血尿酸与冠心病的相关分析

目的分析血清尿酸水平是否与冠心病相关。方法经冠状动脉造影确诊的冠心病患者142例和非冠心病患者92例。分别测定血清尿酸及血脂水平,同时记录性别、年龄、吸烟、高血压、糖尿病等相关因素。结果冠心病患者血清尿酸水平显著高于对照组（P<0.01）,相关分析显示血清尿酸水平与冠脉狭窄指数、年龄、高血压、糖尿病、高密度脂蛋白、胆固醇（P<0.05或P<0.01）呈正相关。多因素回归分析显示,血清尿酸与冠心病的发生和冠脉狭窄指数无明显相关。结论高尿酸血症不是冠心病的独立危险因素。     

血尿酸、血清同型半胱氨酸与冠状动脉病变程度的关系分析

目的探讨血尿酸、血清同型半胱氨酸水平与冠心病患者冠脉病变严重程度的关系。方法回顾性分析2018年11月至2019年11月于我院住院的90例冠心病患者作为试验组,纳入同时期性别、年龄相匹配的冠脉造影正常的患者50例作为对照组。根据SYNTAX评分对冠状动脉严重程度进行评分,根据结果分为低危组(<22分)、中危组(23~32分)及高危组(>33分)。记录患者一般临床资料,抽取清晨空腹血化验UA、Hcy、TC、TG、HDL-C、LDL-C,并行冠脉造影检查,比较分析各组患者血脂、UA、Hcy的差异,并进行相关性分析及Logistic回归分析。结果SYNTAX评分中危组、高危组与对照组相比较,TC、LDL-C、UA、HCy升高,差异有统计学意义(P<0.05);UA与SYNTAX评分呈正相关(r=0.487,P<0.05),Hcy与SYNTAX评分呈正相关(r=0.437,P<0.05);Logstic回归分析发现LDL-C、UA、Hcy是冠心病患者冠状动脉病变程度的独立危险因素(P<0.05)。结论血尿酸、血清同型半胱氨酸水平是冠心病患者冠状动脉病变严重程度的危险因素,且血尿酸、血清同型半胱氨酸水平越高,冠脉病变越严重。

Association of uric acid with mortality in patients with stable coronary artery disease

ObjectiveThe association between uric acid and cardiovascular disease is poorly studied. We undertook this study to assess whether uric acid level predicts clinical outcome in patients with stable coronary artery disease (CAD) treated with percutaneous coronary intervention (PCI).Materials/MethodsThis study included 8149 patients with stable CAD who underwent PCI. Uric acid was measured before angiography. The primary end point was 1-year mortality. Quartiles of quartiles of uric acid were: 1.49 to < 5.49 mg/dl (1st quartile; n=2032 patients), 5.49 to < 6.40 mg/dl (2nd quartile; n=1981 patients), 6.40 to < 7.50 mg/dl (3rd quartile; n=2093 patients) and 7.50 to 21.90 mg/dl (4th quartile; n=2043 patients).ResultsThere were 196 deaths during the 1-year follow-up. The numbers of deaths (Kaplan-Meier estimates) according to uric acid quartiles were: 35 deaths (1.8%) in the 1st quartile, 30 deaths (1.6%) in the 2nd quartile, 45 deaths (2.2%) in the 3rd quartile and 86 deaths (4.3%) in the 4th quartile (unadjusted hazard ratio [HR]=1.60, 95% confidence interval [CI] 1.38-1.86, P < 0.001 for each standard deviation [SD] increase in the logarithmic scale). After adjustment for traditional cardiovascular risk factors, renal function and inflammatory status, the association between uric acid and 1-year mortality remained significant (adjusted HR=1.26, 95% CI 1.07-1.48; P=0.005 for each standard deviation increase in the logarithmic scale). Uric acid improved predictivity of the multivariable model regarding mortality (P=0.040).ConclusionsElevated level of uric acid is an independent predictor of 1-year mortality in patients with stable CAD treated with PCI.     

