目的探讨CHADS2评分及CHA2DS2-VASc评分预测老年非瓣膜性心房颤动(NVAF)合并缺血性脑卒中患者短期预后的意义。方法调查我院2011年6月至2013年8月老年医学科216例老年NVAF合并缺血性脑卒中患者,应用CHADS2评分(0~6分)及CHA2DS2-VASc评分(0~9分)进行卒中风险评分,分为3组,低危组(0分)、中危组(1分)和高危组(2~9分),在发病后3个月时,采用改良Rankin量表(mRS)评定患者的预后,将患者分为预后良好和预后不佳组,比较两组临床资料、CHADS2评分及CHA2DS2一VASc评分差异,并进行Logistic回归分析。结果共纳入符合条件的206例(95.3%)患者,其中CHADS2评分0、1、2~6分组各31、83、92例,CHA2DS2-VASc评分0、1、2~9分组各24、78、104例,预后良好89例(43.2%),预后不佳117例(56.8%)。预后良好与预后不佳患者的年龄、性别、卒中史、CHADS2评分、CHA2DS2-VASc评分的差异均有统计学意义(均为P<0.05)。多因素Logistic回归分析显示,年龄(OR:1.23,95%CI:1.07~1.54,P=0.01)、CHADS2评分(OR:1.36,95%CI:1.17~2.36,P=0.00)和CHA2DS2-VASc评分(OR:3.24,95%CI:1.32~6.98.P=0.00)为预后不佳的独立预测因素。结论年龄、CHADS2评分和CHA2DS2-VASc评分是老年NVAF缺血性脑卒中患者短期预后不佳的独立预测因素;对于老年NVAF缺血性脑卒中早期病情改善的预测作用,CHA2DS2-VASc评分优于CHADS2评分。 相似文献

目的:系统评价CHA2DS2-VASc评分在预防抗凝治疗房颤(atrial fibrillation,AF)患者脑卒中和(或)血栓栓塞(thromboembolism,TE)发生风险预测中的应用价值。方法:系统性检索Cochrane图书馆,PubMed和Embase等数据库,纳入国外已经公开发表的有关CHADS2和CHA2DS2-VASc评分预测脑卒中和(或)TE发生风险的相关队列研究。采用Revman 5.2软件进行Meta分析,计算合并后的相对危险度(risk ratios,RRs)和95%可信区间(confidence interval,CIs),分别比较在抗凝或未抗凝治疗AF患者CHA2DS2-VASc评分≥2(高危组)和CHA2DS2-VASc评分2(低中危组)分层内脑卒中和(或)TE风险发生情况。χ2趋势检验分析各危险组脑卒中和(或)TE发生风险与评分值的相关趋势。结果:本研究共纳入12篇文献,5篇以脑卒中为终点事件(RR=5.31,CI:3.69~7.62;P0.01),7篇以TE为终点事件(RR=5.94,CI:5.48~6.43;P0.01)(Pdiff=0.55);其中4篇研究对象接受抗凝基线治疗(RR=5.43,CI:4.92~6.00;P0.01),8篇研究对象未接受抗凝基线治疗(RR=5.92,CI:5.26~6.67;P0.01)(Pdiff=0.57)。CHA2DS2-VASc评分低危组终点事件发生率明显比CHADS2评分要低(0.54%vs 1.40%)(P0.05),且将更多的患者纳入高危组(81.0%vs 46.0%,P0.05)。结论:与CHADS2评分相比,CHA2DS2-VASc评分将更多的AF患者归类于高危组,且高危组脑卒中和(或)TE发生风险更高,并显示已接受抗凝治疗的AF患者仍然存在脑卒中和(或)TE发生风险,且随风险评分系统分值的增高而显著升高。这提示AF卒中预防性抗凝药物治疗需要正确评估而规范化实施。 相似文献

OBJECTIVES: This study was an analysis of factors associated with stroke in a population of patients paced for sinus node dysfunction in a large prospective clinical trial (Mode Selection Trial [MOST]). BACKGROUND: The effects of dual-chamber versus single-chamber ventricular pacing on subsequent stroke in patients with sinus node dysfunction are not known. METHODS: A total of 2,010 patients with sinus node dysfunction were randomized to ventricular or dual-chamber pacing and followed for a median of 33.1 months. RESULTS: The median participant age was 74 years. During 5,664 patient-years of follow-up, 90 strokes (11 hemorrhagic) occurred. By life-table analysis, the rate of stroke was 2.2% (95% confidence interval [CI] 1.6 to 2.9) at one year and 5.8% (95% CI 4.5 to 7.1) at four years. The incidence of stroke was not significantly different in dual-chamber (4%) as compared with ventricular-paced patients (4.9%) (hazard ratio [HR] 0.82, 95% CI 0.54 to 1.25, p = 0.36). Multivariable analysis demonstrated that significant predictors of stroke included prior stroke or transient ischemic attack, Caucasian race, hypertension, prior systemic embolism, and New York Heart Association functional class III or IV (p < 0.05); pacing mode remained non-significant after adjustment for these factors (p = 0.37). Clinically reported atrial fibrillation after implantation was a risk factor for stroke in this cohort after adjustment for other predictors of stroke (p = 0.042, HR 1.68 [95% CI 1.02 to 2.76]). CONCLUSIONS: Clinical characteristics, but not mode of pacing, were associated with subsequent stroke in patients paced for sinus node dysfunction. 相似文献

