared to be associated with increased risk of CHD only among diabetic subjects (RR of CHD comparing more than 1 egg per day with less than 1 egg per week among diabetic men, 2.02 [95% confidence interval, 1.05-3.87; P for trend = .04], and among diabetic women, 1.49 [0.88-2.52; P for trend = .008]). CONCLUSIONS: These findings suggest that consumption of up to 1 egg per day is unlikely to have substantial overall impact on the risk of CHD or stroke among healthy men and women. The apparent increased risk of CHD associated with higher egg consumption among diabetic participants warrants further research.

目的：探讨冠心病合并微量清蛋白尿(MAU)与心血管事件的相关性。方法连续选择该院冠心病患者共120例,根据尿清蛋白肌酐比值(UACR)分为观察组(30 mg/g< UACR<300 mg/g,n=80)和对照组(UACR≤30 mg/g,n=40),随访15个月后比较分析两组患者心血管事件与 MAU 水平的相关性。结果观察组的 MAU 水平显著高于对照组,差异有统计学意义(P <0.05)。观察组患者的心血管事件共发生163次,对照组57次,观察组的心血管事件发生率显著高于对照组,差异有统计学意义(t=3.717,P <0.05)。Spearman 相关分析可知,MAU 与心血管事件呈显著正相关(r =0.721,P <0.01)。影响因素有MAU(P =0.001)、C 反应蛋白(P =0.037)。结论MAU 浓度与冠心病患者心血管事件密切相关,可以预测心血管事件的发生。     

Long-term cardiac prognosis following noncardiac surgery. The Study of Perioperative Ischemia Research Group.

OBJECTIVE--To determine the long-term (2-year) cardiac prognosis of high-risk patients undergoing noncardiac surgery and to determine the predictors of long-term adverse cardiac outcome. DESIGN--Prospective cohort study. Historical, clinical, and laboratory data were collected during the in-hospital period, and at 6 months, 1 year, and 2 years following surgery. Data were analyzed using proportional hazards models. SETTING--University-affiliated Veterans Affairs medical center. POPULATION--A consecutive sample of 444 patients with or at high risk for coronary artery disease who had undergone elective noncardiac surgery and were discharged from the hospital in stable condition. MAIN OUTCOME MEASURES--Cardiac death, myocardial infarction, unstable angina, progressive angina requiring coronary artery bypass graft surgery or coronary angioplasty, and new unstable angina requiring hospitalization. RESULTS--Forty-seven patients (11%) had major cardiovascular complications during a 728-day (median) follow-up period: 24 had cardiac death; 11, nonfatal myocardial infarction; six, progressive angina requiring coronary artery bypass graft surgery or coronary angioplasty; and six, new unstable angina requiring hospitalization. Thirty percent of outcomes occurred within 6 months of surgery and 64% within 1 year. Five independent predictors of long-term outcome were identified. Three predictors reflected the preexisting chronic disease state: (1) the presence of known vascular disease (hazard ratio, 6.1; 95% confidence interval [CI], 2.5 to 15.0; P less than .0001); (2) a history of congestive heart failure (hazard ratio, 5.0; 95% CI, 2.0 to 12.0; P less than .0005); and (3) known coronary artery disease (hazard ratio, 3.7; 95% CI, 1.7 to 8.0; P less than .0007). Two predictors reflected acute postoperative ischemic events: (1) myocardial infarction/unstable angina (hazard ratio, 20; 95% CI, 7.5 to 53.0; P less than .0001) and (2) myocardial ischemia (hazard ratio, 2.2; 95% CI, 1.1 to 4.3; P less than .03). Patients surviving a postoperative in-hospital myocardial infarction had a 28-fold increase in the rate of subsequent cardiac complications within 6 months following surgery, a 15-fold increase within 1 year, and a 14-fold increase within 2 years (95% CI, 5.8 to 32; P less than .00001). Seventy percent of all long-term adverse outcomes were preceded by in-hospital postoperative ischemia that occurred at least 30 days (median, 282 days) before the long-term event. The development of congestive heart failure or ventricular tachycardia (without ischemia) during hospitalization was not associated with adverse long-term outcome. CONCLUSIONS--The incidence of long-term adverse cardiac outcomes following noncardiac surgery is substantial. At increased risk are patients with chronic cardiovascular disease; at highest risk are patients with acute perioperative ischemic events. We conclude that survivors of in-hospital perioperative ischemic events, specifically myocardial infarction, unstable angina, and postoperative ischemia, warrant more aggressive long-term follow-up and treatment than is currently practiced.     

Impact of depressed left ventricular function on outcomes in patients with three-vessel coronary disease undergoing percutaneous coronary intervention

Background  Patients with multivessel coronary artery disease and depressed left ventricular ejection fraction (LVEF) represent a high risk group of patients for coronary revascularization. There are limited data on percutaneous coronary intervention treatment in this population.  

Methods  Among a cohort of 4335 patients with three-vessel disease with or without left main disease undergoing percutaneous coronary intervention, 191 patients had LVEF <40% (low ejection fraction (EF)) and 4144 patients had LVEF ≥40%. In-hospital and long-term outcomes were examined according to LVEF.

Results  The estimated two-year rates of major adverse cardiac events, cardiac death, and myocardial infarction were significantly higher in the low EF group (19.64% vs. 8.73%, Log-rank test: P <0.01; 10.30% vs. 1.33%, Log-rank test: P <0.01, and 10.32% vs. 2.28%, Log-rank test: P <0.01 respectively), but there was no difference in the rates of target vessel revascularization (6.18% vs. 6.11%, Log-rank test: P=0.96). Using the Cox proportional hazard models, LVEF <40% was a significant risk factor for cardiac death, myocardial infarction, and major adverse cardiac events (OR (95% CI): 4.779 (2.369–9.637), 2.673 (1.353–5.282), and 1.827 (1.187–2.813) respectively), but was not a statistically significant risk factor for target vessel revascularization (OR (95% CI): 1.094 (0.558–2.147)).