Association between early graft patency and late outcome for patients undergoing artery bypass graft surgery

For a group of 658 patients who received coronary artery bypass graft surgery, we investigated the correlation between the degree of early (6 months) graft patency and recurrence of anginal symptoms, late myocardial infarction, and postoperative coronary-related death. The patients were grouped according to the number of surgically placed grafts, and each group was further subgrouped on the basis of the number of grafts functioning at the early postsurgical follow-up examination. The patients were observed over a period as long as 13 years. The frequency with which angina returned correlated significantly with the degree of patency within each of the groups (one, two, three, or four grafts); patients with a higher percentage of patent grafts experienced longer periods of freedom from angina. On the average, patients with all of their multiple grafts patent experienced at least 7 more years of symptomatic relief than their counterparts with all grafts occluded. Most surprisingly, the rate of the return of angina for those patients who had all grafts patent and were completely revascularized was independent of the number of diseased vessels or the number of grafts placed. The findings for coronary death and postoperative infarction showed similar trends.     

Association between plasma ceramides and inducible myocardial ischemia in patients with established or suspected coronary artery disease undergoing myocardial perfusion scintigraphy

BackgroundRecent studies have suggested that specific plasma ceramides are independently associated with major adverse cardiovascular events in patients with coronary artery disease (CAD), but it is currently unknown whether plasma ceramide levels are associated with stress-induced reversible myocardial ischemia.MethodsWe measured six previously identified high-risk plasma ceramide molecules [Cer(d18:1/16:0), Cer(d18:1/18:0), Cer(d18:1/20:0), Cer(d18:1/22:0), Cer(d18:1/24:0), and Cer(d18:1/24:1)] in 167 consecutive patients with established or suspected CAD who underwent either exercise or dypiridamole myocardial perfusion scintigraphy (MPS) for various clinical indications. Plasma ceramide levels were measured by a targeted liquid chromatography-tandem mass spectrometry assay both at baseline and after MPS.ResultsSeventy-eight patients had inducible myocardial ischemia on stress MPS. Women had significantly higher circulating levels of basal and post-stress Cer(d18:1/16:0) and Cer(d18:1/18:0) compared to men, whereas all other plasma ceramides did not differ between the sexes. Of the six measured plasma ceramides, basal Cer(d18:1/24:1) showed the strongest association with the presence of stress-induced myocardial perfusion defects in univariate analysis (unadjusted-odds ratio 1.48 per 1-SD increment, 95% confidence interval 1.08–2.04). Notably, after adjustment for age, sex, smoking, dyslipidemia, hypertension, diabetes, prior history of CAD, left ventricular ejection fraction, and type of stress testing (exercise vs. dypiridamole), all measured ceramides, except for plasma Cer(d18:1/24:0), were independently associated with the presence of inducible myocardial ischemia.ConclusionsDistinct plasma ceramides are positive and independent predictors of stress-induced myocardial perfusion defects in patients with established or suspected CAD referred for clinically indicated MPS. Further research is needed to examine whether distinct plasma ceramides could be a useful therapeutic target for treatment and management of CAD.     

血清尿酸水平与冠心病患者冠脉狭窄程度的关系

目的：探讨冠心病患者血清尿酸(UA)水平和冠脉狭窄程度的关系。方法：166例患者纳入研究,其中经冠脉造影诊断为冠心病119例,非冠心病患者47例。纳入患者均行生化检测,同时彩超评价患者心功能。结果：与对照组相比,冠心病患者血清UA水平显著升高(P<0.01)；与UA正常组相比,UA升高组患者冠状动脉病变支数增加(P<0.01),冠脉狭窄计分CASS升高(P<0.01),而心功能明显减低(P<0.01)。血清UA水平与冠脉狭窄计分CASS呈正相关(r=0.334, p<0.01),而与心功能呈负相关(r=?0.252, p< 0.01)。结论：冠心病患者血清UA水平与冠脉狭窄程度密切相关。     

Association of serum uric acid with cardiovascular disease in rheumatoid arthritis

