目的探讨急性冠状动脉综合征(ACS)患者血浆B型脑钠肽(BNP)水平及全球急性冠状动脉事件注册(GRACE)危险评分对冠状动脉病变的预测关系。方法 ACS患者317例,其中急性心肌梗死患者68例,不稳定性心绞痛患者249例,所有患者均行冠状动脉造影,测定血浆BNP水平,并进行GRACE危险评分,分析不同组别患者冠状动脉病变的特点、血浆BNP水平及GRACE危险评分与冠状动脉病变的关系。结果 GRACE危险评分低、中、高危患者在冠状动脉病变支数和冠状动脉狭窄程度上差异具有统计学意义(P<0.01或P<0.05)。GRACE危险评分高危组患者血浆BNP水平明显高于中、低危组(P<0.01)。GRACE危险评分与血浆BNP水平呈正相关(r=0.26,P<0.01)。结论 GRACE危险评分和血浆BNP水平对ACS患者冠状动脉病变支数、狭窄程度有一定的预测价值。 相似文献

Background Many patients with acute coronary syndrome (ACS) develop recurrent angina (RA) during hospitalization. The aim of this non-randomized, prospective study was to investigate the predictive factors of RA in unselected patients with ACS enrolled in the global registry acute coronary events (GRACE) during hospitalization in China.Methods Between March 2001 and October 2004., enrolled were 1433 patients with ACS, including ST segment elevation myocardial infarction (662, 46.2%), non-ST segment elevation myocardial infarction (239, 16.7%) and unstable angina (532, 37.1%). The demographic distribution, medical history and clinical data were collected to investigate the predictive factors of RA by Logistic regression. Results During hospitalization 275 (19.2%) patients were documented with RA including unstable angina (53.2%), non- ST segment elevation myocardial infarction (27.5%), ST segment elevation myocardial infarction (19.3%). A comorbidity of dyslipidemia, prior angina, percutaneous coronary intervention (PCI) within 6 months was more common in patients with RA, P〈0.05. In the patients with RA, a significantly higher proportion of patients with acute pulmonary edema was observed, 23 (8.4%) versus 43 (3.7%), P=0.001. Acute renal failure was present in 8 (2.9%) of patients with RA versus 19 (1.6%) of patients without RA, P=0.165. Hemorrhagic events were present in 6 (2.2%) of patients with RA versus 8 (0.7%) of patients without RA, ventricular tachycardia/ventricular fibrillation events in 12 patients (4.3%) versus 22 patients (1.9%), congestive heart failure in 69 patients (25.0%) versus 94 patients (8.1%), myocardial re-infarction in 28 patients (10.1%) versus 15 patients (1.3%), P〈0.05, respectively. A lower proportion of patients with RA underwent in-hospital PCI 687 (59.3%) versus 114 (41.5%), P=0.000. A higher proportion of patients with RA received heparin, 260 (94.5%) versus 1035 (89.4%) 相似文献

Nonvalidation of reported genetic risk factors for acute coronary syndrome in a large-scale replication study 总被引:6,自引:1,他引:6
Context Given the numerous, yet inconsistent, reports of genetic variants being associated with acute coronary syndromes (ACS), there is a need for comprehensive validation of ACS susceptibility genotypes. Objective To perform an extensive validation of putative genetic risk factors for ACS. Design, Setting, and Participants Through a systematic literature search of articles published before March 10, 2005, we identified genetic variants previously reported as significant susceptibility factors for atherosclerosis or ACS. Restricting our analysis to white patients to reduce confounding from racial admixture, we identifed 811 patients who presented from March 2001 through June 2003 with ACS at 2 Kansas City, Mo, university-affiliated hospitals. During 2005-2006, we genotyped the 811 patients along with 650 age- and sex-matched controls for 85 variants in 70 genes and attempted to replicate previously reported associations. We further explored possible associations without prior assumption of specific risk models and used the Sign test to search for weak associations. Main Outcome Measures Compare each prespecified gene variant associated with ACS risk among cases and controls. A surplus of associations would imply that some are associated with ACS. Results Of 85 variants tested, only 1 putative risk genotype (–455 promoter variant in -fibrinogen) was nominally statistically significant (P = .03). Only 4 additional genes were positive in model-free analysis. Neither number of associations was more frequent than expected by chance, given the number of comparisons. Finally, only 41 of 84 predefined risk variants were even marginally more frequent in cases than in controls (with 1 tie), representing a 48.8% "win rate" (95% confidence interval, 38.1%-59.5%) for the collective risk genotypes (P = .91, Sign test). Conclusions Our null results provide no support for the hypothesis that any of the 85 genetic variants tested is a susceptibility factor for ACS. These results emphasize the need for robust replication of putative genetic risk factors before their introduction into clinical care. 相似文献

OBJECTIVE: To identify the characteristics, treatments and hospital outcomes for patients diagnosed with acute coronary syndromes (ACS) in the Gulf area. METHODS: Prospective, multinational, multicentre, observational survey of consecutive ACS patients who were admitted to 65 hospitals during May 2006. RESULTS: A total of 1484 ACS patients were recruited. The mean age was 55 years, and 76% were men. The final discharge diagnosis was ST-segment elevation myocardial infarction (STEMI) in 37%, non-ST-segment elevation myocardial infarction (NSTEMI) in 32%, left bundle branch block myocardial infarction (LBBB MI) in 2%, and unstable angina in 29%. Among patients with STEMI and LBBB MI, the reperfusion rate was 65%, with use of primary percutaneous coronary intervention in 7% and thrombolytic therapy in 93%. When thrombolytic therapy was used, the median door to needle time was 45 minutes, with 37% receiving it within 30 minutes of hospital presentation. During the first day of hospitalization, aspirin was administered to 94%, clopidogrel to 51%, and beta blockers to 65%. Angiotensin converting enzyme inhibitors/Angiotensin receptor blockers and statins were used in 62% and 82%, respectively. Coronary angiography during hospitalization was performed in 21%. In-hospital mortality was 3%. CONCLUSION: We were able to determine the characteristics, treatments and in-hospital outcomes of patients hospitalized with ACS in our region. There is room for improvement in using medications, reducing needle to door time and utilizing more cardiac catheterization services. 相似文献