Conclusion  Among patients undergoing percutaneous coronary intervention for multivessel coronary artery disease, left ventricular dysfunction remains associated with further risk of cardiac death in-hospital and during long-term follow-up.

Comparison of drug eluting stent implantation with coronary artery bypass surgery in the treatment of patients with chronic total occlusion and multiple vessel disease

Background  In patients with chronic total occlusion (CTO) and multivessel coronary artery disease, the comparison of surgical and the percutaneous revascularization strategies has rarely been conducted. The aim of this study was to compare long term clinical outcomes of drug eluting stent (DES) implantation with coronary artery bypass surgery (CABG) in the patients with CTO and multivessel disease.

Methods  From a prospective registry of 6000 patients in our institution, we included patients with CTO and multivessel coronary artery disease who underwent either CABG (n=679) or DES (n=267) treatment. Their propensity risk score was used for adjusting baseline differences.

Results  At a median follow-up of three years, propensity score adjusted Cox regression analysis showed that the rate of major adverse cardiac cerebrovascular events (MACCE) was lower in CABG group (12.7% vs. 24.3%, hazard ratio (HR) 1.969, 95% CI 1.219–3.179, P=0.006) mainly due to lower rate of target vessel revascularization in CABG group than in DES group (3.1% vs. 17.2%, HR 16.14, 95% CI 5.739–45.391, P <0.001). The incidence of cardiac death or myocardial infarction (composite end point) was not significantly different between these two groups. On multivariate analysis, the significant predictors of MACCE were only the type of revascularization. Age, left ventricular ejection fraction (LVEF), and complete revascularization were identified as significant predictors of composite end points.

Conclusions  Our study shows that in patients with CTO and multivessel coronary disease, DES can offer comparable long term outcomes in cardiac death and myocardial infraction free survival in comparison with CABG. However, there is an increased rate of MACCE which results from more repeat revascularizations. Obtaining a complete revascularization is crucial for decreasing adverse cardiac events.

     

Prognostic importance of social and economic resources among medically treated patients with angiographically documented coronary artery disease.

OBJECTIVE--To evaluate the hypothesis that diminished social and economic resources impact adversely on cardiovascular mortality in patients with coronary artery disease. DESIGN--Inception cohort study of patients undergoing cardiac catheterization from 1974 through 1980 and followed up through 1989. SETTING--Tertiary care university medical center. PATIENTS--Consecutive sample of 1965 medically treated patients with stenosis 75% or greater of at least one major coronary artery. Five hundred patients were not enrolled due to logistic problems; 33 refused; 64 had missing data on key medical variables. The final study population included 1368 patients, 82% male, with a median age of 52 years. MAIN OUTCOME MEASURE--Survival time until cardiovascular death. RESULTS--Independent of all known baseline invasive and noninvasive medical prognostic factors, patients with annual household incomes of $40,000 or more had an unadjusted 5-year survival of 0.91, compared with 0.76 in patients with incomes of $10,000 or less (Cox model adjusted hazard ratio, 1.9; 95% confidence interval, 1.57 to 2.32; P = .002). Similarly, unmarried patients without a confidant had an unadjusted 5-year survival rate of 0.50, compared with 0.82 in patients who were married, had a confidant, or both (adjusted hazard ratio, 3.34; 95% confidence interval, 1.84 to 6.20; P less than .0001). CONCLUSIONS--Low levels of social and economic resources identify an important high-risk group among medically treated patients with coronary artery disease, independent of important medical prognostic factors. Additional study will be required to see if interventions to increase these resources improve prognosis.     

颈动脉内中膜厚度及尿微量白蛋白在多动脉粥样硬化患者心血管危险评估中的作用

目的探讨颈动脉内中膜厚度(carotid intima-media thickness,CIMT)及尿微量白蛋白(microalbuminuria,MA)与动脉粥样硬化患者的病情程度及心血管事件发生率之间的关系。方法选择发生在多个区域中,动脉狭窄≥50%,已施行血运重建操作的患者149例为试验组;同时选择40例动脉粥样硬化性狭窄<50%的患者作为对照,分别测定IMT和MA。结果 CIMT≥1.38 mm时,对≥3个区域动脉狭窄的敏感性和特异性分别为90.0%和82.6%。MA≥6.85 mg/dl时,对≥2个区域动脉狭窄的敏感性和特异性分别为54.9%和83.3%。试验组发生心血管事件104例。CIMT第1、2、3、4四分位数Kaplan-Meier两年无心血管事件存活率分别为93.9%、95.7%、73.9%和59.6%;MA第1、2、3、4四分位数Kaplan-Meier两年无心血管事件存活率分别为95.7%、89.6%、72.3%和66.0%。独立的心血管不良事件预测因子在多变量Cox比例风险模型中为:CIMT≥1.38 mm,RR=1.83;CI=1.049~3.196(P<0.001),MA≥6.85 mg/dl,RR=0.99;CI=0.576~1.703(P<0.001)。把CIMT引入模型分层显著提高了心血管事件危险的预测(_chi2=7.098,P<0.01),把MA引入模型分层对心血管事件危险预测影响不显著(_chi2=0.002,P<0.01)。结论经过血运重建操作的患者,测量颈动脉内中膜厚度对未来心血管危险分层有重要且独立的贡献,CIMT≥1.38 mm与1.8倍有害心血管事件有关,而尿MA≥6.85 mg/dl与近1倍有害心血管事件有关。