OBJECTIVES: Elevated serum uric acid (SUA) levels have been associated with cardiovascular disease (CVD) in the general population. Rheumatoid arthritis (RA) is not thought to associate with high SUA but is characterized by increased CVD morbidity and mortality. We aimed to explore a potential association of SUA with CVD in RA patients and to evaluate whether such an association is present when the traditional CVD risk factors are taken into account. METHODS:. 400 consecutive RA patients were recruited in this cross-sectional study and had all traditional CVD risk factors and SUA assessed. The association of SUA levels with other variables was assessed using bivariate correlations. Subsequent binary logistic models with appropriate adjustments were used to test the independence of the association between SUA and CVD. RESULTS: SUA levels were significantly higher in RA patients with CVD (RA + CVD) compared with RA patients without CVD (RA - CVD) (5.68 +/- 1.81 mg dl(-1) vs 5.06 +/- 1.41 mg dl(-1), P = 0.001). After adjusting for CVD risk factors, physical function (health assessment questionnaire, HAQ) and use of diuretics and/or statins the association between SUA and CVD in RA patients remained significant [Odds ratio (OR) = 1.36, 95% confidence interval (CI) 1.04-1.79, P = 0.025]. Compared with subjects with SUA levels in the lowest quintile (<3.86 mg dl(-1)), those within the highest quintile (>/=6.38 mg dl(-1)) had a 6-fold increase in the odds of having CVD (adjusted OR 6.46, 95% CI 1.66-25.05, P = 0.007). CONCLUSIONS: This cross-sectional study suggests that SUA may be independently associated with CVD in RA patients. This needs to be confirmed in prospective studies.     

血尿酸水平与冠脉狭窄及冠心病的关系

目的探讨血尿酸（SUA）水平与冠脉狭窄和冠心病（CHD）的关系。方法选择647例行冠脉造影患者,根据其冠脉有无狭窄分为冠脉正常组和非正常组,以冠脉至少有1支狭窄≥50%分为CHD组与非CHD组。检测患者的血脂及SUA。结果在冠脉狭窄和CHD两个分组标准下,男性不同年龄组间的SUA水平无统计学差异,女性有统计学差异（P〈0.01）。男性SUA水平与冠脉狭窄或CHD发生均无相关性;女性SUA水平与CHD发生虽无统计学差异,但与冠脉狭窄发生有关（P〈0.05）,对传统风险因素校正后,多因素分析显示女性SUA水平与冠脉狭窄无统计学意义（P〉0.05）。结论 SUA存在性别差异,女性高尿酸血症与CHD发生有一定关系,与冠脉狭窄密切相关,但非发生冠脉狭窄的独立危险因素。男性SUA水平与二者均无关。     

Sialic acid or troponin T to detect perioperative myocardial damage in patients undergoing elective coronary artery bypass grafting.

Sialic acid (SA), a family of acetylated derivatives of neuraminic acid, is elevated in patients with coronary heart disease. Cardiac troponin T (cTnT), myoglobin (Mb), and creatine kinase-MB (CK-MB) are specific markers of myocardial injury and are, at present, widely used to detect perioperative myocardial damage during coronary artery bypass grafting (CABG) surgery. The present study investigated the net myocardial release of SA and the cardiac markers (cTnT, Mb, CK-MB) during reperfusion after hypothermic cardioplegic cardiac arrest in 25 patients undergoing elective CABG. Additional paired arterial, central venous, and coronary sinus blood samples were obtained after atrial cannulation before aortic cross-clamping (preischemic sample) and at 1 and 10 min after aortic declamping (reperfusion samples). There were no increase in the SA, cTnT, Mb and CK-MB concentrations before aortic cross-clamping, but there was considerable release of these markers within 10 min after aortic declamping: cTnT release was significantly higher compared with baseline values before aortic cross-clamping. In contrast to SA, Mb, and CK-MB, the difference between baseline and release values for cTnT at 1 min after aortic declamping was not significant. The rate of increase for SA was significantly higher than for Mb, CK-MB and cTnT. SA is a unique and novel marker that could be particularly useful in assessing myocardial cell damage in patients undergoing cardiac surgery.     