Introduction and objectives
The risk of stroke in atrial fibrillation is heterogeneous and depends upon underlying clinical conditions included in current risk stratification schemes. Recently, the CHA2DS2-VASc score has been included in guidelines to be more inclusive of common stroke risk factors seen in everyday clinical practice, and useful in defining “truly low risk” subjects. We aimed to assess the usefulness of CHA2DS2-VASc score to give us an additional prognostic perspective for adverse events and mortality among “real world” anticoagulated patients with atrial fibrillation who are often elderly with many comorbidities.Methods
Consecutive outpatients with permanent/paroxysmal nonvalvular atrial fibrillation with CHA2DS2-VASc≥2 and stabilized oral anticoagulation (international normalized ratio 2.0-3.0) for at least the preceding 6 months were recruited. Patients with CHA2DS2-VASc≥2 were selected. Adverse cardiovascular events including stroke, acute coronary syndrome, or heart failure; major bleeds; and mortality were recorded during more than 2.5-year-follow-up.Results
Of 933 patients (93.5%) assessed, 432 were males, median age 76 (71-81) years. After a follow-up of 946 (782-1068) days, 109 patients (11.7%) had adverse cardiovascular events, 80 patients (8.6%) had major bleeds, 101 patients (10.8%) died, and 230 (24.6%) had major adverse events (composite end-point). Increasing CHA2DS2-VASc score by 1 point had a significant impact on the occurrence of cardiovascular events (hazard ratio=1.27; 95% confidence interval, 1.13-1.44; P<.001), mortality (hazard ratio=1.36; 95% confidence interval, 1.19-1.54; P<.001); and major adverse events (hazard ratio=1.23; 95% confidence interval, 1.13-1.34; P<.001). CHA2DS2-VASc score was not associated with major bleeding episodes.Conclusions
Among high risk atrial fibrillation patients on oral anticoagulation, CHA2DS2-VASc successfully predicts cardiovascular events and mortality, but not major bleeds.Full English text available from:www.revespcardiol.org 相似文献16.

In 39 patients (mean age, 66 years) treated for sick sinus syndrome (SSS) with pacemaker insertion, the long-term prognosis was studied. Fifteen patients (42%) died during the follow-up period of 6 to 59 months (mean, 25 months). Three patients were unavailable for follow-up. Eleven of the 15 deaths (73%) were cardiac-related, yet none could be associated with either an arrhythmia or pacemaker failure. Symptoms recurred or persisted after pacemaker insertion in 14 patients (mean age, 71 years), nine of whom died (31 deaths per 100 patient follow-up years). Twenty-two patients (mean age, 63 years) were asymptomatic after pacer insertion, six of whom died (11 deaths per 100 patient follow-up years). These follow-up results demonstrate a poor long-term prognosis in patients with SSS and persistent symptoms following permanent pacing. 相似文献

Aims
The HATCH score describes the risk of paroxysmal atrial fibrillation (Afib) progression, while the CHA2DS2vasc score depicts the risk of thromboembolic events in patients with Afib. We hypothesized that both scores may predict failure of Afib ablation.Methods and results
In all, 449 consecutive patients (65.5?% male, mean age 61.7?±?10.1 years) who presented to our institution for Afib ablation were investigated. A HATCH score of 0, 1, 2, 3, and ≥?4 was found in 19.6, 50.3, 9.8, 15.6, and 4.6?% of the patients, respectively. A CHA2DS2vasc score of 0, 1, 2, 3, 4, 5, and >?5 was found in 10.7, 20.9, 25.1, 20.6, 15.0, 4.7, and 3.0?% of the patients, respectively (mean CHA2DS2vasc score, 2.4?±?1.5). After 618 procedures (1.38?±?0.55/patient), 84.3?% of patients were free of any atrial arrhythmia after a mean follow-up of 12.7?±?7.1 months. The freedom of Afib after a single ablation procedure ranged between 50.7 and 60.3?% in patients with HATCH scores between 0 and 3 and dropped to 30.0?% in patients with a HATCH score greater than 3 (p?=?0.041). The freedom of Afib after 1.38 procedures per patient ranged between 79.5?% and 88.4?% in patients with a HATCH score between 0 and 3 and was lower with a score of 4 or more (66.7?%, p?=?0.064). Pulmonary vein isolation was equally successful in patients with a CHA2DS2vasc score of 5 or lower, but less effective in patients with a score greater than 5 (p?=?0.013).Conclusion
Pulmonary vein isolation is equally effective in patients with a low-to-moderate risk of disease progression and thromboembolic risk. However, the success rate seems to decrease in patients with high sores. 相似文献18.