冠心病合并2型糖尿病患者置入药物洗脱支架的疗效评价

目的 评价冠心病合并2型糖尿病患者冠状动脉病变置入药物洗脱支架后的疗效。方法 选择我院2004年4月至2005年8月连续接受置入药物洗脱支架（DES）或金属裸支架（BMS）治疗并且进行了冠状动脉造影随访的139例的冠心病合并2型糖尿病患者。所有患者在支架术后6个月后接受冠状动脉造影随访。结果共139例患者（男性114例,女性25例）221处病变完成随访。其中C型病变94处（42．5％）,完全闭塞病变42处（19．0％）,平均每个病变支架长度（26．53±14．72）mm,平均参考血管直径（2．80±0．43）mm。两组患者在性别比例和年龄方面差异无统计学意义。两组在冠心病的危险因素如：高血压病、高脂血症、吸烟等方面差异无统计学意义。两组病变的复杂程度基本相当。DES组的参考血管直径比BMS组小[（2．71±0．41）mm比（2．98±0．53）mm,P〈0．001]。6个月后随访,DES组的支架内再狭窄率（10．6％比38．6％,P〈0．001）和病变内晚期腔径丢失[（0．24±0．56）mm比（0．91±0．77）mm,P〈0．001]明显低于BMS组。DES组的靶病变血管重建率显著低于BMS组（8．6％比30．0％,P〈0．001）。DES组有4例晚期支架内血栓。结论 本研究显示药物洗脱支架对于冠心病合并2型糖尿病患者冠状动脉病变的介入治疗有着良好的治疗效果,明显优于金属裸支架。     

Effect of perioperative myocardial infarction on late survival in patients undergoing coronary artery bypass surgery

From the Seattle Heart Watch angiography registry, the baseline characteristics and late survival of 77 patients who sustained operative infarction (new Q waves) with myocardial revascularization were compared with 1790 patients who underwent coronary artery bypass without perioperative infarction. With the exception of coronary collateral vessels, which were less frequently seen in the patients with perioperative infarction, no baseline or operative characteristic distinguished between the two groups. Late survival was clearly adversely affected by perioperative infarction. Five-year survival was 76% in patients with perioperative infarction, compared with 90% in those with no perioperative infarction.     

Multimarker risk stratification approach and cardiovascular outcomes in patients with stable coronary artery disease undergoing elective percutaneous coronary intervention

AimsWe studied the utility of multimarker risk stratification approach to predict cardiovascular outcomes in patients with stable coronary artery disease, undergoing elective percutaneous coronary intervention (PCI).MethodsWe prospectively evaluated 302 consecutive patients with stable coronary artery disease and normal CPK-MB and cardiac troponin T levels, and who underwent elective PCI at our institution. The following cardiac biomarkers were measured before and between 12 and 24 h post-procedure: CK-MB, cardiac troponin T, hs-CRP, and NT-ProBNP. Patients were followed up for a minimum of 6 months.ResultsPost-PCI, CPK-MB levels were elevated but below myocardial infarction (MI) range in 70 patients (23%), and in the MI range in 6 patients (2%). Troponin T levels were detectable but below the 99th percentile (microleak) in 32 patients (10.6%) and elevated above the 99th percentile (periprocedural MI) in 104 patients (34.4%). At 9 months’ follow-up, 1% died, 2% had stable angina, 10.3% had non-fatal MI, and 87.7% remained asymptomatic. There was no significant difference in clinical events among groups stratified by elevation of one biomarker or multiple biomarkers.ConclusionSingle or multiple biomarker strategy in patients with normal baseline biomarkers failed to predict major cardiac events after PCI over medium-term follow-up.     

老年疑诊冠心病患者冠心病的危险因素以及冠状动脉病变程度的相关因素

目的 探讨老年（≥60岁）疑诊冠心病患者的冠心病危险因素及其冠状动脉病变严重程度的相关因素。方法 选择我中心首次行诊断性冠状动脉造影（CAG）的老年疑诊冠心病患者4732例。根据CAG结果分为冠心病组（3539例）和非冠心病组（1193例）。冠状动脉病变程度特点用Gensini积分和主要血管受累支数进行评价。采用多元线性回归和logistic回归进行数据分析。结果 ①多元线性回归分析表明Gensini积分与患者年龄、男性、高血压病、高脂血症、糖尿病、慢性肾脏病及空腹血糖水平呈独立正相关,与血清总胆红素呈独立负相关。②多元线性回归分析表明病变支数与患者年龄、吸烟、男性、高血压病、高脂血症、糖尿病、慢性肾脏病、脑血管病及空腹血糖水平呈独立正相关,与血清总胆红素呈独立负相关。③二分类多因素Logistic分析显示,糖尿病是冠状动脉造影诊断冠心病最显著的独立相关危险因素（OR=2.591,95% CI:1.942-3.458,P<0.01）,其他危险因素依次为男性、高血压病、吸烟、慢性肾脏病、高脂血症和年龄,总胆红素为其独立保护因素（OR=0.960, 95% CI:0.941-0.979,P<0.01）。结论 糖尿病是现阶段老年住院疑诊冠心病患者冠状动脉造影诊断冠心病最显著的独立相关危险因素,总胆红素水平为其独立相关保护因素。     

Anemia as an independent predictor of perioperative and long-term cardiovascular outcome in patients scheduled for elective vascular surgery

Anemia is common in patients scheduled for vascular surgery and is a risk factor for adverse cardiac outcome. However, it is unclear whether this is an independent risk factor or an expression of underlying co-morbidities. In total, 1,211 patients (77% men, 68 +/- 11 years of age) were enrolled. Anemia was defined as serum hemoglobin levels <13 g/dl for men and <12 g/dl for women and was divided into tertiles to compare mild (men 12.2 to 13.0, women 11.2 to 12.0), moderate (men 11.0 to 12.1, women 10.2 to 11.1), and severe (men 7.2 to 11.0, women 7.5 to 10.1) anemia with nonanemia. Outcome measurements were 30-day and 5-year major adverse cardiac events (MACEs; cardiac death or myocardial infarction). All risk factors were noted. Multivariable logistic and Cox regression analyses were used, adjusting for all cardiac risk factors, including heart failure and renal disease. Data are presented as hazard ratios with 95% confidence intervals. In total, 74 patients (6%) had 30-day MACEs and 199 (17%) had 5-year MACEs. Anemia was present in 399 patients (33%), 133 of whom had mild anemia, 133 had moderate anemia, and 133 had severe anemia. Presence of anemia was associated with renal dysfunction, diabetes, and heart failure. After adjustment for all clinical risk factors, 30-day hazard ratios for a MACE per anemia group were 1.8 for mild (0.8 to 4.1), 2.3 for moderate (1.1 to 5.4), and 4.7 for severe (2.6 to 10.9) anemia, and 5-year hazard ratios for MACE per anemia group were 2.4 for mild (1.5 to 4.2), 3.6 for moderate (2.4 to 5.6), and 6.1 for severe (4.1 to 9.1) anemia. In conclusion, the presence and severity of preoperative anemia in vascular patients are significant predictors of 30-day and 5-year cardiac events, regardless of underlying heart failure or renal disease.     

Association between serum uric acid levels and cardiovascular events in hospitalized patients with type 2 diabetes

AimsThis study aimed to determine the association between serum uric acid (UA) levels and cardiovascular events in hospitalized patients with type 2 diabetes mellitus (T2DM).MethodsA retrospective cohort study was conducted in 2227 hospitalized patients with T2DM. Cox proportional hazards regression was used to assess the association between serum UA and cardiovascular events, including cardiovascular death, non-fatal myocardial infarction, non-fatal stroke, heart failure, unstable angina, and arrhythmias requiring hospitalization.ResultsAmong 1314 men, 143 (10.9%) experienced cardiovascular events. Serum UA level was not associated with the risk of cardiovascular events (hazard ratio [HR] per 100 μmol/L increase in serum UA: 1.12, 95% confidence interval [CI]: 0.90–1.40). Among 913 women, 96 (10.5%) experienced cardiovascular events. For every 100 μmol/L increase in serum UA level, the risk of experiencing a cardiovascular event increased by 27% (HR: 1.27, 95% CI: 1.02–1.57).ConclusionsIn hospitalized patients with T2DM, baseline serum UA levels were positively associated with cardiovascular events in women, but not in men. Serum UA levels may be a significant independent risk factor for cardiovascular events in women with T2DM.     

血尿酸水平与冠状动脉病变及代谢综合征的关系

目的 探讨血尿酸水平变化与冠状动脉病变程度、代谢综合征及其相关组分的关系.方法 343例(男性223例,女性120例)接受冠状动脉造影检查的患者,应用冠脉狭窄指数(CSI)评价冠状动脉病变严重程度.结果 (1)女性血尿酸水平显著低于男性[(306.3±76.9对358.9±85.2)μmol/L,P＜0.01],而男女性代谢综合征及各组分的患病率未见明显差异.(2)女性≥3项代谢异常亚组血清尿酸水平显著高于1项代谢异常亚组(P＜0.01)及2项代谢异常亚组(P＜0.05),而男性尿酸水平与代谢异常数目无明显关系.(3)将男、女人群的尿酸值分为4分位数,女性位于上1/4位点者的CSI评分高于下1/4位点者[7.0(2.5～12.0)对2.0(0.0～6.0),P=0.025].女性多支病变组血尿酸水平明显高于无病变组[(327.0±81.9对284.9±78.6)μmol/L,P=0.033].(4)Logistic回归显示年龄(β=0.042,P=0.007)和血脂异常(β=0.836,P=0.037)为男性冠脉病变的独立危险因素,而女性人群中血压异常(β=1.127,P=0.039)及血脂异常(β=0.901,P=0.009)为影响冠脉病变的主要因素.结论 血尿酸水平较高的女性,代谢异常组分聚集较多,其冠状动脉病变程度较重,故尿酸水平可作为女性动脉粥样硬化的标志.

Abstract：

Objective To analyze the association of blood uric acid level with the severity of coronary artery stenotic changes, metabolic syndrome (MS), and its components. Methods A total of 343 individuals ( male 223,female 120) who underwent coronary angiography and had complete data on MS and serum uric acid were collected. The severity of coronary artery disease (CAD) was assessed by the coronary stenesis index (CSI). MS was diagnosed according to the Guideline on Prevention and Treatment of Blood Lipid Abnormality in Chinese Adults. Results (1)The mean uric acid level was significantly lower in women than in men [ ( 306.3±76.9 vs 358.9±85.2 ) μmol/L, P＜0.01 ]. The prevalence of MS and its components showed no difference between men and women. (2) The uric acid level in women with 3 components was higher than those with1( P＜0. 01 ) or 2 ( P＜0.05 ) components of metabolic disorders, but not in men. (3) Quartiles of concentration of uric acid were computed. Compared with those in the lowest quartile of uric acid, women in the highest quartile had higher CSI score [ 7.0 (2.5-12.0) vs 2. 0( 0.0-6.0), P= 0. 025 ]. Moreover, the uric acid level was higher in women with multivessel lesions than nonCAD patients [ (327.0±81.9 vs 284.9±78.6) μmol/L, P = 0.033 ]. However, no correlation was found between uric acid level and the severity of coronary artery lesion in men. (4) Logistic regression showed that age (β=0.042, P=0. 007) and dyslipidemia(β=0.836, P=0. 037 ) were the independent risk factors of CAD in men, and hypertension(β=1. 127, P=0.039) and dyslipidemia(β=0.901, P=0.009)in women. Conclusions In women with higher uric acid level, the clustering of metabolic abnormalities was increased, and the coronary artery lesion was more severe. High uric acid level might be a marker of CAD for women.
